Sorry to bother you, David, but I have searched the forum, read a lot and tried to work around for days, but now I am stuck.
I'm trying to boot Memtest86 current version from an USB, that I have prepped with either dd or Ventoy lately. The machine is a Fujitsu RX4770M3 with four I7-8880 and 512 GB mem to test.
What I found out
1. Machine is in EFI mode, it's actually the only mode supported. BIOS is the latest one available. The CMOS battery low voltage is not relevant for booting
2. The memory setup stays put with all four channels populated on all 8 mem boards
2. I can exclude the USB drives, as the work fine in some HPE DL380G9 and other boxes, albeit the "error:" message above also comes there too, but only for a blink. I used two different sticks, also
3. The old version 4.37 works and boots. It's measurement is an interesting question, however.
Note:
The main objective actually is not the test the mem, it is the benchmarking of the memory combinations instead. It is pretty weird that some tests reveal a demolishing performance of about 1,9 Gbyte/sec, while others measure speed higher than the L3 Cache (see picture), which give question marks to me, too.
Here are some pictures taken that show the boot sequence. Error log would come handy, but cannot be retrieved, due to boot failure.Many thanks for giving me a hint
