Need help identifying SDRAM modules

[blue_shark]

Hi all!

I've got two sticks of Samsung PC133R ECC SDRAM lying around that I want to sell, but cannot tell how much RAM each of the sticks has.

Both sticks have 9 chips per side (ECC memory) and identical part numbers (Part No. M390S2858DT1-C7A, DRAM Part No. K4S560432D-TC75, DRAM Vendor Samsung). There is also 'Korea 0222 PC133R-333-542-B2' written on a sticker.
I don't have any compatible old mobo to test the modules, so is there any other way to determine the amount of RAM per module?

I've tried googling it by part number and DRAM part number but results are ranging from 128MB to 1GB per module.

Any help would be appreciated.
