Amd Fx-8350 OC problems

[Gamer2107]

Hello everybody,

I got myself a Amd FX-8350 a while ago and wanted to try overclocking on it.
I do not have a lot of experience with overclocking but i thought i could do some basic overclocking,
im running into a few problems.
i tried increasing the multiplier without changing the voltage (which is at auto 1,4V).
when i increased the multiplier to 20,5 (which is 4,1 GHz)it already went unstable @ 1,401 volts.
i tested it with prime95 and some cores went out after 10 secs.
at 4,2 Ghz @stock voltage it was even worse with some of them going out instantly.

I find this fairly strange as the stock boost clock is only 4,2GHz and i cant even reach that stably.
i tried increasing the voltage to 1,5V (and yes i know that's shit high) and it still was not stable at 4,2 GHz.
temps are not extremely high 63 C core load

My pc specs are:
CPU: AMD fx-8350
Cooler: Be quiet shadow rock 2
GPU: Nvidia GeForce GTX750ti (shity)
Ram: some cheap ram of which i dont know the name
PSU: Corsair CX600
MOBO: MSI 970A-G43
Case: NZXT S340 White

it might be my cheapo mobo
but i would like your guys feedback

TBH the 970 chipset isnt going to cut it matey you need a 990X 990FX motherboard to really overclock them

but isnt it weird how i cant even get it to reach 4,2 (stock boost) stably?

i also saw that with some people the stock voltage is like 1.34 volts, and with mine its like over 1,4 while not doing anything.
im running it at 4,1 GHz atm which seems to be somewhat stable as i've not had any crashes yet

you will only get a mild overclock with the board you have trust me I had 2 msi gaming 970's I rma'd both of them compared to an Asus 990FX sabertooth that I had the msi just doesnt have enough power phases

you can't overclock the chip because the VRMs will go pop and start a fire!
Your motherboard can't even handle the boost clocks on the 8350

 

[Gamer2107]

hmm well that probably explains the over 100C temps i see on some sensors in HWMonitor lel

this was a little bit after stopping prime 95

Chip set has nothing to do with it however the MSI 970A-G43 is a bad motherboard for 8 core cpu's
It has a poor 4+1 vrm set up without heatshelding.

thanks for the info everybody

I disagree I have overclocked on both and the 990X and 990FX are a much more stable chipset for overclocking FX 8 cores there

I ran a 4.9ghz stable oc on a FX8320 on a asus 970 evo r2.0 (it has 6+2 digi vrm)
Chip set is relevant for overclocking the quality of the power phases is what matters there are just as crappy 990FX motherboards around with poor vrm's that are not heatsinked.

lets just agree to disagree

I'm assuming you disabled AMD cool & quiet before you went ahead with overclocking as it will cause throttling and make the clocks unstable. You should always be manually setting your volts not allowing it to auto.

Actually for the fx-8350 the CnC is "disabled by CPU" Although I've turned it on and the chip turboes normally on my sabertooth

I can't get to see a pic of your board because I am on my phone.

Firstly, as I've said before, chipset has absolutely nothing I repeat NOTHING to do with how a board overclocks. It's all about being able to supply the necessary voltage to the chip.

I had an Asrock 990FX Extreme 3 and it only had 4+1 VRMs and thus the maximum overclock I could sustain on a 8320 was 4.2ghz.

However you are going about it all wrong. Leave the multi alone because it needs a ton of voltage that you simply can't supply.

Instead set the voltage to 1.4v absolute max (your VRMs will droop so 4+1 will supply around 1.38v max) and start increasing the FSB. The only thing you need to learn then is how to offset the memory clock as upping the FSB will screw with your memory speeds.

Just lower it until you are within 100mhz of your maximum memory clock. This for me was 1498mhz.

And please for the love of god can the noobs shut up about the chipset. Please.

Couldn't agree more, I used to OC with a GA-78LMT-USB3 and got great clocks with it. The chipset has nothing to do with overclocking on the FX series, so long as the board has the features available.

There's a guy on Overclockers who has achieved 5ghz out of a 8320 on a £35 Gigabyte MATX board.

If you know your onions a decent OC on just FSB alone can achieve very high clocks on not a lot of voltage.

I had a M5A97 is it? And managed an easy 4.5ghz on that. I wasn't limited by the board either it was because of the cooler (an old Scythe Ninja)
