PC 100 / 133 MB memory. How can i tell what is what?

[wuchuck]

I recently got a 133 Mhz capable motherboard. The problem is that my old PC100 memory got mixed in with the 133 memory. How can I tell which stick is what? Is there a way in windows or bios to tell what speed my memory is running at? If I leave both sticks of memory in my computer, will they be limited by my slower memory? Thanks for any help you can give me,
-Tom

Hi!

Sisoft Sandra usualy reads the memory setting from the chip itself. I'm sure there are meny other utilities...

Other way is to look at the chip and you will see a lot of numbers there but at the end of it will be the speed of memory.

Some marking:

xxxxxxx-10 (100 Mhz memory)
xxxxxxx-08 (133 Mhz but slow timing)
xxxxxxx-07 (133 Mhz but normal timing)
xxxxxxx-06 (I never seen it so I don't know, itt could be the 150 Mhz or a
very fast 133 Mhz (Cas-2))

The last number is the nanoseconds number representing the time needed for memory to
put data on the bus after the request arived from CPU.

Hope it helps,
Cheers,

Thanks I'll give that a try...by the way, any clue where I might find this software? Is it worth getting?

Here's the link to SiSoft Sandra. It's got lots of useful info and lots of people use it's benchmarks and burn-in wizard.

Another program you should try is ctSPD. The majority of the site's in German, but the program is in English. It'll give you tons of information about the current memory sticks you have installed. Here's the direct download link.

Edit: Oops, fixed link.

Hi!

Correct link is: "ftp://ftp.heise.de/pub/ct/ctsi/ctspd092.zip"

Cheers,

gee...sorry to bother you guys again but I tried the link and it had problems decompressing. When I tried to run the exe file it gave me an error about getting the correct program to match my window's platform. I take it the link wasn't for a win98 OR ? Any other links? I can't navigate the german page =P.

Cookie: according to official specs, 10nS is 66, 8 is 100, 7.5 is 133, 6 and faster is HSDRAM (High Speed SDRAM). however 10nS can be generally used at 100, and 8 can be used at 133.

Hi!

Well you are right, 10ns is 66Mhz indeed (thats what i wanted to write but time is always against me... ).
I had all kind of problems from trying to run 10ns SDRAM at 100 Mhz, so I would not recomend this.

Thanks for correcting me.

Cheers,
