Framerate dips GTX560 Ti

post #1 of 38
Thread Starter 
I am posting this on behalf of a friend.
If you need more infomation i am happy to supply it.
Excuse the poor grammer, i have not bothered to Grammer Nazi it because it is still legible.

current Specs:
win 7 x64 home professional
AMD Phenom II 1055t x6 2.8 Ghz stock clock
EVGA GTX 560 Ti 1 Gb (B-stock)
8 Gb (4x2 GB) Kingston DDR3 RAM (unganged)
cooler master 700w PSU
Gigabyte GA-880GM-UD2H
Creative sound blaster

I recently upgraded to a gtx 560 Ti 1Gb, from an old 5670.
i had been running the 5670 for about a year, and it ran most games fine, some at low framerates, but i never had any dips and all my games were smooth.

as newer games with
higher requirements came out, i decided to upgrade to the 560, and forked out the $230 for it. however, i did not get the performance i had hoped. it

runs all of my games at very high framerates (CSS: 300 solid, CoD4 200 solid, BC2 at about 80, crysis 2 around 50
however, i get constant dips. not dips in the sense that my framerate drops from 60 to 30, sips in that the game lags up and chokes on itself for a good

2 seconds and then returns to normal. this usually happens after 5 minutes of playing any game, be it counter strike
or crysis. I'm a noob at computers, so i'm not sure if this is a result of the gfx card/processor overheating, peaking, or what. here is what i do know:

It is most likely not my ram. i have 8 Gbs DDR3 and almost no backround programs running (no antivirus, skype ect)
I don't think it is the gfx card overheating. it was running at 80 C, but with some tweaking on the fan the hottest it get's is 70 C.
i don't think it is my processor overloading. unless CSS uses all 6 cores at 2.8 Ghz, im not sure that is the problem.
after running a cpu intensive game (Bc2, which uses all my cores at near 100%) for about 10 minutes, all my cpu temps where at 65 C.i don't know if they

get any hotter, but this might be a problem.
i'm not using the stock fan, the one i bought is supposed to be better, but it could be the problem. (ran fine with my old 5670)
i run all the games at max settings in 1600x900. all the fancy stuff like MSAA, bloom and HDR. could the 1Gb of Vram not be enough? then again, if it

happens on CSS, i doubt it.
this IS a new 700w PSU from cooler master, and i don't know if the psu has anything to do with it... so... =/
i have the power management mode set to maximum performance, so it is getting the power draw it needs.
my sound card is right on top of my graphics card, which might add to the heat. i have tried removing it, no difference.

alright, i think that's all i have on it. so basically: games run fine for 5~10 minutes, then have lag spikes every 30ish seconds.

any help is appreciated, i have been trying to ssolve this problem for weeks, but have not found any solutions.

Do a complete driver sweep and update.

He has already completed this step.

He is going to uninstall the drivers the normal way this time, then install the latest.

He already used the driver sweeper technique when he first got the card.

Anyways, driver sweeper can cause some issues.

What driver is he using? I recommend trying the 266.58 first then the 270.61.

He is currently on 275.33.

How can we get 266.58 and 270.61 drivers?

I went over to www.nvidia.com and clicked Archived and Beta Drivers, and the history only goes as far as 275.33.

Can you please supply a link for 266 and 270?

The first thing comes to mind are the drivers, since he switched from AMD.

What power supply is he using and how old is it? Any odd logs in Event Viewer?

One thing that he could try after uninstalling a driver is to run CCleaner and check for any unused registry errors. It usually finds a few things that Driver Sweeper misses. I actually never use driver sweeper.

Interesting! I go in and see archived drivers all the way back to 266.66.

Edit 1: And, since he said the 'lag spikes every 30ish seconds', I wonder if this is caused by some background applications?

Thanks.

We ended up finding the driver we needed (266).

He is going to install it (after uninstalling his 275 via control panel), and then he will run some benchmarks to see if it still dips.

As he said the 'dip' happens every 30 seconds or so, it seems this is rhythmic and so it is possibly caused by some background applications. Check for this.
