Lag Spikes and FPS Drop m17xr3

I was wondering if anyone else had some info about lag spikes. Right now any game I play, from mw2, to bf3, to skyrim, to just about anything, will have lag spikes. Perfmon and other monitoring tools shows no cpu spike or ram spike. I never get hot, I never use more than 50% of resources, firewall is off, I am hardwired to my modem, drivers have been tested from the alienware support site drivers to the nvidia drivers, bios was a09 and set back to a08 because of known issues with a09. settings in games have no effect, fraps running to check fps. 

Essentially, I can be running a game and then every few minutes it will drop in fps and lag will spike. I only really notice it in games. Never in other processes on the computer. Happens frequently in games. I was just testing bf3, and on ultra settings I can run smooth for about 30+fps and then suddenly drop to 1-5fps and then after about 30 seconds it will go back  to normal. With mw2 that I am playing, i can run 130+fps and then when it spikes it spikes down to around 15 fps. 

Personally I dont think it is a usage thing on the system, but a fps drop. No other system except games is affected. FPS is the only thing hit, as graphics stills show fine, just lower fps. 

I am kinda at a loss now. The only final thing I am going to test is RAM. I had 4gb ram preinstalled and changed it out to 8gb of kingston hyperx ram. I am going to switch back to the 4gb here in a sec and test it out, but not crossing my fingers.

Re: Lag Spikes and FPS Drop m17xr3

So i changed my ram back to the stock 4gb is came with, and kept trying my game. A small drop in FPS for normal use, which is to be expected a little. The lag spikes and sudden fps drop only happened once or twice again and has not happened since. i am going to try out some other games that were having the trouble too and see if the issue is corrected.

You might want to download GPU-Z to check your temps.

 The GTX 580M / M17X Throttling issue It is well known and has been heavily discussed on a number of forums.

Re: Lag Spikes and FPS Drop m17xr3

I use speedfan to check my temps, and been running around 50-70 C. I think it is the throttling of the 580m since about 60+ I start hacing lag, and under that I dont.

At least it seems its not the ram haha.

@ PhoenixBennu : you are saying that the problem is the RAM that cause dropping in FPS ?

im using M17x R2 and having same issue like you for every game i play, even sometime watching youtube.

to solve this , i just have to go out and buy new RAM for my laptop ?

I do not know if anyone has tried, but the problem was in the BIOS. Not sure what is the exact problem, but here is the link to the new BIOS by DELL and install it. It is quite fast and my stuttering was gone. Also i saw a better framerate in Planetside 2 and SMITE.

Re: Lag Spikes and FPS Drop m17xr3

hi, i have kind of the same problem...i buyed this m17xr3 ( i7 -2630QM CPU @2.00GHz ,8GB RAM, NVIDIA gtx 560m, hdd 320gb) -refurbished

i had no problem with it besides the webcam wich i couldn't install until this day...so far so good...played bf3 mw3,max payne 3,starcraft 2,shogun 2, g recon everything running smooth...

THE PROBLEM is that i recently installed assassin's creed 3 , it was running smooth until yesterday when i started to have  lagging spikes from time to time ..i'm playing 5-7 min then i get this lag for 2-3 min or something like that...and now any game i play acts like that...i only experience this lag durin gameplay..it's strange..what went wrong?...the only thing i did was increasing the virtual memory from cntrl panel beacuse i was getting this low fps while playing shogun 2 (wehn scrolling the outside battle map) but i did this before installing ac3 and had no problem

I updated bios but no result -still lagging

tomorrow i'm  going to the shop for technical support but i would want your opinion too,it;s frustrating 😞 a lot of money and now i need some tiem to wate to solve it i guess

Re: Lag Spikes and FPS Drop m17xr3

Bogdan90,

In your case I would recommend running hwinfo64 and logging all activity on your system during the lag and then going back to check everything. What I assume you are noticing is a spike in gpu temp.

Be sure to update directx. This has been known to cause some of these lags. Also, try the basic uninstall and reinstall of the game. I would also check logging with other games to see how they compare to ac3. I have no lagging issues on ac3, so there is obviously something abnormally causing the issue.

I would also suggest resetting the virtual memory, potential to default or app controlled.

Please, also check with FRAPS to see how much of a drop in FPS you are getting while playing.

Post the log filed and other info back here and I will be happy to give it a look. 🙂

Re: Lag Spikes and FPS Drop m17xr3

I  mailed u the logging activity during the lag...(didin't know how to post it here sorry:P) , the virtual memory is set to recommended , 18-23 fps normally ( maximum settings) drops to 3-4 fps durin lag:(..

So..first i readjusted the virtual memory beacuse i was getting low fps when playing shogun 2(  suggestion taken from a forum) the result was preety ok.....(no problems with anything so far) then i installed ac3..played it for 2 days i think..without having any problem...then suddenly yesterday when i was playing it it started to lag.....i thought it was the game's fault but checking the other games i found out that all act the same now  😞 could it be a software problem or a physical one ( gotta mention when i installed ac3 i played it in bed and the lap top got heated up a bit)...

many thanks for your time

Re: Lag Spikes and FPS Drop m17xr3

I am going to take a look at the logging, but right off the bat it sounds like a possible airflow issue. If you are comfortable doing so, then check the airflow.

First, put the back of the hand up to the vents and see what kind of flow you can feel. The back of the hand is more sensitive to this. Then pull off the bottom cover, and inspect the fans. Dust should be apparent. Then pull out each fan. There are usually just a few screws to loosen, and the unplug the power jumper and pull out the fan. This will allow you to see easier any dust buildup along the heat sink.

Use a can of air to clean. Never use your breath. I even use a q tip from time to time.

There can also be lingering damage from overheating, but it is pretty unlikely if it only happened once. I will be checking for things in the log, though.

Here is also a helpful article about check on lagging and frame drops.
