Hello,
Just a general query regarding relative core temps. I believe Core0 and Core1 should usually be very similar, maybe only 1-2C between them. At idle my Q9550 always seems to have about 4-5C difference between the first two cores. I don't get any overheating problems, except perhaps when playing Far Cry 2 and the odd BSoD error happens (unfortunately, the error report is corrupted, so I'll never know what it's trying to tell me).

More about : q9550 core temps

The latest - I just got another BSoD playing Far Cry2 and have examined the RealTemp log file. My GTX275 peaked at 85C (that's normal), the CPU at 67C (also normal) and the CPU load at 57% (seems normal too). Here's the relevant bit:

02/11/10 16:31:25 67 60 61 64 84 33.0
02/11/10 16:31:30 67 61 61 63 83 33.7
02/11/10 16:31:35 67 60 61 64 84 32.5
02/11/10 16:31:40 67 60 62 63 83 31.2
02/11/10 16:31:45 67 60 62 63 84 29.9
02/11/10 16:31:50 67 59 61 64 84 28.8
02/11/10 16:31:55 66 58 60 63 85 12.0
02/11/10 16:32:00 66 56 57 59 80 14.0
02/11/10 16:41:45 29 26 27 27 46 6.0
02/11/10 16:41:50 29 26 27 27 46 0.1

There's a constant 6-8C difference between C0 and C1. Is this normal? Could this be causing the BSoD?

67 seems a little high. Have you tried reseating you heatsink? My q9550 sticks around 50c under 100% load on air and I'm overclocked to 3.7. :/ 

I am on aftermarket cooling of course but id expect the stock to do a little better than that.

I've re-seated the heatsink and reapplied the CF2 paste a couple of months ago, which fixed the overheating problem at that time. I just read another thread that said Quad core CPUs tend to get quite hot anyway but yours seems pretty cool Raidur. They also suggest getting a more robust HSF and I have the tower case and loads of good circulation to fit it.

Having said that, these are my temps right now with ambient temp around 18C and only IE running:

Yeah they usually run pretty hot. Make sure you clean out the dust, that racks up the heat quickly. As far as split temps... mine have about a 5c spread. I don't think it is too much to worry about. It could be due to certain cores working harder than others. Currupted memory is another big causer of bsods. Run a mem test if you don't think it is due to overheating.

I've run MemTest twice and all is fine. I got the BSoD again just now and have all the details. Not sure whether to start a new thread with this but see what you make of it anyway:

0x0000008E (0xC000001D, 0xBD0AC45A, 0xB2A75A1C, 0x00000000)
nv4_disp.dll
base at BD012000
Datestamp 4ac001a1

I'm about to Google it but would appreciate your expertise (assuming you have some in this area too).

Nv4 disp is for your display drivers. It could be possible that your drivers got corrupted or your gpu is overheating. If raising your fanspeed and reinstalling your drivers doesn't help id google it up. :)

I came to the same conclusion. I googled it and it looks like display drivers or the registry. I found new drivers on the nVidia web-site and that seems to have done the trick. I also found one invalid registry entry and deleted that, just for good measure. After 3 1/2 hours on Far Cry2 last night it seems fine. Thanks for your help.

Yup. :) 

Game on!

Oh dear, just when you think it's safe to go back in the water. I got the 0x0000008E error last night but with no video driver reference, so I assumed it must be the registry alone. I scanned the registry for errors but it's clean (according to EasyCleaner from toniarts). Tonight I got a 0x0000007E BSoD and once again the nVidia dll file was mentioned. I'm starting to think this is a registry problem that my utility can't find, although there's obviously a video card aspect to it as well. Maybe I need to invest in a more robust cleaner?

I'll keep googling.
