Computer Stats?

Is there anyway to find out what kind of RAM I have in my computer with a program? I'm mainly wondering what speed it is, Mhz, or the PC speed or whatever its called, I'm afraid I might of bought the wrong kind of RAM for my computer, lol.

Ok, thanks,

Is there a way to see the speed of my RAM from this? Not the amount of RAM, like 512mb, but the speed of it.

thanks

cpu z

Indeed! It's a nifty tool to have.

is it always accurate on the RAM speed? heh, its saying a speed I don't like, heh, because I might of bought the wrong kind for this computer

I looked on cpu-z and it was saying 166.2 or 166.3 mhz, it kept changing between the two, so maybe thats avaliable speed or something like that? I looked under 3DMark05, and it said 333Mhz, which is a bummer, but oh well heh. What happens if you mix two different speeds? I ordered some 533Mhz, I thought thats what I had, heh.

Okay, memory is tricky because there's about 50.58462 different ways to reference speed.

the 166 mhz you're seeing is before the data rate is doubled. People often double the speed (i.e.: 333 mhz) because most likely the type of ram you have is DDR RAM (double data rate random access memory). Different programs show different speeds as a result.

As far as buying memory, you'll see two different kinds of numbers: PCxxxx and DDRxxx.

PCxxxx is the theoretical throughput, or the DDR MHz multiplied by 8. For example, PC3200 = 3.2 GB/s = DDR400 * 8. Likewise, DDR400 = PC3200 / 8.

DDRxxx is the speed in MHz, this number is always the number after taking into account the double data rate (when people multiply the speed by 2). Example, DDR400 actually runs at 200 MHz, but since it modifies data on both the rising and falling end of the clock signal, it runs at an effective speed of 400 MHz.

I'm guessing you bought some DDR533. Anything over DDR400 is specifically designed for overclockers to give them some headroom, because unless you have an overclocked computer, current day technology only supports a max of DDR400 (200MHz). This isn't a problem though -- DDR533 is only the speed at which the ram is rated for. This means it's tested to run fine at 533MHz. It theoretically can run at slower speeds, and usually will, but is not guaranteed to. if you mix ram speeds, you'll have to settle for the slowest ram speed.

depending on the return policy, if you can try it first to see if it works before returning it, do that.

check your BIOS. Tells you everything. or CPU-Z..
