2019 RB i7-9750H, 2080 Max-Q, & 240 Hz!

Received this monster yesterday! So far I am sitting at a -.150v undervolt with temps never going over ~84 in any of my stress testing/hour gaming sessions. I have been using multiple testing methods, including Aida64, Heaven 4.0, and Prime95. Games being played are the Witcher 3 and GTA V. Any tests that anyone would like me to run? Or any advice? I did play around with afterburner but decided i don't even really want to OC my gpu.

 

That's nice temperature, can you run 3dmark like firestrike? It'll be nice with hwinfo screenshot like this, while running it.

 

Gladly! Here is a screenshot taken right after the test finished


and here is a link to my test results - https://www.3dmark.com/3dm/36674999?

As you can see, I did end up dropping the undervolt from -.150 to -.135. I did this due to some BSODs I was getting previously, however i dont think they had any relation to the undervolt i previously had, as they went away after i fully uninstalled the NVIDIA driver using DDU and then did a manual reinstall.

 

I noticed that when I have Razer Synapse uninstalled, my Graphics score consistently sits around 21k and my Physics score sits at just above 15k.
However, when I have Razer Synapse installed and on the performance mode, my Graphics score drops to sub 20k and my physics score jumps to just under 17k.
And this is after over 20 tests of this theory... Any idea why this might be?

 

Synapse maybe holding the gpu boost clock but it doesn’t matter you can use afterburner to boost it by increasing core frequency, the important one you can get better cpu performance which probably without Synapse it sits on default (balanced) tdp, maybe 25 watt (i don’t have your model but on 2018 it sits on 25 watt on this mode) which explain your lower score, on performance mode it’s maybe higher like 45 watt which showed on that HWinfo64 sensor.

 

That makes sense. Well I am definitely slowly dialing in on the tune for this machine, my last Firestrike score is here - https://www.3dmark.com/fs/19536975

This is with a -.140v underclock and a +130 core +450 memory overclock in afterburner. Temps are still the exact same.

 

Yeah I would also put thermal number one on this thin light but look at that 3Dmark ranks apparently some other Razer laptop can sit on the top 1080mq, 9750H system but your physical score is better, it is probably a Blade Pro with gpu silicon lottery for better max OC value.

 

Agreed. I will tune down the GPU overclock as needed if temps ever get above ~86/87c during intense sessions. So far i haven't seen that but time will tell. And yeah how the hell did that person get such a high graphics score? You think luck of the draw gets an extra 2k score? Or maybe they know something I don’t lol... looking at their clocks, my GPU has a higher core and memory clock as well. Interesting..

 

It’s probably Razer Blade Pro from MoBo name which is different compared yours, it has new cooling design. Dave2d showed also not bad graphics score on his review unit (I think 2080mq usually 20K out of box). And usually YouTubers run benchmarks on stock and most probably balanced mode without tweaking anything like overclocking or undervolting.

 

Yeah that looks about right. Well I’m not too worried about trying to keep up with a 17 inch laptop, I knew I was giving up some performance for size. I’m pretty happy with my scores and thermals as it is.

 

Is this a stock one? No repasting just an undervolt? If so. . .DAMN. very good temps.

 

RBP 2019 has a more robust cooling solution compared to all previous (and current) models

 

Yes this is stock. It now has 32gb RAM and a 2TB Evo 970 Plus. Still running great with temps never going over 83/84c after hours of playing the Witcher 3 on Ultra settings. I will say that I always keep the laptop propped up to allow better airflow.

 

That's pretty impressive compared to some other laptops I've tested with these hex core processors. I'm glad to see some manufactures are taking cooling more seriously. Hopefully other take note and follow.

 

Its not that simple, the RB15 variants go up to 45watt max. Some six core variants allow the CPU's to pull more power and go up to 80 watts. This causes them to run hotter but also boost higher.

 

Believe me I know. My M15 that I returned ran alot hotter after an undervolt, repaste, and cooling pad. And sure running the cpu at 45w will hurt it in benchmarks. But, in games? Probably not a huge loss. Plus I'd take a cooler running system.

 

Might change in future more heavy titles. But yeah for now it doesnt matter much. Intel needs to fix their stuff though.

 

Oh I totally agree. Maybe AMD will continue to impress and start making more mobile cpu's. Some competition in that sector would make them work a bit harder eh?

 

@DevonRayG Does the Razer Blade 15 Advanced (Mid 2019) OLED version use the 80W or 90W GPU?

 

I don’t see reason why they use 90watt on 240Hz but 80 watt on Oled...wait it’s probably 100 watt and factory cpu undervolting like Blade Pro 2019

 

https://www.3dmark.com/fs/19608214

Says Razer DA720 in the description, which model is this?

 

Yes I saw that, probably Blade Pro 2019, I know one who has it. Do you need anything more specific?

 

The score looks to me that it has a 100W~110W vbios.

 

Yup me too, it has bigger cooling room and new cooling solution I think it can also maintain full rtx 2080, I saw darn good gaming temperature from buddy Blade Pro. Out of box it’s “not normal” 2080maxq performance. I think beats 2070 Area 51m.

 

I guess this is another potential milestone for cross flashing .

 

Haha I knew that
Here’s buddy’s RBP 2019 screenshot

 

@ryzeki @Gr4dy Check this out

 

100 to 110w vbios would be great. I do think this machine can handle a 115w GPU like the full 2070, considering the temps I get with the current 90w vbios.

