Overclocking Quadro NVS 130m?

Hi all,

I am thinking of buying a notebook with a quadro nvs 130m graphics card.
I heard it's based on the 8400M?

And the 8400m GPUs were faulty:

So will the same thing happen to the nvs 130m?
And would it be safe to overclock the nvs 130m?

I wouldn't overclock if it's likely to be faulty like the 8400 cards.
But if it's fine, which software would be recommended?

 

If it is based off of the 8400, then yes it will have the same potential for problems.

 

I was afraid of that

This notebook comes with no warrenty, I'm not sure if I should buy it.

Does anyone know what exactly goes wrong with the 8400m GPUs?
Is it that the solder cracks?
Is this the kind of thing that can be fixed by heating up the solder?

 

It has to do with the packaging, yes. Reheating it *may* solve the problem for a while, but it is very risky and from what I have read the long term survival rate of the computer is still low even after that kind of "repair."

Without an official warranty, I would definitely stay clear.

 

I wasn't going to buy it, but it was a really nice price on ebay (~$200).

So now I have another tecra:
T9300 2.5ghz
512mb ram (will definalty upgrade to 4gb)
quadro NVS 130m.


Now I read about the GPU, and it has the G86 core.
It seems that is the faulty Nvidia core:

And since I'm not willing to try to fix it if it goes bad, I will just sell this notebook.

Unless someone can confirm that if I give this thing some really good cooling, it will be ok to overclock?

And here is a dumb question, I remember reading on some website a long time ago that someone used a hair dryer to remove a CPU that was soldered onto a motherboard. So could a hair dryer have enough power to fix this graphics card (melt the solder)?

 

I got a 8400m GS (G86 core) and can overclock at nearly +50% clocks, its still alive and its nearly 2 years old.

But keep in mind i did the copper mod and always keep the max temps below 75c. A normal 8400m gs (using stock thermal pad) would hit over 100c max, which made them fail prematurely.

I still do believe that all 7xxx & 8xxx series are defective due to the weaker solder they used. You can make it live longer by keeping it cool.

Though that isnt always the case, my 7200GO died after several months and i never even overclocked it. It just died and kept beeping one morning, the only way i could get it back to life was to cover the exhaust vent and overheat it. (similar to reflow technique)

For $200 i still think thats a good deal if you dont overclock. Seeing as if it fails, you can just strip it down and sell the CPU, RAM, WIFI,HDD and other parts to get back your $200. I suggest you inspect it first though.

 

Yes, I will inspect it when I get it.

The notebook had been dropped and the seller said the screen worked for a few days and now doesn't.
I think it should be simple to fix, I also have a toshiba parts place so that I can get any part I need.

The CPU in this notebook should be worth ~$200, so at least I can get my money back as you said.

BTW, this is AUD not USD so I got the notebook pretty cheap


EDIT: Also, did you see a big performence gain when you overclocked the 8400m GS?

 

I wouldnt say big, but significant. It definitely helped me crank the settings higher on source games

Do you know how much vRAM it has? DDR2 DDR3?

 

I think it's 128MB DDR.

EDIT:The 8400 has GDDR3 doesn't it, so maybe the NVS has the same, I'm not really sure.

 

Would it be possible to turn the NVS 130m into a 8400m?

Sort of the opposite of this:

I think it should give better gaming performence?

 

I found an interesting thread:
http://forums.laptopvideo2go.com/topic/18776-nvidia-8400m-gs-modding/

Makes me think it's possible to change the NVS 130m memory bus to a 128 bit bus width.

 

I tried the mod and my bus is still only 64bit.

But I did manage a good overclock. I went from 400/600 to 661/815.
Max temp was 60 but is now 70.

By the way, I'm using a refurbished motherboard which looks to have had the BGA reballing done on the GPU. So I wonder how long this will last.
