Mobile Pascal TDP Tweaker Update and Feedback Thread

Wow.

So there have been absolutely zero records of flashing modified vBIOSes besides power limits?

WTF, nVidia.

 

Its annoying since we cant affect boost other than raising TDP and undervolting. It's absolutely annoying.

 

Wow it's been a long time but this forums never ceases to impress me.
I have just came to this thread by chance, and if it is not too much hassle to anyone and since I do have a pair of Desktop's Titans Xp I would like to know if this tool can be used with them and on a second place (I do have them watercooled) will it help to get them clock higher or more stable?
Any downsides of using this tool with them if possible?

Kind regards folks and a big hugh to brothers Mr.Fox & Prema

 

Hi, i have flashed my Clevo p775dm3g gtx1070 recomended settings vbios with usb programmer , but card crashes in games or benchmark after few seconds, black sreen fans 100% on and light blinking. Any suggestions what could i have done wrong?

 

pushed it to far, failed OC

 

Yep what did you alter it from and to?

If you're trying to push too much through the vrms they can trip ocp. Wouldn't think they'd be overheating after only a few seconds unless your thermal pad contact is dodgy

 

What settings did you put in the pascal bios editor?
Did you press the preset button?
did you manually change or edit any values? If so, which?
What were your overclock settings in MSI Afterburner for core and memory offsets?

 

Hi. I opened saved vbios file with pascal tweaker and only did press ''preset'' then save. Then write that file with programmer again.
no overclock i just set power limit to max 112%. Card crashes even with no overcloc, but runs smooth for 3 or 5 seconds in any game or benchmark.

 

I took out heatsink and noticed that heatsink didn't touch GPU DIE fully, can it be the reason why card disables itself on high usage?

 

Oh god, yes! That's why!

 

The thermal pads with the biggest indentations are the ones that are inhibiting core contact.

Also I always put them on the chip (rather than first stick them on the heatsink) - it looks like you have partial coverage in a couple places and have other things unintentionally stuck under the pads (e.g. inductor "2R2" between memory chip and SLI port)

 

Thanks for this.
I added more paste and it works now. The other question is what core clock and memory i can set highest with ''Preset'' setting set 170000 151000mW on Pascal vbios tweaker? It's GTX1070.

 

You're not gonna know how high you can set the core and memory until you try it. Each chip is different, some can overclock further than others.

 

The higher the TDP, the less you can clock the core.
At 115W TDP, you're going to be throttling so much even +250 mhz on the core may work, since you're going to be sitting around with the clocks getting whack a moled between 1603 to 1750 mhz unless you're in an old game with <80% GPU usage.

On a cancer restricted vbios where the maximum vcore was capped at 0.881v, +225 mhz was fully stable. (at a cap of 0.881v, you should be under 150W at all times unless you use Supersampling AA/DSR/ Render scale >100% (e.g. Overwatch).
At 230W TDP, you may not be able to pass +135 mhz on the core.

RAM depends on the age of the card. Newer 1070's with 9 gbps chips (which newer 1060's got first, then both desktop and MXM 1070's got the upgrades) can do +1000 mhz on the RAM. The older 8gbps chips can usually do +500 to +700. Note that +700 may get unstable if the card gets past 60C; if you start seeing random flashes, try +675 instead.

As far as I know, all of the TM1 systems have the newer cards with 9 gbps chips, but the editor won't work on them because it's too old and can't write the correct locations.

 

You might benefit with replacing the pads and playing with thickness to improve contact.

 

Oh yeah, I agree, definitely! (I had overlooked that he said he just added more paste to 'fix' the issue)

 

Hi
Anyone had success in modyfying GT1030 Desktop Card?

Mine vbios from 2GB DDR5 Zotac card, low profile version
https://mega.nz/#!0ZlFhDzD!85Lk9FqL-ry4E3WDz05mopAla0Guszbwi7DJaBAmstM

 

This editor is more than a year old now. Most likely any cards that were not originally tested would not work, and none of the 6 core equipped vbioses would work UNLESS you were using an older 4 core system (e.g. Z170) and used the hardware mod to allow 6 core processors to work--those vbioses (1070 and 1080) can be modded since they're the same as the tested ones. Systems which SHIP with Z270 chipsets thanks to Ngreedia have newer vbioses (or black screen if you try force flashing an older vbios on) and those are not supported.

