The Official MSI GT73VR Owners and Discussions Lounge

I'm confused now....what is your confusion? why don't you get the new MSI GT75VR which has a better more colorful keyboard and a 3ms screen vs the GT73VR which has a 5ms screen?

 

Well I haven't bought it yet. I was about to but curiousty got the better of me. I don't wanna waste anyone's time so that's why I feel like getting one with the cm 238 is the better choice but that's why I'm asking from knowledgeable people like you.

 

How much is it?

 

well, you want my personal opinion right? if the budget allows, I'd get the GT75VR. Period. Better screen, better keyboard, newer chipset, and gold plated heatpipes for more bling factor.

If my budget was tight, I'd get the older one regardless of the chipset. Again, being a slightly older chipset or newer one can never guarantee any better or worse overclocking capability, it's the luck of the draw, silicon lottery...

 

well browse their website dude

It seems only one SKU of the GT73VR has the CM238: GT73VR Titan Pro-425

The other two GT73VR SKU's with a 7820HK have the HM175:
GT73VR Titan Pro-866
GT73VR TITAN PRO-872

The 4k models have the CM236...and a 6820HK...

If you compare the motherboard chipset differences:
https://ark.intel.com/compare/98087,98085

What's the difference between HM175 and CM238 that would affect the function of them to choose one over the other, except maybe Optane support - does the Pro-425 have a short Optane socket as well?

I doubt MSI would put the 7820HK overclockable CPU on a locked motherboard chipset... that would ruin the whole effect

Has anyone posted 7820HK HM175 overclocking problems? Considering 2/3 of the GT73VR models have the HM175 paired with 7820HK's, you'd think we would have heard of problems with that pairing before.

Well I hope the didn't change to the hm175 just to make it exclusive to the gt75vr?! And yes. I also want to because alot of users here mod their cm238 with good results with no throttling issues on the CPU nor random shutdowns after reaching 80watts

 

IDK about that, but I would love to hear about actual problems caused by the HM175 over the CM238 when OC'ing the 7820HK.

Hacking the firmware isn't something I would do or recommend, pushing beyond the limits of the design, MSI puts the limits in there for good reasons.

Unlocking unlimited potential also unlocks component abuse when using power above that designed in originally.

It's not something that's going to improve my use, a couple of FPS more in games isn't worth it.

 

The GT75VR from HIDevolution is in stock and is guaranteed to be CM238 and 7820HK.

If you get the GTX 1070 version, you are IMO, best off getting some IC7 diamond, Phobya Nanogrease or Grizzly Kryonaut for repaste, and HW modding the TDP on the 1070 (gives a substantial performance boost. 170W TDP > 115W TDP, actually putting it ahead of the desktop models, but requires investing in a SPI programmer, 1.8v adapter, Pomona 5250 clip and some male to female zoostlist cables to hook the clip to the 1.8v adapter), but you will need to change the power ID (RW Everything EC RAM) to 330W to avoid excessive battery drain or CPU throttling. The Delta 230W PSU can handle 250W sustained, just keep it cool and ventilated. This is good for 20% improvement over a stock 115W TDP limited 1070 if you overclock it a bit afterwards.

The GTX 1080 has 200W TDP and is fast enough as is. But is also alot more expensive. Don't bother trying to TDP mod that unless you're going for world records or something.

 

Almost none of the laptop models out there coming with unlocked i7 and HM175 chipset. Most part use this cheaper chipset with locked down 7700hq. And yeah, No Optane support for MSIbooks. And HM175 doesn't support Intel Trusted Execution Technology. Maybe the main reason Intel charging less?

You can ask yourself why HM175 isn't a popular chipset for use with unlocked BGA.

 

Help my problem i having the launch csm bios setting is not appearing
With latest bios

 

My *SCM* is working fine with .31B.

