As a consultant for many years of business systems, it always seemed better to recommend multiple processors when specifying server or high end workstation equipment.  Long before the Dual Core CPU came about were the multi-cpu boards and systems.  One of my favorite boards that hung on the wall for a long time was a dual 386 processor board.  It had two Intel 386, 33Mhz processors built onto it.  The board came out of an early server used in bank and financial transactions. Intel and AMD both have a huge business market for multiple processor systems.  Recently it was shown that personal computer shipments were down last year, but Intel made a huge profit primarily due to the server market. Even in todays multi-core CPU world, multiprocessor systems play a huge role, especially in virtualization.  I recently got to drool all over some servers we ordered.  The servers were only 1U rack space, 1.75" tall.  The amazing part were these servers hous...

In late 2004 Intel and AMD both were having huge battles in processors to see who could reach the top speed.  AMD stopped labeling their CPU speeds and instead started using rating numbers as names.  So instead of what we normally expected with an AMD Athlon 2.8Ghz to compete with an Intel Pentium 4 2.8Ghz, we now had an Athlon XP 2800+ supposed to be rated at 2800, but ran at around 2.1Ghz. Intel was reaching the four gigahertz speed barrier.  Without overclocking it seemed that neither company could reach or break the magical 4Ghz range.  At the end of 2004 Intel released a Pentium 4 Extreme Edition that reached 3.73Ghz. A true 4Ghz chip is listed on http://ark.intel.com, and a few engineering samples saw the light, but were canceled for the Dual Core chips.  AMD started banking on 64-bit and so the Althon 64 brand started to come about, but still kept the rating name instead of actual speed name. The name game starts at Intel in early 2005 with the Dual C...

So many times I have been asked this question throughout the years "Why not buy a Celeron?" and try to explain the answer in easy terms to someone. So in the great car reference so many times used in the computer world, I ask a person "Would you buy a car that part of the engine or transmission did not meet spec and so part of it is shut off?" The car will still get you from point A to point B, just not as fast or smooth as the same car with all the fully functioning parts. Only a few people would every decide that they could wait for the few dollars saved even though I tried to show that time is money and spending the extra could save in the long run. First chip binning, reusing, and relabeling has been going on in the processor industry almost since the beginning. Do you just throw away a working CPU that may not reach the intended speed or that part of the cache is not 100%?  No way, that would waste money and end up costing the consumers more per chip. You ...

The components of the following were OEM as well, but they are HP Compaq instead of Dell.  The nice thing about this board, it is pretty much a straight Intel board just labeled for HP. The board was repaired by replacing blown capacitors in which several manufactures around the same time frame were getting bad caps from their sources.  Unsolder and replace about 6-9 caps and we are up and running like new.  I prefer Rubycon capacitors, but will settle on Panasonic and a few other top names if the Rubycons are not available.  After a solder job the boards are put through a 24 hour burn test using the old Prime 95.  This test heats the components up pretty warm to test if there are going to be any more caps fail or a weak solder joint. The other thing I would like to say about this board, it is still quite popular today in the new form of an Intel Atom board with the chip soldered on.  Nothing like reusing 5+ year old technology all over again. Funny at t...

The next system I grabbed was more OEM Dell pieces.  Did I tell you I repair and replace a lot of Dells? I again assure you that the main components were running well.  I upgraded the Dell to a Core 2 CPU and Mainboard.

The first system I grabbed hold of may not be the oldest, but one of the older ones still running well. When I used to host LAN parties, this was always the faithful backup.  I removed the add in graphics card to get back to the bare root of the system.
