Hi,

I just got my new RAM today so i put it in (16 gb 4x4gb sticks 1600Mhz 9-9-9-24 1,5V)
And when i put it in it wont boot :( . It only tries booting over and over.
My old ram is 2gb 2 sticks of 1 gb 1066Mhz.
I tried to only put 1, 2 and 3 in put that wont boot either.
i hope you guys can help me out here.

Motherboard: Asus M4A785TD-V EVO

Thanks in advance,
Dustwellow

is new the RAM you got on the QVL for that motherboard?
did you try running it at 1333 instead of 1600?

uhm whats QVL?
and how can i do that ? running on 1333 instead of 1600?
Btw my processor is AMD Athlon II x4 630 2.8GHZ

QVL is qualified vendors list, for motherboards there's usually a QVL for CPU and one for RAM. the QVL lists all the specific sticks of RAM that Asus has verified works with that motherboard. if your new RAM is not on the QVL then that may be the problem (RAM not on the QVL will typically still work anyways).

the other thing i see is various RAM clocks: your new RAM is 1600Hz, your old RAM was 1066, and your motherboard supports up to 1333, or 1600 in O.C. mode.
you need to go into the BIOS and tinker with RAM timings. try 1600(800) first, if it's not stable then try 1333(667). i suspect the motherboard is still on 1066(533) and the new RAM doesn't like that.

while you're in the BIOS it wouldn't hurt to verify the RAM voltage is at 1.5 as well.

The QVL is the "qualified vendor list" it's a list of the memory the motherboard supports or lists as compatible, I went and got the link for you hopefully this link makes it through :D 

DL/open the list and see if your memory modules are listed on it

no! forcing 1333 or 1600 on your old 1066 RAM will not end well.
put in one stick of your new RAM, enter BIOS (usually DEL on Asus boards), find RAM timings, change it to 1600(800). if that doesn't work then try 1333(667).

uhm i tried the forcing thing xd but, i cant get it started with 1 stick too :(

well, you could chance trying to change the timing using your old RAM, but i would highly NOT recommend that.

do you have any other DDR3 sticks that you could use a go-between to change the timings?
using your old RAM, can you verify the mobo is sending the RAM 1.5V?
have you checked if your new RAM on the QVL yet?

First, what EXACT 4x4GB set(s) are purchased? Please provide a link.

Next, there are (2) possible CPU's:
ADX630WFK42GI - BIOS 0203
ADX630WFK42GM - BIOS 0506

IMO with 4GB/stick density the OLDER BIOS simply would do what you're experiencing now {BSOD and/or Post Failures} therefore update your BIOS using the old RAM -> M4A785TD-V EVO BIOS 2005 - 2105 -> http://usa.asus.com/Motherboards/AMD_AM3/M4A785TDV_EVO/...

Use the ASUS EZ Flash 2 method + FAT-32 bootable USB 2.0 Flash Drive.

While QVL is fine it's not the end all be all list, and I know your Athlon II x4 630 can run DDR3 1600 MHz although maybe DDR3 1333 with 16GB is a better option, the Default is DDR3 1333 MHz. http://img232.imageshack.us/img232/8128/cpuzx.jpg

With the 4x4GB installed use the Jumper Method -> Clear CMOS as described in your manual. Again, please provide link(s) to your RAM.

Recap:
1. Update BIOS
2. Clear CMOS
3. Post links to your RAM

Hi,

have you tried a clear cmos ?

true. but it gives a pretty good indication what what size/timings/voltages will work. if a QVL says brand X's 1600MHz 4GB sticks work then that makes me 99% confident brand Y's 1600MHz 4GB sticks will also work even if not on list.

EDIT: i just checks out the QVL for his mobo and there is not any 4GB stick on it. (gotta wonder how Asus claims max 16GB without a single 4GB stick on the QVL)

THANK YOU SO MUCH GUYS!

jaquith you are a GOD to me now the bios update worked :) )))))))
thx so much also branden thx for all the effort you put into it i really appreciate the help that is give n on these forums!

The CML16GX3M4A1600C9B 'should' work, I know CMP16GX3M4A1600C9 will work.

@branden - I've had QVL found to be incompatible and had ASUS, Gigabyte, & MSI update their 'Certified' lists. You should be able to install ANY 'SPD' DDR3 1333 MHz unbuffrerd 1.50v and it should work. AMD IMC is a lot more 'touchy' and BIOS updates for 'Improved Stability and Memory support' are often for 4GB/stick density support.

If after both BIOS update & Clear CMOS and you still have a failure:
BIOS **:
Memory OverVoltage -> +0.05v~+0.10v or 1.55v~1.60v
Memory Clock Mode -> Manual
Memory Clock Value -> 533 MHz ; successful boot -> 667 MHz {533 x 2 = 1066 and 667 x 2 = 1333 MHz}

** IF you cannot post or get in BIOS with NEW RAM then install the old, boot into BIOS make the BIOS tweak, shutdown, re-install NEW RAM, cross fingers and push the Power Button to start.

Glad to hear! :) 

I was typing a bunch of stuff -- just in case -- then I saw the success!!! COOL :sol:

Your motherboard shows memory specs of:

4 x DIMM, Max. 16 GB, DDR3 1800(O.C.)*/1600(O.C.)/1333/1066/800 ECC,Non-ECC,Un-buffered Memory
Dual Channel memory architecture
*AMD AM3 100 and 200 series CPU support up to DDR3 1066MHz
**Due to OS limitation, when installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Install a 64-bit WindowsWindows® OS when you want to install 4GB or more memory on the motherboard.

You would need to put in 2 or 4 sticks and then get it up and running. I would also make sure that if you flipped the memory voltage to 1.65 if that allows it to boot instead of 1.5. I have a set that says it will run at 1600 with 1.5 volts but it doesn't.

I would think the ram speeds you are doing will work out fine with your motherboard.

After this it's down hill. However, IMO if you're upgrading your OS then it's 'best' to do a 'Clean Install.'

Good Luck! :)
