M14x BIOS A07 and A08 released

Recommended Posts

Dell quietly released two new BIOS versions for the M14x, A07 and A08.

Changes for A07 are:

Modify SATA speed limit to SATA2

Link for A07

And for A08 it says:

update new VBIOS for N12-GTX2 graphics card

Link for A08

I'm not sure what the change of the SATA speed limit really means, maybe you can now get full SATA2 speed through the ODD, that would be great in case you use a caddy for a second hard drive.

A08 seems to be simply a VBIOS update for the 555m.

As always recently, Dell is pretty mean when it comes to information about the changes in the new BIOS revisions, these two points mentioned above are definitely important and I recommend to apply the update, but I also guess that there are some additional fixes and enhancements which aren't mentioned.

I'm gonna take a look at both BIOS and see what I can do regarding the volt mod etc.

Edit: Seems like A08 isn't up yet, it say file not found when I try to download it.

Edit 2: There's absolutely no difference between the VBIOS in A08 and the VBIOS in the older versions... seems Dell messed up.

just thrown the A08 at my M14x, cant see any enhancement. subjective fps in bf3 raised at bit (at little oc of 740), but i had it v-modded before. fans are unchanged as far as i can tell

you could shovel ur snow up over here, would love some. we only got damn rain in krautland.

//Edit: one thing i noticed: in the bf3 loading screen the gpu clock doenst go all high, it stays at a decent 201Mhz till loading has finished, before it was all up i think.

//edit2: i feel like the fans more active now in idle/low load

With A08 im not noticing anything improved, Im not up for a full GPU analysis but the only difference i noticed was a notably quicker boot up after installing bios, but thats probably just an anomaly.

Lol, I just took a look at the supposedly new VBIOS, there's absolutely nothing changed... :D

Well, seems like Dell messed up, I guess that could be the reason why A08 isn't available on the support site...

The only thing i can think of that the 'vbios' update might be is a modified fan settings, if the fan it controlled by the gpu instead of CPU.

The fan is controlled by the EC, the VBIOS has no effect on the fan speed. They might have changed the fan settings, I have no idea, can't test it :)

Hmmm... when I think about the semantics of the A07 change log I think they might really have limited the machine to SATA2 speeds, not improved SATA to SATA2.

This would explain the reports about the worse SSD performance. If this really is the case, I think it's actually illegal. If the machine gets sold with SATA3 capability as feature, then they aren't allowed to simply remove it later...

So, seems like Dell Released the proper A08, at least its available now as HTTP Download: Drivers and Downloads | Dell [united States]

let me know when you need some testing something

edit: i guess you already know, but if not: a source tells that dell checked the M14x before the CES in Las Vegas and found some bugs, therefor they released the new VBIOS that should prevent us/itself from destroying the machine due those bugs. thats why we are advised to update quick before any machine goes down.

edit2: maybe to avoid the SATA3 issue, take a A06/A05 Bios and just replace/insert the VBIOS from A08. But that sounds risky tho, since the sata part seems to be changed since A07.

ty schnuffel :)

It's up on the European servers since yesterday, I downloaded and checked it, but the VBIOS is 100% identical with the one in all other BIOS revisions...

I don't think the file on the US server is different, I don't even know whether it's a different sever, but I'll check when I come around to do so, just now I can't do it since I first have to get all my files and tools again to do such things, my SSD just died an hour ago... :(

thanks for the info, good luck on retrieving/recreating your workspace. like you say, the bios files are most propably the same, so dont make any useless work for urself.

i still dunno what dell is trying todo here. we will see.

im sorry your Intel 320 SSD died. The data is more important than anything and I have gone through similar years ago on regular drives. I am truly sorry for your lose these are nor recoverable files most likely. You should pursue justice from Intel... perhaps if you bitch about the data loss and the fact their bull firmware fix did nothing and that people are unsuspecting of these issues blindly thinking that Intel told truth on 8mb error firmware fix... Perhaps you could get them to send you a new 510 series or something with Sata 3.

Should work, if not the flash program will tell you.

