Temp Difference btw Folding & Prime Blend on CPU??

post #1 of 3
Thread Starter 
Heyuys,

Quick Question:

Anyone know the temp difference you see on Folding and Prime Blend on a CPU?

I know there is acouple degree difference I am just wondering what the average is.. I think its about 3c..

Running Max 81c on Prime Blend. Hoping after I install Linux on it and start folding the temp would drop acouple degrees so I woudnt ave to worry as much running that high..

Also does anyone know how folding SMP compares to the level of stress put on the RAM during prime blend? More or less?

Thanks!

I've been up to my eyes in prime blends in the last little while and from what I can tell it looks to be about 2-3C but probably not any higher. Of course you need to keep in mind that my margin of error is probably close to 2C as well based on varying ambients etc, but from what I can tell Prime blend max looks to be about 2-3C higher than folding max. I would guesstimate that prime would stress the RAM slightly harder as well but if you error out in Prime then I would assume you would also error in folding as well. I shoot for 40 hours prime blend with as much RAM usage as possible for my rigs that I want to fold 24/7.

If you need some advice for tweaking check out the sandy stable club, lots of good inof there. Have you tried playing with different PLL settings? On one of my chips I attained stability with 10mV less vcore by changing PLL from auto (1.8v) to 1.65v. It takes a long time to test out all the possible options though, what I do is set up an OC that is borderline stable, something that fails prime in about 30-60 minutes, then run prime with every PLL voltage from 1.5 up to 1.8 in 25mV increments and see what holds prime the longest. I use the 1344 and 1792 packets or WUs or whatever they are called in prime for testing the trial and error of PLL.

I appreciate the post. Its basically what i was seeing as well. With a slight crack in the window i see a 2c drop and with folding max 2-3c less i can live with a 24/7 temp of 75-76c. Its not idle but for how quiet the rig is running its worth it.

As for the overclock i am fairly certain its stable. Ive spend a decent amount of time overclocking 2600k chips in the last 2 monthes and the sweet spot for pll seems to be between 1.55 and 1.65v. However i dont know have the luxury of fine tuning the oc. 1.445 isnt as idle as id like for 4.8 but anything else and it seems to bsod.. not an amazing overclocker if you ask me since i have another chip that oc to 4.9 with 1.435v... thanks tho!
