so if I'll buy a 6600 core2duo I need PC4300?
and if I want to overclock to 333 fsb I need a DDR2-667?
what for are the ddr2-1000?

If you run everything at stock, then they'll do.

However, most people will use ddr2-800 at stock cpu & fsb, using the 3:2 (ram:fsb) divider.

If you wish to overclock, good ddr2-800 or above is what i'd recommend

You should refer to the basic overclocking guides here for more info

I'm new at overclocking so is the ram effected when the cpu is overclocked?

[Phalkon30]

Not always, but usually yes.

Yall good deal micro d9 gkx <-- the best stuff also 2.5v warrnty good o/c http://www.newegg.com/Product/Produc...82E16820150043

<----------I have the spec as it says left.

Would the timings 3-4-4-8, 2.5-3-3-5, or 2-3-3-6 be most ideal for me, I use my machine mainly for Gaming, and Video editing etc...

Which would be

a) The most powerful?
b)The most expensive in a 2GB kit (2 x 1024mb)

Cheers

2 3 3 6 are the best timings out of the few you gave.

I take it you're looking at a couple of kits then?

Please post what kits they are with a link to each.

Timings are also dependant on what speed the ram is intended to run.

i.e. the 2 3 3 6 kit could be DDR400(200Mhz), but the 3 4 4 8 kit could be DDR500 (250Mhz)

Ideally, you want a good kit of DDR400 with 2 2 2 5 timings.

I started reading the original posts for this thread and noticed it was written in 2004. I've stopped reading for now at the beginning of Wilds second post, which covers overclocing RAM, but since it is so old I am not sure if the information is still considered up to date. Should I continue reading or would a more recent guide serve as a better learning tool? I'm building my first rig and before starting to read this guide knew virtually nothing about RAM other than "Corsair ROCKS" which I'm questioning now thanks to the post .

[WildStyle]

Yes it was originally written in 2004 but has been revised many, many times since then. Look for the "last edited by..." message at the bottom of the posts.

Everything in the guide still applies, all the generic info still applies to the RAM thats around today. All the "how does this work", overclocking methods, all the timings, how to shop for ram etc, that stuff, is all the same. It's just that all the specifics on certain modules/mainboards were written for 939/DDR rather than the 775/DDR2 that's at the high-end today. That's why I added a post at the end about Micron DDR2 in particular.

I haven't seen a more comprehensive guide on the web although there probably is one. This one won't be updated anymore. I know Ive said that before and then updated it but I dont even have a desktop PC anymore so thats that really.

Good to hear it's helping you anyway, that was always the intention as I just wrote down everything I had in my head.

[Dublin_Gunner]

The guide is still VERY relevant.

Fact is, there's little in the difference (to most users) between DDR & DDR2, even when overclocking.


DDR2 essentially runs at the same speed as DDR, its the mega transfers per second thats doubled, so all the info on overclocking and dividers is essentially the same, you just double up the final number (in simple terms).

Wildstyle, where's your rig gone?

[Mulsiphix]

Very glad to hear it is current. It was such a good read I couldn't help but finish reading it last night. It has helped me to understand RAM a lot better. I'm still having issue on picking out RAM for my new gaming rig. The timings really throw me off . I really appreciate the guide though and am very sorry to hear your no longer have a Desktop PC.

I've already started another thread with my questions so I wont duplicate it here, would have posted here but wasn't sure if Wild was still around, but if anybody wants to shed some light on my troubles it would be most appreciated.

Core 2 Duo + New RAM = Confusion X_X

Sold it out of my own choice. I've had very little interest in hardware for a long time now, so I finally bit the bullet and sold my PC because I now pursue other hobbies & interests, and have less time in general. So if you fancy continuing to help anybody that posts in this thread, Dublin_Gunner, that'd be most appreciated mate. Right, enough about me.. lol.

Happens to us all at some point I suppose!!

I'll keep an eye on the thread anyway. It doesnt get that many posts these days, but I still recommend it to folks looking for guides.

[Mulsiphix]

The thread was extremely helpful to me. Only thing I think it was missing was a more in depth section for people looking for quality RAM that plan to run it at stock speeds. After reading the guide I wasn't sure if I should just go with Value RAM, if the timings were important at all, or if the chips that came on the RAM were significant since I would be running at stock. After some questions being answered by the fine folks over in the General Hardware section of Guru3D, I was ready to purchase .

[Dublin_Gunner]

Genreally, if you're running at stock, even value ram should be fine, but value ram from a known brand.

Remember OCZ value RAM with Winbond chips? Thats what I call a good Value RAM.


BTW, I dont post anymore (ar at least as I used to) here at Guru3d...
I cant find pretty interesnting many things with hardware now (I feel AMD 939 was a lot more fun than now, with horrible prices for RAM and memory as long as many other things...)

Anyway, I will be posting at this guide also if help needed.

WildStyle.... any chance you will feel like posting again with DDR3? maybe?

Greetings bro.
Enjoy.

I sure do, nothing like cheapo BH-5's eh??! Geil Value ram also had BH5/6 depending on the batch.

[iron_gr]

Well, I bought these http://www.diy-street.com/forum/show...&postcount=747

It only says -5B

Can someone help?

Help with what m8?

Hi there!

I don't know if it's micron or not!

Ah ok!
I cant seem to find any info on them anywhere, but at least the PCB is brainpower.

Looks like they're micron 5B-D. Not a very reliable IC, and built on an odd manufacturing process of 95nm

Sort opf unlucky as some of them come with Winbond BH-5 IC's, which are great overclockers with enough voltage

[jonerkinsella]

ive gone and bought this ram todayits micron PC2-6400 Ballistix
4.0-4-4-12 @ 2.2V
Micron D9GMH (B6-3)
or
Micron D9DQW (BT-37E)
i got it in komplett for what i think is a reasonable price
http://www.komplett.ie/k/ki.asp?sku=312367
ive checked it with the ram guide posted in wilds guide and it says its micron.

[Dublin_Gunner]

Joner, you should have went to memoryconfigurator.com


You might spend a bit more, but you can be guaranteed GMH on a fair few kits there, plus, they're based in Kildare

[jonerkinsella]

i tried them but they wernt sure about the modules i was asking about. the only d9s they were sure about were 50euro more,
these 1s http://www.memoryc.ie/products/descr...kit/index.html

according to this guide they should be micron d9s
http://ramlist.ath.cx/ddr2/

i hope they are now that ive bought them.

[Dublin_Gunner]

I'm sure they'll be fine, great price for D9's

Not sure how those DQT/DQW D9's are clocking.

Anyone got any experience with them?
