FireGL - max overclocks?

Hi chaps,

Just wondering what your max overclock if with the fireGL T2 128mb?

I tried 415 // 270 and it was rock solid!! My temps for CPU and GPU were around 65c after a benchmark.

Another question - are there any better fan control programs than tpfancontrol? Because mine keeps crashing in smart mode (does with no overclocking too)

Thanks

Hi,

A fireGL T2 is basically like a 9600 with more memory. These mobile chips overclock quite well. My mobility 9600 do also overclock to that levels... but be aware of heat.

Heat is the real danger and for your numbers it may be very well that you are not measuring temps properly. Note that the graphics chip does cool off *very quickly*. This means that it could be overheating and just 3 seconds later be at around 65ºC ... so it is not *after* the benchmark that you should look at temps, but *during* benchmark Now, how to do this when the benchmark is fullscreen and no way to look at fancontrol or NHC ? Not easy. Basically, change to a windowed benchmark for GPUs, such as ATITOOL or ati tray tools heating / 3D exercisers so that you can monitor temps at the same time. Otherwise, you run the risk of ruining your TP.

I will try the atitool heat up tonight.. What do 9600's run at in the desktop versions?

There are no artifacts at all either, and the heat coming out of the side of the TP from the fan is fine.

What do you clock yours at? I get 11k 3dmarks now which is good. I've just ordered company of heros so i'm wondering if the TP can tackle this

How could I not measure temps properly? Max fancontrol temps reached after the benchmark is 65c (it specifically tells you the peak temp), this is probably just the CPU though.

Hi

How could I not measure temps properly? ...

I was meaning that you did not measure meaningful data because most probably the GPU had enough seconds to cool down (1-2 seconds is enough). This is because a *good* 9600 or T2 will easily reach 80ºC-90ºC in a 3D load test, so reporting 65ºC after the test does not tell much at all. Another thing are the radeon 7500s ... those do not heat up that much at all.

9600s are clocked in T42s to run at 320 (GPU) / 210 (Mem) default without powerplay. I can easily overclock mine to about 420 / 245.
stable, but have set 400/230 as my 'hi speed overclock' in NHC for gaming after working a bit on the cooling solution and making sure it will never exceed 85ºCat full load. In fact I have now 2 T4x with 9600s (after I replaced the motherboard in my T40 for a T42-M10 one) and both reach very similar levels.

i see! I will let you know the results tonight! I've heard people getting 450 core stable!

In the desktop version (passively cooled) isn't the clock 400/350?

I don't plan to overclock my fire GL T2 - but to the temperature thing - the R50p doesn' come with the long fan originally, only separated passive cooling, and it shutted down with the original coller, when playing far cry in the bed, and the GPU temperature I noticed just before the crash was about 116°C... So now with the T43p long fan, maximum load temperature is between 85-90, the highest temperature i noticed was about 86°C, but as noticed here, the GPU cools down really quick, when I switch back to windows to check the temperature from the game I play, it drops from 85 to 75 in a few second...

just tested it intesively @ 405/240 and temps were 88c with atitool running for 10mins!

I'm happy with that:)

That's about right. I got max temp of 84 (overclocked) after some work on the heatsink w/thermal paste,... besides, yours is a fireGL/T2 and it has more memory-> potential for some added heat.

Now it's up to you to decide what temps you consider 'safe'. In any case I would say anything under 90-95ºC is OK for these ATI GPUs.

cool, what did you do to the heatsink though as i dont think the pad on the gpu is very good, but the heatsink won't touch the core without it.

Well, I was going through similar trouble, I got the T43p long fan brand new, even with original thermal paste for CPU and thermal pad for GPU. I removed both and applied arctic silver 5 instead on both places, and I don't think the fan is not touching the GPU, as the temperature is above 85°C only in bed where the fan has to do much harder job than on the flat table, and it is not exceeding 90°C (Which was common with the original, well settled but only passive cooler) whatever I do. So I don't know what thinkpad do you have, but with my R50p I really don't miss the GPU thermal pad.

Well, in the first machine I inserted a very think copper sheet which I did cut to the size. Similar to the one already in the heatsink (where the pad usually touches).

For the second machine, I attempted the same, but the available sheet was then a little bit thicker and this prevented the CPU to contact with enough pressure the sink so results were not satisfactory even if GPU was very cool, so I ended bending the GPU part of the sink 'just a bit' and not adding anything other than thermal paste.. and results were good also.

This is interesting, because I didn't do anything to the GPU part of the fan, just removed the thermal pad and applied thermal paste instead. Can you post here what is your idle and full load temperature on both machines and what fan are you using?

I have no problems getting the core to 450 MHz on the Mobility Radeon 9600. If you do a undervolt at the same time, total heat output is lower than standard CPU voltage and standard GPU clocks.

Hi, mi idle temp is of around 50ºC (CPU), 53-54ºC (GPU).
My load temp when running CPU intensive tests is 63-66ºC for the CPU, and usually3-4 ºC LESS for GPU.
When the benchmark is GPU intensive then my GPU temps get as high as 81-82ºC non overclocked, 85-86ºC when GPU is overclocked. CPU in this case can go as high as 70ºC.

(Remember this is w/a Dothan running at 2.0GHZ, and the 9600 M10). My fan is the long M10 fan for one machine, and the long M24 for the other.

This seems comparable, I'm getting CPU above 70 and GPU above 85 at full load (To be concrete - when playing far cry), but I also have the 1,7 banias, which may be more hot than any dothan CPU.

And which program do you guys use to overclock the GPU?

I'd like to try that in my T43p.

amdaman · #18 Post by **amdaman** » Sun Apr 06, 2008 9:16 am

I used ATI tool, that 3d view it uses really stresses the GPU to check stability.

I'm getting 11880 3d marks now with the normal catalyst drivers, they are far better.
