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.
 
Solution
your ram run at 3200 mgz so it is overclock to max keep it this way since max jedec is only 3000 mgz dont try to go over or system might not boot .
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 .
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.

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.

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.

Now, it is possible that memtest is just reading the original default SPD of the RAM and erroneously reporting 3000MHz, when it is actually at 3200MHz. That is what I kinda suspect. I just don't know how to prove it.
