Okay, I am completely lost and I feel like a total idiot. I'm dumb with this stuff so please have mercy. I recently took out the SD-RAM from my PC because I plan on puttting in more, or different SD-RAM. I have the RAM from my PC here which reads:

Infineon, HYS64V16300-7.5-C2, 16MX64, SDRAM, C3E12318, PC133-333-520, Assembled in Malaysia, 128MB, Sync, CL3

Then just recently I tried to insert SD-RAM along with the above one but ended up getting garbled bleep on my screen at startup. It was one from these next two cards that I pulled out of an old IBM computer:

This was the one I tried to insert:
Infineon, HYS64V8300GU-8-B, 8MX64, SDRAM, B2W95110196, PC100-222-620, Assembled in USA, 64MB, SYNC, 100MHz, CL2
TOSHIBA, THMY6480H1EG-80, 8MX64, 105777/0021UKC, PC100-222-620, ASSY IN USA

Then I have two more from an old Dell computer which I haven't tried yet because I don't know what the hell I'm doing:

325391, PRD, 05E4, PC100, S-DR, PC-64MCT
GMM26416233CNT, G-7J, 8511G, PC100-322-620
The above two contain 192MB RAM total.

So can someone explain to me what I can do to get the highest combination of two SD-RAM cards for the most RAM with having compatibility?

Hi KPhoenix, and welcome to BleepingComputer,

What is the make and the model of the computer?

The RAM module that was already in your computer is PC-133, the other modules are PC-100. If you get one of the other modules to work with the PC-133, the PC-133 module will only run as fast as the slower PC-100.

The first two PC-100 modules are only 64MB, the third I couldn't find any reference to. The third PC-100 module (GMM26416233CNT, G-7J, 8511G, PC100-322-620) is 128MB, I would add it.

You might try inserting the modules one at a time to see if the computer will boot with any single one of them.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

your system may only support PC133, and with it being that old, may be getting very finnicky about what type of PC133 you are trying to install.

would need the exact make and model of motherboard to give you better answers.
