Psychlone have you ran into any articles about motherboards having problems with the wattage demand of the Phenoms or 125 Watt X2? If so what's your take on it. Do you think the manufactures just used cheap caps that can't handle it or what?
Actually i wouldn't exactly say that.... your 6400+ at 3.2Ghz is pushing it even there at stock, 3.3Ghz was all i was able to get my 6000+ to except when i got this latest board, but this board is 240 dollars, so i would say that you OCing to 3.3Ghz is just fine and is very normal

I am curious as to where your X2 overclocking guide is. I REALLY want to see what this 6400 BE can do (i dont even mind going insane and trying for 3.5ghz lol)..So any info or anything would be awesome.

And man your phenom guide rocks but im waiting for denab...my 6400 BE should tide me over tell then.

Thanks

First of all, thanks for the props - it took a long time and a lot of CMOS clears to get to the point of writing up the guide, but in the end, it's already helped lots of people with their overclocks.

The M3A79-T BIOS is identical to the latest M3A32-MVP BIOS - with the addition of ACC - (which will answer your first question) - ACC is the communication between the Southbridge and the 6 previously unused pins on the bottom of the Phenom CPUs - so to my knowledge, it's not actually doing anything for you.

The X2 overclocking guide was written specifically for the A8R32-MVP motherboard, and you'll find that it's almost identically written to this M3A32-MVP guide with the math changed to reflect the different architecture.
Here's that A8R32-MVP Guide that you'll want to pay specific attention to the math to...it's only a little bit different. Where you don't have a Phenom in the socket - you're going to want to keep your HT as close to 1000MHz as you can (the older architecture can't handle the 5200MHz that the Phenoms can) - and when you're doing the math for the Divisor Ratio, you're going to have to remember to ROUND UP to the next higher whole number - something that's changed in the new architecture...this means that even if you land on a decimal that's lower than .5, you still round up to the next higher number (i.e. 12.1 = 13, 12.2 = 13, 12.3 = 13 and so forth)

Be patient and keep an eye on your temps - as soon as you begin playing with voltages, all the excess heat generated by raising them has to go somewhere, and that somewhere is usually your CPU HS/f assembly and your motherboard's chipset, and with the M3A32-MVP and the M3A79-T, it's also going to heatsoak the VREGs (voltage regulators on the far side of the board right under where your exhaust fan probably is - it has a copper heatsink on it that may need some extra cooling - the M3A32-MVP came with a little specialized fan that mounts directly on the copper fins, but they left it out of the M3A79-T box for some reason. - Nothing that a small fan pointing right down on them won't fix...and you can (and should) monitor their temps in Everest.

Good luck to you! If you've got any questions after giving that A8R32-MVP thread a thorough read, please feel free to create a new thread and pm me the details of where it's at and I'll come pop in and see what I can do for you.

Thanks for the props on the guide!
As for the decreased overclocking ability on your current M2N board - it's not really about the caps on the board so much as that board was made before the Phenom architecture was revealed (if I remember right) - it probably took a BIOS update to become Phenom compliant, but there's really nothing that they can do in the way of voltages and wattages for the newer architecture CPUs since the board wasn't built with the newer architecture in mind in the first place.
If you're in the market for a really good overclocking board for your Phenom, the M3A79-T can be had for less than the M3A32-MVP right now (just under ******** if I'm not mistaken) - and it *will* take your CPU to it's max...just remember that it's only going to do as much as your CPU's stepping is going to allow - stepping has been an all-important variable in overclockability since AMD was founded, and still has the largest impact on how high the CPU is going to overclock...it has very little to do with anything else (since the RAM, HT, NB can all be taken out of the equation by lowering them or putting them on dividers)

Anyway, good luck in your quest for an overclock on your Phenom - I'd suggest the M3A79-T board since it's already Deneb compliant (140W CPU)...but if you want to wait for a few months, the new AM3 boards will come out (personally I wouldn't wait since the new architecture is bound to have some growing pains right out of the box when it's released - better to wait till some BIOS updates are available to alleviate the problems that are inherent to new hardware)

As far as I can see, my board doesn't turn phenom cores off. So I've instead used AOD to downclock a core to 1ghz, using a 5x multiplier, for better temps. Anyone know if this is going to affect me at all? I know Vista will try to spread things across all the cores, obviously one of them will be significantly slower.

