my M15x seems dead for no obvious reasons, simply one day worked, the other day not. No liquid inside. Battery is very old so I use notebook without it.
The symptoms are that it does almost nothing. When I press power button, nothing happens. Sometimes, when I hold the power button, it blinks twice (the power button only).
After some checks I suspected the motherboard so I bought a new one from ebay, reinstalled everything but it behaves the same. It could be faulty too but the probability to have two motherboards with the same issue is very little.
I tried to run it without RAMs, with different AC adapter, no change. Now I'm guessing that the CPU could be dead. But don't want to waste another money just like that so I hope someone from you, experts, could face the same earlier and I can learn from it.
Do you know how M15x behaves when CPU is completely removed? And what if GPU is removed? This could help me to isolate the origin of problem.
Hello I have a gtx 660m. I Put it in my m15x with a 1.5mm coper shim. It fit good, also added paste. I have windows 10 and have tried every driver none are working. the eurocam driver I got off from their site for the 660m upgrade starts downloading and 2 minutes into the install, it fails, and an error pops up, "install failed" and that's it. please help :\ NOTE: The 660m is showing up as unknown in the device manager but I can still manage to get the hardware ids.. Also I believe my bois is a08 I downloaded a09 from dell and it just gave me a folder with some files in it no download setup THANKS!!
I've managed to brick my graphics card trying to install an undervolted vbios. I'm running an M15x and so can't slot in an extra card to run the screen in order to flash another vbios.
I'd be happy to pay to cover anyone's time.
Hi guys, im new to the forums. Looking for a little help.
Been on so many forums and tried so many things.
So basically my 260m in my m15x kicked the bucket. So i was using the onboard gpu but i couldnt game. So i decided i was gonna take one of my 6970s out of my m18x and fire it in the m15x.
I read that it was possible, so i got the bios file to make it work in the m15x, got the card prepped and installed, then proceded to flash the new bios for it. Flashed it, machine turned off to restart i presume. And nothing. No power at all. Tried the power button and nothing.
No lights at all coming on, not even charging ones.
Removed the gpu = nothing
removed the cmos and discarge = nothing
blind flash = wont come on to do it
so kinda crapping myself right now.
So i had a look online for a new motherboard and holly god are they dear. So i thought i may be able to salvage it with the correct bios so i have ordered the bios chip to replace the one thats on it, local place gonna do it for £35 quid. Hoping that solves the problem.
Question is. Is there anything else i can try to make it work. And if the new bios chip fixes the boot issue how can i get my 6970 working in this machine without having to go buy a new 260m. Quite like the idea of having a powerful card in my college laptop. I used the bios that had the volt mod, so it ran cooler, think there was 3 to pick from.
Anyhow, thanks for anyone willing to help me bring this beast back from hell
Guide – M15x with Nvidia GTX 470m
IMPORTANT: The Nvidia 470m is not officially supported by Dell. Upgrading to this card may void your warranty.
Some background to this mod: The first guy who tried to put a Nvidia 470m in an Alienware M15x was @iloveb00bs in December 2010, shortly after the card got released.Unfortunately it didn’t work as desired, the card worked, but only at 2d clocks. All attempts to bring it to 3d clocks failed, and the card wasn’t supported by Nibitor support at this time.Also @widezu69 didn’t get it to work a couple of weeks ago, so I didn’t think it would be possible. But in the process of trying to upgrade the Asus G73JW of a colleague I got my hands on a Nvidia GTX 470m and since we didn’t get it to work in the G73, I thought let’s try it again in the M15x.
I had to mod the vbios to get it running at 3d clocks. I’m not that experienced with Nvidia cards, so that’s probably why it took me a couple of attempts to get it working.
First I changed the 2d clocks and voltage (P3 in Nibitor) to 3d values. The result was that the card idled at 3d clocks, but as soon as I opened a 3d application it went downclocked itself to about 73MHz core and got to 2d voltage again… pretty annoying.
After some more tests I realized that I had to change the lower 3d clocks and voltage (P7 in Nibitor). This did the trick. Apparently the card only checks P7 and P3 in the VBIOS, the actual 3d clock entries (P15) seem to have no effect at all.
The fan control works perfectly. Haven’t tested DP/HDMI audio yet, but I’ll do this sometime soon.
