AMD Phenom II X6 1055T Processor (HDT55TFBGRBOX)

Bought this cpu when the amd 6 core cpu's were being first released. Have it paired with a Gigabyte 880GA-UD3H, Arctic freezer X-treme cpu cooler, and Antec 1200 case. Stock voltage is 2.8Ghz and it is 3.3Ghz with turbo. At the moment I have it running at 3.5Ghz non-turbo fixed speed, at stock voltage. I have overclocked it to 4Ghz pretty effortlessly by increasing voltage, 3.5 is the max you can go with stock voltage you see. Runs very cool, ambient temp 30c, and at 4ghz prime95 full load it peaks at about 50-55 degrees. Have it clocked at 3.5Ghz 24/7 because it is the highest I can go with stock voltage. I don't need the extra performance since it still runs very fast and maxes out all games out there.

I used it for gaming, heavy video rendering in sony vegas, running multiple virtual machines, and hosting game servers for LAN's. Needless to say it does all of that perfectly well with its 6-core architecture and then some. When eventually it runs into performance issues in the future there's always the option to overclock the snot out of it.

Overall, runs cool, good for pretty much everything you throw at it however if you are building a new rig right now a different cpu would be a different option, unless you happen to find this one at a discount price.

I was looking to build a new gaming rig. I have built rigs before but nothing like what I have now. I have owned both Intel and AMD. I chose AMD because I was turned off by the amount of heat Intel chips liked/produced. I also wasn't looking for the best thing on the market, felt the 6 core AMD was the right fit.

These chips are great with good aftermarket cooling, they like the cold, so air cooling or better is recommended (by me). With sock cooling I hit a 500mhz overclock with little voltage increase while staying comfortably under the thermal limit of these chips (60*c). With a aftermarket cooler, my Silver Arrow, I was able to get a 1.2ghz overclock to reach 4ghz (2.8ghz stock).

For stress testing I ran prime95 and LinX at the same time for 24 hours. This chip took that beating and stayed well with in thermal limits and kept on chugging. After settling my overclock I was folding bigadv units, normally reserved for 8 core/thread+ chips and getting the units in with in the deadline. (Want to know about folding? Check out the folding section of the forums for details, help find a cure)

The downside to these 1055t's is that the multiplier is locked, meaning they can, to some, be trickier to overclock. To overcloxk these chips, you use the front side bus (fsb) which also affects ram, hypertransport, and other items when adjusted. Cpu's with unlocked multipliers can use (for the most part, in basic terms) just voltage and the multiplier to overclock with. With multiplier overclocking, small tweaks to the fsb may still ne required to help stabilize the overclock.

All in all, this chip has handled a year of abuse, folding, gaming, and everyday use for over a year now and keeps on like it was brand new. I couldn't be more pleased with this purchase.