I am from the days of yore when an Overclock was done with a jumper or some well placed solder. The extreme overclocks were done with temporarily with jumpers and bags of ice, almost always ended up in disaster.

I have done some overclocking on newer AMD stuff and here is what I have gotten.
Gigabyte ga-m57sli-s4R2 and 5200+ x2 at 3.003 Ghz with 4GB DDR 800 (G.skill)at 920mhz 4-4-4-12 timings 231 FSB and 13x multiplier. M3N-HT Deluxe and phenom 9950BE at 3.003 Ghz with 8GB DDR 800 (G.skill) at 920mhz 4-4-4-12, same FSB and Multiplier. I have gone up to 240FSB but it just locks up.

do you think I can get more out of either one of those with a CM690 case and all 120mm case fans and stock coolers? Would it be worthwhile? I just don't understand the whole FSb*HT=DDRspeed/cpumult^htMult stuff.

I could do some digging and give you specs an all the hardware if you wouldn't mind making some suggestions on the other items. Like how to set the cpu multiplier so that I don't over do my ram and make that freak out etc.

2.9 might be your max, without a Black edition processor. My 9850BE only hits 3.1 stable, and 3.2 if I can get better cooling.

If you don't have a Black edition, you can't change the CPU multiplier upward, only down.

No offense meant by my post, but I find it quite odd that my original thread when Phenoms came out was not stickied when it had all of the information in it minus the stuff specific to the M3A32-MVP, and it had a bit of information about what kinds of cooling were better for your phenom. But since this one is stickied I'd recommend finding it and adding the information about specific kinds of cooling.

@ OldGuy: First, I'd like to thank you for your input in the early days of my Phenom testing.
Since I can't sticky anything, and it's up to the mods, I most certainly can add your information to my original post as an addendum with due credit...if you want to find that post of yours (I've searched, but there are a lot of posts that contain Phenom in them!)
...let me know.

@ XFGolden: Your CPU's stepping is going to be the first limiting factor, followed by your board's overclockability, then by your RAM. Lots of the Phenom 9950's can't even hit 3GHz at all, so don't feel as though you've gotten screwed - remember the first rule of overclocking: Don't expect more than what you've paid for. This obviously means that you're not guaranteed anything more than the component was designed to do stable.

Another thing, with the Phenom architecture, I've found that it's easier and more proficient to overclock using the unlocked upper multipliers on the Black Edition CPUs rather than the older architecture's overclocking of upping the HTT (FSB) with a lower multiplier. Since all the individual components are now linked but have multipliers, you can set them almost anywhere you want them without having to rely on the FSB to raise them to a certain level (or to drop them lower to compensate for the raise in FSB) - simply set the multi for whatever component you're currently overclocking (HT/NB/SB, etc.) and there you go.

With the new M3A79-T Deluxe motherboard, I've achieved a 3.675GHz overclock, but it wasn't stable at the voltages I preferred to run (it would be at higher voltages, but then the heat would have been catastrophic) - I did an AOD hack to allow higher voltages but even though I believe that I could have been stable at that speed with more juice, I backed off after I saw the load temps in the mid 60*C range.

Anyway, again, it's all about stepping - as it's always been. I, too, have been around since the 'olden days', and not much has changed...the math, the architecture, the ability to overclock via BIOS and now via Windows apps all make the venture into overclocking much easier than it used to be.

Good luck!

I noticed you and others have the ability to disable cores in your bios. I'd like to give this a try...is the setting hidden somewhere, or is my board without it?

Hey Psychlone. Just bought a foxconn destroyer nForce 780a SLi as an upgrade to go hand in hand with my phenom 9850BE. I read in one of your posts that you have previously used a foxconn mobo. so i was wondering if there anything more specific to that brand i should know before following your guide? sorry if it comes across as a dumb question, i've only just started looking into overclocking so im a bit wary of what i should and should not do, aswell as what i do and don't have to know.

thanks in advance.

