post #1211 of 19539
What stress tst are you guys using ive seen and heard that prime95 and couple others can and will cause random freezes which will indicate a false bad overclock.

Imo a lot of people should start with intel's extreme tuning utility. Also you can try aidia64 however imo with this chip ive had best results with intels stress test...the teps get the same as aida64 but more stable and I haven't crashed yet after using intels extreme tuner. thumb.gif

as long as ur not crushing some ridic uncore multi than intels stress test is all you need imo.

I don't understand why core 1 is always high than all of those core. is there anyway I can fix this core to be almost the same temp ornot?

how to make temp to be almost the same?

And this is my stable OC, anything below is BSODING.



Is there any chance to get it higher?[/quote]

I have that board! biggrin.gif depends on your chip and your temps when stress testing. I'm currently at 4.5GHz stable using


I'm testing this right now. Thanks for the numbers. biggrin.gif I was stuck at 4.4GHz, and testing with prime95 currently on my 4670k. Looks like I'll be delidding soon though... I don't like high temps. =/ I've only hit 77C so far, but I"m sure it'll go up. Granted, that's also max, I'm holding around 70-73C One core is actually running at 61C occasionally. I wish they were all that low. tongue.gif For some reason, Core #3 seems to stay a good 5-7C cooler at all times when under load.
It'd probably help if I wasn't lazy and would reapply my AS5. I had to use some crappy coolermaster TIM I had laying around because I couldn't find my AS5. Ordered more, and then found it. (Story of my life)

Try out these settings, they worked for me! Prime stable after 10h stress test. Hit 80C at some point during the night. Also, rep him if it worked for you, because he's awesome

Try this,,,
45ghz Core clock 1.325v
40ghz uncore 1.21v

Vccin/Vrin input voltage of 1.95v try this first u can lower later to maybe 1.9
Vccsa needs to be increased if running ram past specs...off set to maybe around 0.150-0.175

Edit: because I her derps

i also have a 10C delta between the hottest core and the coolest core.

delidding is the only solution.

it is already delidded. it is sill the same.

delidding is the only solution.

There's also simply the fact that the four cores are in a row and the first has the cold iGPU beside it, while the next two will have the other hot running cores left and right if you use a stress test. The last core has things like memory controller beside it.

I guess cause last core is always the lowest of all 4 cores. then core 0 is lower than core 1. core 1 and 2 almost about the same .

I think I would stay 4.2 at 1.25. Going to 4.4 at 1.32 it's not worth it at all. The performance gain is not equal to voltage bump.

I'm at 4.5 with 1.32. I'm sure I might be able to lower it a little, I just am doing the method of going down in voltage to find the most stable versus building up. Not to mention I'm only hitting 80C on one core with my current cooling solution.

I am below 70*C at 1.25 when stressing in prime95 so I have the room for further OC, but I do not know it is safe for haswell to go with volts to the range 1.3 - 1.4.
