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

Offset voltage? Mind explaining?

It adds or removes from the stock voltage. So you don't input a voltage like 1.25. For example i have a minus offset at 0.050 and it'll remove that from the stock voltage. i think the stock voltage is like 1.22 so it would take the voltage down to about 1.17 at full load, that will scale as well if you have EIST and C-States enabled.

You have to be careful with offset voltage because I accidentally put 1.25v thinking I was changing the CPU voltage and it blew my i5 2500k as I wasnt concentrating and it was next to the offset.

Luckily it got replaced under Intel Warranty and my replacement was a later one which clocked like a beauty.

Hmm.. Okay, i'm going to read a bit more into it.

Yeah I definitely do not want to blow up my chip!!

Just have to triple check to make sure you've not goofed the voltage.

Managed to get my 4790k stable at 4.7Ghz with 1.226v. Seem to have got a pretty good clocker. Temps seem to hover around 68C.

Wow that's bad, i can get mine down to 1.175 at 4.6Ghz. I paid £250 for mine from a competitor, it would have cost £290 from OCUK.

I would say more yours is good rather than his being that bad.

Mines 4.5 at 1.236 and that is the lowest it will go. I can't go higher as I have a quiet fan in my itx case.

Messing around I found that I needed more than 1.3 for 4.7 and not far off for 4.6.

Ye, i'm not really sure what is considered an "average" chip. Mine seems to be pretty good, although i've seen a couple that are better than mine.

This is the first chip I haven't felt the need to overclock

Guys I just tried what a difference HyperThreading can make as well as overclocking the cpu in Crysis 3

Stunning outcome..

System used:
i7 4790k@stock and @5100MHz
2x8GB Corsair Dom Plat(Painted red ) 2400CL10
MSI 295X2@1150/1500MHz
Asus M7 Hero
Crysis 3@Max Settings

4.4GHz HT-OFF = 65fps (cores at 99%)

4.4GHz HT-ON = 82fps (cores at about 85%)

5.1GHz HT-OFF = 79fps (cores at 99%)

5.1GHz HT-ON = 93fps (cores at about 85%)

I feel the same. This will turbo to 4.4 anyway.

On one core.

My processor is wasted doing things like online banking then.

It's got an easy life, passively cooled on stock. LOL.

4790k for online banking? Oh dear.

Hi,

So decided to have a look at overclocking my new i7 and looking like this at the moment, does this look promising? Max temps were actually 84 degrees. Not sure why HW monitor is actually saying max clock is 4.6 when i have it set at 4.5?? All help/thoughts appreciated.

 

[setter]

Looks pretty ok, 84c max is actually pretty ok for burn test on one of theese. No idea on the multiplier issue though.

 

[Nedb37]

Thanks,

Just a thought, with the offset am i not actually at 1.3+ v and maybe not getting a decent clock for the voltage? Little new to all this so curious. Have a feeling offset was set to auto.

 

[Nedb37]

Just ran another test. Kept the same voltage and changed the multiplier to 46. Ran a 'high' intel burn test (passed) with CPUZ and HW Monitor running. CPUZ confirms 4.6, as does HW Monitor but, HW Monitor again has the 'Max Clock' above what i'm running (this time saying 4.7). It's probably something very obvious but, would love someone to explain it to me..

I own an i5 2500 non K, should I upgrade to this? I do a lot of video editing but also some gaming. Will get a 970 soon too.

It's not worth buying a new board and CPU if you can grab a used 2600k/2700k or 3770k and use that in place of the 2500.

My 4790k seems to be hitting 1.273v recently when any of the cores turbo to 4.4GHz (running stock). It used to top out at 1.263v and nothing has been changed in the BIOS. Could this be a sign of degradation? I'm also getting random freezes during web browsing, but I think it's more down to the Nvidia GPU drivers.

It's actually a cool running chip despite the high core voltages. It tops out around 58c when gaming using an Alpenföhn Matterhorn cooler along with Arctic MX-4 paste.
