P35-DS3L w/ 1GB x4 Dominator 1066 DDR2

[Solow]

I am running my P35-DS3L machine with 4 sticks of Dominator 1066 DDR2 with a mild overclock to 3.03 GHz on an E6550 C2D. I mostly run Leopard 10.5.5 and occasionally XP SP3. Seems to run stable so far but in the past I have had troubles with data corruption using over 2 GB ram. I searched this forum for advice and came up with the following settings using the F8 bios. It doesn't seem to have all the possible settings that I found in the template file filled out below though. Perhaps this template is for a later bios than F8?
Anyhow let me know if my settings are reasonable for this level of ram and overclocking.

TIA,
Solow

Well those settings are in all BIOS's, but when you flashed to F8 you did load and apply optimized defaults right? Please read this for more flashing info and tips regarding loading optimized defaults >>>

http://forums.tweaktown.com/f69/bios-flashing-how-qflash-guide-27576/

Anyway, if you still are not finding those all you have to do is Press Control + F1 on the MAIN page of the BIOS then go into MIT Section and you will find them

Here would be optimal settings for what you mentioned above >>>

CPU Clock Ratio ____________ [7]
Fine Clock Ratio ____________[0.5] << your CPU does not support this, so 0.0
CPU Host Clock Control_ [Enabled]

I did the bios update months ago and likely did not set optimized defaults. But I did it just now and then tried keying cntrl-F1 to get the rest of the settings to show up. So now I have these settings:

Robust Graphics Booster___________ [Auto or FAST]
CPU Clock Ratio ____________ [7]
Fine Clock Ratio ____________[0.5] << your CPU does not support this, so 0.0
CPU Host Clock Control_ [Enabled]
CPU Host Frequency (MHz)__________ [433]

I ran memtest86 2.01 for a complete cycle plus a couple of test #5 cycles with success. I'll run it overnight when I get a chance. So far all is well!

Thanks for the feedback and setting info!

Great to hear! Yes, please do run some longer memtest's as that may or may not be fully stable, but looking good!

Thanks,
Any comments on the choice of 1.25V for CPU Voltage Control? I copied that setting off other peoples listings.

Well all chips are different so what works for others may or may not work for you at any said speed. Is it Orthos stable? You also have to keep in mind what you set in the BIOS will be less in windows at idle and even less at load. You can track this amount with CPU-z