If you know how to crack the checksums, you can do your own vbios mod even on a Titan V, but only one user on this entire forum knows how to do that.
Maybe two.

 

Whait a moment.

YOu say that what? Not really fully understand you.

My test spec:
i5-44xx
msi h81m-p33
8GB laptop DDR3 RAM
rest not imporant

What you tell about 6core CPU? What CPU have to do with modded vbioses? Or maybe chipset?

Is other checksum that the editor fix other that anyone can fix manually? You can hex edit vbios and use that tool to fast fix checksum to original numbers or do it manually. You saying that is another checksums?

Yes i had black screen, at this moment get even vnc connection (not always) but of cours 640x480 resolution. But is black screen.

Even another (unmodified) GT1030 vbioses works (already flashed few) normally. OF course not 1050 for example.

 

Yes, sounds like it's unsupported.

 

Hello to the forum; this is my first post but I've lurked here for months (well, years on and off).

I've particularly taken interest to this vBIOS section of the forum as well as the MSI GS63VR sub-forum (even though I don't own the laptop but instead an Aero 15X v8). There's just an abundance of knowledge here so I'm hoping to get some advice on a project I've been working on for the past several weeks.

I'm currently researching PCI passthrough of the Nvidia GTX 1070 Max-Q found in the Aero 15X v8 (Coffee Lake 6C) and reading some of the posts here has led me to some conclusions that I can't fully understand.

If anyone can help me with this I'd appreciate it, but I have the following questions:

1) Why would a 6-core CPU affect the vBIOS? Is this simply because Coffee Lake mobile CPUs are being shipped with newer chipsets and it has nothing to do with the CPU, or is there a relationship between the CPU and GPU vBIOS that isn't obvious?

2) I've noticed many people state their GPUs (MXM, BGA, muxed, muxless, etc) come with an EFI BIOS pre-loaded. Thanks to the good folks on this forum, I've wired up a test clip harness to dump my EEPROM and I've seen no evidence of any EFI section. Is there anywhere I could get an EFI capable ROM for the 1070 Max-Q assuming Gigabyte and Nvidia wouldn't give me one?

3) Could this card be cross-flashed? I see in the quoted message above that this might result in a black screen? Is this unsafe on the newer cards?

4) I've read several people state that the newer Nvidia vBIOSes are "encrypted." Is this true? And if it is, are there unencrypted versions on the internet that could be cross-flashed to replaced encrypted versions on one's own board?

...

My goal here, to be clear, is to try to get an EFI compatible 1070 ROM working on this board, particularly one that might be more compatible with OVMF (which does not support CSM). This could all be a dead-end really, but, I thought it might be worthwhile to ask here to see what suggestions and advice might come up?

Thanks!

 

Ngreedia DRM basically.
The 6 core laptops ship with newer vbioses for the video cards that come with them. Trying to force flash an older vbios that was made for a "4 core" laptop chipset (like CM238 / Z170 equipped laptop boards) would cause a black screen on POST. At least if you tried flashing it with NVflash.

I don't know what would happen if you tried using a HW programmer to directly flash the card, bypassing NVflash, but from what I've seen so far, you still get a complete black screen. And I don't know if it's the Ngreedia DRM to blame or the System Bios to blame, or both. You would have to ask someone else.

And since all of the Z370 laptops (P870 TMx) Clevos all are 6 core laptops designed for 8700K's (9900K will be compatible with Prema Bios), modding the vbioses that come on the 1070's and 1080's is not supported since they are too new for the 1+ year old editor now.

Which really sucks, and why no one should even bother buying a 1070 system--only 1080 makes sense on the 6 core Clevos.

Same goes for MSI now. TDP modding a 1070 from 115W to 230W gives a nice 15% performance boost. Not enough to match a 200W 1080, but pretty close. But a 115W stock 1070 is just pants.

 

I was able to dump the GS65 GTX1070 Max-Q vbios through nvflash, just wanted to clear up something, I'm sure most of you are also able to dump the vbios through nvflash, yet to modify the TDP and to flash back requires using the SPI programmer, and not using the nvflash to flash back, why is that? Is there really some kind of digital protection that can corrupt the file or something? Or has something to do with the check sum?

