I have an e5200 on an Asus P5kpl-am board overclocked to 3260mhz.
Real Temp, CPU z and XP's system performance only show 1 core. Does anyone know how I can see the other core?
Resetting BIOS and CMOS doesn't fix the problem. MSconfig only gives the option for 1 processor.
There is no entry for multiprocessor in the BIOS, although I think I saw this in the HAL options on WIndows setup (press F5 when setup asks for 3rd party SCSI and raid support).
When I installed XP I set the HAL to ACPI and not Multiprocessor ACPI. Is this the reason why I cannot see 2 cores? Will this affect the performance of the CPU, i.e. is my 5200 running at half its potential?
Changed the HAL to Standard PC but other core didn't register (didn't have an option to change it to multiprocessor).
If there is no performance hit then I don't think I will do a reinstall of Windows. I've only just got it running as I want it after a lot of stability problems initially with this PC's setup.
I'm guessing that my chip isn't just running on one core?! If it is, its doing a pretty splendid job all on its own.
Just looked (ctrl-f) through the pdf of the manual, doesn't mention multi processor.
Which is really kind of stupid before the i7, because the Core 2 Quads can't actually disable the other cores, so disabling them will just prevent any work from being sent to them (but they'll still be on, just at idle). The i7 is different - it actually physically disables the cores that are shut off, and as a result, that strategy might work better.
