FSB WALL TESTING RESULTS AND A CONCLUSION

I did some work last night regarding FSB wall on this board....

P5W DH deluxe with Bios 1101
E6700 OEM Step 6 B2
2GB OCZ 6400 Plat 4,5,4,15

Results:
I have been having real issues at 380FSB and Above. I tried out an E6600 and that worked up to 400FSB, but no higher.

Another post of the foum put me onto crystal http://crystalmark.info/download/index-e.html which lets you change the multi in windows on this board.

So I tried the E6700 at 9x and 8x to see what happened.
The only Bios setting that helped at all was to set the ram to SPD - no voltage changes let me go higher than 379FSB. With SPD on i could do 410FSB before it would go no further. I should point out that SPD sets my ram at 5,6,6,20 - miles out from what it should be.... this got me thinking...

Next I booted with SPD settings and used memset http://rv.page.cegetel.net.perso.cegetel.net/MemSet.zip to see all the ram settings. I took a screen shot and saved the memset settings.

Then I rebooted changing back to manual RAM settings in the bios 4,4,5,15

When in windows I opened memset and changed all the settings apart from 4,4,5,15 to be the same as the screen shot at SPD.

I was then able to go right up to 440FSB before i suffered any issues.

Summary:
1. FSB Wall at 380FSB with manual Ram settings in Bios
2. FSB Wall at 400FSB with SPD ram settings in Bios
3. FSB Wall at 440FSB with manual Ram settings in Bios but changed to match SPD in windows with memset.

Conclusion:
Asus need to provide access to far more RAM settings in the Bios. This might well be the cause of the FSB wall and would explain why different people get the wall at different points... down to when the RAM fails due to its settings.
Wonder uis Asus read this forum... maybe a bios with access to all ram and some multi adjustment like the Gigabyte boards would be good.
