G7 7500 RTX 2070 Drops Framerate

I give up lol now its underclocking the cpu to 1ghz. I forced it to stay at 4.2 but it pegged 100c and got horrid results. This computer is just really bad, minus the monitor. I'm taking it back before it blows up.

So I narrowed it down, it is a heat problem. After I ran a game called gal civs or ran passmark the cpu would underclock it self to 1ghz to 3, till restart. So if u overheat the cpu it apparently has a feature that won't allow it to go back to original clocks till restart. Usually if I ran passmark 1s it would do this. I stuck it on top of a big fan and it ran 5 times in a row. 

Now I'm 100 percent sure it is a heat problem i stuck it on a huge server rack fan and it gets 100 fps in heaven, so at this point I dont see any reason this computer is of use, you have to keep a huge fan on it at all times to play any cpu intensive game, or its going to underclock it self to 1ghz to 3ghz, which makes it slower than a amd bull dozer cpu from 10 years ago. 

same here and its in the frist 3 mins of playing warzone gets to 92c

Yep it is 100 percent the dell computer, they never tested any of it, and it doesn't work right. I took it back and got a different one by razer with the identical specs 10750h, 2070 max q, 3000 mhz ram , and same 4k oled. I have ran passmark over and over it keeps the same score. I also ran cinebench over and over 20 times gets the same consistent score 1100. Also ran galactic civs 3 for 2 hours it stayed consistently between 3.8 and 4.5. The temps never got over 80 playing civs and 75 doing the bench marks, vs 100c on the dell. The dell on the other hand gets a higher score for the first run, 13800 2900 single, vs the razer at 12200 2800 single. The dell also gets 1300 on cinebench the first run. After that tho the dell underclocks it self to 1ghz and gets 600 cinebench, and 6000 1000. In gal civs 3 it starts skipping and turns take really long. So sadly dell dropped the ball on this laptop, and didn't test it to make the cpu and gpu work together within the limits of the physical computer. They made it so on a simple quick test say in the store you would think you found gold, but after long use it would fail. Since there is no way to undervolt the cpu, and control its speed, it will never work right unless you have a server rack fan. Or dell modifies the bios and makes it so it is in the limits of the bad cooling system they put in. 

If you are the brave type, you could replace the fans with better ones, and use liquid metal and you would be good. I have delided many of desktop cpus, but I wouldn't want to mess with a laptop my self, its too compact and one mistake might destroy the entire computer, minus just one chip in a desktop.

Hi guys! I think we have a solution!

I have this issue too and it’s been driving me nuts trying to get to the bottom of it. What a rollercoaster thinking you’ve solved it and then the dreaded FPS drop comes back with a vengeance.

As it turns out, Dell for whatever reason have the RTX2070 clocked and locked at 1900mhz in their bios, so the GPU is drawing huge voltage and shutting down with over voltage protection, regardless of temperatures. This would explain why you can press the G button and it will kickstart the card again (for a few minutes). My Logitech keyboard confirmed this on its LCD screen in-game, showing clock speeds of up to 1900mhz which is insane for a card only rated to 1500ish on boost!!!

Fortunately a few whizzes over at this deals website have been able to suss out the problem and implement a solution involving reflashing the bios to allow undervolting of the GPU, then using MSI Afterburner to undervolt it (thereby indirectly limiting the amount of clock speed the GPU can achieve). Check it out:

Hope that helps!

No idea why Dell had it overclocked by so much from factory, or why they haven’t looked into this and developed a bios update to fix the issue. Disappointing as the rest of the laptop is quite brilliant, but with this issue, definitely not fit for purpose and wasting a lot of everyone’s time!

I have tried setting my gpu to mak.out at 1400mhz or so. Played for about 15 mins or so and it dropped to 300mhz. 

Rebooted laptop, set it to around 1300mhz and been playing for over 40 mins or so and has not clocked down yet. Temps stay in the mid 70c for gpu and cpu in the mid to high 80c. 

I did not do the cpu stuff. Just gpu. 

So far its seems ok. Will report back if something changes.

