using two different company RAMs

Guys i have two slots for inserting RAM in which one of them is having a 1GB RAM,i don't know its company name, something SRM and elpidia is written on them and now iam thinking about buying another 2GB RAM of trancend or kingston.so do i face any problem in using two different companies RAM? my friend told me that if i use same company RAM it would be better,if i use different companies sometimes it will show 1GB and sometime 2GB i won't get the performance of 3GB.
do i see any boost in performance when i use 64 bit OS(Win 7) than 32 bit for 3GB RAM?

Buy a Kingston 2GB RAM. Both the RAMs will work fine and show up as 3GB.

You won't see much performance increase between 64bit and 32bit OS with only 3GB of RAM. :)

sometimes 1Gb & sometimes 2Gb? NO. it'll either show 3Gb or PC mayn't boot. means the ram isn't compatible with the old ram.

guys what about kingston hyperX Blu is there any performance difference in normal 2GB and hyperX blu 2GB?

^^ hmmmm, performance ram it maybe & won't bring any added performance. at least not with a dual core at stock speed. also it bound cost lot more.

just adding fast ram won't increase system performance. the proccy must be enough fast to utilize the ram well. your proccy isn't fast, so 1066Mhz or 800Mhz, both will perform in same way. if you want a better answer i can go deep but will become complicated.

so best bet is to add 2Gb more. if the 1Gb isn't compatible, remove it.

Please use CPU-Z or something like Everest.
Note down the memory timings on the existing stick.
Get a 2GB stick from the market with similar speed, timings.
The regular Kingston/Transcend RAM will have more chances of being similar in specs to the one you have than any performance RAM and hence a better chance of running stable along with the older stick.

I have doubt.
Processor - xyz GHz
RAM - abc MHz
By that logic, processor will usually wait for the RAM to feed it data?

If someone uses DDR2 1066 CL5 and DDR2 800 CL5 kits on a stock Core2Duo rig, will there be any any performance difference between the 2?

Swimming, eh??
My apologies for not starting a different thread as my question is somewhat related to op's query. And of course i am an lazy as$.
.
Anyway, i just wanted to ask that what are various...eh..'topics' one needs to check and understand while upgrading ram?
.
You see I am thinking to buy another stick of 2Gb DDR3 1333mhz kingston RAM when came to know that one is available for 1550 rs here at my town. I already have same 2Gb DDR3 1333mhz kingston RAM (blah blah) stuck in my pc but I am confused cause of annoying words like 'Timings' and 'FSB'.
.
So any help?? And How am I supposed to check if both the rams have exactly same Timings
.
.
Also, being hairy and noob, i dont understand wether I can put 64 bit operating system instead of 32 bit in my pc.
I have phenom II 955 BE cpu, if it matters.
.
And what is the major difference between 32 & 64bit os apart from RAM usage.

i think you can check your processor supports 64bit or not in bios details page bcoz mine shows.any how here is details about your processor
*www.cpu-world.com/CPUs/K10/AMD-Phenom II X4 955 - HDX955FBK4DGI.html

in my case the 2GB + 1GB RAM works, but as said its better to add a 2GB stick and remove the 1GB stick.

And for 2cores processor in mostly 2GB RAM is enough running on 800MHz.

I think it would make a difference, but not something visible to the naked eye. The OPs processor should support a front side bus of 1066Mhz, so adding that extra RAM will help. Plus if he uses Win7 OS, which is highly optimized for RAM usage he should see a snappy (more) system. There would be less thrashing and page file usage too, which would keep the system quicker.

Please update your signature, and/or mention the full system specifications when you ask queries. Else we need to assume stuff. Regarding your questions while purchasing RAM:

1. Make sure the processor/motherboard support the RAM at that speed. Now there is a slight difference here. Not all boards support high speed RAM out-of-the-box. The website might mention 1333Mhz (example here) RAM speed support for the board, but you would need to make FSB or BCKL, timing, vDRAM voltage changes to get it stable at 1333Mhz speed. This is OC.

2. Try to keep multiple RAM modules of same speed, density and make. Use multiples of 2x for dual channel and 3x for tri-channel (provided board supports).

3. To check RAM information either check the SPD data in the BIOS, or pull up CPU-Z and check. Usually the model number is clearly printed on the RAM side. This can be directly inputted to Google.com

4. Yes you can use 64BIT OS on your system.

5. Here is a good comparison of 64BIT vs. 32BIT. It can be safely extrapolated for Win7.

I would suggest 4GB if you can afford it. Though you would need a 64BIT OS.

guys by seeing this pic of cpu-z can you please tell me which 2GB RAM should i buy?
here is details about my motherboard-
ASRock > Products > G31M-VS2

@sukesh1090: u can use two rams of different companies..but check for the latency & frequency timings ...shud match...even though frequency cud be different...
for e.g: u can use a 400Mhz ram with 333Mhz..but the higher will set itself to lower frequency.....

^^then whats the point of checking latency?'cause anyways the RAM modules are gonna work..
And lets say the latencies are different..then what will happen to the system?I mean will it shutdown improperly or crash or something else..
