Beware of over / under clocking

There is no question that over and under clocking could cause system instability that could lead either to loose of data or system hangs, so why write about this? Because system stability, as I found hard way, is also OS specific.

Common way to decrease system power usage is undervolting components so that way, even thought they do operate within same spec, they do use less power to do so. Less power equals to less heat being generated, so this also helps to decrease component temperature a bit.

sTRX4 Linux RAID driver

Switching from Intel HEDT to AMD HEDT, to be more precise from Intel i9-7900X to Threadripper 3960X was enjoyable experience. More then double the core count, very attractive pricing (relatively) and support for more recent technologies. Code compile is just flying …

Unfortunately not all aspects of new platform are smooth sailing and main problem is with driver side on Linux. Using RAID on Linux is practically impossible due to … lack of driver.

Disassembly LCD matrix on Compal FL90 laptop

A few days ago I noticed a bug (more like a small worm) on my LCD screen. First attempt to take it off failed, and I soon realized it was under my screen. Strange thing was that when i poke my screen with finger worm started to move. Unfortunately for me in that process (poking screen to “corner” it) i manage to kill it (or he just stuck in bottom corner of screen). In the end I got black area, similar to dead pixels.

Samsung HD753LJ and WindowsXP partition utillity

Samsung HD753LJ

Samsung HDD

I got my hands on this piece of hardware about one week ago, and first impression is rather nice. After plug-in it to PC everything went smooth, motherboard detect it without any problems [Asus A8N-E nForce4]. Next step that i did was run, under WindowsXP, partition utility to create appropriate logical drives. From that point win horror began. Read the rest of this entry »
