128megs on a CSA Derringer 030

I will definitely try it. Now i am using 64MB SIMM which D3 detects as 16MB.
The system is stable with it.

Do you think I will get 64MB with this hack?

The SIMM is single sided with 8 chips on it. The chips are MT 4LC16M4H9-5D.

I have desoldered U17. Pin 12 appears to have no trace. Can I cut the traces on pin 13 and 14, so I don't have to lift them? Like on the image that I have attached.

I just finished the mod. It's working!

Added mem with Addmem. Got 64MB with my 64MB simm.

Avail shows largest block 16MB. I think that's normal.

Thanx Metalguy66!

Avail shows largest block 16MB. I think that's normal.

Sysinfo shows largest block 65MB. I tested it. Created 28MB lha archive in ram:. Without errors. Tested the archive. Without errors. Nice.

I got my 128meg SIMM from Mech of a4000t.com

What is he type of the chips on your 128MB SIMM? Could you make a photo?

Thanx

Hmm, your memory chips are for 3.3V like mine too. Do you think
they can manage 5V too? I did not have problems with mine yet, but there
is duscussion on other forums that 5V can destroy them.
