GTS 250 overclocking difficulties

post #1 of 2
Thread Starter 
When I use msi afterburner and adjust the core/shader/memory I run the RE5 benchmark and I also tried this with Kombuster and it crashes, so I take it down a little and when I run them the next time It gives me like 6-7fps when before it was running the benchmark I was getting 50-70fps before it crashed. Then after I reset the card back to stock it runs normal. Is it a problem with afterburner or am I setting it too high? I mean I even tried bringing everything down a lot and I still get 6-7fps. What would cause it to crash the most? Would it be the memory being too low or too high or the shader? This is my first GPU overclocking attempt, I'm just looking to get some more fps out of my games. My card is a BFG GTS 250 OC 1Gig with these settings Attachment 159214 Any help would be appreciative, and especially what settings you think would be optimal at stock voltages, thanks. Also, this was what I was testing it with before on someones suggestion for speeds 790Core 1300Mem 1950Shaders. I even dropped this down a bit and it caused the same problem.

I don't use MSI Afterburner, and I really have no clue about your single-digit fps issues, but I thought I'd throw in some speed comments. My EVGA GTS250 came slightly higher clocked than yours (770/1123/1890), and I get artifacts or crashing any higher than 800/1208/1964. 1300 sounds too high to set your memory to as a starting point, I'd try something closer to what mine does and see how that works for you.

It's also possible that your gpu just doesn't overclock well, if you've tried lower settings. It's not uncommon for the factory overclocked cards to not significantly higher than they shipped.
