Dual Core CPU

Racingralph · 29 Jun 2006 at 23:52

Hi,

I've just installed my new DFI Ultra-D and HIS X1900XT but my dual core CPU doesn't appear to have been recognised as a dual core. CPU-Z and task manager don't display both cores either. I've tried a couple of the DFI BIOS with no luck, is there something obvious that I'm missing - can't see anything in the BIOS itself

Help please?

You need a driver...

See this thread....
Direct link in a post.

EDIT: Hang on a bit, I'm not sure that's it...I will edit my post.

OK 2 links for you...How to install a dual-core processor from AMD.

Much the same here from OCUK.

tried the x2 drive from amd - no luck. Any ideas

Well I edited my post for one...did you read it?

Also make sure you are using the version of CPUZ that supports 2 CPUs.

Esp the AMD link...

Install the XP SP2 Dual-Core Hotfix
Download the hotfix here.

tried all stuff from amd website. all drivers and bios are latest. amd cpuinfo software only sees 1 core - have i blown a core? 3d mark, task manager, cpu-z (latest) all see only 1 core. Only device manager / hardware / processor sees both cores.

Not sure why this is, all sortware is the latest and iv tried all of the hotfixes and drivers from amd - help?

Have you totally cleared the CMOS etc after restoring defaults?

Also try AMD CPUInfo as apparently that shows 2 cores running.

yep done all that - no good. amdinfo only shows 1 core. cpu was fine in the MSI board I changed yesterday. The only way I can prove it is ok is to build up my old pc with the other mobo which worked fine

Does the BIOS detect two cores? You could try a fresh install on a spare blank HD...then try CPU-Z, if it shows 2 cores then existing install isn't detecting the second core. I didn't need the driver for task manager to show two CPU graphs

just thought what it might be, installed windows afresh after build BEFORE I updated the BIOS. It would not finish the windows installation until I had updated the bios so I flashed the bios, booted and then it completed - that must be it.

Will install windows afresh tonight and hope for the best - dyu think that is the problem?

If you mean you stopped the windows installation, I imagine it could give you no end of grief.

Latest BIOS and fresh install may well be the way to go.

no, after setup copied the files and it automatically reboots the machine it would not fire up to complete the installation until I had flashed the bios - I didn't manually stop it. Once it rebooted after the bios update the setup continued automaically.

Will try installing again later.

I couldn't find anywhere in the bios that gave the usual system information or something similar. On the MSI Neo2 it was under system information and it told you what cpu and memory was detected - dyu know where I can find this in the bios?

Cheers.