 

What I was/am asking was feedback from people with the HM175 + 7820HK as to how they were for OC'ing

The two GT73VR SKU's with a 7820HK have the HM175:
GT73VR Titan Pro-866
GT73VR TITAN PRO-872
https://us.msi.com/Laptop/GT73VR-TITAN-PRO-7th-Gen-GEFORCE<sup>®<sup>-GTX-1080/Specification

 

The following models all have the Intel® Core™ i7-7820HK and HM175, and all are overclockable:
GT73VR 7RF TITAN PRO 4K-858
GT73VR 7RF TITAN PRO-872
GT73VR 7RE TITAN 4K-480 - (The new EVR version)
GT73VR 7RF TITAN PRO-866
GT73VR TITAN 4K-867
GT73VR 7RE TITAN-427 - (The new EVR version)

 

Thank you Donald, for posting even more models with that pairing of HM175+7820HK... wow.

What models have the CM238 + 7820HK other than the Pro-425?

 

You are most welcome...but my name is Donald

 

Fixed

 

I want some of what MSI was smoking when someone decided to butcher their product line like this...

 

probably some amnesia lol
my one is cm238 7re-287

 

MSI Gaming GT73VR 7RE(Titan)-287UK ?

 

Whoops...I forgot to answer this part.

None of the current MSI GT73VR models in the US market have the CM238. When they introduced the GT75VR, they brought out the new 'EVR' version of the GT73VR (although you won't always see them referred to as EVR). All of the models I listed are the current models in the US market, other than the MSI GT73VR 7RF TITAN PRO-865 that has the Intel® Core™ i7-7700HQ with the HM175.

Their idea of course was to introduce the new GT75VR as the flagship, and dropping some of the features of the GT73VR so that the new flagship could shine brightly.

Trying to ponder how the brain cells operate in any corporate ivory tower is usually a frustrating effort.

 

Hmm, actually, I would prefer something better to smoke that whatever they were smoking

 

You think the computer industry is bad, try working in the car business. I love it to death, but you'll scratch your head raw trying to comprehend what those MBAs do on a daily basis.

 

Ah yes, with their HP 12c calculator in their shirt pocket. They are brainwashed to believe the numbers are everything, but simply cannot understand that bringing quality product to market will make the revenue numbers sing. They seem too focused on costs as opposed to revenue.

It just goes to show what they teach in them there highfalutin 'versities.

 

Hi everyone,

MY BIOS is E17A1lMS.319
is it ok to update my laptop to new one E17A1lMS.319 ?

anyone updated yet?
and instruction is appreciated to helpme how to update

thank you

 

.31B is the newest one. .319 is the older one. Just put the file on the USB flash drive and run UEFI update.

You can update, but after flash and power off, if it doesn't start 'boot looping' after 5 "forced" power off (power button 5 seconds) and power ons, you need to clear CMOS to force it to full reset.

 

I've been reading this thread over many pages, searching the thread for the chipset terms, and still can't find a firm explanation as to what exactly the HM175 limits? Something about max voltage use?

What is the rough % loss from this? Does it affect casual overclockers (Intel XTU) or just cutting edge settings?

This is the only site on the internet mentioning issues with the GT73VR and chipset, I can't google any other source mentioning issues (or anywhere on reddit)

 

cutting edge settings. I don't know about the HM175 chipset versions using 17A1EMS1.108 EC version, but .112 EC will shut off the laptop at 80W of CPU power draw.
Now this might just be a simple EC Nerf and changing offset F4 from 8C to 0C might fix that, but there are other throttling shenanigans in that EC, like having the CPU be forced to 800mhz if you set PSYS_PMAX to 2700 (337.5W), and put ANY load on the GPU at all, yet that doesn't happen with PSYS_PMAX=2400. And none of that happens on the CM238 version.

 

Thanks, I feel a better going with this as my #1 pick. For me, setting an easy mode overclock should be more than sufficient for my needs, especially with the firepower this has

 

There aren't any issues with either motherboard chipset, except for @Falkentyne 's hacks to the CM238 BIOS to unlock Power limits, which I don't recommend anyone duplicating.

Either chipset will allow overclocking the 7820HK

 

Put up a new thread here with a poll<Where people can put up their max oc'd cpu clocks +results and what mobile chipset (Kaby lake) used>. I'm sure yoo can.

