Hey guys I got my GT73VR last saturday.
I OC'ed it to 4GhZ and 3.8Ghz with a 40-50mv negative offset in XTU
But my main concern now is that I dont like using software to OC.
I want to set the settings in bios to have them perma 24/7
My temps dont go above 66-67c when gaming on a cpu intensive game.
When I set the multiplier to anything it resets after the first reboot even tho the laptop is stable an di restart the correct way.
If I set in XTU and restart correctly the OC sticks but I want to do it on a hwardware level.
Also I cant set the voltage offset to a negative value in BIOS and I dont see even alot of options in the bios to change
Is the BIOS on GT73VR limited in anyway
Something not right there, that's slower than a Haswell dual core and even slower than a quad Haswell running at lower clock both of which run under 8 seconds.
You cannot afaik, contact svet if he will take payment for modded GT73VR bios.
XTU adjust hardware level multiplier/voltage, so you shouldn't have any problem. You're only doing the adjustment trough the OS (XTU interfaces with BIOS)
What do you both expect from a BGA cpu paired with under-spec 2400MHz RAM?
Doesn't have to be on par with
@Papusan but less than 8 seconds.
4 generations later and an unlocked 6th generation mobile CPU cant beat a second generation unlocked mobile CPU in SuperPi. Very sad.
@Nikaidoboss for many years since EFI came about it has been possible to change hidden BIOS settings without having to flash a specially modified BIOS and risk bricking or loss of warranty. Don't know why it never took off TBH. There's a free util called IFR extractor or something then just a case of using UEFI shell to change the variables.
So..at ~4GHZ, the 6820HK can take more than 75 watts? That's sounds a bit high even with Prime95. But i'm totally guessing, haven't used a Skylake gaming laptop yet. But the internal GPU being off, CPU is quite efficient. GPU is a part of the TDP rating on the spec sheet.
I am considering getting a MSI GT73VR. Overclocking 6820HK on that? 4.2GHZ 100% load all cores Prime95 stable? 4.4GHZ? Or is it artificially (?) limited (on the MSI) as it is with the Asus?. I suppose it uses a different socket than desktop Skylake, can't plop it in a desktop gaming mobo, see what it can really do. Thanks.
MSI is known for locking their CPUs to their default TDPs in their laptops. I don't even know for certain if their top end ones get around this, but I know many of their pascal laptops do not. Don't expect much.
The ASUS limits the laptop to 75W. It does not matter the speed; it matters the load. You could probably make the 6820HK pull 75W at 3.4GHz under Linpack. On the other hand, a game (especially 60fps) is unlikely to make it pull 75W at 4GHz. Also, please note, Mobius has *THE* lowest-voltage-using 6820HK I have ever witnessed. He is essentially returning a "golden chip" as far as laptops are concerned. Another user on this forum was not able to get under 1.25v on his chip at the same 4.1GHz, and I've seen many other users who sit cleanly above 1.3v the minute they crack 4GHz. They might be rather incompetent in their voltage adjustments; however it's known that higher voltage (and thus higher power draw allowance) is generally required for the mobile chips when overclocking.
The GS73VR is still a thin laptop as far as things are concerned. And its paired GPU is the nuclear reactor that is Pascal. You will not be overclocking the CPU that high and keeping it stable, especially if gaming is your desire, even if you had unlocked power draw capabilities for the CPU (which I *HIGHLY* doubt). It would not be kept cool.
It uses no socket. All mobile CPUs are soldered-only, and have been for the last two years, and show no signs of changing from this in the near future. Nobody with clout in the industry is making any stinks about it, nor about how slow the Skylake mobile chips are, so it's not likely changes will happen anytime soon.
Well at least with MSi you have the opportunity to pay svet a small amount of money to unlock the power adjustment thing. With ASUS there is no chance.
Johnksss messed with 303 and 304 bios, it worked on his G752VS but didn't work on mine (unlocked setting in the bios is a dud).
Funny enough, that "golden" 6820HK is probably in line with the very bottom tier 6700K or 6700-nonK chips.
I was able to run 4.1 with little to no throttling (-9.8mV, adaptive mode) on OCCT for 6 hours straight. OCCT is afaik, on par or even worse than Linpack. CPU is on the borderline of 75w during the mentioned stress test.
Maybe the 4+ GHz chip that need more than 1.2v
didn't have the voltages set to default in throttlestop first. I know that ASUS "TURBO GEAR" OC utility set the CPU to 4GHz @1.4v (really high!).
So it's just a case of manufacturer OC app / preset level getting a little too crazy on the voltage adjustment.
In my case with the 6820HK, I didn't really bother under volting it when over clocking it due to my overall temps being extremely low. As you know, my focus was mainly on how cool I can get the laptop to run with Grizzly Conductonaut and repadding it with FujiPloy 17.0w/mk. Yea, my chip was a gas hog reaching 1.339v LOL, however my CPU and GPU Temps were outstanding as you saw from my bench tests using OCCT.
Of course it'd be nice to be under-volted to the lowest we can possibly get it, but in my scenario, under-volting was the least of my worries due to my temps being excellent.
Max CPU Temps w/ OCCT: Mid to High 60C's
Max GPU Temps w/ Firestrike, Unigine Heaven, Gaming etc...: Mid 60C's
Ah. I was considering Svet's unlocked BIOS too though. Some of their models? The sliders just kind of do nothing.
interesting.
Yes, it is.
OCCT, I don't know. Does it use AVX? Because I pull 86W in Linpack on my chip at 3.5GHz. Not sure how Skylake manages 4.1GHz at 75W unless AVX is abusing my haswell chip in Linpack. I've never used OCCT.
This is possible for ASUS, however I was considering *all* 6820HK chips I've ever seen. This means in Alienware and Clevos and MSIs as well. ASUS' software crap doesn't give them any issues.
If I stop being lazy I'll install OCCT and run a stress test to see how high the power draw goes. This is a big "IF".
Edit: Stopped being Lazy. OCCT pulls give or take 70W. Power draw went up slightly with temps as I know can happen; went from about 68W to 71W. I didn't keep it running though; it's going to overheat me. But it doesn't draw nearly as much power as Linpack. I used the "large data" setting; not sure if I should have used small or whatnot.
Using Linpack (All available cores, AVX capable, 50% memory) result in 190-198w. Same as the Large data.
But to be fair, you're rarely ever going to push the CPU this hard. OCCT large data set for 7+ hours I what I recommend for stability check. Something like Linpack/Small data set doesn't get used by real life programs at all.
Problems? See this thread at archive.org.
