Best thing is, that the temps are holding steady at 65c (IBT temps), whereas before they were reaching 67-69c when benchmarking at 3.6 Ghz with IBT. So I may have a little more room to move the clock up higher

Did you use my settings I posted for you? I reposted them in the P5Q thread for you the other day.

Yeah mish mash of my 3.4 Ghz and your 3.8 Ghz settings. And little guestimate on the vcore part.

Good on ya. Personally if i passed IBT i wouldn't bother with P95. guess it depends on how much RAM and how many passes though.

Yeah, agreed on the IBT part, but I'm doing it for the peace of mind. I'm running Corsair 4GB (2x2GB) at 455Mhz (actual speed).

Mind sharing some volt info?

Sure I will mate. Just need to let P95 doing it's thang, and I will post them up

Edit* Quick Q: Is it worth doing Small FFTs after the 12-hour run of Blend is finished?

[Earzz]

Woot nice OC truehighroller, what kind of fan do you use on your TRUE?
Another thing, with looking this much on XS it looks like it that the 45nm quads need less voltages on P45 boards.
I can be wrong but i just got the idea that im right, am i?

[Singh400]

Well my 3.6 Ghz failed, only on Core 3 and after 8 Hours and 2 minutes of P95 - Blend. So I upped the vcore by one notch and it's been running since this morning, should pass the 12 hr mark around 21:00 today. I'll post back then

Thanks, I am proud of her that is for sure. You might very well be right about the voltage part but, I'm not sure. I have 2 120mm Scythe's Push / Pull "high rpm ones".

If you've already done IBT, no.
But it would definitely be worth doing some...interactive...3d.......stability testing...

And then undervolting.

[Singh400]

We have 3.6 Ghz stable

Prime95/Blend has been running successfully for 12hrs+ without error. Temps average 50c.

Will post my settings up soon

If you've already done IBT, no.

Ahh, ok.

But it would definitely be worth doing some...interactive...3d.......stability testing...

And then undervolting.

Well the lowest vcore I can go with 3.6 Ghz is 1.22500. For 3.4 Ghz it's 1.17500 (sure this goes lower).

On to 3.8 Ghz!

hey guys,

I have a Q9400 @ 3.5ghz 1.39v with an X48-DQ6 motherboard and some Crucial Ballistix 2x2gb DDR2-800.

I try for 3.6ghz and i get a 0x00000124 BSOD and they say its due to my GTX280 or it just locks up straight away. I see alot of people with >3.8ghz and i barely can hit 3.6ghz.

Should I upgrade to a Q9550 CPU or head for a P5Q Deluxe? A mate of ours got one and had freezing issues with it, so he returned it. I was just wondering if they have improved..

You say freezing issue and I think of what is happening to me. What do you mean by that?

[Sil2]

Yes, Random Freezing. Anything he would do, would lock up for a few seconds and then start working again..Everything he did. He tried BIOS Updates and everything...new chipset drivers. Same thing happened to an EP45-DQ6 we had.

Ive read it 'can' be fixed by enabling CPU Margin Enhancement in the AI Tweaker in the bios of the P5Q Deluxe.

Or you can downgrade the BIOS to 0803 and fix it perminately that way with out ever seeing that setting again. They are going to be taking this setting out soon so, I am on 0803 because of the CME option issues with my 9450. Go to 0803 problem solved because no more option. I have a pretty big case open with Asus on this and as a metter of fact should be getting an answer bout the issue today.

First thing you should do is lower vcore!!! i don't care what board you're on you don't need 1.39 to this chip at any clock below 4ghz. After that I would take a look at your psu. What vnb are you using? X48 can go pretty high here, and with this proc you're going to need a vnb of at least 1.4~1.5, and as high as 1.7 to get the fsb you need.

I've already tried lowering my vCore and any lower im at 3.4ghz and less.

Ive already replaced my PSU. I went from a Silverstone Modular 850W to a Corsair HX1000W.

What do u mean by VNB? Northbridge voltage?

