CST Eureka Test Vs V7.4

[Nano]

Hello David,

We observed that the 8GB - SD @ 2400 Modules failed in CST , Eureka - 2400 tester but they passed in Memtest V7.4 ( Test 0 - 13 ) on Asus Z270 - K motherboard.

CST Eureka - 2400 - Tester	Chip Identified by Eureka	Windows 10 Installation (Single / Dual)	Windows 10 - Passmark 8.1 (3 Hours)	Memtest ( V7.4) Test ( 0 - 13) Asus Z270 - K, CPU - I5 @ 7400	BIOS Version
March - A	U1, U5	ok	OK	PASS	809
Check board, MAT, Mat +, Mat ++	U11	ok	Ok	PASS	809
March - B	U9	ok	Ok	PASS	809
March M, Hammer	U11	ok	Ok	PASS	809
March m, Hammer	U9	ok	Ok	PASS	809

Could you please let me know which test should i consider the correct one ?

Thanks.

Maybe the timings, refresh rates and voltages used were different between the ASUS motherboard and the hardware tester. So maybe the modules are in fact stable when used with that ASUS motherboard.

Also were you using multithreaded mode in MemTest86? Some of the ASUS boards had UEFI BIOS bugs that forced single threaded testing. See,

(Multi-thread mode provides a better test than single threaded)

The Multi thread mode is not enabled.

Multi-thread mode provides a better test (finds more errors faster), so turn it on if your motherboard BIOS supports it.
