Q6600 OC on 780i

post #1 of 11
Thread Starter 
Hi guys
So, after reading through the Intel Overclocking Guide and RAM 101, I am drowning in information... lol.

I've got a couple questions before I dig into my rig.
The 'Core Temp' program gives my temps at idle as:
Tj max - 100c
Core #0 - 34c
Core #1 - 25c
Core #2 - 30c
Core #3 - 24c
First of all, 100c seems high. Intel says 62.2c, so I should stick with that?
Secondly, is it normal for the core temps to be all over the place like that? When overclocking, do you go for the max temp of any one of the cores, or should they all be the same?

I tried to get nTune to install on my 'puter, but evidently the 780i mobo isn't supported yet. You'll prolly flame the crap out of me for even thinking of using it, but I was really hoping to give it a try...

Finally, just to get this straight: For a gaming rig, it's better to under-clock RAM if it will make it possible to tighten RAM timings? The idea on a gaming rig is to go 1:1 with the lowest timing numbers?

Thanks a lot for your help!

TJ max is nothing, you can ignore it. Thats not your actual temp.

10C difference between the cores is a bit much, you used the line method correct? Check the AS5 site for instructions on how to apply thermal paste on quads, make sure you get the line going in the right way. 5C core difference is fine but any more is probably a bad seat.

Ntune is crap, don't install it

Timings don't mean much on your rig with that processor. I would just go as high of MHZ as possible without having to go above 5-5-5-15. Same thing as the divider, just ignore it.. it means very little on new rigs.

To check for stability I would use Prime95 v25.6, as anything but the latest version won't work well on quads. http://www.overclock.net/downloads/137251-prime95.html

I use small FFT test to test for stability at first and because it will make your processor alot hotter than the rest, but use blend test for final stability checking when you find your max OC. I'd say about 8-12hrs of blend for final stability checking.

Your core temps will be within 5-6 degrees of each other, for the q6600 you don't want to go above 70c under load.

most ram timings come stock at 5-5-5-15 but 4-4-4-12 is what alot of ram is spec'd to use, but using a 1:1 divider is optimal.

when you test your load use prime 25.5 because it tests all 4 cores at one time without having to run 4 instances of the program

Ah crap, I was afraid you'd say that. I bought my rig online, and I'm less enthused about re-seating the CPU cooler than you might think, as I'm under no delusion about my ability to get it put back together better than it already is.

Thank you so much for the rest of the info.

bro - trust me: I knew nothing about building computers and in a couple days of hard core research on here i was ready to tackle it. i can tell you that it is extremely satisfying to build/repair. the thing is, responses come so fast on this forum that if you have a ? it literally takes a couple of minutes to have a couple of answers.

besides, you say you have a stock cooler. If your going to overclock to a significant degree, you should probably get a better cooler (all, correct me if i'm wrong here).

I installed nTune on my new system, just to overclock the GPUs. And even then I discovered nTune to be inferior to RivaTuner. And definatley, no way, should you use the "automatic tune" feature in nTune. I hear that really can crap out your system in no time.

btw - i have the same cpu/mobo as you.

using nTune is like buying a Ferarri and then hiring someone else to drive you around in it. you have a sick system, you should take pleasure in tweaking/modding it yourself.

you need to try the beta tools for the board, its in my EVGA 780i guide.

also ntune works but you need the latest beta version. The only thing I use it for is overclocking the video cards as riva has been fussy.

also everest beta (again linked on my guide) works well with the board

oh yeah, misread it. it's definately not seated right. that's what my temps looked like before i applied more thermal grease, now they are within 2-3 degrees of each other.

Ok to let u know im just a kid and I'm new to overclocking. I built my comp a few days ago.

My specs are:

EVGA 780i mobo
Intel Q6600 @ 3.0 GHz (stable, stepping B)
Dominator 1066 MHz Ram (2x1gb)
EVGA 9600GT
Artic Freezer Pro 7

I overclocked it to 3.0 GHz. It's stable but i want to oc it more. Can anyone give me some tips.
