Rise your 2080 mobile with 200W from vbios of 51M

Hi everyone.

I try to flash my 2080 with 200W vbios of 51M and I am very surprised with results.
In Fire Strick graphic, my score was increased from 24K to 27K same to Asus 2080 desktop OC.
This is my score:

My laptop is Clevo P751TM1-G.
If someone has the same GPU, let try it to get a more exciting feeling.



Thank to @DaMafiaGamer for his 200W vbios

be VERY careful with this, we are talking about two completely different board designs here. if your card dies after some weeks/months of use, please remember this thread and dont scratch ur head thinking it had something to do with bad luck

just saying!

Oh of course. There are a few cases that have run 200W on BGAd cards and they are still satisfied with that. For my case, I know what I'm doing and take responsibility for my actions

 

with that out of the way: good job

How are temps while gaming with the 200W vBIOS?

 

Aound 83-84 with mx4 themal paste and no lapped heatsink

 

Interesting. That's not bad at all, similar to my 190W 1080N with LM actually. I guess the much larger TU104 die really is significantly easier to cool.

 

2080 die is 545mm2 larger 1080 die with 314mm2. So I think in the same power, 2080 cooler than 1080.
I am thinking about lapping heatsink and use liquid metal. Maybe the temp can reduce to 7x C

 

The thermal density is a bit lower.

 

That's a pretty nice boost your scores. A note on LM, its a good idea to testfit the card outside the chassis to check the die contact. Sometimes you either need a thinner 0.5mm copper shim for the die or thinner thermalpads for everything else.

 

Hi pro.
I would like to delid 9900k and remove ihs to contact directly heatsink to CPU die. So I want to use copper shim and solder it to the heatsink by Sn42/Bi58 with low melt temp (138C). Do you konow thickness of this copper shim. I am thinking 2.0/2.5/3.0mm but do not know how much thickness is reasonable? Hope you can give some advice .
About copper shim for gpu die. I am thinking between 0.1, 0.3 and 0.5mm. But I also don't know how much thickness is suitable

 

Direct die would be tricky. As a part of the heatsink has a protrusion for VRM cooling, you would need to take that into consideration for the shim thickness. I see a few issues could end up happening, you either get too much pressure on the die or not enough. Both bad if you don't get the proper thickness. Soldering a shim would also affect mounting for everything else as its a unified heatsink.

I tried something similar, this was without soldering but to test a more "direct die" type of cooling with a couple copper shims and no ihs. Temperatures ended up worse, as the 8-core die is very dense and resulted in a hotspot. Where the heat was mostly carried by a single or two heatpipes, instead of all 4. This is why you want an IHS, as it helps to spread the heat over a larger area.

But theoretically, if you have a shim that has a large enough surface area similar to the stock ihs, 29x29mm at about 4mm, you might get decent results.

From my own testing, I found that a taller IHS was the better solution, as it increased the contact pressure improving temperatures significantly over stock and othe copper ihs.

 

You would need to remanufacture the heatsink and shim the package of the CPU to ensure good contact with the pads and pins in the socket.

 

sounds like more effort that its worth haha. Especially since its already operating at a decent temp fully loaded/overclocked.

 

Even in the desktop arena it's very uncommon.

 

This is awesome! So the Clevo RTX2080 runs ok with a Dell 200TDP 2080 bios?

 

hey what kind of performance can a power modded Clevo GTX1080 get running LM and a lapped heatsink? Can it get close to this? I’m weighting my options. Tempted to get a RTX2080 lol.

My LM and Kapton tape and shims will be here today. But I’ll still need a programmer and 1.8v adapter etc. etc.

 

You will be looking at linear scaling to between 50-80% scaling. So 10% extra power for 5-8% scaling normally.

 

I'd hold out until q2 when 3xxx series mxm cards drop, to see performance increase..

 

2nd hand might become more of an option too.

 

You think Clevo will keep the same MXM design we have now?

 

Thats assuming they even support it on 2018/2019 platforms haha

 

Fascinating!

I have the P751TM1 from HIDEvolution, would be very interested in flashing this VBIOS.

 

Successfully flashed.
Almost had a mini heart attack when the screen went black haha.

 

Hey what kind of performance gains are you getting?

 

A bit close to what you got.
For some reason (drivers, perhaps?) my fire strike score is about 1k lower than yours.
Compared to previous results, the gain is substantial. A few hundreds of points above what I had, will need to confirm the exact scores when I'm back on the computer.

Currently setting up a new router in the basement :-( at 0137 am.

 

Not me lol. I’m running a Clevo gtx1080. I don’t have a RTX2080. I am considering buying that upgrade kit off eBay from Eurocom though.

 

Hey could you guys run some in game benchmarks or post more information about this 200 watt bios?

it looks like a Clevo 190TDP GTX1080 OC is only about 20% slower than a RTX2080 with the 200TDP bios mod.

 

Sure thing.

A few notes: I've seen peaks of up to ~170W when running Blender with Optix (on Ubuntu) using the BMW benchmark sequence(s), and then settles back to 150W.
Thermals, in any game, do not go above 84 degrees for whatever reason. Even in BF V where I had initially seen spikes of up to 87 degrees with the stock VBIOS.
Another hint: to flash, you'll need to pass:

nvflash.exe -6 'vbios-to-flash.rom'

Because the PCI ID of the VBIOS differs from what's on the card. Expect your screen to turn black.

 

84C will be the thermal target.

 

I reverted my GPU firmware to stock, for one reason: I noticed that under heavy load, the GPU's sustained power draw would drop from the usual 150W to ~117W, and in one specific title, Battlefield 1, I lost about 14 fps.

Flashing back the original VBIOS restored the performance to normal.

 

It could be worth checking the VRM cooling is snug.

 

What's the maximum sustained power draw that the MXM slot on this chassis can withstand?

 

It should be able to cope with the draw of the 200w vbios, thermals are more the limit.

 

PCI-E is typically rated for 75W with the rest of the power coming from power connector.

 

PCI-e specs do not apply to mxm.

I've had 980m cards drawing over 200w each from the slot.

That would kill any desktop board.

This bios work in Clevo RTX2080 ?
90.04.3B.00.79 ?

 

See the first post with a clevo card.

 

I see but i don't know this bios i Compatibile with this revision or revision with G-Sync

 

So did it work on my card ?

 

What revision on your RTX 2080 you have ?

 

Any source for 170w or 180w Bios for clevo RTX 2080? 200w is too much

 

Is there a similar solution for RTX 2070 BIOS? Maybe someone can share?

 

Hey , i have a rtx 2080 mobile also . can you give me the base video bios ? i think i bricked mine .... and i can t find a compatibile bios ... i have de g sync version of 2080. ... also do you think the 150w it`s ok ?

 

Do you have the vbios for rtx 2080 mobile 150 w with g sync ? thx

 

Flash any bios for clevo mobile RTX2080 with version ending with .7A

 

i tried all ... nothing ... it `s a black screen and after 4 sec it`s shutting down ...

 

Are you using a tool to flash the chip?

 

I did this . With all bioses that i found with this ending .... 7a . Is it posibile that the bios chip fried?
