Out of the two programs which one do you like better & why? I"m curious b/c on Prime95 I seem to be able to run it for hours @ lower temps...mid 50sC..yet with Orthos my temps his 60C. Whats the difference?

Thx,
Main

I liked Prime95 back in the Single/Dual Core days, but I use OCCT now. Works great, multiple core support, gives OC statistics on the cpu and mobo, and also gives temp readings (including nb /sb/hdds/gpu/etc).

Never used Orthos, but heard a lot about it.

are you using the same temp monitoring program?

also what test are you using on both ?

mostly cpu torture test on prime95 & the first one with Orthos - temp progs are pc probe & speed fan - hw monitor - core temp - only pc probe/speed fan/hw monitor is right thou

if its between the two orthos stresses your cpu more , if you pass orthos you will definately pass prime95 but not nessesarily vice versa.

But I wonder how much would another program..or typical usage stress the cpu? I can run most anything..the other thing that throws up my temps are doom3 & orthos..confuses me lol

which one the small FFTs is the one that just loads the cpu and gets it the hottest

i like to use blend to make sure the mems good ;)

Yep thats the one..small ffts

yep , small FFTs is a real bugger for your cpu, if ur CPU can last em out, then its almost bullet proof.

So far i havnt seen any game or daily use program what so ever that makes my cpu cores as hot as orthos.

update- I have just downloaded OCCT and running it, it seems as good as orthos.

Temp wise, it seams OCCT get's hotter then Prime95, in my case. I was totally surprised by that :eek:

The prog used to monitor temps with both progs was Real Temp 2.5.

yeps it seems to be stressing as much as orthos with small FFTs

About stressing, i don't really know. What i do know is that my PC isn't able to run a "big" prog (game, encoding and such) for about 5 or 6 minutes after ending a priming session. The same isn't true for either Orthos or OCCT. I was told this was because of Vista, but i don't really know!

hmm, thats strange. Prime95 isnt supposed to be running after exit as far as i know.

BTW - Hugo u do know that u can push ur cpu up to 3.6ghz on stock cooling and voltage easily. i ran mine like that for a long time till i bought another heatsink and then took it to 3.8ghz

I'm running my 5000+ black @ 1.45volts @ 3200 with like a mult of 14 & fsb @ 222 - temps on this run high with the previous mentioned game & orthos..it's a killer - my question is how far can I take max temps..b/c pc probe showd me hitting 60C - dropping 2 around 58C - hitting it again..etc. Can I trust this?

I think it's something related to the HDD: it's heavily working after stopping Prime.

Better not. I lapped the CPU pretty good and the stock cooler as best i could (push pins in the way :shadedshu) which got me a 9º reduction but it still gets 70º in Prime95 and 72º in OCCT.

I only go higher for benching. Have had it @ 3.85 but 3D06 crashes if i OC the graph card: without OCing the graph card, Real temp reports 76º as highest after a 3D06 run and that's a bit too high for my liking :(

funny i could run at 3.6 on stock without lapping and max temps were 66 C (then again i have good airflow in my case).
Now at 3.8Ghz @ 1.5vcore i get maximum core temps at 69 C.

Also Realtemp was not accurate(always 7-10 c higher) both Coretemp, Speedfan (latest version) and OCCT show exactly same temps so i trust that value.

Dunno about that: this (http://maxpoint.de/de/gfx/products/cases/TwinEngine_BB/Twin_Engine_BB_Uk.pdf) (PDF file) is my case.

Also, regarding the temps difference, OCCT reports higher then Real Temp 2.5 by 4 or 5 degrees.

Back on topic, IMHO, Prime95 is best to test the system: if your system passes 24 hours, it's rock solid!
