It has been reported from user claims that the Athlon X2 5000+ running at 2.2ghz is actually a phenom II with 2 cores and the l3 cache disabled. The topic has been spreading sa tpc lately when one user attests to that claim with screenies. He's using the 785G chipset with ACC.
guys ,, baka may nakakaalam ..
board ko is Redfox A785GE
and procie ko is AMD Athlon 64 x2 5000+ @ 2.2 ghz
then pag boot ko naging
Ganito..
what happen ?? masama ba ito ?? di nmn ako ng overclock
naging AMD Phenom FX 5000
paki explain po
rest of the topic here
TipidPC.com | AMD Athlon 64 x2 5000+ 2.2ghz Dual Core UNLOCKED to Phenom Quad Core?
This new processor was released by 4th quarter last year out noticed as it was overshadowed by the new Athlon II series.
Quietly released in October 2009, this Athlon X2 5000+ CPU is the first Athlon X2-branded microprocessor manufactured in 0.045 micron technology. Besides more modern manufacturing process and newer core, there some other differences between this CPU and all other Athlon X2 processors with 7xxx model numbers, based on Kuma core. The advantage of the Athlon X2 5000+ processor is 30% lower power consumption. The disadvantage of the 5000+ CPU is the absence of the level 3 cache. The lack of the L3 cache, and 200 MHz lower core frequency, are the main reasons why this microprocessor performs by up to 10% slower than model 7450, which is the second slowest Athlon X2 microprocessor. The last important difference between this 5000+ CPU and other Kuma processors is in CPU's model number. This microprocessor's model number is a performance rating similar to older Athlon 64 / 64 X2 CPUs. All other Athlon X2 Kuma CPUs have newer model numbers, that can only be used to tell which processor is faster within specific CPU family, but not how much it is faster.
Update (January 2010):
It appears this Athlon X2 5000+ is a Phenom II X4 CPU with L3 cache and 2 cores disabled. It is possible to unlock the L3 cache and one or two extra cores on some of these processors by setting "Advanced Clock Calibration" (ACC) BIOS feature to Auto. When the cache and the cores are unlocked, the BIOS will report processor as "Phenom FX5000 Quad Core". AD5000ODJ22GI CPUs with CACVC AC stepping code are based on socket AM2+ Deneb core, and support only DDR2 memory. Th
ere are many reports of successful unlocking of processors with CACVC AC stepping. The CPUs with CACZC AC stepping code should be based on socket AM3 Deneb core. We don't have sufficient information on how unlockable these microprocessors are. As a disclaimer, be aware that not all processors can be unlocked, and not all motherboards can unlock the cache and the cores. There is also a chance that the unlocked core(s) will be unstable.
As with the rest of the unlockable processor by amd.
The unlocking of the processor is a hit or miss scenario. And even if you did unlock, chances are it could be defective. But hey if you got that particular processor and happens to own a motherboard with acc feature then who doesn't want extra two cores for the price of two. The downside is the availability of these newly revised athlon x2 chips. Been looking at some stores and there are no signs of the Athlon X2 on their shelves. Well to those who are interested, happy hunting nalang. Take note of the stepping code.
Disclaimer: As said the unlocking of these chips is a hit or a miss. Successful unlock could lead to an unstable system, if these cores were defective Phenoms in the first place.
