I am upgrading from 4 gb(2x2gb) to 6 gb (3x 2gb) on my 790i Ultra. Im wondering what is the best way to layout the sticks in the motherboard. I currently have the 2 sticks in the 2nd and forth slots (from the left) Any special way to put in 3 sticks? I know this motheboard worked better for me in the 2nd and 4th slots with 2 sticks. Old sticks are ocz reaper 1333 and ive now got Patriot Viper II Sector 7 ddr 1600 3gb

what should i get then?

those look good but id like more ram. I like patrio seeing as most people with this mobo use patriot viper and seems to work very well. Any suggestions on 1600? How bout these? http://www.newegg.com/Product/Product.aspx?Item=N82E16820220484

thanks for your help, im gonna buy 2 sets of the ram you mentioned. :) Might be back with another question when i receive them.

Jeffreyham, 


Thanks for your help.  You are proving to be a real asset.

Ok jeffrey, so i got my new ram and im running it currently unlinked because i do not overclock my processor. Is there something i need to do to sync it at 3ghz processor and 1600 mhz ram? Or do i have to do unlinked for that to work?

Jeffrey, i got 8 gigs but cannot get it to post with link and sync at 3.6 or 4.05ghz. Keep getting c1 on the bios LED chip. Right now im running 4 gbs at 3.6ghz @ 1600mhz ram. Running fine so far. Havent done a test with the game that crashes yet. Any ideas on how to get 8GB to post and run correctly?
 
edit: Just tried the game, worked fine for a long time then a hardlock, what should my other timings on the memory be beside the 7-7-7-20? I have it at 2t and all the others at auto, but i assume there still needs to be more tweaking with the other timings?

Well i cant post at all with 8gb at 3.6ghz and 1600mhz.

if you wouldnt mind posting your settings for 4gb and 8gb that would be great.

i currently am only using 4 gb.

Here ya go....

OK but, you really should be running MemTest first, after making changes to the RAM settings and then IBT Stress Test in Windows after your memory passes. Once your changes pass both tests then, try your game out.

vF-ePiC

game still crashes all the time. Gonna run memtest.

Sounds good....and looks like we'll have to do some fine-tuning.

Run it for 20 passes at Standard Level. If that passes then, run again at Max Level. Be sure to keep a close eye on your temps.

It is possible that your game crashes could be attributed to your GFX card. We need to get your system stable with the OC before worrying about that.

What were your temps like running IBT at max??
