Single Core

[Nick_Black]

ok, I've posted a thread a while ago about my computer freezing, and I think I know the problem.. I believe it'll freze avry time it try's using both core's in my pentium "D" is there A way to make the motherboard only register the processor as a single core (or thrue the OS)

No.

Have you tested your memory? Google Memtest86, download it (it's free), put it on a floppy disk, and boot the computer with the disk in. Should launch itself automatically, and if you have errors then you know where it's from.

Besides, when does your computer crashes? because when you use such a processor (dual-core), it ALWAYS uses the two cores. Even while loading Windows.

yes I did check the RAM (I let it run for 20hrs) and there was no problems.
I find the probalems occur when I'm using 2 or more bandwith sucking app's (like limewire and msn, or youtube andonline update, ar anything like that) and I thought (reading reviews and sutch) that pentium D alway's ran on single core untill the app was capable of using Dual (due to it's lack of hyper threading) but I could be wrong, anyway's, Thanks for the reply!

If it happens when you use power hungry apps., then you may have inadequate cooling. Are you OC'd? What are you using for CPU cooling? What are you using for case cooling? What are you using for RAM cooling? Heatsinks, fans, none of the above?

May also be a lack of power from your PSU. PEntium D's are power-consuming systems, and if your system is overclocked it maybe the cause.

If you want a proof of what Ive said, just hit Ctrl-Alt-Del to get tot the Task Manager, and look under the PErformance tab, you'll see two graphs for the CPU, these are your two cores.

As far as I know, Pentium D's always uses both cores... or maybe I'm mixing it with Hyper-Threading?

You could also download a diagnostic software from your HDD's company website, and run it to see if you have any bad sectors. Bad clusters can cause lock-ups, BSODs and stuff like that.

as far as i know if its a dual core proc. its gonna use 2 cores, it has nothing to do with what or how many apps you are running its just how the processor works. what you may have been thinking of is a 64bit processor which requires programs to use a 64bit instruction set to work to its full potential.

i would look elsewhere for the problem as said in previous posts. also when you say your computer is "freezing" do you mean locking up so you have to restart it or crashing and restarting on its own?

Just remember, if it is not a dual core capable program, it will just run on one of the cores. You shouldn't have any problems with there being 2 cores.
It's probably a power or heat problem as the above guys said.

are you BSODing? or is it just turning off and rebooting?

if its the latter, its heat/power