 

Reports from owners here in the GT73VR Owners thread is good enough for now. I don't see a wave of people responding either.

Most people won't even think to look, and don't know either way, what motherboard chipset they have.

Especially if there are no differences in OC'ing. If there are then we might see posts here asking questions.

 

Hi everyone,

I recently noticed that MSI released some GT73"E"VR and I would like to know what's new with thoses lappys. I can' t see any differences with the regular GT73VR exept the price is lower.

 

thank you for the reply,
How can I vlear the CMOS ?
sorry I didnt do that yet! is it safe to clear CMOS?
if yes, how?

thank you

 

I've cleared cmos over 30 times. It's 100% perfectly safe but very annoying. It's required to clear CMOS when the laptop won't boot anymore because of changing things like RAM timings to the wrong thing, or sometimes if you get the "MUX" switch black screen problem and don't know how to switch to the iGPU to reverse the bug and undo it. I mentioned in previous posts how to change to iGPU blind, in windows, if you have the dgpu black screen bug.

The GT73VR has two Bios chips. Doing a full CMOS clear I believe wipes the first Bios chip and copies the backup Bios onto the primary Bios, which is why it boot loops like 5 times.
I believe there are two ways to clear cmos:

Short way: press power button to power on but don't release it, keep it held down until it powers off by itself, then release it, wait 5 seconds then power on again. At least two people have said that this was good enough to reset bios data when they had black screen bug from switching dgpu->igpu->dgpu. I think this does not reset time/date.

Long way: Clears CMOS fully, copies backup bios onto main bios:
Power off, hold down power button for 45 seconds (with power light off), power on, wait 60 seconds for power light automatic cycle, then wait for boot loops. This requires waiting at least 2 minutes. This also resets time/date to 1/1/2000(?)

Sometimes if the power LED cycles once (after 60 seconds) and you wait 1 more minute and it still freezes and doesn't boot loop, you have to do the 45 second press again. This will always work.
I had to do *two* 45 second presses after flashing Bios to .31B because it didn't even power cycle after flashing was finished. Works great after though.

 

Said earlier in thread from a reseller rep that the "EVR" is the rebranded GT73VR update post-GT75VR release (they shifted some high-end settings to the new flagship model).

As with my question, seems they changed the chipset but it shouldn't be noticeable for most users.

 

Thank you

 

Anyone still using that nahimic software ? It keeps crashing for me with cloud 2 headset. I wanted to try out that "game mode" where it lowers the bass and bumps up the treble and rest of the shizzle,but it keeps crashing.

 

My speaker is generating click sound when i open folder and sometimes by itsel!!
i google it and noticed that MSI suggest to update realtek+Nahimic!! i did but didnt solved!!
any solution is appreciated.

 

Are you using the latest version?
[ Download]

 

Have you also updated BIOS & EC firmware besides driver update?

 

Yes i am using the last driver, always keeping update the drivers.
about BIOS I updated to previous week(the last one) and my EC framework is the last one which was uploaded in Q1 2017.

it really really anoying!

I thought it is the Theme sound like windows XP (when you opened a folder it generated klik sound)

I changed my theme but still persist!

should I clear my CMOS!?

 

Ok so hybrid power (battery leech) on the 230W unit can be "disabled" by using the 330W power ID (you can go past 230W without the battery being touched at all), but I can't find a way to disable hybrid power on the 330W ID. It seems that when you exceed 250W power draw, the battery starts being drained slowly. Maybe there's a way to prevent this with the EC RAM, but I can't figure it out. Maybe that strange "10" at EC RAM offset E4 has something to do with it, but I'm not going to bother. If one of you guys feel like it, be my guest.

