Dell Precision T3500 Non-optimal memory population detected
every time i turn on my computer, i get the Non-optimal memory population detected and before I was able to simply press the F1 key to just go to windows and everything be perfectly fine. But now, I am unable to press the F1 key to bypass this, I also can’t press any other keys. Before this warning I am able to press F2 to get into setup utility but unable to do so on the warning screen. If I press any key a number of times, it just makes a beep noise and nothing happens. I have tried to bypass this warning by turning off Keyboard Errors in setup utility, but I still get the same message, unable to bypass it. This only gets rid of the Strike the F1 key to continue part. Any help?

Have you upgraded the RAM on your system lately? This forum post and chart within may help.

Are you unable to access BIOS upon startup? Either way...
No guarantees, but if it hasn't been done in the last 5 years, replace the CMOS battery. It can often be the place to start. A bad battery can cause all sorts of seemingly unrelated problems.
I'm hoping 1 of 2 things happen and I've seen it this forum - It'll either work or throw a different error code that sometimes more accurate and understandable.
2nd - You might have to reseat the RAM one by one until the error repeats.

@bradthetechnut
last time i was playing game and suddenly I shows the windows that your pc ran into problem and restart by itself and while restarting after BIOS loading it shows memory failure in DIMM 2 and open with any beeping but now I can only use 8Gb out of 12 gb so I shutdown it and replace memory in DIMM2 so it again shows the same error although I changed the RAM(memory), so I shutdown again and repeat the replacing memory process but end up with same result (memory error in DIMM 2). I shutdown again and try to rum system only putting memory in DIMM 2 and after that my computer start beeping sometimes after BIOS and sometimes in the end of BIOS loading screen. Please give a valid solution I really need it.

I'm going to take it you also have a T3500.
Did you already replace the motherboard battery?
We can't diagnose PC's from here but can give suggestions and typical solutions.
Only 2 things I've heard of fixing a bad DIMM slot. 1. Try reseating the CPU. Replace if that doesn't work. 2. Replace the motherboard.
With the T3500 being older, up to you how much you want to put into it.
