[Success] GIGABYTE Z370 Gaming 7 + Intel Core i7-8700K + RX 580 + (2x) Dell P2715Q 4k @ 60Hz

@elfcake, it is anything but a clunker.
I think the setting in the BIOS to increase the speed of your RAM is as per the screens shots below.
Use either the '+ - page up/down' keys or just type a value. To reset to auto just enter 'a'. I think then it will work as the Gaming 5 is very similar to our 7 Mobo.

Was able to bump up to 2500 GHz without problem.

Hi @elfcake, good stuff, I see you are running at 5.1GHz also. Have you any Geekbench scores? Also, have you the Extreme Memory Profile 1 (XMP) selected in BIOS?
OC'ing RAM is not a thing I have done and I will admit I'm no expert and since I have 3600MHz RAM I don't need to OC.

Yes to XMP in BIOS. I have since set OC to 4.7. Too much overheating at 5.1 and frequent crash and restarts.

These are the score as of this evening.

Also managed to get the ram running at 2600MHz!

One might glean from those results that OC'ing does not really give much of a boost?

 

[janardan]

Agree, not much gain. In OpenCL and Single Core, the gain is about 2.6%, only in multicore the gain is 6.9%

Is is worth the extra heat and possible long term failures? Not for me. Each to their own.

This system is already much faster than my prior Hackintosh, happy with what I have

Agree!

Just to add my 2c worth, just be careful of the F10 BIOS upgrade. Gigabyte has mucked around with the CPU voltage (it has been increased) and maybe other things that I don't understand, and the end result is lots of heat even at the stock CPU frequency.

Here is a Geekbench I took yesterday on F10 BIOS with 5.0GHz OC (I'm running a 280mm Corsair AIO water cooling). I also ran Blender doing the Classroom test using the CPU and the temp maxed out to 100C and then started to throttle the CPU frequency, I shut it down!


This is today, back on the F7 BIOS and OC at 4.9GHZ.

This is today running the Blender benchmark and monitoring the CPU temp. It never went over 83C, which is good! This is with my Fans set up in quiet mode.


I totally agree OC gives a little gain but is it worth it to have crashes instability and possibly shorten the life of your CPU.
FWIW I have 3600MHz RAM and that has made my GBench results a little faster.

Maybe later this week I will be delidding my CPU and using liquid metal on it, plus I have a 15% larger copper IHS that I'll fit.
My aim is to keep it at the 4.9GHz OC, but to reduce the temp, so I can then run my Corsair ML fans slower for a even quieter build. Plus I might try reducing the CPU voltage for even cooler running.

Here's another dumb question or three: I have an 8700K and the (see build mobo) and I don't want to fry it. Is it better to set the OC to the i3 8300 (?) 4.1 GHz and set the "Easy" setting of "Normal" or is the lowest i7 8700 ~4.7GHz OC setting with the "Easy" setting of "Saving" going to give be the desired reduced but Xeon-like evenness of performance. Does the BIOS/controller "know" what CPU I have in there when the OC is set? Or am I overriding beneficial features of my 8700K when I select a different CPU model? I'm not a gamer, I'm running Pro Tools and VSL/VEP6. I want to overclock responsibly. Temps have been good, Pro Tools will immediately run up and peg the CPU meter no matter how many cycles or cores it has to use. It's P. Piggly McHogswine's Porkinarium over here...

Hi @jiffyslot.
I'll try and answer the Q's to the best of my knowledge/understanding of OC'ing etc.
Others more knowledgeable in these matters please feel free to chime in!

1. I would not set the CPU to anything other than your CPU ie i7-8700K. Where are you setting your system to an i3-83xx?
2. I've never had a Xeon CPU, and I'm a little unsure as to what you mean by "evenness of performance" are you meaning the CPU frequency spikes that you see on your CPU when it is using Intel's SpeedStepping technology i.e. it changes the CPU frequency up and down based upon 'load'?
3. Yes, the BIOS does know what CPU you have and sets up various hardware and software 'things' appropriately. All Intel CPU's have information (ID's) embedded in them so the motherboard can read them.
4. The more cores that you can give the audio/video tools etc, the better. You say that you have it running fine temperature wise, maybe you can do a back to back test on how much you really gain with overclocking ie run an encoding session. I think you will be surprised at the small difference in real-world audio/video user-case. Things like RAM speed and hard disk speed will play a large part in the speed and feel of these systems.
5. I don't game either (unless you call a few games of Pinball gaming!), but I do a lot of compiling and I've started to play with Blender and might be doing some Youtube videos so I like to have a fast system. I've OC'ed to 4.9GHz and it's very stable on the F7 BIOS. I do have 3600MHz RAM. Your personal build profile is not visible to me when I click on your name under your Avatar then click on Profile, it says "This member limits who may view their full profile."
   So I'm not sure as to what you have memory wise.
6. I'm guessing you have air-cooling for your CPU, if it does get hot in your "P. Piggly McHogswine's Porkinarium" (LOL) then maybe consider upgrading to an all in one water cooling like what I have and the Corsair ML (Magnetic Levitation) fans that replaced the standard fans that came with my Fractal Design case. Made a huge difference to noise. I'd do a decibel check for you, but my brother hasn't returned my DB meter... it's only been a year or two!
