CAS 2 or CAS 3

[De Joker]

I recently bought a 64 MB generic sdram memory module. The sticker on the memory reads "pc100-222-620" , which is CAS 2 or CL2 as i recently came to understand.

When i use Sandra it reports the memory as "Micron TM4SN64EPH-10 64 MB 8X(8M X 8) SDRAM CL3 PC125-333-622". My question is, which one is correct?.

[daveleau]

Those Sandra numbers reflect PC66 at CL3. I have not really played with Sanddra in this way but would suggest that you get DIMMID to check it out. That is the program I usually use to check RAM.
Good lcuk

Hey Daveleau thanks, i did try dimm id but i tells me manufacturer unknown, pc100 but nothing about CAS 2 or CAS 3.

You need to change your BIOS settings to reflect that you now have CAS-2 RAM.

your ram is cas 2!!!!

the number 222 indicates it is cas 2!!!

If it was cas 3, it would be 322 or 223, one of those!!!

CL2 it is. That's at 100MHz. You may need a BIOS setting of CL3 at higher FSB settings.

wtp ~ Sorry, the gang on Family Feud would not give you a "good answer!" for that. I suggest you study the link I offered above.

~edit~

... good answer! http://sysopt.earthweb.com/forum/wink.gif

Speaking of CAS latency, etc, I've got a question I wonder if anyone can answer. My motherboard (Asus P5A) has three memory timing settings: CAS Latency, RAS to CAS delay, and RAS precharge time. I notice that when I change the present settings to 125MHz, or 143MHz, these settings change accordingly. (3, 3, and 3 at 125MHz, and 2, 2, and 2 at 143MHz) The question is - how do I change these settings to get other timings, such as maybe 133MHz?

[Roy]

jeff7 ~ are you sure about those combinations? I would not expect an automatic setting of CL=2 for 143MHz.

All things considered, these settings don't make much difference in the real world ~ except that a too-short timing will stop an overclocked system. Oh, you might gain a point or two in a benchmark test, but a stable OC system is worth a lot more.

[Jeff7]

Yes, those are the settings listed when I change it to 143MHz. The gains were rather good too. Changing the memory settings to 143MHz from the default setting boosted memory speed considerably: SiSoft Sandra 2000 reported that the memory transfer speed went from around 164MB/sec to 190MB/sec. And it's still stable. I used a memory stress testing utility to look for errors; it passed all tests.
