Is this good? The temps are when prime95 has been running for 9:20.

Ugh, my computer literally just stopped working not five seconds after I posted my previous post. Any idea what went wrong?

Read the guide... what was your error code? How can we know what went wrong when you tell us nothing?

Try to do a Linx run too, things that are prime stable sometimes aren't Linx stable.

Well excuse me mr. attitude. I don't know how to get the codes. It didn't clearly explain how.

q: My computer restarted while priming; how do i find out the error?
A: If you haven't already, disable bsod restarts in windows. Sometimes, though, it decides to restart anyway.

In xp you want to find a program called event viewer. Directions from ms:
Quote:
# click start, and then click control panel. Click performance and maintenance, then click administrative tools, and then double-click computer management. Or, open the mmc containing the event viewer snap-in.
The errors should be under system.

In vista from petri:
Quote:
Open computer management by right-clicking the computer icon on the start menu (or on the desktop if you have it enabled) and select manage. Navigate to the event viewer. Note: If you did not disable uac (read my "disable user account control in windows vista" article) then you will be prompted to consent to the action you're about to perform. Click continue. Note: You can also open the event viewer by typing event viewer in the search box and pressing enter, or typing eventvwr.msc in the run command.

prime 95 errors:

Freeze: Increase the vcore

other errors can indicate instability with the chip if they are during small fft (increase vcore by .125) or instability with ram large ftt (try raising the ioh and/or running memtest).

Bsod code 101: Increase the vcore. I recommend increasing by +.025 if you get a bsod

bsod code 124: Increasese or decrease the qpi/uncore by .25. Depending on where you are in your stability tests you'll probably need to increase it. 1.375 is the max i'm comfortable with although people say 1.4+ is safe. This is for you to determine and research. Don't do anything you're not comfortable with. Intel says do not go above 1.35 so 1.375 with droop and loss is safe and not too outside specification.

It is important to note that sometimes qpi can be too high and that might cause this code. That's why it's not a good idea to just set things to 1.35 and hope for the best. If you find that increasing qpi/uncore voltage is not increasing stability, try decreasing it. Just remember of course, to keep track of your settings. I recommend not increasing, unless you have to (don't be arbitrary about it).

D0 exclusive bsod weird 2 letter/number codes: Treat this as a 101 and increase vcore by +.025. Update: It seems that these error codes can crop up for other reasons. Depending on where you are in the process you should take a look at your other voltages. I realize this is vague, but you may need to experiment.
You're welcome

Thanks. I looked at the event viewer, but I have no idea what i'm looking for or anything :/

My computer screen just went black and it wouldn't go back to showing anything so I just restarted it.

increase CPU voltage by +0.25, see if that helps.

general rule: if it crashes immediately under prime = add more VTT

if it takes a while = add more voltage to vcore

Ah okay. I was thinking about doing that, but I looked at other people's vcore and some where running lower vcores than me at the same speed.

Is that just b/c of the different mobo or cpu?

I got BSOD 124 running at 21*196 (4.116 GHz)

My qpi/uncore is currently at 1.35 should I go a bit higher or lower?

The computer rebooted in the middle of ripping a DVD.

up the vcore. it's most likely because your cpu needs more voltage... everyone's cpu is different due to variance in the manufacturing process, some take less voltage to get to a high speed than others and vice versa.

qpi/uncore is vtt and 1.35 is fine and maybe actually more than you need.
