seems like this motherboard has been around forever. I know I've build 4 machines with them
Any idea how many of them have been sold?

I built quite a few from the Fry's dealie of the week. But now they have the K7VTA3 instead, because many of the others were returned. They have a tendency to loose their bios settings every so often, or if you power the board down while it is initializing. Most users start having problems at that point and have no idea what to do.

This board has been around for well over two years, and must have sold two or three dozen MILLIONS. Around this time last year, it had already been said to be the best selling mainboard ever in PC history.

It's time to wave it farewell though ... neither PC-Chips nor ECS list it as an active product anymore, and retail availability is going down the drain really fast now.

I like this board. Of the three I've had, all of them have been running for nearly two years now without any problems.

Brian,
I checked your "My Specs" on Box #4 that has the K7S5A mobo. I'm building a new box with the same mobo and same Allied 400W PSU. I was wondering if you had any problems putting you rig together? The only difference between your rig and mine, is that I will be recycling some SDR (PC100 and PC133-256MB/per stick). Just wanted to know if your experience building your machine was trouble free. Thanks
:D

When you're recycling PC100 RAM, note that your CPU will have to run 100 MHz bus too. This means, you need to use an old Thunderbird "B" Athlon, or a Duron 1.3G or slower.

The reason is that the board can do CPU/RAM clock 100/100, 100/133, 133/133, but not 133/100.

But you can run any newer Athlon XP chip at the lower 100mhz bus speed on most mobos, including this one.

...or you could get an L7S7A2 and officially use up to the 166MHz CPUs.
It would be interesting to see how many K7S5As have sold, though.

L7S7A2, officially, is 133 MHz too. 166 MHz is available, but not in-specification of the chipset. They've been using the SiS 746 there, not the 746FX.

The "748-A" board is a revision of the L7S7A2, using the 748 chipset. That'll do. Also available in that price range: PC-Chips M848 v2.x, also using SiS 748.

OK, I'm using ECS' 'official', not SiS's :), and the fact that it has worked on near 20 PCs (and counting, a few more today even) so far out of the box.
