T440p XMP profile selector not working properly #19

Closed renoxtv closed 2 years ago

renoxtv commented 2 years ago

After applying xx40_xx50_patches_v7.txt with the "show XMP and manual memory timings (cleaned up)" enabled, I now have options to select a memory profile. With a normal non XMP stick, I get Default Profile, XMP 1 and XMP 2, with XMP 1 profile having manual timing control, but CAS latency can go only to 10 and not any higher which is not acceptable. After I flashed a XMP profile to my RAM's SPD, I now only have XMP Profile 1 as an option with the manual timings, which in this case, CL10 is too low and the laptop won't boot with it. Tried flashing 2 different XMP profiles, even to a ram stick that was not the OEM hynix one, no dice. Attached some pics photo_2022-05-07_20-11-12 photo_2022-05-07_20-11-39

Not sure how you flashed XMP in a T440p, haswell MRC has SPD+XMP write disabled. Regardless, nothing I can do about this.
