    The Quad alone can hit 250w when overclocked and overvolted. A factory overclocked GTX is around the 200w mark and more if pushed hard, or around 130-160w for the gts if pushed, and then add on to that whatever else he has.

    Re: Quad Core Thread: Overclocking, Cooling, Motherboards, Troubleshooting & General

    Right, after repeated attempts to bring my load temps down to a respectable level, I've decided that it might be worth lapping my CPU. Even with everything on stock, it was hitting 55°C under full load, which is madness for a watercooled rig!

    The other thing that makes me wonder if my IHS is not flat is that there is about 7°C difference between cores 0 & 1 and cores 2 & 3, which no amount of adjusting the nuts on my heatsink has made any difference to. I remember taking the IHS off my Athlon 64x2, which made a huge difference, not sure if you can do that on a Q6600?

    Cheers,
    Stephen

    Same experience as well jez. Orthos 3 hrs @ 3204 stock voltage
    OS Vista 32
    Idle
    C0 38
    C1 36
    C2 36
    C3 39

    These are average but do bounce around a little.

    Orthos at 3 hrs

    C0 55
    C1 55
    C2 45
    C3 45

    Somebody like to explain that.

    Ortos x 2 renditions affinity set to 2 cores on each.

    Air Cooling on Tuniq 120 fan @ 2100 rpm.

    Re: Quad Core Thread: Overclocking, Cooling, Motherboards, Troubleshooting & General

    You dont need to lap your CPU, it might give you a couple of c off the temps, but then your warranty is gone.

    55c is absolutely fine for a quad core CPU. Think about it, 4 cores, not 1 or 2, but 4, so it is bound to get hot.

    So is 55c the hottest core? and the others are 48c?

    If I remember right, the IHS is internally soldered.

    Did you get a backplate? I cant remember.

    Yes, I did get a back plate. 55°C is full load, but NOT overclocked. Running it at 3.284GHz, 1.3v (from CPU-z, can't remember what it is set to in the bios) I am hitting 66°C, read from Coretemp.

    Current load temps (overclocked) are:
    Core 0: 66°C
    Core 1: 66°C
    Core 2: 59°C
    Core 3: 59°C

    p.s. I'm not too worried about the warranty

    Still nothing wrong with those temps.

    Its odd that you cant get them more even by tweaking though.

    Good luck with the lapping

    Re: Quad Core Thread: Overclocking, Cooling, Motherboards, Troubleshooting & General

    Or you could send it back under the warranty and say its to hot even with the stock heatsink (might have to pay restocking fees).

    Anyway I got bored this morning so Im back to see how far this chip of mine can go so far Ive booted into windows at 425x9, with 1.59v-core and 1.60v on the bridge but isnt stable for long as the boad craps out.

    Im going for 400x9 now with 1.50v-core (under load) and 1.55v on the bridge.
    Currently idleing at 47c and load under 70c.

    Those temps look fine to me.

    Sorry - I've not been following closely, but what water cooling do you have. From what I've read, only the very best can handle the heat output of a quad and your temps are right up there with the very best air cooling which seems about right.

    Nearly there, 385x9 with v-core at 1.50v and northbridge at 1.6v,

    Core 1:69c
    Core 2:70c
    Core 3:69c
    Core 4:70c

    Should be able to get 450x8 when the X38 Quad gt arrives on my doorstep in october.

    IMO the modern watercooling gear (even the very best) is operating on it's limits cooling an overclocked/overvolted quad. Probably similar temps to what you'd expect from a top end air cooler (eg, Thermalright 120-Ultra extreme).

    Re: Quad Core Thread: Overclocking, Cooling, Motherboards, Troubleshooting & General

    OK, I finished lapping the IHS and put the Q6600 back in. Load temps are now (overclocked to 3.284GHz, 1.35v):

    Core 0: 52-54°C
    Core 1: 52-54°C
    Core 2: 50-51°C
    Core 3: 50-51°C

    Definite improvement, I think you'll agree! I'm much happier now temps are still creeping up slowly, but I have to wait for the Arctic Ceramique to break down a bit, which should drop them back down again a degree or two.

    *edit*

    For comparison, here's what they were before:
    Current load temps (overclocked) are:
    Core 0: 66°C
    Core 1: 66°C
    Core 2: 59°C
    Core 3: 59°C

    Cheers,
    Stephen

    Looks much better.

    Any chance you could put 1.40v through the v-core and put it under load for a few minutes and let me know the temp you get as Im loading at 60c just wanted to know if it could be improved.

    don't suppose it happens to be a much cooler day (like it is here) than pre lapping (like it was here when you posted that previous temp set)?

    Just a thought. Ambient temp makes a huge difference to air and water cooling

    Hi Zak,

    I checked the load temps before I lapped them and they were a couple of degrees lower than the the ones in the comparison (hottest core was at 63°C), so still a good 9 degrees or so of improvement. Room temp has stayed more or less the same reading the temp of the thermometer on my clock.

    Cheers,
    Stephen
