    I would think that flashing the cards "may" make them run like the full version brethren but wouldn't that create even more heat problems as their performance is throttled up????

    I don't know....but, mine is running pretty cool now. I'd always thought I'd do that if I got a quadro, but I just don't have reason yet. It would yield a very large driver selection. Has anyone here done this with a precision?

    EDIT: I put BIOS A11 back on and can't really tell any difference...GPU maxes at 81C all overclocked by 100. ? I'd hope they improved something rather than a software engineer just justifying his existence :D

    The 1mm should not be filled with thermal grease, as 1mm is extremely spaced (thermal grease applications are usually 0.2-0.3mm or less) and renders the heat transfer highly inefficient. The heat sink and the CPU heat spreader surfaces must touch. The purpose of thermal grease is to fill in the microscopic cracks which prevent surfaces from contact, too much thermal grease (pretty much anything in excess to the microscopic cracks) will harm the performance of the heat transfer, due to the increased distance between the two surfaces. By applying a generous amount, you're not temporarily fixing it, you're actually causing it to degrade over time. But as stated, what can you really do. From overclock.net forums:

    @ ElPenguino, once again, 81C with what game and settings?

    I♥RAM: Supreme Commander Forged Alliance, high settings except for one medium setting (can't remember) and shadow detail at low (defaulted so I left it) It pushes the card on large battles zoomed in. My C90s 8600GT would get to about 95C doing that, so it seems 'cool' to me. I stopped in Best Buy over the weekend to get Crysis Warhead and they were out of it.

    @Weegie
    Yes, I am very pleased and surprised. I could not imagine that the speed difference would be so high (more than a factor of 3). I was thinking a long time, if it is reasonable to spend the additional money for the QX9300. But now I see, that the compile speed is mostly CPU bound. Even with a middle class HDD you can get a huge performance increase only with a quad core CPU.

    @I-RAM, I think that thermal paste harms conductivity in the case of your figure, since thermal paste has a lower thermal conductivity than direct -to-metal contact, but it should be helpful in the case of m477hew, where there is no such contact.

    That we do know, and I did state he has no other choice.

    I just installed Vista 64 on my M4400, and the only two drivers that did not want to install were the following two drivers under the "Chipset" category:
    1. Intel Driver - AMT SOL/LMG
    2. Intel Driver - AMT HECI

    The error that comes up when I try to install these two drivers says "This computer does not meet the minimum requirements for installing the software". I'm assuming it is not compatible with Vista-64.

    Below is a description I found about these two drivers. However, I don't have any unknown devices showing up in my device manager, and everything in the computer seems to be operating correctly.

    Operating System Drivers
    Within the operating system, two drivers must be installed to remove unknown devices in the Device Manager. These drivers are discussed below.

    SOL/LMS Driver
    The Intel® AMT Serial-Over-LAN (SOL) / Local Manageability Service (LMS) driver is available on support.dell.com and on the ResourceCD under Chipset Drivers. The driver is labeled Intel AMT SOL/LMS. Once the driver is obtained, execute the file; it unzips and prompts the user to continue the installation process.

    Once you install the SOL/LMS driver, the PCI Serial Port entry becomes the Intel Active Management Technology - SOL (COM3) entry.

    HECI Driver
    The Intel AMT Host Embedded Controller Interface (HECI) driver is available on support.dell.com and on the ResourceCD under Chipset Drivers. The driver is labeled Intel AMT HECI. Once the driver is obtained, execute the file; it unzips and prompts the user to continue the installation process.

    Once you install the HECI drivers, the PCI Simple Communications Controller entry becomes the Intel Management Engine Interface entry.

    Any ideas what this is all about, and if it is important or not?

    Is there any way to get a Blu-Ray player for the M4400?
    There's no option on the UK's Dell site, but is it possible to buy the drive only and replace it (like you replace the optical drive with a HDD)?

    @ElPenguino: We're still at the hardware level, the cooling is not effective enough and so after playing an intensive game for 15 min the card reaches its threshold and downclocks

    @I♥RAM: Exactlyl lol, and btw nice figures. I'm going to have to find some pure copper and machine it down to make a shim, apply thermal compound to both sides and stick it on the GPU.
