Gpu overclock

So I have an m11x r1. I have overclocked my gpu to 550/1320/890 and end up getting a lower score on 3dmark then with the stock settings of 450/1080/790. Is there any reason for this, is my gpu just not good for overclocking or are my setting just unstable?

 

I get a much higher score when OCing and running 3dmark. Howerver the one you posted would not be stable on my card. If I go too far the game just locks up and I have to restart the computer. Stange that you only get a lower score. What is your score with and without?

 

Mine does this too when i set it too an unstable clock. The odd part is that it doesnt crash 3dmark or throw BSODs.

I have no clue why this happens, but it might be because there is another graphics processor to pick up the slack while the 335m recovers from a crash, thus resulting in a lower score. On my desktop when my gpu is unstable, the program crashes saying the gpu drivers crashed or something like that. But this is completely made up and based on no hard facts, just my iffy logic =).

 

search. huge thread or maybe many threads on this. Either way lots of posts.

 

Mine gives worst FPS and low benchmark scores as well including WEI
If the OC is unstable...

 

It isnt just whether the oc is stable or not... I had odd issues with the app.

 

I have looked at several threads about gpu overclocking but none of them had addressed 3dmark giving a worse score while oc'ing vs stock. I had used those settings there to oc because I had seen several people say that was the settings they had used and they were stable. My score was around 6600 stock and it dropped down to as low as around 5400 at those settings.


Edit: Spelling

 

You need to restart your computer after you OC. Although... I'd set the shader clock down to around 1230-1250. You should also bring the Memory down to 840, at least.

 

when your overclock becomes unstable, it knocks your clocks to under stock speed, I believe it knocks it down to 405mhz on the core and the only way to fix that is to restart your system. You need to use MSI afterburner or something of the likes to monitor your clockspeeds while overclocking, if your core becomes underclocked, you can tell it is unstable.

 

I'll bet you're using EVGA Precision. Try using MSI Afterburner instead.

I had a similar problem, which I posted in this thread below. Switching to MSI Afterburner worked for me.

I actually was using Precision, going to try afterburner after I get outta class.

 

i use precision.. never had a problem with it, and you dont need to restart after you overclock lol... never heard of that before. never needed too. and im not sure about your overclock, look at my overclock in my signature.
a lot higher.

 

If I overclock the games will crash on outdated games :x
GFX intensive games like BFBC2/ crysis 2 will not crash...... strange eh? Or is that normal?

 

The clocking you are using is within the bounds of normality and for most M11x owner would produce better results.

I've been using EVGA Precession over-clocking on an M11xR1 without any problems. But I suggest using MSI just for the fun of it.

Now then, even though you have moderate-high over-clocking, it's not to say, your GT 335M is not resetting when OC'd for whatever reason.

You can monitor the clocking in MSI or Precession and you'll see the drop/reset when and if a reset is happening.

What happens if you set the over-clock to 480/1152/810 as a test?

If you get the same results as normal or a small improvement in 3DMark06, then at least you know OC'ing works or at least at this level doesn't reset you card.

It may be that your Nvidia GT 335M chip was dropped on it's head at birth and doesn't do over-clocking.

Dell never designed/tested the Nvidia card to be over-clocked.

Some M11xR1 owners can't over-clock their CPU from 1.3Ghz to 1.6Ghz without a BSOD. How sad is that.

 

I disabled switching and downloaded the new beta nvidia drivers and can now overclock quite well. The only problem is I have a problem with just one game. Left 4 Dead 2. I start a map and streaks come off of all of the chars, it doesnt matter how low I set my oc it always happens unless I go back to stock settings.

 

How much does pinmodding improve your performance?

 

it gives a pretty good performance gain, even just a 130mhz increase on the cpu. (the 1.73ghz pinmod) i went from 7k on 3dmark06 to over 7.6k. later on im planning on doing the 2.0ghz pinmod tho.

 

How did you manage to get 7k pre pinmod? I only get 6800 with everything oc'ed without one.

 

In my own experiments (sorry, don't have the numbers with me) with 3DMark05 I also saw no improvement when I overclocked the GPU alone. And then I underclocked it to 400/960/700, and saw about a 1% decline in score. I also saw that the GPU utilization was rather low.

BINGO! The GPU is being limited by the CPU !

So I overclocked the CPU to 1.6 GHz in the BIOS, and tried again. Massive improvement in GPU score with GPU at stock. Confirmation!

I next overclocked the GPU to 500/1200/800 and score went up further.

So to overclock your GPU you have to first overclock your CPU.

 

I already had my cpu overclocked, had it oc since the day I got the computer. I am able to oc the gpu now just fine after I disabled switching and downloading beta nvidia drivers.

 

good drivers and an extremely high gpu overclock. also i have my nvidia control panel optimized pretty good.

thats 3dmark05 not 06. overclocking your gpu is GOING to show improvements in apps or games that would use it. how do you think i got over 7k on my 3dmark06 score? 7117 to be exact.

also the cpu is the bottleneck, but that doesnt mean a gpu overclock isnt going to help at all.
