MSI X48 platinum will not post F3-10666CL8D-4GBRM

[M4fever]

MSI X48 PLATINUM (Not the C version. This one is DDR3 only) Core 2 duo E8600
This board will post and run well with the 2 sticks of 1GB memory I currently have. I am attempting to increase the memory to 4GB. F3-10666CL8D-4GBRM will not even post. I reset the Bios by unplugging the power, and depressing the CMOS reset button with no post. This board has a small dot matrix display on it that stops at DRAM. I selected this memory because this board is listed as compatible. any suggestions?

Do you have the latest BIOS? Did you set the timings and voltage up manually?

[M4fever]

Yes I have the latest bios 2.5 for this board. And yes I tried setting the timings and voltage manually. at 8 8 8 24 1.5v also tried slight increase in N bridge voltage. So far it won't post.

[M4fever]

I also tried some looser timings at 9 9 9 25 with same results.

Can you post your BIOS settings, so we can take a look

Make sure your memory divider is set to 1.6 to 1
The X48 Platinum has a hard time at 2:1 when using 4 sticks.
This makes your memory speed 1066 at 333 FSB.
I won't claim to have alot of tech knowledge, but I have had mine since fall '08.
Currently installed are 4 x 2GB Corsair Dominator 1600 but the only way to reach even 1333 is to overclock FSB. I'll try to re-check this thread, lots of luck...

some success at 1:1

Tradesman and arkoon, Thank you for your help.
So far I have only been able to get it to post at a 1:1 memory ratio! Tried all others without success.

Bios settings:

DOT CONTROL DISABLED
INTEL EIST DISABLED
FSB FREQ 333
CPU RATIO 10
FSB/MEM RATIO 1:2
PCI-E FREQ 100
PCI FREQ 33.3
MEMORY V 1.5
ALL OTHER V AUTO
SPREAD SPECT DISABLED
DRAM TIME BY SPD DISABLED

TIMINGS

CAS 9
RAS-CAS 9
RAS PRE 9
ACTIVE-PRE 27
TRFC 47
TWR 12
TWTR 12
TRRD 12
TRTP 12
1N/2N AUTO

If still unstable, may want to raise the DRAM and NB voltage slightly, prob no more than + .05 for either

Hey m4fever
I had problems with my X48 Plaitum(not C) with memory also.
I'm fairly techy but not like the guys helping you here.
I can offer you the settings I have found to work for my corsair:
You've figured out, probably, MSI itself says do not run mem divider at 2:1.
Mine doesn't care what I run it at as long as it isn't 2-1 with 4 modules.
I found the memory voltage wants more than even the 1.65v the corsair units are marked as.
Here is the short story, I hope it helps..
cpu voltage 1.275, lowest setting available for q9550
mem divider, 1.6:1
mem voltage 1.92, yes, 1.92- I have fsb of 378, runs q9550 @ 3.2 GHz
nb voltage lowest setting, 1.29, but I'm lucky there, you may ghave to go a notch higher
fsb term voltage 1.25 or 1.27, cant remember, don't want to reboot til you get back to thread
mem reference voltage .96

These mem voltages seem high but I had the same issues and even at 333FSB the system does not like to boot unless I set minimum 1.79v memory voltage
If the post LED says DRAM it likely is not CPU issue as you probably know- it is getting as far as the RAM.
You might try upping your mem volts while waiting for the techs here to respond
Just so you know I have rund mine as high as 2.0 mem volts, 1.0 mem ref, 1.38 NB adn 1.37 NB ref but that isn't what was the problem, it was mem divider and mem volts...
lots of luck
