I was testing my memory using recently, using memtest86+ turns out one of my stick was bad. But I noticed that one of my channels not the other, registered a 6-6-6-20 latency when my ram is designed for 9-9-9-24 and is set to and shows that in the bios. I ran a 3dmark recently and it stated my memory speed as 600 something mhz rather than the 800 (1600 ddr3) it is designed and set for.
The latency was listed correctly when testing in the other channel and this occurred with both stick of memory.
Has anyone encountered this before and does it suggest something malfunctioning on my motherboard?
I should say the computer had some more serious issues recently which turned out to be a failed cpu, and during that time the bios was updated and flashed. this is within the last few weeks.
Mobo: Gigabyte Z68XP-UD4
Memory: 8gb (2x4gb) Corsair Vengeance, currently running just the one, while waiting for rma on the other stick
Video Card: Nvidia gtx 560 ti
psu: Seasonic 850w Gold certified
There's generally on of (2) two methods on Intel XMP or manually setting the RAM. Your RAM that you RMA'ed could have been fine IF the MOBO misread the encoded 'SPD' information of the stick which is another good reason not to use Defaults. /edit - NO LGA 1155 Defaults to anything >DDR3-1333.
