Install AMD dual core

[Mercutio]

I think im missing something - I took my 3700+ out (of an SN25P with latest bios). Inserted a 3800 X2 dual core, reset bios and loaded failsafes just to be on the safe side, booted into windows and nothing. No dual core.

Downloaded the AMD dual core driver and the clock watcher util, installed the driver, rebooted. Still no dual core and the clock watcher util is also only reporting a single core available.

Anyone any idea whats going on? I had a poke around on various sites and they all seem to have it as: 1) Insert the chip. 2) Boot into windows. 3) Enjoy dual core.

Any ideas would be highly appreciated. As a question would a fresh install of windows ever be needed for the upgrade?

Occasionally a fresh install is needed.

I just needed a couple of reboots, and re-installing AMD CPU driver (went from 3700 to 4200x2)

Try deleting uniprocessor from device manager/computer and reboot.

Windows & BIOS up-to-date?

BIOS up-to-date?

Shouldn't need to do that, if the BIOS detects a dual core CPU then no need to reflash. Just need Windows to re-detect CPU. On mine it just came up with the "finding new hardware" in taskbar, and after a short while requested reboot. Two cores in task manager and device manager 4200x2 showed it was working

Ill try the above about playing in device manager - didnt really consider that. Bios picks it up as an X2 so that one I should be able to rule out. The installs a little flakey anyway so I might just take the opportunity to flatten it and start over. Cheers guys

Well device manager has both cores shown but the AMD tool still doesnt and taskmanager still doesnt so i guess thats looking like a re-install?

What is task manager showing, in the performance tab, one section for a core or two?

Are all ACPI options enabled in BIOS? I was trying out Linux which doesn't like ACPI, forgot to re-enable it, when I installed Windows it didn't detect the dual core.

As above - only the one

Well... ACPI function is turned on in bios, turned off a lot of the "wake up if i cough and tap the table twice" type options. I dont see anything there that id want on (hdd spindown time, soft-off setting and the aforementioned power up if i prod you with a banana). But its definitely enabled

Finally got a day off tmro so ill likely get a re-install done, looks likely to be easiest way to sort it.

Well.... reinstalled and all now fixed, no idea what was up but its all sweet now

As a final bit to this any tips about making the most of dual core for gaming (games that arent dual processor aware)?
Can you set certain processes to run on certain cores or set games etc to run in just the second core so the windows overheads arent on the same core?

Just install amd cpu driver. No need to mess around with affinity- windows will do it.
