Is EDO memory better than SDRAM in PC66 boards?

[GBertolet]

I have a 1997 Gateway P55C-200 desktop. As a project I am trying to restore it to some sense of usability for simple internet browsing. I do have a new main computer, so this one is a secondary one.. The computer is originally 200mhz, 32 meg ram, and 4 GB hard drive. I have been able to speed up the processor from 200 to 233 mhz. The computer takes a wierd type of memory. The manual says I must use PC66 sdram 4 clock, CL2 memory boards, or EDO memory, with a total board limit of 256 meg of ram. I found, and installed two PC66 128 meg sdram 4 clock CL3 boards. I was told that the CL3 could be substituted for the CL2.

After doing this, the computer did not seem to work any faster. The computer sees the 256 meg of memory, but does not work much better than the stock 32 meg. I don't know if the original memory was EDO or not, as there is no info printed on the board. I have tried IE6, AOL 9.0VR, Opera 12.02, and Firefox 3.6.28 and 10.07. All with similar results. The pages connect quickly, but take several minutes to populate.

I am wondering if the EDO boards are better for this application. Unfortunately 64 meg is the largest EDO board out there, limiting me to 128 meg total instead of the current 256 meg. Are there any opinions on this issue.

Hi,

EDO memory is an older form of Asynchronous DRAM that was superseded by JEDEC Synchronous DRAM (SDRAM) and eventually JEDEC DDR SDRAM.

If you have 256MiB of SDRAM, you're already at the board's capacity and performance can only be squeezed elsewhere.

EDIT: As a side note, you should not be using that computer on the internet. Those microprocessors do not support data execution prevention or many other modern security techniques.
