I have a 4 year old computer with 256 MB SD RAM 533Mhz (i think). Can i buy another 256 / 512 MB RAM and up my RAM to 512 / 768 MB ?
How much will it cost and where should i head to ?

That means it's a DDR333 module, also called PC2700. The clock frequency is 166.7 MHz, but since it's a DDR (double data rate) memory, it is effectively working as if it's running at 333 MHz. What may be confusing to some is that DDR RAM is a special type of SDRAM and may be tagged as DDR SDRAM.
I recently bought some 512MB DDR400 (200/400MHz) sticks @ 800/-.
In most cases, no. If you install two or more RAM sticks of different speeds, they will all run at the speed of the slowest one. However, there are occasional cases where they can cause stability issues, especially when they are run in dual-channel mode. Personally, I have never had any problem using RAMs of different speeds in single-channel mode.
Where ? Which brand ? Whats the price of 1GB ?
and 512MB still 800 rupees ?
oh its dynet ? thats why its cheap. low quality...
It's up to you if you want to use them or not. No one's twisting your arm.
Why not ? I'm using two of them in one of my computers, an A64 3000+, and they passed testing with memtest86-3.4 for 3 hours with flying colours.

Sorry I coudn't reply due to a power cut
Computer Warehouse in Bangalore lists 256MB SDRAM at Rs.470 and 512MB at Rs.630, excluding 4% VAT. They don't mention the brand or the speed, so you'll have to ask them.
I don't like dedicated threads, so I'll answer here. Quoting from that thread :
I don't know the cheapest source in Bangalore, but Computer Warehouse on M.G.Road has various brands listed at around 1K for 512MB and a bit less than 2K for 1GB. I occasionally had a problem with Zion RAMs in the past, so I can't recommend them.
You will definitely see improvement in performance even if you add just 256MB to your existing 256MB. Your computer will boot up more quickly, programs will load faster, games will run more smoothly and multitasking will be easier. You can also allocate more shared memory to graphics without crippling the rest of system performance.
Personally, I've never had a problem mixing RAMs from different sources except when run in dual-channel mode.
Pricewise, it is almost always cheaper to use a single stick. But using two matched modules in dual-channel mode has a slight speed advantage. However, that advantage is usually only a few percent and not really noticeable except in benchmarks. So a single 1GB stick is probably better if you're on a tight budget.
That doesn't make much sense. It would if you'd said "DDR2 is cheaper than DDR because.........."
There's no DDR300 AFAIK but I'll take that as a typo
