Question BSODs and Memory Issues on New Build - Need Advice

[Sunshinegoes]

Hello Tom's Hardware community,

I recently built my first PC and I'm experiencing some issues with my RAM that I could use help with. Here are the specs for my build:

- CPU: Intel Core i5-13600KF 3.5 GHz 14-Core Processor
- Cooling: Deepcool LS520 SE 85.85 CFM Liquid CPU Cooler
- Motherboard: Gigabyte Z790 AORUS ELITE AX ATX LGA1700 Motherboard
- RAM: TEAMGROUP T-Force Vulcan alpha 32 GB (2 x 16 GB) DDR5-6000 CL38 Memory
- Storage: TEAMGROUP MP33 2 TB M.2-2280 PCIe 3.0 X4 NVME Solid State Drive
- Graphics Card: PNY XLR8 Gaming VERTO EPIC-X RGB GeForce RTX 4090 24 GB Video Card
- Case: Lian Li O11 Dynamic EVO ATX Mid Tower Case
- Power Supply: Corsair RM850e (2023) 850 W 80+ Gold Certified Fully Modular ATX Power Supply
- Fans: 2x Deepcool FC120-3 IN 1 61.91 CFM 120 mm Fans 3-Pack

To clarify, I actually have 64 GB (4x16 GB) of RAM installed. But, I've encountered two BSODs (once in a month) which led me to suspect an issue with the memory. Running Memtest86 did reveal faults. I was advised online to turn off XMP (referred to as EXPO profile in my BIOS), which seemed to resolve the Memtest86 faults. However, now my memory speed has dropped from 6000 to 5200.

I've confirmed on the Gigabyte website that my motherboard does support this RAM, but I'm a bit lost interpreting a complex compatibility table.

I ran a Windows wmic command and here's what it sees:

Capacity	DeviceLocator	FormFactor	Manufacturer	MemoryType	PartNumber	SerialNumber	Speed
17179869184	Controller0-ChannelA-DIMM0	8	Team Group Inc	0	UD5-6000	01042F1A	5200
17179869184	Controller0-ChannelA-DIMM1	8	Team Group Inc	0	UD5-6000	01042F18	5200
17179869184	Controller1-ChannelA-DIMM0	8	Team Group Inc	0	UD5-6000	01042F24	5200
17179869184	Controller1-ChannelA-DIMM1	8	Team Group Inc	0	UD5-6000	01042F2E	5200

So, I'm hoping someone here can help me out with these questions:

1. Will the memory speed decrease from 6000 to 5200 significantly impact my FPS in games?
2. Should I consider purchasing new RAM? If so, what should I look for in terms of specs? Or would it be better to just remove 2x16GB sticks?
3. Is there anyone here who can help me make sense of the compatibility table?

I'm grateful for any advice or input you folks can offer. I've always found the expertise in this forum extremely helpful and am hoping to get to the bottom of this issue with your assistance.

Thanks in advance!

What BIOS version are you currently on for your motherboard?

To clarify, I actually have 64 GB (4x16 GB) of RAM installed.
If your system regains stability after removing two sticks of ram then later enabling X.M.P, then the issue could be that the memory controller on the processor doesn't want to work with the additional sticks or additional sticks with a higher ram frequency.

Hello Lutfij,

Thank you for the prompt response.

To answer your question, I'm currently running on BIOS version FB.
My motherboard has a revision number of 1.1.

To clarify, I haven't yet removed any sticks of RAM, because I was unsure about the root cause of the problem. Based on your suggestion, it seems like that could be a good next step to test.

I've checked the Gigabyte documentation, and it says the motherboard supports up to 4 x DDR5 DIMM sockets supporting up to 192 GB (48 GB single DIMM capacity) of system memory. I'm not certain how to check if the memory controller or processor can handle 64GB of RAM at this frequency. If there's a way to confirm this, I'd appreciate your guidance.

Thank you for your assistance. Looking forward to your reply.
