    Ok here goes my shot at bench leaderboard:





    GPU @ 1070MHz
    GPU Core @ 1.050v
    GDDR5 RAM @ 1900MHz
    CPU @ 43/43/43/43
    680m SLI / 3940XM rig in my sig
    _________________________________________________________




    GPU @ 1071MHz
    GPU Core @ 1.050v
    GDDR5 RAM @ 1800MHz
    CPU @ 43/43/43/43

    Already peaked @ 407W from the wall!!! I'ts getting interesting and Im so building a DUAL PSU mod...!!!

    Here is an interesting comparison... still just having some fun and not doing serious benching yet. Still sitting in my recliner, R2 on the lap, no AC, no dual AC adapter.









    • CPU Clocked @ 4.7GHz
    • GPU Clocked @ 1130 Core /1168 Memory / Overvolted 1.1v
    • Cooled by 10,000 BTU portable AC unit
    • Dual 330W AC Adapter

    • CPU Clocked @ 4.5GHz
    • GPU Clocked @ 981 Core / 1400 Memory / Stock voltage (1.0v)
    • Cooled by fans only - ambient room temperature 68°F
    • Single 330W AC Adapter






    • CPU Clocked @ 4.6GHz
    • GPU Clocked @ 1072 Core / 1500 Memory / Overvolted 1.085v
    • Cooled by 10,000 BTU portable AC unit
    • Single 330W AC Adapter






    And this is kind of interesting...

    Batman Arkham City Benchmark: 580M SLI > 7970M CF > 680M SLI > 780M SLI (all at stock GPU core/memory clock speeds)

    Notice I brutalized the 580M SLI with the highest settings and it still held up fairly well under the most extreme conditions. When you look across the board at average FPS instead of min/max anomalies it goes to show that spending a lot of extra money for the latest and greatest GPU is not necessary to have a good gaming experience.

    I was actually surprised how cool my 680m's can run at 1.1v, no doubt 780m's can do that too with some extra cooling!

    Also, can anybody look up my CPU core's temp @ 43x4 pull in above screenshots in TS? I think I could do with new repaste job? or is that ok such fluctuation in temps between cores?

    Yes, and I will definitely be doing that when I get around to benching for numbers in the next week or two. For now I am just experimenting to get used to them.

    But, that wasn't the point of my post. Rather than achieve a high score, I was trying to demonstrate the performance of the three different configurations in 3DMark11. The 680M SLI benchmark is 1.1v and was beaten by 780M SLI with stock voltage and a lower core overclock. I was also attempting to show that the 18 had to be pushed much harder to get a 3DMark11 score similar to the M18xR2 with 680M or 780M SLI.

    I have trouble keeping the 18 running with 780M SLI at 1.1v and CPU overclocked. It shuts off rather abruptly. The M18xR2 also shuts off with 780M at 1.1v and CPU overclocked using a single AC adapter. There's just not enough juice in the 330W AC adapter to meet the demand for that if the CPU is cranked up for combat mode. I had the same trouble with 680M SLI running at 1.1v but the 780M is a little bit more demanding due to the higher TDP.

    The M18xR2 with 780M SLI is like a totally different computer than this new 18. The R2 really likes the 780M SLI and handles it extremely well. I am amazed at how much cooler 780M SLI runs on the M18xR2 compared to the 18. Fans that work right are a nice thing to have, LOL. I think the highest temperature I have seen on the GPUs is about 75°C and they can easily hit 85°C or higher on the 18 when overclocked.

    Yes, 680M SLI does run really cool. It's an excellent GPU.

    To answer your question, that's way too hot for only 4.3GHz. You should not be seeing 100°C or higher at 4.3GHz unless you're in a really hot environment. I am running cooler than your example at 4.5GHz. For 43x4 you should need no more than 15, at the extreme most 20 if your CPU is unusual, for Flex VID. Pri Plane can be set at zero (Auto) up to about 4.5GHz without hurting performance. If you are running more than 20 on flex and more than 896 Pri Plane (which is the same as "0" because 896 is the "Auto" maximum) that may be contributing to high temps. If you are already using these settings, then I think you do need to look at a repaste.

    If you want to improve CPU performance, disable BD PROCHOT in the BIOS and remove the check mark in ThrottleStop.

    Well now I'm really NOT looking forward to that 18 coming tomorrow. Oh well it's pretty to look at:)

    It might be something about this one that is not quite right. I am praying that yours is able to do stuff successfully that this one cannot.

    Well I always have the other option; you Bro know what I'm referring to. I have Windows H8.1 Enterprise Edition on now and am really liking the eye candy and snappiness of it. Who knows maybe my benching days are over, at least I went out with a bang.

    Well, you can still definitely get your game on. This 18 mangles the life out of any game I throw at it as long as it doesn't need a lot of extra CPU horsepower.
