Prime95 Temp Max I forgot but its low, maybe 55 tops
Ok in my trials, I've gotten:
CPU: 445 x 9 = 4.0Ghz
DRAM: 890Mhz
MCH Freq: 400Mhz
Something multiplier: 2.00D
CPU VCore: 1.26875 (under auto this was 1.344 resulting in 80+ temps)
Ram Timing: 5-5-5-15
Max Temp under Prime95 for 4 hours: 71, 67, 65, 65
CPU: 356 x 9 = 3.2Ghz
DRAM: 1138Mhz
MCH Freq: 333Mhz
Something multiplier: 3.20C
CPU VCore: Auto
DRAM: 2.1V
Ram Timing: 5-5-5-15
Max Temp under Prime95 for 4 hours: 65, 61, 59, 59
It seems I can push the CPU to a fine place, but the ram is supposed to run at 1100mhz, and it tops out at 1138mhz, runs stock at 1066? What ratio is the best? Should I get different ram? Whats the deal with ram timing? I couldn't boot with any changes to timing that Ive made so far. Will I notice a difference between the system @ 4.0Ghz, 890Mhz or 3.2Ghz, 1138Mhz? I don't particularly understand the MCH strap either. How do I determine what I want that to run at, as articles have told me all of them, however stability is hard to come by without changing a ton of options, and then you don't know if you are preventing errors or causing them. Once I get some decent settings I'd like to run a 12 hour or 24 hour prime 95 and a 3dmark06 to compare, but I cant seem to get a better OC than the 2 above. I've never overclocked before this attempt which started about 2 days ago. Thank you kindly.
Suggesting 1:1 DRAM:FSB is best, should I just set to 4.0Ghz/890Mhz and slowly increase FSB, bringing RAM to a better speed @ cost of further CPU overclock?
Assuming Ratio is not as important as Ram speed, should I continue to work on the RAM highpoint (3.2Ghz/1138Mhz) by adjusting various voltages? I think the ratio is 3:2 in this setting, and I've already failed Prime95 within 4 hours beyond this setting with increases to DRAM volts and MCH something only increasing the time before Prime95 Fail.
Is there another perspective I've completely missed?
