Phenom II x4 925 3.4GHz With 1.385v (c2 Edition)

post #1 of 4
Thread Starter 
WOOT guys ... today i have reached 3.4GHz from stock 2.8GHz with only 1 time increasement in voltages from 1.375 to 1.385 that minimal increase gived me 600MHz overclocking , 2.43GHz on Northbridge with 1.285 and 2187 HT link.. and my ram stays on 1620MHz with 9-9-9-24-2T 1.65v...
any more ideas to reach 3.6-3.8 (as peoples said 3.8 barrier for c2) ?

by the way my temps are good ... 3 hour prime and i got 50'C on core and 57'C cpu temp...
and 925 limit is 71'C (and i think this 71 is for core temp...)

Keep going,

Drop your FSB: DRAM ratio, and you're getting close to dropping your HT link multi. Keep pushing your FSB, and add voltage only to your CPU and CPUNB. Reaching 3.6 should be no problem with your chip there.


Yeah, I know my chips stable ceiling is at about 3.87Ghz, but I run at 3.6 24/7. I had it up to 4Ghz+, which is pretty rare for a C2 (945 though).

Push your FSB to reach 3.6GHz then set your vCore to 1.45v. It's highly unlikely that you'll reach 3.8GHz with C2 stepping.

See my validation link, I've disabled my SLi because of the CPU bottleneck. If I see any bottleneck my nerves automatically go haywire.
