Test setup
Motherboard: Asus Crosshair IV Extreme and ECS A885GM-A2
RAM: 4gb OCZ 1333MHz PC3-10666 C9 DDR3
HDD: 160gb WD 7200rpm SATA HDD
Optical drive: LG Bluray/HDDVD Multidrive
CPU cooler: Coolermaster Hyper TX3
PSU: Nexus RX-8500 850w
Overclocking
I initially used the ECS A885GM-A2 to try and clock the 1055T - although I did manage to push the chip to 3.2GHz this was where I stopped with this board. It simply would not allow any higher regardless of voltage, multiplier or FSB adjustment.
1055T @ 3.2GHz.
Disappointing since I knew the average 1055T should go to 3.5GHz fairly comfortably.
Fortunately hope arrived in the form of ASUS' Crosshair IV Extreme. Probably one of the top AM3 boards and certainly something I would expect to clock the pants off the 1055T.
The Crosshair immediately returned a 700MHz overclock pushing the chip to 3.52GHz. A voltage boost (roughly 0.1v) and FSB increase were all that was needed. I also reduced the multi from 14x to 13x since many 1055T users find they respond better to higher FSB at lower multipliers.
3.52GHz.
Pushing on I was able to fiddle with some of the additional chipset voltage controls and increase both the multiplier and FSB to get the processor to 3.86GHz. An additional 0.06v was all that was needed to push it up to this level.
3.86GHz.
A 1GHz overclock is certainly an achievement... especially when you consider that this overclock is on a very affordable low range heatsink.
Temperature
Temperatures at stock were very good and remained so even under mild clocking but the Hyper TX3 could not keep up with the hex core at full tilt and under full OCCT stress burn tests. During normal usage temperatures were certainly never an issue.
