Please log in for more thread options These motherboard has 4 empty memory slots: Channel A, DIMM 0 Channel A, DIMM 1 Channel B, DIMM 0 Channel B, DIMM 1 If I have 1GB at Channel A, DIMM 0, I can run both XP and Vista (32 bits Ultimate and Business) fine. I am unable to run XP at 2GB stable. When I run the defragmenter, I will get blue screen crashed promptly. I can run Vista (32 bits ultimate) at 2GB stable only when I have: Channel A, DIMM 0 has 1GB Channel B, DIMM 0 has 1GB. but, it does has blue screen crash about once every other weeks. I am unable to run Vista (32 bits) at 2GB when I have: Channel A, DIMM 0 has 1GB Channel A, DIMM 1 has 1GB. I run the defragmenter and Vista will crash in blue screen. So, what is the correct slot for 2GB? Is 2GB works on XP and Vista? | ||||||||||||||||

Please log in for more thread options First, get a memory testing tool. You don't want to be trashing your OS for this. A memory test tool should boot from a floppy or CDROM, and just test the memory. http://www.memtest.org/ (memtest86+) http://oca.microsoft.com/en/windiag.asp Insert the memory, one stick at a time, and verify it. There is no point trying two sticks, until each stick has been tested separately. (Your motherboard manual contains a note, about which DIMM slot to use first, like if you only have one stick of memory.) The memtest86+ tester, will run in a loop, all night long if you want. When you quit the program, the computer will reboot, so you want to remove the floppy before it gets there a second time. I recommend two complete passes (about two hours or less), as enough testing. Memtest86+ is not good enough to find all possible problems, but it is a start. A program you can run in Windows, is Orthos. This also tests memory and the CPU, and hopefully this will do less damage than a busted defragmenter would cause. This will stop when the first error is detected. http://sp2004.fre3.com/beta/beta2.htm If one of the sticks is bad, replace it. Another thing to consider, is the BIOS settings for the RAM. Many motherboards, default to "Auto" when you get them from the factory. Auto will read the SPD EEPROM on the DIMM, and set the timings based on the information in there. If the memory product you bought has a web page with timing info included, you can use the following program to read out the timing numbers and clock frequencies, with this. http://www.cpuid.com/cpuz.php Click the "Memory" tab. The "Frequency" should be multiplied by 2, to get your "DDR" rating. The four timing numbers, might be something like 5-5-5-15. Check your Intel BIOS screens, and see if there is a setting for DIMM voltage. If the memory is DDR2 type, the nominal voltage for it is 1.8V. Some memory products, state that their timing won't be met, unless some elevated voltage is used, like 2.0V. If the BIOS has a setting for the voltage used to power the memory DIMMs, you might increase it a bit. (Check the memory maker's specs, for any expected or max values for voltage, and adjust according to those limits.) For example, my DDR type memory is nominal 2.5V and I run it at 2.7V since I've had my system. The BIOS release notes for your board are extensive, but I don't see anything in there to suggest a BIOS upgrade is needed. http://downloadmirror.intel.com/14656/ENG/MQ_1709_ReleaseNotes.pdf Paul | ||||||||||||||||