 

Most likely a pro with 2080mq, I have the same model and hitting the same scores. My GPU was running between 50-60deg C whilst I was testing out BFV and is hitting clocks of 1875 MHz according to my GPU-z logs.

Work has been extremely busy so not had much time to play with it yet, hopefully will have more time this weekend.

 

Can the GS75 handle the 100-110w vbios? Sorry for the delay. Been super busy lately.

 

I'd love to get a 20k score on the GS75

 

I'd say it can handle it. With the current 90W vbios, I am still under 80 celsius and I don't use 100% fans nor liquid metal paste.At 100-110w it should perform on part with the full 1080. Right now we sit slightly below.

I haven't tested without optimus yet though... I suspect optimus is robbing us of a bit of performance so if I have time, I will test it with my TV.

 

The GPU might be fine, but the VRMs maybe are not for that higher load.

 

I bet the GPU hardware itself might be similar to the full

version, it's just capped the power limits that the different max q versions have. Though I would need to check the part numbers to confirm.

 

In some previous MaxQ cases I saw that they often used 1 phase less. Si I dont feel that confident to recommend it with current MaxsQ systems as well.

 

From my experience with desktop vrms, as long as there is sufficient cooling, the vrms can be pushed quite a bit higher. And the ones on the GS75 have a dedicated heatpipe on top of them so I wouldn't worry about it.

 

It is not that simple, it is not just about being pushed (and they are far hotter in laptops by the way, more near the edge).

The power needs to remain clean, this becomes harder when being pushed.

 

Hmm, I'm not too sure about power cleanliness but it hasn't posed a problem to me so far.

In any case, how many phases do you think go to the gpu in the GS75?

I think Blade 15 mid 2019 and early 2019 users should flash the pro card from same gpu model, damn according this 2070maxq Blade Pro 7% faster than 2080maxq gs75, I suppose the past 2080maxq with 80 watt one. I think also the gpu model and rom size would be same avoiding the trouble on installation.

 

If we have a chance to compare the numbers of the VRM held by Blade Pro and GS75 then we'll know what's the difference between the GS75's RTX2080 Max-Q and Blade Pro's RTX2080 Max-Q, and based on the difference to find out why does a VBIOS with that high TDP limit makes sense.

 

I wouldn't call that high, its just nice.

120w would be high

 

Well I mean we need to find out the numbers and compare them to see does the higher TDP limit vbios also comes with more VRM for the Max-Q version.

The reason I said this is because looking back to the last year version RB15's 1070 Max-Q had 5 VRM and GS65's 1070 Max-Q had only 4 VRM.

And the RB15 came with 90W version of the VBIOS, where the GS65 came with 80W version.

What I know about the R22 inductor is that each one's is usually rated rated 32A and the saturated amp is usually 20A.

125C is usually their temperature limit.

 

I looked at the vrms of the gs75 and I think it's a 5(core) +2(memory) .

The mosfets are ON ncp 303150 capable of 50A each
https://www.onsemi.com/PowerSolutions/product.do?id=NCP303150

Assuming a 100w power draw at 0.8v gpu voltage, we'll need 125A



25A per mosfet should produce 3w of heat each. So 15w of heat total.

Seems ok

 

Looks like I've looked at the wrong item,

If the GS75 is using the mosfet you have posted.

then,

The typical amp is 50A each, and the typical over current limit is 80A, which means the GS75 can take up to 80 x 5 = 400A Max, however, the typical amp is 250A.

Indeed looks to be safe.

 

Just received an open box 2080 max-q version from Amazon yesterday evening. After backing up the drive image so I can upgrade the nvme, it turns out that it's not the factory Win10 OS image but instead just a Win10 generic image. That's not necessarily a bad thing for bloat ware, but Razer was already minimal at best.
Besides Synapse, which I can download, to alter the RGB lighting and some background desktop images, what else might I be missing?
Thanks for your help!

 

Check device manager and see if you have any missing devices! If you do I can point you to the driver download page for the new machine and you can download whatever is missing:

http://drivers.razersupport.com//in...w&parentcategoryid=901&pcid=890&nav=0,350,890

But most likely things like Intel RST and and updated video drivers are most likely going to be missing!

Also would you be able to give me a copy of the vbios? I’d be willing to tip you with PayPal or Crypto for your time! We think it’s a special 100W to 115W vbios that should give some performance boosts to normal machines!

If you could get that I’d really appreciate it .

Thanks!! I should have mentioned that nothing was missing in device manager but I will double check, thanks for the link to the drivers download page.

Regarding the vbios, I will definitely help out. Give me a day or so and I will extract it and share. No need for funds, just share any tweaks/info you learn from it with all of us

edit: Oh, I think you are referring to the Pro 17" having a possible higher wattage vbios. I only have the 2019 15"...

 

Finally got everything setup, tweaked Windows 10 install, all drivers updated, etc...
I'm able to tweak cpu undervolting super low, -250mv. So far it is a stable undervolt in all of the games I have tried so far and as well during idle/standby.
Is everyone else getting a full -250mv undervolt on their 9750h or did I get lucky and get a ringer of a cpu?
CPU cache undervolt seems stable in the range of -125mv to -135mv. Will probably just settle on -125mv.

Next thing I want to try is undervolting the gpu.
I've seen some info from Fox and am going to give it a try.
For any of you that have succeeded at undervolting your gpu, any tips or tricks to pass along?

 

You can go to -1000mV on the core voltage offset and it'd still be stable, because the actual undervolt effect would stop lowering at certain point for the Core voltage, the most important thing is the cache voltage offset, as depending on how you set it, it might actually give you a BSOD or freezing.
