Asus P5Q Bios & fastest cpu

[Optikn3rv]

I have a P5q mobo in this rig and was looking at updates to the bios but I am confused. using Astra it says my bios is 80.00.14 yet looking on the Asus site it says 2209 is the latest, in fact I cannot find any reference to the bios this mobo came with. Anyone know if 80.00.14 as a different bios code on the official site? Reason for updating the bios was to see if there was any cpu support updates as I want to look at a faster cpu then this intel core 2 quad Q9400 2.66mhz.
So basically I am looking for 2 answers
1. what bios is 80.00.14
2. fastest cpu for this P5q (775)

hmm just loaded cpuz and it shows the bios is 2209 so would seem Astra gives weird info.
Cpuz also shows my Q9400 running at 2003mhz so there must be room for a tweak to get that faster. I'll scan the forums for O/C'ing a Q9400

I have a P5Q motherboard and Q9400... lol. Yeah latest bios is 2209. I recommend you try the Ket modified bioses though, as they perform better than the stock bios. They're a bit hard to find now though...

The easiest way to overclock is to ramp up the FSB to say 405, above that you start to go into an area requiring voltage changes etc. Remember to adjust the memory clock to match, so you don't overclock your memory beyond its capabilities.

just googled the Ket bios and seems he stuck them on mega upload and as we all know they're down. Are you running o/c'ed if so wat speed are you at.?

[Optikn3rv]

Weird in the bios i cannot change CPU ration its stuck on auto.
Below is a screeny of the bios and cpuz
hmm seems photobucket sticks it on its head lol dont get neck ache tryingto view it.

You have to set AI overclock tuner to, from memory, 'manual'. Don't mess with the multiplier, the CPU is multiplier locked. The only reason why you would want to change it is to set it lower and have the FSB really maxed out with high voltages etc... (I don't recommend that).

CPUz is showing the multiplier at x6.0 due to speedstep. Basically the multiplier can ramp anywhere between x6.0 (for power saving) to x9.0 (maximum speed). Its also why the CPU voltage is showing a little lower than normal.

As I was saying before, change it to manual, change the FSB to around 405 (about what you can manage without fiddling with other settings), change the memory speed back to a realistic value (it jumps between values, choose the closest). On top of that, you can set the AI transaction booster (too low of a level will cause the system not to boot, but with these boards the computer will automatically turn off, turn back on again at default settings and allows you to change it. '7' may be the value to choose (try 6 and lower though, as the lower the supposedly better). Those other settings can either be maxed out for performance, or changed for compatibility. Since you aren't going to a ridiculously high overclock I recommend opting for performance settings.

Any higher than around 405 for the FSB requires much more meticulous tuning, better cooling, and will actually potentially shorten component lifespan. Thats still an almost 22 percent overclock! So the 'equivalent' of a i5-2500K at 4.5Ghz, in the sense of overclock above normal. Some people reckon they have managed much higher overclocks in terms of FSB etc, but that begins to put a lot of strain on motherboard components. 405Mhz is fine though . If you want to, you could stick with just 400Mhz - its still a decent gain.

yuk wont boot I tried FSB 405 and AI boost 7 then 6 had to pull the plug and when I start and go in to bios setup it mentions the overclock failed.
Tried the mem on 811mhz and 1632mhz and auto but it dont like it. Not sure what stops it booting.

well. i also have an P5Q and i love it..i use teh Ket´s BIOS..i searched but i didnt find em on my drive..if u know how i get it copied form my bios i can upload it for you..

im stable at 3.8 ghz and an FSB of 447...



Everything set manual..i could make screens from my bios so u know all the settings if u want me to do that...

Several games don't like FSB overclocking.

BFBC2 was one of them and so is counter strike source. Keep that in mind

[thatguy91]

Depends on how high you have the FSB set. The Q9550 should get a higher clock than a Q9400. The difference in the cache can be made up somewhat with the higher FSB, so its definitely worth it.

[Optikn3rv]

Beta if u can post ya bios settings it would help get an idea what I am fiddling with ;-) I will keep looking for the KET bios but as they where on the closed down storage sites It might be hard to get.
FSB 447 might mean to much fiddling other settings for my skill level but as 405 sounds good would be interested to find out why mine wont boot.

