igor’sLAB continues to upgrade: On the hunt for (false) elements and measuring the impossible – Keyence VHX7000 and EA-300 in daily use | Issue 1

You can invest a lot of things for and in something. Time, energy and, of course, a lot of money.

I didn’t really want to believe it at first, but after receiving feedback in the double digits, I combined what was pleasant for the customer with what was interesting for me. I analyze and repair the card at my risk, so that the buyer gets a working card back in any case and I am at least smarter in the end. The 30 Kelvin delta between GPU [...]


Thermal Putty instead of expensive thermal pads with different thicknesses and an interesting thermal paste from the Far East

With the Gainward RTX 1660 Super (Susi), I am once again rescuing a graphics card that I had already tested extensively almost four years ago and that has also been in almost daily use since then. This ranges as a career ladder from the office to the recording PC (OBS) and the gaming use in the PC of my youngest son. And at some point the card got [...]
