compatability concerns


Paul Jay

Recommended Posts

I will be updating my system with Asus Rampage Extreme, Intel Qx9650 but like to use my corsair memory sticks which are two pairs of 1333c9dmx (for total of 8 GB). I've noticed thru the forums that it will probably need some tweaking of the bios to get all 4 corsairs to read. Here is where I would like to have some recommendations as to some bios settings so that all 4 are working. It doesn't seem like it will read all four with the default settings. Please make some recommendations. I appreciate your time and energy regarding this matter.

I have the Rampage Extreme and if you are going to try and find stability with 8GB of 1333C9, then I would advise you to first try 1066C9 and move up from there. I can not get 8GB to run stable with full speed on my board which is the same and many other's can not as well.

 

Here is a thread of seventy five pages with people using the same board. It's helped me tweak my system. Be sure to first update your BIOS to 1003 (latest) as it is the best BIOS by far.

I can help you with stability settings when you get the hardware.

Derek thanks for your reply. I can only work on this unit on the weekend. Thank you for your patience. I've installed the rampage extreme with the qx9650 and the ram 1333c9dhx. I've used the full 8 gb of ram. Windows was able to be installed and I kept settings at "auto" for the time being. At first I thought I would be lucky and everything seem to work well. Then it started freezing and occasionsally the bsod would show. I took out 4 gb of ram and the system has been running without freezing for the past 4 days. It seems reading all the post that there is an issue with the 8 gb and speed issues. I'm willing to sacrifice speed for stability though. Any suggestions on tweaking the system so that I could get the full 8 gb running and stable? I am new to the possible adjustments so that any help would be appreciated. Thanks,

Paul Jay

Thanks for the response. I went and performed the changes that you suggested and I kept getting a cpu fsb overclocking error. I ended up reverting back to auto on everything and made only one change to the dram freq. I changed it to 1066 and so far no freezing/BSOD after about 24hrs. That is WITH the 8 gb of ram also. If this stays this way I am content as long as there is no late onset of freezing/bsod. Let me know what you think or any other thoughts.

I agree with you. I did, however ask you to perform memtest. It would behoove you to do so. Also, for long term stability I would at least change North Bridge Voltage: 1.40v when you populate with four DRAM slots.

Hi Derek and thanks for your quick reply. I forgot to mention that I did the memtest and had no errors on any of the 4 mem sticks. I will go ahead and change the north bridge voltage as you suggested and see how things develop. I want to thank you for all of your help and time and energy with this matter. Especially I want to say thanks for your assistance in helping others as I see you have helped so many as I look at the various postings. Take care.