[BetA]

oki doki..im on it...ill be back in about 10 min. or so..im gonna make the screens and ill try to make a copy of my BIOS so u also have Kets m bios...the one i have on it..

greetz BetA

ok, here we go...Im using these settings now for one year or more and its stable and the temperatures are good too...But u will need an good cpu cooler...

I also can make an backup of my BIOS...its teh 2002 Kets m-bios im using...So if u want it let me know..then i need to grab my USB stcik

ok, as promised, here are my Bios settings:
( ha u also got the same RAM then me, haha..GREAT CHOICE mate...)












lemme know if it works and if u need teh bios also...
some info from my side..i have 8gb ram , so all my ram slots are full..thats why i had to set fsb and NB voltages manual..it takes a little more when u use all ram slots etc..

well, i hope that helps u and some others here...

greetz BetA

edit:

and for the other question, whats teh fastest cpu for socket 775..
well..id could say the 9650 since it has a slightly higher Multi..But i also had teh same question when i bought my cpu back in the days...and well..it really doesnt make much of a diff..if u can OC the Q9550, they are pretty same..they both got around the same OC limit and behavior...at least from what i was reading and looking at when i bought mine...

greetz^^

[Optikn3rv]

cool cheers I'll have a fiddle, I got 8gb ram to but the other is kingston, couldnt find another 4 meg of what I had. Seams slower to then my ocz.

I am not to hard core to mess with voltage etc afraid i'll fry something lol.

right used most of what you have and got the following
Default settings


slight tweaking



as you have a slightly different cpu do you think copying exact settings would run on this cpu or might it be just too much?

[BetA]

first, u should make the screens when ur cpu is under load..so it wont throttle..that way we can see teh actuall speed hehe..

and no im not shure if using the exact settings is good..what is ur max multi?
and my guess is that u can use a lower vcore since u wont go for 3.8 ghz..test around alittle..start with lower numbers..
Also what is ur temp? in idle and on load?..use prime or intel burn test...something like that..

I notice you haven't enabled the pull-ins? doesn't it work with them enabled? also AI Clock Twister on stronger (I think thats the highest) works for me, don't know it it is any better or not but sounds cooler

[Optikn3rv]

Right I just ran intel burn in here's a screeny with temp before the test.
Got to 3299.99mhz



and during the test about 4 minutes in



PC probe gave a heat warning and temp did go to 86c then the cpu speed dropped to 2430 again so I presume it throttles down when getting to hot which sounds normal.

[thatguy91]

Wow, what heatsink do you have on the CPU? It shouldn't have got that hot at 3.3Ghz! For any overclocking, at least an 'okay' heatsink and good thermal paste (something you should definitely get a good brand of) is essential. If you already have these, I would suggest your need to dust off your heatsink, clean of the thermal paste in place, and apply a good thermal paste (very sparingly, it needs full coverage at the thinnest possible thickness).

It might sound stupid, but your CPU should never overheat no matter how hard to press it. An overheating CPU is a good sign your cooling is wrong. This is true unless you stuff up the voltages badly somehow. When doing ultra high overclocks (405fsb is a reasonable but 'safe' overclock for the q9400) the computer should become unstable before it overheats

EDIT:
I notice your core voltage is pretty high, that won't help with heat! Mine runs fine at 1.272V. You should only need a high voltage like yours if you were uberclocking (much higher CPU speed than what you are trying to obtain).

[BetA]

Hy there Guys...

i succesfully extractet my Kets MBIOS for asus p5q (2002)..
Here it is for the ones looking for it...its the one im using and its stable and great for over a year now !!!! Great OC potential, etc etc..

standard heatsink that came with it, also didnt touch core volt thats standard to. Though I can always hunt around for a nice heatsink.

[BetA]

yep, buy an aftermarket cooler...u can get good ones for 30 euro allready..then u should have no problem with heat...

my max temp is around 62 C° on the cores under intelburn test...thats pretty good and enough safety room...

[Optikn3rv]

well I just ordered a SCYTHE MUGEN 2 REV. B. SCMG-2100 reviews seem good even noise is acceptable so once I get it in I'll stress test it and see what temps are.
Also just gonna reboot and set the core voltage to 1.272v.
