Khenglish Posted May 21, 2018 Share Posted May 21, 2018 How did you get the 20% fsb overclock? I have only done 33% overclock via PLL hardmod. On the inspiron 8600 I can't get any software overclocking tool to read the clock generator. It would be great if I could add fine grain overclocking on top of the 33%. I have a respectable 745 CPU that does 2.4 GHz at 1.33V. Also it looks like your CPU throttled. There seems to be a hidden CPU power limit on the i8600 series that you need to disable with RMclock. I get 1K CPU scores in 3dm06. Quote Link to comment Share on other sites More sharing options...
Ginner Posted May 21, 2018 Share Posted May 21, 2018 I used SetFSB 2.2.134.98, I can't remember which exact setting, since it's 8 months ago I did it. I won't be home to check until maybe next week. Though I curious as well to know what it took to hardmod til PLL chip :) All I can tell you right now, is that I can see from photos that it's a Cypress PLL chip. Will investigate and return with an answer. Quote Link to comment Share on other sites More sharing options...
Khenglish Posted May 21, 2018 Author Share Posted May 21, 2018 Ah, I have a different IDT PLL. I found the Cypress PLL on mouser for $2.80. I'll buy it and switch it out. Messing with old cheap hardware prevents me from messing with and killing my $1k+ stuff. I'll be back at this system tomorrow and can get hardmod info. I think all I did though was solder pins 54 and 55 together. The resulting intermediate voltage gets interpreted as a 1 by the PLL on both frequency select pins. Beware that you memory likely can't handle 444 MHz. I knocked mine down to the 266 MHz strap for 355 MHz.

Khenglish Posted May 21, 2018 Author Share Posted May 21, 2018 Actually the Mouser part listing is for 2000 part reels... Quote Link to comment Share on other sites More sharing options...
Khenglish Posted May 23, 2018 Author Share Posted May 23, 2018 Yeah I did just solder the S0 and S1 pins together and that got me 533 fsb. Also, you can put 9600xt and 9700 mobile cores on these things: https://imgur.com/a/RuTX2ah Quote Link to comment Share on other sites More sharing options...
