Experiences with Overclocking a Cheap MSI Motherboard

tfw u boot into your pc @ 5ghz on air cooling

I guess the moral of the story is, don’t try to overclock a CPU on an affordable MSI motherboard. It just, kind of does what it wants. Basically I can overclock just fine from the Command Center program and set the turbo speed to what I want it to go up to.

So if I’m rendering video, CPU can now go faster than normal, but if I’m doing nothing, it slows down. Makes sense so far, right?

Now the command center program cannot make permanent changes to the system. Well that’s okay. That’s not the end of the world, you figure out what settings you want, then go to the bios and change them. So I can be stable at 4.5Ghz on air cooling. Cool. That’s a base clock of 100, and a multiplier of 45. Go to BIOS, change ratio to 45, boot it back up and be good, right? Well upon reboot, it was running 5Ghz. Well that’s not what I set. And it was staying there, yes programs are loading, so on, no worries.

Okay, fans cranking, programs are loaded, Utilization is a few percent, and it’s just roasting away at 5GHz. That’s, starting to look bad. Playing around with a few more settings, it actually boots at 4.5Ghz…and stays there. Still not what I’m going for. Sure there is a one button overclock built into the motherboard, but if it can’t handle me changing a number manually, I don’t want to see what it will do automatically. The voltage limits they tend to set are sketchy, and I doubt it would accept a change. At that point I gave up, and everything is back to default. I don’t even know if I ended up with XMP turned on for my RAM, but that’s enough for today.

And upon opening the Command Center, it has my settings. So I have no idea how any of this works. Considering it’s a dice roll for the program to load. So I guess if I wasted this hour, but ended up with a 7% overclock, I will make up that time in 14 hours.

tldr; Overclock cheap MSI boards with the Command Center and just cross fingers it works, don’t go to the BIOS.

Teardown of the HP C200 Digital Camera, a 1 Megapixel camera!

Most of the chips in it are so specialized that I couldn’t find any info on them, but I try to go over what I can with it, as well as show how much power it draws.

TI-55 Calculator

TI-55 Calculator Battery Replacement

 

How I made my TI-55 calculator work. THE THING HAS AN LED BUBBLE DISPLAY.

Want to breath new life into an old calculator? The TI-55 was one of the best in the line of scientific calculators with statistical capabilities back in the 70’s.

The TI-55 has an LED-stick using LED chips mounted and bonded to the printed circuit board, and has some 12-digits instead of the 9-digits of other calculators from the same time period.

The TI-55 calculator used a rechargeable battery pack rather than using a 9V battery, so when the rechargeable no longer worked, your battery was dead. However, the voltage and current used in the rechargeable works out to be still, 9V capable, so this video shows how one can easily adapt the TI-55 for use with a standard 9V battery.

Any Scrappable Parts in Old Phones?

 

Are there any parts in old land line to even slightly “modern” cordless land line phones worth salvaging? Let’s take the scientific approach and tear down a bunch of phones to find out!