Edit:

i forgot to mention/ask. the new motherboard arrives tomorrow and the one i am using atm is the Gigabyte GA-M750SLI-DS4 along with 4x 1Gb dual channel ddr2 pc2-8500 mem sticks (http://www.ocztechnology.com/product..._ready_edition) which, according to their specs, can run at 1066Mhz.

However i have run cpu-z and get some very different results - i have not bothered with overclocking this board or any of the hardware attached to it atm. Here are the memory results using CPU-Z v1.47:

Memory = http://i25.photobucket.com/albums/c9...eaD/Memory.jpg

SPD = http://i25.photobucket.com/albums/c97/WolfzheaD/SPD.jpg - All 4 slots are showing the exact same feedback from cpu-z (running at pc2-5300)

As mentioned before the system is completely standard, theres been no overclocking done and although i am getting my new mobo tomorrow i will be using this Gigabyte one as the foundation for my gf's new computer in a few weeks time and ideally i would like all the hardware to be running as it says "on the box"

I'm not really sure if it matters but im running 64-bit Vista? perhaps cpu-z doesnt work too well with 64-bit software - i dunno.

again thanks in advance for any info :-]

Hello Psychlone, I recently bought a set M3A32-MVP DELUXE + AMD PHENOM 9850 BE + 2x 1GB Corsair Dominator 5-5-5-15 + COOLER Zalman 9700 LED and Power Supply Satellite Model : SL-8600EPS-Modular 600W.
Only that I am very disappointed with the OverClock that attained so far, only 2610GHz, this is too little for what I see here, but actually increase the clock if I do not have stability. I'm using Vista 32bit.

Any idea?

I would say that the phenoms really don't take to having their fsb increased. You'll want to do all your overclocking, or most of it anyway, through the multiplier.

@Iarwain: I have no experience with the DFI version boards, so I can't say one way or another if the option to disable cores is in your BIOS or not, but what I can say is that it seems to be a fairly standard feature in most BIOS revisions nowadays that are the AM2/AM2+ boards, so there's a good chance it's in there somewhere...(sorry I couldn't help more on that, but I won't speak unless I have first hand experience with it.)

@WolfzheaD: Your first screenshot shows your RAM at 533MHz, which equals 1066MHz DDR (you have to remember to multiply it by 2 when you see that)
The second screenshot shows PC2 5300 because the 1066 sticks don't follow the standard JEDEC compliance standards, so don't worry about that...it's really running at DDR2 1066 speeds.

As for the Foxconn board, I don't like Foxconn's BIOS, nor their BIOS updates...mostly why I've stuck with ASUS almost exclusively. The Foxconn BIOS is lacking many of the feature that the ASUS has, so finding the same variables in your BIOS may get confusing...and I don't know if I still have the notes for Foxconn boards or not.

About specifics: DO NOT raise any voltages very high...I wouldn't go more than a half volt (.5V) higher for any single voltage than I have in this guide...and I mean that! If you raise your voltages (any of them) too high, you're bound to burn something up. Other than that, you're pretty much safe to do anything. If you raise the FSB up too high, you'll bluescreen or just not POST, in which case you'll reset the CMOS and start over (and not make that mistake again) - if you raise your multipliers (any of them ) up too high, you'll bluescreen or just not POST, and you'll be clearing your CMOS again (and won't make that mistake again) - all in all, everything can be cleared by wiping the CMOS and starting from scratch, but raising any voltage too high can and will cause component damage that clearing the CMOS won't fix...so you're free to do what you want as long as you keep those voltages in check.

@magah: Don't get too frustrated this early on...you haven't tried much yet (I presume)
But, please do keep in mind that not every CPU will overclock to 3.5GHz. You paid for 2.5GHz, and that's what you've got - a CPU that's guaranteed to be stable at 2.5GHz (never forget the first rule that you shouldn't expect more than you paid for!)

