Hi I have been observing a weird problem with my new mobo. I have 8G of PNY DDR3 1333MHz RAM (4x2G). When I put all the sticks into the mobo, and run tests using memtest86/86+ and other memory tests from the UltimateBootCD for more than 24 hours without a single problem. I also used Windows Memory test Tools with the same result - clean. However, when I run windows, I get blue screens with MEMORY_MANAGEMENT problem being reported all the time. I used also MemTest from http://hcidesign.com/memtest/support.html, which generates plenty of read/write errors under windows. I am very much confused so to what can be the potential problem of an error. I run Ortho stress test. CPU only tests are clean after 5+ hours of testing. RAM only tests are clear after 5+ hours. When I try a BLEND type test, I get error within 10 seconds from the start. Memory runs at nominal timings, (9/9/9/24) with upped voltage (1.6V versus 1.5 in automode). Any suggestions on what I should be looking at ? Thanks Marek

full system spec please, and are you overclocking? It's common in a lot of motherboards need a small voltage bump to the NB when all slots are populated.
System: Windows 7 x64 Mobo: GA-P55A-UD4P Memory: 4x2G PNY DDR3 1333MHz, running 1333MHz at 9/9/9/20 (stock timing) at 1.6V (stock voltage) HDD: 1TB Caviar Black GPU: PNY GF460
CPU & memory running stock voltage and automatic settings
So you set the ram to it's rated voltage and main timings? If not give that a try, if still no joy, you can safely add .5 volts to the memory as long as you stay under 1.65.
Correct, however, I tested the voltage range between 1.3 and 1.67 V already and it does not seem to impact the observed instability problems. I tested voltage range between 1.3 and 1.67V, with memory clock between 800 and 1333 MHz. I could not find a single combination that would work in a stable manner. The best part of it is there is no memory corruption using Memtest86/86+ tools without running Windows ...
If you set the proper voltage and timings and your not overclocking, it might be time to start testing the modals for defects. It's a pain in the arse but I would test each stick individually. You might have a bad stick or two, can't hurt to try. And just to clarify, all other settings are default or auto correct?
I spent already 2 weeks testing them one by one. Same result. No errors shown in Memtest86/86+, errors and blue-screens when running Windows. I am out of ideas. If nothing else can be done, I will return memory sticks today and replace with a different brand. Sick of PNY
Just did something really stupid: disabled the CPU EIST / C1E / C3/6/7. memory is stable under Windows. Any explanation for that ??????
Sorry, no such option in my BIOS Now testing whether 8G will work fine with this configuration, 4G seems to have no problems passing burn in tests. Will let it run for 1 hour and come back with any feedback Thanks for the time
No MCH/ICH setting? Should be under advanced voltage settings
Thanks. Found it (was in strange greenish colour and not really visible). It turns out that 3 banks out of 4 have errors. Only one is stable. Will return the memory tomorrow and ask for a different brand. Thank you for your time
