CPU upgrade problems.

Liqourice · Oct 11, 2008, 02:56 PM

I've upgraded my 5200+ to a Phenom 9850BE and I have a few issues.

First of all I know I should reformat and install windows from scratch but I prefer not to so I'm trying to get everything to work first with the old installation.

Before the switch I uninstalled the cpu drivers, the dual-core optimiser and AOD.

After the switch I reset CMOS and set all settings in BIOS to auto to begin with. Booted up, installed cpu drivers and re-installed chipset drivers.

After that I've experienced a few things. First of all the computer suddenly reboots, even if all settings are at stock and on auto. No BSOD, it just plainly reboots.

It MIGHT have to do with CNQ. I've never ever had that enabled before, I've always disabled that in bios but I thought I was gonna try it and see how it worked. I've now disabled CNQ to see if the rebooting stops.

Second is CPU temperature. With my old 5200+ it was at 35C when idle at maximum overclock. Now this Phenom is at 43C when idle at stock clocks. It sounds a bit much. I use the same cooler, a Zalman CNPS9700 (or 9500, I don't remember for sure). Don't know if the layer of cooling paste I put on was to thin, I made it as thin as I possibly could. At load it goes up to about 55 on stock speed.

A quick OC in AOD from 2.5 to 2.9GHz and the idle temp goes up to 48 and load temp close to 60.

what was the room temperature where the computer is located?

Room temp is about 24-25.

I think I nailed the crashing issue. Twice after it rebooted it claimed to have found the soundcard as new hardware. So, I rebooted again so it was detected as normal and then installed the soundcard driver again. Now it's run for 13 hours straight so it seems that the soundcard driver was the cause of those reboots.

I've made a few attempts at overclocking and found one really strange thing.

When I lowered the memory speed to 800 instead of 1066 and raised both multiplier and FSB the temperature at idle suddenly showed 5 degrees lower than with everything at stock. If I OC with just raising multiplier and voltage the temp rose 5 degrees at idle. The latter is logical, the former is not so I suspect something is not right.

Well the memory controller resides inside the CPU so it might make a difference, but such a large one certainly seems wrong. Maybe when the CPU cores are in Cool&Quiet mode the memory controller still has to run at full speed or something. On the other hand the CPU temperature probes are also specifically designed to measure full load temperatures fairly correctly and are much less precise at low temps. On top of that I wouldn't care much at all about other tempeatures than high to full load, as low load temps are of little practical importance.

CNQ is not activated so it can't have anything to do with that.

But the high temp during load shows 5 degrees less as well.
