i was planning to buy ram i m confused...I can get 8 gb ram 1333 mhz (2x4gb) for Rs.2000 (not a well known brand) and g skill sniper 4gb (1 x 4gb) for rs.1850 1600 mhz which one to choose.I mainly use my pc for gaming and i have both 32 bit ad 64 bit OS.Currently using 32 bit.

Here's a couple choices:
DDR3-1333:
$38 2x4GB DDR3-1333 CAS 9 F3-10600CL9D-8GBNT -> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231422
$65 2x4GB DDR3-1333 CAS 7 F3-10666CL7D-8GBRH -> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231402

DDR3-1600:
$52 2x4GB DDR3-1600 CAS 9 F3-12800CL9D-8GBRL -> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314

CAS Info -> http://en.wikipedia.org/wiki/CAS_latency

Simplified explanation:
You have to look at RAM as a whole Frequency {bandwidth} and CAS {pauses} with transmission. Think of is this way a car can instantly go 100 MPH but the Stops are longer (9 sec) vs 75 MPH but the stops are shorter (7 sec) both with a 100 stops in a mile. Further, the CPU however...
Well 32-bit is limited to 4GB (3.0GB~3.5GB usable), next 8GB, 64-bit required, is perfectly fine for Gaming, next NEVER get individual stick(s) for pseudo sets. DDR3-1333 'can' be purchased individually, but it's nothing I'd do for a Gaming rig.

Note Windows Memory Limits -> http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx

Sure RDIMM, Server ECC, can be added that way -- I have a box of ALL the same RAM in that rare example.

The Frequency depends on the platform, on SB and most any I can think of DDR3-1600 provides faster FPS over DDR3-1333. If you have an AMD then you'll need a 4-core to use much less gain from faster RAM.

Q - What EXACT RAM? ; provide links
Q - What CPU?
Q - What MOBO?

A single DIMM runs in single channel mode which is a little slower. Also note that adding another of the same DIMM later is NOT guaranteed to work and often will not with DDR3. It's always best to buy ONE matched, tested RAM Kit for your specific brand CPU to be sure it will function without issues. No name RAM can be an issue and may not carry a Lifetime Warranty.
 
Again, never get 1x__GB DDR3-1600 individually; DDR3-1600 in a non-set rarely work together as a pseudo set at Rated Frequency and CAS. I have a few hundred posts about this topic so Google it or trust me it's a bad idea.

Since running DDR3-1600 requires a FSB or CPU-NB Frequency OC IMO get the Set of 2x4GB DDR3-1333 the difference is 0~2FPS and there's a lot more upside as a Matched Set.

Keep in mind a Good DDR3-1333 CAS 7 is faster than DDR3-1600 CAS 9. Frequency is only part of the RAM's speed. Ideally, DDR3-1333 CAS 7 or 8 @ 1.50v, or DDR3-1600 CAS 8 or 9 with 1.50v~1.65v. Lower voltage RAM on that AMD won't run.

Are you sure, RE MOBO, maybe you meant MSI 880GM-E41 http://www.msi.com/product/mb/880GM-E41.html#/?div=Detail
Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600*/1800*/2000*/2133* (OC) DRAM, 16GB Max

Think of is this way a car can instantly go 100 MPH but the Stops are longer (9 sec) vs 75 MPH but the stops are shorter (7 sec) both with a 100 stops in a mile. Further, the CPU however says you can run only 85 MPH.

How long does the car take to drive a mile?

That's the same as your CAS 7 vs CAS 9 question with Frequency.

You can buy g skill ripjaws 4gb 2x2gb 1600Mhz and would run in dual channel mode if supported by your mobo.
