Question Memory errors in OCCT

[quadrax]

Hello

I have a problem to achieve stability with 4x48 GB RAM, DDR5 6000MT/s
In OCCT i get error within 2 minutes (RAM Test selected, not cpu+ram)

My rig is :

CPU : AMD Ryzen 9 9950X3D (OC to 5.2GHz)
CPU Cooler : Arctic Liquid Freezer Pro - 360
RAM : 4x48 GB RAM - Kingston Fury ( all 4 sticks ), 6000 MHz, CL30
MB : ASUS Crosshair X870E Hero
PSU : Corsair RM1000x
SSD : 1x Samsung 2TB 9100 Pro, 1x Samsung 4TB 990 Pro
GPU : Gainward GeForce 5070 Ti Phoenix

So main problem is, to maintain memory stability (when i have 2 sticks, there was no problem). Probably IMC is little bit a worse than i thought. I dont know, if its possible to make it stable on that frequency. I tried many configurations and voltages. Nothing helped. Maybe i am doing something wrong, but i am not really sure about this.

Can someone help me, introduce something what i can try? Anyway BIOS for my motherboard is latest ( 1504 )

Thank you for your reply.

If you're having memory instabilities with 4 sticks of ram, then it's to do with either the second ram kit you dropped in or the integrated memory controller. You're on the latest BIOS version for your motherboard as far as I can see.

Perhaps try and lax the timings on the ram kit and see if stability returns or if downclocking the ram sticks brings said stability back.

How are you going about overclocking the ram? merely enabling AMD's E.X.P.O?

I am not using AMD Expo / Intel XMP,. I set up everything manually. Now i just testing with CL32 and it seems (for atm) stable, but need more testing so far. Anyway if there is problem, i can try lower frequency thats true. Voltage on IMC have no effect (at least in 4x48 GB RAM configuration), maybe it can do, but not so much as intended. Anyway 6000MHz is not overclocked (for the RAM itself, its their default speed)

I gave up. Removed that new RAM (kit) and going back to 96GB RAM.

Why not use XMP/ EXPO ? You can always make small changes to settings manually, Start testing with lower XMP/ EXPO and check for stability.
PS. 6000MHz is considered OC, RAM as well as IMC. Starting frequency (by JEDEC standard) for DDR is 4800MHz and IMC depending on configuration is

Max Memory Speed 2x1R
DDR5-5600 2x2R
DDR5-5600 4x1R
DDR5-3600 4x1R
DDR5-3600 4x2R

I just trying actually 5600MHz, and it seems (must knock to the table) stable, but is there any impact 6000 vs 5600MHz? As i saw, probably noit noticeable. Is this true? (in gaming, or loading apps). Thanks for the reply.

There's very little to no difference between those speeds in real life applications. At lower frequency should come lower latency so it kinda evens it up performance wise.

Thank you for your reply. I stick then to 5600MHz. Best regards, Arm0r!
