Hi All,

Just received my unit and put together. Super please with build quality.

Did my first test on a 4464 DRAM chip. Takes a while but the chip passed.

A little bit later ran the test on a second 4464 chip. Does a column count to 255 and then goes to the next section of the test and the DRAM fails. I tried this with a number of chip and get the same issue. I tried the first chip that did pass and now it's failing.

Using the VU GUI on my Mac, I can't actually see the unit connected although it did show up previously.

Any suggestions on how to resolve this issue?

Thanks
