Windows and BIOS recognize every RAM module, yet only half functions properly...
Speccy shared their setup details on their site. They have four 8GB DDR4 modules on an MSI B350 Tomahawk with a Ryzen 7 2700X, but only half is functional. BIOS and Windows RAM reports are linked. They've updated the BIOS, reset CMOS, verified Windows 10 boot memory limits, confirmed RAM compatibility, and tested each stick separately. They're seeking advice from the community.
Remove your cooler and CPU, ensuring no bent pins remain. Once confirmed, reinstall them carefully, applying even pressure without over-tightening the mounting screws. If this doesn't resolve the issue, inspect your RAM slots one at a time. Verify each slot with a single stick, and test your channels using two sticks (follow the dual-channel manual). Re-seating the CPU may also resolve the problem, as previous discussions suggest this fix works.
Consider contacting the mobile manufacturer to report the problem. Some users find that re-seating the CPU resolves the issue, though it may involve hassle with returns and other complications. If that doesn't work, there might be additional problems with the motherboard or CPU itself. Make sure the pins are clean and the socket is secure before proceeding with an RMA.
The term "usable" can vary—does it refer to performance, functionality, or something else? If Windows shows memory stats, it doesn’t necessarily mean it’s actively in use; it could be idle or background processes.
I understand your questions. Are all four sticks identical? Did you verify the CMOS reset without applying the memory profile? What occurs when you boot with two sticks in channel B? And if you use one stick in channel A and another in channel B, what happens?
No worries! Thanks for taking the time to help out- 1) Yes, all four are exactly the same, all brand new: https://www.amazon.com/gp/product/B015FX...UTF8&psc=1 2) Yes, I only loaded default settings, no XMP profiles or anything like that. 3) Haven't tested yet, as this would force single channel, no? I'll test it and get back to you though. 4) I tried with only two sticks, in DIMMA2 and DIMMB2, per manual suggestion. Same exact issue. Recognizes both in BIOS (8GB each), but DRAM size is only 8GB. I thought the issue might be the two kits together, but it seems with even just 1 kit, it doesn't work.
The aim was to determine if the problem is unique to duel channel mode. If running two sticks in single-channel mode works, it suggests an issue with that mode. Examine the CPU for any bent pens; if everything is intact, consider returning the board. Reminder: I should have included this in my initial suggestions, but haven’t you verified each slot separately? You mentioned testing all sticks individually—true.
Thanks for the assistance. I'm planning to buy a B450 tomahawk at Best Buy today and check if it helps.
