I caved... Quad GTX 580 UD with new AC waterblocks.. New 990X and new 1500W PSU

    Here's some baseline prime95 temperature tests with stock CPU clocks. Im still astounded at the idle temp at stock clocks.. Even at 5Ghz it idles at 35c which is 6c less than the 950 was at 4.6Ghz.
    As I speak air temp is 22.7c and the CPU is idling at 16c with default clocks.
    The 990x runs at 0.97v in powersaving mode at default clocks combined with massive surface area of 2 x 360 rads just for a CPU and Aquaero controller water block.

    Below is a quick prime95 run at default clocks.
    Processor voltage runs at 1.12v for default clock of 3.4Ghz under load.
    Note the CPU radiator fans are sitting 3.7v which is 800RPM the whole time.
    The CPU T8 sensor is a thermal probe sitting just under the heat spreader between the 990x spreader and circuit board. Not sure why its reading so much lower, its probably slightly damaged and needs to be replaced or re-positioned.

    Really not sure how the AC Kryo HF Silver can improve on this but I'll give it a shot when it comes.
    AC said about 10days for all my order to come in which means about a month for delivery! :(

    For some reason the one string of CPU fans on Ch7 that used to report RPM no longer does. The other one has a dirty RPM signal which is why it reads higher than its actually spinning.
    Im hoping that when I re-cable and sleeve everything it will fix this as I'll use higher quality wire than what ships with the fans.

    The GPU loop is only cooling UD9 and Ram at the moment but you can see the chipset generates a bit of heat under load even at stock settings.

    I have the system almost stable at 5Ghz now. Enough to get through Vantage graphics tests and halfway through the physics test. Ill keep tweaking today and should get it stable by later tonight.
    I was running with 1.6v vcore and vtt at the max for testing and temp wasnt a problem so its not vcore/Vtt is probably the IOH or skew.. I'll keep trying.. (thats with memory at 2000Mhz 9-9-9-27)
    The CPU runs fine @ 5Ghz with 1.45v and 1.35 VTT so I'll reset there and try tweaking elsewhere...

    Ok got my 1st 5Ghz @ 1.63v Vantage completed.
    I had to drop the 580's to 880/2200 @ 1.077v to keep under 100c as the high clock speed of the 990x was working them harder.

    enjoy! :):)

    I found the limit of the new power supply... :wired:

    CPU 5.22Ghz 1.66v :shock: with 920/2250 on the GPU's. PSU did an overload shutdown as temps were still fine! (well yes the CPU was a tad hot but not at tMax)

    Looks like I might need me a 2nd 1500W PSU to split the load when I overclock the GPUs under water.

    now what you need is 3 x 30inch monitors for the ultimate setup.

    Also any old parts for sale Phatty ?

    Phat, i jizzed. Nice system. But TBH 1.66 volts is ALOT. Id just stick with 5

    Also, seems you use onboard sound? You need Xonar Essence STX to complete it, and nice speakers/headphones :banana:

    I doubt that chip would last long at 1.66V although that's one hell of an overclock at 51%.

    This. I really hope you didnt buy all that beautiful stuff to throw pixels onto a single 1920x1200. I got nothing against my samsung t240, but I didnt spend that much on my stuff :D.

    These are the best I can do for now until the GPU waterblocks arrive.

    Almost 60K Vantage and 19K 3DMk11.

    Tried going to 920/2250 on the GPU's but score went backwards, weird!

    This is with 5Ghz CPU, 900/2200 GPUs.

    give the 270.61 a try
    i got my highest score on those (12K +)
    from what i heard they are very good for sli

    That's some expensive shipping :3eyes:

    How much total spent so far!? And wouldn't the i7 2600k have been a better buy?
     
  17. Phatboy69

    Phatboy69 Guest

    Nope 2600k would have required a new MB and I wanted full 4 x 16x PCIE for QUAD SLI, which none of the 2600K chipsets support anyway.

    Re-shipping, Yeah well Australia is long way from anywhere else down here! ;)

    I'd have to go back and add up the previous build components that im keeping in the upgrade, but last build was about 12-14k, so far just the upgrades for this build are closing in on 9k.

    Awesome, may I ask what you do for a living? (so I know where to start :nerd:)
    Also, I think MSI has PCIe 3 now that runs at 8x with two gpus which equals to 16x speed for PCIe 2 but not sure if they have quad models for that...

    Im in IT sales for a global telco selling enterprise hosting, outsourcing and global networks.

    Yeah but PCIe 3 slots not much good with current PCIe2 cards!
