Hey guys. I'm trying to achieve the advertised 1066MHz memory speeds on my Gigabyte P35 DS4 Rev2.0 Using Corsair XMS 4x1GB 8500C5 chips (ver2.1). There are no support forums for Gigabyte, and asktheramguy (Corsair official forums) hasn't been to helpful so far...
Gigabyte has a memory compatibility list
http://www.gigabyte.us/FileList/MemorySupport/motherboard_memory_ga-p35-ds4.pdf
and this specific model of Corsair RAM is listed as compatible PC8500 memory(which is why I bought it). Well, I'm having one hell of a time getting this to work properly.
The board wants to default to 800MHz if I set everything to auto, it runs the memory at 5-5-5-18 (although the specified timings are 5-5-5-15) and it runs it at 1.8v. I have 2 more sticks of this exact ram in another machine and it is known good, so I did some swapping to be sure all 4 sticks were good to go. I'm getting very little help from Corsair, but I've the the memory running at 1066MHz @ 2.114v with the FSB and NB/MCH both clocked up +0.05V. I have tried most voltage settings and I'm losing hair here. Can anyone suggest what settings I should use to achieve 1066MHz STABLE on this Motherboard? Do I need to bring the FSB down? If so, how do I do that? Sorry for all the questions, but I'm running out of time to RMA if this memory doesn't work out for me and I'll be stuck with these errors for life
