Can someone give me specs on this RAM?

Two sticks...

1. Samsung...markings:

Samsung
Korea 9905
PC100-322-620
KMM36651623CT-GL

marking on the RAMchips:

SEC KOREA 904
KM4858030CT-GL

2. PNY...markings:

32MB SYN DIMM 100
WH 2336559
415ES

markings on RAMchips:

9945PR
V54C365164VCT7

Not the highest quality of RAM...basically all I want to know is CAS ratings. Most of it's obvious from the chips, pc100, etc...but I don't see anything that would indicate CAS latency.

Anyone?

Samsung's site did not list the KM4858030CT-GL. However, based on the naming convention, it is be PC100 CAS3 memory
Are you sure you don't mean KM48S8030CT-GL? KM4858030CT doesn't seem to follow the Samsung naming convention. I think you must have misread S for 5. The KM48S8030CT is a 8Mx8 64Mb PC100 memory chip that's rated at CAS latency 3. More information can be found at http://www.usa.samsungsemi.com/admin/production/globalsearch.asp?key=KM48S8030CT

The PNY module seems to be using Mosel Vitelic SDRAM chips if I'm not wrong. The chip should have a logo that consists of a 3/4 circle with 9 square dots at the top left part of the circle right? If so, according to Mosel Vitelic's website, it is a 4Mx16 64Mb memory chip that can be rated at 125/133/143MHz. It should be a PC100 module. More information can be found at
http://www.moselvitelic.com/frames/frame_Dynamic.html. I tried clicking on the V54C365164VC link but it gave me an error on both Netscape4 and IE5. I think the PDF file might be corrupted, as both Acrobat and Ghostview gave me errors with it. The other links on that page is ok though. I checked out the V54C365404VC, which I believe is the same SDRAM chip, but organized in 4 banks of 4Mx4 structure. The V54C365404VC-7 is rated at 143MHz or 7ns cycle time, which means your V54C365164VCT7 should be rated at the same speed too. Its CAS latency is programmable. If I understand the datasheet correctly, you should be able to run it at 143MHz at CAS latency 3, or 100MHz at CAS latency 2. Perhaps you can check it out yourself.