[Slovnaft]

yes, and that's a critical voltage. if you have this too low it might explain why you need such high vcore. And if lowering your vcore only gets you 3.4 then you're just going to have to live with 3.4
For example, try starting IBT on 1.39 vcore. Unless you've got an SS on i think you'll see what i mean.

[Sil2]

Okay, I just went into the bios and put the (G)MCH Voltage to +0.400..i have never put it higher then +0.075. It doesnt say what the real voltage is now or it was before i touched it either. I also put the FSB Voltage to +0.30..Same thing with that..doesnt say voltage now.

After i did that i put the FSB to 460 x8 to make 3680mhz and now i am priming it. I shall put it up some more soon and see how i go I couldn't get it to boot at 3.6ghz before at all.

Thanks Slovnaft

[Slovnaft]

Let's see, on my old GA-X48T-DQ6 my Q9450 topped out at 3.8 with 1.27vcore and the vNB i used for that was in the neighborhood of +0.5-+0.625 (don't really remember where) and the max vNB that board liked under air was +0.7, i believe. As you get up there you will definitely want to strap a fan on that NB hs.

You are kidding right? I'm talking about the 1.39vcore. Maybe you have a nice chip but the other ones are struggling with 3.6. Mine for example needs 1.38 to to 3.8(Q9450).
On a DFI UT X48 T2R the cpu wouldnt go over 3.6. So chipset and chipset implementation does matter.

I never said chipset implementations didn't matter. For example DFI X48 boards definitely have not been known for their great overclocking potential, much of that due to their sketchy memory compatibility. And chipset most definitely matters; X48 makes it much more necessary to have a golden chip, and the max you'll probably see out of a quad is aroudn 480 fsb at the high end (I bottomed out around there), whereas on a P45 with a little effort you can easily see over 500fsb (I booted at 8x510 maybe validated i'm not sure check hwbot).
The bottom line is, above 1.35v IS high voltage for this chip, whether you have a good chip (as I feel I've been blessed with twice) or a bad chip. If you're looking for a 24/7 clock and have to go up to 1.38 to 1.39 then you should seriously consider setting your ambitions lower and/or taking a look at your other voltages (like Sil who found his vNB was still at 1.0). Take it from me, I damaged my first one of these and fried my second (the one on my HWbot), both of which were epic clockers. Now my third, an actual Intel RMA, I'm going to treat like a princess.
I refuse to believe that so many of these chips are not getting to 3.6, especially having been with this thread in the first half when practically everyone was vying for 4.0+
These 45nm quad take very low voltages. Seriously, try it out.

[lowtcell]

Been tweeking my Q9550 all week. Still at 3.5 but I've been dropping Vcore a bit every day and priming for 12 hours at each drop plus some normal gaming, etc. I got down to 1.268 bios Vcore last night. CPUz 1.248 idle and 1.240 load. One of the prime threads failed after 3 hours, so I just set NB volts to 1.41 and tried again, and you know what? The Vdroop is gone. Now at 1.248 idle and 1.248 load. Is 1.41 ok for 24/7 on an X38?

[Big Lar]

@lowtcell, When I was running the x48 DFI 1.41NB was Nothing, and as the x38 is just the same with a different bin for the NB, IMHO I would say Yes, 1.41v on the NB is just fine as long as you have some air flowing across the NB and the temp of the NB is good.

Problem is, the p5e does not have a NB temp sensor

[Big Lar]

Problem is, the p5e does not have a NB temp sensor

Just reach in and touch the NB sink then, if it does not burn your finger, or is not real hot WHILE gaming or doing something intensive, you'll be ok.

If it does burn you, I have heard that Cold Water is best for burns, not butter like they said years ago, and turn the NB volts down until you get better cooling on it

As promised my 3.6 Ghz settings. Prime95 Blend 12hrs+ stable. And IBT stable.

Sweet voltage! nice clock singh!

[lowtcell]

Well, it don't matter. Only got 2 hours of prime before a thread crashed even without vdoop. I guess I found the optimal vcore for 3.5 (1.275 bios).
