The E6750 has a better OC capability than the E6600. It's a locked CPU. There's no such thing as a lowered or highered E6600.
Yeah you can lower the multiplier, but you can't raise it.
If you're overclocking, the E6600 is a way better value with the 9x multiplier. Makes a huge difference with bottlenecks.
No such thing???? Umm you really shouldn't jump to conclusions. Here is a CPU-z Validate link with my username here and a CPU-z screenshot of my E6600 running a 8X multi not 9X. I can run a 6X-9X multi. Can go down just can't go higher than 9X.

Hey I was helping someone on the forum overclock there E6750 and after doing some numbers as we were going I realized a E6750 is a E6600 if that makes any sense.
E6750 clocks at 2.66Ghz with a 1333FSB
E6600 clocks at 2.4Ghz with a 1066FSB
Difference E6600 uses a 9x multi were the E6750 uses a 8x multi.
So essentially if I drop a E6600 multi to 8x and set the FSB at 1333 I get 2.66Ghz the same as the E6750.
So i'm wondering to myself would it be smarter to recommend E6600's over E6750's? Because you get a better multiplier for a higher possible clock vs FSB and then you can run it at 8x and see were it could clock as a E6750.
Am I missing something here. The only thing I could see as being different is the newer steppings.
Ihuser said:The thing is that Intel build their CPUs on the same architecture, but the way they put the speed setting is actually from scratch. They lock the CPU once done. The speed and settings are determined by the model. They don't take a E6600 to unlock and mess with it.
The E6750 is cheaper though, so the E6750 wins either way
also this happens a lot, lets say you need 1000 more E6420's for an order, and your overstocked on E6600, then you send 1000 E6600's through a computer change the default settings, and the CPU ID and you got yourself a E6420, if you look at the SN on your chip you might have actually gotten a higher rated chip
Exactly, that's what I've been trying to point out. Higher multiplier is better because it takes load off the FSB, which is more of a bottleneck than the CPU in most cases.the reason its cheaper is because its a lower multiplier which means less load on the cpu, and more on the FSB, which means they can have a weaker architecture.
EDIT
which means worse OCing, so if your OCing guys get a E6600 or another 1066 bus chip
