Razer Blade Pro 17 2080 Max Q Vbios

For the GS65 1070 Max-Q the heat of the mosfet is transferred directly to the side heat fin of the laptop, when I increase the TGP, the side does get significantly hotter, however this type of mosfet can withstand up to 125C, not sure about the long term though.

In order to keep it at 77C max, I have it set to 93.6W at max using power slider.

 

Power slider?

 

Well, currently RTX GPU still can't do the vbios modding, but Pascal GPU can accept the modded vbios through hardware flashing, and I flashed mine.

I'm just saying that I was able to clearly feel the heat of the mosfet just by touching the side fin and I did find for every increase in 10W, the temperature of the side fin which is linking to the mosfet gets hotter and hotter.

 

components round it and the PCB itself dont like the 125c. Also thats for peak temps not long term.

 

Surely as it says "Performance Limit - Power: Yes" in HWINFO that means that you are not hitting 100W ...

 

That is an uneducated answer... performance limit power means you are hitting the specified tdp... power is never unlimited if it were a GPU would never stop boosting until it hit some kind of other limiter...

I've been experimenting with flashing normal gpu vbioses onto Max-q parts and ALL off them exhibit the same behavior.

Even a 1660ti Max-q (60w) can't be flashed to a 1660ti (80w) although the increase in power draw is very small.

It seems like something is fundamental different with Max-q gpus. But what?

 

I guess NVIDIA saw what's coming from users' side.

 

COuld be just purely that it measures the VRM circuit if it has the power. Limit it through that.

 

Uneducated we will agree on! But when my 1070 MaxQ hits 90W in HWINFO while playing Battlefield V it backs off the Core Clock by a few MHz to remain under 90W - what is the point in pushing the card like this in a gaming scenario, surely I gain 0 performance if its hitting into PL over and over and unable to achieve a stable clock? Maybe I am misunderstanding something fundamental here.

 

Unfortunately

 

It happens regardless of VRM design. The zephyrus G and Zephyrus M have the same vrm for the 1660ti but one has a Max-q 1660ti and the other a full 1660ti

 

I’m not exactly sure you understand the implications of sensors etc. I’m using about 120W to 130W TDP but depending on the load, cores, memory load. That TDP is going to be spent in different ways meaning it might have to reduce your clock for some other function of the GPU. But overall the higher tdp the higher performance you can and will hit due to the increased power budget.

Example... Car has 400HP however if you use the A/C system you might now only have 375HP for your car to actually move because 25HP is being used to power your A/C. Hope that helps.

If my card is limited to 90W then what do I gain from pushing it so hard it throttles back from 90W?

 

I’m confused as to the question... it is being forced to always stay around 90W software is preventing it from going higher so it can only go as high as 90W?

As with mine I’ve forced it to go as high as 120W.

Just running the stock 1070 MaxQ in a RB15 - it seems to pull 91W+ when trying to run @ 1600mhz playing BFV, voltages between 0.800-0.825 ... I just wondered should I be letting it hit the PL or is that affecting performance/FPS?

 

Just posting to add some more data; went from the 80W stock which was leading to:

http://www.3dmark.com/fs/20645284

To the 100W one (which, in games, lets my GPU sit at around 90W for 95% of the time with jumps to 100W for a few seconds):

https://www.3dmark.com/fs/20652688

As I don't want to see anything higher than high 80s on the CPU and low 70s on the GPU I'm still using the PL CPU and n OC except the gaming mode on Synapse.

 

Based on your 3dmark score, the power limit is at 90w

Not sure how the 100w vbios should work but @Hackintoshihope mentioned something about the 100w only coming into effect at lower temps if I remember correctly.

 

Recent nvidia gpus always hit PL when cooled correctly. Its just an imposed limit and the performance you get. The only thing is with MaxQ you dont have the ability to move that power slider up for more performance.

 

The power slider has always been locked for ALL laptop gpus actually. Not counting the use of the pascal tdp tweaker that is.

 

That is only since pascal and not on all models, there are laptops where it has been unlocked. But even unlocking it in bios doesnt seem to do anything from what I can gather when it comes to MaxQ.

 

But the question still remains: am I losing FPS letting my card hit into the PL and remain unstable? Surely I should undervolt it to hit 85w max so it's more stable?

 

Nope, no GPU stays perfectly stable with its clock and it is also dependent on whats on screen. Undervolting can mean in this case that it cant boost as high to begin with and start power limiting at 85w.

 

Now I'm more confused than ever

What benefits am I gaining from messing with the voltage curve in Afterburner?

 

You will be getting the same performance but better temps since you will be running lower voltages.

It's similar to overclocking but instead of increasing clocks at a set voltage, you are decreasing voltage at a set clock.

 

It can go 2 ways, if your GPU is abl eto run at lower voltage, you will basically undervolt your GPU and in return the same performance with lower temps. But if the GPU notices that it cannot keep its clocks at said voltages, it will start downclocking. Thus the undervolt will act as a new power limit. Testing this is a lot of trial and error. It doesnt help that clockspeeds on current Nvidia GPU's fluctuate quite a bit.

