UPDATE: ALL DOWNLOADS LISTED IN THIS POST FOUND HERE. Nvidia 'Kepler' GPUs - modified VBIOS files >>> NOTE: More versions (including voltage mods) exclusive for T|I users can be found in the second post. <<< The 'Kepler' GPUs from Nvidia perform really well, even at increased clocks speeds they stay quite cool - a perfect behavior when it comes to overclocking and improving the performance. Unfortunately the mobile GPUs suffer from an artificial +135MHz core overclocking limit, so you can't go higher by using tools like Nvidia Inspector and similar. The modified VBIOS files listed here have this limit unlocked, some have increased stock clocks or tweaked voltages. Just refer to the description. All files have been modified by myself, if you like them feel free to buy me a drink, donation link can be found below GTX 660m: 660m_OC_edition__VBIOS_[DELL].zip- comes with unlocked software overclocking limits 660m_GHz-Edition_overvolted_VBIOS_[DELL].zip - default 3d clock 1000MHz, base boost 1200MHz,, memory (3d) 1350MHz, increased 3d voltage undervolted editions possible, depends on interest, tba Some screenshots: GTX 680m: Clevo_680m_-_80.04.33.00.10_'OCedition'_revised_01.zip Dell_680m_-_80.04.33.00.32_'OCedition'_revised_00.zip Increased software overclocking limits & optimized for no throttling. Read the included 'Read me' file before flashing. Instructions: I recommend flashing under DOS using nvflash . Donation link in case you want to buy me a beer Thanks and cheers! More to come.

********** * This is only for systems with Intel chipsets. * * It still won't work for all of them, but for some it does. * This article is meant as an explanation for interested / advanced users. Since some of the more recent bios mods require the tool described below in order to allow flashing, I decided to share some information about it. Also I really don't like how users get locked out of their own hardware, this is a way to circumvent a couple of the more recent restrictions of certain systems. I hope this will be useful to some of you. If you know other ways to get around the current firmware updating restrictions (per software), please let me know. The problem: With the appearance of Windows 8 and Microsoft's requirement for OEMs to support 'secure boot' in order to get the Win8 certificate for their machines, a lot of the most recent systems (notebooks and desktops) use now firmware which is digitally signed. Since secure boot looses its purpose if firmware updates aren't verified and protected as well, the latest UEFI implementations come with a secure firmware upgrading procedure which makes sure that only properly signed and unmodified images can be flashed. This updating protections is active even if you don't enable secure boot. These two pictures explain the idea behind secure firmware updating very clearly: On the second picture you can see that the system verifies the firmware image even before it loads the drivers required for the flash. For bios modders or people who want to use modified firmware, the consequences of this are severe. It simply isn't possible anymore to flash digitally signed bios which have been modified, there's no way around the signature, at least not with the usual tools. The solution (at least for some systems): The only way to get around those new restrictions is to directly program the firmware flash memory and therefore leave out the verifying of the image. In Intel systems the flash chip is directly wired to the PCH, and it can be accessed by an Intel utility called Flash Programming Tool. It's a very powerful application which supports the most common flash memory chips. The requirement for it to work on a system are the following: - BIOS region of the flash memory must have write permissions - The OEM or BIOS vendor omitted to set an additional flash lock. - You can't flash an encapsulated firmware image, only the pure bios region. You will have access to the BIOS region for obvious reasons, but the second point can only be figured out by trying to flash a BIOS. If the tool comes up with an 'Error 28', download the attached 'prr' utility, as well as the DOS version of the flash tool. Put both on an USB drive which can boot DOS, boot from it and execute the prr.exe, if it manages to remove the protection on your system it will tell you 'ready to flash', in this case go ahead and directly flash with fpt, without rebooting before doing so. If prr can't remove the protection you're most likely out of luck, even though might be ways for certain systems, but the chances are pretty small. In order to flash a BIOS you will need to remove the capsule from the firmware image provided by your system manufacturer. You only want to update the bios. Then flash it by using this command: fptw64 -f FILE -bios (FILE stands for the image you want to flash) ***WARNING*** This tool is only for very advanced users. If you mess up it will override your BIOS without a warning or waiting for you to confirm. This means you can easily brick your system beyond any chance of recovery. You most likely don't need this tool. My BIOS mods which require this application for flashing will always come with a .bat file which will do the flashing for you. Again, for 99.9% of the users there's no need to mess with this. This version of the tool works only for 7 series chipsets. *InBeforeOmgMyYystemWontBootAnymore* The tool provided here by svl7 (prr2.exe and former prr.exe) may not be hosted anywhere outside of Tech|Inferno without the previous approval of the author.

Just on my second Orion backpack from dell and its developed another fault - the solider straps are tearing at the seams. The first one lost its protective foaming in the laptop compartment. Alienware Orion M17x Backpack Just wandering if there is an alternative that can fit the 17x comfortably. Thinking of the swissgear but it seems to be up to 17" laptop sizes and dont want to risk it. Thanks! PS the Checkpoint friendly is a load of rubbish as you *always* have to take it out anyhow.

Yeah, I did. I figured out what's wrong. I also copied the files from the folder when I didn't see any files in the USB. So that might have screwed stuff up. All is well now! Thanks for the fast reply <3

oh no! i bought a 675m from upgrade monkey some weeks ago. i sent it back since it didn't work with my m15x. it didn't access 3D states at all.. even when trying modifed vbios from svl7.. i'm afraid you won't have luck with that card. i bought a 7970m from mxm-upgrade.com and that's pretty rocking my m15x!

Got a new motherboard, tried A11 Unlocked V2 and worked perfectly .Great work guys!

Furmark crashing indicates you probably have power starvation. Try a higher specced PSU. A GTX560Ti448 is pretty much like a GTX570 which can require up to 298W at full load. You'd need a PSU with a single rail capable of supplying at least 12V/25A to reliably drive it. Your GX640 has a Series-5 chipset (pci-e 1.x), a H5850M dGPU and no iGPU. So you would see straight x1 1.0 stuttering/poor performance from your GTX560TI. Only way of improving it would be doing a x2 1.0 implementation requiring an accessible adjacent mPCIe port. You would still find the HD5850M dGPU performs better than the eGPU even after doing that. A more cost effective solution would be to offload the notebook and replace it with an inexpensive Series-6/7 one (pci-e 2.0) with an iGPU, eg: HP Probook 4530s, and purchased a pci-e 2.0 capable PE4L-ECxxx/PMxxx 2.1. Then you'd see x1.2Opt performance which is considerably better. How much better? See the x1 1.0 versus x1.2Opt comparison at http://forum.techinferno.com/diy-e-gpu-projects/2747-12-5-dell-e6230-gtx660%40x1-2opt-hd7870%40x1-2-pe4l-ec060a-2-1b.html#post37197

Hi guys! In connection with the fact that I badly know the English language and for writing this text use the translator may not everyone will understand what I wrote. Please forgive me,but I need Your help And so, two days ago was my adapter PE4H ver2.4+EC2C,after connecting in him GTX560Ti all earned with the use of an external monitor 1080p and my laptop. The question here is when playing Battlefield 3 and World of tanks Fps significantly sinks,as well as present a stuttering. How can I solve this problem? Thank you in advance!
