Hi,
I am looking for a freeware utility to get the complete information about the RAM chip that is installed in my PC. The thing that I am mostly interested is the number of pins (whether it is 168 or 200 or 240). I tried several softwares like CPU-Z, PC Wizard, Everest Home Edition, Winaudit etc, but none of them seems to give how many pins my memory chip has got.
Can some one help me? I can easily get this info by opening my PC, but I just don't wanna do it.
Thanks,
Balaji.

Try SIW.exe. That utility will yeild a wealth of information on your hardware and software. Get the standalone version at the link below.

Hi,
Thanks for your response. Tried it and I do agree that it gives wealth of information about the hardware in my system, but still doesn't show me the number of pins of my RAM chip.
Thanks,
Balaji.

"The thing that I am mostly interested is the number of pins (whether it is 168 or 200 or 240)"
I don't believe software will tell you that. SDR-SDRAM (PC66, PC100, PC133) has 168-pins. DDR-SDRAM (PC2100, PC2700, PC3200) has 184-pins. DDR2-SDRAM (PC2-4200, PC2-5300, PC2-6400) has 240-pins. DDR3-SDRAM also has 240-pins but it's keyed differently to prevent it from being used in DDR2 slots.

"I can easily get this info by opening my PC, but I just don't wanna do it". Ain't that easy to count. I figured if you knew the type of RAM you would be set. After all, that is how you purchase RAM.
Were you trying to find out what type of RAM is in your hand?

Thanks for the reply. Ok. I will re-phrase my questions. My PC has PC2-4300 RAM chip and I don't know how many pins it has.
See the links below.
240 pin PC2-4300 RAM
http://www.buy.com/prod/edge-tech-5...200 pin PC2-4300 RAM
http://www.buy.com/prod/transcend-5...That is why I am confused. My PC has 4 slots and 2 slots have 512MB RAM in it. I am trying to upgrade the RAM, but the number of pins is what is confusing me as to which one to get.
Hope you understand my problem now.
Thanks,
Balaji.

OK, I understand your confusion now. The 200 pin RAM is Laptop RAM. Laptops use smaller RAM modules because everything in a laptop is compact. The SoDIMM at the end of the string tells you it is laptop RAM.
512MB - 533MHz DDR2-533/PC2-4300 - Non-ECC - DDR2 SDRAM - 200-pin SoDIMM
When trying to buy compatible RAM it is best to use a site that can tell you exactly what RAM will work. There are other factors besides getting the correct type.
Go to crucial.com and use their online scan or memory configurator. You don't necessarily need to buy from crucial and they are not the only site that provides that data.
OEM computers like HP, Dell, Gateway can be fussy about what RAM they will use. Best to get something compatible.

Thanks for the reply. That really helps. I downloaded the crucial scanner and it really gives good information.
Now, one more question. I have 2 empty slots in my PC and I am thinking to install 2 1GB 240 pin chips to get a total RAM of 3GB. Mixing this 2 512MB with 2 1GB will work with out any issues?
Thanks,
Balaji.

If it's a desktop machine (which it probably is), the RAM has 240-pins. If it's a laptop/notebook, the RAM has 200-pins...notice that it's called "SoDIMM" for "small outline dual in-line memory module". The pictures should have been a clue. Even if you didn't wanna remove the RAM from your PC, just looking inside the case should have tipped you off as to which.

As long as the RAM you get is compatible, there should be no problem mixing them.

If you went to Crucial.com and ran the scanner, all the information you need to select compatible Ram Modules and how to best configure the modules in the Motherboard slots is spelled out on-screen.
Without knowing the Model # of your Pavillion or the Motherboard you have installed, no one can definitively answer your questions. Crucial.com's scanner will.
Run the scanner again and read all the Information. Any special configuration of the 1GB and 512mb modules will be spelled out including, in Graphic form, identifying Slots by Number,0-1-2-3, and drawings of Slots indicating proper configuration of mixed size Ram Modules.
There is nothing to learn from someone who already agrees with you.

Hi,
Though my PC has the PC2-4300 RAM chip, crucial.com is recommending PC2-4200 and PC2-5300 also as the compatible models? Is it okay to mix the models like this?
If I use mix the models like this, will there be any memory leaks or any other problems?
Thanks,
Balaji.

Should be OK. PC4300 and PC4200 are the same thing. Actually is 4266. You can use the faster PC5300 but it will only run as fast as the slower RAM. Buy what is cheaper.
Keep in mind that not all RAM is created equal. Crucial guarantees their RAM to work if you buy the RAM stick/s they recommend.
