X399 Taichi - Needing 4x16 upgradeable to 8x16

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello everyone. Long time listener, first time caller. I'm currently in search of QVL memory that can be bought and installed as 64GB now but later upgradeable to 128GB, if necessary.
I currently have installed a 64GB HyperX kit (HX426C16FBK4/64) which appears to be working just fine, but am no expert when it comes to QVL lists and cannot determine the question (1) of whether or not it would be possible to add a second of the same kit to achieve 128GB. I built systems back in the day but specs/considerations appear to have changed significantly and are more sensitive these days.

If I'm unable to add a second kit, I see that the HyperX Predator - HX430C15PB3K8/128 is listed as compatible at 8 x16GB. If that's the case, a question of mine (2) is if only half of this kit could be used for 64GB? Then, if that's the case, (3) how do I go about finding this same stick available in a 64GB kit since the product number itself denotes a 128GB kit? 

I'm losing sleep over this specific question and would REALLY appreciate an expert opinion.

Current Build:
X399 Taichi - Memory QVL
1900x AMD Ryzen Threadripper - LINK
64GB Kingston HyperX RAM - LINK
4x 2TB FireCuda HDD - LINK

	try changing the product number in part code from 128 to 64 but ! theres less chance that 8 sticks will run at same or similar speed and timings and EASE that 4 sticks will run

	Thank you! I had done that for other models but not this. That?�s my answer. Now I just need to find a /64!at something near half or the /128 :) Off to battle the impossible task of installing windows on a RAID now.
