Hi guys,

I need some help overclocking a FX 8320, I;ve never overclocked before and non of the info online is helping most is going over my head, too techi for me to understand, at the moment everything is on auto and im overclocking at 4ghz using the only the cpu ratio setting
 
thats pretty much all you need for a first attempt.

my advice, write down every combo of timings/voltages at every step so you know where to fall back to if it starts getting unstable or such.

the way i did it was:
inc multiplier 1 division [0.5 on my board iirc]
boot and run prime for 10 minutes
restart and repeat

then when i started hitting core errors on prime, stopped the multiplier increases and started increasing voltage in the same way until it was stable again.

just keep going with this method until a voltage increase gives temps that are too high, then revert back to the last stable setting with decent temps and run a longer prime test to make sure it really is stable.

if you take your time, don't rush and write everything down its not as hard as you'd think. time consuming though. it'll not be a professional clock, and there's plenty of guides for the more advanced stuff. but baby steps one at a time.

do i need to change the cpu voltage or should i leave that on auto ?

its the offset voltage, there are other settings you need to consider, check the guides/yt vids. i recall there was a decent one covered all the stuff you want to turn off/change on your board [i'm using the gen 1 sabertooth].

i'll confess to noticing voltage increases during my process before i'd actually changed anything relating to voltage, although that could simply be monitoring software.

i'm like you to some extent made, even after managing 4.3 stable i'm still not as clued up as i like to be about this sort of thing.
 
Always put voltage on manual when clocking.

How far did this take you:

You have plenty of safe overclocking room. I would let it not go past 60 degrees under normal use for extended periods of time. This is not 60 degrees under prime but under a few hours of gaming, if that's what you do with your rig.

1.45 would be enough voltage for you to hit a substantial overclock, while keeping sensible temps i would imagine. Turn off turbo and auto voltage though. Auto usually overestimates the voltage you need and turbo may clock your CPU speed past stable limits after you set an overclock. I use to run my 8150 set up at 1.5V 24/7 without issue, though that chip was golden (bash BD all you want but this specific chip beat the vast majority of the PDs i have clocked and i have clocked many!).

If you are after a modest quick clock, try x22 multiplier at 1.4V. If that is stable, drop the voltage and see how low you can go before the chip disagrees. If it is not stable, bump the voltage. I have seen some people get away with 1.35 for x22 and some needing 1.44, its mostly chip and cooling dependent. Pray to the silicon god!

If you want to hit higher clocks and are willing to spend time clocking, i would start off with the bus rather than multiplier. Turn memory down to its lowest multiplier to minimize memory errors while finding your clock. Turn turbo, CnQ and simialr features off and set voltage to manual. Then start upping the bus bit by bit, upping voltage when you need it and stability testing using gaming if your a gamer. It would surprise me to see a 8320, which is sufficiently cooled, to not be able to hit 4.7Ghz at the least by using this method. When the bus clocking is done, you can turn emmory multiplier up to the nearest frequency it is rated at. If you start to get memory errors, send a voltage bump tot he CPU/nb or turn the memory down a notch to see if it helps. After that is all done and you still want more clocks, play with the multiplier adjusting bus up and down, all the best clocks on fx chips are usually done by changing both multi and bus whether it is going up or going down.

I forgot about that, I managed to getting 4.5Ghz on 1.32v, 32c o normal use upto 61c running prime95 for 1hr.
 
I've managed to OC to 4.8ghz (1.39v) so far but temps go upto 70c on stress test, is there a way to reduce the temp ?
will increasing the voltage help ?
 
voltage is what causes the temperature bumps, the only ways to reduce it is less voltage or better cooling. your sig says you've got a custom loop so depending on what that is there may not be much room there.

you could feasably get away with it, prime is a worst case scenario kind of benchmark to see how it handles, if your not getting that kind of temps in games then you could get away with it, but if you do anything that loads up the cpu like prime does [rendering for example] you'll maybe need to consider dialling it back a bit
 
Everything else seams ok it just with prime95 the temps go up, Im thinking of dropping down to 4.6Ghz and reducing the voltage.
 
Prime95 is gonna stress the system more than you'll ever actually do in the real world. If you can knock the clock speed down to something you're happy with thats cool, otherwise you can just try to see how low the voltage will go without errors.

I'd say, if theres a hot day, leave the windows closed and have a hour or two gaming or whatever you do and if it seems fine then i'd leave it there.
 
Thanks, I've clocked it down to 4.5Ghz, Im getting the best results at this, the pc stays cooler even with prime95 no errors, and it feels stable.
I can overclock above 4.8ghz but the temp with prime hits 70c I could mess about with it but I dont see the point, It will only be a bragging right and a few 100Mhz, the temps will still be higher than what im getting with my currant overclock.
