GT 240 512MB DDR3 Overclock Limits?

[Guest]

I have a Galaxy GT 240 512Mb DD3 non-oc'ed reference card. I used MSI Afterburner to get my card to 690 core, 1681 shader, and 1020 mem stable at 1.050v and 6 hours of MSI Kombuster. I start to get artifacts if I OC the mem or shaders/core any more. What I want to know is, what is an average overclock for a GT240? MY core clock is overclocked 26%, the shader around 27%, and the memory 12%. How much of an overclock is that? Thanks.

How do you know what voltage you have?
how many extra mV did you added on MSI Afterburner?

I don't think I can reach those speeds, I will try though

Oh, I did some Googleing and found out that most graphics cards have a default voltage of 1.050v. And I couldn't adjust the voltage on Afterburner, since the GT 240 has a maximum 75W intake from the motherboard.

That's weird, I am using Afterburner and it works great.

Do you see flickering on your screen?
or no at all?

I really want to use this card and use it around 650Mhz, but it produces flickering

Right now I am overclocking like a baby, in increments of + 15Mhz, to see when exactly the flickering starts

On some games like A.V.A. the card doesn't flicker at stated settings but in games like BFBC2 I start to get artifacts and flickering. BFBC2 becomes stable at around 650 core 1640 shader, and 975 mem.

I am testing with windows
in Windows, if I overclock to, let's say , 640Mhz Core, and 2200 Mhz memory, it will flicker

even the Nvidia driver might crash

TOday I've been testing the card, I am only overclocking the core and the shaders simultaneously

current speed 595 Mhz, not a single flicker

I hope I can least get to 626 Mhz

Which driver are you using? I'm using the latest one, 258.sumthing

 

[rafarataneneces]

258.96

So when do you see flickering?
What is your max stable overclocking speed?

Thanks for your response

 

[Guest]

My max stable is listed in the first post. But I'm the one asking a question, can someone please answer?

This guy had 562 Mhz on the core, 1900 Mhz on memory

This guy has 825Mhz on the core, 2340 Mhz memory


This other guy:

This guy had 825Mhz, 2010 Mhz memory

I have been using the computer all day, not testing, just using it, watching videos and stuff

I currently have 610Mhz, and memory I think around 2100 Mhz is stable for me

I don't think I'll be able to reach much higher
