DDR Revisited

CORSAIR TWINX2048-3200C2PT (Rev1.2)

I am trying to find out out a bit more about this Corsair TwinX kit, according to the ramlist website it has:

Infineon BE-5 Brainpower PCB

I am not familiar with either BE-5 or Brainpower PCB (although I heard people here speak about Brainpower before).

Can any of you old-school memory experts shed a little light on this please? I am just wondering what these sticks are capable of on average?, characteristics etc?

Also what's so good about the PCB?

I am testing them right now on an Athlon64 system but it is taking a while and it would be good to have some idea of what I am working towards. The CPU-z screenie above is how I have the sticks set-up at the moment using 2.6vDimm which seems good, I don't think they can do 2-2-2-6 etc but hopefully they will overclock a bit higher than 200MHz?

Insights, tips, gibberings from Corsair Zealots appreciated!

Many thanks!

you are undervolting them by some margin which might explain why you can't get better timings.

Who says I can't get better timings?

I have stuck the sticks in an completed stock testing at 2.6vDimm which I'm pleased with, ideally would like to keep the sticks running on low power.

Just been doing some Max MHz testing at 2.6vDimm, changed to CAS 3 and 2t and cranked the FSB . . .

Oooh didn't expect that! Corsair PC4000 in disguise running at 2.6vDimm, strange, even though it passed many hours of Memtest it errors out in one hour using Prime Blend or Large-FFTs, it's not the chip or the mobo because when I install actual PC4000 (OCZ/Muskin, will discuss later) the Blend test doesn't fail, think I'm safe to assume there is something with the Corsair running so fast, however I always thought Memtest picked up errors like that?

I also have no knowldge or experience with these memory settings?

Row refresh cyc time (Trfc)
Read-to-write time (Trwt)
Write Recovery time (Twr)

Anybody care to comment further about these IC's or PCB?

Thanks again!

you would never get them running stable at 2-3-3-6 1T with only 2.6v through them

Oh I see. Well as far as I can tell they are rock solid stable at that speed, in fact they are up to 217MHz 2-3-3-8 1t still using 2.6vDimm?

Hoping someone is familiar with the actual Infineon BE-5 memory chips? I'm not!

In the meantime I will just keep slowly testing . . .

Any recommendations of late or the last AGP/DDR 400 mother board and CPU combo's?

Oi get your own thread!

Back on the topic of DDR many thanks for all the helpful replies, I pretty much drifted through the DDR days using CRUCIAL Vanilla or Ballistix so missed out on all the exciting PCB talk!
