Nice try. But I can see that you are using an older Prime95 which doesn't really stress the Haswell to the correct level.
Pls use the latest Prime95 27.9 posted in the first post of this thread, which has AVX library.

Guys, im stuck at 4.1Ghz..
maybe my RAM prob? im using Kingston hyper x KHX1866c9D3K2/8GX

my mobo is maximus vi extreme, i74770k, noctua NH-D41,

Please help..

i knew this was going to happen with ppl buying the m6e and hoping plug and play and oc.

the bios aint ready for that.

tested occt linx. it works with avx. interesting part sandy each run was about a min before the cool/heat. this was doing it every 15-20secs.

wish could see the glops.

what is the symptom? Unable to post or stuck at Windows logon screen?
The most suspected cause is insufficient vCore. Try upping it slightly to 1.1v etc.

Im using V6GT with corsair SP120 Perfromance fan and its awesome. i tried with noctua premium nf12..still didnt perform well. H100i?? out of the league. but im interested with ur thermalright. mybe i wanna get soon and try on.

Noted. will download and try.

whenever i try to hit more then 4.1Ghz its will crash after is test is using prime95.. Even by using Asus AI Suites,same thing happen.
but the cpu temps was around 65-70.

So now you know... .

Thats actually a very ineffecient fan. Loud at 2k rpm. Get some mp12.

i dont mind at 2k rpm loud, but actually its not that loud, i still can hear my keyboard tap. for me as long it can fast and better flow is enough already. what do you think of noctua cpu cooler?

well i tested silverarrow sb-e extreme which is better than the noctua and still couldnt beat my thermalright ultra venomous x.

the problem with haswell is not transfering enough heat to the pipes and fins with the small die size.

heatsink base material is what we need here.

so got a feeling kryos silver that cost a bomb is going to be excellent for haswell.

Guys.. I just oc-ed my i5 to 4.5ghz at 1.2v. Running IBT now. What's the best setting for IBT? Running it at very high now. And my temps so far is 75c max.

Use latest occt 90% available mem with avx

lots of sifu here I shall need your guidance once I get my hands on haswell

Anyways just sharing a good guide from JJ...might help those newcomers too

OK got 1.6v at 0.85v VSSA stable with the lowest timings etc. Awesome read/write/copy



Still a few more timings to finish but lol after 6 hours kindda tired.

Thats awesome dude....

I also join the fun...

whoa...81!...on air cooler?

Yes! Air cooler.. stock fan... that's why 81C!

Any one can recommend me a good CPU fan?

Ure throttling.
Use a all in one water cooler like h80i or h100 etc. n in ure case use ram slot 1 n 3.

Reason for that cooler is because of the ram slots.

U can clock ram slot 2,4 but much harder to do that.
