i don't think CAMM modules will stick, valiant attempt but futile. didn't like the new top screeched screen with 16x10 ratio in the 7670, it looks and feel odd to me. with the new cpu's with 30% more cores... ooh boy that would be interesting to see how they will pull this one off.

unintentionally that's what happened, i didn't plan on going through six units, first 3 7670's were all overheating eventually I gave up even with Dell kindly replacing the unit 3 times with zero issues, after a while i decided to give the 7770 a try, the first 7770 unit had an odd issue with dGpu, it would start lagging out of the blue for no apparent reason, they replaced it a day after it arrived with the second (fifth unit) the fifth unit had an issue out of the box where screen randomly flickered in patches in various stages even boot, that was also reported to customer service and immediately replaced with the sixth unit, by the fifth while waiting for the sixth unit I already made up my mind, I had no plans on keeping the last replacement knowing what's expected, the sixth was more of a customer service procedure I was not even going to open the box, just send it back and be done with it, as luck would have it I did open it and was pleasantly surprised,

i run through 6 x 12950HX and can confirm the silicon lottery is a thing with these new cpu's, i had my mind made up by the fifth 7770 unit that i will not be keeping the platform, when the sixth unit arrived it behaved completely different then any previous unit I had before, it didn't run crazy hot out of the box, it was still idling high in default config but it is relatively low at 70c, further testing the cpu it is able to withstand a significant undervolt and remain very stable unlike any cpu before, as hard as it is to believe i am idling below 30c doing simple daily tasks, that was not achievable with any of the 5 units i tested before, despite my efforts i was not able to idle at acceptable temps, with some units i was able to get to around 36-40c idle, as soon as i added my 3 M.2 drives temps shoot to 50c at idle, my current system is populated with all 4 M.2 slots and still maintains below 30c idle throughout the day, for this sixth unit so far I didn't touch Dell's paste yet, all other systems I had no choice but to try and replace Dell's paste and later on liquid metal application for both CPU and dGpu to try and get some stability (i tried with just CPU and both CPU and dGpu LM TIM), from what i can see now with my sixth system experience all my previous attempts were no more than a Band-Aid remedy for a broken leg, i cant explain the variances only report my first hand experience and impressions from the past few months with 6 units with 3080Ti and 12950HX,

not a guarantee it works! (especially being new) you cant trust it until you can 😉 I'm sure you confirmed the usb drive is accessible and fully booting on other system, i would try to confirm the m.2 drive with another system at this point before you start pulling hair,

are you able to rule out basic functionality by running and formatting the drive on another system? is it possible the that drive is encrypted or maybe was part of a raid array before?

Samsung Magician might be able to diagnose the drive (it should work with none Samsung drives as well) https://semiconductor.samsung.com/consumer-storage/magician/

you also need the presets to set each parameter value to +/- first (its somewhere in there too), still need... parameter to set clocks, iccmax values, and cache ratio, PL1/2/4 are exposed and can be configured manually, no issues what so ever here setting up win11 on 7770, also on AHCI and added +3 Samsung M.2, no driver was required during setup, you may encounter some security related issues etc. if you activated them in bios or trying to prevent usb access etc., these option are there if one wanted to activate them, make sure you didn't activate an option/feature that's doing what its intended, i don't think intel rapid storage driver will be needed at that low level, most likely the drive manufacturer should have the right driver for you to download if its not an OEM part, don't assume the drive works as intended because its new, new drives can be defected too!

i have tried without much success, also note that not all options and their values are exposed for editing,

i didn't use my secret sauce when running benches on the 7770 (i did it with the 7670) the 7770 was benched right on my desk with 74c ambient temps and a 240w brick, i only applied undervolt setting which i posted few pages back, my current 7770 is also running with stock paste atm, the rest is just win11 service and application tuning, as it is 3DMARK score is now 13500 with unlocked dGpu, I'm pretty sure from here I can easily squeeze additional 5%-10% with LM TIM, 330w brick, and little secret sauce,

i believe the diagnostics test is over a white background, that will make it hard to spot white flickering that's why i suggested to find a low res mode like safe mode where its black and little to no drivers involved until late in the load, the goal is to spot it outside of windows to rule out any driver involvement, in my case out of the box on first boot It was noticeable, it wasn't bad or persistent but occasionally small random small rectangular sections flickered quickly no matter if I was in windows or booting or in safe mode, that was a replacement for the first 7770 unit which got immediately replaced to the unit i have now, 3 rounds of 7770 replacements before finally I got a unit that was behaving "relatively" nice without displaying any major issues out of the box (for the record all 7770 units arrived with bios 1.6.3),

was the flickering white patches in random areas of the screen? try to logon to ms-dos or a low level screen color stage like repair (hod shift when you click restart) and boot to safe mode option 6, reason for the above is to try and observe these flickering happen outside windows as low color level will induce these, during boot time it is also possible to observe these flickers, if you are able to observe them outside the game or windows it is likely not a driver issue but a hardware one, I had similar issue with one of my recent exchange units.

