Default Re: E6750 Just a lowered E6600?

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.

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.

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.

Exactly were the E6600 only needs a 1600FSB to reach 3.6 a E6750 needs a 1800FSB.

I'm debating about just running a 8X multi myself. I've gotten 3.6ghz stable with a 9X multi. Thats about as high as I want to go. Thats with a 1.5375 Vcore. I've tried 3.7 with a 1.55 Vcore but it errored pretty quick so I'd say my limits probally roughly 3.65 if I really want to push it.

My thoughts are if thats as high as I can go I may as well open the FSB up and increase the overall bandwith some more.

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.

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.
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

Theres nothing to stop anyone from changing the setting themselves. Just look

E6600 at default 1066FSB/4= 266 X 9= 2400Mhz
E6750 at default 1333FSB/4= 333 X 8= 2666Mhz
E6600 8X multi 1333FSB/4=333 X 8= 2666Mhz

Looks like they just dropped the multi and raised the fsb to me man.

Welcome back to the forums Rudster. I believe you put a good spin on this. The E6750 is cheaper then the E6600. Why would that be if the E6750 was better? It wouldn't be. The E6600 is far better chip because you have the option to run it with a 1066FSB or a 1333FSB. The fact is you nailed it on the head. If they need certain chips they just run them back through the machine for another shipment.

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

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.

Ya I understand exactly what your saying. My point is if you buy the E6600 and say your max stable overclock is 3.6ghz then you run into temp issue's or just can't get it any higher you have the option to knock it back to 8x and see if you can get that same clock but improve the overall bandwith at your max overclock.

This has a advantage to get a bit more performance out of the chip when you can't go any higher. In your case though were your getting 3.8Ghz it wouldn't make much sense to down clock yours. Your running roughly a 1688FSB were a 1668FSB at 8X for you would only be 3.37Ghz. For you to get back to 3.8Ghz with a lowered multi you'd need a 1900FSB. Possible but unlikely. But if you could your memory would run that much faster.
