T400 ATI 3470 clockspeed?

I seem to be having a problem with my t400. I first noticed that games I should be able to play flawlessly weren't actually running very well at all. I soon sought out a way to figure out how my GPU was running, and to my surprise, I found this... ( refer to jpegs) My video card is downclocked by HALF?!?!?!?!? It should be running at 680/800, but it's not anywhere near that!

Now here is a little background. I first ran the machine with a clean install of Vista 64 Ultimate, I didn't like the performance so I went for XP which has been EXCELENT (gained an extra hour of battery life)!

With vista I was using the drivers provided by Lenovo, but since the swap over to XP i've been using modded 8.11 drivers, which I thought would change the effects of the downclocked card. (I had this issue in vista aswell)

Currently, I have PowerPlay off in vista control panel and I have the PowerManager set to Maximum Performance, which in theory shouldn't do any downclocking of any sort.

My question is, has anyone else had this problem? It seems to be that my system is suffering badly because of this... Downclocked video card by half is pretty huge...

Any help on this matter is greatly appreciated!

OPish

 

Have you tried running a 3D application and letting RivaTuner watch the clockspeeds to see if they go back up? PowerPlay could be malfunctioning even though you turned it off. Just a thought.

-J.B.

 

Yes, I've tested it all. no dice = /

 

Hmm...if it helps, my stats are attached below. It does look like the card is running at half the speed and the default clock and GPU clock speeds are reversed as well.

Also, I logged my speeds while running Fallout 3 and not once did the clock speeds exceed 337/396. So either those are the actual clock speeds we're supposed to be getting, or my T400's actual performance is being limited in the same way as well.

 

The same problem here. Does anyone have the solution?

 

wait, OP has GPU clock at 337/396 using gpu-z ver 2.8
eney, you have GPU clock at 680/800 using gpu-z ver 3.0 (which I also have)

is this an issue with GPU-Z? anybody know what kind of 3dmark scores this card should get?

thanks

 

Ahoy has used 2.8 version of gpu-z, and the results are same as 3.0.
as for the 3dmark you can watch it here http://www.notebookreview.com/default.asp?newsID=4569&review=Lenovo+ThinkPad+T400

 

i'm getting a score of 2549 which seems inline with the review (I have 2.4 p8600 vs review's 2.8 t9600)

take a look at the screen shots, 2.8 values are swapped when compared to 3.0

 

on notebookcheck Sony Vaio VGN-FW11M P8400, Mobility Radeon HD 3470 has 3dMard score 4865 http://www.notebookcheck.net/Review-Sony-Vaio-VGN-FW11M-Notebook.10735.0.html

i think it means that on t400 its underclocked

 

I used 3dmark06 for that score, not 05

 

the scores I got and in the review seem inline with this link

http://www.notebookcheck.net/ATI-Mobility-Radeon-HD-3470.9594.0.html

 

ok.
so is ati 3470 on t400 underclocked or not? if it is, how can I clock this card to its normal state?
And would it be safe?

 

i really cant tell. the scores SEEM ok but I am not happy about gpu-z under reporting (i think)

I have tried to overclock with ati and amd tools. neither work.

I think we will have to let lenovo know about this

 

batman5315 look here: http://forum.notebookreview.com/showthread.php?t=272669&page=132#1315
on sony sr with ati 3470 clock and memory speed are ok

 

eney,

it seems lenovo has underclocked the card then. just to be sure, can you find out what the 3dmark06 score is on that sony?

thanks

 

Here's something I would try.

Connect your computer to an external monitor, so that you have 2 displays.

Move GPU-z onto the second display.

Fire up a 3d game (Left4Dead) on your main monitor and see if gpu-z records a different clock speed now.

I know for a fact that video cards downclock in 2d mode. Even if you have a 3d application running, when you alt-tab to look at gpu-z, it will revert immediately to 2d clocks.

After my class I will give above a try and report back.

 

raxen,
you can also use 'log to file' function in gpu-z
choose sensor tab -> and check 'log in to file' check box.
i played Grid on highest settings and then looked into log file,
cpu clock and memory clock stayed all the time on 337/396

batman5315,
on sony subforum you can see that sr has 2041-2089 marks in 3dmark06

 

You're right. I just tried exporting to the log file and I saw no change when I started Left4Dead.

I will get back to everyone about the dual monitor method, but it doesn't seem to be looking good.

Lets just hope GPU-Z can't read the clockspeeds properly, and it isn't an ATI driver bug (which sadly they are known for...)

 

Ok so our 3dmark06 scores are on par with what we would expect.

I'm guessing that its just bug reporting incorrect clock speeds. We seem to be getting good 3dmark06 scores regardless of the incorrect clock

I will begin pestering lenovo when I free up some more time. I suggest all of us here do the same in order to get the message across that we are all experiencing this problem and its not just a few isolated units.

thanks eney

 

My GPU z is showing the same thing...could it be immature drivers?

 

StealthTH

we don't know jet. but it looks like its some problem with GPU z as 3dmark06 scores are ok.

 

Using GPUZ 0.30. The main page shows 680/800, but the Sensors read 337/396. I tried running something 3D intensive (I think I did, don't remember, lol), and it didn't change speeds. Tried to underclock with AMD tool, but it gave abnormal numbers.

 

I get the same ATI issue with GPU-Z 0.30 on my T400 as well.

 

Hi,sorry for reviving such an old thread...

I am experiencing the same problem asmany of you with the HD3470...
The main page shows 680/800, but the Sensors read 337/396.... So,I guess the card isn't giving it's full potential.

Did anyone find the solution to this?


PS:Sorry for my bad english...I'm from Uruguay

 

Im experiencing the same thing. I tried TF2 and the difference between the integrated and 3470 are about 10fps.

I saw a other thread here on NBR where the average FPS were 40fps Im getting around 25 in average with the same settings. :/

 

I am also experiencing this, GPU-z is reporting the low clock speed. and AMD GPU clock tool does not work for me to set a new clock speed. But it does say current clock is 730mhz? I think the tool is reporting it wrong. I am using vista 64bit.

edit: oops, didn't see the other thread about this issue, guess AMD GPU clock was known not to work. Hope someone else comes up with a solution soon
