Razer Blade Pro 17 2080 Max Q Vbios

Have you overclocked your ram?

 

No just the stock that came with the blade. But I’m thinking that he was using stock ram as well? Or maybe I didn’t catch that.

Mine is the stock ram, if I decide to keep this laptop I'll be putting my 64gb in it, so not going to work on optimizing ram right now. All cores boost to 4.0GHz and hold steady without temp issues on my blade.

The only real mod I made to the clocks is to lower the base clock to 1.6GHz. The TDP mods are the ones recommended in the "Take full control of your Razer without PL...." thread

 

@Hackintoshihope what temps are you getting on your blade? What apps are running in the background?

 

I tested out a 190W vBIOS this morning just to see how it would go. Flashed fine, no Thunderbolt or mDP output. Definitely runs up to 190W, definitely increased GPU temps. Didn't see any performance gains, but haven't taken the time yet to try to mess with the performance curve to keep temps and power down, but get additional performance. I actually tested several 190W vBIOS, this is the only one I could get to work.
*UPDATE*
After uninstalling with DDU and fresh driver install, mDP and HDMI work, still no thunderbolt out. To keep the power lower, I changed the core clock curve to 1600MHz @ 725mV. Runs @ ~140W, but performance is almost identical to the 90W vBIOS.

Could you share the vbios? I'd love to tinker with it

 

Because this has a high potential to damage someone's machine, I've PM'd you a link. What I ultimately concluded is that we are being limited by Voltage. There must be something deeper than just the vBIOS. Whether on the 80W, 90/100W, or 190W, when I run Firestrike, it generally will run between 700-800mV, and to get the full power of the 190W, we would need to get higher than that.

 

Black out the vbios version in the screenshot to further protect users. I found it with that information.

 

Actually, when running non maxq vbioses, the gpu goes into safe mode which restricts voltage to 0.7v and clocks to 1350mhz.

 

Possibly however I think what these vbios (the ones that work) are doing are allowing the card to pull the most amount of power possible for the machine, then it triggers safe mode. However what the vbios does allow is the memory clock runs higher and its allowing me to get 23,500 GPU score. You should try it and see if it improves your score to the 23,500 level.

 

You tried the 190w vbios?

 

Yes I can pm you a link. I’m hitting non gaming clocks of 1900 MHz overclocked. However while gaming I am locked at .7mv.

Sure, send it over please

Do you have the gpu z screenshot?

 

Just flashed it, clocks look slightly higher. The gddr6 is a lot more overclockable though. I maxed out the slider to +1500mhz no problem though it doesn't look like it'll match actual 150w 2080s.

Will run benchmarks later.

 

Yes I think our memory is getting the desktop voltage. Also what memory do you have? I’ve got Samsung haven’t gone much higher than +550 will try to now.

Samsung.

I've asked for the 200w vbios from the GT76 Titan but no news yet. Will be interesting to see how that performs.

 

Some of those just straight bsod but like I said this one gives the most performance so far. See what your fire strike graphics score is.

Oh yeah, I forgot to ask. What power draw do you measure from the wall this time?

 

230W compared to the 190W to 200W with the 100W vbios. It seems that the 190W (GPU only power draw) is still a lie but there is an increase of 30W to 40W increase for the GPU.

 

Is 230w the limit for the power brick?

 

230W is so we are getting pretty close. It should pull more technically (some have said they can go past spec) but seems like I’m hitting power limit on my brick. So it is possible you should get a little more performance? I think you've got a larger power brick?

 

Unfortunately not, mine is 230w.

 

Got a small 800 point boost to gpu score in firestrike

Metro exodus benchmark with the RTX preset got a nice boost from 52.34 to 56.37

Since Ray tracing is known to like fast memory I guess this mod gives a boost where its needed most.

I dialed back to +1200mhz mhz for now, at +1500mhz there is a performance drop. Probably due to error correction.

 

This is inline with what I am now getting I get a few hundred points more at 23,500 but you are getting a nice boost.

This the score is with a +750MHz

This is the score with a +1040MHz and a box fan blowing underneath
https://www.3dmark.com/fs/20413173

Also usually stability in all titles with Samsung GDDR6 is about +1000MHz to 1100MHz

 

Increased my ram frequency back up to 3466mhz. +190core +1200 memory

 

Are you using XMP?

 

No. Msi laptops natively support overclocking.

 

I’ve enabled memory overclocking on my Razer but I can’t get anything to stick. I might need to get some better modules. It’s so funny that Razer locks down xmp in the bios lol. It was easy to enable but such a silly thing to do.

How are you getting into the Memory Overclock menu? I've tried everything BIOS mod wise on this RB15.

 

I did more testing with the 190w vbios and it seems like power efficiency fell off a cliff.

30-50% more power draw (actual) and more heat for 5-8% more performance doesn't seem right. That would put efficiency on par or lower than desktop chips. Somethings not right.

 

We are throwing efficiency out the window with the higher memory clocks and higher sustained power consumption. But I still believe the perceived 190W draw is not correct as I’m seeming only about a 20-30% increase in power. Along the lines of 120W to 130W. It’s the price we pay I think.

