670 not hitting 1300mhz

post #1 of 42
Thread Starter 
I just got the gigabyte 670 and I have it in evga precision +110(max I can without problems) power target 112(max) and it hits 1260mhz max, and when I set the memory at +100 or above it only hits 1215mhz max, but it gets better fps than at 1260mhz. What is up with this card, is it just not a good card? If so, then I guess I can be OK with 1215 but I really want 1300! This whole boost clock thing annoys me greatly!

For most 670's 1200-1250 is about the normal. One of my 670's will do 1242, and the other will do 1215.

Memory OC will benefit you more then Core OC.

1300MHZ cards are rare.

so overclocking memory is more helpful. What a strange new series of graphics cards this is, I hope the next series overclocks the normal way.

Wait, so memory OC is more important to get better frames per second than core OC? This is only GTX 600 series?

I'm wondering why people shoot for higher core OC then?

Different games/settings strain different components, and different cards have different 'balances' between core power and memory bandwidth. So a memory OC is not more important than Core OC in every gaming scenario, nor on every card ... but OC'ing the vram on Kepler is on average way more helpful than it was with high-end (470 and above) Fermi cards (wherein it was almost useless).

Basically, the power of the core increased more dramatically than the available bandwidth did between Fermi and Kepler, so now bandwidth has been brought more into play (as a limiting factor to performance) in the newer generation.

Depending on how much Memory OC you gain by sacrificing (however much) core clock, it may be worthwhile to make that sacrifice. You should do some tests, on a variety of gaming benchmarks, and see which config of core/memory OC works best.

If you look at synthetics, Heaven, for example (esp. with full AA) is quite bandwidth sensitive, whereas 3dMark11 is not nearly as much so (partly because of it's much lower resolution in the standard mode).

As mentioned above, 1300MHz 670's are not that common ... probably only about 35% of 670 samples will hit that mark. Hopefully you can at least get a nice memory OC ... If you can only hit 1215 (max boost) but can at least get +400MHz memory OC (using Afterburner/Precision's DDR3-based calibration), you'll still have a damn good performer.

Bragging rights? @phantasmor personally I have always seen a memory overclock benefit FPS more than core. My GTX 460 is that way, my 7600GT was too.... Cant wait to get a 660Ti, anyway, be happy with that core speed and work on memory next smile.gif Good luck

no, I was talking about the boost clock telling you what your overclock is not that memory benefits fps more, although that is the way it looks when you are reading it.

oh and memory is +800 and getting the same fps as +400

Almost seems the cards people are getting now don't have the high out of the box boost.
Mine boost to 1202mhz at stock.
