So is having a lower voltage than the 1.65 to say 1.5 make ram more stable then? I really thing setting it to auto is not the best choice now.

I assume that with my system it auto selects dual channel. Correct?

Only if you use lower frequencies as shown in the CPU-Z. If you use the X.M.P. profile, I would go for the 1.65 voltage. Nick N, in his guide on setting up FSX and tuning it, suggests setting your memery to the lowest frequency.Best regards,Jim

Ok I just had to share this with you...I managed to get home thins last weekend and changed my RAM to 1.65 volts, the updated my FSUIPC to the lates version. I HAD NO AND I REPEAT NO CTD AT ALL!!! I even used the latest Carenado Piper Malibu at YBBN under Orbx with ASE and many clouds. I was using the Reality XP GNS 530 and flew for 1 hour and didn't even have a g3d.dll crash. That one have been a plague for the Orbx YBBN area since I bought it. I've never been able to get off the ground let alone airborne from that airport without a g3d.dll CTD. Now that hase been fixed through FSUIPC. I checked the event log in the moduals folder in my FSX drive and found that the sim had 5 g3d.dll crash attempts but FSUIPC trapped them and prevented the sim from crashing. AMAZING. I had no other CTD at all. If you don't have FSUIPC get it it will save you so much frustration and make FSX much more stable. Also on the FSUIPC log I had an average frame rate of 44.6 in the YBBN and the serounding areas. All my slider were maxed except for water. That was one notch from the right. Also I had my traffic 5.2 and 70% for airlines and 50% for ga trafice 16% for cars 40% boats and ships and max for airport traffic.
