I would try to boot into safe mode and see what happens first? If you can get in you can uninstall your drivers and/or reinstall them.

I think this is cool if you are an OC'er, but this build is for my friend who will not be doing any of that...so with that said...

how the hell do you disable that feature?!?!?
In bios you will need to disable the A drive and also change the primary boot device to the harddrive and also disable 2nd and 3rd boot device's to disable. this will help to speed up boot time.

Im going from 4 x1gb xms2 to 2x 2gb this month anyway, just have to decide on a good flexible RAM brand thats readily available here in the UK. Then its a 2nd xfx 8800GT this month and i'll be a happy man!

Well i will when scan get the friggin T.R.U.E back in stock. It's a nightmare to source locally over here. got a 120mm scythe fan waiting for it here all ready to replace by AC7, its a bit too toasty for my liking.
Glad to hear my suggestion worked. Computers are all based on theory!!!

The TRUE's are finicky things. I lapped one of mine this week and got worse results (although before lapping it was pretty amazing). Went back to work on it and now my cores top out at 52C under orthos with 23C ambient at 3.6 on a Q6600. Thats pretty impressive especially since my silverstone beastie fan (110 CFM) is set at its lowest rpm by fan controller (1100 RPM or so).

How did you end up fixing your temps? See, I want to lap my TRUE, as 2 cores are running ~8C hotter than the other two on my Q6600. The only concern I have is the TRUE's surface is supposedly made slightly concave on purpose to match the 775 CPU's slightly convex surface (or vise versa, can't remember) - and I don't want to lap my IHS. What do you think I should do?

Sorry for the slightly OT Question. At least I received my 780i motherboard yesterday and plan on putting into action soon. I may just lap my TRUE as well since I'll be opening everything up anyway.

Hi all,
I have the XFX 780i, which is the same board as the EVGA. I've been having a slightly strange effect. After acquiring and lapping a TRUE and my CPU recently, I decided to up my day to day overclock form 3Ghz to 3.6Ghz on a G0 Q6600. With 1.45 vcore and 1.45 SCP voltage I am stable for over 8 hours small FFT in prime 95. Core temps top out at about 58 and SCP at about 55, so that's fine too. I can also pass memtest with the settings in my sig.

Here is the interesting part: I participate in SETI@home and a few other BOINC projects. When SETI runs it freezes the system after about 20-40 minutes. I thought small FFT's where supposed to be the gold standard for stability tests, but it looks like maybe BOINC is exposing some issues. Am I going to want to up vcore to stabilise the system? Or maybe more SCP voltage? Any thoughts? Or am I just going to be experimenting.

Thanks in advance.

Hmmm... that's interesting. I also thought Small FFT's was basically THE stability test to run. It basically maxes out processing and L2 cache with maximum temperatures as well. I have no experience with SETI@home so I can't say this for sure, but it could just be a problem/issue with the program itself. Are other users of SETI@home experiencing similar problems? Maybe you could check on the S@h Message Boards.

I doubt it is an issue with the seti application. It was completely stable 24/7 when I was running at 3ghz. My thinking is that the issue is most likely related to the board side of things rather then the cpu, as seti as a heavy memory user.

What voltage did you set for your SCP for your 3.7ghz signature overclock?
