No way to tell exactly which? Shame

Not bios flashed yet, gone back to the samsungs until I get some free time. I'll post back up as soon as I have some stability above 2400 out of them. Must say Ive had nothing but trouble with the M5F bios and micron sticks. When you find a compatible bios it works great, but until you do it just tantalises you with suicide level stability.
