Memory managment error BSOD

[holopainen]

Hi,
I have to modules of 2gb Kingston 1600 mhz rams (FLGE85F-B8MF7)

My gigabyte ga-ma790fxt-ud5p mobo recognizes it as 1333 mhz. I manually set it to 1600 mhz in the bios. It seemed stable, but at a reboot later, it presented a BSOD with memory management error message. It was also a reboot because I tried to install an old webcam in compatibility mode, I'm not sure if it's connected. Should I set it back to 1333 default?

Thanks in advance.

Hello, I'm Jewel with Kingston Technical Support and would like to offer our assistance. Short answer, yes, I would suggest to change the memory settings back to the defaults for stability. The memory part number you indicated is not a proper Kingston part number, I did find it online as a 'Kingmax' brand module. At any rate, your motherboard GA-MA790FXT-UD5P supports the memory speed 1333MHz stable and 1600MHz overclocking. Depending on what your processor supports, most systems will run memory at the fastest stable speed or the default memory speed the module is programmed. It is likely that your processor only supports up to 1333MHz which would explain why it defaulted to 1333MHz. Or you may need to change the DRAM timings to what the module is rated for and it would be best to contact the manufacturer of the modules to get that information.

Yes it's Kingmax. Thank you very much for the detailed answer.

ANY DRAM when first installed goes to the mobos default freq (generally 1333 or 1066 on AMD), you have to set the sticks up on AMD mobos (to include freq, timings, voltage and oft times the CR), big thing here is if your CPU can carry the sticks - for 1600 chances are good if you have a 965 C3 or better CPU - so what CPU do you have and we may be able to get htem running at 1600

HI, I have a phenom II 955be running at 3.4 ghz, with only the multiplier modified.

Memory is set to 1333 mhz currently:

To try for 1600, try the following

1. Set DRAM Frequency to DDR3-1333.

2. Set CPU Host/Bus Frequency to 240 (this will overclock the memory frequency to DDR3-1600)

2a. Raising the bus frequency will also overclock the CPU, so if you do not want this, you will need to lower CPU Ratio to your desired frequency. If you do want to keep it, you may need to raise CPU VCore to stabilize the overclock. If you have a Black Edition CPU, then it should be capable of the overclock without any voltage adjustments, but for non-BE's most likely you will need to raise CPU VCore.

3. Set timings to tCL 9 - tRCD 9 - tRP 9 - tRAS 24, or whatever your memory is rated for.

4. Set DRAM Voltage to 1.50V, or whatever your memory is rated for.

5. Most CPUs will need a CPU-NB Voltage boost of +0.10V, so if your default is 1.10V, set it to 1.20V.

and let me know
