I just bought this RAM and Installed it combining with the other 2GB RAM i have http://www.flipkart.com/transcend-pc2-5300-ddr3-2-gb-pc-ram-jm1333klu-2g/p/itmd2ryp5fyuyghg?pid=RAMD2RYPY58CUHPG&otracker=from-search&srno=t_1&q=transcend+jm1333klu-2g&ref=f1dceb17-8ee9-40df-a20c-7477e943e4f7 but after installing the computer isn't booting up.The Cpu fan starts running and stops and it repeats.
I tried interchanging RAMs and also reseated cmos.
I also tried placing that 4Gb single RAM.But no luck.
The computer boots up when i place the 2GB ram which came with the computer
I got frustrated restarting and replacing the slots again and again.
What might be the problem?
Please help me.
My motherboard:Gigabyte ga-g41mt-s2p rev 1.4

For your motherboard, the only 4GB DIMM supported (as listed by Gigabyte) is the 4GB Samsung M378B5273BH1-CF8.

Having said that, there is really no reason that the 4GB DIMM you purchased shouldn't work. I would consider returning the 4GB dimm to the retailer as DOA (dead on arrival).

This RAM is already a replaced one.I replaced it because i thought it is dead on arrival.

Any time you mix sticks it can be problematic, or not a good idea to do so...can try raising DRAM voltage + 0.05 and about the same on the MC (memory controller voltage and they might play together)
