    Did you check any of the voltages (suggetsed above) whilst running the X3 tc demo with Hwmonitor, to see if the 4670 was loading your board to a detrimental level?

    It sounds like either a compatability problem with the card vs the board, the card not being able to access enough current through the pci-e slot (for a number of reasons), or possibly a faulty graphics card.

    Edit:-
    I don't know how accurate this review is and I can't see any mention on the specific need for a Pci-e rev2.0 slot on the 4670's ATI product page:-
    ATI HD 4670 Review - Graphic Reviews - TrustedReviews

    Simplifying things further is the HD 4670's power requirement. It also doesn't require any extra power connections as it draws all the power it needs from its PCI-E 2.0 slot. Essentially, so long as your computer's motherboard has an x16 PCIe-Express 2.0 slot you're good to go.
    I believe the power capacity was raised for the PCI-e 2.0 sockets, yet our PCI-e sockets on the GA-P35C-DS3R are version PCI-e 1.1

    I think this aspect needs to be looked into a bit more - maybe an email to amd/ati?

    Well spotted Vorlon, the 2.0 requirements completely slipped me by to be honest; would make a lot of sense if that was the problem.

    I can't find anything (other than that particular review) that says you need a PCi-e 2.0 x16 slots as a requirement.

    It's like my 8800GTS is a Pci-e 2.0 card, but I have no problems with it and all the data I've found suggests it's backwards compatable. It does have additional power though.

    Just another thought! I know both cards you have are ATi, but did you uninstall the drivers with the 38xx in place and not allow the system to reload them? If not, you should, then;
    Remove the card and then physically install the 4670. Don't let windows attempt to install anything (GPU related), but then install the catalyst drivers.

    I wonder that if you haven't done this, that the 4670 isn't being setup properly.

    Nah I definitely set it up correctly. It does seem irrelevant though as I can reproduce the problems I'm having without ever going near the operating system.

    I might see if there's a cheap card I can pick up to test this on. I think this power to the card thing is the issue at hand.

    edit: That said it is weird that I can get it to work using the methods I posted already, and that it only doesn't boot from cold.

    Have you tried contacting the manufacturer of your card? What make is it anyway?

    Powercolor and no I haven't tried them yet. I'll try it when I get a sec.

    Do check the voltages with Hwmonitor whilst running a benchmark though. The reason for this, is that your Pcie 1.1 slot might be sufficient for your 4670, but now current (power) is being "drawn" through the motherboard alone, any weaknesses there will be highlighted.
    For instance is your 20/24 pin and 4pin atx plugs providing sufficient current. Have you a "true" split 12volt power supply where one of the 12volt lines goes solely to PCie 6 or 8 pin plugs. If that were the case, it could mean that you only have a percentage of the power resources from the PSU available.

    By using HWmonitor, the voltage sensors which are on the motherboard, can let you know if there is a problem where the board itself (or the connections to it) are the "weak link".

    I would bet your other PCIE 2.0 card is fine because of the PSU Cable that powers it, although your board will run a 2.0 card with it's PCIE 1.1 slot as said above the power allowed thru it is not up to spec with PCIE 2.0 and this is likely the cause of the issue. PCIE x16 only has 75W (150 w/connector) thru the Slot, and PCIE 2.0 has 150W (225/300 w/connector) thru it
    http://www.pcisig.com/news_room/faqs/pcie2.0_faq/
    http://www.pcisig.com/specifications/pciexpress/base2

    You can try adding PCI Express voltage in the BIOS, but even maxed out it may not be anywhere near enough.

    So I think you should either return that card for another PCIE X16 instead, or get a PCIE 2.0 that comes with a PSU Connection on it so it can get the needed power from your PSU

    Hi people...

    I noticed these posts today.!
    Was searching for help on this problem I have wats exactly the same problem as Z0mbi3!
    The solution for myself its just turn the switch off on the battery and then turn it back on. My oc is still the same after 6 reboots.. hope it will stay this way!
    Here are the specs I run on....

    SOFTWARE:
    WINDOWS XP PRO. LATEST UPDATES
    BIOS V.11

    STOCK:
    GA-P35C-DS3R 1333FSB
    CORE 2 DUO E8500 @3.16Ghz @3.16Ghz
    4Gyg - OCZ XTC Platinum 1333FSB
    SAPPHIRE HD4850 512MB @ 625/1950 Mhz

    OVERCLOCKED:
    MAINBOARD= 1333 >>> 1464 FSB
    CPU= 3.16 >>> 3.47 Ghz
    DDR3= 1333 <<< 1171 FSB
    GPU= 625/1950 >>> 670/2150

    Incase your interested in some benchmarks?
    3dmark 2006 score = 12618
    PcMark 2005 score = 7901

    ------------------------------


    Because I'm not sure if ddr3 overclocking is stable enough to run at higher speeds then stock, I downgraded the memory from 1333 to 1171 Mhz.
    Memory modules are very sensitive so didn't want to push them to its limits!

    I've seen some reviews about guys who pushed there E8500 up to 4,6 Ghz. WOWW!!
    This is the most stable freq I get ..3.47Ghz .... don't know much about overclocking so I leave that as it is, and don't mess with the voltages and leave it on automatically....

    hope you guys have something here...
    Hope the problem for me is solved just turn off the powerswitch....
    I let you know.. if the stock clocks are returned...

    I've found the same and are running my 1333Mhz reaper 4GB DDR3 kit at 1200Mhz.

    Researching over at the OCZ (and I've noted some over at Corsair) forums some boards (all manufacturers) have problems supporting DDR3 above 1200Mhz, regardless if the DDR3 is 1333, 1600, 1800 or even 2000Mhz products. There is an extensive Asus thread on the OCZ forums about this issue.
    It seems that in the main, the better chipsets/boards ie x48 have the least problems in running DDR3 at the highest speeds, ie 1800Mhz+
