You will need more than likely around 1.3v in order to achieve stability at 3.8ghz. For my chip, I was 24 hour prime stable at 1.3625v.
As far as you your CPUz reading. It will always be lower than what you set in bios. The difference between your bios setting and CPUz readout at idle is called Vdrop. Voltage drop between idle and load is called Vdroop. A feature called LLC (load line calibration) effectively removes Vdroop and Vdrop by circumventing the design characteristics of the CPU power system. With a board that has different levels of LLC, like mine for instance, with a max LLC setting my bios Vcore and idle CPUz vcore are almost identical. My load voltage is the same also. The only issue with LLC is that when your CPU goes from idle to load, and load to idle, the voltage will spike above the setting that you have dialed in. For this reason, LLC can be dangerous at higher vcore settings, as the voltage spike could lead to premature degradation or failure.
Your motherboard may only have a couple options for LLC, more than likely you will have the option to enable it, or disable it. If your board is anything like mine was, the LLC left something to be desired. In my case, even with it enabled, my Vdroop was still present, although not nearly as severe.
At any rate, the first thing you need to get situated is your cooling. 80c is no good, especially at that voltage. I suspect you have air bubbles in your TIM, or your cooler isn't secure. Let us know what you find!

Yeah... you were right about the vcore. It was set at 1.36v (and CPU was @ 3.8GHz). I dialed it back to 1.3, thinking that would help with the temps (I also re-seated the cooler as well as I possibly could to insure no touching after cleaning with no-lint cloth and alcohol, no air bubbles, screwed down nice and tight... I even tinted both surfaces). It resulted in the cpu running @ 3.6ghz and then when I went to run OCCT to see what the temps would do I got the bsod. So I don't really know what it did for my temps. It looks like I'm going in the wrong direction and made my machine even more unstable by lowering vcore. I'm going to try to attach pics of my BIOS to see if there are some evident problems that I'm just totally ignorant of. Thanks. oh... and my LLC options are enabled, disabled, or auto. Should I keep it on enabled?

Try running at 1.36v again, as you may need that much to be stable at that clock speed. Most Q9550's run out of steam between 3.8ghz and 4.2ghz. You really need to mess around with settings to get it stable at the higher end of the spectrum, and even then, a high end air cooler or water cooling is necessary as 1.45v or higher may be needed to get to 4ghz or higher.

It all depends on the chip and the board.

At any rate, try switching back to 1.36v, watch your temps and see where your at. You should be somewhat cooler on the temps at the very least.

Thanks. I'm back at 1.36v and have adjusted some other settings and seem more stable but I'm still running at 3.6GHz. Running Intel Burn test goes okay but my temps do touch into the low 80's and I get nervous so I shut the test down. I'm thinking that if I raise my FSB freq to say... 475 instead of 450 that that will get me moving towards 4GHz (I forget the "why" specifics but I know I have them in my notes), and I'm wondering if I should look at upping my multiplier from 8 to 8.5. I know (think) that both of these moves will increase my cpu temps even more, so I'm strongly considering moving to a liquid cooler.

That said... I'm looking for some recommendations for a liquid cooling solution for $100 or less. I probably shouldn't be stingy when it comes to paying for my cooling hardware but I'm pretty broke right now. As always, I appreciate the help. smile.gif

Honestly, I believe even a more modern air cooler should do the trick, but liquid cooling would be better, provided you were going with an actual loop and not a corsair/antec unit.

This is my TC Folding chip. 100% stable. Have had it to 4.25Ghz, but backed off. A little much for it!

Need some info! What type mobo, RAM, etc. If you happen to be running a GA-EP45-UD3 series I can probably help. And by the way, the above clock is low. I was folding 100% stable at 4.16Ghz. before I backed it off due to hardware change in TC. I'm now running a GTX560, so clock speed on the CPU is not important anymore.

Hello guys !! I want to buy one Q9650 or Q9550 very good batch for overclok 4Ghz but with low voltage... Who have one chip for sale ?

Hi. I have some question regarding 132-YW-E179 790i FTW and oc q9550.







Any who has oc on this mb or a simular one?

I have seem to hit a wall around 3.5Ghz. But to tell the truth, I have no clue about how intels cpu and mb behave.

But I ques perhaps that cpu fsb voltage is related to the fsb I use to oc the cpu. How do i proceed to find the weak spot? lowering everything but fsb and see how far it can go on 1.1v? If I raise cpu fsb v, would that perhaps make the cpu oc higher?

Any who see any other wrong settings in my bios?
What is gtlvref lane? Do i change these?

And why does the voltage fall so mutch when starting to work? On idle it shows alittle more, but quite less that 1.35 witch I have set in my bios, I think it is 1.32 idle and 1.3 on load or something like that..

Thanks
