Hey all., I have the p4p800-e deluxe board and have been running, for about 1.5yrs or so, a Celeron 2.0 OC'd to 2.6. Never a hiccup.
Long story short: wife left, took her machine, that my kid plays on when he comes over, (and she took the dog!!!!) and I am moving my machine (the Celeron) over to replace it. (Bought an AMD Dual core 5000+ to play with!) I have the p4p800-e in it, as I said, and it was running a Celeron 2.0 with a gig of kingston RAM and GeForce 6600 card. I want him to be able to play COD2, WOW, etc head to head with me, as we usually do. I bought a P4 3.0 Ghz chip to upgrade (I have BIOS 1009.003) the machine and squeeze out some more performance. Turns out CPU-Z identifies it as a Prescott (which I wouldnt have bought, if the ad had said so) but whatever...its in and running with Hyperthreading turned OFF in BIOS. I did this because when I first installed it, it ran fine for a while, and I even overclocked it on a practice boot to 3.9Ghz! I got a little nervous about heat and shut it off and set it back to 3.0. I played some COD and it rocked and even watched a movie for a while. Went to bed (machine ran overnight), woke up, the machine was frozen. I rebooted it and got B.S.O.D with some "bad_pool_error" problem. Couldnt reboot to desktop no matter what I did. SO.......I took chip out, put celery chip back in, ghosted most recent image and it booted up fine. No fried board or socket or whatever. I went and bought a new CPU fan/sink (rated to 3.6Ghz) and reinstalled the chip, then booted and went to BIOS and turned Hyperthreading OFF. Device Manager now reads "ACPI Uniprocessor PC" Been running a couple days now with no probs....BUT....its an HT chip with an HT capable mobo....what about hyperthreading? is there a driver I should install? I know XP will "detect" it on boot up, should I install driver FIRST and THEN reboot? whats up?
Soooo...what I need to know is: to enable Hyperthreading in BIOS, what do I do? What is safest course of action? Leave it alone? No hyperthreading?
Thanks for any info on this board/cpu combo.........................................................................................'boss
I have this board and a P4 Prescott 3.2GHz chip in one of my machines. It's been trouble free running with HT turned on, but I'm not a gamer, however I do use the machine for audio production and occasional video editing which is demanding of the CPU and makes use of HT quite extensively.
The problem you appear to have is that the version of the Hardware Abstraction Layer (HAL) that is currently installed in your installation of Windows XP is for ACPI Uniprocessor, and this will be because either you had HT turned off in BIOS in the first place and/or your Celeron doesn't support HT. In short you need to repair or reinstall Windows with the correct HAL in place and with HT enabled in the BIOS. The easiest option would be to simply repair the current installation and this should leave all your program installations etc... intact, however the most satisfactory result in terms of performance and minimising problems potentially left behind from the current installation is likely to be achieved by doing a completely clean installation of Windows, which of course is more long winded.
The correct HAL will show you ACPI Multiprocessor PC.
If the system was reasonably trouble free with the Celeron, then a repair is well worth attempting.
In any event, make a backup of any important data first.
