😕 I'm not drilling oil, it's a computer!
😉 I flashed the BIOS last night and looped benchmarks, so I'm running a different overclock than when I posted above.
This is what I have now (not everything, just what's relevent):
Chaintech VNF3-250
3200+ CG stepping @ 240x10.0, 1.5v (3x HT)
Tt Venus 7+
cheap PC3200 memory @ DDR400 2.5-4-4-10 (it works @ 2.5-3-3-8, changing it later today)
a 240GB RAID
a 250GB SATA drive
BFG 6800GT OC @ 400/1100
350W A+GPB PSU
lowering the HT multiplier from 4x to 3x (720MHz instead of 800MHz @ 200MHz) let me raise the FSB to 240MHz and get the memory back up to DDR400. HT @ 4x240 wasn't stable on this board and I already added a fan to the chipset.
🙁 It's a tradeoff because HT @ 4x (220x11.0) only let me have memory running at 366MHz (440MHz didn't work with this cheap memory, even by raising voltage and changing timings) but let me have a higher stable HT frequency of 880MHz. IOW it runs faster at 240x10.0 overall than 220x11.0, despite the slightly slower clock speed.
The NF3U chipsets are supposed to have support for HT @ 1000MHz, so maybe I'll upgrade eventually. 4x240 and 4x250 would then work with memory at DDR400/DDR415.
