Pc wont start after I installed more RAM

[Chrisss8]

I have just purchased 4bg
I had a Kingmax DDR3 4GB 1333 already in STOCK#1 and now I put the exact same RAM into STOCK#2 , my PC starts up but I only see black screen and I dont see my GPU fan working, I checked with only 1 RAM inside and my pc works perfectly with both Rams but only 1 inside at once...Oh and my BIOS is up to date
Any ideas?

I've never heard of Kingmax, so that may be the first concern here. Hardware functionality aside, you should reply with what motherboard youre using specifically,, how many DIMM slots it has, etc. Mobos tend to be particular about which slots you use when employing multiple sticks of RAM. Also, you should make sure the RAM is compatible. Optimally, itd be the exact same model, but different sticks may work if they at least have the same timings.

Gigabyte M68MT-S2P: Current BIOS version: F1 it's old motherboard but still has to support 2 rams i guess.
2 DDR3 slots
To be more specific this is my motherboard http://www.gigabyte.us/products/product-page.aspx?pid=3497#ov but its 1333+ not 1666+

And youre saying it worked with 1 RAM stick installed. Have you tried with both sticks or just the one?

To elaborate, Id like you to verify that both of the sticks, when installed individually, will get the PC to boot.

Try with 1 stick, go to BIOS and raise DRAM voltage to 1.575 then save, exit, shutdown and try adding the second stick

OK so I tried it again, both ram slots and both ram sticks working fine, I changed the voltage then tried with 2 sticks and I only see is black screen.
I'm lost.

Memtest86 done no ERRORS

Hi, I had this same problem as well, I reseated my ram and it worked. Make sure it clicks in. I can't help you with the voltage (no expert) but try reseating, or changing what slot their in.
