Computer Case: COOLER MASTER Elite 430 (With 120mm front intake fan, 80mm bottom intake fan, and 80mm rear exhaust fan)
Motherboard: MSI 970A-G46 AM3+ (According to speccy, my motherboard temps idle at 25c. Under full load it never goes over 42c)
Processor: AMD Phenom II x4 965 3.4ghz (OCed to 4.0ghz @ 1.6vcore with XIGMATEK Gaia SD1283 cpu cooler. Idle temps are at 32c and under full load it reaches up to 50c. 1.6v is the only way i could ever get it stable at 4.0ghz.)
Video Card(s): HIS Radeon HD 6670 1GB GDDR5, HIS Radeon HD 6670 1GB DDR3
Hardrive: HITACHI Deskstar 7K1000.C 0F10383 1TB 7200 RPM
Ram: Not sure what this is, since this was just Ram i salvaged from a HP Pavilion P6000 series computer. But according to Speccy it says this for my ram, 4.00 GB Single-Channel DDR3 @ 666MHz (9-9-9-24).

Im a bit worried about the VRMS of my motherboard, ive heard they arent very high quality and they can blow up and cause a fire. What im wondering though is, are my VRMS safe with the temps im getting? Or do temps not matter in this case?

P.S.
Ive ran my CPU at 3.8ghz with 1.52v with the stock cooler for roughly a year now and ive had no problems.

Edit: Nvm.. Its not entirely stable. Id probably have to raise the vcore even more if i want 4.0ghz. Definitely stable at 3.9ghz with 1.54v tho.

could be they've been binning more tightly but since you've had for >1 year I think something else is up, maybe cheap mobo? how many phases is your mobo power?

Overclocking in MSI AMD boards?

Is your Phenom II X4 a Deneb RB-C2 or RB-C3? That's where the difference could be at.

Besides, what do you use your computer for? If you use it for gaming, your overclock should be severely stressing the Processor, Motherboard and Power Supply (A 4 GHz Deneb C3 is at over 190W), yet what is lacking there is the Video Card. Besides, what the Power Supply is?

C2's don't do DDR3 IIRC

no wait they can

good call

You're already pushing lots of volts through that chip; 1.6V is definitely something I shied away from with my own C3 965. Of course you're free to do what you will -- I'm just sayin'.

And those temps look too good to be true. I clearly remember having trouble keeping mine under the 60°C mark (3.9GHz@1.55V) with two crazy powerful 120mm delta fans strapped to a 212+ in push-pull.

So your 50°C is suspicious to me -- Though I was running intel burn test 50 times with something like 14GB of dedicated memory which heats things up pretty good, so that's an unknown variable, I suppose.

I'm running my Phenomii 965 at 4.0Ghz and stock volts 1,41V (1,45V) on cheap msi board.
It is MSI 760g-P43 (FX)
It has 5 phase VRMS without any cooling:

It does a good job so far. The difference in voltage may increase the power draw but with such a heatsinks you should be safe.
Anyway, pushing 0,05V more for just a 100MHz (from 3,9 to 4,0) is pointless. You will not see any difference. Sell your phenom, and get new one :p maybe better.
I wish I have a cooler that could handle increased voltage. I'm sitting now on DeepCool Gammaxx s40 and it keeps my temps around 50-55 in OCCT, so no voltage tunning for me;/

At 1.45v sure no problem. OP is pushing 1.6 and considering more. 1.6v is already alot. I wouldn't. MSI has a history of problems. My son is running a very similar rig to OP. MSI board, sli, 955be OC'd to 3.8 on 1.4v. For giggles we dropped in a 1090t and cranked it up to 3.8. We could HEAR the coil whine under load so shut it down immediately.

When I had my 965 setup i ran 4ghz at 1.5v. Dont recall the boards power phases though.

Its a C3. And my power supply is a Corsair CX430 v2. And i use my PC for gaming.

Hmm, lol i dont know. I think it may be because i live in Washington? It doesnt get very hot up here. I usually don't use any heaters in my room either so its for the most part, fairly cold in my room.

ya can you post a cpuz screenshot when running your stress test?

Hmm guess i just didnt run it long enough. At 3.9ghz its right at 50c.

I tried to do the same on my MSI 785g-e53. If you look the boards are pretty similar, I am sure they are using very similar components. So when I tried that my mobo blew up and my raid went with it, ofcourse no back up so it was a nightmare. Luckily MSI sent me the same exact board and everything was good.

you know 3.9ghz honestly isn't terrible. I know it's frustrating but as long as you are at or below 1.55v you are safe. You could just punch it to 1.55v and call it a day.

Of course there is the CPU-NB to overclock next ;) you can give it +0.2v and should get to 2.6ghz. That'll increase your speeds by about 15-20% depending on the game/load

Stop wasting your time and putting a ridiculous amount of stress on your components for little performance gain. Unless you play everything at minimum settings, what you need is a single, faster Video Card, or at least spend your time trying to overclock them instead of the Processor.
For general gaming you usually are GPU bound. You may want to compare going from 3.4 GHz to 3.8/4 and checking if there is a tangible FPS difference or not. If not, you're GPU limited. Keep in mind that everything goes by the law of diminishing returns, so if you're already confortable at 3.8, going to 4 GHz will bring a minimal performance increase yet still make power consumption skyrocket.

50C is basically your max, also with a 4+1 board I wouldn't go very high..


Surely wouldn't do 3.9GHz at 1.54v.
