    Also remember IBT will stress your cpu alot hard then any game or app out there. SO if your getting 70c on your core temps in game you will probably be around 50-60c. You are still in safe zone but yes you are getting close to the edge as far as temp goes. A better case or if you can try changing the placement of your case fans if you can might help. Some times if you reverse your air flow (have the back fan act as the intake and the front fans act as the exhaust) might help lower temps. Or adding fans if you can.

    But like I said IBT or LinX will stress the system alot more then anything else. If you want to push the system further you might have to stick with Prime as it will not heat up the cpu as fast but it will require you to run the test long to make sure its stable. 1-2 hrs is ok to get a base idea if its stable but should be ran 8-12 hrs+.

    With air your core temps are gonna be more affected by your ambient temp alot more then if you go water cooling which is why I did. Right now I have my cpu clocked to 4.3ghz and max core temp gets to is 80-85 doing 20 passes of LinX at max ram.

    EDIT-- I dont remember which cooler you are using now. You might want to invest in a better one. I dont know which one to suggest to you but other people here might. They are not that expensive for a good one probably around $50-$70 USD.

    I wish I could put more case fans in, but I cannot, there is no rear exhaust fan, except for the PSU fan and I only have 1 intake fan in the front and 1 exhaust fan on the top of my case, unless I cut a hole in the side of my case for another fan. But there is no room for other fans as is

    I wish I could have a better HS but the only aftermarket HS I could get was the Zalman CNPS8700 for quad cores because its the only one that was short enough to fit in my case. My PSU is mounted directly infront of the CPU and HS so when you open my case you see a big PSU in the top left corner sitting right over the CPU HS blocking it, thus making me able to only get a HS that is no taller than 3 and 1/2 inches from motherboard to bottom of PSU

    I hope I can at least make my system stable and temp safe at least at 3.0Ghz cause with it set to 3.0Ghz atm I already notice things are a bit more fast and responsive ^^

    thanx again for replies guys, I'll post when I get back from my trip on sunday

    I don't know where you at on this Brigs, but these settings work well for me. Although, our memory is different, I can run all your memory settings with the exception of static tRead. I have to run an 8. Also my memory voltage can be set to 1.8 volts where you need at least 2.0 I think.

    Without good cooling, you will be limited on what you can do. If money is a pinch, add a 200mm fan to the cases side (yes it requires cutting/drilling) but that would help A LOT. You can get one of these fans off eBay for under 20 bucks shipped. Also, the q9550 is a great chip and will do wonders in the OC world. There is no reason to think you can't have it running at 3.4-3.6 + with very little tweaking using what you have already.

    Also, on the above post, I would change these:
    CPU EIST Function.......: [disabled]
    Virtualization Technology..... [enabled]
    MCH Core 1.30V
    ICH Core 1.20V

    Well I am back ,and have caught up on the thread with some good posts, thanx again ^^ First, I see your BIOS config conners, and it looks great, you didnt even have to change the voltage on your cpu core or pll or vtt, wow. See now, I upped all three of mine cause I got reboot loop when I set all those voltages manually to stock as you did, but, at the same time I had the 2.00B strap memory multi and not the 2.00D strap multi. Chike was saying that it was probly the B strap that was causing the reboot loop and possibly not the vcore, vtt and pll voltage.

    So maybe I should put my vcore, vtt and pll back to manually set stock voltage and just have my memory multi changed to D strap as it is now, cause it booted just fine when I changed the D strap, but I also upped all the voltages at the same time when I did that change so I have no idea what made it boot just fine; I should have tried one thing at a time ><

    I also did the temp test that Chike was talking about and the results are~

    With room ambient temp at 75F~

    -case open with fan blowing on it I got CPU= 31c and Core 0= 39c

    -case closed ,same room temp, I got CPU= 38c and Core 0= 45-46c (was dancin around)

    this was all done with computer on idle.

    So thats where I stand atm, I think I will try what settings you got there Conners and see if it was my B strap that was causing the reboot loop instead of the voltages. (cause I was barely OC'd to like 3.0Ghz, I wouldnt think I would need voltage increase for something small like that lol)

    thanx again for all input fellas!

    Do the open case with load, 1-2 IBT loops would be enough, seems there 's room for improving case vantilation.
    Is the PSU mounted sideways and the CPU HS right under it? Never seen something like that.

    Yes the friggin PSU is mounted sideways right over the damn HS, you have to remove the PSU to even work on the HS for the CPU, awful design

    Ok now also, I will try the IBT 1-2 times with case open and fan on it, but I also have some other news.

    I dropped cpu vcore, vtt and pll manually back to their default settings but kept the 2.00D multi and it booted just fine So, I am thinking, you where right on the money when you said it was probly the multi that needed to be changed to D strap to get it to boot fine. So, since it booted to windows just fine, I went ahead and ran IBT 5 runs max stress 4 threads and 0 errors and the highest my core 0 temp got was 66c instead of 71c before, so now I am running a prime95 small FFT test for awhile to see if its stable so far, (if thats the right thing to do?)

    So do I sound good so far? Cause I took conners advice in his BIOS post above for the voltage drops to default and left the D strap alone and all seems fine atm, should I keep goin with the Prime95 test and see how it turns out and then go from there? Hopefully getting to 3.2-3.4Ghz ;)

    Edit: I see that Conners has Load-Line calibration set to Enabled and mine is Disabled, should I change it to Enabled? Whats it do?
    thanx again y'all ^^

    IBT 66c with closed case? Do you still get the same 37GFlops?
    LLC is a bit of a cheat, you set lower vcore but in fact under load it might be actually higher than with 2 ticks up and LLC disabled.
    I guess you can use it if you want, I wouldn't. With LLC disabled you may be overvolting a bit at idle and under volting at load but you know what is the max voltage applied.

    Yeah you can disable Load-line calibration if you like, but if you do you'll need to raise v core maybe on notch. Also you can disable ESIT Function under Advanced settings.
