Prema,

I have your BIOS in my P150SM. What would I need to install / flash to get a 980m to work?

Jason

svl7,

I have your modded vBIOS, i've tried disabling driver enforcement, i've tried the -bcdedit trick, i've tried safemode, and I cannot get 340.52 to install. It says something about the card not being recognized. I presume this is due to the modded vBIOS. What should I do? (And if the answer is to flash the vBIOS to stock just to install a new driver, and do that every single time... it's gonna be really sucky)

Prema, what is the BCLK function that you say "do not go past ME 9.0"? on.

Is that relevant to high-speed RAM, or is that more for those who want to OC the CPU?

Jason

NVIDIA GeForce GTX 780M video card benchmark result - Intel Core i7-4800MQ,Notebook P15SM

(not bad for a GPU / CPU that haven't been OC'd)

I see constant 850MHz with SVL7's BIOS. Max temps are about 73 to 76C. I may do a repaste in the near future.

Nope, there was no option to change into legacy BIOS mode. There was a setting for boot type, and it has only one option: UEFI.

Within the UEFI mode, highlight it, hit "enter". it should pop up with a menu that says "enabled / disabled". Clock on "disabled". Reboot into the Legacy BIOS, and then flash. The only thing I can think of is that you may have accidentally turned Secure Booting on or something.

EM Systems don't gain extra options like all the others. All changes are under the hood.

(For Dennis)

Wait, so do we have to flash in a different way if we have UEFI?

If you have the UEFI mode enabled, you may want to take the computer out of UEFI mode JUST to flash the vBIOS. Once the vBIOS is flashed, you can put the UEFI mode back on, and go back to your computing.

That's how I did mine. (See sig for laptop)

I actually don't think I have an option to disable it... either that or I'm not looking hard enough. I'll try again.

At boot, hit F2, go into BIOS, then find how to disable UEFI.

Some initial observations with SVL7's modded vBIOS.

I've had the BIOS for the past 2 days, and although I'm not an overclocker (ie: I'm not going to be an aspiring JohnKSSS or Mr. Fox anytime soon), it's a very well put-together "vBIOS" even for regular use. The features that make me love my NP8265-S (adjustable GPU clockspeeds for when I want GPU for 4K video, Optimus for when I'm in class and I don't need a dGPU for doing office work, etc., are all there), and I can get 850MHz at 1v (according to GPU-Z). Even the controls for things such as brightness, which didn't work in my previous laptop (an NP8130) when I decided to change the GPU from a 560m to a 675m (and did the corresponding PSU swap), still work as advertised.

As far as heat goes, I'm still peaking in the low 70s when gaming (Shift 2: Unleashed, Dirt 3, Project CARS) with all settings high / ultra. But I'm not breaking the 1.0000v threshold according to GPU-Z even after hours-long gaming sessions. Compared to the stock BIOS which would hit 1.0625v (and sometimes higher) to attain the same 850MHz peak speed, every little bit less energy, even if it's just 62mv, helps reduce heat and extend life. (NB: I'm not complaining, this laptop also goes to school with me.) Now that doesn't mean that I can go "I have an ultrabook!!!!!", but it does mean that there's less stress.

Now, to get some stuff out of the way that I've noticed. I AM using a UEFI mode on my Sager (Prema's Modded BIOS, also highly recommend for its adaptability / usability), but I am NOT using the secure boot option in the BIOS. I have a hunch that with Secure Boot on - either via someone accidentally going "ooh what does this button do?!", or just by default when one buys a rig with Windows pre-installed (I have a feeling that Windows 8 / 8.1 does that when factory installed, and as such makes things more difficult, but that's just my conspiracy view), that it compromises the ability for the end-user to make the necessary adjustments needed / desired on his / her rig. Again, this goes back to the premise that BIOS flashing / modding is NOT something to be taken lightly - be it at the GPU or Mainboard levels - and I gather that most companies - even gaming companies like MSi, Sager / Clevo, and Alienware - do not want the headaches of inexperienced people going and blindly changing everything around... for them, it's "idiot-proofing" for the sake of reducing liability. For someone like me, it causes headaches... but as with most places, we're the overlooked minority.

This brings me to the 880m issue. From what I can see, it's not the fault of SVL7, JohnKSSS, Mr. Fox, and anyone else who either develops modded vBIOSes, or overclocks laptop cards to beyond desktop levels (ie: Mr. Fox's insanely awesome dual 780m Alienware). It lies, as Mr. Fox has correctly asserted, DIRECTLY in the face of nVidia. However, I'm not going to look at it just from the premise of "it has a 100MHz-plus headstart, so it should at least match - if not stomp - the 780m's performance"; rather I'm going to approach it from a "bang for the buck" perspective as well. If I have a 780m, which has standard speeds of 823MHz / 849MHz, and I hit 849MHz out of the box, no mods, no effort, then I am getting, per nVidia's site, my rendered service. For example: if by some "silicon lottery" luck, I am able to OC my 780m to say... 954MHz (the 880m's "non-boost speed"), then I consider that "a great perk", because I'm getting approximately 105MHz of Free, Usable, Performance. Conversely, if I have a 880m (954 / 993), yes I have to squeeze out all that extra power without raising the TDP, but because I've been conditioned to get "GREAT" bang for the buck from the 780m, I may think to myself "I can get something like 1100Mhz out of the 880m's with the same amount of effort, assuming other factors such as ASIC quality, silicon quality, etc., are equal". That's very rarely the case. I'd rather get "free performance that's unexpected" than to have to struggle to even get "advertised speed".

