Hi everyone, I'm trying to squeeze a couple hundred more MHz out of my Opteron 170 I got the other day. Here's my setup so far:
Opty 170 CCBWE 0551 UPMW
Abit AN8-SLI - BIOS 20
2GB G. Skill PC3200
Koolance Exos watercooling
Enermax Whisper II 535W
I run 2.4 GHz at stock volts (1.35) no problem, 32C idle and 39C under load. System boots at 2.7 GHz but is not Prime95 stable, even when I put vcore up to 1.5. Temps are around 50C when it craps out.
I'm running a 5:6 divider (DDR333), from testing my RAM at low multis I'm able to tell it tops out around 230 MHz on stock timings (2.5-3-3-6). So when my HTT is 270 this RAM is running at 225... but I still think I'm pushing it a little.
So question 1: Is it a good idea to loosen the timings up to something like 3-3-3-8 at 225MHz or am I going to suffer too big of a performance hit from that?
And question 2: I see a lot of other voltage adjustments in the BIOS (DDR, NF4, HTT). Just from Googling around I don't see too many other OCers out these messing with these settings (except DDRv). How many of you use them? I'm leaving them all at stock settings right now, is that a mistake?
