Corsair Domiinator Platinums Blaze away at high temperatures

People say you do not have to worry about ram temperatures, but never explain exactly why that is exactly?

My Patriot DDR4 ram failed after 8 months; the memory had an occasional error now and then. The temperature never deviated a lot from 40C and that was with tin heat sinks.

I purchased Corsair Dominator Platinum CMD16GX4M2B3000C15. They have heavy duty heat sinks and are recommended for the Maximus VIII Ranger motherboard. I have no problems with the motherboard except the bios go bonkers with bad ram installed. But at least it ran Memtest64+.

The 1st set (2x16G) ran at 40C (module 1) and 99C (module 2). I guess 99C is probably bad?

I took it back to the store for an exchange?

The latest set is running at 77C (module 1) and 60C (module 2). The store says these temperatures are excellent.

I am running the Ram at 2133 Mhz right now. I ran memTest64+ for two passes at 3000 Mhz and it passed.

Should I take it back to the store or would buying an air cooler for the top of the DDR4 actually do anything. Some people take the metal handle off the top, which covers the heat fingers and mount air coolers over the top.

One kid pulled his ram apart, used artic silver and some kind of paper, but never gave any details about why and what the benefit was, only how he did it. The adhesive paper Corsair uses looks like an insulator to me.

Four sticks have had four different temperatures, 40C, 99C, 77C and 60C. Sounds like a manufacturing issue?

This is the first time we've seen an issue like this. What I'd like to do is have you process an RMA direct with Corsair so we can get the units back and analyze them. Please submit a ticket through our support site and then PM me your ticket number so I can notify the Technical Support rep so we make sure this gets taken care of promptly. If you can, also send me photos of the spec label on both modules so I have this information as well.

Have you tried installing each module individually in the first slot and tested to see what their temps are? Try that, and compare the results. You might be able to try the second slot on your board as well to check if the issue follows the module or the slot on the board.

The temperatures are not for all four sticks concurrently, but rather each stick of ram has its own characteristic temperature. I suspect that if the slots on my motherboard were bad then all three sets would have had similar results than being so dis-similar. I am only using slots DIMM_A2 and DIMM_B2 on the Maximus VIII Ranger motherboard because I have only ever used 2 sticks of ram. I did switch slots on the Patriot RAM but they both ran at the same temperatures or 40C. ASUS(R) Intel(R) Extreme Tuning Utility Benchmark test cause the DDR temperatures to go up 2C.

I guess that because Corsair Nick recommended returning the DDR4 to Corsair, it means that high temperatures on RAM are indeed bad.

Corsair sent a prepaid 3 day-ground UPS label (bit map) with the return address. I had to pay 7 dollars for computer access, printing and an envelope.

I sent the DDR4 out on Wednesday Aug 9, 2017 and it arrived Monday Aug 14, 2017. 2 days for the weekend I guess.
Corsair apparently works fast and it came back on Thursday, Aug 14, 2017.

I put the RAM in and it passed one pass of MemTest64+ aok.
Corsair Link 4.8.0.82 reports the RAM are running at 33.3 and 33.5 C at the rated speed of 2133 Mhz.
note: the OC speed is 3000 Mhz.

I don't know if I want to OC or not, but it is an option.

I noticed Diagnostic software sometimes fails to pick up DDR4 temperatures, but eventually does?

Corsair Link and CPUID both report the same temperatures of 34C.