Things to do before exchanging the card:
Download the drivers. I used the latest Nvidia beta driver (v275.27) and the modded .inf files from laptopvideo2go. As the card comes from Clevo I guess the Clevo (and resellers) driver will work as well. But I usually prefer the latest driver for performance and stability. Also get GPU-Z for monitoring your video card and verifying it. Make sure you have thermal paste, maybe some new thermal pads as well as something to
clean the heatsink (e.g. isoproply alcohol) and some cloths around. I also highly recommend using a grounded ESD-mat and a wristband. Know what you’re doing. You need to partially disassemble your machine to get to the GPU. Prepare yourself thoroughly, check out my little GPU exchangement guide and if you need more information also the M15x service manual, as well as the official teardown video. It can be helpful to write down all the steps in advance when you’re doing this for the first time.In case there’s still something unclear about the disassembling procedure after checking out all the stuff I just mentioned, just ask. Exchanging the GPU is really pretty easy. Very important: Make all the necessary preparations to flash the modified vbios to the card in order to get it working at 3d clocks:You’ll need a DOS bootable USB drive with NVflash on it. If you have already such an USB drive you can skip the next step and simply copy the mod470m.rom file from the attached archive to your stick. If you first need to create such an USB drive follow these instructions:
Creating a bootable DOS USB drive (by @Brian ) Step 1: Download all the following files as they will be needed throughout this guide.1. Download the HP USB Key Utility: HP USB Disk Storage Format Tool – v2.1.8 Download – EXTREME Overclocking2. Download the Windows 98 system files: Windows 98 System Files Download – EXTREME Overclocking Step 2: Creating a Bootable USB Drive to Flash to GPU1. Install the HP USB Key Utility2. Launch the HP USB Key Utility and do the following:
- Insert your USB thumb drive.
- Select File system as “FAT32″
- Select Format Option as “Create a DOS bootable Disk…”
- Checkmark the box that says, “Quick Format”
- Locate the directory you extracted the Win98 files.
- Format the USB key using the the Win98 files.
The upgrading procedure:
Then (after reassembling your system), boot, install the drivers and reboot. Make sure the fans are running (otherwise you probably forgot to plug in the fan). Open GPU-Z and verify your card and the clocks.
Default 3D clocks are 535/750/1070 MHz (core/memory/shader), you can see them in the “Graphics card” tab of GPU-Z.
Make sure PowerPlay is enabled in the Catalyst Control Center. Also make sure Stealth Mode is deactivated.
Check your temperatures. Idle temps should be 40-50°C, depending on your ambient temp of course. While gaming or doing something similar GPU-intense the system will run significantly hotter, 60-70°C, maybe a bit higher.
-Plug in your properly prepared USB drive
-Make sure your system is plugged in (AC adapter and to be safe battery as well)
-When you see the Alienhead press [F12] to get to the boot menu, choose “Boot from USB”
A command prompt will appear.
First of all, make a backup of your original 470m vbios! Use the following command:
Code: nvflash -b orig470m.rom
Before flashing, test whether the file isn’t corrupted (errors while copying it to the stick or similar):
Code: nvflash -v mod470m.rom
The image size must be 64000 bytes and the CRC32 3C8FA599
Now flash the modded vbios:
Code: nvflash -5 -6 mod470m.rom
Press enter. A couple of warnings will appear, follow the instructions on the screen to confirm the flash procedure.
Remember, some Keyboard layouts have the [Z] key at the place where the US layout has the [Y] key. So in case you have such a keyboard you’ll need to press [z] instead of [y], otherwise the flashing procedure will get cancelled.
Then press [Ctrl][Alt]+[Del] to reboot your system, unplug the USB stick. You can use GPU-Z to verify the flash of the vbios. It should look like this afterwards:
Here some first benchmarks, both at stock clocks, PhysX off and the rest in the Nvidia control panel on standard settings, CPU at 3.2GHz.
I haven’t seen other 470m benchmarks of other systems, but 9k stock vantage seems reasonable.
The card is probably pretty overclockable, but I haven’t tested this yet. I have yet to find overclocking tool with which I can set the core clock manually, so far I only managed to change the memory and shader clock with Nvidia Inspector. Otherwise I’ll have to modify the vbios in order to overclock it (which isn’t the best solution as I can’t really push the card with this method) However, it seems the card can be overvolted, haven’t tested it yet but Nibitor allows me to change the voltage to 0.99V (instead of 0.94V).
The only issue so far is that the card runs either at 3d clocks or at 2d clocks. Nothing between this.
