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

Had a little teething prob with my new 4790K - planning to run it at stock but a combination of having the cores synced in the BIOS and my Samsung Magician software running a Performance power plan meant that all cores were running at 4.4G full time and the Vcore was 1.279/1.280 - on prime the temps were climbing to 80c - I've only had the PC built for a day - would this cause degradation of the CPU already? Having turned off core syncing and changing the power plan my cores boost to 4.2G and only require 1.152v

80C is still safe for a 4790k, although it's rather high it shouldn't harm the chip in any way. Out of interest, what batch code is your chip from? And was it made in Vietnam?
 
I have an X5 batch, not pushed things too far but very comfortable 4.5 on 1.2v and managed 7 rounds of maximum intel burn on 4.6 at same voltage before BSOD.

Going to try a little more this week and see where it goes but happy to keep it steady for a while.
 
Think I've found my happy medium for now. 4.5 with 1.9v gives me the best balance of any combo I've tried in terms of gflops and temps, while remaining 24/7 stable.

 
I'm looking to build a new system from scratch in the next week or so, is it worth picking up a 4790k at the minute? I'm not too fussed about the Skylake stuff if the jump in performance isn't going to be that amazing, especially when compared with an OC'ed 4790k. Plus, I'm pretty impatient and would have to wait another couple of months.

I mean, I'd imagine I'm still going to just buy the 4790k anyway so I'm not sure why I'm even asking, I'm just wondering if it's basically going to stand the test of time over the next few years for gaming purposes or if it's really not worth it in comparison to this Skylake stuff?
 
I haven't pushed mine but it's stable at 4.4-1.130 volts. Maybe I'll push it more in future.

Idle at 28-30 haven't seen it go over 54c even in this weather under gaming.

I'd get the 4970 if I was buying now.
 
Down to 1.18v last night, going to keep dropping .01 daily and see how far I can go on 4.5. Temp spikes trying to push for 4.8 on 1.27 were getting low 90s so prefer keeping the 4.5 at lowest v possible. Might be able to do more with water cooling but, guess that's a project for down the line somewhere.

Ok, just about do run a burn test on 1.16v (you guys inspired me!) and have noticed that the lower the voltage, the higher the Gflops but the lower the amount of available RAM for the test.

Regardless of whether or not these are the right things to look for, they're providing a base for comparison.

Can anyone explain why the amount of RAM available drops with reduced CPU voltage, even though the RAM voltage has remained unchanged?
