小弟在改造失敗以後，還是很不死心的寫了一封MAIL去問那位改造者Katsumi，他也很快的就回應我了，但是我不太確定的是說他後來說的R730和R746必須被焊接，是要短路嗎？還是要在銲上兩個103K的電阻呢？
他最後好像說了他改造之後發現並沒有多大的改進，不知道我理解的是否有誤，希望大家一起研究，加油嚕！！！



GeForce4MX440 -> Quadro4 550XGL
and I did it.

Hmm... It seems that R730 and R746 must be soldered from my experiences,
but I don't know another reasons/cases.

> By the way, what is the value of R728?
--
R728 is blank in my Quadro setting.
I removed R728 chip and re-soldered it at R729.

I tried SPECviewperf and SPECapc-Pro/ENGINEER2000i2, but
disappointigly, there is no performance improvement by this modification...

Thanks,
Katsumi
