45nm / DDR3 era Spi discuz.

[before]

Its bios related, not supporting bios is fast @1m and slow @32m so newer bios give you better performance on 32m .

It is. @IxTk we are currently investigating this matter. So far, I can only say that there are changes among both MSR and MCHBAR registers. Not sure if we'll find exactly what's happening.

BTW We are looking for dumps done with other motherboards than the P5E3 WS Pro which is the one we actually use. Making comparison with several different boards can help saving so much time.

If you're using Gigabyte X38-DQ6 - Bios: F2; Asus Maximus Formula SE - Bios: 0401; Asus P5K-E - Bios: 0503; or any other one with which the phenomenon occurs... Could you please save CPU-Z registers dumps (.txt) and then send them to me? What we need are 2 dumps, (1) with pre-45nm bios and (2) with post-45nm bios; both done under the same conditions (I mean the same bios settings).

If you wanna help but still have some questions, please feel free the ask me in pm...