 

Falcon protection. Very complicated with checksums and everything. Demonamic or whatever his name was (i think his site was voltground.com) had some charts showing the protection registers. It's very complicated. NVflash won't flash a modded vbios even if the checksums are completely intact due to the falcon protection. The HW programmer gets by that because Falcon can't block direct access. But the old vbios editor won't flash any video cards that came with 6 core laptops because the vbioses are too new. If you can load the vbios in the editor and you see the TDP target and limit values correctly, you can save and use the "presets" (required to change the "extreme power limits" which also allow the TDP range to work in the first place), then load the saved vbios and the changes are loaded, then it will work. If you get 0's for target and limit, then the vbios will fail.

 

You can try to flash vbios with nvflash by yourself and you get answers why isnt possible.

 

May I ask, did your vBIOS contain a UEFI section? Is it possible you could share it with me? I'm trying to find as many vBIOSes as I can.

 

The dumped VBIOS is 167kb. Can you check for me? See link please. Thanks!

Except the basic info, other things show 0 in the Pascal Tweaker though, guess we'll have to wait until @Coolane comes back.

 

Open your vbios i PT and hit PRESET, edit or save and reflash.

About GOP that's not present, grab GOPupd_v1.9.8.b and update your vbios. That things should work without any problem (for gt1030 that already have it works when I update to lastest version without addiotional modification).
https://www.win-raid.com/t892f16-AMD-and-Nvidia-GOP-update-No-requests-DIY-33.html#msg57124

 

When you load the GS65 GTX1070 Max-Q's vbios into Pascal Tweaker the Power target and the Power Limit show 0, does this have anything to do with the GOP?

However if you load cards working with skylake edition the power limit will show.

I think its simply that pascal tweaker is having some compatibility issues with the newer pascal card for the coffeelake edition. By the way, I thought a card this new doesn't require GOP patching?

 

Hey thanks for the link.

So, I've taken a look at your vBIOS in both rom-parser and in a hex editor. It's effectively identical to mine for the most part, except or some minor differences. Your vBIOS is 512 bytes larger than mine, which is somewhat interesting; but it contains no EFI BIOS.

I haven't really considered modifying the TDP settings in the ROM since my interests aren't really in gaming (I actually enjoy the Max-Q 'optmizations' - I just wish you could turn them off) but, it has been said the data in ROM is encrypted. I... don't see much in the way of encryption in these dumps -- but I don't have much basis for comparison. But if the ROM isn't "encrypted" or digitally signed then editing hex values and flashing it back shouldn't be too complex.

But if anyone else has any Max-Q vBIOSes or Coffee Lake vBIOSes that they can share please do.

 

Unfortunately, you get zeros in TDP and the "Preset" button doesn't work. The OP's first message says it's not compatible with "Coffee Lake" systems, which seems suggest the newer chipsets have a different type of ROM configuration so the TDP values may not be in the same location. This is speculative though, I'm still trying to figure out what's going on.

Hmm.. I've tried this, and I don't know if this creates a valid ROM or at least, one comparable to a stock GTX 1070 or 1070M with EFI. For example, of the vBIOS that I have that are EFI-capable, none of them start off with a BIOS header (0x55, 0xAA) but instead seem to start with (what I believe to be) an IFR header, and the BIOS header begins at offset 0xA000.

I'll try flashing the updated ROM to see if it boots; would be interesting to see if the solution were that simple, but when I've passed through the vBIOS to a virtual machine and run GPU-Z, it does not show the GPU as being UEFI enabled; which is not what I would expect if the ROM were valid.

I'll do more testing and report back.

 

I don't believe so. I think the TDP values are stored in the "BIOS" section rather than the EFI section.

Our cards definitely do not have a UEFI section. This section is marked by a header signature of (F1 0E 00 00), and have a PCIR Type 3 signature, in the second (or last) PCIR image; which is not found in the vBIOS dumps we have. Many suggest only that this is due to vBIOS Option ROM shadowing but I'm 99% sure that isn't the case since I've dumped the ROM using an SPI programmer and I've gotten the same dump from that as produced by nvflash. Looking at your ROM, I'd suspect your situation is identical to mine.

 

This problem could just be circumvented if the source code were released. Then someone could modify it for Coffee Lake 6 core laptops and even possibly make a Volta / Turing version too !

 

However if source code was released the cat and mouse game would be worse.

