8gb Ram freezing bios

Hello thanks for looking hope you can help me out!

cpu
i5 655k

Mobo
GA-H55-USB3

RAM
G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL10D-16GBXL

Put my new RAM in with a new 2 port sata 6gb's pci express card and my SSD

My machine booted, went to bios, I entered the setting to make sure the speed for the new RAM was correct, it was set to 1333 so I bumped it up to 1600 rebooted and then my machine started to freeze at the bios and boot loop.

I tried clearing the cmos, trying one sick at a tme in each slot, upgrading the bios through @bios, I just read the threaed that I'm never suppose to do it through that but I've done tons of times at least three times alone in the frustartion of trying to get my rig to run this current RAM. If you think it might be that I can update my bios another method.

Desktop will boot if I replace it with my orginal 2GB Dimms

Any tips, advice, or other trouble shooting would be awesome!
Thank you, I'll check back at this thread around 4 or 5 oclock!

Few things besides 8GB/stick isn't officially supported, NEVER flash your BIOS with anything except Q-Flash, simply setting your Memory Multiplier will fail in most instances, and lastly in order to run DDR3-1600 w/o a BCLK OC you need a 2.66GHz CPU (which you have).

So if you can successively boot with the '2GB' RAM then update or re-flash the BIOS:
Nice 3-part video:

2. http://www.youtube.com/watch?v=Qlx5GBkiaM0
3. http://www.youtube.com/watch?v=EX78S4qyHu0

Next if you can boot with the 2x8GB I'd leave it. However, if you want to play dice then the following:

Kit:
F3-12800CL10D-16GBXL DDR3-1600 10-10-10-30-2N @ 1.50v

DIMM slots:
CPU: | blank | 8GB | blank | 8GB | ; use White

BIOS:
/note: by default after a Clear CMOS or BIOS update all info will be erased/
/note: if the SATA (WAS) -> AHCI change it to whatever it was before the 'RAM'
Load Optimized Defaults -> Yes
Advanced Memory Settings /Enter
Extreme Memory Profile (X.M.P.) -> Disabled ; I'd avoid using XMP
System Memory Multiplier -> 12 ; 133.33 * 12 = 1600
DRAM Timing Selectable -> Quick
CAS Latency Time -> 10
tRCD -> 10
tRP -> 10
tRAS -> 30
Command Rate (CMD) -> 2
QPI/Vtt Voltage -> 1.25v~1.30v ; start high
DRAM Voltage -> 1.50v~1.55v ; start high

(F10) Save & Exit = Yes

/note: the volates I posted are all safe and IF attempting DDR3-1600 with 8GB/stick density RAM then you need the +0.05v for stability.

IF it posts successfully then run Memtest86+ - http://www.memtest.org/#downiso overnight; no errors your home free enjoy, errors up the QPI/Vtt Voltage -> 1.35v (edit/ DRAM Voltage -> 1.60v) and test again.

Good Luck! :)

Awesome! Thanks for the advice, Wish I would of read earlier never to use the @bios, hoping this is the fix! I'll check back in an hour or so hopefully on my new rig =]

System boots with 16gb ram, with slots 1 and 3 can not boot into OS on orginal working hard drive or a usb drive, the system loads and get to the start windows screen(windows 7) and then just hangs there with no animation.
When I run memtest it runs for less then 5 minutes and then the PC reboots, admittedly I don't have anywork with memtest but I wouldn't guess that its suppose to do that. I will continue to try different settings.

The Memtest 'reboot' shows the system is unstable. Use higher voltages.

Q - What exact RAM BIOS settings did you use from the info above?

Just loaded optimized defaults and tried booting into the OS and memtest, will start tweaking the voltages now, I had just loaded the optimized defaults which had the QPI/Vtt at 1.1 and the DRAM at 1.5,
currently trying new voltages you've suggested mobo only offers voltages in .02 jumps...
DRAM is 1.56
QPI/Vtt is 1.29
Giving a reboot now and will change voltages if unstable

Is there a voltage I should stop at?
Currently
QPI/vtt is 1.30
DRAM is 1.6

bumping it up by .2 every reboot
memtest freezes at 2 seconds every time, test gets to variable percentages every time but freezes and reboots none the less

Stopping at
QPI/Vtt at 1.55
DRAM at 1.8

Settings
XMP - disabled
system memory multiplier is set to 12
performance enhance is standard
DRAM timing is quick
cas latency time is 10
tRCD 10
tRP 10
tRAS 30
all advanced timing is auto
execpt for CMD is at 2

Do yuou think I should keep bumping up the voltage? or maybe there is a problem with my memtest, the test stops running after two seconds with variable percentage complete, but there is a cursor blinking under L3 and the red plus after memtest title blinks, after about 30-60 seconds my system reboots

Voltage bump = No. Those are too high now.

If you can run at DDR3-1333 then be happy, you can use the initial set I posted and change System Memory Multiplier -> 10 ; 133.33 * 10 = 1333.

Never did get it to run a full mem test, I'm just going to go the way of upgrading my mother board to bad I have an 1156 Socket cpu having a hard time find a cheap motherboard to upgrade it to. Thanks for all the help thought none the less
