Hello there,

My Rig:

MOBO: GA - B75M - D3H LGA 1155
RAM: 2 x 4GB DDR3 1333Mhz Kingston (That I already have)
PSU: 520W
My BIOS was updated to a recent Gigabyte American Megatrend Revision F15, Revision 1.1 (successfully).

When I bought 2 more extra RAM sticks which are IDENTICAL to the ones that I am already using.

After successful BIOS update, CPU-Z even corrected my Memory Slot #s in the correct order.
(They usually don't)

When I tried putting 3rd stick or 3rd and 4th stick at the same time to my remaining slots which I am really sure they are the correct slot for the 3rd and 4th.

my pc would start for about 2 ~ 3 seconds and would turn off itself and repeats i don't know for how long.

It doesn't beep at all.

I am thinking if this may be a PSU issue? but Putting extra 2 RAM sticks doesn't really make even a tiny change to the Power Consumption, isn't it?

If anyone could give me some idea or even a solution, it would be much appreciated !!




 
Solution
Mixed sets are often problematic - even the same exact model. Try starting with the original 2 sticks and go into BIOS make sure freq and timings are correct, then set the DRAM voltage up + 0.60 above spec voltage
