Core 2 Duo/DDR2 Memory Guide, Read Me First.

Theres still Team Xtreem and a few brands that have good deals with the manufacturer.

"Practically" is why I checked

I'm suspicious of the same thing. I just shelled out the extra cash and got them for piece of mind. Probably not the best buy, but whatever, I'm tired of stressing over it.

I noticed that newegg took down the link to the buffalo memory, is there any other place to purchase the ddr800 firestix?

These ?

Link still works for me. In stock too for a change.

 

[cdalgard]

Does not show in stock for me, but the page is there.

Best advice I can give (unless you are in a hurry) bookmark it, and periodically keep checking back. Forget auto-notify, its pretty much worthless for stuff that sells so fast.

Change that... they ARE guaranteed to be D9. The ballistix line is always going to use the higher quality Micron ICs (D9GMH, GKX possible).

Quick update. After sitting overnight and allowing everything to cool and resetting the CMOS and finally attempting to reinstall windows so far it looks good. I am running 2.15v on the memory vs 2.3v as before, but I am not receiving any CRC errors etc. I am running 4-4-4-12 DDR2-800 though vs the DDR2-1000 of before. I will see if DDR2-1000 is possible at 2.15v and it may be at 5-4-4-12...here's to hope. SO far it looks good. Could have been false alarm.

Yeah, i do not like running 2.3V on my RAM 24/7, & while i know you use the Dominator fan, it wouldn't surprise me if it was still running too hot or just didn't like that kinda vdimm for 24/7 use.

I am presently running 1.3 vcore, & will be seeing how low i can go for vdimm, since @ 1.3V, i can get around 3270 MHz IIRC, & it keeps temps & heat down, & will better allow me to run case closed with fans turned down.

Right now i've shifted my priority to quietness then performance.

2.15v and DDR2-1000 fails. Back to DDR2-800 4-4-4-12-4-35-10-10-10 2.15v

Still not bad...just glad it works now. I still placed a request to crucial for RMA and we'll see where it goes.

 

[n7]

Unless you're running 1000 5-5-5, i wouldn't count on 2.15V doing the job.
5-4-4 is a tad tight for 1000 2.15V i'd say.

If you loosen to 5-5-5 or 5-5-4, i bet 2.1 or 2.05V would do it.

unwilling lol

I tried 2.3v and 5-4-4-12 DDR2-1000 and it failed...so I dunno. 800Mhz is fine

 

[n7]

We already know 4:5 1000 5-5-5 > 1:1 800 4-4-4 for our mobo, so wtf would you wanna run slower...

because it won't work without voltage that's why.

this memory is 667Mhz, hand picked or not. Remember I couldn't get 4-4-4-x at 1000Mhz with ANY voltage.

The only way to make this work at ~2.2v is with HiPro Maximizer because it gives more stable voltage...I've heard that people can run timings and speeds at 2.3v that took the mobo alone 2.5v to achieve. It's a more stable and clean power for DDR. But I don't want to buy it.

 

[n7]

I hate sounding argumentative, but i still have yet to see where you find evidence of certain kits being hand-picked & others not.

If i could find info to back that, i'd be more than happy to support than claim, but till then, i am gonna assume that really only happens for the insanely high end RAM like Corsair's fantabulous stuff.

Every D9GMH kit in existence was designed as a 1.8V DDR2-667 5-5-5 part originally IMHO...mine included, & i can do well over 1000 4-4-4, though i'm not sure how much vdimm i'd need for actual Orthos stability.

Also, have you tried running things off the 1066 strap for stability?

I can't even boot at 400...have to jump to 401, & i know there's a hell of a lot of mobo stress at 400.


Now that being said, i have i PM for you regarding really weird sh!t happening on my P5B lately...

 

[memories2002]

Ive got Transcend 667mhz Ram that says "D9DCL" on it....any info on these?

 

[The-Noid]

Just got a hipro maximizer yesterday, I Am intrigued to see how this will work.

 

[Cali3350]

Does anyone have any experience with the Geil memory linked at the beggining of this thread?

http://www.newegg.com/Product/Product.asp?Item=N82E16820144028

I have access to a pair and am curious what its performance seems to be.

 

[The-Noid]

If you want 800 mhz and 4-4-4-12 timings it works, if you try to go further it won't.

Looking to buy by this weekend to complete my e6600/evga 680i build.

I had been mostly considering between the pc 6400 and pc 8000 ballistix. With the OCZ stuff having gone on sale this week, I"ve also added some of those modules into the mix. (Ocz2g10002gk, ocz2p800r22gk).


What would be best for the system I posted above, a primary gaming rig with no to mild OC'ing (at least for the near-foreseeable future).

Search around on xs some posts there said that crucial claims the 10th anniversary to be selected specially for that memory.

Either of the Crucial offerings are better value (OCZ can't guarantee D9 ICs even at 1000Mhz)

Yeah, on my limited research of these chips via my palmtop it seems neither of those OCZs are listed in the micron d9 charts.

Since it looks like Crucial shall be the pickings, what difference is there between the pc6400 (with lower default timings) and pc8000 (higher speed but also higher default timings).

Well, the difference is that some of the ICs used on the PC2-6400 offerings are likely ICs that did not pass whatever testing they do to certify them for PC2-1000 operational speeds. That being said, almost every D9 memory can do DDR2-1000 at cas5 and some at cas4. There is a likelihood of the 1000Mhz part going beyond 1000Mhz as well.

Depends how far you are trying to push the clocks on your memory.
