Rampage Extreme and TWIN3X4096-1600C7DHX

[iwolke]

I'm running a Rampage Extreme, Q9650 and 8 Gb (2 * TWIN3X4096-1600C7DHX) at 4,43 Ghz (FSB 490). DRAM speed 1643 Mhz.

 

The problem I'm having is that the BIOS recognizes the memory at a 9-9-9-24 speed only. When I set the 7-7-7-20 manually the system becomes very unstable. I've already tried replacing 1 set of DRAM, no result. Also when running only 2 sticks I get the same result.

 

What can you recommend to get the faster timings and will I indeed notice an improvement if (when ;-) I get it to work?

Can you please list all of the settings in BIOS you have made for the voltages, RAM, and CPU? What RAM voltage are you using and what memory controller voltage have you set?

I have this same board and it is VERY problematic. It's not the DRAM, it's the chipset. You are attempting to run 4 X 2048 with 1600Mhz? Good luck! I couldn't.

I have found full stability with 4.0Ghz and 1500Mhz on the DRAM with 7-6-6-16 1T. I needed quite a bit of tweaking. W Please read this thread. There are a lot of people with Quad Cores who are not impressed with paying 500.00 for a board with these issues.
