Today I finally received the first batch of parts for my K6 system! The motherboard is a Gigabyte GA-5AX revision 4.1 with the latest F4 BIOS, it is equipped with a K6-III 450 MHz and 3 single-sided 256 MB memory modules which don’t work because the Aladdin V chipset can’t handle them…I will have to order double-sided modules.

A closer look at the ALI Aladdin V north-bridge, it’s branded with a “100 MHz” printing.

Then I tried to fit my Just Cooler P-600 Socket 7/A/370 CPU cooler but it didn’t fit due to some capacitors on the GA-5AX; some fins will have to go away…
The cooler does not fit with the capacitors…
…and here is the (ugly) result after 3 minutes of work with my Dremel. It now fits perfectly! I have ordered another better cooler though but it didn’t arrive yet.
A little Dremel later, it fits…
The case I chose for the K6 is a low-cost but still nicely built Thermaltake V4 Black Edition which costs around 35€ without power supply. The interior is nicely black and no sharp edges stand out so for me it fits my needs…the metal is very thin though and it should be placed in a spot where you don’t continuously hit it with your feet.
The power supply is a new ATX 1.3 compatible LC Power LC420H-12 costing around 20€. It very probably doesn’t deliver the 420W it claims to and the build quality feels minimal…but for a K6 it should not be overloaded and thus provide enough stable power and it’s quiet.

The motherboard is now fitted into the case with all the expansion cards:
- ATI All In Wonder Radeon 8500 64MB RAM by Pinnacle
- SoundBlaster 64 audio card
- 3Com 3C905-C 100 Mbits network card
- Promise SATA-300 TX2 Plus SATA controller
- 250GB Western Digital Caviar Blue HDD

For the sake of keeping it somewhere, here is the VIA Apollo MVP3 chipset press release…
The Apollo MVP3 is a high performance, cost effective, and energy efficient chip set for the implementation of AGP, PCI, and ISA in desktop and notebook personal computer systems from 66 MHz to 100 MHz based on 64 bit Socket-7 super-scalar processors.
The Apollo MVP3 chipset consists of the VT82C598AT system controller (476 pin BGA) and the VT82C586B PCI to ISA bridge (208 pin PQFP). The VT82C598AT system controller provides superior performance between the CPU, optional synchronous cache, DRAM, AGP bus, and the PCI bus with pipelined, burst, and concurrent operation. The DRAM controller supports standard Fast page Mode (FPM), EDO, SDRAM, and DDR SDRAM. The VT82C598AT complies with the Accelerated Graphics Port Specification 1.0 and features support for 66/75/83/100 MHz CPU bus frequencies and the 66 MHz AGP bus frequency. Coupled with BDDR SDRAM II, the VT82C598AT allows implementation of the most flexible, reliable, and high-performance DRAM interface.

For the sake of keeping it somewhere, here is the ALI Aladdin V chipset press release…
Aladdin V / M1541/ M1543
Aladdin-V is the fifth generation 586 chipset from AcerLabs. It maintains the best system architecture (2-chip solution) to achieve the best system performance with the lowest system cost (TTL-free). Aladdin-V consists of two BGA chips to give the 586-class system a complete solution with most up-to-date features and architecture for the most engaging multimedia/ multithreading OS and software applications. It utilizes the modern BGA package to improve the AC characterization, resolves system bottleneck and make the system manufacturing easier.
M1541 includes the higher CPU bus frequency (up to 100 MHz) interface for all socket 7 compatible processors, PBSRAM and Memory Cache L2 controller, internal MESI tag bits (16K*2) and Tag RAM (16K*10) to reduce cost and enhance performance, high performance FPM/EDO/SDRAM DRAM controller, PCI 2.1 compliant bus interface, smart deep buffer design for CPU-to-DRAM, CPU-to-PCI, and PCI-to-DRAM to achieve the best system performance, and also the highly efficient PCI fair arbiter. M1541 also provides the most flexible 64 bit memory bus interface for the best DRAM upgradeability and ECC/Parity design to enhance the system reliability.
With the AGP interface design, the dedicated PCI_66 AGP interface can be concurrent with CPU and PCI interface. The deep buffer of the read and write buffer design makes the utilization of memory bandwidth more efficient. The interface supports AGP specification V1.0. Supports up to 128 entries table look aside buffer for Graphic Address Remapping Table (GART). The interface not only supports the AGP 66 MHz PCI protocol, but also the AGP 1X and 2X sideband address function.
With the concurrent bus design, PCI-to-PCI access can run concurrently with CPU-to-L2 and CPU-to-DRAM access, PCI-to-DRAM access can run concurrently with CPU-to-L2 access. M1541 also supports the snoop ahead feature to achieve the PCI master full bandwidth access (133 MBytes). M1541 also provides the enhanced power management features including ACPI support, suspend DRAM refresh, and internal chip power control to support Microsoft On Now technology OS.
M1543 provides the best desktop system solution. M1543 integrates ACPI support, green function, 2-channel dedicated Ultra-33 IDE Master controller, 2-port USB controller, SMBus controller, PS/2 Keyboard/Mouse controller and the Super I/O (Floppy Disk Controller, 2 serial port/1 parallel port) support.
The built-in I/O in M1543 is an advanced Super I/O controller solution to the basic IBM PC, XT, AT and notebook peripherals. It incorporates two full function universal asynchronous receiver/ transmitters (UARTs), a flexible high performance internal data separator with send/receive 16 Byte FIFOs. It is suitable for notebook computers since it has Serial Infra Red for wireless communications with other devices. It can swap your drives A & B. It features basic functions such as standard mode, enhanced mode, high speed mode. It supports SPP, PS/2, EPP and ECP parallel port. It also has a programmable baud rate generator. It has high performance power management for FDC, UART and parallel port.
Furthermore, Aladdin V is designed to meet the requirements of all socket 7 process-ors including business, multimedia and high performance CPU file servers.
I just finished the history section and it was fun to remember some old tech stuff and browse AMD’s old PDF files. I will try to extend the information in the following days and upload some PDF data sheets about 3DNow!, PowerNow!, CPUID detections.
Looking for these pdf files nowadays was way harder than some years ago as AMD seems to have wiped them from their website; there also seem to be lots of companies actually trying to sell them to you. How stupid.
14 years ago I bought my first computer with my hard-earned student money; it was a very affordable AMD K6-2 450 MHz, Asus P5A motherboard, ATI Rage 128, 128MB of RAM and was about half the price a Pentium III was selling for at that time.
Now I’m 14 years older and wanted to replay some games from this period; unfortunately they don’t run on modern hardware or operating systems…so I decided to build myself a “new” K6 system just for that purpose.
I decided it was about time to pay a tribute to the excellent CPU family I chose back then…as information and stories about old hardware slowly gets lost in the darkness of the web I opened this website.
