Hi all,

I have EVGA GTX 770 ACX 2GB (not overclocked version, core clock -1046MHz) and I have problem with overclocking. I can get it stable only with +60MHz on core clock which is total 1106MHz (boost clock 1200MHz). I see that GTX 770 models go up to 1300MHz. And I don't know how to get it stable above 1106MHz.

And one more quesiton.. Has anyone played Ryse Son of Rome with very high textures ( 1080p, all other settings on max except supersampling) on GTX 770 with 2GB VRAM? Do you have stuttering? I have stuttering and it is unplayable and don't know if it is problem with VRAM.

Thanks!

Well it is a reference model 770 ACX, +60 isn't bad I suppose. Here's some tips, enable k-boost, overvolt +.12 after you enable K-boost in Evga PrecisonX(Do Not Use new PrecisonX 5.2.3, Legacy version 4.2.1 is the only one that works). I myself run 2x Evga 770 Superclocked ACX in Sli, the best I was able to get out of them was 1280mhz stable(+77mhz offset), which is fine with me, as I didn't pay for either of these 770 SC's(670 FTW Sli Rma). I find 1254mhz core/ 3718mhz memory to be the oc sweetspot for these cards. I haven't had the best of luck with the newer drivers in several games, so I rollbacked to the 340.52(DSR did little for me).
As far as Total War Rome, it is a pretty demanding title, a single 770GTX will not do if your playing at highest settings. Most games that launched in 2013-current require Sli to play at ultra settings in 1080. A single 980GTX just doesn't cut it.

You added this lines to system cfg? 
 
sys_spec_texture=4
sys_spec_textureresolution=4
 
Btw, thanks for the answers!
