amd a10 7850k do i follow the CPU temp or its core temperature



amd overdrive says the core temperature but theres also CPU socket temp what one should i follow?

    so in other words keep my CPU temp in asrock fatlity f stream under 72c?
    very very very far under?

    here's eteknix's findings in their a10 7850k launch review:

    We did also note down AMD’s alternative temperature measurement, known as the “thermal margin”, but AMD told us these cannot be converted into actual temperatures. You can see those thermal margins below. The thermal margin indicates the thermal distance from the threshold at which thermal throttling occurs. The higher the number the lower the temperature because the further it is away from the thermal limit.

    AMD A10-7800K. 70 Degrees thermal margin to thermal threshold at idle, 57.9 Degrees thermal margin to thermal threshold at load
    AMD A10-7700K. 70 idle, 58.2 load.
    AMD A8-7600 (65W). 70 idle, 58.8 load.
    AMD A8-7600 (45W). 70 idle, 65.8 load.

    The overall pattern in terms of temperatures then isn’t really possible to judge but we think the Kaveri APUs will be running at similar temperatures to Richland or possibly slightly lower. Temperature increases are likely to result from a more dense die with a larger GPU part but at the same time the reduced overall thermal output from a more efficient CPU probably counteracts that.

    eteknix's idle temp for 7850k was around 23c.

    i don't know about your temps, but your cooling system could use some improvement, may be (judging by the readings). just 13c margin at load at stock clockrate isn't good. either your ambient temperature is too high or you're using the bundled stock cooler or you didn't fit your cooler properly.

    my CPU was under load by prime95 my cores idle around 12c
  5. Those temps sound about what I'd expect under load with a stock cooler and using the APU graphics. Are the results similar while gaming?

    no its a bit lower maybe 50c? gaming
  7. btw can i tak my a10 7850k apart and replace the themal pad with Ceramic?

    what thermal pad? you shouldn't dismantle the apu unless you're very experienced.
    moreover, you'll lose your warranty coverage.

    does AMD use high end themal stuff between the chip and that metal peice?
  10. amd uses thermal paste as thermal interface material under the apu's heatspreader.

    http://www.cpu-world.com/CPUs/Bulldozer/AMD-A10-Series%20A10-7850K.html
    according to cpu-world.com, 7850k's maximum operating temperature is 72.4c

    according to cpu-world.com, 7850k's maximum operating temperature is 72.4c

    so in theory i could replace the heat compound between the chip

    Yes, but why? Your APU is operating within spec

    ok so i got my TX3 coolermaster installed with coolermaster thermal-fusion 400 and my load temps are as follows
    is this ok

    update with prime 95 it holds stable @ that
  14. looks like massive improvement in thermal margin. however, the stress-tester software is different from the OP.

    updated with prime95 is there room for small overclocks with is in a very very hot room like 85-90F

    so this means i installed my TX3 correctly? lol

    Yes it does. But I can't recommend overclocking just yet because prime95 only really stresses half of your APU - I suspect you'll get higher temps while gaming than under prime 95. You're using the APU graphics, right?
  18. so i can't get the IGPU stable but 4.3ghz cpu oc works after that it gets flaky
