Mobility Radeon HD 4570 OCing guide & Acer driver bug fix

This is my first guide; I made it to help ATI Mobility Radeon HD 4570 users (especially Acer owners who have the ATI PowerPlay Bug. So I hope it is as useful as I think.

Note I: you need to have ATI PowerPlay enabled at all the times
Note II: If you plan to OC this GPU don't undervolt it below 1.2v

First, the needed software:

1- Riva Tuner v2.24 ( http://downloads.guru3d.com/RivaTuner-v2.09-download-163.html)

2- GPU-Z 0.3.9 ( http://www.techpowerup.com/downloads/SysInfo/GPU-Z/) To monitor temps & check that your profiles are working as they should

3- FurMark ( http://www.ozone3d.net/benchmarks/fur/) To stress test the GPU in order to find the suitable clocks


Second, the OCing: (credits go to Twisted-Reviews team the Rivatuner system file edit is theirs not mine)

1- Download Riva Tuner (for windows 7 & vista 64x users you can get x64 Vista assigned drivers for Riva Tuner v2.23 and simply rename them an overwrite the 2.24 drivers with them and when installing Riva Tuner click yes on installing the available updates step after the installation is complete)

2- Open Riva Tuner folder (by default: C:\Program Files\RivaTuner v2.24 MSI Master Overclocking Arena 2009 edition) and open RivaTuner.cfg with notepad

3- Locate [GPU_1002] section in the file and add 9553h to the RV710 Values, Save the file and exit (image 1)



4- Open RivaTuner and you should see that it identified your HD4570

5- For Acer Users with ATI PowerPlay Bug in order for RivaTuner to see that the Default memory clock is 800 MHz instead of 500 MHz and give you a correct memory OCing range you will need to do the next step

a- Enable Low level OCing and don’t change the values
b- Open power user tab and don’t freak out by the message you receive when you open it
c- Locate (RivaTuner\Overclocking\Current Device) tab and follow the image:
d- Now when you go back to the OCing tab you will have normal memory OCing range



6- Since The HD 4570 OCing is Low-level hardware OCing that means you don’t get to choose 2D,3D clocks i.e. no idle & loaded clocks and in order to avoid that you will need to create 3 OCing profiles:

a- Idle clocks one: I will get to how to create it (u should make this the windows startup profile & use the others when you need the extra power)
b- Normal 3D clocks one: Core: 680 MHz, Memory: 800 MHz
c- OCed clocks one: the OCed values for youe new profile ( The highest stable values I reached are: Core: 800 MHz, Memory: 850 MHz) but you should overclock step by step and stress test to find a suitable clocks setup

Creating Idle clocks one: To reach the normal idle clocks of the HD 4570 (Core: 110 MHz, Memory: 250 MHz) you will need to go to the power user tab because the minimums will be higher than the usual 2D clocks of the GPU and do the step in green color in the previous image (image 2) and save the profile

7- Now we have 3 profiles (Normal, Idle & OCed) and in order to make life easier we will make RivaTuner start automatically with windows and assign the 3 profiles to a launcher profile with 3 hot keys’ combinations to switch easily between profiles

a- Open launcher Tab in main RivaTuner Window
b- Choose Add new item
c- A popup menu will come up: choose Regular item
d- Do as shown in the image below (image 3) ( for me the normal clocks profile was named Normal power with hot key combination Alt + P)
e- Repeat the last step for the other 2 profiles



So now you have your HD 4570 OCed with 3 easy to control performance environments by just 3 key combinations you can choose the mode you like as a replacement to the lame ATI PowerPlay & Rivatuner lack of support to the GPU, also Acer users are now free from the 500 MHz memory bug, once again I tried to make this guide as easy & clear as I could so please if anything is not clear don't hesitate to ask.

Waiting for your comments and inquiries

 

Thanks for this. I was able to overclock my hd4570 to 850 core clock and 950 mem clock.

I am still confused as to how to set the idle clocks. I go into the power user tab and change the clocks to 110000 and 250000, but I don't know how you would save it.

In the beginning of your post, you wrote don't undervolt gpu under 1.2. How would you go about undervolting your gpu?

 

when u set the idle clocks you go back to the OCing tab and make a OCing profile with these clocks and save it so it will be your idle mode profile & windows start up one

if my memory serves me well .... I undervolted the GPU using AMD GPU tool

 

When I go into the overclocking tab after I set the idle clock, the clocks still say it is at 680/800. Though the windows startup up setting thing says "Startup setting: 110MHz/250MHz" When I try to save it, it saves it as 680/800.

When you say AMD GPU tool, do you mean AMD GPU Clock Tool? I tried that program but I can't do anything in it. I also tried ATI Tray Tools and ATI Tools. Nothing worked.

