Corsair RMA replacement

[Substance]

I have 2 faulty modules of corsair dominator that I sent back to corsair and they have just sent me a message back saying

"We have received your RMA 1221660 which unfortunately is for an obsolete/discontinued product which is no longer available for direct replacement. Under our warranty policy we are able to offer you alternate replacement. Please confirm to us at your earliest convenience. Returned Product: TWIN2X2048-6400C4D G Returned Qty: 1 SET Potential/Alternate Replacement: TWIN2X2048-6400C4DHX G"

I already have 2 of the older modules in my pc that I bought at the same time as the 2 I sent back, Will the 2 new sticks be fully compatible with the 2 in my pc and still run in full dual channel?

Thanks, Mike

From what I can see your original memory is Dominator DDR2 PC6400 with timings of 4-4-4-12 operating at 2.1V:

What they are offering is XMS2 DDR2 PC6400 with timings of 4-4-4-12 operating at 2.1V:

Apart from looking completely different they seem identical in specification so should be OK.
