Qiweiyu11 is using a sandy bridge cpu. They only support 2.0. I'm still leaning towards and OS reinstall to be required to fix this. Windows is garbage like that.

That warning means nothing in your case. Flash away. Have you tried reinstalling directx? https://www.microsoft.com/en-us/download/details.aspx?id=8109

Another update. I put a fresh install on a wiped hard drive. Performance was improved to match win7, but I still had the same fps capping problem. Win10 has since been removed. No DX12 for me.

We really needed AMD to make a stronger comeback this gen. We're going to keep getting screwed by Nvidia in the mobile realm with how weak Polaris 10 is. The days of 680m vs 7970m, the last time AMD was relevant, seem so distant now.

Well sounds like you guys couldn't wait and already got licenses. You didn't wait long. I wasn't willing to put much money in anyway. I have desoldering the eeprom and reprogramming it as an option.

Eurocom is notorious for poor support. Dota2 will have a pre dx11 codepath. It sounds like just dx11 doesn't work for some reason. You can try reinstalling the dx11 redistributable.

The card sounds ok. If it was bad you wouldn't be able to open the nvidia control panel.

This is weird. On a P150EM the 980m would be running now. Also weird is that Aero isn't running. The HD3000 supports that by itself, so the 980m shouldn't break that. I'm out of ideas other than a full windows reinstall.

So a little update... the integrated graphics can exceed 94 fps perfectly fine, so this does seem to be optimus related.

You tried a 358 driver with a .inf mod? Also you enabled the 980m in the nvidia control panel?

Are you using a Sandy Bridge CPU? The integrated graphics on those only supports DX10, so maybe you ran the render test on the iGPU and the 980m is not running?

Probably. Dell Nvidia cards usually work fine in Clevo systems. I can't guarantee this though as no one has tried it.

It should work in a P151EM. It works in the P150EM. The P151EM is off the same line as the P150EM, but is missing a power phase on the CPU and CPU overclocking support. GPU support is unchanged. I'd try wiping all video drivers then running DDU. Install the intel driver, then the Nvidia driver. Upgrading GPUs on optimus/enduro systems sometimes has quirks, so there's likely some info leftover specific to the 680m that's messing up the 980m.

@Mr. Fox You would run superpi Have you tried more than 1.2V on memory? I've found DDR4 to scale linearly with voltage. Ex 1.35V would get you a 1.35/1.2 = 1.125x speed increase with no memory timings change.

@senso Nice. It sounds like if the integrated graphics is not necessary (dGPU with direct screen access) that the laptop would work fine? I find in interesting that Ivy needs a microcode update to run. Sandy Bridge CPUs did not and worked without any microcode update. Without an update Sandy's temp sensors were erratic and x87 performance was poor, but they did run.

They do have a controller, but it doesn't seem to care with the battery info suddenly changing. I also did not have a fully dead battery. Maybe if I did the controller would have locked up.

36x series drivers don't run correctly on the v2 BIOS. You need to step back to a 358 series driver.

So I finally tried "upgrading" to windows 10... 3d performance is horrific. Anything modern that's fullscreen is capped at 60 fps and microstutters. If I select windowed mode the cap is removed and stuttering is gone, but performance is still around 5% lower than win7. I tried uninstalling the xboxapp, but that did nothing. A 60fps cap sounds like Vsync, but I have vysnc forced off in the Nvidia control panel and my monitor refresh rate isn't even 60, it's 94 (overclocked)... When Googling this issue it seems to only pertain to laptops. It appears that optimus and enduro are just busted on win10. Does anyone have an optimus/enduro laptop that does not have this 60 fps cap? I did do an upgrade instead of a fresh install, but I don't see why that would impose a 60 fps frame limit cap. I'm using a P150EM with a 980m. This performance is terrible and I'm about to just go back to 7 and throw away my win10 upgrade.

@tony84 The 700 and 800 series can be used, but require a special bios mod and other work. The 900 series are easier to get running and are much faster. If using default bios you can only use drivers pre 360 series, and all drivers require a .inf mod. With prema v3 you can use any driver and no .inf mod is required.

This is odd. The GPU is reporting only 1.1 support, so the laptop will refuse to try 2.0. What laptop are you using and what's your driver version? Have you tried a "fresh install" when installing the driver? You also may want to try older drivers. 600 series might not be tested properly anymore on the latest releases.

It sounds DOA to me. The p370em can detect a 7970m from any vendor and vbios version.

All I can see them doing is dropping the power limit.

I expect the higher density chips to work, but I don't know if you can get the higher capacity. I learned that memory actually does contain data on its capabilities, but most BIOS never bother reading it, so if it doesn't ask who made it, I doubt it asks its size. Flashing the 4GB card's vBIOS on to yours should do the trick in enabling the capacity by my understanding, if you can get a hold of it.

There are 3 different GPU heatsinks for P150 series as the series progessed. For the ones you linked, the upper is superior to the lower. The reason for this is on later models Clevo made the core heatpipes thicker. You actually didn't link the best heatsink, which has radiators similar to the one in the 2nd picture, but has the fatter heatpipes like the one in the 1st. The heatsink in the 2nd picture you have is the earliest heatsink. It is found in P150HM and P150EM series laptops. The 1st picture is the first heatsink update. This was found in 700m series cards in P150SM laptops. The unpictured heatsink that I described is the latest heatsink. It was used on 900m series cards.

The poster who lost a PCI-E slot is correct in that its very strange that the 2nd slot still works (PCI_E for x16 is on CPU, not southbridge though). You would expect that if one slot died that all would be dead. They both share the same power circuitry.
