In the world of 2,5" laptop drives the power consumption is already very very close to SSDs. Take a look at the seagate momentus 5400.6 drives: 0,8W idle and 2,85W write power. Something like a Corsair Force SSD has 0,5W idle and 2W operating power.
    i just pull out some numbers

    but yes you are right an SSD saves power.

    the biggest profit is the time to get from idle to action status HDD's allways slow to do that.

    and if you don't compare an ssd to super slow notebook hdds then you need to compare an ssd to an 15000 upm sas hdd because the speed matters

    then ssd win much higher ...

    Guys, thank you for input! Especially MU_Engineer!
    The true reason behind Athlon II x4 inefficient Vcore setting is simple - they are masking defect (turned off or defect cache, defect cores etc) Phenoms II as Athlons II. Phenom II is unable to work under 1.4Vcore and same as X3 vs X4, it seems AMD is unabIt runs and consumes electricity, but its not internally addressed.le to remove the power off completely from the defect chip or cache. On the contrast true Athlon II Propus cores only need as much as 1.15 Vcc to function stable at 2.8Ghz. Which was one of the reason I switched not only the graphics card to AMD, but the system itself - the chip may cost cheap but it should definitely not waste megawatts via deactivated cache or similar. As an "Otto-normal Burger" I don't own a nuclear powerplant in the backyard, nor am I interested in investing into pretty inefficient high-cost solar panels.

    Core on other side, although as it seems pretty cut down at factory, does not utilize the cut-down parts nor needs to supply them with power.

    I hope AMD will improve in next generation, ty for input!

You could also look at water cooling as that is quiet, water blocks are small and have few clearance issues, and there are blocks specifically designed to bolt to Socket F/C32 and G34 out there, so you don't need to use the clamp-on heatsink retention brackets.

    yes right.

    in generall an watercooling system is NOT passiv means the water pump can go down and an water pump makes noises.

    an Mugen never let you go down and water isn't a good idear with electronic..





    You can also look on eBay for retention brackets if your board does not come with one. They cost $4-10 and I'll bet that some of the sellers even ship to Germany.

    o well nice you get the point i just wana have highspeed with 0dB of noice

    right... my OC-E6600@3.6ghz do have this one right now: http://geizhals.at/a464251.html


    with 2 120cm fan's

    and i have an mugen for an bulldozer system in 2011

You shouldn't be surprised that you would have trouble getting it to fit. You probably will have trouble mounting that heatsink on 90+% of desktop boards as well.
    uuhhh i'm so sorry i just allways do the wrong thing

    ok ok.-.. but if you go eatx you can buy an dualsocket g34 board

    and you can pull 64gb of desktop non ecc ram into

    You can't really just divide the price of a 6-core chip by 2/3 to get a price of a quad-core chip. The closest C32 equivalent to the 6128 would be two Opteron 4122s, which are 2.2 GHz quad-cores. Two of them cost $200, compared to $270 for the 6128. Two 4122s + the KCMA-D8 will run you $490, while a 6128 and an H8SGL will run you $520, so the C32 solution is a little less expensive and a little faster. Yes, it will likely be a wash after you buy heatsinks, but remember that the only heatsinks that will fit on G34 boards are server heatsinks or Koolance's $85 CPU-360 water block. That's it. You can at least use some more reasonably-sized desktop heatsinks on C32 boards that will be quieter than the server heatsinks for G34.
    i don't get the point... the c32 is not cheaper and you can get much more ram with an g34 on an dualsocket mainboard and on the max an g34 system is more powerfull.

    the only problem is the fan cooler yes maybe c32 is better for putting an cooler on.

But they're still pretty awful and apparently you play a lot of Windows games, so I imagine you see pretty frequent glitches and bugs.
    i never count an crash if any game run
