Installing new RAM causes pc to not boot

Draconid

Hi, this is my system https://uk.pcpartpicker.com/list/pmLzrr, I wanted to upgrade to 32gb ram, so I bought this https://www.ebay.co.uk/itm/326280612436 (2x8 3600mhz of Gskill Neo trident z memory,) its CL18 whereas my current kit is CL17. I presumed it should be fine to mix both of these RAM kits together, however whenever I try and boot my system with both kits installed (and I have ensured several times that the RAM is seated correctly) my computer won't boot, but if 1 set is installed at a time they both work, just not together. I've tried different seating combinations and even disabled XMP mode on my MOBO, are there any suggestions on how to get these kits to work together or is there something I'm doing wrong? Thank you.

Clear CMOS/BIOS.

 

Drop the speed to like 2400Mhz with loose timings and work your way up. Mixing kits often works out but can cause issues.

People never go out of business.

If you're still in the return window for that 2x8 kit, I'd send it back and just get a 2x16 kit and keep the current 8s as cold spares. Never hurts to have RAM lying around
PS, you have reminded me that I need to grab some more because I ran out of spares 😛

I'll try this and report back if it works or not

I bought them used, so I wont be able to return them sadly, I'll just have to re-sell them if this doesn't work out

Probably because the C17's are most likely Samsung IC's and the C18's are some form of Hynix IC's. Totally different under the hood so they won't work together very well if at all. Maybe at 2133/2400 JEDEC but not any XMP speeds.

yes, when mixing rams with speeds, CL, brands, etc. the more mix and less identicality, the more chance of imbalance or straight up the things not working at all, or not working in OC