 

hmm.... strange behavior for me when I made the power user change went in and applied the settings and made the profile it stayed that way and booted with the 2D clocks try to check the startup clocks with GPU-Z

& yes I mean AMD GPU Clock Tool it actually gave me 3 Voltage solutions I think they were 1.2v & .95 and something in between

 

Hey,

I cannot get Rivatuner to work. I installed it do not understand the part where you said: "1- Download Riva Tuner (for windows 7 & vista 64x users you can get x64 Vista assigned drivers for Riva Tuner v2.23 and simply rename them an overwrite the 2.24 drivers with them and when installing Riva Tuner click yes on installing the available updates step after the installation is complete)"

where is this 64bit driver? I see a Rivatuner64.sys file in the rivatuner directory, but everytime i try ot start the program i get the "Cannot load RivaTuner64.sys driver" error.
I do have admin privileges enabled for Rivatuner to run.

more clarification appreciated

 

I figured out another way to set the idle clocks. Just go into the power user tab. Look for RivaTuber\Overclocking\Global. Set Min Clock Limit to 0. The min range for my clocks changed to 70/80 so I could just set the clocks from the overclocking tab.

 

http://www.techpowerup.com/downloads/Utilities/

you will find the drivers named as "RivaTuner x64 signed Drivers" when you download them rename them to the rivatuner 2.24 drivers name be default "RivaTuner224MSIMOA2009Edition" because these ones are made for rivatuner 2.23

copy them to the Rivatuner setup folder & replace the old ones and install rivatuner & when it asks you at the end of installation whether to install updates or not, make it install the updates

 

that was the idea all along .... but I wanted them to be set 110,250 because if you go below that you may experience crashes & errors ... some of the HD5000 series cards have serious problems due to their low 2D clocks .... so I would recommend not going below 110 on core & 250 on memory

 

I didn't say I set my clocks at 70/80, I was just saying the minimum clock speed I can set them to using the slider in the overclocking tab is 70/80. I have it running at 150/250 for idle right now.

 

How do you get to the page on image 3?
Never mind I sucesfully overclocked to 850/900 MHz

 

How exactly do u undervolt on AMD Gpu clock tools? i don find the option anywhere!

 

Any1 know wat is a good setup on catalyst control centre for cod4. Or should this be in another thread or topic

 

Greetings!

Just a little warning for people with the Aspire 5536G (HD 4570). I believe these computers have slower graphics memory (DDR2 @ 500 MHz). They clock down to 250 in 2d-mode. With PowerPlay Disabled I get 680/500.

And yes, I did find this out the hard way as I was following this guide and merilly OC-ing away, trying to hit 800 MHz on the memory. Bad idea. Rigth now I'm just happy I didn't cause any permanent harm to my poor PC.

 

wow ...... trying to hit 800 from 500 thats almost 40% increase ..... you should take it slow like 5 mhz increment and then testing and repeat & never try to go as extreme as OCing the memory by 40% because you cant check its temp.

I have a crappy GPU that can barely reach +50 mhz on the memory only :S .... quite unlucky because some people reach up to +100 mhz on the memory and it is still stable

EDIT: @Ollollo try to use Xtreme-G 10.5M Driver it will give u quite a nice pump in FPSs with no OCing

 

IIRC my 4570 reached over 900mhz on the core, but only has DDR2 so only did about 650mhz mem.

 

Why all this long method to oc the card?
Just install MSI Afterburner, go into the program folder, open the cfg and enable "unofficial overclock" or something like that.

I had an hp with a hd4550 switchable and in this way i was able to oc it with a gain of 20%.

 

you cant OC the HD 4570 in the 5738G with MSI afterburner because it has a bios bug

 

You can also flash the bios with the new clocks if you are happy they are stable.

 

I see, that sux really. Anyway happy ocing. I had a blast with that card and a mere i3 320m, played Crysis and Singularity alot with great framerates at 720p.

 

Mine OC with Core set to 800 & Memory set to 880. I haven't push the Core Clock too much yet. Too bad yours equipped with DDR2 memory only.

 

It is a pretty amazing GPU that can pull its weight compared to other low end cards

Thanks to Acer for integrating the GPU bios with the mobo bios you can't do any GPU bios modifications at all on a 5738G unless you miss with the laptop bios which I will never do

 

I want to undervolt (lower the voltage) my 4570. Can you advice which tools suitable for our card?

 

The AMD GPU tool for HD 5870 is the only tool that controls the voltage on the HD 4570 but it will make u only choose from the available card voltages which in my laptop are 0.95 volts & 1.2 volts

 

Yes, I wasnt even considering this an overclock, just trying to "get what was mine in the first place" - the 800 MHz. But of course, I was wrong

Thanks, will try!

