Replace a C2D E6300 with a Pentium Dual Core E6700 on a LGA-775?

I have an HP DC7700 Ultra-Slim with an Intel C2D E6300 1.86GHz processor for typical home office use (gaming performance not required, though video streaming is). The spec sheets for this unit say it was offered with CPU's up to a 2.66GHz E6700 C2D so I figured that if I could get an E6700 cheap, I'd do an upgrade. But, in addition to the C2D chip I found a Pentium Dual Core E6700 which runs at 3.2GHz (though with 2MB cache and 1066 FSB .vs. 4MB cache and 1066 FSB for the C2D) that the online benchmarking sources indicate is overall faster.

Assuming it is faster, I am interested in installing this one, but there is one "descriptor" I am unfamiliar with - SLGUF. The E6300's and E6700's all have different characters for this value, so while I know the LGA-775 socket is the same, I am hesitant given this value is different.

Can anyone help me understand what this value describes, and if it would be a deal killer?

BTW - I understand that the e6300's are great overclockers, which I would love to do (!), but I can't get into the BIOS on this HP box. You'd think they would have provided some way/hot key, etc to get in for someone who really needed to get in.

Thanks!

The Pentium E6700 probably will not work. Stick with the C2D version.

C2D
Try F10 for BIOS, just yesterday i had a clients' HP laptop for which only F10 worked
If that fails, F1 F2 Esc Del are other options, seems different keys work in different systems sometimes

If overclocking a laptop, slim one especially, you may want to consider a decent Cooling Stand for it too

Thanks Chris. It's a desktop system...I've gone into the BIOS settings via F10 (had to after power outage killed system clock - must need a new battery) a few times and can't find the clocking settings. From reading online resources, seems the consensus is that the OEM manufacturers lock the BIOS. I'll try the F1 F2 Esc Del combinations and see if that works. Since the FSB and cache is the same as the Pentium Dual Core, overclocking it to 3GHz or so...wondering if that would provide the same performance...for free! :-)
