ASUS P5Q3 Deluxe discussion

[neo_x]

Hi people,

I have finally gotten my system stable, and after some thorough research I ....

Hi Guys/Amurtigress,

Have you any recommendations on what I should set in the bios for my specs?


RAM:
Corsair XMS3 DHX DDR3 TWIN KIT 2X2048-1333 (1GBx2) X 2 (4 sticks of 1GB each, 2 dual channel kits) - model CM3X1024-1333C9DHX

Processor:
Intel Q9550

Motherboard
P5Q3 Deluxe Rev 1.02G, BIOS 1402

I have tried your settings without any CPU overclocking paramaters (e.g. CPU voltage was set to auto, and CPU ratio setting was 8.5, and memory speed was 1333 etc)

I have been trying to get things stable (e.g. memtest) with these parameters. I have even tried trfc set to 110 but still get errors within the first 10 minutes of testing.

One thing to note is that legacy usb is set to on in my bios , since I am using a bootable usb and running memtest off it. In the corsair forums they recommend to disable legacy usb support (but when I do this, I lose USB functionality). Should I test with a floppy instead ?

I have also read in the corsair forums that if I am to use 4 sticks then I should lower the memory speed to 1066 - if I do this, would I lose a lot of performance? Could I then have tighter trfc timings (I think a loose trfc can also lead to bad memory performance). Should I get 2 X 2GB instead?

I haven't tried with default bios settings btw - is that something I should do first? Lets say the system is stable at 'stock' settings (e.g. if I use 1GB X 2 only, or even 1GB X 4), does that mean the board will automatically downclock everything to a very slow speed for compatiblity (e.g. reset bios to default, then use memtest)?

Would appreciate any help, thanks
