MU_Engineer :
Both manufacturers sell some CPUs that have more cores in the physical silicon than are turned on and active. They've been doing so ever since there were dies with more than one core aboard. However, the manufacturer always sells the CPU as being a lower-core model, such as AMD selling the Phenom II X2 as a dual-core unit despite the physical die having four cores. So you're only buying and paying for a dual-core, not a quad-core. Usually the disabled cores were permanently disabled and there was no way to turn them back on, but only AMD has allowed people very recently to try to turn them back on, so the issue of "locked cores" has gotten much more popular than it was previously. The processor being run as sold with the disabled cores remaining off has passed all of the reliability and functionality tests on the remaining cores and will be equal to a processor whose die never had any of the extra, disabled cores aboard. The fact that many of the current server-class CPUs have cores disabled means that the vendors absolutely feel that the units run just fine with some cores disabled.
If you still want to avoid buying a CPU with disabled cores, then you want to avoid the following Intel chips as well:
- Core Solo (dual-core with one core shut off)
- Celeron 400 and later series single-cores (dual-core with one core shut off)
- Dual-core Xeon E5500 series units (quad-core with two cores shut off)
- All of the quad-core Xeon 5600 series units (six-core with two cores shut off)
- Quad-core Xeon 7400 series units (six-core with two cores shut off)
- Quad-core and six-core Xeon 6500 series units (eight-core with two or four cores shut off)
- Quad-core and six-core Xeon 7500 series units (eight-core with two or four cores shut off)

OK so Simple no need to Bring Long Parghraps just say yes or No & sure !
Answer these Questions with Yes or No ( true False )
1.If i get i5 760 all cores are Unlocked for 100% ! no need to unlock them & they will Perform 100% will with 4 Cores !
2.if i get amd cpu i should unlock cores but if i get Intel i wont !
3.Core Lock take 2 Cores no matter if ur Cpu is 6 cores or 4Cores !
4.it only happens in AMD Six Cores !
5.it happens in INTEL too !
5.Unlocking 100% deepends on the Mobo that we get !
7.will Phenom 965 BE , BE Locked from begining & i should unlock it ?
8.it happens from first or in some Cases ?
9.In fact 2 cores of INTEL & AMD CPUS are Locked & only AMD can Unlock it & intel doesnt have that Ability ?
Remember only YES or no , if u want add something just add a Short Words .
1. Yes, the only thing that the Core i5 is a core i7 (quad core) with HT turn off.
2. Err... yes... Thats if you get an AMD cpu that has useable cores and/or has locked cores.
3. No, There are people with Phenom II x2 that unlock to the 3 cores cpu that didn't take it to 4 cores because the 4th core is not functional.
4. no. There are only few cpus that are 6 cores with 4 cores (the phenom II x 4 960T for example). All of them last i checked, are either not out or were given to OEM's (like dell or HP).
5. yes and no. Yes intel has disabled cores (as MU pointed out) and no as no motherboard maker has attempted to unlock these cpu's. (most desktop cpu's from intel have there are native core count. So it's not a well targeted market for unlocking cpu's.)
6. Acctually it's more or less 25% motherboard and 75% CPU. Most motherboard makers have gotten the "unlocking core" stuff down like art. It's more or less the cpu you have to worry about if it unlocks or not.
7. 965 BE is a full quad core that cant be unlocked further. In fact there nothing to unlock as it even has an unlocked multi for overclocking purposes .
8. can you rephase that question? I dont seam to understand what you're trying to ask.
9. Correct, only AMD motherboard have the ablitity to unlock cpu's while intel doesn't.
Sorry if some of these go beyond the "just add a Short Words" but sometime a few words dont mean anything unless you write a sentence or two.
Hope this helps.
