    CPU Multiplier problems

    In the computer in my sig, I'm having a problem with setting the multiplier. I can set it down from the stock 9, but not up. The selections are there in the bios for up to 19x, and I can select them. It will even show the correctly calculated number on the screen at POST, and in Windows. But, in CPU-Z it shows 9x and the appropriate number of MHz for a 9x multiplier and whatever bus speed I'm running. Also, my super-pi times do not improve. Plus, being able to set 19x400 and have it boot into windows kind of tells me it's not really setting it.

    I am using the latest Rebel's Haven mod bios, although I have tested it with a couple standard Biostar bios's with the same results.

    I can still OC using the bus speed, and I'm currently running 445x9 @ 1.34v. But I want my multipliers dammit! I paid enough money for the QX chip I should be able to use it.

    After you all stop laughing, got any ideas?

    You can't with Intel.

    But, I heard that multiplier increasing is possible with the new Athlon 64 5000+s.

    Sounds like AMD brought that back!

      Well supposedly the QX chips have an unlocked multiplier. See the review here:

        Yes I have looked at several test reviews and they all push up the multiplier as far as 12.

        The issue seems to come back to your mainboard. The bios may not be correct at this time. Have you checked with mainboard manufacturer?

          No, that was going to be my next step. Although I doubt they'll do anything.

          Tempted to send it back and get a Gigabyte P35-DS3L. All solid caps, changing the multiplier... pretty tempting. That's probably the one I should have bought to begin with. But I'll give Biostar a chance first.

            The Black editions and the FX series from AMD and the X (extreme) editions from Intel all have unlocked multipliers. Otherwise you are limited to your CPU speed divided by your FSB. Ex, C2D E6400 runs at 2.16 with a (quad-pumped) FSB of 1066. So take 1066 divide by four (remember it's quad pumped) to get 266mhz, then divide that from your CPU speed, 2.16GHz, and you get a multiplier of 8x!

            You can always go down, A64's (K8) go to 4x with a 200mhz bus, Intel's it depends on the series and model. My Q6600 only goes from 6-9x.

            Just remember that it's the CPU, not the board that sets the limits on the multiplier.
            Q6600 @ 3330, 2x2GB G.Skill @ 888, HD3870, 2*250GB in RAID 0, 1680x1050 22"
            T5470 (1.6Ghz), 2x1GB Corsair, 8600M GT, 160GB, 1680x1050 15.4"
