today i upgraded my memory in my 8200 from 8 gigabits(2x4)PC3 12800-1333 to 16 gigabits(4x4)PC3 12800-1600 which was the recommended upgrade from 4 different computer memory sellers. But the system,although faster, still only says it has only 8 gig's and the speed still says 1333 MHz. I'm running windows 8.1 professional 64 bit . according to HP this unit will run 32 gigabits of DDR3 memory. i was going to get the 4x 8 gigabit chips to max the memory out, but if it doesn't read/acknowledge the 16 gigabits that i just upgraded it to , i'm glad i didn't get them yet .the BIOS is upgraded to the latest version J01;2011. is there something that needs to be change in the set up to allow the memory to read whats in it ,or some download from HP that opens the system to allow the maximum memory to show correctly? any help would be great .

Welcome back to the forum.
I am not a HP employee.
Your PC's BIOS and the operating system should see 16 GBs of memory.
Try reseating the new memory modules. Try swapping the modules. Try only the new modules in the memory slots occupied by the HP factory modules.
Incompatible memory usually causes a POST error.
Very strange. the new modules should work if they are compatible.

It is sad when you get a "wrong turn". According to HP Service Manual dated 2011, it support 1333, not 1600. It also states the SFF model supports 4x4GB as a max. See page 2-7 and 3-5.
Note: Vendors have an escape clause called " *Not to exceed manufacturer supported memory ".

well, according to the HP tech i spoke with ,this M58P 7484 CTO desktop will run up to 32 gigs of pc3 memory ,either 1333 or the 1600 upgraded memory is what the recommend for the 6200 6300 series machines. unlike microsoft, they weren't willing to take over the machine remotely and see if they could find the trouble and correct it. the 4 gig chips that came in this were PC3 10600 U's. the replacements for the first one were DDR3 PC3 12800 1600 Mhz and the are working fine. and the supported manufacturer's memory is Ma 32 gigabits DDR3 PC3 memory . the new Cyrix modules i got (16 gigs 4x4) are working fine ,the machine speed now is 2 to 3 times faster than it was with the old 4's, but it is only registering 8 gigabits .
The tech thought perhaps the bios or the CPU was locked and that could be why it didn't register the 16 full gigabits in the system. some of the old IBM think centres had that trouble when install higher memory, but then IBM had an app to open it up so that one could run up to 4 gigs of DDR PC2100 unbuffered memory in it,there was also an app to unblock it to run higher HDD capacity drives also . my first one came with 512 gigs and a 8- gigabit HDD . The HP runs fine with the new modules, no stalls or freeze ups, but it doesnt recognize 16 gigabits of memory only 8. Crucial also informed me that the upgrade for the elite 6200 and 6300's was P C3 12800 x 1600 speed. and that it would take up to 32 gigabits of that upgraded memory. perhaps they and HP were both wrong . If you could possibly check the manuel again , i would greatly appreciate it very much. Here are the machine specifications.
