Amd Athlon 64 X2 Dual Core 7750 Black Edition
When it comes to overclocking the Phenom X3 8750 we could raise the base clock from 200MHz to 230MHz to give a speed of 2.76GHz. With Athlon X2 we were able to increase the clock multiplier of this Black Edition processor and zipped up to 3.2GHz without any trouble.
The real surprise lies in the power draw figures as the overclocked Phenom X3 required an extra 30W under load while the Athlon X2 only wanted an extra 5W. As the idle figure in the Windows desktop appeared to drop by 5W we have to say that both figures are within the margin of error so overclocking an Athlon X2 doesn’t appear to require any extra power.

Faced with a straight choice of the Athlon X2 7750 at £80 or Phenom X3 8750 at £105 we would choose the dual core model any day of the week but of course we need to consider how AMD stacks up against Intel. We grabbed the figures from our review of the that was tested with a processor that runs at 3.16GHz. This is a relatively expensive processor that currently sells for £155 however the Intel graphics on the DG45ID are feeble compared to the AMD HD 3300 so you have to read the figures carefully and look at the PCMark05 CPU figure rather than the Overall score. This shows that the Athlon X2 compares very favourably to Core 2 Duo although it has to be remembered that you can overclock the E8500 to 4GHz without difficulty.
A 2.66GHz Core 2 Duo E7300 that costs £97 may have given a better comparison to the Athlon X2 however we don’t have one to hand. That forces us to take an educated guess that the 2.7GHz Athlon X2 has the edge over a comparable Core 2 at stock speeds. Once the processors are overclocked the Intel processor should pull ahead slightly but honestly it’s a tiny margin, unlike the price difference.
I was wondering if anybody had investigated information that has been circulating around the net for the past month and a half or so about using a similar BIOS and board exploit as the Phenom X3 for the X2 BEs? Supposedly, the X2 7750 BE is unlockable from 2, to 4 functioning cores by selecting the correct board (ASRock), the correct, old BIOS version that has weakness in its code allowing the exploit, and by toggling ACC. Allegedly, someone in Korea using Windows XP SP 3 was able to successfully unlock the other two cores, and posted screenshots on a few different forums across the net as verification. I've recently begun investigating the matter thoroughly, and was wondering if anyone else had heard of this, and tried unlocking the other two cores on a X2 7750 BE? I admit it is possible that this is a hoax, but I don't imagine that my preliminary searches' (all of 30 minutes worth) lack of in-depth guides reporting success, or in-depth guides explaining what must be done in what order as has been done with the X3 Phenoms mean that it isn't possible.
I also figure that, true exploit or not, people aren't rushing out to drop a couple hundred dollars on a processor and board that may or may not be unlockable to be more than its initial specs belie. How many people are really going to drop $200 on a new CPU, Board, and RAM just to test whether a rumor is true or not? So, I ask the community, hoping that someone may have uncovered more information on the matter, or have tested this for themselves and may share their results, before I buy a CPU and Board to see for myself. I don't know about that specific CPU, but in general some dualcores and some triplecores can be unlocked by some mobos, though AMD From my understanding, it's a crapshhot whether a particular unit is unlockable.some dual cores or triples may be quads which came off the line with 1 or 2 bad cores. I just ordered a 720 and the mobo is capable of unlocking it, but.if it does unlock, i'll just consider the 4th core to be a bonus. If not, eh.i'm still good to go. Good luck, please report back if you are or are not successful.
