Overclocking AMD Phenom II x6 1090T BE


I'm trying to OC this CPU on an Asus M4A89GTD PRO/USB3, watercooled by a Corsair Hydro H50.

I OCed from 3.2GHz to 4Ghz (14 x 286), with a CPU voltage of 1.4V. With this configuration, the idle temperature was about 45*C and 70*C at full load but I got a BSOD on prime's test no. 2 which means that I might have to increase the voltage. However I'm concerned about increasing the voltage any further, given the temperature at full load. What do you think?

  1. As long as it's a Black Edition AMD CPU, it does not matter the core number, you can use the guide in my sig.
  2. Yes, I read that guide. What temperature am I to expect at full load with such a 3.2GHz->4GHz overclock? This is more of an empirical question directed at those who might have achieved this OC. Because my problem might merely be a case of having false expectations.
  3. The safe voltage level for a 1090T is 1.475V. If I were you I wouldn't try and hit that since the safe temp level is 62C and you are already over that.

    I am also having a hard time with stability with my 1090T at 4GHz. I can get mine to run at 60C for the first test of prime95 after that it usually wants to jump up to around 68 which I don't let it do for long.

    If you want to see 4G you are going to have to go about it a different way or get better cooling.
  4. i must 2nd the "better cooling needed" if you want to go higher. The H50 isnt bad, but the new H60 blows it away, the H80, or H100 if in the budget are good buys. just check your case vs. the size of that H100. for the dual push/ pull set up, you need damn near 4 inches of clearance. the H80 will fit anywhere/
  5. i had problems getting to 4ghz i had to stick with 3.8ghz at 1.55 volts in end and runs stable never had any problems i did some looking around and went in alot of forums asking why i couldnt get higher but keep getting told theres not as much head room for the 1090t to overclock past or up to 4ghz if u do get there then your lucky!.
  6. oh and my temps are at 33 idle and 45 load
  7. @stew198269 thats a lot of voltage for your 1090t i don’t even have mine that high and im running 4.33

    @einherjar 70c is way to hot for a 1090t drop back you oc until you have proper cooling

    If you could possibly fit this in your budget, running 100% distilled water and a kill coil in the reservoir, (kill coil also available at Frozen CPU), get steam distilled water from the local grocery store, this is a really good performing kit for the AMD, for the money.
  9. What's your case? What's your max budget? 1.55V max and 55ºC or less for avoid problems.
  10. If you have a Phenom II x6 1090T BE then there is no need for you to adjust the FSB. Turn off Turbo core adjust your multiplier to 20 and waa laa 4Ghz. I am running 4ghz on mine and it is air cooled. Current temp is 27 celcius and while gaming it gets to 40 celcius. You might want to buy a new heatsink and try and optimize air flow in your case as best you can. You should never let your CPU get above 60 celcius. Doing so may result in damage to the cpu or motherboard. I typically will only let mine get to 55 celcius at max just to be safe
