Thanks to folks at G.Skill got a new DDR2 kit of memory to play with - 2x1GB G.Skill F2-8500CL5D-2GBPK 8 layer PCB dual channel kit. All that I have been told is that these use non-Micron D9 ICs but not sure what they use but they seem to perform very well so far.

CAS4 Results​

Looks like 490mhz 4-4-4-12 is the limit at 2.19v bios set vdimm. Setting CAS5 as in 5-4-4-12/15 didn't help but it could do 5-5-4-x easily at higher clocks. 2.23-2.27v vdimm allowed less memtest86+ v2.00 errors but still were a few when looping test #5.

wow,im very interested in the ics these are running.non micron doing 600 is very impressive.
well done eva!
 
Nicely done...you're going to generate alot of interest in these modules with those results. :)
 
Eva, do you plan to remove the heatspreaders for a picture for all of us to find out what ICs they are?

so far they seem like promos
