[QUOTE="pigoo3, post: 1935198, member: 56379"] Yes those temps are higher (an hour of video editing with Final Cut will do that of course).:) Back in post #1 you mentioned doing an update on this computer (I'm assuming an OS or other software update...but not 100% sure). Before this update I'm assuming everything was running fine...and I'm going to bet the RAM temps (before the update)...were similar to what they are now. Basically what I'm thinking...the update & dead RAM stick...are just a coincidence. In theory...if the update was not done...the stick of RAM would still have gone kaput. Just coincidence when the update was done. If heat/high temps were an issue...and assuming you've been running this computer for a long time...then I would think the RAM would have "kicked the bucket" before this. Electronics usually don't tolerate high temps for very long (if above what they're supposed to run at). Does the RAM with heatsinks run cooler...maybe. In theory if everything is exactly the same between two computers...the RAM with heatsinks should run cooler (but is the difference significant). Might only be a few degree's. I know you mentioned trying the dead stick of RAM in other RAM slots (good idea)...and it still shows up "dead". I would also try a good stick of RAM in the RAM slot the "dead" RAM stick came from...just to be 100% sure there's nothing wrong with that RAM slot. I'm thinking if you need 128GB of RAM...get another 16GB stick of RAM...install it...and see what happens. - Nick p.s. I also just checked OWC (macsales.com). If you head there...you'll see that the RAM OWC is selling for Mac Pro 5,1's (2010 & 2012 models)...is RAM without heatsinks/heat spreaders. This would indicate to me that the heatsinks probably not important (I'm sure OWC knows more about this than us). And Like I mentioned in an earlier post...one of my Mac Pro 5,1's has OWC RAM...without heatsinks...and it runs fine. [/QUOTE]
