NVIDIA’s and AMD’s demands on the PCI SIG for the new 600 Watt VGA cards – limits, allowed overruns and transients | Exclusive

Is the 600 watts really the upper end or where are the tolerance ranges for exceeding the standards for a short bursts? And why does the GeForce RTX 3090 Ti suddenly show a completely different behavior under full load? I will answer exactly these questions today, because the review of the GeForce RTX 3090 Ti has (probably not only) made me [...]


Gigabyte GeForce RTX 3080 GAMING OC WATERFORCE WB – When aluminum destroys the cooling circuit | Investigativ

Due to a given occasion, I now even have to add a third part to my water cooling investigations. It will unfortunately show what happens when you combine (without knowing it) an aluminum cooler with copper components and I will specifically question why the result turns out so extreme, as in this case. Of course, you also have to differentiate the [...]


Missing flux compensator: Flux residues in cheap radiators – why so many AiO water cooling systems really die | Investigative

I did not make it easy for myself, but worked on this topic for almost half a year. In the first article last year I had already written about clogged radiators and tubes, defective pumps and the theory behind the coolants on their additives. After a very complex analysis with the scanning electron microscope (SEM) and with the help of energy [...]


Depth examination of thermal paste (ArcticMX-4): Searching for snake oil with scanning electron microscope and X-ray spectroscopy. What’s inside?

To describe it in detail, otherwise the headline would have been too long: Today, we will use the field emission scanning electron microscope (FE-SEM) and energy dispersive X-ray spectroscopy (EDX) to analyze in more detail what is really inside one of the most popular (and also cheaper) thermal pastes in the form of the Arctic MX-4. The [...]


DDR5 Deep Dive – Exclusive interview with Kingston about the new memory standard and many examples from practice

The basic changes to the new DDR5 memory standard have already been discussed around the launch of the Intel Alder Lake CPUs, even if sometimes not completely correct. So today we’re going to revisit the topic and delve deeper into the matter together with Kingston, who were kind enough to provide us with a written interview. It’s no [...]


Insights into ATX v3.0, ATX12VO v2.0 and PCIe 5.0 – When resource waste becomes the new standard | Investigative

The race for ever faster CPUs and above all GPUs is now producing such blossoms that even existing standards have to be softened or modified for the new energy waste offensive that soon every end consumer will have to save up for a portable nuclear power plant if they don’t want to be in debt with the energy supplier well into old age. To [...]


Intel Alder Lake Test: When motherboard settings affect the power consumption and temperature of the CPU | Practice

Are you still amazed about the so different power consumption values at the different launch reviews of Intel’s Alder Lake? In the meantime I have the data of a second motherboard model and I could hardly find any deviations to my measurements. The second board is an MSI MAG Z690 Carbon Wifi, which positions itself one price and performance [...]


USB ports and latency measurements – myths and reality | Practice

After the last article about system latency (NVIDIA Reflex & Boost vs. Radeon Boost and ZERO vs. AMD Anti-Lag), we should urgently discuss a few things about testing. So today we’re going to take a look at NVIDIA LDAT in terms of the USB ports it uses. For this I tested two different possibilities regarding the use of LDAT. The AMD [...]
