ST1747: 7x Bios beeps - Core i7 throttling - too less A/C adapter
more and more ST1747 users reports about reducted clock rates of their Intel Core i7, if similary their graphics adapter (ATI HD4650) is under heavy load! But the worse is yet to come, some Core i7 quits working, 7x Bios Beep, Game over, sudden death of the CPU! :emotion-45:
Update: the 7x Beep issue seems to be fixed since Bios A06!
UPDATE 03.2010: STILL OPEN ISSUES OF STUDIO 1747 / BIOS A07
if you have more suggestions for this list, don´t hasitate to inform/contact me!
►Core i7 Throttling
under simultaneous full load of CPU and GPU, Core i7 CPU throttles down to averaged 4x 1100 - 1400 MHz
►Performance between battery and AC power
most Studios runs with a bit more performance if only battery is connected
►Hot 90 watt a/c adapters
under fully load, the serially 90 watt adapter seems to work at/above its performance limit - temperatures over 70°C are not acceptable
call your local Dell support for a free 130 watt adapter.
►Problems resuming from sleep and/or hibernate
if the 1747 "sleeps" more than 30-60 minutes it´s possible that it don´t resume anymore but turn it off&on "hard" by holding power-button
►Problems with playing FullHD-Streams
freezing/jerking, max. loaded and almost non-responding Studios if playing a FullHD-stream, e.g. Youtube
possible solution, please look here. New Dell ATI driver in progress.
►Permanent running fan
fan starts causeless running at increased speed shortly after turning the 1747 on. Fan keeps blowing at increased speed, even if Windows boots all over and CPU idles - because of the still-blowing fan only at ~32° C. You can stop the fan only with a reboot or by stressing CPU - if temperature reaches 48°+C, fan slows down to lowest level. Turn off stress test, temperature drops below 48°C, fan turns off then. Confirmed by several users. 4 new users reported me this curious issue in the last few days!
►Too less temperature range for fan
fan needs an extended temperature range in office mode. At the moment fan turns on at ~53°C and off at ~48°C. That causes the fan to start&stop every 10-15 seconds, very bothering
►Cutted sound
If the IDT sound "idles" for a while and you play then any sound, the first ~0.5 seconds are cutted! This happens only one time, following sounds are played correctly! If you stop and wait a few minutes, the next sound after this idle time is cutted again
►Not enough power to USB ports and Firewire
There are pages upon pages of various users all experiencing the same issues.
take also a l@@k at German Studio 1747 FAQ @ Hardware Luxx forum | sorry for my rookie englisch! ^^

Todd,
I have 1747 order that is processing. I was unaware of these problems when I ordered. In your quote above you talk about what is realistic. Other people in this thread have said that there are other similar computers from other manufacturers out there that do not throttle under any circumstances thrown at them. Would this not indicate that there is a design flaw in the 1747? These may not be a real-life tests, but they do indicate that it is possible to build this type of system and not have this problem. Shouldn't the 1747 be able to do what your competitors' equivalent products can do? To me that is really the question and I believe the answer is that your product is inferior. As a purchaser, if I'm going to compare the Dell 1747 with other companies similar computers that have very similar specifications, and I find out that the Dell Computer throttles and the other ones do not when using the same tests, why would I go with Dell? Since I have already made my purchase (which I can cancel) I would hope that you would agree that if the other guys can figure out how to do it, and you are advertising basically the same product, yours should not have the problem it seems to have. Comments?

[/quote]Mitch,
I guess I would need to ask which models are you comparing it to? You can pull up some of the competitor systems and compare them. Are they the same systems and are they at comparable prices? People have mentioned the Envy in comparison to the Studio 17. I don't have time to do an in depth comparison of specs, etc, but there is definitely a difference in starting prices.
Is that by any means a complete comparison? No, and I don't mean it to be. It's easy for someone to say on a message board that someone else's system is better but when you really get down to it, are they comparing apples to apples? I'm not sure. that's why I tend to stay out of the comparisons to competitors. It never really works and this will probably be the last time I get involved in these sort of discussions.

The Studio 17? As others have posted they are currently available in some regions or countries. I would guess that it has to do with parts availability.

Todd, could you explain why these computers seem to have been pulled from the website for purchase?
Incidentally, I was comparing it to the following which is available for $1099 plus tax and shipping. Seems pretty equivalent to me(at least to the studio 17 I had configured and have on order)and:
HP Pavilion dv7t Quad Edition customizable Notebook PC

You wrote: "The Studio 1747 isn't one of the systems designed to handle max load utilization of both the GPU and CPU at the same time". (12 Feb 2010 01:21PM)
Can the customer expect this, before he buy it????

