The voltage, tried as far as 1.42. Same results..
Is that a dump of the information that is needed to make an evaluation? I understand you need a lot of patient to deal with someone who is learning, like me..
That screenshot is helpful, but not yet enough. That shows what the XMP profile is for both 3600 and 4000. Are you choosing those specific profiles in the BIOS? Is it stable at 3600? But won't boot at 4000 - is that what you're saying?
I want to see the actual memory timings you are running with at 3600. Go to this page
and download and install the Timing Configurator ver:4.0.4. Then, run it at whatever speed it is stable at and capture a screenshot and post here.
It would be best if we can see the timings for a speed that is stable and then you can tell us what you tried at 4000 that wouldn't even boot. If you just selected the XMP profile for 4000, tell us that. If you changed any of the main timings and set the speed at 4000, tell us that. We need to know exactly what you're doing and what works and doesn't work. When you just tell us "doesn't work at 4000", that isn't enough for us to know what does and doesn't work to know what to suggest next.
Without knowing what you've already done, this would be my suggestion.
First, run at 3600 by selecting that XMP profile in the BIOS and leaving all other memory-related settings on "auto". Test stability with RAMTest to 4000% or four full passes of PassMark's MemTest86 (all tests, sequential CPUs, not running in parallel mode or run 30 mins of stress with Google StressAppTest or you can use HCI MemTest (I don't know the settings for that to be confident in stability). We need to know it's stable at 3600 before we make any assumptions about those timings when trying 4000.
Then, with nothing else running in the background (check in task manager to make sure nothing else is using more than 0.5% of the CPU) run AIDA64 Extreme, goto Tools/Cache and Memory Benchmark and select Start Benchmark. After that finishes, grab a screenshot and save it. You will want to compare this to whatever you get when you get it stable at 4000 to see which is actually faster.
Then, run the ASRock Timing Configurator and grab a screenshot of all the timings at 3600MHz.
Then, select the XMP profile for 4000MHz. Make sure VCCIO 1.25V, VCCSA 1.25V, DRAM voltage 1.42V. Attempt to boot and report back what happens.
If it won't boot, you can raise the DRAM voltage to 1.45V and try again. Report what happens.
If it still won't boot, then trying changing the primary timings from 19-21-21-42 to 20-22-22-43 and try again.
If you get it to boot anywhere in here, do one of the above memory tests to see if you're stable. If you are stable, then run the AIDA64 memory benchmark again and report all the results back here.
If these minor tweaks won't get you stable at 4000, then you may want to return your memory as it won't give you what it was advertised to give you.
FYI, if I go to Kingston's site, I don't see your memory listed as certified for your particular motherboard. This seems to be the list
. I do see that memory listed on the QVL for your motherboard
and ASUS lists it for the 4000MHz speed and timings.
