Hi BA... nope the sticks are 4 512M AA4T UTT-CH based. Plain old TMII from back in March. They were the 4 best sticks out of 8 TMII sticks I sorted. Sticks 5/6 are sitting 230Mhz 1T in NF7-S and 7/8 are sitting 220Mhz 2T in another NF7-S.
My 4 sticks of Twinmos SP 3200 ...AA4T also havent fair as well, 2 of the sticks suffer HIGH voltage issues and coldboot issues in NF4.
I have 2 sticks of the new BH in there now, not doing so great. 250Mhz but if 1T is used memtest 1.55.1 test#8 fails regardless. Im sure its probably a setting somewhere, but Ive tried everything in the bios so far. They dont run beyond 210Mhz in NF2 systems.
The nice thing about the UTT-CH chips was the fallback for not "great" sticks, they'd at least do better in NF2 systems then even most GOOD BH5 sticks, so the 4 of 8 that didnt pass muster found good homes that were still a heck of an improvement.
