***official amd 83x0 overclocking thread***

Could someone help me with overclocking my 8320????
Ive never overclocked and most of the above is going over my head, some simple instructions will be useful.
 
After asking for help on here and help from Avenged7Fold I managed to get a very stable 4.5Ghz overclock on my Fx 8320

Any reason why the 9370 and 9590 say the maximum voltage is 1.65v and the max voltage of the 8320 is 1.41? I presume it's due to the TDP?

Theres no difference between chips, the 9590 etc are just binned so they can get to 5Ghz with a lower voltage. The actual max voltage any of them can take is exactly the same. I believe someone on here emailed AMD and actually asked and they said the max voltage is 1.6 odd for the 8350.

HOWEVER, I really wouldn't go past 1.5v for any normal cooling solution. Theres a reason when you type in 1.5v into asus boards that the font turns red :D

Can you give me your exact settings (bar memory) which you used to get 5.1GHz please? :)

I can't tell you the exact settings at the moment as my pc is out of action due to a gpu problem and of course FX chips don't have any onboard graphics.
EDIT: found them on the corsair domination competition :D (also just realised that it was 5.15Ghz not 5.12... changed my sig now :D)

CPU: 5.15Ghz (Bus: 270Mhz; Multiplier: 19x) @ 1.5v
North Bridge: 2700Mhz
RAM Frequency: 2160Mhz; 11-11-11-27-1T Latencies @ 1.65v
LLC: Ultra High; All current capabilities set to 130%
All energy saving modes set to disabled

Just so you know, this was NOT prime stable for me and thermally wasn't great, but allowed me to do all the necessary stuff for the competition. I could, however, play bf4 etc so that was stable enough for me :D

Also, should really should tighten up my ram settings :(

Would you say the bus clocking is key to get the stability at that voltage vs the multiplier?

It certainly worked for me. Could get a very stable OC with just multi at 4.8 but wouldn't go past there/required too much voltage.

The gains on cinebench are also quite large - went from [email protected] using multi to [email protected] using mixture of multi and bus. Ok not a massive difference (only 6%) but considering it needed slightly fewer volts, it worked out well for me.

Im thinking Im going to back down my OC to 4.82 again as that only required 1.42v (and I think I may be able to lower it a bit more) as opposed to 1.5. Not convinced the speed is worth the extra heat.

cwgk91 your a star, thank you

I can't for the life of me figure out how people with the same clock speed are getting better results than me on Cinebench, even when my CPU is higher.

One think I would say is that the RAM and timings I used made a big difference. When I used 2400MHz sticks (2 x 4 GB) with tight timings vs 2133 MHz sticks with modest timings, I got 30-40 more points on cinebench R15. Best I got was 832 I think at 5.15GHz
