Dear G.Skill,
Thank you for helping me with my Ripjaws. With two sticks of 4GB DDR3-1600 (set to auto in the BIOS), everything runs great. The BIOS for my P5Q3 Deluxe/WiFi-AP @n really gets crazy with the amount of overclocking available to me. I don't know what 1st, 2nd or 3rd memory information means, so I just stuck with what you said, and a little common sense.
Here is what I did to run my Ripjaws at 1600MHz...
I think I set everything correctly. My system does seem to be running the Ripjaws at 1600MHz. And as evidence from the FSB bump from 333 to 400 , my Q9550 rated at 2.83GHz is now zipping along at 3,400MHz with only a ten degree rise (farenheit) in idle temps. My system is stable and there is a noticable performance increase.
After setting the first line in my Ai Tweeker Page in my BIOS from Auto to Manual here is what I changed....
FSB Frequency [400] ...this was a manual data entry which I typed in myself. It was 333.
FSB Strap to North Bridge [400] ...I don't know what this does, but I was able to select this from a drop down menu. I could not select DDR1600 unles I set this to 400.
DRAM Frequency [DDR3 1600 MHz] this was also selectable from a drop down menu.
DRAM Timing Control [Manual] this was set to auto.
CAS# Latency 9 (was set at 5)
DRAM RAS# to CAS# Delay 9 (was set at 5)
DRAM RAS# Precharge 9 (was set at 5)
DRAM RAS# Activate to Precharge 24 (was set at 15)
The last four entries I thought was the most logical place to input the memory specifications of 9-9-9-24. There were about forty other memory and cpu lines that could be fiddled with, which I did not touch. I left all the voltage settings alone, all set to manual. If I am considered an overclocker now, I consider myself a very mild one.
Again, thank you for your time to answer my letter. I am hoping to install another two sticks of your Ripjaws soon. I am very thankful you have a forum to talk about these things. When you work alone, it is nice knowing there is help out there.
Sincerely,
Terry.