Personally, I would have rather seen the 880m been a high-performance Maxwell GPU and had nVidia wait a few months, than to see what they call "passable"... if the R9 M295X is what it claims to be... nVidia's desire to have "first-mover advantage" may have just given AMD a very big "second-mover advantage"... at least until the AMD card starts blowing up PSUs....

Jason

which computer do you have?

Is it possible to add 'hdd password' to BIOS so I can take advantage of the encryption in my SSD (Samsung 840 pro)?

Yes. It is in the BIOS settings. Conversely, I believe there is an encryption option as well in Samsung Magician 4.3.

Ah, so 1866... i can just drop-into a Prema'd laptop.

2133, and I set to 1.33 x 16 in the BIOS

Ah, OK. I'm asking b/c the RAM I'm looking at, is HyperX Impact Black Series 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 2133 Laptop MemoryModel HX321LS11IBK2/16 - Newegg.com (2 sets of this). Allegedly, it's Plug n Play though.

Jason

Right, so to flash... disable UEFI.

Once Prema-BIOS is flashed, re-enable UEFI.

Then enjoy.

Thanks Prema!

So now that the BIOS is flashed to PremaMOD mode, if I want to put in 2133 RAM, I just plug it in, and then what? (I'm thinking 32GB DDR3-2133 for a faster RAM drive)

Jason

The only reason to disable UEFI is that the system (everything after EM Series) can't boot from the non-UEFI USB stick as long as UEFI is enabled.

Right, so to flash... disable UEFI.

Once Prema-BIOS is flashed, re-enable UEFI.

Then enjoy.

NO

PREMA says to disable UEFI and flash. follow the instructions on his site

Sent from my Note 3 (SM-N9005) using Civz ROM [v3.5] with Kernel SkyHigh TW Kernel [v2.5]

Got it. That makes everything clear.

AFTER the flash, I go back into UEFI, right?

so it seems 780m's are fine, 880m's are borked?

$10 sent to SVL7 for his awesome BIOS!

Receipt No: 4135-5042-5065-4598

So I can do the BIOS flash even in UEFI mode, to the PREMA bios?

My Mod allows 2133Mhz, 2400Mhz or even 2667Mhz, On first boot they will run @ 1866Mhz, then you can select the desired speed in BIOS and it'll run on that from then onward OS independent on that speed (if the RAM can take it).

If my Sager's BIOS is in UEFI mode, is it as simple as "get out of UEFI mode, flash PREMABIOS, go back into UEFI mode" ?

Jason

All this 780m / 880m wondering is interesting. Is there some sort of e-switch that the 880m's have that is triggered by a BIOS flash? Because even with a 780m, and my Sager's BIOS in UEFI mode, everything works fine.

Well, before I updated to the latest beta driver, I had no problems over clocking my 880m. Now, since updating, I have nothing but problems over clocking. Here's just one of my problems. I restart my AW, instantly, I'm unable to over clock in any program. I have to start up Nvidia Control Panel to kick my vbios back in to action again. I'm in the middle of formatting to Windows 7, as I'm starting to think Windows 8.1 might be the issue. I'll post back with my findings. If it doesn't resolve my problem, that's it, I give up. I'm glad your 780m is functioning correctly matey.

Could it be the OC part causing the problem? Or do 780m's, even with 340.43 and the unlocked BIOS, have no problems OCing in 8.1?

Jason

Hey Prema,

Do you have a BIOS that can be used to allow the P150SM to use DDR3-2133 RAM?

Jason

Excuse me, what?

I've been told that the 780m runs nicely regardless of whether you're running stock or modified. Shame that the same can't be said about the 880m. I'm in the process of downgrading to Windows 7, in hope that this fixed my problems. At this point, I'm thinking it could be Windows 8.1 at fault. It's not exactly renowned for being a very good OS.

Insofar as: I meant "what does it do to kill SVL's vbios?". I wasn't being sarcastic / snarky / cheeky. I apologize if it was taken as such.

As for the 2nd point, the 780m works fine for what I need it for. If I were to upgrade ANYTHING, i'd want to put 2 msata SSD's in RAID 0.

Avoid the latest beta driver. It may kill Slv and John's vbios. It's crippled me left and right for the time being, along with a few other members here and over at NBR.

It works very nicely in my 780m. I ran 3Dmark in a loop and didn't observe temps over 77 Deg C. It's a Sager NP8265-S, but as I said earlier, I'm not going to OC this laptop.
