It's not advised to combine CSM-BIOS and SSDs, it significantly limits their performance. You'd need to boot a live CD in legacy and EFI modes, and compare dmesg to see the consequences of either choice on your particular hardware. But so far I've yet to see a CSM not put AHCI in IDE mode, rather than fully native AHCI mode. And that limits performance. Further, ACPI is typically limited as well, that will inhibit battery life on a laptop.

Honestly, there's no guarantee this is true if you're using memtest86+ 4.20 in CSM-BIOS mode. It should work, but there can be bugs that cause false positives. I'd try it with memtest86+ 5.00 beta6, and also check their forums to see about others using legacy mode for doing memory tests on EFI hardware. The manufacturers should supply, or fund OSS, to produce a native UEFI application memory tester. They're the ones going down the UEFI road, they need to provide the proper tools.
