Overclocking help - AMD w/locked multiplier

[Mocs123]

I would like to AMD Phenom II B35 (Unlocked Athlon II 435) my processor a little bit more but I can’t seem to keep it stable. It runs cool (~40*C)even under load so I don’t think it is a heat issue.

Currently I have

AMD Phenom II B35 (Athlon II x3 435 with unlocked 4th core)
1.425 V
Multiplier x 14.5 (locked)
HT ref clock 210

Cooler Master Hyper 212 Cooling

Corsair 1066 Memory

Nvidia GTX460

Gigabyte 770 Chipset mobo

I have built several computers but I have never overclocked any of them so I am a complete novice at that. Any suggestions?

Thanks,

Brad

drop your ram to DDR2 533
drop your Hypertransport(HTT) clock/multiplier to to 5x (1Ghz)
then raise the HT ref clock up 10-15mhz steps stress testing between them until it fails you can drop back 5mhz and test again to see if it passes or raise the cpu voltage til it passes.

typically i set my voltage to 1.45 or 1.5v(in your case i'd go 1.5v since your temps are very low). then i raise the HT ref clock 10-15 mhz til it fails to boot then i either drop the ref clock 5 mhz til it passes or raise the cpu voltage til i either reach the max safe voltage (1.55v) or it becomes stable. if its still unstable at 1.55v then i begin to drop the ref clock in 5mhz steps til it passes 10-15 passes on IBT. once i've done that i start lowering the cpu voltage in small steps til it fails then raise it back up til it passes again.

after all that change your ram multiplier til your as clock to your reference clock of DDR2 1066 then raise the HTT multiplier til your as clock to 2Ghz as possible(note you can go over 2Ghz but a lot of boards stop posting at 2.4Ghz.

You can also lower your RAM timings. The TRAS is the first thing Id adjust. This value goes up to 18 max so adjust it a little at a time til you hit stability. After that, adjust the TRCD and TRP. You can raise the CAS latency too. Mine was stock at 4-4-4-15 and I ended up with 5-5-5-18.

Your unlocked core might be cause stability issues as well. 210 is a pretty low FSB so if you cant get any higher than that, try disabling the 4th core and try it as an X3.

OK I have my fsb up to 225 and run stable on prime 95 for 8 hours (43*C max temp). I have my HTT multiplier back to 2Ghz, but how do I get my Ram back to 1066? I have multipliers of x4 or x5.33. I runs OK with the ram at x4 (but at ~900 mHz), if I try and bump it up to x5.33 (~1200 mHz) it isn't stable. Is there any other way to get it back to 1066? Is it even that big of a deal?

BTW: I use this computer for games, office, ms project, internet, I don't do video encoding or anything like that.

Thanks for your help!
