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

I have just bought a I7 4790K chip. I increased the multiplier to 4.6 and its stable under a Antec Kúhler H2O 1250 Liquid CPU Cooler and a MSI Krait board.

Should I leave it at that, or can anyone recommend other BIOS setting(s) I should alter?
 
4.5 at 1.14v is the lowest i can go while staying stable. Pretty happy so far, much reduced voltage from 1.2 and max temps under 80 now.

Interested to know who is on air (as i am) or water.
 
Megahalems with SP120 in push/pull here. I've been getting 84c on 4.5 @ 1.2v .... Might take a look at reseating the cooler and see if I get any improvement.
 
I was using a Corsair H100i on my 4790k, temps were ok but the pump on the H100 has died within 5 months of owning it.

Looking at going back to air cooling and was looking at the Phantek PH-TC14PE cooler to replace it. I am guessing on air I will see a rise in temps maybe on the overclock, but then again, the H100i would sit with a water temp of around 32c half the time so was never cool in the first place.
 
Hey guys, i7 4790k on it's way, to be put on a MSI Z97 Gaming board :) It has been a good few years now since I've built my own system, yes I did the i5. However my question is with these new cpu's and boards, is it still a simple case of putting in the cpu-thermal paste-cooler turning on?

Had my 4790k chip a week but getting the same board (5 version} and new psu end of week. Did you buy an aftermarket cooler? What's good for overclocking?

Supposed to be as good as the Corsair H100, however there are a few reports of early cracked blocks. But as with any product, there is always a risk of a fault.

Pretty much yep, once you get it all up and running, make sure you have the latest bios for the motherboard installed. Early versions tend to overvolt these chips a fair bit. Not a good thing on a chip that already runs quite hot.

Pretty much, yes. I'd see if there are any new drivers you need but any new bios are probably to cover broadwell and you won't necessarily need them. I'd do the OC yourself though, heard mixed things regarding the MSI OC genie.

I have an MSI gaming 5 I need to sell, actually. Shame I don't have access to the MM.

Ah really? I'm still on the Asus 2012 bios, when I checked for an update, they only seemed to be an update for broadwell. You think it's worth trying to update?

Which board do you have? For my one in sig bios 1505 was the one needed as the first one for the 4790k, (1504) had the voltage issue. But mine is an older Z87 board. Id say the last one released prior to the broadwell compatible revision will be the most suitable.
 
Max VII Hero, think the 2012 bios are from October last year. From memory, latest ones were pretty much a 5th Gen update and not necessarily improved stability. Probably won't gain anything.
 
I have been playing with my chip too.
4.8GHZ at 1.3 v core and it appears stable on real bench at max temp of 71'c under an EK evo supremacy block, it will post at 4.9 but not yet stable.
 
Looking at the below results do you reckon its my lowly R9 270x that's killing my score?

No as Realbench tests the CPU not really the GPU. So if you think your score is low then you would look at improving your CPU first. The GPU test doesnt count to the final score as much as the Editing/Encoding/Multitasking scores. I've seen your OpenCL score better some PC's with a GTX 780.

eg GTX 780 with i7 2600k
