    Default Gigabyte P965 DQ6: Problem with Q6700

    Hi all,

    I've had a self built machine, with a P965-DQ6 motherboard, a Core 2 Duo E6300 and 2 Gig of DDR800 RAM running windows XP for a while. I've got a 530Watt Tagan PSU powering it with a ATI 1950XTX graphics card.

    On the whole it's worked perfectly, with the minor proviso that stress testing with Orthos will show up problems with the RAM unless I keep the RAM multiplier knocked down to 2.66 rather than 3 (so I'm running the RAM at 709 rather than 800).

    So, as GTA IV won't run as smoothly as I'd like, I thought I'd try upgrading to a Q6700. Gigabyte claims this is supported, and it's basically a faster version of the E6300 with 2 extra cores, but using the same FSB speeds etc, so memory won't need to change.

    Gigabyte claims I need BIOS F11 or later to support this chip, so I tried installing F13A. With this (and the Q6700) installed, I found that the machine would sometimes take ages to boot, and when it finally did, it wouldn't initialise the graphics card.

    The harddrive would churn away for a while as it loaded windows, and (I assume) got as far as the Welcome screen. When I hit the power button, it then shut down again.

    Every now and then (once every 5 or 6 tries), it would actually boot to the desktop.

    So I dropped back to BIOS F12. Same problem.

    So I dropped back to BIOS F11. This seemed to work, and I had the system running well over the weekend like this.

    When I tried to start the machine this morning though, it rebooted randomly after a few minutes of use (not while under any significant load). 15 minutes later, it went again. And then again.

    And then it refused to start up the graphics card.

    In disgust, I've put the Core 2 Duo back and I've been running with that all day with no problems at all.

    I've seen reference to someone else having what sounded like these kind of problems, in a thread elsewhere, but it was mixed in with other messages so I couldn't see any clear resolutions.

    Can anyone suggest anything? Or should I just sell on the Q6700 and live with my lowly E6300?

    Has anyone had such problems and fixed them? Has anyone actually got a Q6700 working in a DQ6 based machine?

    Thanks,

    Robin

    Update: I've been running the board back with the E6300 in for a few days now, and yesterday, on a reboot, I got the same "several false starts, then start up with no graphics card" problem.

    I always suspect power supply when things like this happen, so I swapped the PSU for my spare brand new identical Tagan 530W PSU, and after a couple of reboots the same thing happened with that.

    So I'm now suspecting a motherboard problem...

    When I run CPU-Z, the Core Voltage reports itself as a value varying between 1.168 and 1.296, with the number varying randomly within that range every second.

    Should I be seeing this amount of variation? Is this a sign that the voltage regulators on my MB are on the way out? If so, I guess we might reasonably expect the situation to be worse with a quad core, which is why it might only just have shown up...

    I'd be interested to know from other people what sort of variation they get on their motherboards.

    If this is my motherboard on the way out, can anyone recommend a replacement? The DQ6 appealed to me because it offered such a nifty cooling solution; heatpipe, almost silent etc. Getting another board that can run my existing memory, CPU and Graphics card would be great...

    Thanks,

    Robin

    Your cpu-z volt variation is probably due to the power saving options being enabled in the bios. This shouldn't be a problem with non-overclocked systems.

    The issue with having to underclock your ram doesn't sound good.
    If you post your current bios settings using a P965 bios template, we might be able to sort things out.

    If you're looking to upgrade, the EP45-UD3P or EP45-UD3R are excellent boards for about $110 - $125 (USD). Given the current low prices for DDR2 memory, I'd suggest 2x2GB of high performance 800 or 1066 memory. Avoid the value ram especially if you want to overclock your system.

    The variation in CPU voltage may be to do with the EIST or Speedstep feature of the CHIP/MB to reduce volts and Multiplier when there is little load on the CPU. I think your Problem may be with RAM or your graphics card. The fact that your ram wont even run at stock speed would have been a red flag there. Run Memtest 86+ V2.11 for several passes to determine if there is a problem with your ram. Then if that passes try using a different video card. Also remember after flashing your BIOS to load optimum defaults. Look at http://forums.tweaktown.com/f69/bios...h-guide-27576/ to find out all the good stuff of flashing.

    Thanks all for your replies.

    I'm afraid I tired of the unreliability, and bought a new motherboard (an MSI P43 Neo-F). The quad core CPU is working perfectly in that, with the same motherboard and RAM (though the RAM still has to be clocked down to 709 rather than 800 to make Prime95 happy).

    So, I have a Gigabyte P965-DQ6 with Core 2 Duo E6300 sitting idly by in a box here - if anyone believes it really is just a bios tweak required to make it stable, feel free to make me an offer :)

    I'm tempted to buy some shiny new RAM for the new MB, because I can get some 1066 stuff and hopefully get a decent speed boost out of it...

    Thanks all,

    Robin
