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

I guess I'll stick with whatever I can squeeze out of 1.3 volts. Last thing I need is a dead CPU this close to Christmas for a few hundred Megahertz. :p 4.6/4.8 is already pretty blistering as it is. I seem to have got a fairly decent chip which is nice.

Hopefully the next refresh scales to 5GHz without much trouble. Even a 10% increase should get us there!

Cheers.
 
Fine to up voltage for a few bench runs, cause tbh as you say keeping the voltage low in the 4.6-4.8 range for everyday use in my case is more than adequate. Will help with temps too particularly if your not delidded as mine is. I'm sure I could eek more out of thus chip but I don't really need to.
 
I'm delidded with liquid pro and a H80i jammed in my small case!. I couldn't even get away at stock speeds before hitting 100c in any stress test (with turbo disabled). Needs forced me to do it rather than any enthusiast leanings.:p

Still, it was a good learning experience.:)
 
People running this at 4.5ghz, what's the incentive to do that if unclocked (out of the box) it turbos upto 4.4ghz anyway?

They only turbo to 4.4 on one core at stock.

OK. Can't say mine is even get warm yet with any games I'm playing so I'll not worry about overclocking it (yet). Happy to let it ramp its own speed up and down...

Last night playing Elite Dangerous it was running at <40 degrees it was so under worked :)
 
Unfortunately I'm temporarily on the stock cooler that comes with the 4790K, as the Raijintek Pallas won't fit my Impact VII: the power board really is quite high and the cooler rather wide ;).

What kind of temperatures should I expect? Currently it hits thermal throttling which I don't think is normal even on the stock cooler so wondering is reseating it is worth a try?

(I'll get a better cooler, but have to measure things as there is not a lot of space in the 250D, but well more than formal specs say)

Stock cooler is bad on this cpu (expect 80c-100c)
you should look into Noctua C12P SE14
 
Thanks for that.

Definitely seeing the 100c. Case temp using a fridge thermometer on the cooler only gives me 30, 35 with the Strix doing some legwork. May not be as low as in big cases, but nothing that I think is a massive concern.

I'm seeing up to around 45 watts package power in hwinfo64, but what I think is peculiar is very rapid drops in temperature (3 seconds or so, sampling interval of hwinfo) from 100 to sub 70 when back to idle.

Is that the poor tim construction under the heat spreader, or poor transfer from package to cooler?
 
Just like to add: the strix doesn't struggle at all to shed its heat, it manages to run significant parts of 3d Mark with the fans off, and the cpu only goes 80c, so shouldn't restrict the gpu performance due to throttling etc. The strix pretty much scores as expected as well without OC.

Unfortunately I think this cooler won't fit either: I think it will reach beyond the memory, and I only have 95mm clearance (Says spec) under my bluray, which reaches pretty much that far back once sata/power are connected...

So my options are tower coolers below around 155mm, Corsair H100i with 25mm fans, or Raijintek triton with 13mm fans. I'd prefer air, as it is a bit less involved, but the case design is definately in favour of a 240mm rad.

So guys, I just finished my testing.

The results are quite impressive :)
4.8G_1.22v
4.9G_1.29v
5.0G_1.415v

Real Bench:benchmark 10x pass + 8h stability test pass.

All on water.
Cpu delided, no IHS used, Coollaboratory Liquid PRO used.

5.0G_1.415v = ~60C in asus real bench H264 bench test.


Happy Christmas :D

Very nice results :) What uncore speed are you running?
Also what are your other voltages set at? Vrin, ring voltage and system agent and i/o analogue and digital volts
 
Just started running the 4790k on the maximus impact vii and I'm rather baffled as to how to set it up. Using a Silverstone AR06 low profile cooler so don't expect ice cool temps. I seem to be idling between 30 and 40C. I think I have a touch too much paste on there but it was so awkward to get it I'm not going to reset it unless I absolutely need to.

In XMP mode #2 [email protected] it seems to run at rather high voltages >1.2 and doesn't drop much.
If I leave it as it is when the bios is fresh flashed it seems ok and BIOS reports voltage as 1.056 (from memory), but the RAM runs at 1.65V (knew I should have gone for the low profile crucial stuff), when I change the RAM to 1.5V @1600mhz it seems to change some of the auto settings because it considers it as overclocking. I am not 100% sure of this, though.
Tried running a bit of prime95 and it seems to go ok, fft massively ramps up temperature. Over 80 according to AI suite and core temp reports close to 100 on individual cores. Stable at a glance, though it seems to do a bit of thermal throttling, but I'm not sure. Asus AI reports @4400mhz but sometimes 4200mhz. I don't care too much if it throttles unrealistic loads.

I tried turning off multicore enhancement but it went a bit weird, core voltages were reporting as 0V by AI suite and idle temps were over 40 as opposed to mid 30s (
The asus software is a bit confusing, I'm not sure if it's over-riding the bios settings or what.

Somewhat overwhelming coming from 775, I'm not entirely sure where to start on this, I don't want to overclock the system as the low profile cooler won't take it. It seems ok as it is but really not sure.

The AR06 seemed to be the best air cooler I could fit on within my height restrictions. Only just fits, though, one copper pipe was a mm longer than the others and made it awkward to get it because it was so close to the daughter board. Once it's in there is a gap but there's not much in the way of wriggle room so it was very awkward lining it up.
 
Try setting the XMP profiles manually ,XMP will change more than just the memory settings.When i was using the standard cooler temps skyrocketed
when i enabled XMP profile(no problem with my custom loop).

Just to be sure of what you mean.
I.e note down the values for the xmp profile and enter the timings and voltage in to the bios in manual mode?

In that case you may want to check this:
NH-U9S
NH-9DL

Small 90 coolers _ check their specs!
