I've run that bench before and everything seems good, GPU and CPU score well above similar systems but RAM doesn't score properly because it doesn't recognize and can't compare it to others. My SSD scored OK but HDD seemed a little low from memory. I still think for thoroughness I'll probably just get 3000 or 3200 and the 7700k in the coming weeks.
I up/downclocked my RAM a while ago and saw 0% change in rF2 FPS. Some recent games like Fallout 4 are heavily RAM speed dependent though, so for general gaming it does make some sense to use fast RAM.
What speeds did you go to up and down? I've noticed when My Son plays FH3 at certain times it stutters even when there is only about 40% on both CPU and GPU but RAM is over 8GB so was thinking my system was swapping over to my crappy 8GB stick from my better 2x4GB sticks causing the stutter. I don't see that stutter in anything else although in VR I do get drops from 90 to 45 a bit and was thinking the same thing could be happening.
Could you post your memory details (which modules you are using) and if possible some CPU-Z screenshots of the memoy timings of the 3 modules ? Timing is quite important to know and set in the BIOS.
I hope this means something to you . In my Bios i set them to 15,15,35 and 2400 and it reads 15,15,35 2400 there .
@2ndLastJedi First pic top left side, Channel # Dual, DRAM Frequency 1199,8 MHz > Your RAM is 2x 1199,8 = 2399,6 MHz
I don`t think 7700k is much better then your 6600k if bout are running at 4,6 GHz. I did look specifications and there are not much difference regarding game performance. The only thing I can think of which may cause stutters 6600k vs 7700k could be that 6600k has 6 MB Cache and 7700k has 8 MB Cache (CPU Cache is an area of fast memory located on the processor. Intel® Smart Cache refers to the architecture that allows all cores to dynamically share access to the last level cache) but S397 is working to solve performance issues and it is possible that next update could solve stuttering issues. I think it can be wise and try to optimize BIOS and windows before you go and buy new CPU and RAM excessively when RAM prices are as high as they are today.
Sadly, OEM memory is very difficult to find data about (this is normally only sold to factories and not retail but there is an open market for it). Neither the Apacer or the GEIL part number brings up any specs online. If you still have the packaging of the GEIL it should tell more about the name/type module or on the module itself as I believe this is a retail product. The Apacer is OEM so data will be unavailable. But looking at CPU-Z Max Bandwidth, it seems the system is running on 1066/1067 Max bandwidth thus 2133 MHz. A system with mixed memory modules (i.e. 2133 and 2400) will always downclock to the slower of the modules (2133). The tRAS for 1066 looks like it should be 36 instead of 35 for all modules, the 15-15-15 and 1,2v voltage seems correct. Run a benchmark on tRAS 35 and then try tRAS 36 for comparison benchmark. This is one of the main reasons why memory should be picked with care along with the rest of the components in the computer. Sadly a shop (or online) will sell you whats in stock or best profit margin unless you as the buyer specify your requirements. The moment you start pushing the performance, this is when discrepancies make themselves known.
On another point, your Apacer modules should be installed in slot #2 and slot #4 for Priority 1 according to the manual (page 21) ftp://europe.asrock.com/Manual/QIG/Z170%20Extreme4_multiQIG.pdf Read here : http://forum.asrock.com/forum_posts.asp?TID=1404&title=installing-memory-sticks In Intel's technical documents about their processors (which also contains the memory controller), they state that when using two DIMMs in a dual channel, four DIMM slot total board, they should be put in the slots that are the farthest away from the processor, for each channel. That would be the A2 and B2 slots. The Geil can be in slot #1 but I have had booting problems there occasionally on some mainboards, then move to slot#3
Have you said Apacer modules and Geil modules by mistake ? as i have two Geil and one Apacer ! If so your recommendation as by reading the manual is to move the two matching Dimms to slot 2 and 4 and put the single in slot one , then if issues booting move the single to slot 3 . Am i understanding this correctly ? If so i shall try this first thing in the morning .
This is what i've seen but in the other pics it shows 1066 (2133) so i've never known what it's actually running at . But i did see the 1199 and double it in my head and thought great its doing the 2400 but then i see all the other digits and thing 853 for slot #4 JEDEC #3 and get concerned . lol
@2ndLastJedi JEDEC # 6. tRAS and tRC seem not to be like as @ceecee mention in # 29. It can be a problem, run benchmark as @ceecee describes in #29 to see if there is a bottleneck.
Ari is correct ! Sorry, looks like not enough coffee was working yet (it was early morning in Belgium). DRAM Frequency is set to 1199,8 MHz (2400 MHz) so leave it on 15-15-15-35. The single Apacer is a 2133 module and is not clear if it is supporting being clocked at 2400 on those timings. The GEIL pair runs at XMP2400 so probably supports XMP 2.0 which the Apacer does not. The moving of the GEIL pair to A2 (Slot#2) and B2 (Slot#4) is correct though as explained above in the Intel piece. This in order to correctly enable the dual channel. But run a Benchmark before and after. The Apacer can be tried in either A1 (Slot#1) or B1 (Slot#3), try A1 (Slot#1) first and if there are any booting problems then move to B1 (Slot#3). A good idea is to run another benchmark without the 8GB 2133 MHz Apacer as well to see if this slower module is not bottlenecking the system. If you have the GEIL model data it will be handy though.

What benchmark would you suggest? A Ram specific one or just ROTTR or Firestrike or just the UserBenchmark?
The Userbenchmark will give you a quick oversight for the RAM change. http://www.userbenchmark.com/Software After for a more stringent test, 3DMark will push your computer hardware and turn up any weakness but ROTTR or Firestrike are also good. https://www.futuremark.com/downloads/3dmark.zip Here is a list of free benchmark tools. https://www.howtogeek.com/111733/how-to-benchmark-your-windows-pc-5-free-benchmarking-tools/ On removing the GEIL, can you check for any model/type names?
This is before swapping the dimms around .

This is after swapping Dimms around . I tried the Apacer in slot #1 but the system didnt boot just revved the fan up and down over and over so put it in slot #3 with the Geils in #2and #4 .

Ok, at least the memory is correctly configured now, the latency is not optimal. And have you benchmarked without the Apacer ? Another question, in the earlier CPU-Z screenshots, the GEIL is listed under SPD Rank: Single. Is this still the case ? If it has not changed to Rank : Dual, then the Apacer is conflicting. (Dual is Dual channel and optimal). And, do you have the GEIL model data yet ? The reason I keep asking is because it would be a lot cheaper to buy a compatible GEIL pair of the same speed and running all memory on Dual Channel. This would make the computer stable and efficient for gaming and as Ari said, memory is high priced at the moment. (the price goes up and down like gold and bitcoin!) Also, I see the last BIOS update for the Asrock Z170 Extreme4 is v7.20, in between there have been updates for memory compatibility. BIOS v7.20 will contain all the updates to date. What BIOS version are you running ?
I already updated to 7.20 in readiness for the 7700k. I didn't try without the Apacer, will do tomorrow and the Geil is still saying single and the Apacer is dual even though CPU says it's running dual channel in that first CPU pic and still the same after the Dimm swaps. I've looked to get the same Ram but they don't make them anymore. I'll find the exact ones and post a link.
https://m.umart.com.au/goods.php?id=33236 Here it is, these are the exact ones from the same store. When I started trying to find another 8GB I was only able to find similar but not the same. Not sure what would work or not but only buying 2 more 4GB Dimms would be great.
