4790k Overclock

krustykobb · 7 Mar 2015 at 17:43

I'm trying to overclock my 4790k to a frequency of around 4.5 or 4.6GHz, but I'm confused as to what the voltage should be, as well as the frequencies of the cache etc.

What do I set my adaptive voltage to for these frequencies?

Do I leave the cache frequency and voltage on auto or change them to something else?

Thanks in advance for your help

Try 45 multi without any adjustment and take it from there, I can managed to get 4.6ghz at +0.05 v on the adaptive voltage.

Can leave the cache voltages are default, only adjust this if you are looking at raising the cache ratio

Tbh raising the cache shows very little gains, though at stock my board overvolts it quite a lot. 1.2700, ive backed it down to 1.200 without issue.

I run 1.236 for 4.5.

Just wondering to get one of these and thinking how much better it would be over my i5 4670k. I keep reading that if you are going 980 SLI you need an i7.

I am just about to swap out an i5 4670k for an i7 4790K so I am happy to do a couple of before and afters. Any particular tests that you want to see?

Using stock settings the I5 rated 534 in Cinebench R15 with an Open GL rating of 134.13

3dMark 11 Basic Edition Benchmark gave the I5 a score of P17690 (my GPUs are twin Radeon R9 290s). Graphics score 28905, Physics 8142, Combined 8225

Thanks but check my sig already done it. Massive boost my 3dMark 11 score is now 22000+ up from P16000

Currently not OC'd it or my 980's yet dont feel the need. My MB on Intel Boost gives it 1.23v so I reckon I might have got a good OC'er too.

Windows Experience Score with the I5 was 7.7 overall with the processor being the most limitng. This stayed at 7.7 after the upgrade. WTF? Maybe I had the I5 overclocked when I ran the previous score

Chuffbaby · 24 Mar 2015 at 10:43

No problem. These results may be helpful to others considering the upgrade

Chuffbaby · 24 Mar 2015 at 10:46

Cinebench R15 Cpu score went up to 835 cb and the Open GL went up to 149.66

Chuffbaby · 24 Mar 2015 at 10:51

Overall 3d Mark 11 score is now 19672. Graphics 29107, Physics 10833, Combined 8913

All tests done at stock. I plan to do some mild overclocking later but have to rebuild my son's PC first!

I run 1.30v for 4.7ghz, it will game at 4.8 but give it any kind of synthetic test and it falls over. however @ 4.7 its happy to run anything 24/7. However i am running mine on a custom water loop 1.30v on air might get toasty.
