gtx 770 - Unigine score decrease after memory OC...?

post #1 of 3
Thread Starter 
Sorry to starting new thread but there was no response in "[OFFICIAL] GTX 770 Owners Club" probably because to many post there
so i decided to ask you guys in separate thread.

I just don't know what to think about my Windforce 3

I get High ASIC Quality 90.7%

But when it comes to OC I only get stable (By stable I mean few run Unigine Valley and Heaven with NO crash, artifact, and not decreasing score than before OC)
+40mhz on core
+220 memory
So I get in evga precision
1293mhz
and 3726 mem

(I do not change voltage, Im still on stock 1.187 because increasing to 1.212 not change my stable +40)

I think 1293mhz its acceptable in this lottery when in real game It will change very little fps so I accept it, but I wonder what to think about memory because when I push them +400
I get NO artifacts on EVGA OC scanner X (10min test) , I also get NO artifacts on both UNIGINE tests, but my score is much lower than on stock settings.
(I get arround 36fps on stock, 38 on my OC stable but when push memory beyond +230 it drops to 25fps)
So my score is increase only to those +220mhz on memory and started to decreasing from +230.
On 3dmark its OK, increasing normally.

Dont know what can be an isue ? Just bad luck and I should replace my card or maybe there is somwhere else the bottleneck, because I'm still
on wery old computer and maybe this is a problem?
CPU E8500, X-48 DS4, PSU OCZ 700 WAT, win8 32bit
drivers 320.18

Probably after one or two weeks I will get new haswell computer but I only have few days to decide what to do with my gigabyte 770.

Unstable memory, instead of crashing with memory ocs unigine benches just keep running for some reason. You've found the limit when it comes to memory clocks. At least in unigine benches that is.

Thx, for response.
So ASIC quality was just not right in my situation...
Anyway I will stay with card and use it on stock clock smile.gif
It's deffinitly enough for me to the next maxwell generation.
