Asus P55TVP4 at 400mhz

I have done quite a bit if research and checking to see how far I can upgrade this motherboard. It seems that this board (slot 7) is the less popular of this series with the P55T2P4 (I believe that is the number) being the most popular. Even though the boards are very similar there are some differences. My board (P55TVP4) seems to have been more popular in Europe because I found a lot of information from German and Russian posts, but of course they were of little help since I could not really read them. I also checked the Asus site quite a bit, and it is very helpful... but really did not address my specific issue. Aside from the normal upgrade of memory and cache, I wanted to increase the Pentium 166mhz to a faster system. My main goal was to max out the board to squeeze out another year on the system and to get a new larger harddrive and the new DVD drive to play movies. I had already overclocked the system to 200 mhz and maxed out all memory. I also installed the 40 gig harddrive. While trying to get the hard drive installed, I realized the bios would not support it and in the process flashed an inoperable bios and had to have the chip reprogramed. I also started looking for a CPU upgrade and settled on the AMD K6-2 300mhz. I needed at least 300 mhz for the DVD to work. The biggest challange was making sure the dual voltage setting on the MB would not fry the CPU. This board does not allow the exact voltage setting recommended, but you can get very close and within the range specified by AMD. I also did not want to make any board mods or socket/jumper solder mods. I wanted plug in capability. Apter adjusting the voltage jumpers I installed the K6-2 300 mhz CPU at the 3X setting. This worked, but still not the 300 mhz I was expecting. Then I remembered reading that these chips have a special 2X setting that actually produces 6X preformance. I reset to 2x and now the CPU is running at 400 (399) mhz. The fan was the next challange. I knew the standard Pentium socket 7 fan and heatsink would not be enough to keep this system cool. So I purchased a new socket 7 compatitable fan and a huge heatsink. It had a 3 pin connector (RPM) but I only used the 12v red and black leads and spliced into the power connector where the old fan was. Now the system is running well and at peak preformance. The DVD runs well and in windows the full 40 gig is recognized. However, while booting, it still only see the 8 gig limit. Time will tell if this is an issue. I know I could probably purchased a whole new system running at 3 times the speed for about double what I invested, but what fun is that!!! If anyone wants any detailed information on this upgrade, feel free to let me know.
