@Lost_N_BIOS Thank you so much man! It worked flawlessly i really appreciate your help! Now to get into some tweaking 😉 I'll just go through this thread and see what options have worked for other users. Thank you once more you have my complete gratitude! ❤

@moonzz - You're welcome and thanks for the quick test and report back! Happy tweaking

Hey, sorry to bother again i just wanted some help with ram OCing.
It seems i can tighten and change the timings but whenever i try to change the frequency the laptop POSTs but will give a black screen and eventually reset the ram config to default. I'm wondering if theres another setting i need to enable to OC ram or maybe my ram isnt compatible since I'm using the stock Samsung ram. If its just my ram it's alright i'll look into upgrading it.
Thanks again

Then probably timings are too tight for what speed you are trying to run, or not enough voltages (ram, VccIO, VccSA)
That, or your ram wont run the speed you are trying. Stock ram can probably OC, but maybe not super high. What is the stock speed and timings? What speed and timings are you trying to run? How much memory total is this?
Show me SPD tab of CPU-z, with one of the memory sticks selected.

Ah that makes sense. Where would i increase the VccIO or VccSA voltages and if i do what do you recommend I increase them by.
I've experimented increasing the frequency to 2800 for starters but even then it wouldnt work.
I'm using 8GB in dual rank 2666mhz, i was thinking maybe i can try to get it to 2933 or maybe even 3000 and whatever timings would work, i'd adjust them to see the best i can do.

any chance i could get a copy of the modded bios for this laptop? i have the 9750h and 2060 version of the laptop and want to set my upgraded memory to 3200mhz like its rated for.

@moonzz - Advanced >> OverClocking Performance Menu >> Processor >> Platform Voltage Overrides
See page 37, and or some previous pages, other users discuss what worked for them. If 20/21-22-22-48 (or maybe 21-21-21-48 ) + stock voltages don't let 2800 work for you, then that memory just may not be able to do 2800, or you need to try 3000/3200 instead
Or, as mentioned on page #37, some of the other subtimings may be too tight, you'll have to loosen first too

@lowrck - Please give me your exact full model name and a link to your BIOS download page.

First disable secure boot, TPM/Encryption if enabled, remove any BIOS password, then dump your vars and send to me per below
download the following package, and run the command below from each versions folder that directly contains it's exe. Before doing this, make sure you have secure boot disabled in BIOS, any BIOS password removed, and TPM/Encryption disabled.
Once done, copy the entire folder somewhere, delete everything but any created vars.txt and then repackage this and send to me, this way all created vars.txt remain in place in the folders of the version that created them.
http://s000.tinyupload.com/index.php?fil...212104496994806

H2OUVE.exe -gv vars.txt

Then do step #1 of this spoiler only, and send me the file. Then delete it, we will make new #1 file after I send you back modified vars, then you will be able to do step #1-2 after you flash back in mod vars

EDIT: sorry forgot to tag you so this would show up in your mentions. @Lost_N_BIOS
ph315-52-72EV is the model number, https://www.acer.com/ac/en/US/content/su...002920061DB2600 is the download page for it from acer. im running 1.08 because of bugs in newer versions. don't know if that matters though.

vars link: https://gofile.io/d/td1j6a
bios link: https://gofile.io/d/YeJEVw
me version is: 12.0, Build 1416, Hot Fix 31

note:
tinyupload is currently down at time of writing. so i used a similar service from gofile. sorry for any inconvience, but i figured you would rather have something rather than nothing while i waited.
---------------------------------------

@Lost_N_BIOS i forgot to ask. i have flashed an asus 90 watt vbios to the graphics card. it uses, from what i can tell, an independent eeprom from the system bios so i don't think it will effect it but i can flash back the stock vbios if that is required but i'd prefer to not potentially cause complications by reflashing over the "upgraded" vbios.

@lowrck - BIOS version only matters if I'm grabbing pre-edited modules that I have done for other versions, most do not use older BIOS like that so I will just redo edits on your exact BIOS.
How did you flash the vBIOS? If via NVFlash or ATIFlash, then what you flashed in will remain. Also, really, even if vBIOS was inside BIOS, it would remain untouched and as-is during reflash, because I will be editing your dumped BIOS and will only touch one file (Setup)

Yes, tinyupload has been VERY slow to load past day or so, and of course, not GoFile.io not loading out for me either. Upload to uploadfiles.io instead, thanks
GoFile finally loaded for me, around about same time it took tinyupload to finally load out too, maybe 2 minutes for each. Next time, please zip BIOS, thanks

Here is unlocked vars, put this into 100.00.16.08 version folder, then flash back using following command >> H2OUVE.exe -sv varsM.txt
https://ufile.io/jfv2me4t

There will be list of success/fail, reboot and then redo FPT spoiler step #1-2 and confirm #2 goes without error, then upload the new #1 file for me.
Use new name for step #1-2, if you did not already delete original biosreg.bin, or delete it now

@Lost_N_BIOS yes i just used nvflash for the graphics chipset.

here is the file generated by fptw.exe:
https://ufile.io/vtgbzb98

it completed successfully and said that the existing data and new data were identical. so i'm guessing your var mod succeeded. sorry about the host, they were just one of the first i found when searching for small file upload, and sorry for the non zipped bios. i couldn't remember if i was supposed to zip the bin or not. i have this time. thanks for doing this, its awesome to have the ability to xmp my ram.

@lowrck - Since you used NVFlash yes, that means vBIOS is on it's own chip and not inside BIOS
Yes, if no error on #2, then unlocked now / all good and you can now flash in mod BIOS
Thanks for zip And you're welcome!!!

Here is your unlocked BIOS, flash it back via >> FPTw.exe -bios -f biosmodm.bin
https://ufile.io/ngpt7d3n

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user lowrck at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not lowrck, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

to help user out my cheap 2666 ddr4 kit if fully stable with 1.25V @ 3473 mhz (21-22-20-48) CR1 to be more stable and reach max speed up the uncore 100 is too low i wil recommend uncore + 118-125mv and put it in CR2 if cant pass these speed ...

Put 13265 in REFI (or try to max it out 65635) to ease the overclocking and 674 the other parameter (forgot the name 470 before)

And if you undervolt too much on the cpu cache (me -175m vs 170mv for me max) DDR4 will be unstable too do ALL of you tests first with -125mv on both VID and cache before undervolting them !

@Lost_N_BIOS @saltinbank Thanks for the helpful advice but I'm afraid its a bust. I've tried all frequencies above 2666 at stock or with increased voltages and higher timings but it seems like it just wouldn't work. It might be possible that it's my ram or is there something in memory settings that's preventing it from clocking higher? I tried clocking to 2400 and works just fine so i guess I'm out of ideas

@moonzz - Could just be poor performing default memory, not all will OC the same. You'll have to pick up some new better memory, then you should have much better luck.
Or, you can run 2400-2666 with tighter timings. Be careful and work your way down slow, too tight and you might get stuck unbootable with no way to recover

@Lost_N_BIOS Yeah i suppose it could be bad luck with the ram. Thanks for all the help anyway i really appreciate it :)
In any case if i do set a bad ram timing it auto resets to default so i guess I'm good in that sense. Got a good Cl 15-15-15-39 timing at 2666 so I'm set :D
