Only try this if you know what you are doing!
I've realized something...
This will only work if you have really good cooling pads. Ones so good, your pc will run very cool.
Go ahead and overclock your x1900/x1800. It's a free overclock.
I'm crazy, hum? The cards will die, hum?
Nope, they will live JUST AS LONG as you normally bought them, provided you have substantial cooling.
Now what am I talking about?
When these cards went into production, their factory core clock speeds and memory clocks speeds were set at a much higher output then what the companies set them too.
Because the cards generate too much heat. But if you can find a great cooling pad...
Here's the thing, my x1800 was set at 350 core, 425 memory. Yet it's REAL core speed is 450, and memory speed is 500.
I found this out by using either ATI Tool or ATI Tray Tools.
Neither of these will let you overclock a mobility card, but go ahead and run them. See if they show a greater factory clock speed then 400 core, 470 memory for the x1900.
Post your findings, and then everyone with a x1900 can use powerstrip for it.
For x1800 users, just set your clocks in powerstrip to 450 core, 500 memory.
Now why do this? Wouldn't this kill the card? No, because overclocking kills because you set a card beyond what it should be set.
These cards were set below what the factory settings are.
If you set them back, you aren't setting above factory settings, you are simply 'making it right'.
The only problem is, of course, heat. If you must take it somewhere, set it back to underclocked settings.
This will give you a huge boost to your pc power unless you do something stupid, like not use a cooling pad and kill your machine.
I'm modifying this slightly because some people don't understand what I mean. While it wouldn't kill your machine, it also would. Increased heat would kill your machine, which is why I said a very good cooling pad.
You aren't going over the threshold of clock speeds given, or some kind of possible threshold that clocks can only go to, but when more heat gets added to a small area, it can kill faster.
If you want to try this, be careful. May be best to use artic silver.
If it works though, you'll end up with a fast machine that won't die.

Strange post... Well anyway, in Fujitsu-Siemens the x1800 and x1900 have both the same clockspeeds: core 398 Mhz and mem 468 Mhz. They are both underclocked. Still I wouldn't encourage people to overclock unless they really need the extra performance. The cards are underclocked for a reason. Here's some info about x1900 overclockability (see post #114).

This doesnt apply only to the x1800 and x1900. Many if not most GPUs in laptops are underclocked by the manufacturer.
-
Can you post the difference in temp and power consumption (or battery life) ?
You can always overclock but it comes at a price,see the TDP of 7800GTX when on full clock (many people chose to overclock their underclocked E1705's - when it had 7800 too but...) *points at siggy*
Sometimes the design of the cooling system of the laptop will not allow higher TDP's, so overclocking comes with it's risks too. -
Is the point of this thread to say that you can OC an X1800 or X1900?
Aside from that being very old news, it should also be noted that the X1800 in particular had to be underclocked in most of the notebooks it's installed in because of the heating issues you mentioned. And as mentioned by wave, most laptop GPU's are underclocked to begin with anyway. -
ati Tray Tools CAN overclock these cards. Works with my x1800. And ive ´reclocked´ it to stock ATi and played oblivion for hours with no hear issues or artefacts. no cooling pad used.
I suspect it is underclocked for battery time and noise rather than getting too hot for the cooling.
but powerstrip is a great piece of software. -
-
x1800s really shouldn't be overclocked and to a certain extent neither should x1900s. They are already hot as hell.
You don't need a cooling pad as a must though. -

I don't really believe in the concept of a GPU being underclocked in a laptop. GPUs are clocked by the manufacturers based on the thermal profile and power characteristics of the system they are designing. While GPUs may be clocked differently between two different models, that's not necessarily because one manufacturer is skimping, it's just that the design is different. I'm pretty sure what ATI defines is the maximum clock speed that ATI continues to support under their warranty. Anything over that, then the manufacturers have to cover the costs themselves. While a chip may not necessarily be underclocked depending on the thermal requirements, it can be overclocked since there is no way to judge if the design has sufficient cooling to operate the chip reliably. Using a cooling pad kind of skirts this of course, but it's still shouldn't be for everyone.

Yes, it was a strange post.
All it was meant to say was, if you overclock, all you are doing is setting the clocks back to their speed, but if you do so, do it at your risk, with a good cooling pad.
If you find you have the ability to do so though, it's not going to kill your pc. -
If you look closely enough, you'll find the companies define the max clock speeds by a different number then what they are clocked. -
Which sensible manufacturer wouldn't like the performance of their laptops to get higher for free when the competition is this close ?
BTW,Zellio you really are the god of double-posting. -

Is this the technical limitations too?
Because if you would like to say that, I have many a desktop person who would love to prove you wrong, with their overclocks.
Don't speak before you know something. -
The things I posted were all about laptops.No desktops.
Heat and Power Consumption are almost of no importance when it's compared to laptops. -
LOL, I see, so it's alot different for laptops.
You mean if if you overclock it too much it may kill your power supply?
Or get unstable?
So what your really saying is that it's different from what happens to desktops when they get overclocked to much?
Because, when they get overclocked, they may kill the power supply, or become unstable...
The main problem is, I've known people who have pushed it over these 'thresholds' as you call them, and continue to have stable pcs and good power.
They pushed it petty far. -
What you are saying is : "Since ATI said this chip can be clocked at X if any manufacturer dares to underclock it,they are ignorant and their users should hurry and overclock their GPU's"
What I am saying is : "The manufacturer has a really good reason to underclock their GPU - mainly to lower the heat and wear - and many people choose to overclock because they want to suck all the juice out of their GPU, but it's not for free, increased heat, possible damage to internal components and the internal parts getting worn faster all should be taken into account.Although you can decrease the heat and the risks by measures such as different paste and cooling pads." -
And nice double take. You said that is the threshold. I can prove people can go higher then those clock speeds, even with my own clocks and temps, with are 10 clock speed higher.
I never said this was totally safe. I never said to rush out and do it, which is why I said you could do something stupid. I said you needed a cooling pad.
What I did say, is that if it cools correctly, you'll end up with a machine that runs fast, runs cool, and runs at the factory clock speeds, without dying on you quick like a desktop machine would if overclocked.
But you do make sort of a point. I did word the whole thing wrong. I don't know how to properly adjust it.
This thing should be more the people who know what they are doing. -
*sigh* -
Quotes don't help really.

I agree with ronkotus, you guys amuse me.
@Zellio: the mobility x1900 is most likely based on the x1950gt/x1950pro (rv570), cause they have the same die process - 80nm - and same shader config, but clocked lower.
OT@mujtaba: How's the weather in Tehran? My friends gone back to visit, and I just wanna see if it's warmer here (cause it's summer-ish here) -
@Zellio:You are doing as alway,first you try to get all the attention you can by telling people something "special" but sadly,you don't have the competing skills either.So you turn the rest of your posts into a flurry of personal attacks to anyone who disagrees with you.
Now, to weather : The sky is clear, it's just a bit cold here. -

I think this thread has served it's purpose, if indeed there was one.
Everyone with an x1800 and x1900, READ
