This process seems straightforward and not overly complicated. I’ve used compatible systems like the IBM PC XT, 80286, 80386, and Pentium before. When I connect a memory stick to older machines (especially starting with the 80386 with SDRAM), the BIOS displays the correct memory size in MB. I’m curious about what’s happening here.
The final 16mb of memory remained intact. It stayed available in the system. The BIOS isn't detecting the last 16mb since the maximum supported size was set, and the number is just approximated. This has no significance.
No, the FX processors don't have "trouble" with all slots populated. No, the amount isn't "rounded" like ShrimpBrime says... it's just not included in the reported value for some reason. It's a quirk of the BIOS, which probably reserves 16 MB for something, for some onboard hardware which probably was removed from that model or from a specific revision. Could be a simple case of the BIOS reserving 16 MB as if you have a processor that has integrated graphics, and 16 MB is the minimum it could reserve for video card memory. Basically, Windows reports what the BIOS reports, and the BIOS simply decided to report your memory amount, minus 16 MB. Even when the whole amount is reported by the BIOS, parts of the memory are reserved by hardware for various functions like buffers, for example the USB controller will reserve a few MB, the network controller will reserve a small chunk of ram that's exclusive for it and can't be used by other things and so on. So it's not a big deal that your full ram amount isn't shown... it's just a bug that doesn't harm anyone but stupid applications which may have minimum requirement to have at least 32786 MB of memory installed (never heard of one)
It might not be perfectly rounded. Windows sometimes misreports squat on half of the time. Memory usage is even more inconsistent—frequency matters more than absolute numbers. CPU performance is usually reliable, though. AMD’s unusual algorithms can affect temperature readings, especially for chips over 40°C. I wonder if @Beerzerker has any insights, particularly about his preferred platforms.