But, I believe that we can get you more. Just how much more depends on the stepping of the CPU you have there. Stepping is all-important, and determines just how far you're going to be able to go. A horrible stepping will still do 2.65 - 2.7GHz, where a good one (like mine) will do 3.675GHz if tweaked properly. It's all about when it rolled off the manufacturer line, and that's what's marked on the IHS on the top of the CPU.

So, let's say "hypothetically" I want to get a 9850 or 9950 BE from a site like newegg or zipzoomfly. Is it a grab bag of processors laying around in their warehouse or can you actually request a certain stepping?

*If the answer is "random", where could one go about shopping for the chips with the best stepping? I'm talking NIB, not used.

I see you've already moved on to the m3a79, which is what I currently have in my sights (I mean "hypothetically" in my sights ) as of now. How's that board treating you (and your overclock)?

Finally, is that Vista you have 64-bit? Can't believe I never asked you that in any previous exchanges....

cheers psychlone :-] i had a little run through your guide up on the laptop whilst trying some of the overclocking on the gigabyte board, i couldnt get the 9850 above 2.8Ghz stable but im not sure if that due to the limitations of that gigabyte board, anyways new one just arrived so time to go rebuild this rig :/

thanks again mate

Not that stepping, the actual stepping on the chip (i.e. JAAHB AA 0816 GPMW
)....

Is there any way to shop by this stepping?

Also on my M3A78-T, the SB PLL spread spectrum seems to help stability a bit, mostly because I can't boot up at 263x11.5 on my 9600 unless its turned on.

Hey cupper!

Unless you physically hand-pick one, you'll get whatever they send you. I've found that Newegg usually has the best steppings on hand, but that doesn't mean that you'll get one - I went through 4 from Newegg...1 of them was a decent overclocker, 2 of them were *horrible* (2.8GHz was their highest!), and 1 of them was excellent at overclocking (the one I'm still using, and it's reached 3.675GHz on this board)
I've found that Fry's Electronics has an excellent selection that you can 'cherry-pick'...that's how I got the RAM I have in my rig...they just happened to have revision 1.3 Dominator 8500C5D's on their shelf (about 4 packages back) - these sticks are stable at well over 1200MHz, but Corsair quit making them a year ago...so only places that have the old stock in their warehouses are actually going to even have access to something like that.

so, hypothetically, if you purchased a 98 or 9950 BE along with an M3A79-T Deluxe and 4GB of Corsair Dominator 8500C5D sticks that just happened to be version 1.3 to 1.4...then you'd be happy as all nine planes of Hell with your setup! I know you just, and I mean *just* got your rig overclocked nicely and are happy with it. You know that you'll never get out of it what you've got in it unless you use it up, so my suggestion to you would be to hang tight until the Deneb architecture comes around the corner, then make the purchase...it should be just above $200, the M3A79-T should be just below $180, and the RAM you can find for pennies these days...
The Deneb architecture isn't only a die-shrink, it also packs a 15% performance boost, and a couple testers have already taken it up to 4.5GHZ + ...just something to think about.

My OS has been Vista Home Premium x64 for about 6 months now, was Vista Home Premium x86 for the 6 months before that, and XP Home x86 for the 2 years prior...so when I was helping you with your A8R32-MVP, I was on VHP x86.

@Iarwain (and anyone else that's confused about steppings)
You can break down the stepping numbers/letters on the top of the IHS so that it shows the date the actual chip rolled off the manufacturing line. This is how important it is to know what you're getting; very few Phenoms with a stepping of 0810 or before have shown to overclock higher than 2.8GHz. Most good overclocking Phenoms (3.1GHz or above) come from weeks 16, 18, 19, 21, 22 and the weeks that I have skipped are Phenoms that have extreme difficulty reaching 3GHz even with extreme voltage increases. Also, the steppings of AW, GW, and MW have shown to be in the top of the best overclocking CPUs. (highest MHz with the lowest voltage increase)


What we call the 'Stepping' is really quite a lot more than that...we usually can group it into 5 categories from those numbers:

* Core
* Week
* Stepping
* Color (of PCB)
* Revision

The 2 that are imperative for the Phenom are the Week and the Stepping, the Week that it was created, probably due to the manufacturing process itself (like a 'Wednesday's Car' - a car built on Wednesday used to be the better car because during the middle of the week, no one was looking forward to the party at the end of the week and they had already nursed their hangover from the weekend before )

In any case, if there's a way to physically hand-pick your CPU from a dealer, that's what you should do, even if it's more money - because there's no way to tell what you'll get from any online retailer.

