Just got around to paying attention to my RAM timings again, and noticed it was set to 2:1 ratio, which read as DDR400. Now, I thought that 1:1 was better, as there wasn't a divider sucking up bandwidth between the CPU and the RAM. So, I set it to 1:1, which read as DDR200. Of course I got better timings, but it read the RAM FSB as 115 Mhz. So, which is better, 2:1 or 1:1? BTW, it's a s754 AMD64 rig.
1:1 if im not mistaken means same fsb on processor and ram. where as 2:1 is twice the fsb on the cpu as on the ram.
If you're working at DDR speeds, 2:1 is what you want ie. if fsb is 200 you want 2x200=400DDR etc. I got the impression some mobos needed 2:1 set in bios to get a 1:1 ratio (either that or I've seen many confusing posts in forums). Basically you want your ram to run at 2xFSB (or HTT) whenever possible. Hope that makes sense.
Could be that you've got maxmem set to 100, (or whatever the equiv is on your mobo) which is dropping the mem speed.. 1:1 is better, but the divider doesn hurt the 64's as much as it did socket A...
If you have 3200 as your sig says, then you should work it out 1:1, 1:1 is always better because you don't loose any of the system memory performance.
The 1:1 benched ~700 points worse than the 2:1. I dunno why my mobo is like this, but as long as it runs faster, I guess I'll go with it . I may venture around the BIOS and see if I can't figure something out later.
