Pin mod question

I not sure if you can pin mode the 2.0 the highest I have seen is the 1.8 being pin modded, and not all of them are successful.

I am interested in this question also. I have a 2.0 in my 9200 and would like to know if it could safely be done when I upgrade to a 9300 in a few weeks.

No you cant pinmod a 2.0 well you can try, but it will crash your system good.

It was tried a while ago by a forum member named Lucious I believe. He was not sucessful even with volt mods. He was able to hit 2.56 GHz stable (using RMclock) but not 2.66 GHz. Chances are there's a few 755's out there that could do it (with volt mods) but good luck finding one of those golden ones.

Any PIN mod above 1.8 would be fairly unstable and often time not bootable. You pretty much have to get some good heat sink on those baby.

1.6 => 2.13 very stable
1.7 => 2.26 get pretty stable.
1.8 => 2.4? 50/50 chance stable

With the right combinations of pins it should be possible. You may have to short pins elsewhere on the chip to achieve higher voltages or the notebook may not boot. Even if you do attain the speed heat will be a major concern.

I still have confidence that it can be done. It would involve as you said, finding the right chip. I could have also gone a lot farther with the cooling. The bottom of the heat sink had more imperfections than the surface of the moon. If you were to lap the heatsink it might run stable. A forum member by the name of HKPolice is trying that as I speak.

The speed of the fan could also be upped via a bios hack or workaround. In my GPU overclocking adventures I stumbled upon the Fn-R combination that brought up the fan speed control bios page. It only works when you have a heavy load on the GPU, and intermittantly at that. This allows you to set the fan speed higher than you can with tools like i9kfangui or the like. The problem is, your bios will NEVER set your fan that high automatically.

I can tell everyone that the system IS bootable and benchable as long as a volt mod is used. It will not POST at stock voltage.

I can also tell everyone that these laptops (9300s and xps2) are some of the easiest to take apart and put back together that I have ever seen. I must have taken mine apart at least 25 times trying to get the right wires in the right socket. I did misplace my wire once and grounded something completely different... it just didn't boot. I fired it up a few times without tightening the screw to secure the chip in place... no problem it just didn't boot. Freaked me out at first though.

My advice to anyone who wants to try a volt mod - If you want a near sure thing, go for the 1.7. If you want to tinker at the risk of it not working, go with a 1.8 or a 2.0. If it doesnt work you can always sell it. The fact that mine still works is enough for me to say that most people won't do any permanant damage by trying.

Oh and btw my name is lucidchaos. You were close though

I'm pretty sure I had heat problems with vid4, 2, and 1 grounded. My temp hit 82* C. Prime was going along nicely for about ... well I really don't remember, maybe a half hour or so... and rather than an error, it just stopped. With lower voltages, it gave me an error. I figure when I get to the point of the computer locking up rather than erroring, the problem is probably too much heat.

This may or may not be dangerous, but it was outside my realm of comfort. The biggest problem is, when the system did lock up, the fan was still running on high and kicking out really hot air. It would have done that all night if I were stress testing. I don't really think it would cause permanant damage to the chip, but it still doesn't sound too safe.

On the other hand, the intel spec sheet does say that thermal shutdown is initiated at 125* celcius. and anything above that "may cause damage to the chip". This makes me wonder how much heat these chips really can take before being damaged. I think of it this way: the pentium M's thermal spec is 100*. AMD has chips with a thermal spec of 70*. And the overclockers are pushing the AMD chips to mid to high 60's and running stable. Am I naive to think that intel is exagerating the thermal spec?
