A7N8E-Delux with TWIN1024-3200C2


Recommended Posts



I have just bought all my conponents couple days ago. Before I started to setup my PC, I almost read all the posts here. I followed BIOS setting as RAM Guy suggested. When I try to install windows XP on it, it easily gives me a blue screen. The error message usually will be "IRQL_NOT_LESS_OR_EQUAL" or "PAGE_FAULT_IN_NONPAGED_AREA" or sometime the installation will stop at last step "configrating system ....", anyone can help? please.


btw, I use memtest to test memory. I left the pc running overnight. (about 7 hours) The report shows total 6 errors, all of them are on Test6. I wonder if it is memory problem.

Please maken that you set the jumper setting from the default 1-2 to 2-3; in addition please make sure that you have the latest BIOS for your MB and load Setup/Optimized default settings, and try the following BIOS settings;

TwinX1024 or TwinX512-3200C2

CPU Freq: 200 MHz (400 FSB)

System Performance: User Define

Memory Frequency: 100%

Resulting Frequency: 200 MHz (400 FSB)

Memory Timing: User Define

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 6T

DDR Reference Voltage: 2.7 Volts

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

All other settings are motherboards defaults

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!

Hi RAM Guy,


I did everything you mentioned. I tested one stick each time. memtest86 didn't report any error. But after that I tested with 2 sticks (on dimm2 and dimm3). I kept the machine running overnight, total 21 passes (not finish on the 21st pass). and I found 6 errors


the reports looks like


Tst Pass Address Bad ErrBits Count

6 3 1019.7MB ffffff00 000000ff 1

6 9 479.1MB ffffff00 000000ff 1

6 14 443.8MB ffffff00 000000ff 1

6 17 427.4MB ffffff00 000000ff 1

6 19 431.3MB ffffff00 000000ff 1

6 20 379.3MB ffffff00 000000ff 1


Could you help me on this case, I guess the memory is good, but some setting s on my machine maybe wrong.

Thanks Ram Guy, that is really good, set the ram volt to 2.8 works. I ran the memtest overnight again last night, no one error appears this morning during the 20 passes. and my xp works very smooth now. Thanks again. You saved me.


Fido :laughing:
