486 DX4 100 CPU and Cache Upgrade + Benchmarking

4K upload working now here:    • 486 DX4-100Mhz CPU and Cache Upgrade (4K R...   NOTICE: This video is still stuck at 360p. I uploaded it last night and it's been "processed". I've waited about 15 hours for it to process to 4K but it seems to have failed. I tweaked the video and re-rendering it as I type this. It's got about 50 minutes to go then will take another 3 hours to upload on my home internet. The source file is about 9.5GB. D: Thanks all! Also 101 Subs! Thanks for the supper guys and gals! Update (11/4/2019): This original video is now 4K finally. Just going to leave both videos up and be more careful about waiting as long as I need to for the video to process to 4K. Taking the new old stock 486 I put together earlier this year and replacing the IBM 486 DX4 100Mhz with a 8K L1 Cache and upgrading it to a AMD DX4 100Mhz with 16K L1 cache, benchmarking it then upgrading the L2 cache from nothing to 256K and doing some more benchmarks. This video didn't really go as I expected but I hope you'll find it interesting. It was certainly a learning experience for me.
