IMHO, heatspreaders on RAM make sense WHEN high speed RAM is being used. Everyone looks at server RAM and sees no heatsink…there is a common reason for that. Those DRAM modules ARE NOT running at 3600Mhz or faster. Those are more likely to be 2133, 2400 or 2666 if it is DDR4. and 1333 or 1600 if it is DDR3. The higher clocked the RAM is, the more prone to heat issues they are. If it is a legit metal heatsink with a thermal pad, it is functional. If it is not…it is cosmetic.
I have found actual servers WITH heatsinks on their RAM. That RAM is running very hard workloads that tax the RAM heavily. The last thing you want on a server is unstable RAM.
A huge bank of 12000RPM fans pushing 14CFM (0.4m³/minute) each?
there is that too
I think it was Ryzen 1 times but Wendell did not that he was having trouble keeping a RAM overclock stable and worked out that it was the 24pin causing some sort of interference. This was a surprise to him as well.