paste this little script in a batch file to easily cycle "NVIDIA Platform Controllers and Framework" ON/OFF mode con: cols=40 lines=4 @echo off powershell -Command Get-PnpDevice "ACPI\NVDA0820\NPCF" | findstr /i "error" >nul && (powershell -Command pnputil /enable-device "ACPI\NVDA0820\NPCF" & echo ** NPCF Enabled **) if %errorlevel% equ 1 (powershell -Command pnputil /disable-device "ACPI\NVDA0820\NPCF" & echo -= NPCF Disabled =-) TIMEOUT 3 > nul :: in case of DeviceId error or to use with a diffrent device, query for DeviceId with example below :: Get-PnpDevice -FriendlyName "*Friendly Name Goes Here*" | ft -Wrap -AutoSize Instanceid

oops... was on the wrong tab (might be barking at the wrong tree here, 115 is just default )

my gpu-z advance tab is showing a bunch of weird stats (prob because i am on hybrid mode) but it also exposes a reg path with corresponding files in "C:\Windows\INF" only oem1.inf and oem35.inf are NVidia's, Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000

a longshot but viable... it is possible that wherever CPU-Z is reading its 115w limit value, Nvidia PCF is also reading that value for threshold instead of the 150 value set in NVidia system info, (despite my efforts i was unable to trace that illusive 115.0 W TDP (TGP) value source)

what sort of artifact did you see? (in a way you want to see artifacts to find your threshold to back off from) few frames flickering is not a big deal i have seen that happen when i push memory clock speeds too far, +1400Mhz is the upper limit here before i start to see some artifacts with higher memory clocks, maybe the artifacts coming from the +138% power limit increase side? here i can only push to plus +130% max as the slider stops after, for the record, power supply during bench is pegged at 240w for the entire duration of the bench, sometime it spiked slightly over 240w which tells me the 330w brick is now needed to exceed these limits safely and remain stable (running with 100% stock Dell paste still), a small tidbit i noticed MSI native OC feature (top left corner) works fully when NPCF is disabled, below is my best score thus far (i feel no need to further prove my machine), needless to say this is staying for good here with me https://www.3dmark.com/spy/34146281

setting above reg key "start" value to 4 achieves the same result without disabling in device manager (seem to be some NVidia telemetry service), Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvpcf] "Start"=dword:00000004 to make sure it stays off one can also edit "C:\Windows\INF\oem27.inf" line 49 "StartType = 3" to "StartType = 4"

is that a dell or nvidia driver implementation? i plan to try and track the driver itself, maybe there's an inf instruction or something we can edit ourselves, Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvpcf

@win32asmguy confirmed wizard man! \ o / https://www.3dmark.com/spy/34142631 https://www.3dmark.com/3dm/86172546

@win32asmguy i think you can squeeze at least 20% more for cpu score, your dgpu score is as good as i ever seen on the 7670, are you able to replicate dgpu 125w usage? HWiNFo will occasionally display odd value calculations (see below supposedly my dGpu has 750w power limit )

haven't experienced crashes here yet even with latest 1.8.0, system is on 24/7, (classic power plan active with S3 enabled via setup_var), any hints from log viewer? which apps were running in the background maybe one of them needs an update? if not disabled you maybe able to find clues in bsod memory dumps,

a simple device like this goes a long way https://www.amazon.com/dp/B09KXB7QF3

Thank you, but common... these are only 41 out of tens of thousands bench results hand picked off the same site i directly compare with, just reposted on their site! their selection also doesn't represent same hardware average but a wide array of different combination and chassis sizes etc., the conclusions you seem to draw are fundamentally incorrect in my view, ill start with Mr. @Dell-Mano_G with all due respects! i never read his posts or visited this site prior to owning the 7X70's, anything he may have said with regards to power limits had no grounds in my decision making or in anyway explains the discrepancy we see atm with declared 150w limit and actual 115w limit, kudos to you for being able to draw the right conclusion and make the right decision to opt out the 7X70 platform beforehand, your opinion about my score is your opinion i have no issues with how you perceive my $4500 investment. now if you actually studied these scores closely you will also find much higher than 115w sku's with lower score than the 7770 unit gets, that doesn't comfort me or save me the time i expect and paid for, what customers expect in return for their investments is very important to manufactures despite your plight; how we feel about the product should be No.1 concern for any manufacturer planning to stay in business, this is not the army sir. 😊

if you scroll back few pages you will find detailed posts about these test runs,

@IamTechknow we see 115w + 5w boost max yes it has been verified by at least two separate tests i conducted, first test was with a Dell 330w power supply with PL4 removed (set to 0 or 330), second test CPU PL1 and PL2 both limited to 30W leaving additional 80w headroom for the dGpu to use but it refused to utilize 80w available and remain at max 115 while entire system consuming 160w total during bench,
