installed two more sticks of ram and now my computer hates me

[auggiepoo]

Hi all, below are my pc specs, hope you can help me fix this issue I've just run into!

 

MOBO: MSI MPG Z790 EDGE WIFI

CPU: I9 14900K

GPU: NVIDIA 4070TI

RAM: CORSAIR VENGEANCE 32GB DDR5 (Now 64GB with the two new sticks)

CPU COOLER: Arctic Liquid Freezer III

PSU: 850W ATX 80 PLUS GOLD

 

Ordered some extra ram recently after noticing on some more demanding games that a high percentage was being used... definitely not a necessary upgrade but for some peace of mind and aesthetic reasons I made the purchase. When I first upgraded my mobo and got ddr5, I wasn't able to extract more than the default MHz without running into issues; never ran into issues at this frequency so I just left it be and enjoyed a working pc. Default is 4000MHz, the Corsair ram I have is rated at 7200MHz; I know that you can't always get what the package advertises but I couldn't even get close. I tried messing with it a bit today after installing the two additional sticks, and now even at default settings my PC is crashing when booting a game. I've tried some troubleshooting, but I'm at the end of my expertise.

 

If XMP is enabled, I will receive a RAM fail error. If I manually adjust the frequency without XMP, even if it's only to the default 4000MHz, I run into the same error. I've gone through a couple of solutions others have found that worked, but sadly hasn't for me.

 

Any ideas would be greatly appreciated, if I'm missing any info that would be helpful, please let me know. Thanks!

What are the exact model numbers of both kits you're using? 

 

That said, 4 sticks of DDR5 is known to be an absolute nightmare to get working properly, so this isn't exactly a surprise. The highest I've seen anyone get with 4x16GB is 7200, and I don't exactly trust their stress testing procedures. The highest speed that I actually somewhat trust their stress testing is usually around 6000-6400, and there are quite a lot of people stuck at 3600-4000MT/s if it even works at all. In order to get those higher speeds, you generally need to play around with the BIOS revision until you find one that works with it, but given you've got a 14900K and IIRC that board only has one BIOS on the microcode that doesn't kill it, this isn't really an option. If playing with the BIOS isn't an option, you have to start manually messing with memory settings to have a chance of getting it to work, and if you don't know what you're doing this will take forever (even if you do know what you're doing it still takes quite a while). 

 

Basically, if you didn't actually need the extra capacity (just because you're using 80% of your RAM doesn't mean you're running out, unused RAM is wasted RAM), remove those two new sticks and return them, they're not worth having in your system. If you do really need the capacity, return the new kit, buy a 2x32GB kit, and resell the old kit. As far as I'm concerned, your motherboard shouldn't even have those two extra RAM slots because of how prevalent of an issue this is with DDR5.
