Phenom 965 BE nearly stable at 4.2ghz whats next?

post #1 of 12
Thread Starter 
I am pretty new at OC this is my first attempt with adjusting voltage. Right now I have My 965 at 4.2ghz @ 1.48v. I tried it at 1.47 and it crashed 30secs into Prime95, ran at 1.49v in Prime for a good ten mins and never went over 57C i stepped it down to 1.48 and i get worker 3 and 4 errors in prime 95 after a few minutes. I have done a little bit of research and i hear that i need to up the NB next to get this stable is that correct and what would be the best way to do that how small off steps should i take. right now NB is at 2000mhz. here is my rig specs



Phenom II 965 BE
Msi 870A-G46
8gb Gskill Ripsaw RAM @ 1600mhz
Gtx 560ti @ 925mhz
ssd and hard drive
antec 550 psu ( corsair 750w in the mail )
cheap best buy heatsink ( corsair H100i in the mail)

not so sure about that mobo . . .

4.2 looks cool. it should be enough for the 560ti.

What are your temps?

Your mobo will blow up and you will be sad though.

I do not see my exact Mobo on that list.

My temps are idle 30-33C under full load never over 57C. I just really want to get this stable at 4.2ghz just to say i did. If the board blows then that gives me an excuse to get a new one tongue.gif but what would be my next step if you were to try and get this stable?

What's next, or so I'd recommend, is to return to stock and look for a motherboard replacement, pronto!

This 870A (or direct variants, they all share the same VRM design) should be on that list several times. By the data I have collected and placed onto that chart, the MSI 870 lineup is the most VRM failure-prone board lineup in history.

 

Please, do yourself a favour and don't risk a fire.

don't forget when you do OC, when the time comes, the CPU/NB should be overclocked! Provides big performance gains for the Phenom II architecture.

FIRE?? i guess i underestimated what you meant by blow up. is there anyway to maybe add heat sinks to the VRM for the mean time? I have been running stock volts at 1.43 and getting a stable overclock at 3.9ghz is that safe? not really excited about going all the way back to stock 3.4 frown.gif also any mobo recommendations? what makes a good overclocking board?

Is the procedure pretty much the same as overclocking the CPU?
