MemTest86 test versus Ryzen 2700X base and boost clocks.

I have been testing Corsair Vengeance Pro RGB Ram on a Ryzen 2700X build.
I need to verify that the installed memory passes MemTest86 with any given BIOS settings and memory clock timings before booting into a Windows 10 OS drive.
I have already discovered the danger of just setting predefined XMP profile and booting into Windows OS without running MemTest86 and ensuring it passes with Ryzen 2700x and X470 motherboard.
It results in a totally corrupted OS and required reinstall of Windows 10.


The Ryzen 2700X specification states this:


AMD Ryzen™ 7 2700X

Base Clock
Max Boost Clock

2nd Gen Ryzen™ 7 2700X Desktop Processor | AMD 


This leads to the following question.


Which frequency multiplier should I set to test Memtest86 assuming single BCLK of 100MHz?


Should I run MemTest86 at 3.7 GHz i.e multiplier in BIOS = 37 to ensure that MemTest86 passes at Base Clock

3.7GHz ?

Should I run MemTest86 at 4.3 GHz i.e multiplier in BIOS = 43 to ensure that MemTest86 passes at Max Boost Clock 4.3GHz ?

Should MemTest86 be able to pass at both conditions?

Has anyone on this forum tested these conditions?
