With CPU voltage offset(-0.125v):

 

Wait a second, did you get undervolting working on 13th Gen Precision?

Of course, just enable the overclocking option using grub.

I have made that change but the new "Dynamic Overclocking Undervolt Protection" (CpuSetup offset 0x381) remains enabled so changes made via Throttlestop were not being applied. I am running the latest bios which has microcode version 115. If you apply an undervolt, then read the undervolt value from a different app like Hwinfo64, does it still show the offset as active, as it did on the 7670?

Cleaning the fan still requires dismantling the entire heat sink.  I miss the legendary 6700&6800 so much.

The fins are plenty with small gap, normal cotton bud won't work anymore, need something flat.  Brushing won't work that good at my place, the dirt is simply just too much.  Imagine this machine is just 2 months old.  the fan is spinning hard so i decided to clean it.

OK, yeah, it pretended to be undervolted. My bad, it did nothing in fact.

I have replaced the heatsink assembly, but nothing improved.

is the temperature difference between the cores still large under full load?

 

Wait some time for the system can run a few heating/cooling cycles and the pad can adapt to different pressure levels due to uneven contact.

Also check Throttlestop limit reasons while under load to see if its BD Prochot causing the throttling. I had that going on (especially on combined loads) where it would randomly drop the CPU down to 30W despite temperatures being 70C and GPU drawing around 80W and DPTF/IPF/DTT disabled. BD Prochot is 0x7a in CpuSetup if end up needing to disable it.

Yes, but the core temperature mapping is different now, core 0, and 1 are not that hot. The cores in centre (5, 6, 7 and two clusters of E-cores) have higher temperature than two sides.

Still, the heatsink has problem and I am asking dell to replace another one for me.

This is to confirm that the WWAN slot can support up to Gen3 x2 b+m key 2242 NVMe SSD (x3 and above will not fit).  The best possible ssd could be WD SN520 ...

 

With ssd on WWAN slot, it will guarantee a crash during every laptop startup after shutdown, with windows BSOD error code of "Internal_power_error".  The laptop will restart and the next reboot will load the Windows normally, and the wwan ssd works like normal.

 

It is unknown of how to tweak the bios or windows setting to avoid the first crash.  Not many people is using this slot for ssd.  Once I removed the wwan ssd the crash is gone.

Hi all,

 

Good news for me today, Dell informed me that given the problems I'm having with my Precision 7770 and the disastrous order process for this model, they were going to exchange it for a new 7780.

 

I received it today

Despite all the bad stuff that goes on with Dell, more often than not they will come up clutch for their customers. Enjoy your newly upgraded machine.

I'm completely agree with this, however I persist in saying that people who only have access to level 1 of support are more penalized than those who have a dedicated sales contact.

Good news here:

48GB*2 5600MHz SODIMM works pretty well on 7680 (running @5200Mhz bcz dual channel)

 

 

Which brand are u using? SK or Crucial? in Dell specsheet sodimm 64gb is 5200Mhz, so 96Gb still can get 5200 is considered good not dropped to 4800.  Only up to 32GB will run at 5600Mhz.  This is set by Dell bios i think.

Hey, anyone with a 7780 equipped with a 13950hx or a 4090?

 

I'm being offered that as a replacement, but I can't find any info on how much power they can draw, I want to know how much performance I can expect (I've seen similar in this thread though), if someone has some cinebench r23 results or hwinfo cpu power consumption at full load, I would appreciate it. For the 4090 I would also like to know how much power it can draw, I've seen the Nvidia panel says 145w or 150w, but haven't seen benchmarks or hwinfo showing that sustain consumption yet.

Yes, here is the information I gathered from testing the 7780:

 

The CPU can draw up to 157W short term, and 85W long term. This results in about 30,000 in Cinebench from a cold boot, and sustained around 24,000.

 

The GPU can draw up to 145W but its going to only be around 135W-140W on average with Nvidia PCF managing power.