Thanks for this info!

Did you undervolt the GPU in afterburner (via the CTRL + F graph) or just reduce the core clock speed?

The undervolting is very important as it is overvoltage triggering the GPU shut down, not the core clock speed (though it is indirectly this, as high core clock limit will raise the voltage too high). Even at 1500mhz you could get over voltage as the bios throws voltage at the GPU to try and get it up to its factory 1900mhz limit. That’s why the undervolting of GPU is important as then the bios will not put anymore voltage into it beyond 0.8V, even if it wishes to reach 1900mhz (it won’t be able to get it above 1560mhz @ 0.8V per the graph in Afterburner). Hope that makes sense.

You can apparently run 1560mhz  @ 0.8V without getting a GPU shut down event (to 300mhz). I’m still doing only 1360mhz @ 0.8V and it’s plenty enough performance for me. Temperature of GPU did not exceed 62 degrees Celsius lastnight after playing for 3 hours, so staying very cool.

CPU did get up to 82 degrees but that isn’t too bad. I could still undervolt that down the track for battery longevity and cooler temps, but no desire to yet. Either way, I’ve had no 300mhz shut downs from the GPU so I’m happy.

I did the changes on the graph as per the instructions you gave. The voltage i believe is around 0.7 something. I'd have to recheck. At 1380mhz it's been fine so far. 

Cant wait to test it with other games to see how it works.

Sure, please check and confirm.

@DELL-Cares is there a way we can contact Dell and have them create a BIOS update for these laptops that removes the obscene factory GPU overclock they come with, given we have likely tracked down the source of the issue for them (GPU overvoltage shut down)? I feel it would be in their interests too do this, to avoid returns and warranty problems (GPU might be protecting itself with the overvoltage shutdown, but I don't imagine it's great for the GPU to get there often in the first place, heat etc.).

Thanks

Yep it's a logarithmic graph so 1380Mhz will produce a lower voltage than 0.8V does.

Give it a shot on 0.8V and see if you're fine with that too; I know you'll be happy just to be gaming without getting a GPU shutdown to 10-15FPS, but there's no reason you shouldn't expect adequate performance out of the card - it's a killer GPU for a laptop. It is also probably better to give the card 0.8V and 1560Mhz per the graph, and then use the core clock slider (on the main Afterburner screen) to shave off a further -200Mhz if you're keen for lower operating temperatures.

As the guys on the other forum suggested, the CPU and GPU share the same heatsink in these so if GPU is at a lower temperature then cooling for the CPU will be slightly better too.

lag spikes at 300 MHZI HAVE THE FIX!

I have the exact same problem - Brand new G7 7700 RTX 2070 - would drop to 300MHZ  with 100% Usage - massive lag spikes that you can temporarily fix by spamming the "G" button on /off. This would fluctuate between anywhere up to 1850 MHZ (normal) back down to 300 where it would gradually stay (and subsequent massive lag ensues).  I've noticed its always sitting on  92 - 100*C CPU temp and about 70*C GPU temp - searing hot to touch just below the "dell" logo at the bottom of the screen.

The problem is the Dell Alienware Command app - Do Not Use it.

launch your games via the Nvidia Experience App  - and make sure you've updated the game.

Download MSI - Afterburner to monitor your GPU / CPU usage. Since I've done this tonight, I've had no lag spikes, CPU and GPU temp is around 70 deg C. 

I'm now playing Remnant with everything on Ultra with 70 - 144FPS, and no lag spikes!

@Chilleus Outeus see posts above / read entire thread, please...

A lot of people have done what you suggest before, i.e. removed the Alienware software or run the game without it and their problem still persists - it appears to be sporadic in nature, giving false hope to some solutions. I'd be surprised if it doesn't come back to bite you, unless you changed settings in Afterburner to declock or undervolt like some of us have. People have found a 1900mhz limit in the Dell BIOS independant of the Alienware software; in my mind undervolting to artificially lower the clock limit remains the only sure way to fix this until Dell repairs the BIOS with an update.

Cheers
