strange nvidia system tools pop ups

any time i launch a game and come back to desktop, i get about 3-6 of these blank pop up and my system tools screen is also blank

im using the newest system tools and ive tried reinstalling a couple times, with driver sweeper

im overclocking to 600/900/1300 on the 8800mgts. my temps are not going past 81 degrees


any suggestions? what could these be?

 

This may be completely unrelated to your problem, but I've found that my 8800 runs more stable when I maintain the stock 1:2.5 ratio of core:shader clocks. Maybe try upping the shader to 1500?

Actually, I think I may know what those are. After you click "apply" on your overclock, wait about 30 seconds and it'll give you a popup of about that size. It'll ask if you want to apply your overclock at system startup. Answer yes or no according to your preference. Otherwise, it'll keep giving you popups like that. They're probably all blank because while you're running the game in the background, the notebook doesn't have enough free RAM/cpu to render the popups and ntune application.

 

this is something ill definatley try.

can you give me some sample clock ratios? im still a little new to oc'ing

 

Well, I have the same card as you, and stock clock is 500 core, 799 memory, 1250 shaders. If you divide shaders by core, you get 2.5. So any core speed that you set, multiply it by 2.5 to get your shader speed. From what I gather, it used to be impossible to set shaders independently from the core until recently, but even now that it's possible, I get the best results when maintaining the default ratio.

 

ok gotcha, thanks. what would the formula be for memory clock? if i divide shader by memory clock or memory clock by core clock, its a non rounded number.

lets say i wanted to overclock my core to 575, my shader would then be 1437.5. should i round up to 1438?

 

I'm pretty sure you can manipulate memory clock independently of core; it's probably still best to stay around the default ratio though. I use 610, 910, 1525 normally; when I play Crysis I sometimes up it to 625:925:1550 but it usually crashes after a bit; it used to be stable when I created a profile policy with nTune which lowered the clocks once the GPU hit 85 degrees until it cooled down to 70. However, nTune broke on me and none of the profile switching works anymore.

I'm thinking about playing around with the memory clocks and maintaining the exact stock ratio +/- 1 mhz. If you try it, let me know your results.
