This is all on stock bios.



If it is crashing on you, then you will likely need to increase the voltage as rv112 suggested. If you have Elpida memory, then you memory clock may not be able to go that high. Signs of a problem with your memory overclock at least with mine was that I would get a solid brown screen for a couple seconds before my game would crash. Signs of an unstable core clock would be artifiacts appears like black tears over the screen before a crash. You can usually overcome an unstable core by adding more voltage till you hit the wall for your card. Let us know how it goes.

Try to increase in +10mV steps, till you get it stable.

What memory is on your card? You can see it in GPU-Z (latest build). Is it Elipda, Hynix oder Samsung?

That's one of the problems I had initially. I don't have a CD drive so when I bought the card, I found installing the right version of AB to be unusually frustrating. I keep encountering the following error ""Some of MSI Afterburner components are expired, missing or corrupted". The image in the picture was pulled directly from HardOCP's review, so it might not be the version of AB I have.

I'm at work right now so I can't check, but I'm pretty sure I have Elpida (Here's my GPU-Z - http://www.techpowerup.com/gpuz/fa53e/)

I'll give that a shot, thanks! What would you recommend I initially drop the memory clock to and how much voltage should I be increasing.

I think the biggest thing I'm trying to understand is starting points and proper increments to increase/decrease clocks/voltage

http://www.guru3d.com/files_details/msi_afterburner_beta_download.html <-- you can download afterburner beta 18 here, supposedly though a newer version will be out soon.

Also from your screen cap you should update your drivers to the newest Nvidia 335 ones.

Honestly, I would probably start just with either your memory or your gpu. I would determine the maximum clocks that you can get for each independently. If you want to try for your max GPU core over clock as quickly as possible, you can set your voltage slider to 100 and keep increasing your GPU clock until you get artifacts. You can try benchmarks to get a quick idea of stability, but the true tests are the games that you want to play.

I can push my memory to 800 for benchmarks like Valley, but I have to scale back to 600 for games such as Crysis 3. I have hynix memory however which usually clocks higher than elpida. You will probably be lucky to get 250 or so with elpida.

Try the following:

1. Switch to LN2 Bios
2. set core offset to +240 in AB

That should give you 1241 boost clock.

Leave memory and voltage at stock. If it crashes lower core by 13Mhz increments. (The best testing method is Far Cry 3 and Tomb Raider but Unigine Valley is also good)

If this is stable add 13Mhz until it gets unstable.

right when the 780 lightning came out there was a shortage of samsung memory chips, so they had to use what they could find, it sucks but they couldnt force samsung to make more frown.gif

Yup, Sony was buying all of the Samsung GDDR5 chips for their PS4 and the huge Hynix factory fire.... what else could they do. Now that things have improved - If MSI would like to take my card back and solder some Sammys on their I would really appreciate it wink.gif
