Intel 13th Gen Raptor Lake Binning – smaller, but still neat! | Part 2: i7-13700K/KF and i5-13600K/KF

In keeping with today’s date, we continue with our Intel Raptor Lake silicon lottery data today, namely with the overclockable i7 and i5 SKUs. So whether your 13th Gen chip is a winner or a loser, you can find out today, among other things. At this point, I would like to refer to the previous article on the i9 chips, since the procedure for [...]


SpyderX Elite vs. ColorChecker Display Plus – Colorimeter comparison

Today for the weekend we have some light food. A few weeks ago, I switched my testing software – for my monitor tests – from DisplayCal to Portrait Displays Calman Ultimate. I had written a dedicated article on this and afterwards there was quite a tense disagreement in the forum (to put it mildly). The topic was not the Calman [...]


Repair of a crumbled Beyerdynamic Custom One Pro and lab measurement of a completely messed up mechanical sounding

You probably remember my Beyerdynamic Custom One Pro headset, which simply destroyed itself in storage completely without use and which I had as article published last week. Being a sustainable person, I fixed the part today at my expense after having to wait a few days for the parts. The test will have to prove whether it was worth it – on [...]


12VHPWR adapter for NVIDIA’s GeForce RTX 4090 – Two manufacturers, contact problems, bending radii and the human factor

The 12VHPWR adapter for the GeForce RTX 4090 is unfortunately already a kind of running gag and so the topic is meanwhile beaten by all more or less well-informed media. A little unemotional reappraisal would certainly not be a bad idea to calm heated tempers and put the whole thing back on its feet. Therefore, today’s article is not only an [...]


The daily scam on eBay: When the cheap Eastern Digital Green SSD of a top seller suddenly halves | Test purchase and warning

Let’s be honest: is there currently an SSD with 2 TB of storage available for under 50 Euros? If it were up to certain eBay “top sellers,” it probably would. This contradicts the search results in reputable stores, but maybe the little technology miracle is taking place just outside of the usual big online shops. For example, if [...]


Cause simpler than thought? NVIDIA GeForce RTX 4090, the scorched 12VHPWR connector and how to plug it in | Blind Test

Sometimes you also have to listen to your children and do a blind test once. Apart from the fact that there are obviously three or four adapter types with different solder pads and cables, the problem of the hot contact surfaces of the outer connectors must have a simpler reason. I already wrote on the subject of bending that the rigid pins in the [...]

This is how the 12VHPWR is done correctly: Crimping instead of soldering and how to supply the GeForce RTX 4090 with power properly

First there were bent cables, then annoyed buyers of the at least 2000 euro expensive NVIDIA GeForce RTX 4090, no matter which model or manufacturer. The manufacturer of the 4-pin adapter from 12VHPWR to 4x 8-pin for older power supplies was also careless. And, of course, we learned something once again in the course of our investigations.
