Ram/Ram slots acting up

System Specs

Motherboard - MSI mag X570 tomahawk  WIFI (MS-7C84)

CPU - Ryzen 3700x

GPU - gigabyte RTX 3070

boot SSD - WD_black sn750 250GB

(OG ram)Gskill tridentZ rgb 2x8gb ddr4-3600 cl18

(new ram) Gskill tridentZ neo 2x8gb ddr4-3600 cl16

PSU - Segotep 750w gold+ 

my issue started a few days ago when I booted into a game of rust, started lagging out very badly and noticed the whole system was pretty laggy too when I tabbed out, task manager said I was at 90% memory usage(7500MB) with no other programs running in the background, I tested with memtest86 and user-benchmark and got some results which I was told where not great, like only half my ram being free to use. After running a few memtest86 tests my PC refused to boot and lit up my dram light, and after re slotting a couple times it tried very hard to “diagnose” itself and then gave me an option to recover from a previous windows state it also gave me these errors (SESSION1_INITIALIZATION_FAILED) - (SYSTEM_THREAD_EXCEPTION_NOT_HANDLED), so I figured it was the ram and replaced it. 

With the new ram I still had to restore windows and got a few BSOD well trying to restore it like (BAD_SYSTEM_CONFIG_INFO)(DRIVER_POWER_STATE_FAILURE) after i kept trying to get it to restore, it seemed to work okay except for everything on user benchmark where it still said I only had 8 of 16 gigs free. So I decided to test my slots to make sure they were all working using 1 stick of the new ram. 1 stick works perfectly fine in all slots, the other new stick refuses to boot in any slot and turns on my dram motherboard light. Also when its in slot 2 on my motherboard it tries to power up, fails and then powers up fully again. Now I cant use both sticks without the dram light coming on.(yes they are in the right slots 2 and 4 per MSI manual and xmp is on)

Sorry for the long post, i can post the memtest86 results and user benchmark if requested, I also haven't tried the old ram out because I would really like to not have to restore my system again if that's what actually caused it. Anyone have any idea whats going on here, did I just get a bad second set of ram?, are there any other tests I could do that would point me in the right direction?

thanks in Advance - Kyle

edit: 2 of the BSOD where from when the old ram was in, they didn't all pop up with the second set, sorry its been a long couple days of trying to figure this out

Well your text color sucks to read on darkmode lol.

 

Sounds like your CPU REALLY does not like the CL16 ram, and you should  probably stick with 3600 cl18 and see if that helps. If the slots are still not working with the old ones, then you may have some dead channels on the IMC of the CPU or the motherboard faulted for some rason.
