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

they are all decent,i don't think ive seen a poor one,but generally speaking the L4's seem to clock slightly higher with slightly lower volts

yes theres the odd few L3 chips that run better also but not as many as there are L4's

idk why,maybe just a better silicon or better paste application
 
Ive hit 953 @4.7ghz, ram at 2400mhz, 10-11-11-31, 2T on cb R15. So it definitely seems low.

On another note, messing around with Aida64 stress test, ran it just now at stock and included FPU test, temps only maxing at 67c. Much lower than p95 ver 28.5.

Don't know why my HeroVI wants to put 1.248v thru mines on auto at full load. Seems far too high @stock. I got it passing realbench with adaptive voltage and a negative offset of 0.110 to give it a vcore of 1.132'ish which means temps only go to 55-60ish. Will see if I can knock off some more if possible.

Also got it passing @4.7 with adaptive +0.025. Defo feel I can hit 4.9 stable and maybe... MAYBE at a push get to 5ghz. Although will probably run with a 24/7 of 4.7

Also seeing 1.248v at load under Aida64 at stock speed, speedstep etc enabled.Voltage in cpuz fluctuating from 0.160 to 0.304, (not to mention loads between).

Cpu-Z does that fluctuation on mines if I disable Asus multicore enhancement. On auto cpu-z shows it at 0.720v idle upto 1.248v fully loaded.

I am not actually understanding exactly what multicore enhancement does though tbh.

I am still really just experimenting with it and not had a great deal of spare time to really get stuck in to it as yet.

Hi, just joined the 4790k club, with a new Gigabyte GA-Z97X-UD5H.
I have upgraded from an i7 - 950 which I had clocked at 4.2ghz. Reused 3 sticks of 4GB G Skill DDR3 memory (800Mhz) and managed to pick up an extra stick to give me 16GB Ram.
Now, my 4790k at stock, drops voltage down to 0.7257v when running at 800Mhz, but up to 1.2714v when running at 4400Mhz, so a little higher than yours Five.Stars.
My CPU is L418C134 and I Have upped BIOS to F7 as Auto voltages were crazy with earlier BIOS versions!

So, I have tried to alter only the CPU core voltage and got it down to 1.2v,but Cinebench 1.15 refused to even load, despite Wprime 210 and Cinebench R15, running correctly.

Also tried a basic overclock 4.7 at 1.31v, just amending the CPU multiplier and CPU Core voltage. Left all else on Auto.
Am I missing something else and keeping this too simple???

Stock At 4.7
Cinebench 1.15 9.45 9.99
Cinebench R15 870 925
WPrime 210 32m 7.454 7.056
WPrime 1024m 189.072 177.443

Sorry no screen grabs!!
Temps maxed around 71C at 4.7 On Swiftech H220.
My temps Min Max at stock
Core 0 27 60
Core 1 24 61
Core 2 25 64
Core 3 24 57

Sorry for all the info, just looking for clarification that things are right :confused:

Just a quick note for those wondering if they should upgrade....
My i7 950 at 4.2 scores....WPrime 32m - 11.421
1024m - 329.812
Cinebench 1.15 - 6.15
Cinebench R15 - 562

So roughly speaking it is between 55% and 75% faster at similar clock speeds! (Before overclocking)

Everything looks good there although going strictly from memory. Not at desktop at the moment and wont get chance to look at my benchy results until tomorrow afternoon, but at first glance everything seems spot-on.

Defo feel the voltages the boards are putting through the cpu at stock are slightly excessive. Your idle temps are 4 or 5 degrees better than mines for what it is worth and I am on custom water. Will need to remove block and repaste now that I have got a fresh supply of Gelid Xtreme though since I am using some inferior stuff at the moment.

Thanks for quick response Five.Stars, it is always good to have a second opinion.....now just to learn the tricks to overclocking. I soon realised the auto overclock pushed voltages into the high 1.4's even 1.5s. Ouch!

1.4+ keep well away / 1.5v is CPU death territory :eek: unless your 8pack using LN2

My gaming 3 was pushing 1.4v on idle on auto with the L3 bios. I got scared when I saw the temps at 33 deg on a h105 and thought I had a dud chip until I saw the voltage.

Manually changed it to 1,175v and did the update to latest, and now auto is dropping it below 1v on low load. Still need to check full load but temps are 24 deg max on idle on a single core.
 
Gave the 4.6 profile in my mobo's bios a quick try, vcore at load in games of 1.312, max temp of 61c. Might see if i can go a bit higher using theese settings as a base. Try to get voltage down a bit. Gaming and a few benches will be the most stressful things ill be running.
 
4.8@ 1.29v runs cinebench r15, just a quick test then went back to my 24/7.
4.7 @ 1.23v stable for 24/7 use.
L336D106

Going by the results on OCN from the l336d105/106 batch I don't think I'd switch this chip for an L4, the L3 117-120 batch however I wouldn't even open the box.
