Very strange indeed, just like mine. I think the mem controllers on these are very sensitive to timings, so do a tweak attack with every config you can think of in your DRAM timings and bus mulitipliers. Mine right now is doing 2.9Ghz with 1.45V, but will boot up at like stock voltages. Even at 1.45V it craps out dual prime in 2hrs. I doubt it's my temps, because my IHS is off, and my temps highest will go to 50C, but that's at 1.6V. Right now at load temps won't go over 38C. What kind of memory are you using?Quote:

I'll post up pics in a bit. O, and I'm trying my DRAM voltage very low right now, I'm at 2.53 right now, and it's priming right now. Crossin my fingers. But evidently "most" UCCC chips like low volts. try it out.Quote:

Lucky I got a '904' then! :woot:Quote:

Your right about UCCC liking low voltage, but that is a strange problem with your chip. I have used UCCC and Ballistix (both 2gb kits). My UCCC OC didn't change with this chip, but my Ballistix does near 300mhz, but hates tight timings, so I have to keep them at 3-3-3-8 at all times, with loose subtimings. Try setting trfc = 18, mal/rp = auto/auto, dynamic idle counter = disable. See if that helps. If not, you may just have bad luck with CPUs.
Hi.
Can anyone tell me where to find the batch number? And what does the batch tell you?
Thanks
3rd line on the chip.
There are two variations for the 5th, 6th and 7th digit, and the one like this 1434904C60XXX is said to be better.
What is CCBBE like in comparison. If my memory only runs 237mhz now as opposed to 261mhz (next divider up) on my CCBWE chip, might I be able to get my sticks running at 261mhz with a CCBBE chip?Quote:

if someone does please contact me (i'm in the US for 3 more weeks)
because tankguys don't have CCBBE anymore :/
So there is better performance to be had by having the cpu speed at its max, and ram at the tightest timings possible and max ram speed at those tight timings?Quote:

Yeh, it's what I did to make up for it.Quote:

Thanks.
exactly, i've seen a couple tests on forums and benching sites that follow this same theory, and back it up with some stats. most also show that the higher the cpu frequency, the higher the margin in performance between tight timings and high mem frequency. this being the only one i could think of off the top of my head Tight Timings vs. High FrequencyQuote:

BB, B1, BW etc are NOT memory controller revs, AM2 has BY and BV so far which has been on 939 DDR1 chips, when we all know for a fact that AM2 has a brand new mem controller
but remember that AM2 is a different Revision of the A64 platform. So, with all due respect, you can have the same memory controller revision within a new platform that is entirely dissimilar.

Sorry of being offtopic at the moment, but who s updating the OC database ?
I ve submitted my screenshots -3H Prime large ffts a couple of days ago.
Could you point me to the " in charge " person ?
THX ;)
i tried what you said with no luck....this is annoying.Quote:

2.75 @ 1.425. 39c load
***WTF IS THIS***
2.8 @ 1.5v. 41c load
2.85 @ 1.55v. 45c load
all with at least 1.5 hours of prime.
@repo... are you saying BB, B1 and BW are not memory controller revisions? or they are not AM2 memory controller revisions?
you either got a dud, or some setting is or other hardware is holding you back. both CCBBE's i had did 2880 on 1.375vQuote:
