opty 148 stuck at 2.97?

post #1 of 13
Thread Starter 
ok, 2.97 stable as a rock....



why is it so hard to get 30 extra MHz without ridiculous voltages? ive tested this thing at 1.648 @ 273 1:1 and it keeps dying at about 45 minutes of SP2004.

oh yea, my load temps are ~41C or so and my mem can run stable @ 280 MHz too. any suggestions?

I've encountered the same wall at 273 fsb. Went up to 1.7 volts and it was still not stable, just wanted to see if I could get 3003mhz stable. I'm guessing thats the limit of our cpu with CAB2E stepping unless you go extreme voltage.

I backed down to 264x11 2904mhz 1.6 volts and have been stable for a month now.

Have you tried to find a sweet spot in the vcore area of low to mid 1.5 range? Many OCers have posted those result with validated OCs. That being said it was far more the scenario w/2x512s though! I would speculate the 2xG was a heaver load on the CPU/RAM controler and part of the equasion.

ive tried all voltages from 1.5, 1.52, 1.55, and now at 1.58

i finally was stable around 1.58. where can i find this database? im almost considering a 1gb of TCCD's for higher clocks, but then again id be sacrificing 1gb of mem for less then 100 MHz. not worth it IMO.

From my experience, I have found that I can squeeze just a little bit more out of a cpu if i use a in windows program to overclock the last little bit. I suggest clockgen, but you can choose which one you want to use.

ive used clockgen to test the stability of my mem, but hypothetically if it works in windows, couldnt i use it in the BIOS?

i might try and raise to 273 FSB and run after i test 271.

im so frickin close to 3.0 i can taste it, lol.

computers don't always work hypotheticly, they are crazy creatures. you can't be sure until you've tried it. I'd try out clockgen or sys tool and just see if it will work.

Another Idea is to play around with your ram. change up your dividers and timmings to achieve that victory of 3.0.
you pretty much have to play with everything you can just to get it there.

Try dropping the multiplyer, raising the clock and running a divider on the RAM

I think the 11x multiplyer might be the problem, probably stressing the CPU too much

ive already tried 300 x 100 with 166/180 divider and still fails. would a lower multiplier enable me to use a lower voltage? i wanna try and keep it under 1.6v if possible.

also, i thought a lower fsb and higher multiplier is faster (esp for benching). is this true?
