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

Installed my shiny new 4790k in a Gigabyte UD3-BK today. Thought the temps were a bit high, but hey it's a new chip and I don't know what's normal, and it was volting to 1.47!! I didn't notice for a few hours...

An update of the BIOS sorted it, and I've now manually set the voltage to 1.2. Idling at 28c now...

It's a scary thought that people who aren't looking for these things could be just installing the mobo/CPU and risk shortening the life of the chip..

Currently running at 4.5 with the ram @ 2133. I suppose I had better get up to speed on how to clock this thing properly.

Yep, all boards seemed to be volting very high on the first release biis versions, was the same on my older Z87 board.

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
Click to expand...
cache/uncore is at 4600mhz_1.24v(bios)_1.26v(windows)
sys agent and i/o voltages are at +0.150
vrin(vccin)=2.1(load)_5GHz
 
Right so if I manually use 1.6v 2133 11 13 13 XMP2 timings the voltages look more normal, in fact lower than auto! possibly because it's using 1.6V instead of 1.65 for the memory?

XMP seems to be what causes strange things to happen so thank's for the tip!
If I use the Asus "TPU" that automatically turns on xmp profile 1 and things go weird so I will leave it alone.

Though interestingly the temps at low frequencies don't seem to be particularly affected, seems to be the combination of voltage and frequency that ramps up the temps.

Need to play around a bit more but so far so good, so thanks for the tip!

1.35v on air for 24/7 use. But do not stress test with p95/ibt etc. The temps will hit insanely high levels.

You weren't joking. Tested IBT first and temps rocketed to 85c, so killed that quick. Running Asus Real Bench now and it's holding steady at 65c. That's stock and pulling 1.175v. Will try an overclock later once this is done and I'm happy it's not going to go any further in temps.

for prime95 u need a custom water loop.. :)

At least on Intel. Wasn't so punishing on the AMD 8320E I benched the other week. But I fired it up on this i7 and was immediately "ABORT! ABORT!".

Currently set the voltage to 1.2v and the multi to 46 and have Real Bench running in the background. Seems to be stable so far. If it completes this I'll drop to BIOS and kick it up to 48 and see if that stays stable at 1.2v.
 
Bah. 4.8 ran too hot, so I killed that and returned it to stock. Now my system is randomly locking up. Cleared BIOS, individual sticks of RAM, nothing. System just randomly locks up. Not even a blue screen.

Edit: Welp. System is proper ****ed. It simply crashes or hangs.

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

Small 90 coolers _ check their specs!
Click to expand...

That NH-U9S looks perfect, as it doesn't go outside the 95mm zone and will easily fit heightwise. Noctua doesn't compromise on quality, and that is reflected in price, so getting close to AIO territory.

The 250D will fit about 50mm worth of radiator+fans:
I guess both AIO's below should outperform the Noctua, even when using slim fans on the Triton. Initial impressions seem to indicate the Triton is not massively sensitive to airflow, so would it work adequately with the 13mm fans?

YOUR BASKET
1 x Noctua NH-U9S PU Cooler - 92mm £47.99
Total : £47.99.



YOUR BASKET
1 x Raijintek Triton Core Edition AIO Water Cooling Solution £54.95
2 x Raijintek Aeolus Beta fan, red / white - 120mm £7.90 (£15.80)
Total : £70.75.



YOUR BASKET
1 x Corsair Hydro H100i High Performance Liquid CPU Cooler (CW-9060009-WW) £88.00
Total : £88.00.

 
cant wait to get my new build home and start clocking it, got the SOC Force board too. Will be trying some of your tips! :)
 
Here are some simple settings for a 4.5GHz overclock on the uncore and core, this also keeps the Speedstep function where it drops to 800MHZ and drops the vcore to the minimum.

Remember your CPU may need a different value added to the offset voltage.


BIOS settings,

CPU-Z results,

So thats Speedstep working as it should.

Load an application and see how the core speed and Vcore jump up.

4.5 uncore too.


And dont forget to mess around with some of these,

I wish the MSI bios was as easy to navigate as the Gigabyte one. Can't even find LLC in the MSI one...

What's the safe max temp to run these at?
