hi.
couldnt find any straight comparrison between the 945 and E2140 but would like to hear ur thoughts on the differences between the two, thanks! btw im fairly cirtain my specs arent up for any decent (if any) OC of my 805.
"im fairly cirtain my specs arent up for any decent (if any) OC of my 805"
From what I've read, the Pentium D 805 is a monster overclocker...clock speeds of well over 3.0GHz are "normal". For example, 3.33GHz (20 x 166MHz) *should* be easily attainable. Of course, you'd have to have a decent motherboard/RAM/PSU & some overclocking knowledge to be able to do it. We have no idea what you have or what you're capable of....
Regardless, the Core 2 Duo is better. You can't directly compare a P4 & C2D based on clock speed.

Core 2 duo's are 2 to 3x better overall then the Pentium D's that it repleaced.
A Core 2 Duo E6300 @ 1.86ghz can smack around a Pentium D @ 3ghz. so like jam is saying you can't compare a Pentuim D to a Core 2 duo in clock speed.

pfff... i know clock speed means squat compared to the architecture of the cpu. but for a definitive answer.. the core 2 E2140 would beat the 945 in most comparrisons?
and.. yeh.. i prob should have read a bit before buyin the mobo and ram i have as i only realised later (i think from u jam!) that the asrock 775dual vsta is hopeless for OC'ing a cpu. but on another note, is generic ram ANY good for an OC? thanks

Your board is a budget board, but it is overclockable. A CPU Freq of 300MHz *should* be possible:

jam.. u always come through!, thanks mate i had almost given up hope on OC'n my rig, cheers!
'edge out'? u mean just a slight advantage over the 945? thanks

Yes it's slightly better. But if you overclocked that Core 2 Duo version to just 200mhz faster it would outbenchmark it in all the test if not by a nice sum.

LOL.. awww man i feel like a noob.. i only just realised i could OC that easily hahaha aww.. good man jam!
ive started slow and moved the freq from 133 to 150 and the temp seems stable at 49/120.
so wat is an acceptable temp for an OC'd cpu and any suggestions for wat freq i should just go for?

49C for a Pentium D is normal. No worries there. Yet.
I have seen Pentium Ds idle at that temp (hot room temps dont help), so if yours is 49C o/c at load, then it is absolutely fine.
Have you tried pushing the CPU Freq further? I dont think you will need a V core increase if you try 160MHz, but do that in steps. Say, at 155MHz, run a stress test and if all's fine, then proceed further.
Btw, I presume you are looking at a CPU upgrade only, right? What do you intended to use the PC for?
That can answer your question of which CPU is better, if at all you need an upgrade. Unless you are into games or very serious multimedia work, the 805 with some overclock will serve you well. You can certainly use more RAM for those purposes for the same amount of money.

umm not sure my mobo allows a change to the v core. money does get tight for me these days so the only soon to come upgrade i think i will be making is a gig of generic ddr2 ram and the best OC i can get from my 805 with stock cooling. as for games and multimedia the only game i play is CS:Source and i do a bit of photo/video editing for school. i'm just keen on a faster rig pretty much.
wat kind of stress test do you mean btw?, is there a certain app anyone would recommend?
aww and i tried it at 160, didnt boot.. 155, boot but soon restarted. so im currently at 153 which is giving me a clock of 3061.1Mhz on cpuz.
so how should i stress test this? thanks
0
ahh just found a test called 'CPU Stability test' and it says it will do a 5 min HEATup test. how long should i let it test? thanks

I can see why jam is LOLing over the '5 minutes'. People like him run the test for something like 5 hours or even 24 hours (I stop at a couple of hours).
use prime95+ for dual cores (it is in Beta) or just prime95 and run two instances of it. Do that for at least an hour.
3GHz is not a bad speed at all, even on an unoptimized CPU such as this one.
From what you have said about your usage, you dont need a CPU upgrade right away. Get more RAM, as much as you can afford and you will be fine.

Try Stress Prime 2004 (which is based on Prime95) instead. This version is for dual core CPUs:
