Okay I have tried a few different settings trying to get the highest OC out of my 1700 B on the 8RDA+ with 2 Elixer 256MB PC2100 running Win98 with the memory running SPD settings. I have had this config up to 177 x 12 with 1.9V and it was running fine but I got Prime errors after 30 minutes or so. I took it down to 166 still got errors. Now at stock speeds and voltages I am getting Prime95 errors. My temps are between 32 - 39C under load with system temps at 31-32C no matter what speed I am at. Do I have bad ram or is it something else? Any help will be great, thanks.
