Strange Memory Issues

[ASWprime]

I'm having this very strange issue with my memory. I bought two new sticks, these ones in fact, and paired them with my current memory. I KNOW, I know, don't mix brands, but I did it because the two sets have the same rated frequency and similar timings though not identical. Regardless, I installed the new memory and my PC did not boot, so I took out the new memory and re-seated the old only to be met with a boot failure and being kicked to the bios. No matter what I did I could not get my PC to boot with even just the old RAM, UNTIL I set the frequency to 2133MHz. The highest speed I can get out of the kit as of now is 2800MHz, so basically the memory will not run at its rated speed now after installing an uninstalling that new memory. Any ideas?

 

Things I have tried:

- Updating to newest BIOS/resetting BIOS to defaults and then changing the frequency

- Setting memory speed via XMP and manually

 

And some other system specs just in case it helps:

CPU: 8700k @ 4.6GHz

Mobo: Gigabyte Z370P-D3

PSU: Raidmax Cobra 1000W 80+ Gold

Are you using 4 sticks now?

 

resetting the BIOS to defaults (an option in the BIOS) is different from clearing CMOS, the former one is far less functional.

try to increase dram  voltage a bit to 1.4. and set frequency to 2933. it might work. if not, be happy with 2800, it's not going to make a big difference going from 2800 to 3000

No I'm just using the two that I was using before, the Viper kit specifically and alright I'll give a clear CMOS a try later, have to remove my GPU to get at the battery.

there are two pins on the motherboard which if shorted with a metal object will clear cmos. that is the correct way of doing it, not by removing the battery.

Oh, alright nice, I'll do that instead, and as far as your previous comment I upped the DRAM voltage to 1.4V and I did successfully get into windows. I then restarted to make sure and now it again will not boot at 3000MHz even at 1.4V.
