Intel 4790K OC Report ~

[Splave]

here is 5.4 on air ASRock z97 OCF :P

wtf? voltage?

Hi Splave,

What is the maximum CPU frequency you can achieve running 3DMark06 at 4/8 on air with that board.

Please let me know, I am thinking about pre-ordering this board on the Egg.

Thanks!

[Splave]

5.1ghz XTU on air

[solofly]

1.55 volts, wow...

[flesheatinvirus]

That is simply sweet Splave, nice chip. Seems the IMC are much better then many other chips. Assrock boards certainly help the situation as well.

[sin0822]

I asked intel about the IMC, they said no change.

[i found nemo]

good to see you shredding it up fugger! enjoying the thread.

[LagunaX]

Nice thread Fugger!

Can't wait for the retail posts to start showing up.

BTW staying in Vegas on the strip this weekend for free thru my Hyatt card as they partner with MGM hotels

Anyone knows if the D0 stepping is for mobile only?

[Leeghoofd]

We got 4 ES CPUs for the team, 3 of them do 5GHZ 32M around 1.37-1.38Vcore on H80/100, one CPU has issues at 5Ghz 1.4Vcore... Seems these ESses are far better then the ones at the Computex competitions

[Dumo]

Are they 2014 batches Leeghoofd?

[Charles Wirth]

I picked up a retail today, testing now.

Resetting and results in a few hours.

[Metroid]

Thanks for the tests, interesting to see how the cold bugs happened. I had similar results.

Hello there. I have a question. I'm going to buy 4790K at NewEgg. Should I remove IHS and change thermal grease immediately after buying or should I try to get 5GHz on original one ? Will be using Corsair Hydro H100i with some hi-end thermal grease. BTW. What's 4790K IHS made of (material) ? Gonna be using some Arctic Silver 5 or maybe even Coollaboratory Liquid Pro.

Forget all about 5GHz daily stability on air or water... aim for +4.6Ghz, that would be a more realistic goal... unless you find a real gem CPU

[Charles Wirth]

I agree, for daily driver 4.6Ghz is better target.

Okay, but... 4,6GHz in normal mode, non-turbo ? ;>

[PatRaceTin]

I see some rich people buy 10 box finding best one and sell others.
(may be he sell them all)

You can see full scaling for G3258 L336D081 and 4790K L333C247 here.

Both scale up to ~-128 oC

[Charles Wirth]

Scaling on the 4690K is the same, my retail is better than the 4790K ES sample. I think the 4690K is priced a little bit too high for the reduced cache and lack of HT.

The retail 4790K I tested was a 6Ghz chip and the memory controller was far better than the CPU cores. I should have kept that chip.

The G3258 I tested was a dud, it would not break 5.7Ghz and cold bugged at -110c

Thanks Monstru

[Bun-Bun]

Hello all. Thought I would share my results with my 4790k. This is 24/7 OC on air.





Little disappointed. But at least I was able to keep the 4.5GHz I was running on my 2600K.

[Monstru]

My pleasure Charles. I Hope it helps people better understand DC and G3258

4800mhz_1.30V/cpu + 4600mhz_1.31v/cache (1.95V vccin under load)

Super stable, aida64 stability test 7hours.
occt:cpu_large data set = 1hour stable
occt:linpack = 1hour stable
Cinebench loop,xtu bench, aida64 benches, pc and 3d marks..etc..
All this with 70-85C max(delided cpu). No crashes/freezes whatsoever...

Now, the problem is 4900Mhz. Cant get it stable even with 1.4V. Thats 0.1V increase but only 100mhz gain..
Tried vccin 2.02 under load and didnt help.... Can run aida64 stability test for hours, can do XTU for hours too, can do cinebench loops, wprime 1024M etc... But in occt:cpu it crashes to bsod in 5 mins.

Any ideas ?
