Memory Activity LEDs

Posted by CmdrTaco on from the pimping-out-your-puter dept.

Azert writes "Since a few months almost every popular memory maker includes heatspreaders with their fastest memory modules. Probably Corsair is setting a new fashion with their new line of memory with memory activity LEDs XMS ProSeries modules feature a row of LED's on the top edge that display real-time memory activity level. Each memory bank has a row of nine dedicated activity LED's that alight as the level of memory activity increases. 512 Mbyte XMS ProSeries modules, with two banks, have a total of 18 activity LED's in green, yellow and red."

  1. New Optical Tempest issues? by teqo · · Score: 5, Interesting

    Now, will case modders with transparent cases have to face a new optical tempest problem (beware, PDF link!)? (People being able to sniff potentially critical data through analyzing LED blinking, that is...)

  2. Encouraging emi/rfi? by v1 · · Score: 5, Interesting

    With all the case modding going on, I wonder how much though has been put into the interferance being generated by all the clear cases that are around today? There's a reason computer cases normally come as a solid sheet of metal. It's called a "faraday cage", (sp?) and is used to keep the nasty interferance generated by today's high speed systems inside the case.

    Most stock case systems come complete with rows of metal "fingers" along the edges where sheets meet, and where the ports mesh against the back of the case, etc., to keep emi/rfi from leaking out. I'm assuming all of this bother is to keep the case within FCC regulations for generating interferance.

    I wonder just how much interferance a typical "clear case" system generates to the surrounding area? Has anyone here at /. ran across any studies or sampling done on computer-generated interferance?

    Pin 39 on the IDE bus is activity. Wire an LED to that.

  4. LED's to indicate bad RAM by forevermore · · Score: 5, Interesting

    Activity lights are nothing. Relatively useless in the grand scheme of things (except they'd make a wonderful addition to a good case mod)... The new Intel Blade Servers (sorry, no link, they're not released until Tuesday - you might try searching for the IBM ones, since they're pretty much the same hardware) have an LED next to each RAM slot that lights up when the stick dies (there's a capacitor on the board that keeps 30-40 seconds worth of electricity, so the LED's will stay lit up when you remove the blades from the chassis).
