AMD FX-8320

GavinG · 13 Aug 2013 at 19:35

Hi i would appreciate some help on this if possible.

I wish to overclock my FX-8320 3.5Ghz (4Ghz Boost) to roughly 4.2 or 4.3 depending on temperatures. Hopefully this can be done by just using the multiplier as i don't really want to go near voltages? I need to know exactly what things need turned off and what exactly i should be changing to achieve the desired overclock.

My mother board is a Gigabyte 990FXA-UD3 AMD 990FX (Socket AM3+) DDR3 Motherboard. (The Newer Bios version which doesn't look like a normal blue screen bios)

I am currently using a Thermalright True Spirit 90 CPU Cooler with a Zalman Z9 case with an extra 2 120mm fans so plenty of through air.

Idle i sit at 7C-10C and full load around 45C.

Here are a couple of screen prints on full load.

If you need anything else please let me know.

Sorry if im being a newb but this is all new.

lol It's a heat wave over here in Ireland don't you know!

Do i have to turn anything off teppic?

Is this it? Bus Speed 5200 MT/s

I take it i should stay well clear of EasyTune 6?

Ok went into bios there and got these?

HT Frequency Max 3200Ghz
Clock Ratio goes up to 39.5

GavinG · 13 Aug 2013 at 21:28

Yep got it BCUK Clock Control was at 200 GHz and can go up to 500 GHz

Ok folks here is what i have done, the only thing i have changed in the bios is the multiplier to 21 which is 4.2?

I have ran Prime95 for the past 40 minutes or so using the torture test (small FTTs) and here is my stats so far. Are these any good? Should i change anything else, i don't want to push it.

The following things move about but these are the ranges according to CPU-Z:

Core Voltage Min 1.236 Max 1.356
Core Speed Min 2913 Max 4219
Multiplier Min 14.5 Max 21

That figure goes up and down between 2913 and 4219 i assumed this was for all 8 cores? I can confirm on task manager that all 8 cores at at 100% usage, would this movement up and down be something to do with the power save thing?

I have looked for something that shows the speed of all cores but can't find anything

I have reduced the multiplier to 20.5 so 4.1GHz for the time being will try again 2moro.

Thanks for you help so far

It's rev 3, should overclockers have sent rev 4 instead of 3?!
Also that fluctuation on core speed was happening before I changed multiplier ie when it was stock.

Also temperatures are not jumping about they seem constant, gradual and consistant with no spikes or drops, the temps shown on HW monitor above didn't get any higher than that and I now know amd temps are not the most accurate, but surely HW monitor would have picked up jumps and drops in temperature even if they might have been slightly wrong?

This is a vid of what im getting, this is all reset to stock settings, but im getting the same type of movement if i overclock

Posted a note up there, fingers crossed, thanks teppic

GavinG · 14 Aug 2013 at 13:44

You think it might be a problem if i don't have the static bag, i still have the box?

GavinG · 16 Aug 2013 at 19:32

Think i cracked it!

Can you have a look and see if temps, voltage etc are within limits?

I saved the default settings on a profile just in case and then tucked my balls into my pockets and tweeked the power saving options etc to disable Cool and quiet, boost and a couple other things i cant quite remember, that i was afraid to touch. lol

It's now at a steady 4.2 with no drops in speed or voltage.

I will keep an eye on it just in case, how long would you recommend i stress test for, i have been going for about 50mins so far?

GavinG · 26 Aug 2013 at 11:34

Hey folks,
I have 2 things that hopefully you can help with.

1) Can you check these settings and see i have everything i need disabled etc that i need to overclock?

2) When i try to overclock to 4.4 i get blue screen crashes, i assume this is because i don't have enough voltage? However if i try and find CPU Voltage it's got weird numbers that range from +0.775 to -0.800, which i can go up or down in 0.025 bumps. I also have the option of Auto and Normal. Can anyone help with what this should be? Am i looking at the right option to change voltage?

GavinG · 26 Aug 2013 at 21:46

Any advice peeps?

GavinG · 27 Aug 2013 at 23:18

Hmmm i've tried loads of settings this evening I think my cooler isn't good enough, anything over 4.3 is getting too hot 62+, (it's not bios crashing but 62 is getting to hot?) i've tried taking down the volts on a higher multplier to keep temps below 62 but then the computer is freezing so do you think I have reached MAX speed on my current cooler?

GavinG · 28 Aug 2013 at 07:14

Im at work now but from what I remember it's 1.320-1.395 depending on what I put in the cpu vcore adder

GavinG · 29 Aug 2013 at 10:26

That would be great swordfish
