So this old rig has been chugging along happily for 5+ years now with an unlocked core. Back in the day I ran mprime for several days to test stability, it was good.

Anyway, I noticed that lately I've been running out of RAM, so I doubled it to 16 gigs. Suddenly, my system would POST 1 in 5 times. I upgraded my BIOS on Asrock 870 extreme 3, wiped the CMOS, and unlocked the core, and continued to have the same problem. So, I relocked that extra core, and everything works fine.

What happened?! Did adding ram expose some latent defect in that extra core?! If I mess around with voltages, or whatever, is there any chance I could get that core back? It doesn't matter that much, because I plan to upgrade when Zen comes out, but I'd still like to see what you guys have to say about it.

PS:
The RAM that I've upgraded to is ballistix 1600 1.5v. I've run memtest on it overnight, and it gave no errors. My old mem was g.skill (it looked fancier)
 
Solution


first of are you running 2 ram sticks from diffrent makes as that can mess up the performance due to diffrent speeds and cl timings and voltage

next were you always running the memory at 1600mhz ? try clocking the speed back to 1333mhz with the core unlocked

as i believe the board was only designed to occ with fx cpus in mind in terms of the memory channels