Is the software unmaintained?

Assuming the images aren't digitally signed (I don't think they are), it wouldn't be tough to duplicate the original "Mobile Pascal Tweaker." I'm pretty sure the functionality here is to just modify TDP values, and then provide a valid checksum at the end of the ROM is that not right? I suppose that'd be a first step to adding support for Coffee Lake systems.

 

Weird. For me your bios "works" in M.Pascal Editor like I said.


Checksums isn't stored anywhere. It calculated on data stored in VBios. MPeditor simply change checksum for (supported vbioses) to the same like before editing. You can manually change TDP in hexeditor and of course change Checksum manually also in hexeditor or use MPEditor to do it (need checksum of original files before modyfing).

Also (COolant says it on page20/60?) it removes beginning because some checks is in it. But for me removing that beginning the gt1030 (without checksuming or any other modyfying) card doesn't start at all.

Weird part is that is possible to update EFI/uefi with gop update and checksums of all data is changed but that image works fine.

Looks like vbios is divided in some modules and maybe that modules need to be checksumed separately? I tried add some data on the end (then checksums different to original) but card starts normally.

Even GPU-Z can read TDP in additional TAB, it reads correctly that TDP what i set manually in hex (but that in safe mode in 640*480 resolution with VNC connection because display stays black)

 

Yes no updates on it.

 

Hello, I've read all the comments from yesterday to today. It's cool. I want to turn to you. I have Alienware M18 R3, and upgraded to 1070. I'm going to unlock the vbios. I'm going to unlock the power to 151-190w. Should I change the value of def and Max from 16200 on page 2 to 19200, because I see two values of 16200. I hope you can understand my words. My English is poor. I really want to hear from you.

 

I am very glad to see you here. Thank you for your contribution to alienware18. I am now upgrading to 1070 like you. I want to know how much you have unlocked your 1070 power, because I am planning to unlock mine. I appreciate your answer.

 

I modified the tdp of my gtx 1070 to go to 150w, this was a bad idea on my part since the alienware 18 heatsink cannot withstand those temps even with metal paste on the die, you will reach 92c easily which is throttling temps. Also I started noticing black squares and artifacts showing up on screen, it became worse and worse. I lowered the tdp to 130w because frankly I don't want to kill another gtx 1070 I bought for my alienware, there not cheap!

So I would say stick to the default tdp the editor modifies your GPU to which is 130w.

 

Set default to 100W
Target to 200W
Tick adjustable
Test away without having to reflash every time, just use the power limit slider in afterburner.

Using 100 as the base means the Watts and %TDP / % Power Limit readings always match too.

 

That sounds like a much better way of doing it lol

i mod my heatsink ,so my 1070 is under 50c 。

 

Changing 16200 to 19200 is required if you want to exceed 200W on the Limit field (16200 limits you to 200W maximum).
However there are some...driver or hardware oddities which may be due to the specific MSI 1070 vbios and how the original MSI 1080 was first made for a 150W target, rather than a 200W target.

Some games will power throttle at 150W instead of 200W, even when you selected 200W in the MSI Afterburner slider, when they should be reaching 200W first. PUBG has done this. Changing 16200 to 19200 stops this, but if you set, let's say, a 230W limit, PUBG may still throttle sometimes at 200W instead of 230W. I have not seen this behavior in Heaven or Valley or anything else.

One thing i did notice is changing this first extreme setting changes the point where the system throttles the GPU on battery power. This can cause excessive GPU load on the battery.

 

i mean if i should modify the range 16200-16200 to 16200-19200 or 19200-19200.
in other words, the extreme fitst def value and max value need modify 16200 to 19200 both?or only the max value do.
sorry,my english is poor.
im glad to your reply.

 

Extreme power limits doesn't have a 'range'. You enter a value.
Also there is no documentation for these settings. Because these settings if changed randomly can destroy your hardware.
I believe that "extreme" settings have to deal with "Amps" or "Current" going through the PCI-E voltage rails, for different power states. At least from what I remember on the "Maxwell/Kepler" desktop vbios editors.

I also believe that the early "power limit throttling" in PUBG is because of a bug in the MSI vbios. Possibly again due to some relation between power limits and the extreme power limits.

As you know, the default setting for "GTX 1080" extreme power limits is "16200"
For MSI GTX 1070 its 14,500.(i think).

