GA-870A-UD3 CPU max withstand TDP?
« on: January 29, 2011, 02:13:21 pm »
Im using GA-870A-UD3 with Phenom II x 555 BE which is running at 3.8GHz@1.45V & quad cores unlocked.With the help of  Easy Energy Saver,it shows me the CPU Power Wattage.When I'm running 3DMark11,it shown 7xW~14xW.I think its acceptable for me.But when running Prime95-Torture test,the CPU is under 100% full loading,the Power Meter shown ~180W.I'm wondering is this safe to run the stability test under this high power consumption?Will it fry the mobo VRM or other components?I see that the mobo can support up to 140W...Wii it withstand 180W?!!

I wouldn't worry, I'm running almost same settings as you with the same CPU + the CPU-NB volts are 1.250v ( overclocked to 2,65Ghz ). I have the same 8+2 power phase design on my board. The only thing you may want to check is if your power section isn't running too hot under load as your board has no heatsink there.

The GA-870A-UD3  rev 2.1 supports the Phenom II X4 965 (CPU part number HDZ965FBK4DGI). This model has a Thermal Design Power (TDP) of 140 Watts. There are no CPU's with a higher TDP supported.

The Thermal Design Power (TDP) is the average maximum power a processor can dissipate while running commercially available software. TDP is primarily used as a guideline for manufacturers of thermal solutions (heatsinks/fans, etc) which tells them how much heat their solution should dissipate. TDP is not the maximum power the CPU may generate - there may be periods of time when the CPU dissipates more power than designed, in which case either the CPU temperature will rise closer to the maximum, or special CPU circuitry will activate and add idle cycles or reduce CPU frequency with the intent of reducing the amount of generated power.

TDP is usually 20% - 30% lower than the CPU maximum power dissipation.

I'm not sure what correlation the Power Meter and Phenom II x 555 BE have, as the TDP of the Phenom II x 555 BE (CPU part number HDZ555WFK2DGM) is only 80 watts.

1) GA-Z97X-Gaming 7, G3258,
2) GA-990FXA-UD3 Rev. 1.1, FX-8350
3) GA-AM1M-S2P, Sempron 3850 Kabini

His is unlocked to a quad core and runs overclocked. From what I've seen in reviews, 180W seems to be about right for these CPUs at these values. Still, it shouldn't be a problem ( other than obviously slightly shorter lifetime of the motherboard and CPU ). It's important to add that 180W is under 100% load.
