MA770t-UD3 with 4th DIMM not posting

[ahjmcn]

Hi all,
I recently tried putting in an additional 2 Ram modules on top of the 2 that were already present, with 3 in it runs fine, but with the 4th in it doesn't get past post. Each stick works individually and any combination of 3 work. All 4 ram modules are the same model (Patriot DDR3 1333mhz 2gb). I've tried reseting the CMOS, updating the BIOS, upping the DRAM voltage and cleaning out dust, no luck. Any suggestions?

PC Specs:
AMD Phenom II x3 710
MA770T-UD3
Win8 64bit

Thanks for any help,

Aaron

any 3 in any 3 slots work or last dim slot refuses to work?

if the slot is broken, you wouldn't be able to install that last slot (for example 1,2,4 wouldn't post either) if it's a problem with using 4 when any last fourth is added it could mean something else is broken on the cpu or motherboard or psu.
