    similarly, i can say winbond doesn't mean it'll scale well.

    only winbond makes that kinda chips, as far as i know (look at the 2 on each side metal contacts too). do you have pictures of the promos chips?

    haha, these are confirm chop chop WI UTT, no doubt
    results tell everything.

    1 of the best UTTs i have tried so far, thou didnt whack to the fullest, but at least doing 250 2-2-2-5 @ 3.3V only, the rest required like 3.4-3.5V.

    yep only winbond makes such chips, easily recognisable (dimples + 2-on-each-side metal contacts). so all the above are winbond

    well, follow the lower performance 1 lor, should scale around 260-270 @ 3-4-4-8 for 256mb, or 250-260 for 512mb.

    What does Lifetime Warranty mean for RAM
    When a certain model of the RAM are phased out or discontinued, rma old ram such as SDRAM or EDO DRAM are still possible provided they still have stock . If no stock left, then can kiss goodbye to Lifetime Warranty too.

    Value ram which use Winbond chip or Brainpower PCB are a steal!
