Ok, thank you for reply. So the 580 is equivalent to the 675 and I need the 675 VBIOS for EM-Series Laptops?

So in the P150HM it should work with 580M VBIOS...?

I told my friend, he can bring me the laptop so I can replace the card. I will post the results ;-)

Hello,

I bought a GTX 580M for a P150HM, that I sold to a friend. Now I'm testing it with my P150EM. The 580M came with Alienware VBIOS. I modified the nvdmi, to install the driver and yes, it works, but: I think, I don't have the full power. Windows Experience Index only shows 6.6; if I run Assassin's Creed IV, I have verry low FPS, Nvidia Inspecor says the temperature is just 48°C and the system's power consumption is only 110W. And Nvidia's system panel crashes...

I flashed a clevo VBIOS (VGA Bios Collection: Clevo GTX 580M 2048 MB | techPowerUp) on the card, but same results.

Have anyone here ever used a 580M in a P150EM?

Do you think, this problems will be solved in P150HM?

What is your Windows Experience Index with GTX 580M?

Thanks.

I got the Quadro K5000, so the GDDR5 should support it... I'm not sure, which component controls the ECC. Is it the GPU it's self or the CPU?

Because I think, mobile CPUs does not support ECC (ARK | Intel® Core). I'd need an Intel Xeon CPU therefore.

Hello,

when I try to enable ECC, I get the following message:

"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" -e 1

ECC features not supported for GPU 0000:01:00.0.

Treating as warning and moving on.

All done.

My Laptop: Clevo P150EM, Quadro K5000M, VBIOS: 80.04.33.00.35.

I tought, this error might mean the Intel HD Graphics, because running nvidia-smi without specifying a special device-id will affect all gpus (don't know, if that means all gpus or all Nvidia gpus). But after restart, devicequery.exe still shows:

I think, with my current VBIOS, ECC will not work. Does anyone here get it work?

The Problem is: It IS there! P150EM cannot disable Optimus, so I have all the disadvantages without lower powerconsumption :-(

P150HM needed 25-30W on idle, P150EM 35-40W (Same GPU), because the Intel GPU is now consuming power, too. If I had a OP-enabled VBIOS, I could at least have the 17W idle power as a benefit...

I can see 3 pros in Optimus:

- lower Power on idle (what means no fan noise from the GPU, too)

- support of Wireless Display (OK, I consider WiDi as unsecure and have never seen a display, that supports it)

- no need of blind-flashing GPUs, because Optimus-Systems will boot and supply the screen even with wrong VBIOS

( - finally the livetime of the expensive GPU may increase a little bit if it is off, most of time)

But there are a lot of cons:

- IF the Nvidia GPU is on, the System needs 10-20W MORE power (My problem...)

- Maximum screen resolution and color depth are limited

- No support of 120Hz/3D TVplay (Intel says the IHD-graphics got their own 3D-technology (InTru), but I could never get it work)

- IHD-graphics can just handle two Displays (Maybe newer IHDs can handle more... I'm not sure)

- FPS-Bugs when some programs use the Nvidia GPU and some other don't or if the IHD-Chip is decoding Videos

- No possibility, to let a program running on the Nvidia GPU if the power supply is attached and on the IHD, if the laptop runs on akku

- The OS have to load both drivers on startup

If I forgot something, please complete it.

In fact I got all the cons with my current VBIOS but no of the real pros.

Hello,

does anyone here use the K5000M in a Clevo P150EM? I have a (I think) Dell Precision M6700 VBIOS on it (Version 80.04.33.00.35) and I have one problem: Optimus does not work. The GPU doesn't turn off on idle, so I have to "suffer" all the disadvantages of Optimus without having lower powerconsumption... I think, my VBIOS is Optimus-disabled, because I used it in P150HM before.

So which VBIOS works best for P150EM?

Thanks.
