I did a hardmod but have not tried flashing yet. I am still investigating what will work when I have time. I don't think there is any bios that you can just do a straight flash to.

Here is a question, If ATI actually disabled pipes why was it done? They had the chance to build an even faster card but they decided not too. Why did they do that, the card was build for a gaming laptop. Also having more aggressive bios would be nicer but that would mean less of an overclock.

Here is what a guy posted about his X800SE

Here is my result with 3DMark2003

I had it oc'd to 550/550. Its stable at these speeds.

Answer: Designed obsolescence.

My parents had a refridgerator they received as a wedding present in the mid 1950s. It was serviced once in the early 1960s to fix the motor. They only stopped using it when they moved to Florida in the 1990s because they did not need a 2nd refridgerator. It is still working.

Everything nowadays is designed to last only so long - desgined to fail.

Companies don't want you to buy something that will last 40 years. They want it to last just long enough for you to buy the next generation of it.

Many companies will build the ultimate widget. They will step back and review its product life cycle. Then they will strip features from the widget so that they can introduce them as a series of upgrades - thereby extending the product life cycle by 'n' months/years.

Everybody wants to have "the latest and greatest" cell phone/car/laptop.

Give them what they want - while at the same time reducing product development costs by not inventing 5 versions of the widget.

reclun,

How did you hardmod your MR9800 and which jump did you make? The laser cut could be stopping the path of the top or bottom curcuit. Correct me if I am wrong, because I am not fully aware of the pcb schematics.

The jump I made is vertical on the right hand side where the laser cut is in the picture I posted. Make sure you are looking closely at the picture and understand where the cut is. I might have time to modify the picture this evening and put an arrow pointing at the cut. Look at post #7, it gives a nice closeup of that area of the pcb.

reclun,

Have you totally loaded a modded or mobility x800 bios, and did you use solder to make the jump?

I used a conductive pen to make the jump. I have not tried a bios yet. I am still investigating what might work.

wardo,
send me your pics and I will post them. my mail is:

Lets see them Pics.

The major problem in trying to unlock theses pipes is we have no bios to work with. For instace, there are four versions of the X800 that have a different set of bios for each card. The one good thing about the X800's are that you can flash any of the bios to each card.

Maybe someone can work with this. For the X800 Pro you can flash modified X800 Pro bios that will run with the 16pipes open while keeping it the same card it is, it's basically modified Pro bios that have the extra pipes unlocked. Maybe someone can look at the regular X800 Pro bios and compare them to the X800 Pro bios with the 16 pipes open, then apply the same changes to the bios to the 9800?


Here are the 16pipe pro bios

Here are the normal 12pipe pro bios

according to http://www.beyond3d.com/previews/ati/m18/ the mr9800 is a R420 core with only 4 pipes disabled allowing up to a total of 6 vertex pipes and 12 total pixel pipes. This means (I think) that it is a modified R420 core instead of having a x800xt 16 pipes available, there is only a total of 12 pipes available.

Explains why it overclocks so well

My X800Pro used to be 475/450, now its at 520/560. My core has went up to 570mhz but my memory finds an error at about 567

K4D55323QF-GC22 450MHz < anyone that can OC to this clock verify what ram they have?

K4D55323QF-GC25 400MHz < anyone that can OC to this clock very what ram they have?

K4D55323QF-GC2A 350MHz Thats the one this pic has


K4D55323QF-GC33 300MHz

K4D55323QF-GC36 275MHz

How come Everest can't determine what memory I have?

I am very sceptisc to this unlocking. It seems very hard. But if it's possible, there will be dramatic change in fps! Hope so atleast...

btw... I thought M18 had 110 mill. transistors.

I haven't seen yet a program that can tell if the card has GDDR3. Even latest RivaTuner says I have "256MB DDR" on my desktop's GF6800GT - but actually it is DDR3 1000MHz.

Keep in mind that the R420 can accomodate both DDR and GDDR.

I would like to know how the mobility x800 has configured on the pcb for the disabling of 6 pipes. If in fact the pcb is the area where the disabling occurs. I am looking for dell picture of these cores to compare to MR9800.
