In some of the reviews I read about the new T-bred CPU, I noticed a couple of things I don't understand. They described it as "unlocked" and that you could increase the FSB to any mhz rating that would run stable, but also that the latter (stability) was more chipset/mobo dependent than CPU. They also stated that the new T-bred did not over clock well. If someone with greater knowledge than I could shed some light please. :confused:

“There is an exception to that rule, though, and that exception is that all Thoroughbreds are and will be unlocked, allowing to run them at 166 or whatever crazy FSB speed as long as the mainboard and memory will support it. Unfortunately, at this point, there is no mainboard available that supports changing the Thoroughbred multiplier without crashing but we'll see that happen in the next two weeks, however long they take.”

Unlocked means

That the multipliers are not locked so you can also change them.

Example

You have a multiper of 10 and a FSB of 100
Not only can you change the FSB but also the multiplier

10x100= 1000mhz

Now overclocked with both multipler and FSB

11x133= 1463mhz

Overclocking via the multipler only effects the CPU, unlike the FSB which effect the RAM, video, PCI, ect.

The only other chips that were "unlocked" were some of the t-birds from 1.2-1.4 However all AMD chips can be unlocked Duron, t-bird, and XP. No Intel chip can be unlocked.

SharkyExtreme took a different route to OCing. Instead of trying to OC the 2200 like everyone else, they took the new Thoroughbred 1700+ and got it up to 2200 speeds on a 166 Mhz bus. Of course like this, it benched higher then the real 2200XP.

Have a look here :

Amdmb seemed to have the best Ocing success with the 2200XP, they got their sample up to a real 2160Mhz.
