TSOP RAM Tester

[More]

Hi Guys,
Longtime reader first time poster... Firstly I'd like to thank the forum for the help over the years and apologise if this question might have been asked in the past.
I'm trying to build a jig to test individual TSOP RAM devices. My plan is use a working RAM DIMM that has the same RAM fitted that I want to test, remove one of the devices and solder a 66 pin test socket via some short connections to where the device once was. I'd then fit the DIMM into a working PC, fit a suspect device into the flying socket and run some basic tests.

My question is do you think I'll run into issues by adding a tiny bit of impedance into the DIMMS circuit caused by the short wires connected to the test socket and if so would there be any way to get around that issue?

Also if anyone knows of any other solutions I'm all ears.

Thanks for any help
