How can you tell if a stick of RAM is CAS2 or CAS3?

[Hankysmoo]

I am looking at a stick of Infineon ram right now with markings

Infineon
hyb39s64800bt-7.5
Germany B

anyone know if this is CAS2 or CAS3?
thx

 

[CraigRT]

well this is how i find out
i put it in the board and if it runs CAS2 perfectly fine, it's CAS2
right now my PC100 generic RAM is running 124 FSB at CAS2 !!!

I believe your PC133 is rated at cas3, but it will do cas2 @ 133 no problem.

I currently have PC100 Infineon running 135MHz FSB @ cas2

Those codes won't do it, I don't think, unless you can trace them at Infineon's site.

If you want to see how your installed RAM is officially rated get SiSoft [Sandra] Prof. 2000. You can download a shareware version and it will tell you more about your PC than you ever imagined you were ignorant of. See:

Of course the 7.5 notation means its 133 MHz RAM (1000/7.5 = 133)

thx for the info guys...I downloaded the SiSoft Sandra Pro like you recommended ulysses but still don't see the option of telling if the Ram is CAS2 or CAS3 rated...I just see memory benchmarks...

It is under the "mainboard information" module I believe.

some ram say
333
or 322
or 222

that tells u if cas 3 or cas 2

but u can always try spd in bios
it will pci kup if it is cas 3 or cas 2

last resort use sis soft

 

[xtreme2k]

322 = cas3
222 = cas2

the first digit = cas lantency
