Please use the ASUS Bios 1.013 or newer and then, please try these settings:

With the A7N8X-E please set the FSB jumper to pins 2-3 with the modules in slots 2-3 and then reset or clear the bios and load setup defaults and set the Dim Voltage to 2.7 Volts and set the timings manually. Then please test the system with http://www.memtest.org.

CPU Freq: 200 MHz

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Resulting Frequency: 200 MHz

Memory timings: By SPD

Would results in these settings

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 6T


If you get errors please test the modules one at a time to make sure one is not failing, I have had 4 of these exact MB's and this is what had to be done to solve problems with aggressive memory, no matters who's I tested. In addition, a few other's had some success disabling Spread Spectrum in the bios as well. I would take a look at http://www.asusforums.org as well in the AMD section.

ok, update, I have done eveything you said except for using memtest and i am not sure which slots are 2 and 3 for the RAM. It is labeled A1(middle) A2(closest to CPU) and B1 (Byitself near ATX power connector). can you please be more specific with the slots names?




PS am already impressed with system performance so far.

ok, after some investigation i discovered that a2 is slot (closest to cpu) a1 is slot 2(middle) and b1 is slot 3. I have changed RAM slots to coincide with what you have instructed (2and3). And I also ran memtest without any errors ;o) so as far as i can tell those games should be much smoother now hehe




PS the fix u have suggested is also listed in the forum link u posted for asusforums. and no complaints since its been posted hehehe

everything was running fine until the last few days, i am now getting the BSOD. After decoding and posting my mindump this is the answer i have received;


All of your minidumps are crashed with memory access fault. The culprit is faulty memory. You can run memtest to stress the ram. If memtest reports the ram is faulty, ram is bad. However Memtest is not a perfect tool to test the memory as some faulty ram can pass memtest.


My problem is memtest doesnt report any errors as above, i ran it again and no errors. Any suggestions?


I think I am going to remove one of the sticks. WIll this RAM run one stick alone on this board? If so, what config should I use please?

I have no problem replacing the modules if you want to try that! But I would suspect some other issue from what you have posted. Did you set the CPU_FSB Jumper? And can you tell me the complete system configuration?