Little update: In the meantime Dell seems to have fixed the BIOS on their site, A08 now really contains a new VBIOS... so I recommend to all of you guys who flashed the A08 shortly after release to download it again now and flash it. This way you'll get the latest VBIOS.

EDIT: My bad, never mind this... I accidentally compared the A08 vbios to the A01 vbios instead of the A05... nothing changed between A08 and A05. No idea why Dell is saying this on their website.

      Hey guys, first post, but I thought I’d discuss my heatsink fan retrofit in my old M14x r1. 
       
      Old fan was loud and not very efficient: the air transfer rate was around 2 cfm (I’m assuming cubic feet per minute). Finally had enough and decided to swap out the crappy r1 fan/coughing pinwheel for a r2 fan (rated at 10.4cfm). 
       
      I found an old r2 heat sink on eBay (beware though that the heat sink for the r2 will NOT fit the gpu/cpu configuration for the r1. HOWEVER, the fan of the r2 heat sink it is attached to is a carbon copy fit into the r1 MoBo. A few philips head screws and a seal of good electric tape and BAM, you’ve got a significantly cooler and MUCH quieter intake fan in your old R1. 
       
      My CPU temps from before were around 87-88 max load in FSX, 65 for the GPU; bear in mind this is after a repaste. Now with the new fan, I’m not going over 77 degrees on the CPU, and the gpu stays around 58, all while being MUCH quiter. I’ll post pics of the walkthrough if anyone is interested.
       
       Just thought I’d share with all you fellow loonies trying to squeeze every last frame and degree out of our “portable toaster ovens with a screen and keyboard”.

      Hi everyone, I was thinking of upgrading my ram from 8GB to 16GB 1600MHZ either Kingston/Crucial as my current ram usage is at always at 4GB now. Will upgrading make a lot of difference in the performance of the PC and will it improve the game play for GTA V as I am currently having massive lag with this game? 
       
      Thank you in advance.

      Hi everyone,
      I have gone through a lot of pages of this forum (related to eGPU and overclocking) and they really are very useful but not able to find anything good for my laptop.
      My laptop is Alienware M14Xr1 with following configurations :
      Intel core i7 2860QM
      Nvidia GT555m (3GB)
      8GB primary memory 1600Mhz
      750GB secondary memory 7200RPM (698.4 GB usable)
      900p screen

      I want to use a eGPU setup in my system.
      Could anyone please tell me whether it is possible or not to use -
      In my system there are following ports available - 2xUSB3.0, 1xUSB2.0, 1xHDMI1.4, 1xMiniDisplayPort, 1xVGA, 1xEthernet1000mbps, (I think none of these will be helpful in eGPU setup )
      But i have heard that if you remove your wireless card then you can plug in your eGPU there. Is it true,
      Please anyone share your experience with me related to this setup.

      Hi all,
      I am new here, so I am sorry if I have posted this in the wrong section. Also, I realise this question has been asked before, but all of the other threads are really old.
      So, my issue. I flashed the unlocked A08 bios with sata fix and everything worked brilliantly. Then, in my infinite wisdom I turned on UEFI mode in BIOS to see what would happen. What happened is it rebooted with 8 beeps (no screen) everytime I turned on. I looked at the other forums and did the whole usb recovery thing, however, I believed it was taking to long so I turned the computer off after the computer rebooted and beeped 7 times (cpu error). I tried taking out the CMOS to no avail. Now when I try the recovery USB the usb never seems to be loaded (light never comes on). Any ideas?
      Thanks for all the help, and sorry for any mistakes I have no doubt made.

      So Alienware should be gearing up to introduce us to their new redesigned lineup this June. A Chinese website has some leaked images, video and specs of these new models, here they are:
      Changes

      No express card and possibly no eSata.
      Keyboard has been changed and should be similar to the island style one found in Clevo notebooks and others. This should also affect how AlienFx looks and functions compared to previous models.
      New lid design with light strips.
      New base is more blockier in design, old speaker grills are gone and now the front is flat with some speaker lines.
      Touchpad lights up completely.
      Cooling? Remains to be seen, will update as we get more info.
      Option of IPS FHD display in all 3 models.
      Aluminum build for all 3 models though some parts will undoubtedly be plastic - we'll see and update.
