I have one request.
the ballistix memory module xmp profile 1867/10-10-10-30-45 command rate T2 is not supported. The recognised memory timings are 11-11-11-32 with command rate T1, instead, of xmp profile or SPD jedec profile 1866 10-10-10-32, as seen from CPU-Z (or HWinfo64) that the memory module supports.

Can you fix the bios memory command rates bug in T420 bios?? It does not work
I think the bios memory option should be as follows as seen from other bios settings:

OneN Mode Support
Enable/Disable OneN Mode Support
Disabled
Enabled


If disabled then the 1N command rate will change to 2N.

The way it is it does not work. It always stays to 1N even if 2N mode is selected.

We also want the bios to support the XMP 1.3 EXTREME memory setting. If there was an XMP profile setting (as opposed to SPD) in the bios then it would be selected automatically I guess. Running memory clock at 1600MHz instead of 1867MHz it does run at SPD memory settings: 9-9-9-28 T1 which gives me slightly better passmark memory mark. Another method would be to replace one of the spd memory profiles with the xmp memory profile by purchasing the thaiphoon burner but I may risk bricking the memory modules. As a test, that the 2N mode does not work, in the bios advance memory settings when using also the 1600Mhz memory clock and we select the 2N mode the command rate still remains to T1. So there is a bug with the Nmode. Please correct.

Command Rates
1N=T1
2N=T2
I am now using the 1600Mhz (800MHz double data) clock since performance wise it is better until a solution is found.

SOS
However the memory module according to HWINFO64 also supports JEDEC SPD: 1733.3 (10-10-10-30). Can you please add this frequency to the BIOS memory settings?????

Also HWINFO64 also states that under JEDEC SPD profile: 933.3 (10-10-10-32) is supported but probably it is T2 command rate compatible that is why it cannot be set automatically.

I guess that if the bug with the Nmode support is fixed (1N and 2N) and the 1733.3 MHz memory frequency is added most problems will be solved as JEDEC SPD profile 1867 (10-10-10-32) is very similar to XMP profile 1867(10-10-10-30-T2).

Thanks
I have 2x4gb dual channel memory.
