Hi guys and gals, long time reader first time poster. I'm a bit confused and have run out of ideas here. Have searched but havent found a resolution.
But first here are some humble system specs:
AMD Phenom II X4 965 Black Edition - Asus M5A78L-M LX V2 Motherboard - Silverstone Tundra watercooler - 8gb G-Skill Ares F3-1600C8D ram (2x4gb) - Asus GeForce GTX1050Ti - CoolerMaster V550 PSU
I recently got a used FX-8300 cpu and installed it, but when posting bios only shows 4gb of ram installed instead of the actual 8gb. Put the Phenom back in and system returns to normal. The motherboard supports the FX processor and has latest bios, it only has two ram slots and the second slot B1 seems inactive. I've swapped the sticks over with same result, it boots with one stick in slot A1 but wont boot with a single stick in slot B1 (not sure if it would anyway but hey i tried) In Windows 10 it says installed memory is 16gb but only 4gb available for use.
Have also tried: Bios update, clear CMOS, removed battery for 10 mins, re-seated ram, re-seated cpu (checked for bent or damaged pins) checked for shorts, checked mounting of cooler (not too tight or loose) increase DRAM voltage, set timings manually, reset to auto.
I'm thinking either the memory controller onboard the cpu could be faulty, or maybe there is a fault in the motherboard somewhere, has anybody seen this before? Just wondering what to do next (return the FX cpu or replace the low end mobo) Sorry for the long winded post but trying to provide ample details.
Any help would be greatly appreciated!
