I have a Gigabyte super socket 7 mobo, with an Intel Pentium 233MHz MMX CPU in it. I have been reading the manual, and wondered if it's possible to overclock the system bus (and CPU) to 105 FSB?If I set the CPU's multi to 3x (from 3.5x), this should yield a speed of 315 MHz.

Having my working K6 system since a couple of weeks now I began tweaking the BIOS settings for my Gigabyte GA-5AX rev 4.1 to find the best performance, as it took quite some testing I’m now sharing what I found ? First of all let’s remember the system: • AMD K6-2+ 550 MHz • 768 MB PC133 CL2 RAM • nVidia GeForce 3 Ti200 64MB • Fast SATA HDD • Windows XP SP3 I began by setting reasonably good BIOS settings and after each individual setting change I ran a series of 5 benchmarks using the good old Quake 3 v1.32 with “timedemo 1, demo four”. Quake 3 has the advantage of giving very consistent and reproducible results over any other benchmark tool and after all I’m using this system for old games The first tests I made is not BIOS related thoughI tried to find the best nVidia driver working with my card. The 23.01 gave me an average of 28 FPS and the 21.83 WHQL an average of 28.7 FPS so there is the first baseI’ll be using the ForceWare 21.83 WHQL for the rest of the tests. Now I’ll go trough each BIOS setting and give the fps change from this baselinenote that the changes are “incremental” by always keeping the previous test’s best performance. Primary Frame Buffer • 2 MB (BIOS default): 28.7 FPS • All: 28.2 FPS • Disabled: 28.8 FPS VGA Frame Buffer • Enabled: 28.8 FPS • Disabled: 27.7 FPS Data Merge • Enabled: 28.8 FPS • Disabled: 27.7 FPS Tweaking “IO Recovery Period” or “AGP Texture Size” didn’t change anything. Then I changed the CPU from an AMD K6-2+ 550MHz to an AMD K6-3+ 550 MHz to see how the 128kB additional L2 cache influenced the result. Well the fps jumped from 28.8 to 31.1 FPS which is nice!

As you can see I wasn’t that wrong with my default configuration as I only managed to “lower” the result by tweaking some settingsthat’s experience talking ? Here are the pictures of my final best result settings.
