First, a brief introduction...   "From the Shop" articles come from experiences in an actual computer repair shop: Dux Computer Works.  Dux (pronounced "ducks") is a "mom 'n pop" business on "Main Street, U.S.A." in a rather obscure town--that's the way I like it--in Maine.  My wife, Claudia, is the "Mom" and, of course, I am the "Pop."  We have been doing pretty much the same thing since 1987:  fixing, upgrading, and building computers; building networks; installing software, etc.  Claudia, who works here part-time, does the bookkeeping, printer cleaning, cable and ribbon sales, etc.  I fix 'em.  The shop, shares the bottom floor of a house--which is almost as old as dirt--with Roy's Barber Shop, the best barber shop in these parts.

AMD K6-2 Processors with 66 Mhz FSBs.   AMD has been shipping 300 and 333 Mhz K6-2's with 66 Mhz Front Side Buses (FSBs) for about a month.  These processors are not certified to operate with PC-100 memory at 100 Mhz).  A decided step backwards, I would say.  They are marked, for example, as follows:


The problem is that someone who is not aware of this fact may order a 300 Mhz or 333 Mhz K6-2 processor, assuming it has a 100 Mhz or 95 Mhz FSB, respectively, and receive one with 66 Mhz FSB (and install it as a 100 Mhz FSB unit).   I received one last week with a Super7 board which I ordered for a customer. Although it passed preliminary testing before I realized what I had, I am sending it back to my distributor.

wpe6.jpg (12704 bytes)While I'm on K6-2's... how does a 333Mhz CPU, with a 95 Mhz FSB, stack-up against a 300 Mhz CPU with a 100 Mhz FSB (not the one mentioned above)?  It doesn't.   With exception of a slightly faster Floating Point Unit WinMark, the 333 Mhz CPU is actually (insignificantly) slower than the 300 Mhz CPU.  So, why pay more for it?

By the way, the Epox EP-51MVP3E-M (ATX) and EP-58MVP3C-M Super7 motherboards now support the 333 Mhz K6-2 with a 95 Mhz FSB jumper setting.  I don't know why they bothered.

At the beginning of this month AMD cut the prices on their popular K6-2 processors.  Most noticeable, was the 400 Mhz chip which has dropped more than $100 the last couple of weeks.  So, I bought one.  I've been running it since last Friday. To answer a question from a few readers, both of the Epox Super7 boards, mentioned above, run just fine at 400/100 Mhz.  I've had the CPU on the EP-51.... longer than the EP-58--I wish Epox would shorten there motherboard model numbers--and it is rock solid.  I did a Windows install on the EP-58... without a problem.  Before moving up to the 400 Mhz unit, be sure your BIOS is up-to-date.

Look for reviews on the HP 8100/8110i CD-RW drive, ATI Play98 video adapter, the ATI-TV board, the HP DeskJet 895Cse, and the long promised article on how to network two Win95/98 computers in the next few days, shop work permitting.
