Its just generic stuff at 3-4-4-8, 2.5v. I've tried changing voltage/timings as well with no effect.
edit: Eurgh, after hours of testing.. it seems it only works at 2T on this board. Cheapo nasty indeed
I thought DDR started at 2.6v+?
Is it running 1T on the other board, or does it need to be 2T on both boards? Could just be because it's generic stuff. What happens if you slap the voltage up to like 2.8 - 2.9v. Any more stable?
The DFI board has many many additional settings for memory, it's a dream for people who love to tweak. Perhaps try altering some of the below settings to aid stability.
Row Cycle Time (tRC) - 7 = best performance / 15-17 = best stability
Row Refersh Cycle Time (tRFC) - Usually set 2-4 clocks higher than (tRC)
Write Recovery Time (tWR) - 3 = best stability
Write to Read Delay (tWTR) - 2 = best stability
Read to Write Delay (tRTW) - 2 = best stability
Write CAS Latency (tWCL) - 1
DRAM Drive Strength - 3 / 5 / 7 = for TCCD modules
DRAM Data Drive Strength - (With CPC Enabled, i.e. 1T) 1 / 3.
Max Async Latency - 7-8ns
Read Preamble Time - 5-6ns
Idle Cycle Limit - AUTO (for low grade RAM)
Dynamic Counter - Disable for stability
Bypass Max - 7x
32 Byte Granulation - Enable 4 Burst for more stability.
(All info above from a handy BIOS Optimisation Guide for DFI motherboards. Can't find the web link now though).
