    Darn and I was hoping I could crank 20v into them and not have to worry about them dying
    Fast computers breed slow, lazy programmers
    The price of reliability is the pursuit of the utmost simplicity. It is a price which the very rich find most hard to pay.

    Fatty D9 dies just as fast....voltage shows no mercy

    Infact its not the voltage that kills it, you need the increase in voltage to get the memory switching faster, but a by product is more heat and an increase in current used. The increase in current is what kills it as its quite easy to control the heat.

    Micron is mad expensive again at this time, if you want to keep it working reduce the vdimm
    Got a problem with your OCZ product....?

    I have found that the modules will sometimes overheat and stop working with high VDimm. People often assume the RAM is dead. In some cases, but not all, taking the modules out of the board and letting them cool off will solve the problem.

    by testing my Kingston PC 4200 between 3.3v and 3.6v during approximately 5 hours, I saw well that 4 chips D9DCD were affected by the voltages, the ram functions but it is necessary for more volts to him so that it starts correctly (2.6 / 2.7v instead of 1.8v of origin)

    I would not test with the other kits out of PC 8500 which I currently have, I dont want of to damage even more the chips in D9GKX which are absolutely not the same price as D9DCD

    Fatty D9 is 90nm whereas the newer stuff is 80nm so like with cpu's wouldn't the voltage hurt the Newer ones more atleast a little bit? So fatties do take a bit more voltage? jw

    in theory, yes. in practice? who knows
    Got a fan over those memory sticks? No? Well get to it before you kill them
