Dual core newby here? need some Q's answered

StevenG · 25 May 2006 at 11:13

if i run a program that uses 100% cpu (single core) does that automatically run on just 1 of my 2 cores? or do i need to change settings?

is there any decent dual core dvd encoding software similar to winAVI??

erm.. thats about it lol. loving the fact i can now multitask

I take it that you can see two cores in your task manager now??

Usually run 50% on each core. It'll be the same speed as a single core of identical CPU speed, but your dual core won't hog whilst you do other things. Or if you do want full 100% per core it'll be quicker. ie 11 minutes on 1 core 100%, 6 minutes for both cores at 100% for the same process.

what should my pwmic temp be?

Mine usually stays around 40C but yours may be different depending on your board and cooling.

have you got both cores coming up in task manager mate? there is a hotfix from microsoft if not

see it on the right side window, top right (cpu usage)

StevenG · 25 May 2006 at 19:36

yea got both cores and my pwmic temp is 58 lol but its been sunny all day and my windows were closed

StevenG · 25 May 2006 at 19:39

also... how long should i prime? im doing small fft's and both cores have passed all size's and it been going for about 7 hours

Mikey1280 · 25 May 2006 at 19:55

I would say prime for 12 hours, some say more some say less

StevenG · 25 May 2006 at 20:11

well the guy i bought it off said it was prime stable but didnt have a screenie. it seems fine tbh went straight in at 2.6

Just try one hour, most errors owuld ocme up by then

StevenG · 26 May 2006 at 10:36

did it for 23 hours or something with no errors. squiffy said that a program will use 50% on each core. mine isnt doing that. if i run a (single core) 100% program it used about 80-95% on the 2nd core and the rest on the first.

did u reinstall windows when u got the dual core cpu or was it a fresh install when u got it ?

idoru66 · 26 May 2006 at 12:28

How key is this fresh install? Seen it mentioned a few times now.... I didn't personally.

marcus_667 · 26 May 2006 at 13:54

well if windows was installed on a single core system and upgrading to a dual core you will need to re install so windows can install and recognise 2 cores, id get windows reinstalled

you dont need too.... you can change it in your device manager.... under 'computer' changing it to a 'multiprocessor PC'