To get TDP higher than 125W on GTX 1070, you need to change the extreme power limit to 16,200, which is the default for the GTX 1080. The problem is, the GTX 1080 (MSI) has 2 versions: a 150W and a 200W card. In fact the original (pre-release) MSI 1070 MXM had a TDP of 150W too. So the way the extreme power limits were coded, were based on the 150W version. The 200W version uses the same settings, but it seems (again, there is no real documentation of these settings) that the 16,200 and the vbios itself was 'calibrated' for 150W somehow. And PUBG manages to somehow flag this and cause power limit throttling if you exceed 150W, even with the TDP set to 200W. The 19,200 value "solves" this, however the 19,200 value is made (at least in the GTX 1080 "preset" button) for EXCEEDING 200W (example: 215W target, 258W limit). But again, sometimes PUBG flags power limit at 200W. I know the "2nd"" extreme power limit also has to be increased (like done on the preset), but again I dont know what relation it is for.

For example:
default for GTX 1070 (MSI) is 14500, 181000, 76700 (115W).
Preset button changes this to 16200, 242000, 137600 (151W-170W). These extreme power limits are the exact same as the defaults for the GTX 1080 (MSI).
This is good up to 200W, but sometimes PUBG flags power limit at 155W+.

Default for GTX 1080 is the same (16200, 242000, 137600) (200W).
Pressing the preset button only changes the target/limit to 215W-258W, and the first extreme power limit to 19200, not changing the other two.

Yet regardless of the target/limit setting, PUBG seems to sometimes throttle at 200W. "sometimes".
I haven't seen it do it lately since the last huge patch but I haven't played PUBG in a few months now.

This isn't repeatable either. It seems to do it when it wants. Sometimes at a certain GPU temperature. Sometimes when looking at certain walls. I don't know and frankly I don't care

Just remember there is no harm in using "19,200", unless you are on battery power, as I found (AGAIN, NOT ALL THE TIME), that sometimes a GTX 1070 gets limited to 65W(!) on an 80W battery, which trips the system and it shuts off (it should be pulling no more than 50W).

And please don't mess with the other two extreme power limits. We don't know what they do exactly. Bloodhawk does, as well as Prema and a few others, but they are not going to tell you. Because you can seriously destroy your cards.

 

Thank you very much for taking the time to reply to me. Do you mean that the value of position one and position two should always be the same all time?
Another question: why the score is higher when i raise power? i can't increase the core frequency, or the test will crash.it seem +150-160mhz whatever 150w or 200w.

You can add me on Wechat. Falkentyne. (I am not chinese, so...yeah).
I'll reinstall it when I'm not lazy. Right now I'm lazy.

The score is higher when you raise power, because you are not "Power limit" throttling. Power limit throttling causes the core clocks and voltage to drop when you reach the power limit in watts. This is of course for the "TDP slider" in MSI afterburner or the "Target/Limit" values.

At lower TDP, you can raise core clocks higher, but you will just throttle more.
Example: at 115W TDP, you can often do +250 mhz on the clocks. Because you will be throttling so much, the card will never reach 2060 mhz, etc except at very very light load or very old games. If you raise TDP, the card will throttle less, so it will reach higher clocks, but then it will be unstable because the offset is too high for the new clocks.

Again there is no documentation for these Extreme msettings. Leave them at the same values for def and max.

16200/16200 is good up to 150W. (in PUBG). Good up to 200W (not in PUBG).
19200/19200 is good up to 200W in PUBG. Good up to 262W (not in PUBG).

Someone should just spill the beans and explain what relation are these "milliwatt" values to rail amps.
I mean, 19200 is 19.2 watts, 242000 is 242W, 137600 is 137.6 watts. That is if the "mw" means milliwatts" for each one.

You might have more success looking over on overclock.net for the two "Kepler/maxwell bios editor" threads. The only hints shown are "PCIE rails".

 

I see. Ha ha, I have sent a request to add a friend to WeChat, and you can agree to it when you want to.
The liquid cooling is modified on my alienware18, so the card temperature is always below 50 C,but i get 20000 graphical score at most.
Next, I'm going to change 19200 to 16200, that is, the default extreme frequency, and then test the performance.
I don't play pubg for a while. It consumes too much time. Maybe I will test the performance to play.
