I built a nice system with the help of these forums about two years ago. A few days ago I upgraded my cpu from a 3200+ Venice core to an Opteron 165. To my surprise it booted up right away with what I believe were simply the exact same BIOS settings I had for my old chip, which resulted in a 400mhz overclock to 2.2ghz. I'm somewhat experienced in overclocking. I'm at the point right now where I'm trying to make some minor adjustments to coax some more out of the chip and I'm just baffled. It seems to be common knowledge that loosening up the timings on your ram will allow it to run at higher frequencies. So, I increased my CAS latency to 2.5 and eventually 3 (from 2) and it won't boot. Luckily I finally realized what CMOS Reloaded was for and managed to save a bootable setting before I got into this mess. If the only change I make is to increase the CAS latency, she wont boot. What's more is that I can decrease it to 1.5 and it seems to be pretty stable so far. Made it through 3dMark03 w/o a problem.
So it runs at 1.5 or 2, but nothing higher. I don't get it. This was supposed to be my next step to get more out of my OC! Mobo is a DFI Lan Party Ultra nforce 4. The ram is 2x512 Patriot pdc1g3200+xblk. Any help appreciated .
