Today I brought Ice back up to 4 G and beyond for some more runs at Super Pi and 3DMark06.
Cracked off several runs at 4043 and below. I also gave the 1333 NB strap a few tries but the marks were lower so I moved on.
Having a real time trying to run the RAM at 1000. Any use of a divider beside 1:1 would lock up the board and require a pop of the battery and so forth.
Many hours later I was able to determine that the RAM will likely run at 100, but the BIOS will not support it.
I then turned my attentions to RAM timings as there seemed to be no way to increase my scores. The Abit does not seem to like a lower multi either. CPU-Z reports it as x 9 regardless.
In the 1333 strap CPU-Z does not know what to make of the RAM timings and memset does not work either--so all the tweaking was done in the 1066 strap.
I turned the RAM volts up from 2.45 to 2.55 and this definitely stabilized boots into XP past 4005mhz. Not sure about the long term effects of the overvolting to the RAM.
While trying for the fastest Super Pi times I tried small adjustments to the timings with memset. From 4 5 4 6 which is how I have it set in BIOS to assure botting into XP I tweaked it to 4 4 4 5, 4 5 4 5, 4 3 4 6. and 5 5 5 7. Changing the first value resulted in an immediate blackscreen. I was surprised to find that the timings seemed to have little correalation with the Super Pi times. But they did have some effect on stability.
At anything much above 3800 Orthos is a no go--so I am gauging stability by whether or not I could make it through 3DMark06 without crashing. The best timings for that seem to be 4 5 4 6.
Right now I am seeing how well the rig will Fold at 3979. So far it is going along without a hiccup. Could very well be that the stress of Folding is not great enough to create any issues...we will see.
Currently I have the Voltage at max for everything. 1.675 Core 2.0 MCH 2,55 RAM.
Going to carefully watch how the rig handles this for the next few hours.
Here's some screenshots of my efforts from today.
I am especially pleased with the mid twelves in Super Pi.
And breaking into 9103 with 3DMark06 is kinda nice... even though it's only anoth 6 points lol.
Here's three runs at 4005mhz with different RAM timings all yielding the same Super Pi time.
