ASUS P5K Deluxe - Intel P35 Bearlake + E6600 B1 / Q6600 B3

Okay can confirm 0404 bios has been tweaked with tighter latencies and more bandwidth that 0311/0403 bios.

With the below settings memtest86+ v1.70 reported bandwidth for the bioses are as follows:

• 0311 bios = 6015 MB/s
• 0403 bios = 6012 MB/s
• 0404 bios = 6250 MB/s <-- unstable for me at below settings errors in memtest which I assume is why bios hangs with the below settings. Tried disabling DDRAM Static read or setting sub timings at AUTO and made no difference. Raising NB volts from 1.55v to 1.70 helped lessent memtest86+ v1.70 test #5 errors but still they existed.

I flashed back to 0311 bios and same settings below are again stable for me. So I guess i'd need to loose subtimings more on 0404 bios to get things stable - I wonder if it will effect max memory clocking frequency though with 0404 bios versus previous bioses ?

Update: with 0311 bios and below settings i changed TRTP: from 8 to 3 and memtest86+ v1.70 reports 6249 MB/s bandwidth now close to that of 0404 bios but it's stable in memtest86+ v1.70 so far. I'd probably stick with 0311 bios for this reason
