Athlon II X2 255 @ 220 Fsb Wall

post #1 of 19
Thread Starter 
Done my research and googling.

A770E3 biostar mobo
8gb ddr3 1333
CPU in title
458w psu
Gt 430 1 gb
250gb seagate

I either post into a "too many cold reset due bios post" error (verbatim) or a checksum error in which case my bios settings are reset. So I'm stuck. I wouldn't be posting if I thought I could find an answer without doing so. Any help would be greatly appreciated. Even any insight into these errors would be great!

Thanks,
Siggy

That's a failed overclock-you need to lower RAM speed,bump up voltages etc.

also keep the HT speed close 2000, 2200 is too high for it
post #4 of 19
these X2 are great little oc'ers for their price, you should easily be able to get higher.
In my HTPC I have the X2 240 at a comfortable 3.5Ghz

250 fsb x 14 @ 1.4v
HT at 2000
and that other Hyper thingy I'm pretty sure was 2600
didn't need to play with any other voltages
oh and the ram, I had to downclock it from 1600 to 1333 with tighter timings too.

Give those settings a crack

Hey! Thanks for the snappy replies! Should I boot all the way into windows and then shutdown when checking the limits of JUST my fsb, or wait till the post beep and then kill it. I've turned everything down in order to check my fsb limits for my mobo, but I'm not quite sure on this little detail.

Thanks,
Siggy

use cpuid to verify clock speeds, cpu/fsb/ht/ram
and hwmonitor to check temps and voltages

Okay so I slowed my ram down to 800mhz, clocked the fsb up to 235, but dropped the multiplier down to 15x instead of 15.5x. I kept my voltages the same, (stock) and was able to post and boot into windows. So now I'm priming away for the next half hour or so checking temps and then I'll try bumping it up a tad. So I'm at 3.5 MHz @ 235.

With my fsb what it is, my memory is really at 470MHz*2=940 instead of 800 which is great and all, but how much of a performance hit is it from 1333 down to 940?

At the moment I'm at a stable 45c under 100% load, so not terrible, not beautiful either.

Yes, thanks jjefrxx,

I've been rocking speedfan, (little weird) prime 95, and cpuz for a while now, but I've never heard of hwmoniter.

I'll have to give it a go.

What would the timings be on your memory? Try bumping it up around 1066, I didn't notice any speed difference at 1066 vs 1333 vs ~1432.

Stock they're 9 cas latency. I didn't recognize any of the other settings in the bios for memory timings so I just set the cas latency to 9, and dropped the speed to 800 MHz.