 

The one I flashed is exactly the one you posted at page 4 or something alike.

He said that, but than mentioned that it wouldn't be the case as he was throttling even in freezer.

I may try reinstalling Synapse just in case some update is then provided to me somehow, as @Hackintoshihope mentioned some update after his RBP vBios flash, I think.

 

Bios 1.04 allowed me the constant 100W power draw while out of the freezer with synapse high performance mode.

 

My unit was produced in August 2019, it came with everything updated BIOS wise; Synapse isn't pushing updates also. I don't know what'up with my unit then.

 

can you please send me the 190W and maybe the 150W and 100W BIOS, too.
That would be really nice. I have a RB15 with 2080
I´ll post my results and of course make a donation

 

i did the pl tweak on the bios but cannot exceed 3.9 ghz on all core boost. can you tell me what the 4.0ghz mod is?

 

8750h will cap out at 3.9, 9750h will cap out at 4.0

 

Hey guys, trying to follow this thread, from my understanding there is a 150w and 190w 2080 max q bios? I actually installed the 100w bios which was on this thread, but it was the same bios version as the version my Razer pro 2080 max q was running. Is there any increase using the 150w or 190w bios? Happy to sacrifice some heat for performance as my GPU sits around 67c most of the time while playing MW . Cheers!

 

The 150w bios outright doesnt work. It just raises the gddr6 voltage and clock but the gpu is locked into safe mode and wont go above 1350mhz.

The 190w vbios somewhat works but im not sure how high it can potentially go as i get limited by my 230w ac adapter when using it. The increase in gddr6 voltage and clock seems to use quite a lot of power which takes away some power that the gpu core can use.

I went with the most dangerous but surefire method which is to do a shunt mod and completely remove the gpu power limit. And since i am still on a max-q vbios, the gddr6 runs at lower voltages and clocks which lets the gpu get all of the extra power. I havent done much tweaking aside from locking the clockspeed to 1860mhz with a +160mhz offset. Now it performs like a stock 150w RTX 2080 mobile.

Do you think it be possible to shunt mod the RTX 2060 in the same way?

I toyed with the idea of flashing a higher wattage VBIOS with a CH341 programmer ... will that yield the same kind of results?

 

Oh its definitely possible. But are you willing to do so?

If I were you I'd wait for the 115w 2060s to drop and try flashing those vbioses first. And you can just used a modded nvflash for that, no need for an spi programmer.

 

Oh wow, when did that become a thing? Any ETA on the drop?

 

https://www.notebookcheck.net/Nvidi...along-with-the-new-Super-lineup.460740.0.html

Should drop this or next month.

 

Hey @seanwee can you go into more details on how you did the shunt mod and where its located on the RB15 motherboard? I would like to do something like if its not too complicated.I have the 2070mq and do you think it would be wroth it?

 

First things first, how are your soldering skills? Laptop shunt resistors have pads underneath the shunt and not all around like on desktops so you'll need to be careful not to heat up the shunt resistor too much when shorting it.

I'd be happy to help you find the shunts on the razer blade 15 if you can take a high resolution photo of the motherboard (clear enough to see small printed text).

If you don't have a high enough resolution camera, look for anything that says R005 near the gpu Vrms, they can be on the same side as the gpu or on the other side. They usually come in a pair so if you see two R005 shunt resistors in the same area that's usually it.

 

I dont have mush soldering skills so probably to risky for me to do. Ill get back to you with those pictures, really interested on how its done and the benefits of it. Thanks

 

Nothing special really, essentialy it's just short circuiting a sensor.

Think of it as hotwiring a car, or shorting a security panel so you can get in.

 

Okay ill look up some videos, yeah that doesn't sound too hard to do. Im willing to do almost anything to increase performance lol. Thanks

 

Its not hard on desktops, it's harder on laptops if you don't want to damage the shunt.

I can remove the mod and have it looking as good as new. That's the hard part.

As far as I know I'm the first one to be insane enough to perform the shunt mod on a laptop.

 

Yeah I bet you are and you your getting great performance out of you laptop. You should make a guide or something cause you seem to know what your doing and could help others.

 

Haha someone on reddit asked me if I was going to start a cult as well after seeing my firestrike and timespy scores there.

 

Holy god XD that is amazing I’d be curious to see pictures of your board and see how clean it looks compared to stock. But all in all amazing performance out of it, but I’m assuming the amount of heat it outputs is insane?

Running firestrike the gpu gets to 77°C with cooler boost. I'm using carbonaut with a lapped heatsink though.

I didn't take a pic and I likely won't be taking my GS75 apart for a long time as I'll have to replace the carbonaut pad which is fairly expensive. And right now the temps are awesome.

It just looks like solder on top of a pad. The surrounding pcb is a bit yellow from the flux but that can be scraped off.

Oh and by the way, I've surpassed the scores I posted back then, check my signature for the links.

 

Do you know if I could cheat and use liquid metal on the top of the shunts like on for example an RTX 2080 Ti? To see if I’m going to get those kind of performance numbers? Also if I’m not mistaken I think your cooling surpasses ours in the 15 inch Razer Blades?
