Is the overclock being done in the BIOS? That should be independent of Windows.Is there any way to run Memtest86 in Windows? I want to stress test a memory OC, but the bootable Memtest86 reverts to stock memory speed for its test.
It is possible the motherboard won't support it. I am not an overclocker, especially not beyond manufacturer's recommendations. I am not terribly qualified to assist much more.Sorry for the late reply. No internet for a while. Yes, the OC is done in BIOS. I set DDR4 3000 MHz RAM to 3200MHz ( I know, not much difference), but memtest reports 3000MHz when it runs.
What other settings did you change? Did you increase voltage or change timings?Sorry for the late reply. No internet for a while. Yes, the OC is done in BIOS. I set DDR4 3000 MHz RAM to 3200MHz ( I know, not much difference), but memtest reports 3000MHz when it runs.
Nope, just clicked on 3200 in the BIOS options. The system is stable in Win10 at 3200, that's not the problem. It's memtest that won't use the 3200MHz setting when it runs. Defaults to the RAM's SPD of 3000MHZ .What other settings did you change? Did you increase voltage or change timings?
Memory testing programs don't change the speed of the ram, because that is controlled by the motherboard. If the speed is 3000 in the memory test, it means the overclock failed and went back to previously working settings. You need to actually set the speed, timing and voltage or 3200 won't work. When you set 3200, try settings cas latency to 14 or 16 and voltage to 1.35v.Nope, just clicked on 3200 in the BIOS options. The system is stable in Win10 at 3200, that's not the problem.

I just said that the 200MHz RAM OC is stable. I have run stress test and tens of hours of games in W10 with the RAM at 3200MHz. It's just memtest that "resets" the speed back to 3000MHz somehow before it runs. Or at least that is what it is reporting.Memory testing programs don't change the speed of the ram, because that is controlled by the motherboard.

Post your system specs including the CPU, motherboard, memory brand and model number. There is a chance that your parts are to blame for why 3200 doesn't work.
How do you actually know it's running at 3200 when the memory tester is reporting 3000? What have you used to check that it's actually 3200MT/s (1600Mhz)?I just said that the 200MHz RAM OC is stable.
That is what the UEFI/BIOS reports, and that is what CPU-Z reports... to think of a couple off the top of my head.How do you actually know it's running at 3200 when the memory tester is reporting 3000? What have you used to check that it's actually 3200MT/s (1600Mhz)?
I was thinking that would be a more stressful test than just my daily usage up to this point. Not really necessary, I suppose.If it's completely stable in Windows why are you worrying yourself about running Memtest?
I just wanted to confirm, because memtest86 only reports the SPD information from the modules and not the currently set speed of the modules. I didn't mean for it to seem rude incase it did.That is what the UEFI/BIOS reports, and that is what CPU-Z reports... to think of a couple off the top of my head.
