Yeah, 90 degrees doesn't sound very cool. Generally you want to keep below 50, and definitely below 70.
PSPkiller Wrote:Also where did you hear that a single rail was better than multiple rails? More rails are definately tha way to go. If you've got a high load on one rail (e.g. the graphics card) then it doesn't effect upon the rest of the system. You end up with far more stable power. The fact that your 12v rail is at 10.5v is cause for serious concern. Replace that power supply now! Preferrably with a multi rail pwer supply.
Wouldn't you think it's the same? I mean all the rails come out of the same place, and so if the draw is too high on 1 rail, it'll effect the others as well, no difference how many rails you have. Think of your home main power supply, you can have 10 outlets around the house, but if you draw massive amounts from 1 (stick a few 2000W water boilers on it), it'll take out the other 9 too.

I have been running it on max settings, and been making it through all the passes. I am still unsure about how to make sure Prime95 would be run, with everyone being vague and just saying to have 2 instances of it open, and that's it.
I'll be likely to get a new PSU, then. Thanks guys.
I guess another option would be to disable hyperthreading so the 4 threads of Prime95 covers your whole CPU. But then that may effect your "stress" levels (probably less stress without HT).

Not quite. A compyter PSU isn't one single power supply. It's actally a few power supplies all in one box. There's 3.3v, 5v, 12v, 5vsb and a few others. (Like the negative supplies. They're not used much anymore.)
("PSU" = The metal box with a fan and a merasse of wires coming out the back. "Power Supply" = bit of circuitry within the PSU that converts mains voltage to whatever voltage is needed.)
Think of it like this. A multi 12v rail PSU has more than one 12v power supply in addition to all the others. You'd want to try and keep all your comonents to their own rails, especially the graphics card. As that draws more and more power it only strains that power supply and leaves all the others to their own business. Yes, all the power supplies are fed by the same connection to the mains voltage but that can provide a huge amount of power before it comes under any kind of strain. In the UK the average mains socket can provide 13 amps at 240V AC. (I'm going to get all electronics-geeky here.) You can work out just how many watts of power a socket can provide by multiplying the voltage by the amperage. 240*13=3120w. Most high end power supplies are around 70% or more efficient. 0.7*3120 is 2184w. The mains supply therefore isn't a bottleneck.
tl;dr get a new PSU.

Ok, makes sense I guess. I never really researched into this stuff, I was just guessing based on logic, thought all the 12V rails would come from the same 12V source.
Oh, and I never said the mains would be the bottleneck, that was just an example.
I do have a question, however. Is the slowdown likely due to the processor being hurt (or bottlenecked?) by the rail? If so, could there possibly be a change in the performance, or would it likely all be permanent damage? I am afraid it is going to be permanent :(
Theres always a possibility of permentant damage, especially consistently running at temperatures like that, but since your running at 1v out of the 12v's norm, its a fair garuntee your PSU is fudgeed, so see what happens when you replace it
Push comes to shove, it might still be under warranty...i don't think i7's have even been out 12 months yet have they?
No, they were released right at end of Dec 08, so it hasn't been a year.

Just based on that temperature alone, I'd say your CPU's definitely broken, unless your fan broke (unlikely?).
I have contacted both Corsair and Intel's customer service. Corsair hasn't responded yet, but I am hopeful. Intel wants me to do the troubleshooting steps of reapplying thermal paste (did that when I first had a temperature problem), and updating my motherboard's BIOS. I'll update the BIOS now, and reapply the thermal paste tomorrow... if I can find that stupid tube XD.
Thanks for the help, guys. So far I think this will be fixable. I'll keep you updated (if you care).
I think the moral of the story here is always buy a decent quality PSU (not saying you didn't it's juat that it probably would have been worse with an el cheapo PSU) and use a surge protector. Hell, while you're at it it might be worth buying a small UPS just so you have a few minutes to get everything shut down safely if the power goes out again. Pretty much all UPS's have a built in surge protector as well.
* PSPkiller doesn't use a surge protector or a UPS... Then again I've never had a hard drive failure either so maybe the computing gods like me...
Lol, yeah, my dad rode me about not having a UPS. To tell you the truth, I thought it was just another name for the PSU, and never really connected the dots as to why my dad would have power for a while during a blackout XD
This PSU is actually quite a good one. Everything I'd heard about it was nothing but praise. I just need to learn to cover my butt, right? :)
Another thing... I just flashed the updated BIOS, and when I was in the BIOS, I checked the voltages, and it had the +12V rail at 12.03. Does it change after you log in? I just checked SpeedFan after logging back in, and it was still at 10.57. Depends on the tasks and load, I suppose?