I can tell you RIGHT NOW that the Gt73VR is FULLY CAPABLE of drawing 330W without touching the battery with the 330W power ID, without any throttling. I was just now able to pull *310W* system power with a GTX 1070, yes, 310W, by modding the 1070 TDP to 185W, enabling AVX instructions and running 4 thread prime95 and Valley at the same time. Kill-A-Watt reported 350W from the wall. CPU pulling 95W maximum, 1070 pulling 185W, rest of system estimated at around 30W. So the system was using about 310W, battery disconnected, no throttling, with a GTX 1070. To do this without battery drain requires DISCONNECTING the battery and then using RW everything to write "09" to register 31 (this turns "on" the battery charge circuit) and "64" to register 42 (this writes 100% battery charge to the battery level). This tricks the EC into thinking the battery is connected (even though it's DISCONNECTED) and removes the CPU power limit 2 (PL2) throttling limit from the battery being disconnected (both values must be written for this to work). This power limit (with the battery disconnected) seems to turn on at about 170W-200W (somewhere around here). I don't know if the same thing happens with GTX 1080 users. But it's not the videocard being throttled--it's the CPU.

Changing the two registers (31 and 42) allow you to draw the full 230W with the battery disconnected without CPU throttling, with power ID 10 or 90 in register E3 (PL2 gets turned on after 230W), or the full 330W with the 330W ID (power ID 11 or 91 in register E3).

So clearly the system is CAPABLE of drawing the absolute maximum 330W without the battery being needed whatsoever, but I can't figure out how to do it without disconnecting the battery and hacking those 3 registers...

Anyone here want to find out what register E4 does?? The one that always has a "10" in it? It's right next to the power ID register (this register is used in other models too, like the barebones 16L1 and the GT72VR) so it must control something....

 

Yeah,was using the newest one,its crashing all the time.I think it has a conflict with cloud 2 microphone,because every time i switch to microphone tab it crashes instantly.

 

Anyone here have the 1070 SLI version of the **kaby lake** GT73VR (7RE) +7820HK?
(the 2x230W version). Not the skylake version. SLI version only.

If you can can you please download RW Everything and go to the EC page and post a screenshot of the EC RAM page? Make sure you're on AC power and (if possible), the battery is between 91-100% and "not charging.". Thank you.

 

Does it produce any error code when it crashes?

 

@Falkentyne can you create modiffied bios with -100 core voltage offset in bios setting??

 

SVET does such modified / custom BIOS's, post there or PM him with your request(s):

MSI Global English Forum > MSI GAMING > GAMING Notebooks > Private Custom Modified BIOS'ses & EC-FW
https://forum-en.msi.com/index.php?board=51.0

For the undervolt you'd set it manually in the custom BIOS / BIOS configurator, a unique setting you arrived at for your particular CPU / laptop.

There is such a wide range of stable undervolt from CPU to CPU, some only as good as -15mV all the way up to (down to?) -220mV, you wouldn't want a preset BIOS setting of -100mV unless you already verified that was the optimal setting.

With a fixed -100mV undervolt BIOS, there would be a percentage of CPU's / laptop's that would crash, and many that could do much better - they'd be leaving undervolt "on the table" losing out on more heat reduction.

It's better to get a custom BIOS where you can vary all the settings rather than a set of fixed settings.

 

You can do it yourself. Follow @sirgeorge 's instructions in his earlier posts. The most important thing to remember is NOT to edit the downloaded Bios file from the MSI website--the only reason he mentioned for you downloading THAT File, is to find the proper GUID for the "Bios lock" feature, which you need to disable with EFI boot, then after that, you dump the "ATPIO capsule" (user space) with AFUGUI64 or whatever it's called (I forgot), then set the bios options to user or supervisor, and then you flash that with FPT64.

I highly suggest you buy a Skypro SPI programmer before attempting this, so if you brick something, you can easily recover. And unlike the Video Bios chip, I don't think you need the 1.8v adapter as these I believe are 3.3v chips (but its a good thing to have anyway); all you would need is the SPI programmer, the male to female jumper cables (like the zoostliss cable set), and the Pomona 5250 SOIC8 clip.

But I'm getting way off topic.
Svet can mod it for you for a donation ($20'ish). But keep in mind you will have to donate again if you update to a newer bios revision. If you know how to unlock your own bios, you can do it anytime.

(Sirgeorge unlocked his own bios himself).

 

It seems quite difficult. I will try to understand it first. Thank you for your help