 

i have a toshiba with the ati 4570 graphics card dd3.. i keep getting the "display driver stopped responding and has recovered".. tried so many fixes.. none of them worked.. now i found a possible solution to change the idle clock times
i found that i have to increase the idle clock freq.. now when i look in rivatunner the 3dCoreclk khz is set to 680000 and 3dmemclk khz is 800000. i haven;t made any changes with riva tunner yet. the default3dcore is 680000 and default 3dmem is 830000.
so can u give an advice on how to stop getting this error, what values should i insert ?

 

I B O W TO YOU, MahmoudDewy!!!
I thought my HD 4570 was bugged, because I even couldn't reach the default memory clock (800 MHz). I overclocked it to 750 (the max available). Now I can overclock to 1020 MHz! Just started a stability test with Furmark (1366x768, 4xAA) and will last about 30-35 min with 862 MHz GPU clock (it's the highest I've reached) and 849 MHz Memory clock. If I don't get in to trouble, I would increase little more the Memory clock (849 MHz is still in the middle of the safe zone, so... ). Thank you so much for this, I've looked and never found solve for this problem, but here YOU helped me! I appreciate it man!

The only bad thing I see now (20 minutes after start of Furmark) - my GPU temperature is 92 degrees. :S Should I enable the fan control and increase it to 100%? Or anything else I can do to lower the temp to 85-87 degrees? (I don't think my temp is fatal, but I want expert opinion ) Thanks in advance!

 

glad that I could help you man ..... as for the fan control unfortunately you can't do that ... but undervolting is a great option to reduce your laptop overall temp I do it on my laptop and my gpu runs around 80-85 max OCed and my processor around 55-65 max

here is the undervolting guide check it out and tell me about the results

http://forum.notebookreview.com/har...arket-upgrades/235824-undervolting-guide.html

 

I'm using this stuff already. Normal (without doing heavy things) my processor temp is under 40 degrees.
Btw, I increased the fan speed to 75%, increased the memory clock to 902 MHz and the temp don't go higher than 90 when Furmark is running. When playing WoW, the gpu temp is around 66-68, so I'll keep it like this for the moment.

Thanks for the fast reply!

 

Thats what I am here for .... any questions you have don't hesitate to ask

 

hey...thanks for this guide it helped a lot and on a totally unrelated issue what do you keep as the VID for 11x multiplier?

 

0.9375V .... I can do 0.925 but sometimes when it is stressed for long time I get BSOD so I keep it on 0.9375V

But take that with a grain of salt ... as processors are different so you can go much lower just try it

 

Yeah, but I have exact same notebook as you - Acer 5738G and are you sure it works properly at 0.9375? Its a big change, the default 11x VID is 1.15....... your 11x VID is closer to the 6x VID -0.925!

 

Exactly .... I know it is a huge drop but sometimes I play dragon age origins or GTA IV for 12 hours straight!!!! I don't think you need any more stress than that I have 3 multipliers on 0.9375 & the other 3 on 0.925 I think with the lower multipliers I can get even less but I have my voltage locked @ 0.925 and I tried several ways to unlock it but to no vain

 

Thanks a lot......I changed my Vid I've been running orthos stress test for about half an hour and the highest temp. till now is 65C which is a big difference from before!

 

and btw 12 hours straight??? Im no one to talk about taking a break (that would be hypocritical!) but Im pretty sure your going to have some serious problems with playing for that long...........

 

I have a work/study overload issues so when I take a break it is a looooooooooooooong gaming break so these 12 hours sessions are like months apart but still they count

 

Is it possible to overclock the cpu of 5738?

 

I used a modded bios to unlock the EIST option to try to overclock it using the IDA method but it didn't work, even with EIST off you still can't overclock it :S
as for SetFSB it is impossible to overclock it too according to SetFSB maker so if you managed to find another way I am brave enough to give it a shot

 

How about clockgen or some other software overclocking? I'd really like a few more FPS in my games...after all we 15 year olds need our gaming damnit!!!!

 

lol .... I don't think pumping the processor to 2.4 GHz will give you any fps because the HD4570 is already bottlenecking in most of the games which aren't CPU demanding

 

I see anyway thanks for the info!

 

I was stress testing my 4570 today and I noticed that the fan speed was ALWAYS 30% on GPU-Z. Is this false reading from GPU-Z or is there a prob with the fan??

 

The GPU doesn't have a dedicated fan it shares the fan with the processor .... so that 30% is a default reading of a non existent fan for all the ATI GPUs which have no dedicated fan
