Mayday! Beep Code Ram Compatibility??

I've built my own rigs for a decade now. I'm building this one for my nephew. Ive tried everything. I know I must use the DDR3 slots on the MB. This is a new build. Everything is new. I know its an older board but its new. My processor is a Dual Core 2.4G 775. If I pop in 4 gig stick of DDR2, everything works fine. If I put in 8g stick of the DDR3 linked below, in the DDR3 slot, 3 beeps on boot and no Display. Bios and all drivers are current. Is the 8g stick my issue? Should it be 4g? Thanks for any input.

The motherboard Im using is here:

The Ram that won't boot is here:

  1. That board only supports 4GB max ddr3 in two slots. You can only run one or the other.

    from Asrock:

    - Dual Channel DDR3/DDR2 memory technology*
    - 2 x DDR3 DIMM slots
    - Supports DDR3 1333/1066 non-ECC, un-buffered memory
    - Max. capacity: 8GB**
    - 4 x DDR2 DIMM slots
    - Supports DDR2 1066/800/667 non-ECC, un-buffered memory
    - Max. capacity: 16GB**

    *DDR3 and DDR2 are supported separately.
  2. Forgot to mention, Bios are loaded Default. Tons of Timimng options in bios, but I'm not familiar with RAM and BIOS settings. Voltage, Timing, etc...are all in AUTO. Wasn't sure if I should tweak any of these numbers....???

    Supports Dual Channel DDR3 1333/1066 (2 x DIMM slots) with max. capacity up to 8GB < You need 2 - 4 gb. modules
  4. You can run 4x4GB of DDR2 memory or 2x4Gb of DDR3 memory. Cannot run both types at the same time.

    And I would set optimized defaults then set up memory and what ever else needs setting up.
  5. Daggum!! Thats what I was afraid of, but figured I'd consult the community. You guys correct me if Im wrong, but the link I attached for the RAM, does it not say 8 gigs....2 x 4 gig sticks. Thats what I ordered but I have in my possession 2 x 8gig sticks......?
  6. Two 4GB sticks should be in the two green slots.
  7. makes perfect sense!! Anybody wanna make an offer on 16g G-Skill RAM....!!!
  8. Too bad I'M not building right now , i'd buy it , order the 4gb modules and you should be set.
  9. Brand New! :pfff: HA! Half price $$
    , you pay shipping....no joke!
  10. I just finished my HERO build a few weeks ago or I'd be paying for it right now.

    List it in the DEALS section.
