Intel announced back in June that they would be soon releasing their first AGPSet exclusively for the Pentium II, implying that they would be giving up on the Pentium MMX and Pentium Pro line of chipsets. Sure enough, when September came around Intel gave us an expected surprise with the release of the 440LX Chipset, a chipset combining the best of the 430TX and 440FX chipsets.

The result of months of hard work and testing was a chipset, supporting only the Pentium II, with official support for AGP, SDRAM, the UltraATA HDD specification, and full PC97 compliance. The deep buffers between DRAM and the CPU remain unmatched by any other Intel chipset, and like the 440FX the LX supports a maximum of Dual Processors. The single chip design of the 440LX chipset is something you don't see very much in the chipset industry, but something you will begin to see much more of especially with some upcoming products from VIA as well as future Intel chipsets. To the left is a picture of the LX chipset:

The LX Chipset, being the first Pentium II chipset to support SDRAM, supports a maximum of 512MB of SDRAM and a whopping 1GB of EDO if you opt for the slower standard. Fortunately, the LX chipset is able to improve performance when SDRAM is used with it by requiring special modules with onboard EEPROM to be used to enable communications between the chipset and the RAM. However, older modules lacking this EEPROM still work with the chipset almost flawlessly.

    This motherboard was on my 1st PC. I was very disappointed when faced with the problem that DIMM and SIMM memory can't work in the same time. I used Pentium 100Mhz CPU on this motherboard :) Reply
