RAM is Being Physically Damaged Over & Over Again.
My current computer problem is as follows. I have a Pentium 4 processor at 2.4 GHz currently running one gig of RAM (Patriot). I have replaced computer case, power supply and video card. I have returned the motherboard five times in the past four months due to the fact that every time I get the replacement motherboard and install it and to the new computer case and turn it on within the first five to six hours of operation it cooks the RAM. or better words destroys RAM. This has happened six times & nobody can tell me what's wrong or what is causing this problem, I Hope someone out there can help? Or at least lead me in the right direction as to what is wrong and what I need to do to solve this problem. The motherboard I am using is an ASUS P4P800SE socket 478. & a SoundBlaster live 24 bit sound card & a promise ultra ATA / 133 (TX2) IDE Controller so that I can have up to eight IDE devices. Four on the motherboard and four on the IDE Controller card. This is for my Brother, i Have asked him for More Detail's on the Hardware & More Detail's on What Happened & When? The End result's have Been His RAM is Being Physically Damaged Over & Over Again. |

I'd suspect that the power supply is to blame. Sounds like it is giving
too much voltage somewhere. -- "Outback" Jon - KC2BNE AMD Opteron 146 ) and 6.1 GHz of other AMD power... http://folding.stanford.edu - got folding? Team 48435 2006 ZG1000A Concours "Blueline" COG# 7385 CDA# 0157 1980 CB750F SuperSport "CoolerKing" |

Is the RAM being verified in another computer, after the failure ? Does the motherboard also fail at this point, or can you plug more RAM in it and get another six hours from it ? Also, are the named PCI cards always present when it happens ? It sounds like you've replaced virtually everything, and then stuck the same two PCI cards into the system. Perhaps it has something to do with the PCI cards. Try your next test, without the PCI cards present. Also, has the computer case been inspected for its standoffs ? A brass standoff should only be installed, where there is a matching tin-plated hole in the motherboard. Make sure any standoffs that don't line up with a plated hole on the motherboard, have been unscrewed and removed. Standoffs have been known to short to traces on the bottom of the motherboard. A minimal test config would be motherboard, CPU, video card, RAM, and floppy drive. Connect the monitor, then boot the system with a memtest86+ floppy from memtest.org . See how long it lasts with that config (and no PCI cards). In terms of voltages, the power supply has its output rails, but a significant part of the motherboard is powered by regulator circuits located on the motherboard. So at least some things are isolated from power supply problems. But if one rail is bridged to another, there is little some of these regulator circuits can do about that. Many of the regulators are designed to "push" but not "pull". If a higher voltage rail is bridged to a lower voltage rail, the regulator may not say a word. Motherboard regulators are not protected against overvoltage/undervoltage. In fact, some of the Asus motherboard regulators consist of an opamp and a pass transistor, and they use components like that, because they are cheaper than using a proper regulator chip that will shutdown when there is a problem. I would look at the edge connector of the two PCI cards, and see if any of the pins are burned or discolored. The flow of current might not be enough, to leave a trace, but you can have a look anyway. You might get lucky.

RAM is Being Physically Damaged Over & Over Again.
With that many drives in the system, it is VERY possible that if he is not
using a HIGH QUALITY, HIGH POWER output power supply that the RAM is being fried when the power supply tries to supply enough current to drive all those harddrives. An inexpensive and/or underpowered PSU will become VERY unstable in its voltage and current output if stressed overly and will ruin delicate components like RAM. -- DaveW ---------------- "Joe Near Portland, OR.
