I need some help please.


Recommended Posts

I cant get this setup to work with both sticks. They came as a pair of XMS2-8500 2048MB 1066MHz 2.10V Ver1.1 Dominator. (timings 5-5-5-15) I have tried to find the bios settings for these sticks on these forums but I cant find the exact set up that matches mine. I was told by the re seller that this motherboard would not need any tweeking to makle it work. I'm not into this oc stuff its way over my head. I just want it to go fast :D:


Can someone offer me a bios setup to make this expensive doorstop run at least close to its full potential?


At present I have the Dram Voltage set manualy to 2.1V and the timings set manualy. But when I put the second stick in the POST stops at DET RAM so with both sticks in I cant get to the bios. With bios defaults loaded it still fails the POST. I have run memtest on both sticks with no errors.

Thanks in advance.

now save the bios and shutdown the pc. insert the 2nd module and run memtest for 2 full passes. post cpu-z screenshots when you have passed memtest.
