Hey all; I've been a long-time reader, but I never signed up and posted until now. Thanks in advance for all your help :-)

I have a pair of GTX 670 4gb cards (one Zotac, one EVGA). Via Precision X, they both have a synchronized overclock of about 110mhz (I assume they aren't entirely identical, but whichever one downclocks itself to mirror the other card is only a very small difference). I have an i7 2600K and 16gigs of Kingston Hyper X RAM.

Installing the second GTX 670 brought my 3D Mark 11 score from 9000 to about 12,000. Needless to say, I'm ecstatic to now be able to play Crysis 2 at 2560x1440 with literally every damn setting set to Ultra and being nearly FROZEN at a perfect 60fps. However, most of my internet research indicates that a pair of GTX 670's with an i7 should garner about 14,500 points or so. I'm reaching out to everyone here to see if there are any deficiencies in my setup (or, perhaps more accurately, which of the following factors might matter).

1. My RAM is running at 1333mhz, not 1600mhz. My ASUS P8-Z77 motherboard will let me turn on the BIOS setting for "Performance" (illustrated by the speed guage with a flame beside it) but whenever I try to enable XMP in the BIOS, the computer clicks off, clicks back on, and says that the overclocking attempt failed. I'm not sure why.

2. Similarly, while I have an i7 with a Corsair H80 liquid cooler, I haven't been able to manually overclock all 4 cores. The basic setting of "Performance" turbo-boosts my i7 to 4.4ghz when it senses that it can, but I believe that this is only one of the cores (is that correct?). My attempts to manually select a new speed in the BIOS (as described as being very easy by many reviewers of my processor) result in the same result as issue #1, the computer shuts down, turns back on, and says that the overclock failed.

3. I am only running PCI-E 2.0 That's the setting that the motherboard was running by default. I've read that PCI-E 2.0 is still not saturated by our present day graphics cards. Is this true?

4.. (This one may be relevant to the previous three). I haven't updated my BIOS since the introduction of this new processor and motherboard (August 2012); would an updated BIOS possibly be the reason the XMP and overclocking aren't being allowed? I had assumed that it was some commonly-known peripheral setting in my BIOS that everyone else knows to enable that I've been missing, or something.


Basically, I'm thrilled with the additional power added by this new card, but I want to make sure that I'm making full use of its potential, and getting 2,000 3D Marks less than what seems average (12,000 instead of 14,000) is at least worth my investigating.


Thank you again,

I already stated in the above thread that I have an i7-2600K that sometimes overclocks itself to 4.4ghz, and that I have an Asus P8-Z77 motherboard.
