    Default GA-EP45-UD3R Mobo BSOD with OCZ2RPR10664GK RAM

    I've got a computer I just built and loaded vista on.

    700 Watt thermaltake PSU
    E7400 core 2 duo
    2x2GB sticks of OCZ2RPR10664GK ram
    ATI 4870 vid card
    GA-EP45-UD3R Mobo
    2x150gb

    It gives me a BSOD error (irq not less or equal) the moment
    I try to open a web browser (be it fire fox or IE). Other than
    that I haven't gotten a BSOD before that, but I haven't played around
    on it all that much. I have seen other postings
    of people having trouble getting the OCZ ram to be fully stable with
    this mobo though. So here are the settings in my BIOS for this.

    Firstly set your PCI Express Frequency (Mhz) .........:100
    I also just did a quick google and it may be that that ram needs a tad more volts. Try bring it to 2.3v and see what happens. I do think that your BSOD are RAM related and Running Memtest 86+ V2.11 will show you this no doubt if you run it through several passes. I would do that to confim that it is indeed ram.

    When you say it's ram related do you mean that the ram is bad? Or just that it isn't stable with this mobo? Also I changed the voltage to 2.3 and the PCI frequency to 100, and no change. Still BSOD. I'm about to start running the memtest86+.

    My setup is very similar to yours, except with q6600. First, you should lower tRFC to 56, which is recommended by OCZ. That cured a BSOD prob I was having. Then, you might lower MCH to 1.2 or back down to 1.1. You might also, lower your DRAM voltage to 2.0, also recommended by OCZ, and run memtest.

    Tried all that you said (voltage to 2.0, mch to 1.2, and trfc to 56) and no change. Running memtest right now, almost done with first pass and no errors. I'll let it go through a good 10-20 times.

    Well its good that you have done 7 passes with no errors. It may be more sinister. When I say ram related it could mean bad ram or bad settings not perfectly stable, but Memtest should have come accross this. This is were it gets a little more tricky. Might have to start swapping out other hardware. It wouldnt hurt to run seatools on your HDD's either but Im not so sure. Do you have other ram & Video card to try. even if its old slow crap DDR2 just bash a stick in and see
