Just learn today that Superclock4 cannot be installed on Samsung HD841. According to RAM, I was told that there is something wrong with HD841 (but it works and plays just fine with EOM Crystal) and when RAM installed the SC4 on it then it "FRIED" the SC4. From the conversation about 1/2 hr RAM, I've learned that this is the first time it (RAM) sees this issue and it is the first time that it (RAM) tried to install SC4 on the HD841. I am very sad about this situation... since I was told up front that "it will work and we've installed it many of these in the past".
I wonder any one out there tries to do this successfully?
