No. It is like value of the computer went down sudden if I hear anything that is considered important that potentially fail and SSD *is* finite endurance. Endurance means finite use and finally fails, much like hard drive does. Therefore *MUST* be replaceable helps with value of the console or …

I don't like any cases that have ports angled at a angle upwards even straight out horizontal at top. Easy to get knocked against and break in the process when reaching to the front drives or moving across front of computer. Cheers,

PIII Speedstep is only 2 states as opposed to later ones that allowed fine grained multipliers to actively adjust performance to extend the battery life a bit. PIII have Low and standard multipliers. This depends on standard speed dictates the low. PII does not have speedstep. Look in this links. …

This could happen if the chipset or TTL chip has one buried bad transistor that only shows up when specific item is used for example serial like in your case. I'm not surprised, I had a TV with one transistor cell is bad in EEPROM IC and microcontroller had one bad spot somewhere. Shows up on one …

This means this motherboard is the issue with serial function in particular. Could be in chipset itself or bios firmware not good. Only way is replacement after confirming the bios firmware is good. I use diode reading using black probe on the pins and red probe on ground to make sure the transistor …

Had to pay lot anyway. Once here, this adds to my first, which these two cases, will be intended for PIII and …

Absolutely correct. If XT, it will have 8 bit board with 8 slot while AT class is always 286 with 16 bit board with 16 bit slots this what was kicked into motion by IBM. Same thing applies to clones. When 386 and 486 came around for the clones, done with third-party chipset kept using AT bus …

While doing some more tweaking on this build, and installing WinXP on a second drive for maintenance purposes, I noticed something odd. Seemingly at random, one of my drives would go into PIO mode, instead of using UDMA. This usually happened while copying larger files (500 MB and up) and could be …

Good for you, should had pay attention to cacheable range as well to rule out the performance, there is plenty of information on this chipset online to tell you what's cachable range memory to not be exceeded. Same issue with intel chipsets all of them is 64MB cacheable except HX with second tag ram …

A P2 450 running at 266MHZ would perform identically to the real 266MHz part correct? EDIT Nope: The 450 is a 100mhz Deschutes part, so I need to order a Klamath P2 close enough. as i recall, you can underclock just about any p2/p3 to a lower fsb. I ended up ordering a replace SL2HE 266mhz. I want …

This issue is not new. PS5 started using soldered SSD in 2020 at introduction. Worse, Xbox Series S/X started to tie both 2230 SSD to one particular hardware of SSD compatibility and data to each console. If the bit of data gets corrupted or lost, the console is considered parts donor. And you have …
