Perhaps something to look in to.
Since i flashed the my bios to the Merlin cpc on bios I noticed performance increase. But only marginally. I increased 3dmark01 from 17800 to 17900. Aquamark also increased about 200 points. Your performance increase was much more. I have developped a theory about it after reading the nf7sFsbsense.html page. Perhaps it's BS or perhaps it isn't.
I connected ah32 to ag31, the lower mod in the left picture. Which made me boot at 166 mhz default. I assume you did the higher one on the left picture (ah30-ah28) as described in the table below. Which makes you post at 200 mhz default. Perhaps my mod made me use the 166 mhz romsip table even if i boot at above 200 mhz. Therefore, i only benefit from the CPC on setting and that would explain the minor improvement in performance. I am on par with your benchresults at 11.5x200. That would also explain why i did perform a lot better in superpi (posted in your memory bandwidth thread). I am using winxp of course and if you did the same mod as I did my theory is down the drain
