CMX8GX3M2A1333C9 and Asus P7P55D-E


Recommended Posts



I'm currently building the machine as in my profile for my dad.


Trying to get the memory kit to work on the Asus mainboard has been a real pain in the ***. So far, all my efforts failed. I've tried numerous combinations of speed, timings, voltages and so on. Using the XMP profile stored in the memory didnt work either.


Basically, when the 2 modules are installed, the system is very instable, up to bluescreens during the Windows installation (doesnt matter which version, WXP to W2K8 R2). When only one module is installed, the system is rock solid and I can throw anything against it, it does not go down and Windows 7 installs fine, including updates and Office etc etc.


Memtest86+ 4.10 doesnt detect any errors, ran it over 24 hours and roughly 20 passes.


Now i've noticed that the 2x4GB kit isnt in the memory configurator, yet the 4x2GB kit (CMX8GX3M4B1333C9) is. Can i conclude from this that my kit is basically never going to work with both modules installed? I have no need for overclocking purposes of some sort, I just want the machine to be stable for the next 3-4 years and possibly keep some memory upgrade options available.


Could anyone give me some advise on this matter?

Short update:



Took some memory home from work (working at the IT department certainly helps when troubleshooting).


3 modules from a Dell T3500 workstation (DDR3-1066 memory, Samsung) and 2 modules for a Dell Optiplex 780 (DDR3-1066 memory, Kingston). All 2GB in size.


Installed the 3 Samsung modules and one of the Kingston modules, actually by accident, didnt plan on mixing modules per channel. So theres now 8GB memory available in the system.


Booted, Windows Update, all fine. Furmark, fine, temps of the GPU didnt reach beyond 60 degrees Celcius. 3DMark Vantage Pro, 5 passes set. No errors.



Now, initial Corsair memory placed inside a Dell Optiplex 780 (not the same config as my original tho, its a C2D on a ICH10 memory controller so no CPU integrated memory controller. Don't have any i5/i7 rigs around either). Looks like this is running fine as well, at 1066Mhz bus speeds.



Can we safely conclude that the memory is incompatible with the motherboard I currently have or are there any other options???

Ok I'm mildly optimistic now.


Before returning the "defective" memory to the reseller tomorrow I thought I'd go over everything once more for good measure, including another reseat of the cpu while also applying new cooling compound.


After letting everything default, the system booted with the memory at 1067Mhz. CPU-Z reported this as well, and 3DMark Vantage actually was stable for a 50% run.


I then rebooted to the BIOS and set the memory speed to DDR3-1333Mhz. CPU-Z didnt like this at all and the system bluescreened on me (with yet another new BSOD for that matter, 0x01D).


I returned to the BIOS and loaded the XMP profile available in the memory. 1333Mhz, 1.6v RAM memory and 1.2v CMI.


The system is now running a double-pass 3DMark Vantage with about 2 hours to go (half hour into the benchmark) and its still without hickups or bluescreens.


Could it have been this "simple" as another reseat of the processor where 3 other attempts failed? Or could it have been that the cpu/socket/whatever had to go through some trial period like you would be driving the first 1000 miles in a car or something :/


I still can't get my head around it though ...



OK Nevermind all I said before in this post. The benchmark ran fine, when I wanted to reboot to set the BIOS back to AHCI and reinstall Windows, a new BSOD occurred. The memory is going back tomorrow. I'm done with it ... :(

Installed ******** ValueRAM CL9 10666 memory yesterday, 2x4GB. System is rocksolid after running a week without issues with the memory mix of Samsung and ******** memory at 1066Mhz.


IMO I can still safely say it was the memory that was just incompatible with the motherboard. Don't have any other ways of explaining it.
