How's my OC?

post #1 of 15
Thread Starter 
I'm new to this but I just got my system running today and want to double check my clocks. I got it running at 3.2ghz @ 1.3625v. I had to unlink the memory to get it to post. I'm running prime95 now with no errors yet and my load temps are 49,42,49,43 ambient 68F. What do I do next lol?

Thats a great O/C, what is your goal? then well work with you to get higher.

Thats some serious Vdroop on your board as well.... 1.36 to 1.28 is alot.

I wanted to try 3.6 but within 2 sec of prime95 blend I got errors and had to down clock it to 3.2ghz. I noticed the vdroop also. I wondering if maybe thats while I'm getting errors at 3.6ghz. I guess I'm gonna try the pencil mod to get it stable. That will have to wait for another day though.

Ok.... With your Vdroop, your gonna have to push some higher volts....


Try this

400*9
Vcore 1.4875 if you cant post at this i would set to 1.5.
Give your FSB and MCH (NB) a +.1v increase.

Also you ram could be holding you back as well. Make sure it's getting the appropriate ammount of voltage too.

Forgot to mention my temps at 3.6ghz got a little hairy. At 3.6 I tried 1.48v and as soon as I started prime95 the temps shot up to 61-62. I'm not sure if thats safe but I didn't like it lol. Heres the rest of my voltages:

FSB= 1.4v
Nforce spp= 1.4v
Nforce mcp=1.525v
HT nforce SPP=1.25v
Mem=2.1v

I pretty much just followed the 780i overclock guide to get this far. Following it further led to problems and questions so here I am.


Edit: It just failed a thread of prime95 after a half hour so it's still not stable at 3.2ghz. Lets work on 3.2ghz and after I pencil mod the board I'll shoot for 3.6ghz.

Yea, 60-63c temps are well within safe specs for the SLACR models. And like I said, from the picture you gave us, your board has major Vdroop. with your voltage set to 1.4, you cant be getting more then 1.32 under load, which isnt enough for 3.2 let alone 3.6.... You need to give your cpu at least 1.4875 in bios and see how she runs.

Ok I'll up the volts a bit and try again at 3.2ghz.



Okay I upped the volts to 1.4v in the bios. cpuz is seeing 1.328v. I'm gonna let prime95 run on blend over night and see what happens.

Thats some massive droop thats probably already hampering overclocking but that is still a good clock you have there. Don't be affraid to set vcore in bios even to 1.51v with a droop like that. Not sure if there is a vdroop mode for your board..

There is a droop pencil mod I'm going to try. The Good news though is that prime95 has been running 7+ hours so far with no errors on blend. Temps are are 55,48,56,48. How long does As5 take to set in? Thats a pretty big difference between core temps isn't it? I may need to reset the TRUE. What other tests should I be running to make sure everything is 100% stable? Should I switch to the small fft's or try memtest?
