I just upgraded from an Athlon 64 X2 4600+ to a Phenom II X4 955. New CPU should be much faster, but instead it seems significantly slower.
I ran a few benchmark tests (Novabench, PCMark 7, and Vista's crappy little built-in index thingy) just before switching the CPU, then again right after. All three showed significantly lower results with the new core.
Can anyone tell me what could be causing this? I also installed a new DVD burner at the same time. It's hard to imagine how that could be responsible but I include it for the sake of completeness.
My system specs are:
Athlon 64 X2 4600+ (old CPU)
Phenom II X4 955 (new CPU)
MSI K9A2 CF-F Socket AM2+ ATX Motherboard MS-7388
Corsair TX 850 PSU
Corsair XMS2 DDR2 800 RAM
Radeon HD4870 GPU
WD2500AAJS 250Gb Hard Disk
ASUS drw-24b3st DVD burner (newly installed)
I'm running 32bit Vista, but I actually have a copy of Windows 7 I was about to install for the first time.
When I booted the comp. right after the new hardware it did take a long time to start up, which I assumed was the computer processing the new hardware, and when windows was up and running there was a "new hardware" message in the system tray that ran for a bit and then said everything was ready to use.
Please help, and ask for any further information needed.
EDIT: I have now tried resetting the Bios, to no avail.
