Team Group DDR4 and Heat Spreader Removal - Timings

post #1 of 4
Thread Starter 
Hey guys!



Purchased some team group DDR4 16GB 3600 from a member here on OCN. Great deal! Here's a slight dilemma, I need to remove the heatsink on the memory because its going to be too tall for my ITX cooler. So basically I've read and read guides to removing heat spreaders, pretty much have that figured out. Go slow and use a hairdryer and I should be good. Anyone have experience with bare DDR4? With the memory XMP profile for 3600 speed I'm considering downclocking it to 3200 and getting better timings and saving on some heat generation... I know Sky Lake loves high memory clocks but I also don't want to burn up the memory...

How is the brand? Haven't really heard much about Team Group. Chinese company?
It looks like some DDR4 modules are Micron or Nanya chips so I'm hoping I get Micron just for reliability sake...and I have some skin in the game with Micron and their stock..lol thumb.gif

Team's been around a while. I've bought several dozen memory modules from them. They've all been fine. They seem to offer the cheapest memory among all the manufacturers on Newegg.ca.

As for the speed, 3600 is the default XMP profile. It's not gonna burn out if you run it at specs.

Heat Spreader came off just fine!

Now for memory timings! WOW this Row Refresh Cycle Time seems SUPER high! I've upped the voltage to 1.375V from 1.35 XMP. I'm hoping I can drop the RRCT down to maybe ~400 something...


I know the timing's aren't great but they're still pretty quick for 3600 DDR4. I can't find ANYTHING on DDR4 Row Refresh Cycle Time rates...

630 tRFC at 3600MHz is the same real time as 373 tRFC at 2133MHz, 560 at 3200MHz, etc. Can go from there. You're free to attempt to reduce tRFC or increase tREFI to reduce the impact of the higher tRFC.
