Rampage V - issue with memory

[rzbierski]

hello,
I have MB - Rampage V , and I have lot of issues with this MB.
Lot of bd code or bF, i'm frustrated because I spent lot of money. I have to swap memory in slot , restart PC by Hard Reset etc.
I have 8x8GB Ram - Fury HYPER DDR4 (HX426C15FB/8) - spec https://www.kingston.com/datasheets/HX426C15FB_8.pdf

Could You please help me ?? Maybe I have wrong RAM or maybe I have wrong settings in BIOS, if yes could someone help me with settings ??

Thank You,
Radek

The BD error is directly related to CPU System Agent Voltage. It just needs to be fine tuned. The voltage is different for every setup as the memory controller is on the CPU and not the motherboard.

At stock, there should be no need to adjust these values.

I use less than 0,85V SystemAgent Voltage for 7980XE and G.Skill 128GB 3200er CL14 KIT (load xmp only and it works out of the box).

I often read that combining Corsair Memory is difficult and it fits to my own experience with corsair memory since the old pentium 4 days..

Those values aren't applicable to this platform. For anything above stock, 8 modules and 128GB capacity on X99 can need anywhere in the region of 1.1 to 1.25v, sometimes more. Even then, not all CPU will be capable. However, there should be no issues passing POST stress tests at complete optimised defaults.

At stock, yes that is true. But he is running 2 sets and not one. That's a lot more tricky to get stable.

With two kits at that capacity running anything above stock will require a lot of tuning including most likely relaxing a lot of the sub-timings. There are a great multitude of reasons why combining memory kits is not recommended, that type of tuning is not for everyone.

What voltage have you gone up to for the System Agent Voltage.

@rzbierski So,when you put all 8 sticks and use MEMOK! feature,what is happening?
