So I have this old computer and from what I have been able to gather it has a socket 7 motherboard with a AMD-k6-pr166 cpu. I was wondering if anyone knew what the best upgrade for this would be. Thanks

Um not sure if you could find a cpu for that anymore i had a socket 7 a few yrs ago and tried to upgrade couldnt find a good cpu for it. that age is a dream anymore... IMHO. E=MHZ

Hi, I just went through a whole lot of that sort of junk with a socket 7 M/B I have too. It depends weather your M/B will support MMX which is ussualy determined by the voltages your M/B feed's your CPU. If it can support a MMX CPU the best you can get is a 550MHz K6 something, or a 233MHz P1. If not the best you can do is a P1 200MHz, there was another brand of CPU back in those days called Winchip which made a MMX CPU which worked on M/B's which wouldent support P1's with MMX but I dont think the chances of finding one of them are very good... The best upgrade for a system that dosent support MMX would be to add a COAST module to add 512Kb of L2 cache for the CPU. I have an old Cyrix PR166+ running as a PR200+ (150MHz) and I added a COAST module for 512Kb L2 cache, it happly runs Damn Small Linux to my amusement... Now this system has more L2 Cache than my main system! LOL Hope this helps. P.S. The best place to find parts for this system is probably e-bay or computer markets..

It really depends on the board. If it supports the lower voltage requirements of the K6-2 (usually 2.2v), you should be able to slap in a K6-2/400, possibly a K6-2/450. The trick with all K6-2's is that the 2.0x multiplier setting is recognized at 6.0x, so even if the board only supports up to 66MHz FSB, you should be able to run a 400MHz CPU (6 x 66MHz = 400). If the board supports 75MHz FSB, you should be able to run a 450MHz CPU (6 x 75MHz = 450). The CPU voltage is the important thing though... If the board is based on an old Intel chipset...430FX, 430TX, 430VX, it would be best not to install more than 64MB of RAM. It will run with more, but the cacheable limit is 64MB. Exceeding the limit will hurt performance. The 430HX chipset also has a cache limit of 64MB, but IF the board is equipped with the proper "tag RAM chip", the cache limit goes up to 512MB. http://www.geek.com/procspec/chipsets/s7intel.htm

The best upgrade for your pc would be a new pc. Other than that, ^^^^^ what that guy said.

The K6-2+/III+ CPUs are designed for a 100MHz FSB but can also run on a lower busspeed. Because the maximum multiplier for these CPUs is 6, you are limited to 500MHz on a 83MHz FSB, 450MHz on a 75MHz FSB, and 400MHz on a 66MHz FSB. Unfortunately, boards without 100MHz support have almost never K6-2+/III+ BIOS support and the older 66/75 MHz boards often lack the 2.0V or 2.1V Vcore setting. So this page focuses mainly on support for the 100MHz Super Socket 7 platform, but I will include other boards when possible.
