2070 moblie

[CatXice]

So I have a laptop with a 2070 in and as far as i am aware its full desktop chip with its clocks and power pulled back.

 

So little bit of back story i was trying to get a little juice from it and i found were its limit was on clock speed when it would crash on heaven and pulled it back a touch and left it running for 30mins to see if it was good and stable to which it was happy days.

 

So then i thought well lets see why its crashing voltage limit was of cause the problem. With the clock speed set any higher then 1625 it would randomly try and pull a little over 1v from the mxm slot and clock up to 2200 and thats when heaven would lock up and close. Which i thought was odd to say the least.

 

So normally running at 1625 would be pulling 800 to 840mv.

If i set the clock to 1635 it would run like this for maybe 5mins and then try to pull like 1v and run at 2200 and cause heaven to crash anyone know why it would do this just thought it was interesting.

 

Side note at 1625 840mv pulling around 115w +/- 2w total board draw.

 

Have a snoop about on google i believe the 2070 moblie should have a a max draw of 115w (the sorce i found didnt say if that was chip or board draw but considering my findings so far going to say its board draw).

 

Now the interesting thing here is that the same source also said the 2080 moblie had a draw of 120w so we know the mxm slot can take 120w so would it be possible to get 120w from the slot on a 2070 getting it closer to its desktop brother in performance or even some how bypass this limit all together and have a full size 2070 in a laptop. Now i know the pcb would not be rated for the full power a desktop 2070 could pull put if you had the time and gear could there not be a way to solder onto the chip terminals to give it the extra power it wants to run at it full performance?

 

Just a little something to discuss? And for some nutter with more money then they know what to responsible do with to try hahaha weres linus when u need him....

A note on the whole “same as a desktop chip” thing:

Spoiler

A “full desktop chip with clocks and power pulled back” is what a 2070 max-q is as well as other mobile 2070s. My memory is the actual power is in the desktop 1650-1660 range. Someone may have fed you marketing.  I once heard a ring described as “gold but cast hollow and the space filled with another material”. Which is what gold-fill actually is, which is one step above gold plated.  The trick with that one is that the gold can be cast really really really thin.  No more gold is really actually used than gold plated but it looks better.  More work though. The trick with this one is a chip clocked back enough isn’t actually any faster than an earlier lower end card. Also a GPU card is a lot more than the gpu itself.  There’s VRM and all sorts of stuff.  Even if you somehow got 150w into that tu104 somehow it doesn’t mean it would run like a desktop 2070. It would probably blow up or melt or fail or something long before then.  

A note on messing with laptop power:

Spoiler

Laptops often have funny power supplies and their GPUs and CPUs often have really severe cooling limits.  Overheating usually happens befor drawing too much power but with laptop power you never know what you will run into

Cooling is not an issue for my laptop only hitting 65c on cpu and gpu even with an oc

 

And the whole trying to push more power into it is more of a theory not something to try haha but pulling more power from the mxm slot would be a more realistic thing to do as the 2080 card has a high power draw then 2070 so we know the mxm slot can take it be interesting to see if more voltage could be pulled through it and make a 2070 moblie run at a higher clock
