Dell :: SXPS 1640/1645/1647 GPU Throttling
Feb 25, 2010Please note that my GPU Throttles down when it hits 84C. This cycle will continue up and down as the system system downclocks the GPU.

View 10 Replies View RelatedI just bought an SXPS 1647 (I believe... I have the core i5-540 processor) and I wanted to know how the throttling issue effects these models.
Is it less of an issue because the i5's are less power hungry?
Has there been any response from dell about the throttling on this model? Are people requesting the 130Watt adaptor?
System:
i5-540
4GB RAM

RGBLED 1080p Screen
I've decided to get an xps 16 for college, and I am curious as to which to get. I plan on using it for college, but also plan on playing quite a few games on it as well when I have the time. Which would be better overall to avoid throttling issues, and just have the best performance for this overall?
On a side note, on the dell site, how do I tell which is a 1640, 1645, and 1647?

So yes I have no cred and I am relatively new but I think we can all agree the direction of the heat vent on the XPS 16XX series needs to be changed to face downwards at least, so that the heat isn't dicipated directly onto the screen!
There doesn't seem anywhere available to add a secondary vent, so at least the primary vent needs to be improved.
I will send this to Dell_Bill_B as he requested in the throttling forum, and he said he would take this issue up at the next conference call!
For you people who are wondering: SXPS 1640 on left, 1645 on right.

I have a new 1647, I did a clean install of Windows 7, updated to latest Dell BIOS for this laptop and currently I am plugged in via direct connection (battery taken out) to a 130W power adapter.
I am using VLC to playback a 1080p anime video. For the most part, video playback was smooth up until like 10 minutes ago. Laptop is noticibly warm, VLC keeps buffering. I'm assuming it's throttling .....
This is interesting... a friend of mine just tried to order the SXPS with the i7-820 processor and got denied by Dell. Apparently, the 1645 has been fully discontinued, and Dell will no longer be placing the i7-820 processor in any SXPS form factor. They quoted that due to hardware and power issues as the reason behind discontinuing the 1645 (and replacing it with the 1647) and killing i7-820 support. The sales rep said the only offering will be the Studio series for the i7-820.
As a 1645 owner with the i7-820, this is kinda scary that this laptop has been discontinued this quickly as well as the offering of the 820 series chip. We ended up calling a second time, and another sales rep confirmed the same story.
Anyone get similar information from Dell on this? I'm also wondering if this is a "Dell Canada" thing...
I recently (Dec 7) bought a XPS 1645 and I'm experiencing the throttling issues. It's apparent when I play games (Left 4 Dead 2) and I have the RGBLED brightness set to high. If the brightness is at the max setting, the game is unplayable. If I minimize the brightness, the game immediately becomes playable. I have been keeping up with the throttling thread. From what I've read the upcoming bios update will not fix the issue. It has to be a combination of a bios update and new AC adapter. I don't expect Dell to send out 130w AC adapters after the battery fiasco they had - considering the 1645 was designed to use a 90w AC adapter.
This got me to thinking. If the bios update doesn't resolve the issue, there are only so many options that we have left.
1. We buy third part 130w AC adapters and hope that our laptops don't burn out.
2. We each individually call Dell Tech Support and stay on the phone until we get a refund/replacement unit (possibly the 1647?).
3. We roll over and use the throttled laptop and accept Dell's bios 'fix' - never getting the full performance out of our laptops.
4. Dell offers replacement units for affected customers.
Options 1-3 don't resolve the issue for us. As far as #4 goes, it's hard to imagine Dell issuing a voluntary recall on affected units. But I think option #4 is something that as a community we could make happen. While this issue seems to be fairly well known on the forums, (as someone mentioned in another thread) it is largely unknown to the outside world - based upon the reviews the XPS 1645 gets on Dell's website. If we were to go out and let others know how certain configurations of this laptop under perform, perhaps we make Dell notice enough that they would want to protect their brand by issuing replacements. The catch is that we have to loud and get this out there.
Dell won't voluntarily offer a product replacement. This issue is unknown. If they were to go ahead and replace our XPS 1645's, that would be letting the whole world they screwed up on the design on the laptop.
However, if we can somehow get this into the news cycle and let the world know, then it becomes in Dell's best interest to offer replacements.
On the featured systems, i was thinking of purchasing the second one which has the i7 processor, but i have a few questions before i would like to buy it.
1) This is a 1645 system meaning that throttling will be there right?
2) Does installing the A09 BIOS Solve the throttling issue?
3) Without using throttlestop is there any way to control the throttling?
4) Is it compulsory that throttling occurs on all the systems or some don't have it?
5) Will me playing NFS Undercover cause the laptop to throttle?....
Dell has released their solution to the throttling issue, if you have updated to the latest A07 or newer bios, and recieved a 130w adapter from dell. Need to call the reps and get a 130w sent free of charge.
After more testing looks as if the A07 bios has indeed greatly improve the performance of the laptop. More testing will continue to see where the limit is at, as there may be close to the throttling edge perhaps.
Purpose of this thread is to educate those about the throttling issues with dell's laptops. Specifically to the xps 16 with i7 processors. Also to show community driven solutions as we wait for dells response to this issue.
This is an advancement from the power investigation thread, to summarize the thread here is a quick list. The 1645 is supplied and designed for a 90w adapter which is undersized and cripples the laptop under gpu + cpu stresses,
such as gaming and photo editing.Running on battery seems to let the laptop run more towards it potential.The problem severity varies and depends mostly on configuration and type of program being ran.A 130w or bigger power supply will not solve the issue alone, as the bios actively throttles to main 90w anyways.Through reps Dell seems aware of the issue. As of yet there has been no official announcement and is .....
Hoping to buy one but wow, there are a huge amount of problems here.
If I order one now, will this brand new machine have these problems? Have Dell sorted this mess out?
In recent light of the the throttling investigation and incoming fix on the 1645 and 1647 models, Ive been instructed to make a separate thread to investigate the same issues for the 1640. If you have a 1640 with throttling issues please post any information in this thread. This is a new thread covering the same issue as the other problematic 164X's. Throttling.
Unclewebb can back me up on all of this as I went through these tests with him, the same tests he used to determine throttling on all other 164Xs models.
At full GPU and CPU load, mulitplier scales back to 6x and 3x. My 2.93ghz t9800 then clocks down to 1500mhz and 798mhz respectively.
Programs used: RMclock, CPU-Z, GPU-Z, 3Dmark06, Prime95, Throttlestop
For Bill: Original 1640 threads where users started reporting throttling. Joker first reported throttling on the 1640s when he had a 3670.

