Opteron 148 OCing
Okay, so my dad assembled an SLI-DR + Opteron 148 rig back when those were the kings of OCing, and I've never really gotten around to overclocking it. Today I decided to really go for the gusto, and start OCing.
Started at 250MHz bus with a 5/6 divider, coming out to 196MHz memory and a 2000MHz even LDT. Well, I originally had the CPU at stock voltage with a 10x multi to get 2.5GHz. That's pretty cool, I reckoned, but the BIOS was out of date, so I flashed it and loaded defaults. I set the divider and bus options back, but forgot to lower the multi from 11 to 10x, and I didn't even really think about it.
Computer booted into windows and I checked CPUz to make sure all my clock settings were correct, and I noticed the CPU at 2.75GHz.. On stock voltage, and the computer was responding admirably.
I've now been running Prime95 on it for a half hour, and it's chugging like a champ at 44C/111F core, 45C/113F surface on full load.. 2.75GHz, 111F, stock voltage! This chip is crazy! I haven't overclocked in SO FRIGGIN LONG and this chip is a breeze to work with.
I wish he had something better than PC3500.. Gonna see if I can go for the magical 3GHz with a 300MHz bus. Air cooling, chaps. Wish me luck.

My 148 did 2.8 at default volts, but needed 1.55 to get up to 2.9 stable on air cooling. That one seems to scale quite well with the vcore. Is that on a stock AMD HSF?
