Was googling for guidance and stumbled into this forum! This is an awesome place!
I just had a new system built and would appreciate some guidance. My system is:
CPU: AMD Threadripper Pro 5965wx
Motherboard: ASUS Pro WS WRX80E-SAGE SE WIFI II
RAM: Kingston FURY Beast 16GB (1x16GB) DDR4 3200MHz CL16 Black Desktop Memory (KF432C16BB/16)
GPU: RTX 3090 24 GB
Here are couple of my questions:
Can I use 4x32GB RAM? or should I be looking to fill all 8 slots?
Can you suggest a 256GB RAM which works with this motherboard? I have been trying to find the ones in QVL but they are very very hard to find. A RAM with RGB would be great, if possible
I have a PSU with 1200W, hope that’s enough for this.
I also have a 128GB RAM (8x16GB) from my old machine (6 years old):
G.SKILL TridentZ RGB Series 128GB (8 x 16GB) DDR4 2933 (PC4 23400) Desktop Memory Model F4-2933C16Q2-128GTZRX
Would this work? It’s not on the QVL list though. Then if I decide to go with 128GB, then I can just save some money and stay with this.
Compatible combinations can be found in the board manual. It also shows which slots are preferred/supported if not using all 8 slots.
Otherwise…8x RDIMMs is probably the recommended way to do things. You payed for 8 channels after all. With 4 modules, you only get half the bandwidth but have 4 spare slots for future expansion.
Micron, Samsung and Kingston all have RDIMMs and at least one of them will be on the QVL. Capacities up to 64GB are no problem, so you can get to 512GB fairly easy and cheap with 8 modules.
Try and error. DDR4 memory is pin-compatible with any other DDR4 memory. I doubt it’s listed on the boards QVL and you may have to compromise on clock speed to get it working properly, I’m not sure on that. Maybe other owners of the board can help, as don’t have this board myself. But it supports standard DDR4 DIMMs as far as I’ve seen.
Thank you so much for the quick reply! Then 8x RDIMMs it is
Will check my old RAM and post how it went. The QVL has somewhat similar RAM from the same maker on list (F4-2666C16Q2-128GVK - 2666 - 16-16-16-36 - v1.2). Only difference is that my RAM is v1.35 and the speed is 2933. So will tinker a bit in BIOS and see if it will work or blow up in my face
I have 8x23gb Kingston Fury Renegade 3200 at 2600 ( the max with this cpu and 8 channels according to the manual )with a 3955wx, the same MB and nothing to report.
So I replaced the 64GB Kingston RAM and installed my 128GB G.Skill RAM.
It struggled to start at first, but finally went into windows and I ran a UserBenchmark and within a minute the system crashed. So I went into BIOS, changed the profile to D.O.C.P, changed the speed to 2666 and voltage to 1.2 (as shown in the QVL for the RAM from same maker), ran the UserBenchmark and it went well! Hope I did everything correct
Here are the results:
UserBenchmarks: Game 213%, Desk 103%, Work 320%
CPU: AMD Ryzen Threadripper PRO 5965WX 24-Cores - 99.5%
GPU: Nvidia RTX 3090 - 218.1%
SSD: Samsung 980 Pro NVMe PCIe M.2 2TB - 418%
SSD: Samsung 870 QVO 8TB - 103.9%
HDD: Seagate ST16000NE000-2RW103 16TB - 135.5%
RAM: G.SKILL F4 DDR4 2933 C16 8x16GB - 331.5%
MBD: Asus Pro WS WRX80E-SAGE SE WIFI II
Let me know your thoughts, and if there’s anything else I need to look at, just a bit nervous about the BIOS settings. Thanks!
I’d run a stress test. Running memory intensive workload for an hour. People like to use Prime95 (AXV2 hardcore mode) for that, but calculating Pi for 200b digits with y-cruncher works as well. I myself use y-cruncher whenever I test my machines. Also heats up the room if it’s cold.
Ah, yes, it crashed as soon as I started the Prime95 stress test, tried again, it held for about 3 minutes and then crashed again
I have ordered this 256GB RAM (128GB kits x 2) which is on the QVL: G.SKILL Trident Z Neo Series (Intel XMP) DDR4 RAM 128GB (4x32GB) 3200MT/s CL16-18-18-38 1.35V Desktop Computer Memory UDIMM (F4-3200C16Q-128GTZN).
This is arriving today, will try it out and see how it goes
I would definity not mind the room heating up, which would mean my system is not crashing and also beats the cold weather here in Vancouver!
Did you manage to get it working with 256GB RAM (128GB kits x 2) which is on the QVL: G.SKILL Trident Z Neo Series (Intel XMP) DDR4 RAM 128GB (4x32GB) 3200MT/s CL16-18-18-38 1.35V Desktop Computer Memory UDIMM (F4-3200C16Q-128GTZN)?
