It seems this memory is supposed to run at 4 4 4 15 at 400 fsb on my P5B-E. It won't and it won't on my DS3 either
I have to run at
CAS 5
RAS to CAS 6
RAS Precharge 6
cycle time 18
for my system to be orthos stable
I'm running E6400's
My Corsair PC6400C4 runs fine at 4 4 4 12 on either board
I've tried from 1.9 to 2.1 volts
What's up with this??
I think the Corsair is using Promos chips

rev 2 is also using proMOS.
I can do over 1000mhz cas5 on the AB9 pro (2.2v), but max stable on the p5b was only 960 on 5-6-6-18.
If you can only run that timings @800mhz then you should RMA your RAM.
Just ask RyderOCZ ;), he probably knows what to do.

It pays to pay attention.
I've now posted over on OCZ's support forum

Set the Write to Precharge to 11 or 12.
OCZ Rev 2 is using PSC, not Promos.

PSC, did they always use PSC, or only the newer batch?
Everyone was talking rev 2 had Promos :confused:

No, they didn't always use PSC, but they do now :)
how do these sticks do with N650i chipset??
and how are PSC IC's compared to Promos, do they really clock that much worse

the PSC chips are performing very well. Do not cry!
