Gt335 overclocking, increasing clocks = something odd?

hey guys, just wondering if you can help with something, i overclock my gt335 and every program i use, be it afterburner or precision or GPU tool, none of them register the clocks correctly, lets say.. i increase my memory clock, from 900 mhz, to 905 mhz, but it will jump all the way up to 911mhz. why wont it just clock at the 905 instead of going 6mhz higher? or if i go from 911 to 915 it will jump to 925. i just want it to register right so i can achieve my maximum stable overclock.

 

What are you using to overclock GPU?

 

i use, EVGA precision, GPU tool, and MSI Afterburner. all those ive tried and its still the same result.

 

I am not so surprised. Install Nvidia System tools 6.06 from Nvidia site. I use it and have no problems with my GT330m

 

il try that, iv used that before but not since i got my m11x.
il let you know how it goes. thanks

EDIT: still the same problem, im not sure what could cause it to not set the clocks right.

 

Ok,

M11xR1 SU7300 1.6Ghz BIOS A05 4GB RAM Nvidia 260.63/Intel 2020

Connect my M11xR1 to a U2410 monitor via HDMI with Nvidia enabled.

Using MSI Afterburner, I enable clocking of 570/1415/890.

Enabled. Applied.

I view a web site in Firefox 4.0 (GPU Acceleration enabled, just for reference) and the memory clock peaks at 890Mhz before dropping back down to 135Mhz.

If I increase the memory clock to 894Mhz, then MSI monitors peaks of 894Mhz.

If I view the same clocking on GPU-Z then there is a margin of approx. +2.8Mhz, such that GPU-Z reads a peak of 896.8Mhz.
GPUZ-Z still see the same base at 135Mhz.

 

That's weird. My clock speed keeps jumping from 401Mhz to 920Mhz. What driver are you using?

 

I think the card clocks memory in "zones", so an increase in clocks within a range will correspond to one clock speed. I observe this too when I apply 819 and the real clockspeed is 810mhz. When I apply a clockspeed during a 3D load, it's the exact clockspeed, so 819mhz is 819mhz. Hmm.

 

iv tried many many drivers, but right now im on the 270 beta drivers. and i can overclock more on those. and there the most stable for me.
i think gpu-z is the most accurate, also precision reports the same thing for me.

 

il try to set them under load and see if i get the same result.

edit: nope, still the same result under load.

 

For me if I set nnnMhz in MSI or EVGA I see the monitor of these utilities show the same values at peak as those I have set.

If I monitor those same values in GPU-Z I only see a margin of approx +3Mhz at peak.

I don't see any vast difference in values. It's just a few Mhz for me.

If it is agreed that the values seen in GPU-Z are the most reliable, then I'm not seeing much of a difference other than 3 - 4Mhz.

HOWEVER, this doesn't explain why all monitors return the same base clock. For example the memory clock is displayed at 135Mhz no matter what monitor you use. Maybe that base clock value is imbedded in code and not a queried value.

I've not noted any values outside of a range of 0 - 4Mhz on any of the monitors. I've been changing the memory clock and haven't played with the others (Core, Shader) to be fair.

 

hmm.. precision and afterburner report the same clocks just about on the monitor. but its really odd that if i up the clocks 5 mhz they go up 10mhz instead. the 5-10mhz difference could be the difference between being stable and not stable.

 

Did you install and check Nvidia System tools 6.06 and are those values the same as GPU-Z??

If the Nvidia values are the same as MSI and Precision then you know GPU-Z is a fun tool which gives a good indication of the current clocking.

 

yep, i just tried that, same result. i wish i had a workaround for this tho. system tools isnt bad, but the profiles dont work when trying to set them to start up when my m11x is starting.

 

This thread makes me funny People who has 135 base clock. This happens because your system and GPU are in 2D mode (which only means that your GPU does not need to work like a horse to show you that level of graphic (like web browsing and else). 3D mode turns on when it needs to. When you OC you OC 3D mode.

Ajslay. Did you met this problem before install beta drivers? I believe this problem is because of not ideal drivers. As I said mine 330m under 266.58 drivers. Besides why can't you load that settings on start-up? Mine Nvidia control settings offer me always if I want to load that profile or settings on start up every time when I change that settings..

 

i know the difference between low power 2d mode and performance 3d mode.
but iv tried this with 3 different drivers at least. i can achieve an extreme overclock with the voltage mod i helped work on, but this problem still persists, i would just like it to clock at the exact number i tell it too.
