965 @ 4.3 GHz Wall

post #1 of 23
Thread Starter 
I got a little bored a few minutes ago and did a suicide run on my sig rig, the highest I could get was 4.3GHz at 1.415 (though this board has a pretty good amount of vdroop so actually 1.407) and even with 1.425(actual) it wouldnt quite make it into windows.. I've noticed thats a bit of a pattern though, as I see people with 965s at 4.3 all the time.. Soo, out of curiosity, if you're reading this and you've gotten a 965 C3 over 4.3GHz and at least somewhat stable without insane amounts of voltage, could you put down some cpu-z validations?

And in case your wondering, I plan on using this cpu for a pretty good while, so I dont like going crazy with my voltage

Volts are way too low, don't be afraid to go up to 1.5v

Yeah.. I know I could go higher, its not like my cooler can't handle it.. Buuuut I dont want to chance frying this thing lol

You won't at 1.5v at least not in the short term. Just watch your temps and make sure your aren't getting up near 60c.

Volts are the only way you will get that OC stable.

Yeah.. If i were to take it to 1.45, It'd probably be stable, but my cooler cant quite take anything over 1.435 without getting into the high 50s

I'm just curious if anyone has gotten past 4.3 using less than 1.5v

Edit: For the record, 4.0 is completely stable at 1.395 on this chip

You think that's alot of Vdroop? That's like nothing, at all. Mine is from 1.4v to 1.352v.

You just need way more voltage, you're safe up to 1.55v. Don't be afraid of temps until you hit 62c on Prime95, which is the maximum safe temperature. Even with 1.55v the chip would last you good 3-4 years.

Please dont listen to these people. If you're vdrooping as much as you are with as low of a voltage youre putting into it, you'll blow your caps at 1.5 or 1.55. VRMs vdroop because theyre too hot, or if its too low of a phase. Look at your motherboard, to the left of the cpu socket, do you have 5 black boxes or 10? If you have 5 its 4+1 phase and i wouldnt reccommend putting more than 1.45 into that socket unless you get a good heatsink for them, or a spotcool fan.
Next time your running a stability test at full load and its vdrooping, touch one of those black boxes with your finger, ill pretty much guarentee you its VERY hot.

My motherboard used to vdroop like a ***** at 1.5 down to almost 1.45 (i have an 8+2 phase) but then i put a heatsink and a fan on my vrms and now i can put 1.6 into my socket rock solid.

Tl;dr be happy with what you have, or get better cooling, for both your cpu and your motherboard.

Your voltages are safe to go up to 1.6v without degrading the chip, but AMD recommends 1.55v the safe maximum.

Wow, how'd I miss the fact that he has a MSI motherboard.. Damn I fail today.

Don't OC on that board, it's barely safe for stock because MSI has horrible VMRs. They can easily catch fire while gaming or stress testing.

Really..? I got this board because its supposed to be great for overclocking
Also this board has a huge heatsink across the vrms and north bridge..
