CPU CACHE MEMORY 4.2 4.2 2133 - STABLE 4.2 3.0 3200 - STABLE 4.2 4.2 3200 - UNSTABLE (already push 0.1v more for cpu and cache)
I have already try push all the voltages in BIOS and digi+ setting to extreme, but it still can not pass HCI memtest 600%. Try VCCSA from 0.85v to 1.4v and VCCIO 1.05v to 1.4v no significant effect.
And there is a strange thing, if I manual setting the ram timing and left "REF Cycle time" for auto, the memtest will error in seconds. If I set the same timing with auto value, I can pass the memtest for at least 100%, it's very weird.
Another is I can't boot into OS if I push the ram voltage from 1.35 to 1.36 even 1.40, but I can boot with 1.35v.
Is that bios' problem? Please help me to solve the problem, I just want to run the memory at advertised frequency.
Kidd232, You don't list your Video card for reference but your power supply is about minimum for an X-99 build, Dram voltage up to 1.5 hasn't bothered my X-99 boards but I use 1.4 to 1.425 for 3200MHZ and above, VCSSA 1.0 to 1.2 range sometimes higher is worse, CPU VCIIO 1.1 to 1.2 Have you raised the cache voltage about 1.3 volts max is common, the 16GB sticks may be harder to get stable then 8GB sticks but you did pick some very good modules, the Gskill kits with flat 14-14-14 timings are the easiest to work with
