Would like to have this done, unfortunately I do not have the skills neccessary to do it. Thanks

Mickey223: I am still doing the memory upgrades. It has been a while since anyone has requested the service. The current problem is finding memory to install. Your ePods will need either "fast" (70ns) or "slow" memory. The "slow" memory is relatively easy to obtain. The chips can be removed from the memory module that comes stock in the i-Opener. I'm guessing that there are hundreds of these modules sitting around unused by members of this board. I may still have some of these modules around (I'd have to check). The "fast" memory is hard to find. I was removing chips from a Crucial CT4M64S4D7E memory module to get the necessary parts. However, Crucial stopped making that module a long time ago. There may be other modules that have suitable chips.

If you can find the memory, I can do the surface mount work. Let me know if you want to pursue this. I will be happy to give you advice on finding the memory, but you will have to do the legwork.

Look at the ePods32 website for information on how to determine what memory that you need.

Unfortunately I do have the 1.1 board with the crucial memory. I have been looking for the module for a while, and have yet to find it. That's why I was hoping someone was still doing the upgrades. If I can find one. I'll let you know. Thanks

Glitch,

I do not have the exat ram, but do have something similar. The datasheet is at

http://www.valueram.com/datasheets/KVR133X64C3_128.pdf

and the IC's are

IBM N364804CT3C 75A 06K3907

Do you think this would work?

Thanks

Mickey

Mickey: I'm doubt that the memory from that module will work. I wasn't able to find any specs for the chips to know for sure. The speed of the chips is probably a bit too slow (75 vs 70) and the address/data lines are more than likely different. The modules that stand the best chances for a match are 32MB PC133 CL2 SDRAM with 4 chips per module.

I've recently won a 32MB memory module on eBay that looks promising. However, I'm not sure if the chips on this module will work. I'll know more once it arrives and I can experiment with it.

There is also the option of finding chips that have the same data bits but extra address lines (i.e. higher capacity chips). These would need to have the same pinouts as the "correct" chips. The extra address lines would not be used. You would be only using 1/2 or 1/4 of the memory on the chip. I looked into this a long time ago and deemed that it would be feasible. However, I did not pursue it because the "correct" chips were readily available back then.

Sounds good, I'm still checking on the memory I do I have, and will see what I can find. Thanks

I wanted to check with you guys if you thought some chips might work to make my ePod an ePod32.

My ePod is a vers. 1.1 with 70ns chips. The 32 meg module I have is a MOSEL VITELIC 32 meg SODIMM.

The number on the chips are

9945PR
V54C365164VCT8PC

The main SODIMM sticker says

V43644Y04VCTG-10PC
PC100U-222-612-A


Thanks

vetteguy: It sounds like your memory module is one from an i-Opener. It is PC100 memory with 80ns chips. This memory works well with ePods that have 100ns memory, but usually doesn't work with ePods with 70ns memory. You need to find a 32MB, four chip, PC133, CL2 module to get the correct chips for your ePods. Needless to say, a module with these specs is very hard to find. When 32MB modules were plentiful, they were slower memory (PC66 and some PC100). Once the memory got faster (PC133+), the memory modules were usually larger (128MB and larger).

I've recently purchased a DIMM that may have chips that will work on the 70ns ePods. The chip numbers are Hyundai GM72V661641ET7J. I have not been able to find specs for these chips yet to know for sure.
