Purpose:
"I want this thread to exist so we can all shear the beauty and power of most overlooked component in the rig which is" the memory,show what we use on daily bases and bench-marking, help others to make the right decision when buying RAM ..and since some of us can't stop buying/blowing more money on ram a place to show what we roll

Rules:
If you have more than 2 sets of RAM (DDR2/DDR3/DDR4) ;
-post pics of your memory sets
- make, model number
- your favorite bench and 24/7 RAM
if you willing to go extra mile;
-post the picture of bare module (heatsink off)
-post your Maxxmem,Super PI,Aida benchmarks

* Dont worry too much about CPU on subzero it probably is not required in most circumstances, CPU on air/water should be fine for tight legacy ICs subzero, I can train/bench 2700 6-9-6 with CPU on water no problems
* Get a baseline on air that you know works but is on the edge, when you mount all your gear subzero make sure that baseline is good, this will save you alot of time
* When you are pulling down you will often need to retrain memory, sometimes around 0 degrees, sometimes around -30, but expect some not exacts as you are pulling down, going into bios and changing 1 memory timing will force retrain
* Use mrc disable when you have your settings locked in, disable mrc re-train on boards that support it, this will give you longer more reliable subzero sessions, more time benching, less troubleshooting
* Watch how much grease you have around your ram slots, if you are having issues, clean the ram with circuit board cleaner
* If you want to train CAS6 TWRRD_DR must be 5 or looser; I may be possible to train cas6 with TWRRD_DR 4, but so far I have not been able to do it
