Long time since I've been here, now I'm looking at a new config for which i need help

[optimist]

Currently I have an Core i7-920 Processor. I've had this since i came out and it have served me well.

Though i cant get past 3.8GHz without running a core voltage of 1.5v. I've been content just running at that speed.

Now this one is getting old, both CPU, Mobo, Ram and Psu so im looking for replacement parts. I like them to be overcloackable. I do have a custom build watercooling solution which have plenty headroom for a more aggressive computer.

I have been looking at the following CPU, Mobo and ram
GA-Z97X-SOC Force*
Core i7 I7-4790K 8 MB**
Crucial ballistics 2 x 8 GB : BLT2CP8G3D1608DT1TX0CEU***

* I have chosen a gigabyte mobo becuase that is what i have in my current setup and it have worked without problems.

** This is the best available cpu which as i understand it have unlocked the core multiplier so this is what i am aming for. My current system have lasted for 5 years and can still keep up ( More to that ive upgraded my graphics). So my target is to get something that can last maybe the same amount of time. This is the reason for choosine the top line CPU.

*** Regarding memory i am at a loss. I have no clue to what to choose here and is essentially my primary question. What memory should i chose if i plan to OC?

I would like to know if anyone have any other ideas for CPU/MOBO combination and/or can recomend a good PSU. I do not beleve i need more than 800watts (not modular)

Two last questions, What Uses (other than gaming, which I will assume is primary), and what budget.

3D AutoCad rendering. Heavy on CPU
Reiviera-pre simulation.
Quartus II Synthesis. Heavy on memory.

Umm budget.. there is room for choosing the core i7.

From what I've seen here, I'd suggest 2x8GB GSkill Tridents in 2400/10, stick with the 4790K, and on the mobo, I'd go the Z97 Hero from Asus, the Z87 was the best of the Z87s and the Z97 is much improved, I'm running both of them (in sig), may have missed it, but what GPU, that will play highly in a PSU pick

Just an update. looks like i followed your suggestion in the end although different mobo. And have gotten the following results and are quite happy.

see cpu-z stats after bootup Note i did not do any OC'ing my self this is just the mobo autoclocking.

Thanks for the update!

That looks like a pretty good OC but I see how they did it: Vcore= 1.373 v. Typically, you don't want to exceed 1.300 v. on a Haswell chip but it also depends on CPU Temp.

Have you checked your CPU Temp while doing 3D AutoCad Rendering or other high CPU load program?

Sweet build, are those the Tridents?

Hi
Know this is an old post but my system is finally done. Temperature is nothing i have an over amped watercooling system. temperatures never really exceeds 50c.
That being said I did clock it down to 4.6GHz since it boosted the voltage further when executing heavy application up to 1.4v. and I tried it at 1.3v, as you suggested, where it was not stable. Now i run it at 1.25v which is better.

Pick as the solution

If you can run 4.6 GHz @ 1.25 v. that's very good. I originally stated that 1.300 v. was the maximum for Haswell, but you have a "Devil's Canyon" CPU which can go to 1.35 v. max. I'm not sure, but I believe that is based upon Air Cooling. You should be able to go higher with only 50*C. temp. but I can't say exactly how much. 4.6 GHz is still pretty respectable.
