Well I think I understand what is depicted in that image. And indeed, for the most part the color coding you added matches the N/B Straps and their memory ratios from the Intel 975X chipset. However, note with the Intel 975X chipset the 1:1 memory ratio is available in three different N/B Straps. The IP35 series doesn’t have N/B Strap information in the BIOS. So how do you know selecting the 1:1 memory ratio invokes the PSB1333 N/B Strap and not the native strap based on the processor? For that matter how do you know selecting any memory ratio invokes a particular N/B Strap? I’ll add I tend to agree with you, I’m not trying to be a smart ass. I just want to know, as I asked in the first post, what do you base that statement on? Did you deduce it? Did you read it in an Intel white paper?


Abit AW9D Max N/B Straps and Memory Ratios
PSB533 N/B Strap
DDR2 400 = 2:3
DDR2 533 = 1:2

PSB800 N/B Strap
DDR2 400 = 1:1
DDR2 533 = 3:4
DDR2 667 = 3:5
DDR2 800 = 1:2

PSP1066 N/B Strap
DDR2 400 = 4:3
DDR2 533 = 1:1
DDR2 667 = 4:5
DDR2 800 = 2:3

PSB1333 N/B Strap
DDR2 400 = 5:3
DDR2 533 = 5:4
DDR2 667 = 1:1


Yes, I am a Mod at Abit forums. Ace-a-Rue should be aware of that. That should have nothing to do with my question(s). I know it doesn't for me.
