Thanks using the voltages you listed Ive been able to get 4.8ghz core and 4.8ghz uncore but with only 1.257vcore :)

One question though, do you know what voltage is being set when the vring is set to auto? Reason I ask is because when I set the vring to 1.2v I can't get the system stable but I can when set to auto

yeah that one is a weird one indeed lol not sure though if you run aida32 sensor tab it will show you a setting called : VCCIO : @1.057v i think that is the vring voltage.
cause if i bump vring up and do a on the fly comparison with the VCCIO voltgae displayed in the left part of the screen where your vcore is and stuff it goes up with vring.

though yeah i experianced the same thing 1.200v would not post or crash but auto wouldnt lol

Ok, hold on then and I will show you every page of the BIOS I have adjusted to get 4.7GHz, copy it and see what happens.


EDIT< TRY THIS AND REPORT BACK<

Remember to reset everything to default before hand just incase you adjusted something else.

hi Stulid

did it, but it wouldn't accept 4.7, it defaulted back down to 4.6, it did this three times, i used roughly the settings you gave me

vcore = 1.334
vccin = 2.20

i'm quite happy with this, interestingly when you adjust the BIOS it messes up the GPU settings, i thought it was doing this, the GPU core was too high at 1.2v, it has to be 1.12v...

the 7990 is running very hot in Heaven, it's about 97 degrees, it rose to 99 degrees with the front panel back on, so that's staying off from now on

i'm not happy with the 7990 !!!! there's a pool of very hot air around the first fan, closest fan to the rear panel.

thanks a lot for your help

Can you F12 every page of your BIOS and show me what you have set.

Adjusting the CPU should have also no effect on your GPU which should be controlled by itself and the power gets from the PSU+slot.
 
Had my 4790K setup for a couple of weeks now and haven't tried oc'ing anything yet... I'm sure my Asrock Z97 Extreme4 can handle it though (excellent value board so far :)). What kind of voltages are you guys getting running stock? My core voltage hits 1.263V when it auto boosts to 4.4GHz. Is that a normal amout of juice for this chip?
 
I had to flash the BIOS on my AsRock Z97 Pro4 for it to recognise my chip specifically as a 4790K and access the full K CPU OC controls. But the 4.7GHz auto setting ramped VCore to 1.4V too.

I eventually dialled back to 1.223V for 4.7GHz AIDA64 stable. I was hovering around 4.8 and 4.9 with various levels of stability so I'd love to know what that chip could do on a proper OC board, but it's a client build since delivered :(
 
Try real bench over aida to see if it's stable.

Have only found aida good for memory stability testing. Often can easily pass that on cpu oc and fail in cinebench or real bench.
 
Hello all,

I'm after a bit of overclocking advice. I purchased a 4790k with a z97x g7 mobo around 3-4 weeks ago. I've resisted overclocking up until now but I guess that isn't really the point with this CPU/mobo.

I've not overclocked anything since my E5200 so I'm really out of touch. I saw stulids BIOS settings on the previous pages, is it a case of putting these in and crossing fingers or should I start with lower clocks / voltages?

I've got a raijintek themis direct contact cooler. Idle temps in hwmonitor are 28-32. In game temps are around 60.

On a slightly related note, I'm not sure how accurate hwmonitor is? I was using core temp fine until last night and then as soon as I opened it my whole system would crash. I googled it and found lots of other people on windows 8.1 having the same issue, just strange it had previously been fine for me!

Thanks
 
Hmm, just recently installed a 4790k and the thing is crazy hot. Under Prime95 I'm getting around 96c :/

It's on a H100i cooler as well. Guess I'll try a different set of thermal paste or something.
 
Don't worry about prime too much. Check temps in games/stuff you use every day.

The thermal paste that comes with a h100i is premium stuff. So unless you installed the block or backplate wrong then that isn't the issue. As for the backplate just double check it is orientated correctly and not able to move at all. Make sure you have updated your bios, early bios revisions were over volting DC chips quite a bit at the start.

What's your voltage of your chip at load (games)?

Only delidding will drop temps, which is what I'll be doing this week.

Just delidded mine, very easy (with vice) and quicker/safer than the knife method.

Around 10c at load (Handbrake), idle is a little lower and temps more even across the cores. Hmm bsod 101 as i attempt 4.8.

Cpu core 1.330
Cpu cache 1.200
Cpu sys agent +0.200
Cpu i/o + 0.200
Cpu analog +0.200
Svid disabled
Inititial cpu input voltage 1.900
Eventual cpu input voltage auto
Core 1, 2, 3 and 4 at 48 multi.
Min cpu cache 43
Max cpu cache 43
Ram at XMP.
Vccin shadow voltage 2.00
Load line calibration level 8
Cpu power phase extreme

No chance of 4.8 on my chip unless I go higher than 1.35v (which I'm not going to do). Boots and runs Cinebench at 4.8 1.32v but BSODs with Handbrake. I am settling with 4.7 @ 1.29 temps around 70c load. Will tighten my Ram timings and increase the Cache, happy chappy for now.

Thinking of deliding mine tbh. The temps seem bad to me on water. Have a 10degC difference between core 3 and 4 :eek:

Might try the vice method myself. Sticking stanley blades into a cpu just seems wrong!
Although putting said CPU into vice ain't any better :rolleyes:

Was my concern also, but pad out the vice with tissue so the grips don't leave any indentations. You could heat the IHS with a hairdryer to potentially loosen/soften the black glue that bonds the IHS to the silicone ( I did this for 60 seconds ). Magic tape the opposite edge of the CPU so it doesn't go flying when released, perhaps have a towel or pillow underneath to catch it (as a failsafe). Three taps with a hammer ( I used 2x2 hardwood ) and on the third I could see movement so peeled off with my fingers. No damage whatsoever to my CPU.

Also, I tried the razor method previously on a 4770K and the above was far quicker and safer (for me, with the 4790K).

Well! I've done it :cool:

What a difference !!! :eek:

19-20 deg at load and 8 at idle :D

Have pics of the original TIM. was like plastic more than TIM. the clue looks like automotive window glue to me :rolleyes:

Have to see later what the temps are like on BF4.

I can may be try for a decent overclock now ;)
