TWIN2X2048-8500c5d and GA-P35C-DS3R

[moforles]

Hi,

 

I was wondering what settings I should use in the GA-P35C-DS3R BIOS to achieve the advertised 1066 5-5-5-15-2T timings for the TWIN2X2048-8500c5d DIMMs.

 

Here's what I'm working with:

 

Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775

GIGABYTE GA-P35C-DS3R LGA 775 Intel P35 ATX Intel Motherboard

CORSAIR TWIN2X2048-8500C5D

eVGA NVIDIA GeForce 8600GTS 256MB GDDR3

Samsung SpinPoint HD501LJ 500GB

ASUS DRW-1814BLT (Black 18X DVD+R …)

Windows Vista Home Premium 64-bit (OEM)

 

Thanks for your help in advance,

moforles

Just use the tested settings and Voltage for the modules from the link in my signature.

Ah, by looking through the other postings, I see why I haven't been able to get my dimms stable at the test settings. I'm currently using four 1 gig sticks of Corsair 8500C5D Dominator RAM, and I suppose my P35C-DS3R board doesn't like that. Whenever I ran memtest86+, I encountered many errors on the first pass. Currently I have them running stably at 888MHz and 4-4-4-12 timings, since the stock FSB of the Q6600 is 266, and the next smallest multiplier below 4.0 (which leads to an unstable 1066 system) offered on the bios is 3.33. Do you think I could do better than this, either by increasing the speed or decreasing the timings? I allow the board to automatically set the voltage, and the voltage it produces for this setting is 2.1v (even though I have v1.2 sticks which require 2.2v at 1066 speed). Any thoughts?

You can try setting the Vdimm to 2.2V. I personally would do a slight FSB overclock as well which would have the added benefit of raising the frequency of the MCH which helps the 4 banks populated issue.

 

There's a sweet spot with the FSB raise, and the concurrent memory speed raise that can be found with some time and patience.