I am currently being offered a exchange for my 1640, and they are giving my the option to configure it.
Which is better? And how do i know which is the 1645 and 1647 on the website?
I have been testing my Studio 1557 today for throttling issues.The i7 does throttle down to the x10 multi under a 100% load on the CPU and GPU after about 10 minutes.
But it seems to be temp related not starving for power.
When my GPU hits 100c it will throttle back to about 88c.When the GPU does that the multi on the CPU goes from 10x to 12x (1.6ghz stock speed).While the GPU creeps back to 100c the CPU stays at 10x until the GPU hits 100c then back to 12x for a few minutes.
Everywhere talked only 1645 throttling problem and dell fix 1645 and so on.. If Dell fix 1640 throttling problem to?
View 3 Replies View RelatedThis has been happening lately ill be playing starcraft 2 ( other games as well ) but this one specifically that all of a sudden frame rates dip to 2 - 10 fps and the game crawls. Starcraft 2 gives me a warning saying my computer is running slow. I normally get 30 - 40 fps with a mix of medium/high settings at 1920 x 1080. Temps seem normal but my cpu usage is spiked at 100% when this is happening. I know throttling on the 1645 and 1647 is common but ive never had this problem with my 1640 until now. I have 2 years left of warranty so im ok. If i call dell what am i going to tell them and what are they going to do?
Below is a pic of temps

I'm trying to decide between the two though I lean towards the 1645. I'm also open to any of the doubters trying to argue for something else altogether.
I'm a gamer and a relative power user, but I don't fret benchmarks and I don't mind if I get some throttling after a few hours of gaming so long as the issue will go away once I quit to desktop and give the comp 15 minutes to cool down.
I'm also not chasing every last bit of graphical detail or processor power. If two years from now I can still play new games on modest graphical settings with an acceptable frame rate, and if my desktop experience is crisp and responsive .....