The thing is, that shouldn't be happening. 130w should still do better in terms of efficiency than 150w chips.

40w more power draw for 5-8% just doesn't make sense. That would mean nearly all the increase in power draw simply went into generating heat.

 

That makes sense but could it be that that has something to do with our poor vrm design on these Max Q laptops? Or just something wrong with the vbios and not configured correctly for our machines?

Vrms can be ruled out. The A51M will still draw more power per phase than my GS75 even if I could make it draw 150w. And the mosfets used on both are the same.

So unless manufacturers go and extra step to cap power draw on a hardware level, there shouldn't be any problems hardware wise.

For now I think there's something wrong on the software side. Something to do with the gpus identifying as Max-q regardless of what vbios is flashed.

 

@Hackintoshihope can you try limiting the cpu to 35w or less to see if it allows the gpu to boost higher with the 190w vbios?

I just ordered a power meter so I can't accurately assess at the moment whether insufficient power from the adapter is to blame.

 

Not 100% sure how I would do that? I am assuming I would need to tweak my bios to heavily limit it? The tweak i used is in my signature. "TDP MOD"

 

You'd need to revert the tdp mod first. Then change the turbo boost short power max and turbo boost long power max to 35w in throttlestop.

 

That is not really how it works. You can bet on it that the A51M mosfets are cooled better than in the GS75 and even then they arent cooled enough in the A51M. That is one of the reasons why they pooped so often.

 

The cooling solution on the A51M is a passive aluminium heatsink. The GS75 has a dedicated heatpipe connecting the mosfets to the heatsinks.

I also read from one user that the thermal pads of the A51M were making poor contact with the passive heatsink anyways so the heat wasn't even being transferred well in the first place.

 

The heatsink of the msi is already at fairly saturated and even more so in the razers where they are only covered by a thin copper sheet as part of the vapor vaamber (but not vapor chamber itself}.

The aluminum heatsink does far more than for both other laptop models.

The thermals are already at the limits in the blades.

 

I have no way to confirm that but I could certainly see it being a problem on the razer if it only has a thin copper sheet to spread heat from the mosfets.

As for the GS75, I seriously doubt it couldn't handle a few more watts, in fact I think it will be able to handle a 150w gpu load just fine, which is why I'm looking for higher powered vbioses in the first place

 

I have the Blade 15, and it is just a 2mm thick copper sheet on top of the VRM's. It is part of the whole vapor chamber ofcourse, but that part isnt hollow with liquid inside.

 

With the right settings I find it hard to get over 70 degrees on the graphics chip - isn't it rated for 100 degrees?

 

The GPU touches 77c in my unit. 2070MQ.

But I mean the mosfets, those are already run very hot.

 

In this RB15 the CPU is rated at 100 degrees, critical is 119. GPU is 95 and never reaches 75 ... I think there's plenty more room for TDP unlocks here.

 

Again I am talking about, the power delivery surround the CPU and GPU. Overclocking the GPU means putting more strain on the VRM mosfets because those have to work harder and push more power. Those are configured for a certain load and cooled for that load. Putting too much stress on those can cause a litteral burn-out. In general mosfets arent monitored in laptop when it comes to heat.

Intel CPU's are rated for 100c yes, but it isnt good long term, same goes for the GPU. A rule of thumb is that every 10c degrades the lifespan by half.

 

I just finished testing it myself. The power brick isn't the limiting factor.

Here are the average readings measured from the wall.

Stock
Idle/light tasks -20-50w
Far cry 5 - 175w
Far cry new dawn - 170w
Unigine heaven - 155w
Metro exodus (rtx preset) - 160w
Prime 95 - 110w
Prime 95 + Unigene Heaven - 220w

190w vbios
Far cry 5 - 210w
Far cry New dawn - 205w
Unigene heaven - 185w
Metro exodus - 190w
Prime 95 - 115w (margin of error)


I didn't test prime 95 + Unigene heaven as that would almost certainly go above 230w and I didn't want to fry my adapter. Nevertheless some conclusions can be made.

The 190w vbios draws 30-35w more than the stock 90w vbios. However, it is running at a lower voltage which means it will be drawing a lot more current.

Seeing that none of the games reached 220w which the adapter is clearly capable of, we can conclude that it is not the limiting factor here.

What I think the limiting factor is right now is the mosfets. At 0.7v it's probably hitting the max sustained current output.

So the problem right now is still the gpu running in a safe mode of sorts which limits the max voltage to about 0.7v . That is why we are seeing horrible efficiency with the 190w vbios. The gpu doesn't scale with current, it scales with voltage (at least until +-1v). For reference a 150w 2080 normally runs at 0.88v

Will do more testing to see if I can learn anything useful.

 

Excellent information. I’ll do a similar right up and compare out systems and see if I have the same results.

Just read a page on ultrabookreview.com and it seems like asus will also have a 100w 2080Max-q laptop



Though it will definitely be very hard to track down an owner.
