GTX650ti boost 2gb OC advice

[mercurikun]

So I was wondering what are some good OC numbers for this card, I just bought 2 of them and put them in SLI. But when I play with my 2k textures n such on recommended settings from Geforce experience I get some low FPS dips, I've turned off AA and AF but it doesn't seem to help. So my logical thought would be to OC my cards for some boosted performance. I'm currently boosted to 1200Mhz on my boost clock and 6048 on my memory clock. How much higher should I go?

Probably wouldn't want to go too much higher, especially since my understanding is that the TI range is already set at a higher stock value for both the clock and memory values, you really should be fine with DUAL 650s, SLI setups often suffer massive micro stutter/FPS issues, have you researched anything?

Id even suggest perhaps you have a bottleneck, what game are you playing? When Skyrim first shipped, it was noticed that it was suprisingly heavy on the CPU rather than the GPU. If you've had a look in the CK you'd notice why. What CPU, exact model etc, are you running?

Its not micro studdering that's causing the low FPS I ran into that previously on my 550ti, Its just general low FPS. I have seen benchmarks with dual 650ti boosts that have 125 FPS averages on max settings which is why I am concerned. As for a bottleneck my CPU is a core 2 Quad Q9650 3.0Ghz not OC'ed.

Just a tip: Never turn Anisotropic Filtering below 4x. No remotely modern card should even lose any FPS at 4x Anisotropic Filtering. Most cards can run it at 16x and only lose 1-3 fps. If you want the optimum mix of performance and quality, set it to 8x.

 

Antialiasing should also usually never be run above 8x. More is overkill and a massive performance drop. Even 8x Antialiasing is excessive.

I use 2x in most of my games at 1080p. Between 1080p and 720p, 4x antialising is recommended for most people. Between 1440p and 1080p, 2x is recommended.

 

Make sure you're not forcing Ambient Occlusion in your Nvidia Control Panel, and check to see if the games you're running are known to have issues with SLI.

 

 

I've found that GeForce experience is not very accurate in certain games. For example, it wants to set me at ultra settings in Assassin's Creed 3, even though I average 20 fps on ultra. At the same time, it detects low settings in Battlefield 3 even though I run it at 50-60 fps on ultra. O.o

I have a single GTX 660 GC, by the way. Core speed of 1037 mhz. I can run Skyrim on ultra at 40-60 fps at 1080p with a mix of 4k and 2k textures and 2x MSAA.

If it skyrim microstuttering this can solve it. It has with me.

 

problem solved.

 

Multi threading.

its not the gpu, it's your quad or anything higher, skyrim is not optimized and will cause fps and microstuttering.

Ok I'll fix my AA and AF then thanks. Really I just play Skyrim most of the time. I bought the 2 boosts just for it because my 550ti wasn't cutting it with the texture packs. but I know what you mean with the program screwing up settings. It claims my system specs are below recommended settings for MechWarrior Online

For some people with varying models of cpu, those tweaks can actually make the problem worse. Other times they can fix it. You must have gotten lucky with it, but I recommend that people benchmark the game before and after to check for any real differences.

 

It's far more likely that Skyrim's shadows are killing his cpu, or that his cards aren't scaling correctly in SLI. Skyrim only uses 2 cpu cores for most of the work, and the other 2 handle really minor stuff. Actually, Skyrim can slow down more with 4 cpu cores than with 2, depending on the speed of each core. Skyrim has always been touchy with multiple cards as well.

 

Edit: Have you updated your video cards' drivers?

Yep Geforce experience keeps them up to date for me
