RVE 6850K Won't Recognize All Memory Sticks and Mouse Freeze

[AndyM5]

My RVE is acting really odd with the 6850K which worked perfectly with the 5930K.
My G502 often freeze or dropped in desktop and require replug to make it back on.
And with stock setting the board only recognize 4GB out of the 16GB and only with added Vcore and SA voltage the board can recognize still only 8 out of the 16. Nothing else will let the system work with 16 although CPUZ sees all 16.

X99 has been the most glitchy platform I have worked with but this RVE is beyond me.
I'm on the newest 3501 bios, should I RMA or keep trying other tweaks u guys may suggest?

Thanks in advance!*

hi Andy
Have You tried changing the different PSu for Stress testing ?

I'm running a AX1200, I don't see it's making anything odd.
But I did order a EVGA Supernova 750W G3 to replace the aging unit.

Will report back.

Sounds like instability.

1) Reset the CMOS

2) Reseat all memory modules

3) Reseat the CPU checking for any bent pins in the process - reseat and check for even mounting pressure

Will try that now, thank you!

Did not expect it to work but reseated the CPU works.
Thanks! Rep+.

No problem. Over-tightening can cause these things on occasion

Will have to try that, I just upgraded to a 32GB GSkill DDR4-3000 kit which is also on the QVL list.
Similar issue only recognized 24GB out of the 32GB.

Already tried rest bios and reseated Ram and loose the CPU cooler.
Only thing left to do is to reseated the CPU again.

Boy, these X99 boards are beyond me.

Tried seated the CPU and RAM. Back to the square one now, still seeing only 24GB out of 32GB.
The QVL 32GB kit F4-3000C15Q-32GRK will NOT show the full kit in BIOS and windows but does recognized all 32gb by CPUZ.
Should I RMA the board?

Test each stick individually in slot D1. Also you can try removing the motherboard from the enclosure and testing.
