    for what exactly?

    vcore reads 1.392 V.

    stock vcore is 1.325... so its not that

    You'll need to hit the AMD site and get the data sheet on the CPU, to find out exactly what it should be. The higher it is from nominal, the higher the CPU temps will be.

    The other possibilities are either the CPU heat spreader is not flat, ot the HSF contact area is not flat.

    Actually the case fans may not matter as much during the brief boot sequence as they might during prolonged heavy use. Not to say you shouldn't check out the case cooling, but I think it's the least likely culprit in your problem.

    How much deviation would it take to cause problems?

    Is there anything else that could contribute to the problem? IE, multiplier set too high, or do you think this is a purely mechanical issue?

    to vcore, or not to vcore

    Cap, the x3 720 is my cpu and 1.312-1.325v is the stock vcore, it really is a rather cool running cpu. i have mine cranked up to 3.8ghz @ 1.536 and these are the temps im running with adequate airflow

    i really don't think that's it, something else is going on

    im with you cap, mechanical problem

    in all this, did you check the rpm of your HS fan?...i apologize if i missed it in the thread

    stock HSF is running at just over 3000 RPM.

    still having the high temps bedouinrising?

    That is a very high Vcore. 70mV over the standard Vcore and approaching 1.4V. IMO, check using multiple programs like SIW, CPU-Z & CoreTemp to see if the VCore really is that high. If it is, lower it down to the stock value via the BIOS and see if it makes a difference. IMO, it should make for a drastic improvement in temps.

    Yeah, still having temperatures over 60 c at bootup. I never changed the vcore value, so it should be at stock value, but i'll try lowering a bit more, down to 1.325, see if that helps.

    PS. CPU-Z and CoreTemp are both reading a Vcore value of 1.392 as well as the BIOS.

    Set core voltage down to 1.264 and still experiencing high temperatures at bootup...

    btw, appreciate all the help, guys!

    Then it can only be the TIM coating being too thick, or the bottom of the HSF not sitting flush with the top of the CPU.

    ok, i just tighted the HSF mount again, but the problem persists.
    Temps are high with thermal paste, without it, or with more thermal paste than normal, so maybe this could be an airflow problem...

    There has to be a problem with the cpu or how the motherboard is reading the temp,i don't believe it would be the stock heat sink or paste because i put the one that came with my 720 on a X2 6000+ and that topped out at about 55 degrees,the 6000 was still the old 90nm one with a 1,4v core and it ran fine no overheating warnings.

    I don't see how it could be an airflow problem,unless you are allowing hot air from a heater or hairdryer to get in.

    bedouinrising,
    are you sure the the cam on the HS clamping mechanism is locking down completely?
  16. BMfan

    BMfan TechSpot Guru Posts: 451   +33

    Check the hook at the one end before you clamp it down,it took a couple tries before it hooked properly when i was putting it on the 6000+.

    bedouinrising Newcomer, in training Topic Starter Posts: 90

    100% sure, red.
    I'm just puzzled as to why the alarm only goes off during bootup. It must be a motherboard problem, because while i'm in windows my cpu temp is never more than 55 - 60 celsius under full load.
  18. bedouinrising

    bedouinrising Newcomer, in training Topic Starter Posts: 90

    Its clamped down securely, and the hs is making contact with the cpu.

    red1776 Omnipotent Ruler of the Universe Posts: 5,847   +64

    yep BMfan, thats what i meant also, if its not seated over the notch on the socket frame, it wont clamp down evenly
  20. bedouinrising

    bedouinrising Newcomer, in training Topic Starter Posts: 90

    i'm telling you guys, the HS is securely fastened.
    Here's a question, would a BIOS alarm sound even after windows is loaded? Or only before and during bootup?
  21. BMfan

    BMfan TechSpot Guru Posts: 451   +33

    Sorry can't help you with that one,never had the warning,but i would think it would because your motherboard would try to protect your cpu.

    Is that 55 - 60 idle?

    bedouinrising Newcomer, in training Topic Starter Posts: 90

    i even updated my BIOS and found no soloution. I guess i'll just have to deal with it.... lol

    BMfan TechSpot Guru Posts: 451   +33

    Is there anyway you could try your cpu and heatsink on another motherboard?
  24. bedouinrising

    bedouinrising Newcomer, in training Topic Starter Posts: 90

    unfortunately i dont have another AM2+ or AM3 motherboard to use

    can you show us pic's of your setup so we can get an idea of what it looks like inside your chassis?
