QX9650 @ 4.0GHz Possible with Stock Intel HSF?

[AuDioFreaK39]

I just recently bought a New in box Retail QX9650 for $700 from the AnandTech trading section, and I'm very eager to get it up to decent clocked speeds. The problem, however, is that I won't have enough funds for a water cooling loop until around June, and so for now this is a temporary solution as I need to work with what I'm already given. As most of you know, the new stock HSF on the QX9650 is a major upgrade from the standard heatsinks that Intel issues with their non-Extreme Edition CPUs

I'm going to be applying Arctic Silver 5 to the copper baseplate as my thermal compound. Eventually, the CPU will be lapped down to a 2000 grit finish once I have the water cooling setup, but that isn't an issue right now. The CPU will be installed on the specs in my sig.

And now to the questions:

1) Considering the speed of my RAM in relation to the 1333MHz FSB, what would be the best multiplier/FSB combinations to attempt for a 3.8 - 4.0GHz overclock?

2) Will EIST and C1E do me any good as far as idle power consumption in this case, or should I just leave them disabled?

3) Considering the heavily dependent nature of quad cores on FSB frequency, should I be more focused on a higher multiplier or a lower one?

Any suggestions are appreciated. Thanks in advance.

Does the included cooler look like the one on the left?

I've never tried the retail cooler however it may have no problem at 4GHz as long as the voltage is not too high. (< 1.4V)

I disable EIST and C1E personally. 400x10 is probably the best bet for 4GHz on that CPU. You can always change your memory ratio if your ram can run that fast however outside of benchmarks there's little real world gain.

Yes the cooler looks exactly like that. I'm gonna continue to leave EIST and C1E disabled. 400x10 was what I had planned as well. Thanks for the reply.

depending on voltage i have to agree with ruby.

We cant tell you if its okey without knowing what 4.0ghz will take.

And i can tell you, they dont all act the same.

Thanks. Any other suggestions?

4 ghz is not possible on stock cooling in my opinion, unless you have a special chip that runs 4 ghz with 1.2v, then the heat output might be reasonable enough.

I run 1.35v under maximum load, and the cpu loads in the high 50s while the cores are in the high 60s. and this is under good water cooling (copyright Aigomorla).

With good air cooling, those temperatures would be at least 10c higher, and under stock cooling... well I'll let you imagine.

Check out the little engine that could. This puppy is running on the Intel Stock cooler idling in the mid 60's and goes off the chart when priming all day without locking or producing an error. :Q

Conclusion - stock cooler is totally inadequate for anything more than a mild o/c or test ONLY.

Well the stock HSF for the qx950 is very nice. So if you can bump the multi and bring the FSB up a little you will be okay on the retail HSF just don't go over 1.35 / 75 C.

Is that the stock cooler for extreme edition chips?

It came with the QX9650's we got. QX6700's (even the B3 furnace) had a smaller one like on the right but with a blue fan that hits 3600 ear splitting RPM.

Difficult to say if it would work are not. The first thing you need to decide is, what is your upper limit to temperature? Everyone has their own guide for this. No one has that answer. Some people don't mind high 70's for their cores, others get their panties in a bunch when the cores hit high 50's. It all depends on who you are and what your personal criteria is when finding an answer for these questions.

If you can run your chip at 4Ghz on a stock cooler with temperatures that you find acceptable, then you have your answer. If not, then just wait until you have your water block.

What do you mean by "...the QX9650's we got."? Who is this "we" and are you hiring???

LOL....

Sorry if she told you, she would have to shoot you to keep it internal.

I'm a panty buncher at high 50s, heh.

audio lower your ram speed to around 800 something using 1:1 divider.
Tighten your timings to 3-3-3-8

Those sticks can do that @ 800-900mhz /w 1.95V Make sure you put active cooling on it tho.

I've got the 8 x 128MB modules though...the higher density. Right now I'm already running them at 2.15v with active cooling. What do you suggest?

How much Vcore does yours require to make 4ghz?
If I were you, I wouldn't use stock HSF for any overclocking a $700 chip.

Glad you took that as a joke, which is what it was... I mean no disrepect to people who want to play it safe.

Those arent the standard tracers? If they are those are the exact sticks i have. Black PCB, with leds at top.

Losen to voltage on it. 2.15V is not safe. I zaped a ram stick @ those voltage. Also zaped it @ 2.1 and 2.0.

They dont need a lot of voltage to get good clocks.

They're made to run at 2.2v, says right in the specs, and I've been running them at 2.15v for a couple months now. How far are you able to take yours @ 2.1? Timings?
