P5n32-e sli & Corsair 8500c5d

The nVidia 680 chipsets and MBs were flaky, so it may not be possible. Make sure you've set your RAM voltage to the value printed on the side of your DIMMs, then save that setting and reboot before trying to change the timings. With 4 DIMMs installed, you may also want to try boosting the northbridge/memory controller voltage a touch.

Agree. P5N32 arn the best for 4dim.

it's ok everybody. My system is very stable with my Corsair 8500 but at 800 mhz.Just can't fix the right speed in the setup cause the mb is not made for 1066 mhz native. It's still very accurate at 800mhz on 4 x 2 gig. Thanks anyway

Ok le québecois, j'en suis un aussi ! 8gig ram fonctionnent très bien avec vista 64 bit. Avec un système 32 bit, je sais que windows n'en voit ou utilise seulement 3.25. Merci mon ami.

Ok '' Le Québecois'' I'm a Quebecker too. Vista 64 bit works very well with 8 gig of ram. I know that windows 32 bits uses only 3.25 gig of ram. Thank you my friend

Hi

1066 ram is 800 ram that has been tested to run within the specified voltage range at the specified timings. The user must set the timings and voltages to run 1066.

Not many can get 1066 ram to run at that speed, usually 1000MHz and below is the norm. I have Consair Dominator in my other rig, stable at 960MHz. Start at 1066 and work your way down until you obtain stability.

Now that I'm on vista64, it's almost like night and day. Now I can figure out why the system used to crash or freeze from time to time. I thought it was Vista or some driver problem....but now I think it was the 4 x 1 gig ram double channel on a 32 bits system. J'ai pas planté une seule fois avec Vista64 et 4 x 2 gig Corsair. Everything works like a dream.
