670 overclock low and still locking??

Hi,

been trying to overclock my 2 EVGA 670 ftw's (both are liquid cooled) but getting really poor results
using precision x following this guide

http://www.overclock.net/t/1265110/the-gtx-670-overclocking-master-guide

here are my current stats

as you can see am only +60 on the GPU I can run both Heaven and 3dmark 2013 with no problems but when i try any graphical game i.e. Metro, Grid 2 it freezes

just think this is very low any ideas?

Something is a miss here, its not hitting boost speeds and gpuz isn't picking up memory size. Think a clean out of drivers and appications is in order and start from scratch.

It does sound like a driver issue also look at the motherboard drivers and update them too if needed.

I have my FTW at +135 core and +100 memory stable at everything and sits at about 37c.

my EVGA 670SC 4gb's can only manage +11mhz 1145mhz boost as well (watercooled also) I would have spected more than that from your FTW cards

thanks guys ill have a go,

i did install latest drivers but wouldn't snap windows to each screen so went back to driver 320.

i notice memory was showing 0 and thought that was a bit strange

also my boot drive is an ssd and its sitting on bootup for about a 1-2 mins with a black screen before windows starts. :confused:

Hi all,

still no joy ive updated my drivers to 327.23, but still the same story +60 works with benchmark tests but crashes with games.

it is showing memory now

My three EVGA 4GB FTW's all boost to 1215MHz on water.

That's with the offsets on EVGA Precision set to sync, +50MHz for GPU clock and +750MHz for the mem clock, power target at 120% and voltage set to 1100mV.

ok, something very strange is going on.

i set my setting to 1100mv power +120, Gpu +50 with stock memory settings

ran grid 2 game crashed.

run EVGA oc scanner using 3000mb for 6 hrs no crash.
oc scanner runs gpu at 99% burn in test btw.

:confused:
