    Help, 3.0 AMD QuadCore only running at 1.6ghz.

    Hello, I have a "AMD Phenom II X4 940 Deneb 3.0GHz Socket AM2+ 125W Quad-Core Black Edition Processor Model HDZ940XCGIBOX"

    on a "Foxconn A79A-S AM2+/AM2 AMD 790FX ATX AMD Motherboard"

    powered by a "CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply"

    6GB RAM = Patriot Viper 6GB (3 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)

    VIDEO = EVGA 896-P3-1260-AR GeForce GTX 260 896MB 448-bit GDDR3

    BIOS is set to "Optimal Settings" and my system info tells me I have a 1.6ghz and it runs video games pretty sluggish.

    All drivers are their latest versions.

    Also those 3 sticks of DDR 1066 show as 800mhz on the post screen.

    I would try to revert the manufacturer's settings to the default settings.

    Is this a new build?

    Did you ever have different readings?

    Out of curiosity try CPU_Z and see what it reads:

    CPUID

    There is always a possibility of a bad motherboard which you should be able to RMA.

    Do you have the latest BIOS on the board?

    Here's a couple SS of my CPU-Z idk which tab you wanted to look at.

    That is if it uploads.

    Just to verify:

    Do you have the latest BIOS? 782F1PO8 updated: 6/22/09

    If you do have that BIOS try changing the CPU multiplier. Try x 10.0 for starters.

    My FoxOne updater software says I have that version.. but released on 6/17/2009.

    What on earth is the CPU multiplier?

    I really should have just paid extra for the ASUS

    Page 26 of the online manual lists your BIOS options in regards to clocking.

    I assume you have the book?

    If not you need to search your motherboard here (they do not offer direct links):

    The CPU multiplier is the rate that the FSB is multplied.

    Your CPU_Z shows a bus of 200 x 8 = 1600

    Why the FSB is 200 I don't know. That appears strange.

    On re-thought I would try to up the FSB. The manual shows you where these setting are and how to change them.

    I also would search the CPU compatibility list:

    Foxconn - Products: Motherboard

    Which gives us:

    Foxconn Support - CPU Support List

    Yours appears as the last listed model.

    I would suggest trying to contact Foxconn and if they cannot help try AMD.
