QX9650 C0 or C1 stepping = better overclock?

[gwolfman]

Hi,

I'm have the option of selection one of the two, which would be better for overclocking?

■sSPEC: SLAN3, Stepping: C0, Batch#: L745B303
■sSPEC: SLAWN, Stepping: C1, Batch#: L804B467


What are the differences between C0 and C1?

Any advice would be greatly appreciated. Thanks!

get the later steping always as it offer more efficiency or cooler temp and better OC. by the looks of the numbers C1 should be better since "0" is before "1" right?😛

Even though the differences will probably be minimal, get the C1 because it's newer.

Gwolfman, there's another solution:

QX9650 $999.99 - http://www.newegg.com/Product/Product.aspx?Item=N82E16819115034
C0 Stepping, Tcase Max 64.5c - http://processorfinder.intel.com/details.aspx?sSpec=SLAN3
C1 Stepping, Tcase Max 64.5c - http://processorfinder.intel.com/details.aspx?sSpec=SLAWN

Q9650 $554.99 - http://www.newegg.com/Product/Product.aspx?Item=N82E16819115130
E0 Stepping, Tcase Max 71.4c - http://processorfinder.intel.com/details.aspx?sSpec=SLB8W

Non-Extreme variant also has 9x Multiplier, but latest Stepping and higher Thermal Specification for better overclocking.

$999.99
-554.99
$445.00

That's a lot of money to hand over to Intel just to have an Extreme variant with an unlocked Multiplier! Put the $445.00 you just saved into the graphics card(s), or some excellent games and several cases of great beer!

Thanks everyone for the replies. I'll take the C1 stepping then.

@ Tronix: I have a friend who was giving me one, but he doesn't know about stepping 'n all so he let me pick which one I wanted.
