R710 Memory Mismatch for identical ram
I know this topic has been beaten down to death but I just decided to drop this here and see what others thoughts were.
Im getting the ol' Unsupported Dimm. gotta be the same for each cpu error that stops boot but allows an F1 and the host sees and uses all the memory.
I have an r710 with all banks full of exact ram. All 18 sticks are 4gig, DDR3 - pc3-10600. The A bank is full of Hynix sticks and the B bank is full of Crucial sticks. Some of the crucial sticks are visually different (6 have heatsinks, 3 do not) but all 18 sticks are the same size and speed.
Thoughts?

DJReese,
Likely it is due to one of the dimms specifically, or the slot it is in. Could you confirm the model and part number for me, so I may verify if the dimms are compatible in the server, and slots it is in?
Thank you.

Chris,
Thanks for replying! Wanted to let you know that I will check on them when I get home this evening. Ill report back then.
As I was restarted the second host, it came up with the same error. Ill gather the memory details for the two hosts and post them here.
thanks again!

Thanks again for looking these up. If i need to mix them around for better placement, I can do that also.

The issue is likely due to variances in the dimms. The rule i think that it is having an issue with is that the channels must match each other across the dimms. as shown below. So Channel 0, 1, and 2 must match between the processors. You actually have 3 separate dimms across each.
