Well at 4.8 it's around 15% faster than stock, but couldn't test anything really on as i didn't want to put 1.45v to get it stable

15% improvement in clock speeds does not translate to 15% improvement in fps though. :'(

Again, I guess it is a sweetspot thing.

Does your pc live in a freezer? Coz that is damn impressive temps at 4.8ghz. Mine on the CM 212 air used to max out at 65, which was okay for me but obviously i'd prefer cooler. And agree 100%, the 'jump' between 4.5 and 5 is actually not that impressive for games. I actually experienced worse performance going anything over 4.7 - probably related to stability issues. Finding the sweet spot for everything working together gives a sense of accomplishment though
I'm running under a CM ML240L in a nzxt H500 case, I have to say I'm really impressed with the case airflow which, if you look at the design you'd never think it would do so great in the airflow department.

I am relieved, and somewhat disappointed that my CPU overclock is going to be a 2 click thing.

Don't think of the "increase multiplier" as all you could do. Lowering your volts and finding the lowest it can go whilst still keeping said multiplayer is part of OCing and where some more tinkering comes into play

Yeah I realise there is a bunch more tinkering of fiddling that I can do, and I intend to do that. :D

What's your RAM speed, that is your bottleneck if under 2133Mhz. I got 2400Mhz Dom PLats juuust to be sure. I can prob push the DP's to 2600-2800 but havn't tried yet.

Use Auto Oc til failure, then bring the Mhz down by 100Mhz until it is game stable. I stopped using Prime 95 etc etc ages ago. All I want is game / daily stability. I recon a mix of well optimised & poorly optimised CPU / GPU heavy games (respectively) would be a decent test. Also keep a excel log of each parts OC / volts /fps and if you want, temps.

Not sure if I missed a comment but what temps are you getting on your GPU and CPU with the overclocks?

Thought I would revive this old thread, since I will be making some major adjustments to my fan config this weekend. (As per the GPU cooling thread).

I did a simple bump on my core speeds to 43 multiplier and enabled my xmp profile.

Temps are hovering around 55 - 60degrees under load, with the H80i in a push/pull exhaust config with stock fans.

Not too sure if this is good or not. I could always change the tim when I replace the fans with something quieter.

Having a lot of time in the evenings when out of the country, I tend to read up on PC stuffs, this time round it is the potential platform upgrade I am looking at... Then it hit me:

I am not getting as much from the 4790k as I should be. I am running at 55-60 degrees on a 43 multiplier. Which seems to run too hot, considering that I made the mistake of potentially UNDER volting it!?

According to Intel @ Intel® Core™ i7-4790K Processor (8M Cache, up to 4.40 GHz) Product Specifications , my 4790k should do 4.40 stock out of the box... Which means that I should be able to push 4.7+ with the h80i...

Something is up...

Delid, Delid, Delid! (imagine me jumping around outside your house with this written on a board shouting it ) and unfortunately there is only so much heat a 120mm rad can get rid of, I saw crazy good temp drops going from 120mm to 240mm

Delid is in the works for sure... Might get it done sooner than later.

60degrees at 4.3 seems excessive even for a thicc h80? I might be wrong. No idle temps really as it is always at 4.3 according to cpu-z. I am doing something wrong. :/

Hhmm, it really depends on a lot of factors though. I remember my 4790k at 4.5ghz being no higher than 65 degrees on a 212 (air) during games like PUBG. 60 degrees isnt bad, but what is your ambient temp there at the moment? (assuming you're in Bots) also, pictures of your case/setup?

intel 4.4 is single core clock speed, are you OCing all the cores to 4.3 or just one? if all core then you must ecpect it run much hotter than with the single core boost clock of 4.4. A delid will help a lot but your cooler will be holding you back.

PC is at home in Pretoria. I have NO idea on ambient temps dude, would be a fat guess. 22degrees? :p

2 intake at the front pull through the gpu radiator, cpu cooler push/pull as exhaust and no fans on the top. PSU is isolated, intake bottom and vents itself.

Planning on replacing all fans the weekend, along with an additional intake at the top. (just to the right of the cpu cooler)

Also remember in your current config you are pumping the hot air from the gpu through your case.

I understand that... But GPU is on 28degrees, and CPU almost instantly at ~60. Would that add an additional ~10degrees on what I would expect on my cpu?

Instantly on 60 is a big no no, so it hits 60 when you just start up the pc?
