There is probably room for improvement, but you need to change the cache divider.
The cache on the 700 MHz Athlon is running at 1/2 (350 MHz), which is actually the HIGHEST cache speed on all Plutos/Orions (and almost at the very limit of what the cache ICs can handle, without going out-of-spec).
Starting with the 750 Mhz model and up to 850 Mhz, the cache divider is set at 2/5 (so the cache on the 850 MHz Pluto will run at 340 MHz - less than the cache on the 700 MHz Pluto).
And as for the 900 / 950 / 1000 MHz Athlon Orion CPUs, their cache divider is set at 1/3 (so the cache on the 1 GHz model will run at 333 MHz, lower than on the 850 and 700 MHz models).
So, depending on how overclockable your CPU die is, you can switch the cache divider to either 2/5 (which will allow a safe cache operation for CPU clocks up to 850 MHz), or 1/3 (if you have a faster CPU die under the hood, allowing you to reach up to 1 GHz or even a bit more than that).
Some motherboards actually allow you to control the cache divider from the BIOS setup menu, but these are very rare. There are also some patches available for certain motherboard BIOS versions that can add this functionality.
Personally, these "software solutions" never worked for me, so I find it much easier to just move a couple of resistors on the PCB and be done with it.
PS: that's a very nice build, vad4r! 😀 And that Rage Fury Maxx is awesome (and, sadly, missing from my collection 😢 )
