Razer Blade Pro 17 2080 Max Q Vbios

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.
