Are you sure you are not referring to Prime 95 version 27.9? A version 29.7 does not seem to exist yet.

Version 27.9 did not use the newer AVX2 instructions.

Version 28.5 is the latest official version.

It might warm things up a little more than 27.9

Prime on stock intel cooler is fine, tested on my 3770k

The 4th Gen Haswells are in a league of their own when it comes to putting out heat. With a 4th Gen CPU and the latest Prime running Small FFTs, you are probably going to be getting very close to the thermal throttling temperature when using the Intel OEM cooler.

Yes, must have been 27.9. Probably typed it in wrong in my OCD-ish folder structure. It's great for finding and updating stuff though :-)

I'll give it a try under 28.5.



Also:
Temps = / = heat. The main problem with Haswell is heat transfer between die die and IHS. Heat production is expressed in Watts ( E_thermal/time), temperature is expressed in °C or °K.
Physics aside: the increased heat output from 28.5 will indeed raise temps.

+1, I reached around 95C on my 4770k with the latest Prime on intel stock cooler. I really doubt you guys only reach 80C with latest prime + stock cooler, that's way too low of a temp.

I tested with 27.9, so it might give a higher temp know. Yet, as stated before: if your (Intel) product (Haswell CPU) fails to run within spec, you have a serious design flaw. You can save on thing: internal TIM/soldering OR heatsink. But not both mad.gif

They have to. Your product is fundamentally defective. Well, I'd recommend telling them this: "You can replace my CPU now, and sell it to an other customer who isn't bothered by it. Or, you can let me run it @100°C on prime for a week and then replace it because it broke, within Intel specification, running their cooler and their clockspeed."

Give it a try. Hopefully they can pressure your shop for a quick RMA thumb.gif