I posted a few weeks ago about how my 1640 might be throttling. While with unclewebb's ThrottleStop shows that when I run Furmark and Prime95, the multiplier of the CPU goes down to 3x.
I'm going to do some intensive testing tonight with my system and hopefully some other 1640 users could come out and test theirs since most of us have different configurations. (Please see my signature down at the bottom for system specs)
Also, I see that in the other thread about the S-XPS 1645, it was normal gaming that caused it to Throttle. Games such as TF2, Demigod, and D.A .....
I currently have the Studio XPS 1645. My uses for the machine are client visits, presentations, and occasionally gaming on the road.
I probably only log 5 hours a week on the laptop 3 weeks a month and 30 or so in the other week (when I am not at home).
I have read about the throttling issue and this is my last day to return. So knowing my usage pattern. Would you keep the quad core or change out for the 1647.
I recently returned my 1645 after 2 months of struggling with random crashing and throttling back to Dell for a full refund.
I am in need of a new system and was considering HP Envy 15 as an alternative, but I still like the 1645 given that it performs as advertised.
I seem to be having an issue with playing DVDs on my SXPS 1647. I have the Blu-ray combo drive (HL-DT-ST DVDRWBD CA10N, with firmware A109).
Every few minutes you can hear and feel the drive start clicking. When this happens, the playback starts stuttering for a few seconds. This doesn't seem to be an issue when playing Blu-rays.
The drive still clicks every few minutes, but the playback doesn't stutter. Is this normal that the drive should be clicking every few minutes? I checked to see if there was a newer firmware version, but the latest version on Dell's site was A108.
So I have a 1640 with a t9900 3.06ghz processor being replaced with a 1647 i5 540M processor. Does the t9900 outperform the i5 540M?
On notebookcheck.com the i5 540M is rated lower than the t9900.
Been following all the throttling issues on these forums religiously for a while now. I have been eyeing these laptops since they came out. Looking for some opinions on what I should buy. The "business" reps are trying to sell me a Precision but that price point is really high.
Primary uses will be:
Software and Database Design and Development -- mainly C++, .NET technologies (WCF, WPF, C#, etc), Silverlight, Sharepoint, Expression Blend, SQL Server (not express). I will be installing the entire development environments and tools that come with these. Also MS Office Enterprise.
Other occasional uses:
Movies (getting BR for sure), some gaming (not hard core like most here) and other regular day-to-day tasks (surfing, etc.)
With above said, should I get the i7 620, 720 or 820? I can get the RGBLED with the 620 but not the 720 or 620 -- is the RGBLED worth it -- don't mind spending the $$ for it -- or is the WLED just fine (even for BR movies)? Also, I am definitely getting the SSD for speed.
today I bricked my new 1645 when I was examing the BIOS for the 1647. The BIOS release 1647_A00.exe released this month automatically begins flashing on an 1645
and does not seem to check compatibility or confirm with the user before it updates.
The BIOS is completely incompatible with the 1645 to say the least, so be very careful if you download it on to a non-1647 system.
Dell is building a new system due to this really sad event. Rip XPS 1645 - December 5th 2009.
Looked around here but could not find the answer. Are there actual hardware differences between the 1645 and 1647 xps studio 16? Just curious if the 1645 can handle the next gen procs (i5, i7 Arrandale cores). Also can the bios for a 1647 be used on the 1645?
I got forced a 1645 in a system replacment and they would not do a 1647 even after they said they would and I pushed HARD on my end. I now wonder really what the hardware differneces are if any?? Also want to know if this thing will allow future upgrades as to the cpu past the Clarksfield cores it runs now?
Also mine did not come with the SB x-fi software. Is this worth asking for or obtaining?
When I logon to Win7 it hangs at 'welcome' for quite a while, then goes to desktop and has the loading cursor while my desktop icons load, then my antivirus loads.
It isn't crazy slow, it is just a lot slower than my M1530 which was instant. Am I just noticing the difference between my 5400rpm drive and my old 7200rpm drive? Is it a significant difference? I will be poppin in another WD Scorpio Black
I was giving my 1645 a nice cleaning when I noticed a depression on the left hand side palm corner. The black of the palm rest actually sinks below the the silver trimming. Is this normal? is it supposed to be flush? Does it mean I need yet ANOTHER part replaced on this damn laptop?
View 10 Replies View RelatedI am one of the many people here who has a defective Studio XPS 1645 (random crashing and throttling issues). I was promissed a replacement system by a tech support supervisor and Studio XPS 1647 was mentioned by him as a replacement for the 1645 system which will fix all outstanding issues (as claimed by him). I don't have a detailed system configuration yet and will post as soon as I recieve one.
I just don't want to be a beta tester for Dell once again if 1647 proves to have design flaws like the 1645.
Does anyone out there have 1647 yet? Is this an upgrade to 1645 (hope its not a downgrade)? Should I accept this offer or demand a full refund?
