Mobility Radeon 4570 HD - Temp And Voltage

post #1 of 3
Thread Starter 
Good day,

I have an Acer Aspire 5738G with an ATi Mobility Radeon 4570 HD.
This laptop always had an issue with temperature but I have been solving them as of lately, but there's still one thing that bugs me.

A friend of mine has an HP with a similar build (same graphics card at least) and he has the voltage set to 1V and the clocks to about 700mhz Core and 1000mhz memory. While I have about 680 Mhz Core and 800 Mhz Memory (which in my case would be standard, and his would be an OC), however, I possess temperature issues while he doesn't.

Is there anyway to change the voltage on my graphics card to his level? Currently it's set at 1.2V...

Thanks in advance,
Kuroh

PS: Have checked online with Google and searched through several forums, used ATi Tray Tools (which just changes back after I try setting 1.000V), AMD GPU Clock Tool (which just doesn't accept 1.000V) and several others. Also read that Riva Tuner might be possible but I find no guides on how to manage such thing.

PSS: Checked some clocks around the Internet besides the ones set as default shown by GPU-Z and such. And found some are 500mhz others 665mhz and so forth.

So I did a change of clocks, Core to 760mhz and memory down to 740mhz... Performance was seriously increased... Will probably try lowering memory and raising core a bit more later on. But although it's still kinda hot (about 72ºC GPU wise, 62ºC CPU wise) it still works well and without issues... Not to mention the huge performance boost is always nice. Would still be good to know if my voltage is possibly messed up tho...

Welcome to OCN first of all!

You could try MSI afterburner if you haven't already might work and while those temps are kinda warm they aren't dangerous. Video cards are good up to 80-90c and 105c is when things start getting bad and damage can occur.

When it comes to voltage all cards are different some have higher VID then others. More then likely your GPU just wont run stable at a lover voltage however you can try the above program to see if it works and go from there. Some cards just run hotter then others another thing to try would be remounting the coolers with better TIM but that might be a task on that laptop.

Since you are overclocking it the higher voltage is better and is possibly what is allowing the higher core speeds you've obtained. Increasing core speeds will have better increase of performance then memory especially if running lower res where lots on onboard memory isn't really needed. The higher the res the more memory is needed to load all the textures and such iirc.

BTW what stability tests are you using to check temps and be sure its stable?

Do you have a laptop cooler if not might want to look into it should help. I assume the laptop has been fully cleaned out since that would help with temps if it hasn't.

I ended up mimicking a friend's Mobility Radeon 5145 when it comes to clocks, not to mention I pushed further a lil' bit... ( 760mhz core, 720mhz memory )

I managed to get similar fps to his so it seems alot better, temperature has also lowered... I don't have a laptop cooler since it's not quite practical 'cos I kinda move around alot between places.

I had however to drill some holes in the case itself since this computer is an Acer Aspire 5738G and had severe design flaws when it comes to cooling... (a fan just spinning into plastic, and HDD and memory without any vents)

The CPU reaches 68ºC max and the GPU reaches about 71ºC max... The CPU and the GPU share a common cooling system (I'm not exactly an expert on this subject), I'm quite comfortable with raising the GPU up to around 85ºC or 90ºC... What worries me the most is the CPU also rising with him due to this very cooling system...

Any idea on how much an Intel Core 2 Duo T6600 can go?...

PS: Used Assassin's Creed Brotherhood and Fable 3 to test the fps (although had no exact number, I could push the graphics further while mantaining fluidity.

PSS: Also sorry for using this post for a different question...
But I'm considering upgrading my desktop's graphics card... Am considering MSI AMD Radeon 6870 Twin Frozr II/OC but there's also a PowerColor AMD Radeon 6950 1Gb at almost the same price...
I was wondering what is the card that ends up being more worthwhile? The MSI that although a weaker GPU it's an MSI or the Powercolor with its stronger GPU?... (I believe this PowerColor is also unlockable into 6970 although memory clocks should stay at 6950 levels I think)

Thanks in Advance,
Kuroh
