Can't seem to overclock FSB and Clock speed on 2500+ without getting instabilites.

[Hexedit]

I have an 8rda+ rev 1.1, barton 2500+ AQXDA 0319, and 1 gig of pc3200 Twinmos w/ CH5s.

My problem is that when I overclock my system to lets say 210 mhz FSB and 2310 mhz (11x multiplier), my computer will run through memtest through 100 passes of test 5 without a problem; however, when I run prime95 I'll get through the 1024k FFT, 8K FFT, and 10K FFT tests, but I'll always crash on the 896K FFT tests. This isn't some random occurence, it has happened on 3 different CPUs, 2 sets of ram (pc3200 and pc3700), and 3 different BIOSes so far (3712, 3609, 3507). The only time I can get my computer stable is when I'm not overclocking my CPU.

If anyone can help it'll be a miracle because I've tried almost everything and nothing seems to work.

Vdimm - 2.77
VCore - 1.85
VDD - 1.77

overclocking 1 gig of memory is not too easy, especially in dual channel. try putting them in single channel and see if prime passes. also, the 8rda+ rev 1.1 doesn't have vdd adjustment (it has options in the bios, but it doesn't work...stays at ~1.58-6)...do you have a mod to get the 1.77v? you can also lower the multiplier and up the fsb to see the limits of your mb and ram first, then do the reverse to find the cpu's limit....then go with a combination of the 2. good luck.

try raising your Vdd up to 1.80 - 1.85
