How to test ram that the board addresses for onboard graphics?

[john_wayne]

Asus rog strix g10dk amd ryzen 5 3400g with radeon vega graphics. 16gb ram installed, but only 13.9gb available (due to ram allocated to the onboard graphics). Even memtest86 can only see the 13.9gb. I keep getting irq_not_less_or_equal and nt_wrong_symbols bsods. How do I test that other 2.1gb of ram? I hate to buy all new ram when I dont know if there are other component issues.

Does the system also have a discrete GPU? If so, you should be able to disable the iGPU in the BIOS to make the RAM available to the OS instead.

iirc there's always at least 500mb or so reserved, even if you disable the iGPU.

 

But that would still be an improvement, I guess

Ok,  but you are already getting errors, so if the other 2.1gb get no errors, what would that change?

OP didn't say whether Memtest86 actually found any hardware issues. A quick Google suggests that "irq_not_less_or_equal" is typically the result of a faulty driver. It would probably make sense to rule that out first, by booting into a live environment and do some stability tests there to rule our the current OS install.

Oh, right they didn't actually.

 

Yeah, I got that error with a dodgy BIOS , crashes never really totally vanished even after several updates, only buying different ram eventually fixed it (that was on a b350 board)

thanks all. It's a B550 variant. Doesnt seem to be the full fat BIOS. Can't disable iGPU. Ran 4 pass tests 3x, no errors with memtest86. My research was telling me the nt_wrong_symbols was indicative of ram issues, but that was wrong. I was able to correct nt_wrong_symbols by reloading symbols into windbg. I finally got the report that the driver for realtek 8822C was at fault (WLAN/bluetooth card). I had WLAN disabled, but use BT regular. Realtek's site is about useless, and ASUS/ROG only listed an older driver. Used AI to find a newer driver for an ASUS TUF gaming PC. Uninstalled the BT driver (with driver removal) and installed the new driver. Configured VERIFIER to watch the BT driver, so when/if on next BSOD I should get a more detailed .dmp with info of what led to the BSOD. Fixing Win11 on a prebuilt machine is starting to feel like debugging linux on a custom build. Ugh, I bought a new to me prebuilt just so everything would just work and facilitate the move to Win11..

Further update: continued vague bsods after replacing wlan/bt module & adapter. Swapped the ram sticks physically and memtest86 found errors. So the iGPU was in fact masking the bad ram. (Disabling the iGPU in windows because stripped down asus bios couldnt - didnt improve bsod situation). Buying new ram now, and a later upgrade will be a processor without an iGPU.
