E4600 or E6300 better cpu for overclocking

[HeXploiT]

I'm building a rig for my lab with an old Asus P5B motherboard. I'm probably going to OC to get as much power as possible. Between the E6300 and E4600 which of these processors would be better for overclocking? Also which would be better not overclocked? Will be using a couple nice sticks of 800mhz 4.4.4.15 ram.

Thanks. 07

The e4xxx series is a stripped down version of the e6xxx with a lower bus speed. They are based on the same manufacturing process so the 6 is going to be the all-around better processor given equal clock speeds and they should both OC fairly equally.

are we talking about the Conroe Core 2 Duo e6300 or the Wolfdale Pentium e6300?

The Conroe.

In that case I'd put my money on the e4600.

Wow, I hate it when they recycle model numbers.

Definitely the E4600.

Excellent thank you. 0/

Ditto.

The e4600 was produced a while after the initial launch, Intel refined the dies (whatever) considerably during those early generations of Conroe chips.

It also doesn't hurt at all that the e4600 has a lower bus speed (200MHz versus 266MHz for the e6300). This means you won't have to OC the rest of the components nearly as hard to get significant OC results on the CPU.

For example, to hit 3GHz on each:
e6300 = 7*428 = 3GHz
e4600 = 12*250 = 3GHz

All motherboards of that era could hit FSB250 (stock for e6x00 was FSB266 after all), not as many could support FSB400+ without serious issues.

Also, as I recall, the e6300 chips did overclock well but even a 50% OC would only yield 2.8GHz while the same 50% OC on an e4600 would hit 3.6GHz (not saying they can hit these necessarily - depends on your particular chip and cooling, etc).

I think the only significant difference apart from clock is the lack of VT-x support for the e4xxx


the e4600 is a lot better to overclock, mult 7x is quite bad...

I have one e6300 (and it uses the same die as the e4xxx, it only have 2MB of l2) and it's a hard CPU to OC, at FSB 400 you will be only at 2.8GHz...
and if you like high FSB with the e4600, you just need to manually set a lower mult...

True, I failed to take into account the specific models the OP was using and focused on the series themselves.
