ASUS P6T-Deluxe v2 strange RAM_not_detected_problem solved by chance
Here is a curious story.
The mobo is an ASUS P6T-Deluxe v2 with an i7_920 processor and 3x 2GB oF RAM running at 1,6GHz. Over the past 4 years, a strange problem had occured that has also been described by others: When starting the computer "cold", all 6 GB of RAM were detected. When rebooting from a warm state, most of the time only 4 GB of RAM were detected. This led me to deactivate suspend-to-disk state. Only a week ago, i cloned my 1 TB hard-disk and replaced the HDD with a 2 TB one. Both HDDs are / were SATA 300, both were of the Seagate barracuda series, so nothing spectacular. But now ever since, the RAM_not_being_detected problem seems to have disappeared. No matter if i boot the machine warm or cold or reboot after many hours of operation, always the 6 GB of RAM are detected. Great! But i wonder if anyone has an explanation for this? Where is the connection between a HDD and the RAM? ;-) greetings from Vienna Roland Schweiger |

Had you tried removing and reinserting the RAM to solve the problem? -- Faster, cheaper, quieter than HS2 and built in 5 years; UKUltraspeed http://www.500kmh.com/ |

the RAM to seat properly. Had you tried removing and reinserting the RAM to solve the problem? Yes indeed, i did that a year ago ... took out all the RAMs and put them back in in different order, the problem remained at that time. greetings Roland Schweiger |

Seems to me then that it's just lucky magic :-) -- Faster, cheaper, quieter than HS2 and built in 5 years; UKUltraspeed http://www.500kmh.com/ |

Seems to me then that it's just lucky magic :-) hi. magic in computer science, wow :-) I vaguely remember a claim at one time, that adjusting some "voltage" in the BIOS, might change the RAM detection. And probably not VDIMM. It could be the voltage fed to the memory interface block (IMC). http://hardforum.com/archive/index.php/t-1546247.html "it seems that in this case it is more of issues of the vcore, qpi, and pll getting in sync" Certainly a bad socket could be causing the problem, but then there are people who have stuff work on one boot and not on the next boot. And I refuse to believe a gold on gold contact, with biting action, is going to do that. But maybe a marginal set of operating voltages might. It's also possible a BIOS update makes a difference to behavior (better AUTO choices baked into the BIOS). Paul |
