9850 cores 3,4 fail in prime 95

post #1 of 3
Thread Starter 
I currently running it at:

bus= 228
mult= 15
CPU volt= 1.6
NB volt= 1.6
NB mult=10
HT=2.0ghz
ACC=4% all cores
MEM=902mhz (or close to)
timings= 5-5-5-15-2T

if i do anything other then changed timings and bump mult to 16 and voltages to 1.48 for both NB/CPU and put ACC at 4% 3,4 cores ALWAYS fail in prime 95. If i try to up the ACC on these, no boot.

I would try dropping the multiplier down and using a higher bus... it might be a BE, but i bet it'll play more friendly with a 14x multi

If that doesn't work, you might be hitting your maximum OC... 9850s seem to be capping off at 3.2-3.4GHz for most people

It died today :-/ R.I.P. AMD 9850BE

hopefully AMD will RMA it, if not i have a reason to buy a 9950 and hope i get better OC results
