amd8350 overclock

[atsidas]

Morning guys.

i'm new unexperienced with overclocking. I recently bought an AMD FX 8350 4.2GHX Turbo boost.

i want to overclock it to 4.8-5ghz. any ideas??

system specs:
amd 8350 fx
GA-970A-D3
corsair ram 2x8gb 1600Mhz

thats an entry level board and a top tier CPU. you should not overclock on that board.
get some heatsinks on the VRM chips on board, then try.

if you overclock now, there is a risk of damaging the board especially since you are new.

you can get heatsinks at frozencpu, performance pc, and even electronics hobbyist stores.

Alright my friend

So far i have just bought a coolermaster 240 for the water cooling of the cpu!

 

[Shou Miko]

one thing you should take in mind, using a watercooler won't bring the same airflow around the cpu socket as air cooling do, and specially not on the vrms around the board.


your Gigabyte board was prepared for some VRM cooling because of the two mounting holes there are, but Gigabyte didn't put it on because it's a cheap board, the more expensive board like the D3P got the vrm cooling and it's more or less properly the same board as the D3.

the layout of the D3 and D3P looks alike on many terms but different colour and companions are mostly used.

So what u suggest is to leave my amd at maximum 4,5ghz?
Otherwise buy a vrm cooler?

Id get a different board all together before trying to overclock. Those AMD chips pull quite a bit of power when overclocked, which puts, more stress on the VRMs.

 

[atsidas]

Pffff!!! I bought it a month ago!!!

But what mobo u suggest?

 

[MxPhenom 216]

Pretty much any decent 990FX board.

Gigabyte UD5 is what id get.

 

[RCoon]

For 4.8-5Ghz you need a motherboard made of more than paper, carboard and spit, capable of supplying around 1.45v+ on the core, and cooling on the VRM's, provided your case can provide airflow over the heatsinks on said VRM's.

Perhaps you should have done your research on motherboards before buying all this gear?

MSI GD45
Asus Sabertooth
ASRock Extreme3/4
Gigabyte UD3

All decent 990FX boards.

 

[atsidas]

What about this?

First of all sorry for my horrible english, I'm going to tell you my own expirence, I have a fx 8350 and first a cheap motherboard Asus M5A78L-M/USB3 and with a noctua NH-U12P SE2, my best stable oc was 4.4 with 1.481 v (I dont belive this value ,the true volt was much lower but this was the setting on the board), then i bought a sabertooth 990fx r2.0 and with the same cooler the max oc was

4.5 , 1.4 v llc extreme(on load 1,44)

Then bought a Phanteks PH-TC14PE and now my max oc is

4.6, 1.44375, llc extreme (1,48 on load)

Now in perspective maybe dont worth the extra expend for only 200Mhz, howeber this motherboard has sli/crossfire support, very good bios and software,temperature sensensors..etc.

I think you could oc but this motherboard is going to be the limit, and maybe with good cooling 4.4 like me or something like that. You dont say what cooling solution you have, and this is important beacause maybe this is going to be the limit to your oc before the motherboard.

My old cheap motherboard lie a lot, i try 1,55 y the temps was the same 50º on prime 95, so the problem could be not to broke something, the problem is going to be provide enought power for 4,8.

Maybe i have bad luck with my cheap but for prime 95 stable this is my volt requirments.

 

[atsidas]

Thats my cpu coller

 

[RCoon]

What about this?

Solid, good quality motherboard, I had one but the Z77 for Intel version.

 

[DiegoHH]

Wow!! the motherboard is definitely going to be a problem. Good cooling.

 

[atsidas]

So far catalyst at auto tune gives me maximum 4,6ghz!!! But its not stable!!! I want 4,6+ all the time!!! Not in turbo mode

 

[DiegoHH]

New motherboard or less OC. but try to find the limit of your board. what voltage are you using?llc?

[atsidas]

Maximum 1,35-1,4V

 

[DiegoHH]

I need 1,44 (on load with llc 1,48) for 4.6, you need more voltage i think.

 

[DiegoHH]

Catalyst auto could be a start but this is what i do

-First of all read a some tutorials. CrackerJack post 2 good ones.

-Disable Catalyst auto tune,i prefer bios

-You are going to need visit your bios and reset a lot of times

-Disable turbo and cool and quiet and c6.

-LLC is important, i leave in auto but beacause on my board is similar to extreme, on you board i dont know maybe better set manual on extreme. You could try and see the diferent volts on idle/load.

-Try something like 1.4 and 4.5 (multiplier 22.5), test with prime 95, 10 min, watch temps carefull

-If not stable, more voltage, if stable more Mhz.

-Temps must be under 60º on prime 95, if go higher stop test and put less volts.

-When you find a stable Mhz /volts use normal your pc and if when you play crash put a little more voltage.

-Play temps are like 10º/15º less than prime95 , so 60º on prime95 is not that bad. (45/50 on load in real world)

 

[atsidas]

Thanku DIEGO!!! U r the best

 

[de.das.dude]

dude do not even try to overclock on that board because you will pretty much fry it.
should have got a better board rather than a budget one if you are looking for overclocks.

i have an asrock 990fx extreme 4 and it gives strong stable voltages.
also since you have gone watercooling, you should REALLY invest in some VRM cooling because there practically,wont be any airflow there.

sabertooth 990fx, i have the first version, use a h100i and only managed to get 4.4 stable (with reasonable temps and noise levels.) 1.36 volts and all loadline calibration settings at max.

in the end I got bored with overclocking, replaced my gtx680 with a gtx 660, (2133 with the 1866 ram) and put the gtx680 in a h87/i3 4330 (bought the 4330 for 109) system, and found that i did not notice any real differences compared to the oc'd 8350... (3dmark physics scores were lower of course.) (and not being a great gamer, perhaps that is why i did not notice any differences)
(perhaps it is the 16x pcie 3.0 on the h87/i3 4330 compared to the 16x pci-e 2.0... )

 

[d1nky]

its all about vrm design, as lots of others have mentioned DO NOT OVERCLOCK on that motherboard. you'll end up popping a vrm from heat/stress and could potentially damage the cpu.

p.s but that msi 990FX has many horror stories about poor power delivery and design.

best bang for buck mobo, sabertooth.

 

[Tatty_Two]

Just checked some reviews on the OP's board, seems they have a high falure rate when overclocking due to poor cooling, often resulting in difficulties with the RMA/Warranty process...... proceed with caution!
