Just copy all files from folder "x64" directly to the root of your bootable USB flash drive, and try again.

This is for you. GK106.zip

Try use Nvflash to save the VBIOS. Also try before save vbios, disable NVIDIA card in Windows Device Manager. Also you can try uninstall NVIDIA drivers, before save vbios.

Here you go. Core clock unlocked. Dell-K5000M-ORG.zip

Just read carefully first page of this link: http://forum.techinferno.com/nvidia-video-cards/2166-%5Bguide%5D-nvidia-vbios-flashing.html - - - Updated - - - Post here your stock vbios.<!-- google_ad_section_end --> - - - Updated - - - Update version of your GPU-Z from 0.8.2 to 0.8.4

Post here your vbios.

Check your mail box.

You can try. But it is not so simple. For modify vbios you need have some knowledge and expirience in this area.

Just flash vbios Nvidia GTX 780m - 'OC edition' - rev02.zip from the first page of this thread, and you will forget what is throttling. Of course you need flash both card. Before start flash, read carefully instruction on the first page of this thread: http://forum.techinferno.com/nvidia-video-cards/2166-%5Bguide%5D-nvidia-vbios-flashing.html

Ok. Just enjoy!

Done. Check your PM box.

FPT(for DOS) or fptw64. You should use correct version for your platform.

Of course tested. Very stable. All clocks is stock(default). Tweaked for better performance at higher clocks - stock default clocks - adjustable clocks - higher software overclocking limits.

Send me the file backup of your bios.

What the help you ask?

Send me the file backup of bios from your laptop.

Just flash ge70_e1756ims.514_win8_oc.zip. from the first page of this thread. It is very stable bios. Bios from the msi ge70 2od dont compatible with your laptop. This laptop have different platform.

What's the bios version in yours laptop now?

Check your PM box.

Here you go. ASUS970M.zip

Check your PM box.

In this case, does not big matters what the power of the heatsink(75 or 100W), but the internal shape, arrangement and shape of the alluminium little projections there on. Heatsink for 560M differs from heatsink 880M with configurations alluminium little projections. Now some VRM on the 880M have overheating in his laptop.

May be your heatsink for your old card, and doesn't completely compatible with your new 880M.

And of course you can flash vbios for MSI GTX 680M with 2GB.

Just type in Google "Silicon Lottery", and you can see very much info about your question. For example like this: What is the silicon lottery? - CPUs, Motherboards, and Memory - Linus Tech Tips CPUs of a particular series or model are not exactly identical. Some overclock better than others. The lottery means you have lucked out and gotten a good one for OC. There is no way to predict until you reach the upper bounds of overclocking. Quality of memory controllers of the identical CPUs have differs. One can be stable with 2400, but other one do not stable with 2133. It is normal. When chip manufacturers like Intel, TSMC, UMC, GF, etc. make wafers, there are slight variations in material quality across the wafer surface, there are local variations in how the lithography, metal vapor deposition, photoresist chemical deposition, etc. are done and this can yield a significant contrast between how good the best chip of a given batch will perform vs how bad the worst chip of the same batch will perform. You have absolutely no way to know beforehand how much farther beyond that your specific chip can go under any given circumstances beyond stock conditions. That's the chip lottery. Some i5/i7 may max out at 4.2GHz while others may hit 5GHz. With CPUs memory controllers happens exactly the same things.
