My RAM is faster than what the mobo supports, but I should be able to fix that my adjusting the FSB.
I read this comment on Newegg reviews of the product.
I got this board because it was rated for DDR2-1200 Mhz. However it states nowhere that if you have 4 sticks then you cannot run it at 1200 Mhz. I bought 4x1GB for 4GB total of the Patriot 9600 DDR2 to run it at 1200Mhz but that is no go. I can only run it at 1066Mhz but at the same time, I was able to tighten the timings on the ram to 5-4-4-6-16, instead of the 5-5-5-12-32 that it was suggested to run. So the memory is not as fast but it operates more quickly when tasked. Guess that is a toss up.
So its definitely a memory issue. I've updated my bios, installed all my drivers, and its still not working. It looks like I need to set my RAM's FSB lower-I tried setting it to 1066 mhz linked but that was a no go. Any ideas? Please help me!
What bios revision does the board have? The reason I ask is that this seems to be a common problem with the 780i boards, but it seems to have been addressed in some cases by a new revision of the bios. Check the XFX site for an updated bios.
hey i just thought i'de let some one know how i was able to fix the exact same problem.
when i was installing vista ultimate 64-bit i was able to boot with 2gb of corsair, they were rated at 1066mhz but
since my nforce 750i ftw and also the 780i sli mobo officially supported 800mhz when i put in 2gb of my 1066mhz corsair it would revert them back to 800mhz speeds.
when i put in the other 2gb stick of corsair ram, it would BSOD.
what you have to do is go into the bios, change the ram speed from 800mhz to 1066mhz. then look on either the box or the back of your dominator ram
and see what voltage the ram is supposed to be set at. then change the voltage to your ram in the bois probaly from 1.9v to the rated voltage eg. mine was 2.1v so
i set it to that and it boots up fine and at the rated 1066mhz speed. also check the ram timings and make sure there set right aswell. i had to change mine
from 5-9-9-32 to 5-5-5-18 as thats what its factory rated at.
1. change speed from 800 to ______ ur rams native speed. (in my case 800mhz to 1066mhz) 2.change timings from _ _ _ _ to _ _ _ _ ur rams native timings. (in my case 5 9 9 32 to 5-5-5-18) 3.change voltage from _._ to _._ur rams native voltage. (in my case 1.9v to 2.1)
I am having this EXACT same problem only with my Evga 780i sli ftw mobo. I talked to evga twice, no luck, tried calling Gskill that was a waste. But everytime I change settings on my memory in the bios it'll just do a long beep and revert back to normal, so I can start windows. The one time I was able to get into windows it BSOD on me. I tried manually setting all the memory to native settings, with no luck, I'm officially lost.
