Well, guys, I'm still at it, but as of this morning this setup:
HTT: 275
Mult: 10x
vcore: 1.500v
DDR2: 400 MHz (1:2 Divider) @ 4-4-4-8 1T
HT mult: 3x
PCIe: 100 MHz
has about 15 hours stable running two instances of SP2004 on blend. Obviously, I'm a little disappointed in my memory. I list my maxes for those who don't remember:
HTT - 318 MHz
CPU - 2.80 GHz @ 1.500v & 2.85 @ 1.550v
Memory - 330 MHz (on HTT) @ 5-5-5-15 1T
Problem is that during the consolidate phase I can't even POST unless I drop down to a 1:2 divider (Yes, I followed Zebo's guide - dropped the CPU multiplier down to 6x, set a 1:1 divider and started pumping up the HTT until I failed memtest86+ - which never happened - at 330 MHz, it didn't make any sense to go further).
Now, I think I've got this figured out - I think it's because my board will only give a max of 1.95v to my memory (stock is 1.9v). As you can see in the above setup, I've tightened some timings to try to compensate for the low bandwidth (550 MHz in the above setup).
Now, I'm not so arrogant as to sneeze at 2.75 GHz, but I'd really like to have my memory do a little better - I had higher expectations considering the results I got while trying to isolate the memory. My system cooling has been amazing thus far, and while I know that the weakest link always holds you back in overclocking... *grumble*
While I'm complaining (puts on flamecoat...) it'd be nice if Asus's next BIOS revision allowed higher vcore and memory voltage settings, allowed for finer (0.5) CPU multiplier adjustmentts, and offered more than the current set of memory dividers (1:1, 5:6, 2:3, 1:2). I know AM2 is still a fairly new socket (what has it been - 3 or 4 months?), and I'm not saying 'Asus !$ t37 suX0r$!' - I just hope that another revision will open some more doors to overclockers because I feel this board has held my memory back.
So, in addition to taking constructive criticisms on all this, I'd like to know how feasible it would be for me to do the following - Since I'm stuck at a 1:2 divider, could I drop the multiplier (say to 9x) and raise the HTT (say to 305) to compensate and hit the same overclock with a higher memory bandwidth (610)?