Hey Psychlone, I have my phenom 9950 running at 3333GHz (202 x 16.5) and it just feels like a great sweet spot to me but it will crash during the second 3DMARK06 CPU test and the AOD stability test.

I was just wondering if you could give me some tips or suggestions as to try and stablize what I have so far with my settings, as it runs much cooler at 3333MHz@ 42-45C idle than the default settings @ 2600MHz which is 48C idle (both of which are when ambient temps are about 26C) I am idling at 39C right now however which I think is really good.

Other overclocks I have tried were very toasty and just plain didn't feel very zippy

I really like this overclock if I could get it stable.

Done so far:

Changed the CPU multiplier, FSB and CPU voltage to (1.375v in BIOS) which shows up as 1.39 on Everest and other programs.

Set NB voltage to 1.21v

Changed 2xLCLK Mode to [Enabled]

Everything else is pretty much defaults.

ALSO, I would like to know what you meant when you were talking about Microcode Updation.......I guess my BIOS just simply doesn't have that option or something.

--------------------------------------------------------------------------------------

System Specs:

AMD Phenom 9950 (not sure of the steppings as I didn't look at them)
I unfortunately have a mix of 4GB RAM : CORSAIR XMS2 DDR2 800 2GB (2 x 1GB)/OCZ
Cooling (Stock)
Platinum 2GB (2 x 1GB)
Asus M3A79-T Mobo
Radeon HD 4870
Sony DVD
Corsair 750 TX PSU
Antec Nine Hundred Case

Hi, my phenom 9850 processor has step number:
JAAFB AA 0809EPDW
Its possible overclock with it?
Because I'm not getting more than 100MHz from OverClock.
The maximum value that computer stay stable is 2650MHz with this PHENOM 9850.

@magah: Lowest 9850BE on the charts with that stepping is at 2.8GHz, so perhaps you need to raise your CPU voltage?
My first question to you would be: Have you tried to find each individual components MAXIMUM value as per the guide? If not, thats where you need to start - because without knowing just how far anything will go, you wont know how far you can take anything!
Go back to page 1 and re-read the section called "Finding your Maximum Values" - you're sure to have better results when you know a little more about what you're doing.

@goitalone: DISABLE 2xLCLK mode...thats not doing anything without the other options that go with it, and even then, all of them hinder a decent overclock.
If you know what stepping Phenom youve got there, nows the time to tell me, because you may be capped at 3.3GHz at 1.375V. Once you start going above 1.4V, Ive found that it really gets to the diminishing returns point quickly...and youre almost there.

Microcode Updation requires you to press F4 under the "CPU CONFIGURATION" area...its a hidden option.

Aside from all that, the only things that I can tell you to do (since I really have no idea what youve already done) is to raise your CPU voltage a notch, set your RAM timings manually just as theyre supposed to be, and test again. Get back with me with more of your settings...you could just copy and paste your BIOS settings using my template on page one.

I just now got my CPU back in.

Sure is hard to take a good pic with a crappy web cam and poor lighting, but I really wanted to take a picture instead of just typing it out, so I did

Well, anyway, here is my Phenom while I go write down all my bios settings:

I'm worried about you saying that, because it is so unbelievably unlikely that your computer idles lower at 3.33ghz than at 2.6, and even if it does, load temps are what matter. Unless of course you've found the only CPU that gets cooler the more it is OCed.

EDIT: Is there any way to get all the stepping information in a software based way? I really don't wanna pull it out again. First time I bent the pins somehow.
