***Intel i7 4790K Owners thread***

Looking to buy one of these at the end of the month. Any batches worth hunting for or has everyone just pretty much bought thiers new and hoped for the best? My 2500k isn't great so after a nice chip.

Yea did see it. If you still have it come end of the month might make you a offer. Is it 100% stable at 5.1?

I don't know about 100% stable it would need more voltage than I put into it at 5150GHz and you would then need good cooling, I do not like them to go above 80c.

What I have done is to look at what other peoples CPU's have done and mine is on the mark of the best I have seen.

The day I took it out and put the 4770K in the motherboard died so it will be weeks until I can try anything again.
 
Finally, my beauty is plugged in and fully fitted with fans :cool:

Mora 3 420 + 8x230mm Bitfenix Spectre Pro Red Led, push-pull

Cools my 4790k incredibly!

Water temp(temp#1):22C (deltaT=3C)
Idle CPU: 25-27C
Load CPU: 73-80C(Prime95_v28.5, 5G_1.36v, 2mins just for quick showcase of temps)

Ring, (cache voltage on my board) seems to be rather high when left on auto, reading as 1.28v. And cache is currently at stock of 4000mhz.

 
Don't leave it on auto. It may show high now but when testing it can vary allot and create instability. Fix it at 1.2v or if you prefer decrease the frequency of the cache to 3000mhz and test the stability of the CPU.

When you get to a good frequency and stable you can then start increasing the cache frequency...
 
Been running the oc in the screenshot above for months now, (4.7ghz). Mainly gaming were its been rock solid but various benchmarks too. Never bothered much with cache clocking on this chip aside from a few bench runs, previously had a 4770k at 4.5ghz with cache at 4300mhz. Chip wasnt a great clocker tbh.

The cache is more important in terms of stability, and what a difference it makes... You won't notice any difference by overclocking it

Ill have a look into setting it manually, tbh i havent tweaked this chip an awful lot. Went straight in a 4.7 on 1.300v, 1.800 on input. Could maybe run lower voltage or higher core speed. Bit of a quick n dirty oc. This seems to be a better chip than the first 4790k i had though. For testing the current clock my main stability program was asus real bench.

I hope you succeeded m8.

Thanks but same as before...bsod after 5 mins of AIDA.

I'll try what you said above and knock the cache down and see what happens.

The only other thing I've not tried is manually entering ram timings...well I have but the pc wouldn't boot.

Is that likely to help at all?

Cheers.
 
Changed my Tim from MX4 to Gelid GC Extreme, pretty decent temp drop. CPU @ 4.8ghz 1.28v

Appears I have one slightly warm core and one thats noticably cooler, guessing it's probably due to the IHS compound variation. Also noticed the image and encoding score on the Gelid run is higher as it maintained the max OC instead of fluctuating so much.

Did you remember to set the ram voltage also? Mine auto sets to 1.5 when i do it manually, gotta set it to 1.65 gain or i get system hangs.
