Hi,
The Intel website is a mess - even if they wanted to update it I don't think they could.
However, I can confirm that the Corsair XMSII PC6400 12-12-12-5 works just fine in teh DP965LT. I hav ebuild 5 machines so far with this mobo and RAM, runing either 2Gb or 4GB with zero problems.
Well - one duff RAM stick actually, but that was the RAM itself, quite clearly.
Thopugh there is no way to see it, the 1.9V thing was addes some time ago - bios 1233 maybe, and in fact I had the Corsair running stable on 1.8V before that Bios fix.
So you should be fine.
