Clevo P151HM1 with 560m - Upgrading to 660m issue

Hi Guys,

Looking for some guidance/assistance. I bought a second hand card from Ebay from a guy who claimed he got it out of his working clevo p150em.

There is no brand on it that I can see. But on the card and in bios it shows vbios revision 80.07.2c.00.12 which on techpowerup website is a asus brand?

When installed the laptop boots up but gets stuck on the BIOS load screen where it does the tests and shows the CPU and memory. If i am quick enough i can get it to boot into the bios.

In bios it shows my vga card as Empty but reads the vbios revision and build date as 05/11/12.

my mobo bios is 1.01.14 and KBC/EC Firmware is 1.00.13

The PCB is blue where as my 560m is green. It is odd that it doesn't work as online there are many threads that say my p151hm1 can support up to 680m and 7970m provided with the right power supply.

I just wonder if it is a faulty card..

Is the card not the right brand or does it have the wrong vbios?

Cheers

 

The 660M was not really deserving of the 6 middle number and going from 560->660 is not really required anyway.

Can you show a picture of the card?

 

I dont think Asus makes a removable 660m. I think the blue PCB also designates it as a Dell 660m?

If that's true you should return it claiming it was not as advertised.

I also agree with Meaker, you can overclock a 560m very close to a 660m so unless your 560m died, it's not really worth it. (even then you might spend a little more and go 670mx).

 

Hi Guys,

Thanks for the help. I do agree going from 560m to 660m is not fully worth it but I did get it for cheap. ~$100.
Problem is my laptop only has 120w adapter and i wanted to do a mxm upgrade for the first time (i find it interesting).
The 660m is <75w while the 560m is 75w. So it should mean that i'll have more headroom to overclock the 660m.

I've seen posts by people getting overclock 3dmark11 GPU PScores of 3000 while 560m overclock only gets about 2400 pscores. Simply put the 28nm has more headroom than the 40nm even though it is only 128bit.

You might try blind-flashing a stock Clevo 660m vbios but that might just brick the card. If it really is a Dell card, you should probably go ahead and return it. Most people that try to use a different vendor end up with a lot of BSOD's and strange issues and IMO it's not really worth the headache.

Maybe it was only 100$ for a reason however.

Edit: Actually, didn't Dell block overclocking and overvolting their 660m? I think Dell users then took the Asus vbios to allow it? Or am I hallucinating?

 

That's a clevo card, it's from a P151em, you can tell by the code on it.

Typically the HM series has had issues with kepler cards other than the 680M with the first release bios files, later cards like the 675MX and later bios files for the 680M seemed to introduce issues.
