As #GamersNexus pointed out: This is #Greedflation!

There is no other explaination re: 42% above #MSRP for #GPU|s that ain't having hands-on customer support for extreme overclocking!

  • Like those were absurd but one could at least justify the price with the added cost of having to basically pre-pay at least 1 hour (if not multiple hours) of labour for a spechalized technician that walks people through on #extreme #overclocking!

Hold onto your pocket protectors, folks! This article promises to make computational lithography faster with #GPUs, as if #overclocking a potato 🥔 with a hairdryer wasn't impressive enough. Spoiler alert: they used lots of big words to remind you how smart they are while forgetting that nobody actually cares. 💤✨

Ich komme gerade aus dem Staunen nicht mehr heraus. Meine neue #AMD #Radeon RX 6800 verbraucht einfach mal 100W weniger Strom, wenn ich die Corespannung um 90mV absenke und die Taktrate auf 2077MHz begrenze (Default 1,025V und 2,3GHz).

In Cyberpunk 2077 macht sich das mit ~8% Leistungsverlust bei 1440p Ultra ohne FSR bemerkbar. Das sind ganze 5 FPS.
Diese 5 FPS kosten 100W Strom 🤯

#Overclocking time! One of my favourite 286es is getting a makeover!

This one has a weird chipset branded "Solutions", but it turns out it's really a bog-standard (but very cool!) C&T NEAT chipset. The board itself seems to be of the brand Cotek, but that's just going by the stickers on the BIOS and KBC. According to #TheRetroWeb however*, the brand is PCT - but no model name is to be found anywhere. The stock configuration of this board seems to be a 25MHz CPU with a 50MHz crystal driving it. So it's already a damned fast 286 - but there's no reason it can't go even faster!

Well, long story a bit shorter: After some extremely clumsy soldering on my part, I was able to replace the main 50MHz crystal with the Any_Clk, a custom, variable clock generator from MiGron**.

Turns out this machine is stable at 31.25MHz! Now if that doesn't take this 286 well into 386 performance territory, I don't know what will!

See the beautiful close-up pictures in this post (details in the alt-texts), and look for benchmarks and a hint of drama in the follow-ups!

Copper heatsink with embedded fan, mounted on top of the 25MHz 286 chip. The CPU is socketed and now that I have a heatsink glued to it, it's easy to remove the CPU from the socket! To my knowledge, this is the fastest 286 chip produced for consumer use.
The MiGron Any_Clk clock generator. It has a swappable crystal, and jumpers for configuration. The crystal gives it the base clock, and the jumpers adjust the multiplication factor - anything from 2x to 8x, with many steps in between. Pictured is a 25MHz crystal, and jumper set to 2.5x multiplier, giving 62.5MHz output. This gives a CPU clock of 31.25 MHz!
Picture shows a fancy blue passive heatsink on top of the 802C286 chip. After much badgering and being explained by the people of The Retro Web how the 82C206 chip is doing nearly as much work as the CPU itself, I decided to place a heatsink on it (despite it not actually getting hot at all, at least not yet..).

What's your recent nerdy (any kind of nerdy) impulse buy?

I recently made a somewhat silly purchase for my #gamingpc a used AMD RX 6800 16g graphics card (pictured outside and inside my pc) which I am having a WHALE of time #overclocking and undervolting.

It replaces my somewhat boring GeForce 4060 (last picture) which in it's defense is a rock solid power efficient entry level gamercard.
