Corsair XMS 4400 and 3:4 FSB/DDR ratio problem?


Spree

Recommended Posts

I have Abit IC7-G motherboard and P4 2.8 FSB533 and 'till yesterday - memory Veritech CL3 DDR400 4x256MB. Everything was running well for 2 months at 3.6Ghz 172/215 FSB:DDR 4:5. And yesterday I've bought Corsair 1GB XMS TwinX kit DDR550, because I thought I will easly hit 172/229 FSB:DDR 3:4 (couse my mobo supports it), but it never happend. I tried everything, form Voltage, CAS latencys, everything...not stable, and it's just about 460Mhz for memory???? What should be the problem, I'm dissapointed couse I paid over 200 euros for this kit :[pouts: ?

Just because the setting is in the bios does not mean the system would be stable with any combination of CPU and memory. The Divider settings are there to provide support for older memory and that specific setting is a by-product for running the memory slower than the CPU. If you try to run the memory to fast it will cause a bottleneck in the chipset and will not be stable.

I would look forward till you can get a new CPU that will run at 800 FSB and just run the memory at DDR400 and O.C. your CPU. But you might look at http://www.overclockers.com to find a good O.C. able CPU like the 2.4C as they are not too expensive right now.
