| >>> Comp. All new components
Mobo
ASUS Crosshair V Formula
0903 BIOS (newest one on the asus sight but there are other newer builds floating around)
PSU
Antec High Current Pro HCP-750 750W
CPU
AMD Phenom II X4 980 Black Edition Deneb 3.7GHz
RAM
2 x G.SKILL Ripjaws Series 8GB (2 x 4GB) DDR3 SDRAM DDR3 1600 Model F3-12800CL9D-8GBRL
HD
Corsair Force Series GT 180GB SATA III Internal Solid State Drive (SSD)

System wasn't stable, did the following.
Changed the following in bios.
RAM frequency to 1600.
DRAM Command Rate 2T
RAM timing to 9-9-9-24
Read to Read timing 5
DRAM command rate 5
CPU/NB Voltage 1.2
DRAM voltage 1.5
CPU-NB frequency 2400MHz
Now on boot 1 of 3 things happens;
System detects 16 gigs and is compleatly stable (wooo). (10%)
System detects 16 gigs and only 7.96 are usable. (50%)
System detects 16 gigs and system locks up in 2-7 minutes. (40%)
Any other ideas what to do?
My current plan is to flash CMOS put these values in again.

Greg,
Welcome to the forum. I am not real sure I got this right you are saying your memory volts are set to1.2 volts? I think it should be more like 2.1 volts. Check with G.Skill to be sure.
If you wish, at login, go to edit my profile (top left),click on signiture,type in your system set up and it will always show in blue on bottom of your post( this will help you and others to get more accurate info). Cheers.

I don't know if it is a typo but after the read to read timing which (incidentally should be 4) you have Dram command rate 5 which is impossible the only options are Auto, 1T or 2T, the CPU/NB voltage is OK but the ram Voltage isn't you will need 1.65v for an AMD system, put the CPU/NB frequency back to 2000Mhz it's pointless increasing it when you are not stable. You seem to be using 2 separate 8 gig kits and not a quad kit so it's possible to get a mismatch not that it is likely, I haven't had problems using 2 kits in the past. Before trying to use 2 kits see if it is stable just using 1 then if it's OK try the other kit and go from there. I have 3 systems running 16 gig of G.Skill Ripjaws ram, 1600Mhz, 2000Mhz and this one 2133Mhz, also 1 with 8 gig at 1600Mhz. Check this link there is a memory setup guide there and also an ASUS support guy.

Incidentally there is a BIOS ver. 9921 which mainly fixes problems with Steam games not working on the Bulldozer, it's not really a BIOS for the Thuban chips .
CVF beta UEFI 9921
Latest AGESA update for Bulldozer from AMD in this build:
More enhancements for Steam games etc.

Just close the advert if you get it the download is behind it.
