I upgraded my phenom quad core 2.2ghz processor to a 3.2ghz Phenom X4 955. The device manager shows all four cores and the system properties recorgnise the CPU as 3.2ghz. Also when the computer loads up it states 3.2 as does the CPU-Z utility. Unfortunately however I have seen no increase in performance after this significant upgrade- it's as if I've got the old chip in still.
I have tried turning off the 'cool and quiet' setting. Prior to installing the CPU I updated the BIOS to 1.5 as instructed on the website of my motherboard manufacturer. The bios shows as 1.5 when it loads up.
My motherboard is fairly old but it lists that it supports the processor in the support list. However this list is a bit confusing as I am a novice. The motherboard is an ASROCK K10N78hSLI-GLAN
Here is a link to the motherboard http://www.asrock.com/mb/overv...Model=K10N78hSLI-GLAN
The temperature of the CPU is running at 42 degrees and the CPU fan at around 4200 rpm - is this normal?
I am running windows xp SP3. Please tell me if you need any other information to diagnose the problem.
I have read that an reinstall of windows might work. This would be an absolute last resort for me as it would take many hours to reinstall all the software.
Thank you in advance for any help you can give me.