 

Intel IPF (similar to DTT/DPTF) can float the sustained CPU TDP between 30W and 85W. It can be disabled by blacklisting device ids or by using Throttlestop and locking MMIO limits. BDProcHot can also be triggered which can put the CPU and iGPU at very low clockspeeds for a period of time. It can be disabled via modding a UEFI hidden setup variable.

 

Unfortunately the dGPU performance can randomly be reduced at times. The best way to reduce this from happening is keeping the back raised in some fashion to help keep sustained temperatures lower. Also place the power supply somewhere it can dissipate heat easily. I use the 330W Alienware non-SFF brick at my desk as it stays much cooler than the 240W SFF brick.

 

All of the problems mentioned above aside, it is still a good upgrade to any previous generation. Oh, and if they ship it with SODIMMs you can use the 64GB Kingston Fury kit at 5200 CL42, and likely the 96GB kits work as well.

Thanks for the info!

 

that's honestly more than expected by reading the thread, did you repaste? it seems to be that PTM7950 is the current best option, I'll get that one plus the IETS GT500 cooler, it should be a nice general improvement.

 

This is my first Precision, the replacement is for an Alienware x15 r2 (12900h, 3070 ti). my usage is mixed between working and gaming, I like the more professional look too.

 

I did get it with SODIMMs (32gb 5600) so it seems I won't have to buy the adapter, I'll look for the 64gb kit or alternatives, thanks for the tip!

Yes, repasted with PTM7950 on the CPU and GPU. It doesn't have any fan control compared to the Alienware, other than some of its performance modes have a different curve. However you do not have to deal with AWCC either which I consider a plus. I am surprised that they offered an exchange for an Alienware. Is it a new build or was it a refurbished model from the outlet? They do also have the new Precision 5680 there too, which may be a bit closer to what the Alienware x15 r2 was. I have no doubt next year it will be what becomes the XPS 16.

It was new from Dell's webpage (around 2300 usd total), bought in the US then transferred the warranty to my country, they said for my region the Alienware's stock was limited, this was their first replacement proposal.

 

 

My experience with the x15 was awful, so I'm happy with the upgrade.

 

The 7780 It's a new build, currently in "Production"

Well that is a nice upgrade they gave you. I would say that config is more like 4500usd!

[tolnep]

just got my 7780. 64 gigs, top i9, 512 mvme in bottom slot

17.3" UHD 3840x2160 WLED WVA, 120Hz, anti-glare, non-touch, 99% DCI-P3, 500 nits, IR Camera, with Mic

NVIDIA RTX 3500 Ada 12GB GDDR6

windows 11 pro

 

installed a 4tb nvme m2, installed windows datacenter 2022 as dual boot (required a bit of trickery)

 

my main use is vms and db stuff (oracle, postgres and sql server).

 

runs warmer than my m4800. same temps in win 11 and server versions.

 

wish it was a bit thicker... wish the battery was easily replaceable (ive always had a backup battery on hand during travel)

 

overall a nice unit. will it last as long as my m4800? time will tell.

 

eta to say... called dell to confirm signature required. fedex dude put it on my porch and left. no signature, no contact. would have been a haul for a porch pirate. bit upset by that

Would this kit be compatible (7780)?

Looking for any option for 64gb 5600 cl40

Looking for any option for 64gb 5600 cl40

This memory is compatible with Alienware M16/M18 and it appears that it activates the XMP profile automatically to run at 5600MHz CL40 with 2x32gb.

 

I believe it can also work with Precision 7680/7780 since it is stated that these have the same compatibility with XMP memories in relation to the Alienware mentioned.

 

Intel® XMP 3.0: Memory Profiles for Intel® Core™ Processors

 

Just testing to be sure!

Hi, 

i tryed to change the power limits with throttlestop on my 7680. I will set PL 1 to 90W and PL 2 to 120W. The change on PL 2 will work, but the PL 1 change will not work, PL 1 will always be around 77W. A lower PL 1 (e.g. 60W) will work, but not a higher. Has Dell this blocked?

 

Kind regards, Sascha