I think to be fair to the others that you seem to be attempting to help you should make clear what you're quoting. Can you show people where I said they can't use the CPU and GPU simultaneously? Because if so I'd like to go back and clarify my statement. Because that is not what I said, or intended to say.
What I did say is that the system isn't designed to run both at max utilization simultaneously and that is a very important distinction that you left out.
Are we wrong and the system isn't working as designed? I'm always open to being proven wrong.
I'd really like this thread to get back to people posting helpful information.

When you buy a computer, analyzing its components: CPU, GPU, RAM etc. ..
According to specific conclusions are drawn.
If my CPU is a 720qm I know that its frequency will be at least 1600 GHz, and the same applies to ALL members, whether they work together or not! is the set of components to make the intended use, not its marketing people.
So please, do not say it is a multimedia computer, because it is a phrase without meaning.
The same applies to the speech "real world" because it is unpredictable situations that will meet all the users of a computer.
The only guarantee is that everything works as it should work!
At the conclusion you arrived XPS 16 to replace the power supply, but do not want to do the same with the Studio 17, citing the difference in hardware ... What differences?
Processor is the same, the GPU is basically the same, I have the Full HD, Wireless N, ETC. Where are the differences in consumption justifying 40W less??!

As You said, Todd. Revisit problem and make, us, users satisfied.
1. Give us more power full PSU.
or
2. Replace motherboard and ATI 5730 for example.
I think it will do the trick ;]

Dear Todd
May I remind you that the Studio 1747 is not throttling when running on battery (according to community findings using BIOS A03, I think)? This shows, that the notebook can handle simultaneous CPU and GPU stress at 100% -- without throttling.
@ ALL: Has anyone with A07 BIOS installed already done a stress test while running on battery? What are the findings? Is battery operation throttled now the same way as when running on power supply or still unaffected by throttling?
PS: Todd, I do not want to have your job at the moment.

Hi!
I made some tests today and it seems that most of throttling is fixed with BIOS A07.
I made a test with Prime95 and GPUTool. With A01 - A05, CPU was throttled to 1,1 - 1,3 GHz. Now with A07, CPU stays at 1596 MHz (measured with CPUz and CoreTemp64). Only when I overclock the graphics (575/730 MHz instead of 550/700), core speed is reduced to 1400 MHz.
Still I have two other issues: the fan control and the incredible hot PSU...

I'm not a power user like some and I don't test my systems like some of the above posts but I have 3 concerns:
1. Sound. Whenever the fan goes on or off, which is frequently, it makes any headphone plugged into the computer pop with static. This is incredibly annoying and is why I haven't up dated the bios because the updates make the fans run more.
2. Hot power brick. Mine is very hot while playing games, mostly world of warcraft. I can not hold it on one end of the brick because it gets so hot.
3. Performance. I bought this system with the future in mind. I play games and wanted something that future games would use the quad core in it. It runs fine now but it seems like future performance may be hindered by design when more advanced games come out. I bought this system based on the sum of its parts. I know that based on their interactions, you can get a varied level of performance. I did not expect the system to run under its capability because Dell has throttled it. When the ad says 1.6 cpu up to 2.8, I expect that. If the ad said that it would be throttled, I probably wouldn't have bought it. I hope Dell makes this right one way or another. It reeks of false advertising and poor testing.
I appreciate the company feed back on this board. I realize you are caught in a very bad situation. Please pass it on that we just want the system performance that was advertised and we paid very good money for. If that means a new motherboard great, or a new power supply fine, but please keep us updated and don't sweep us under the rug.

Hi Todd - Just wanted to highlight a few issues with my studio 17 Bios A06.
1 - I have discovered the following warning in the event logs for all the processors - Not sure at what point they occur...
Log Name: System
Source: Microsoft-Windows-Kernel-Processor-Power
Date: 11/02/2010 22:14:14
Event ID: 37
Task Category: (7)
Level: Warning
Keywords:
User: SYSTEM
Computer: Admin-Studio17
Description:
The speed of processor 1 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 3 seconds since the last report.
2 - Every time I try to watch a youtube video or a flash video in fullscreen my laptop just shows up a black screen and I cant do anything. The sound continues to play fine, the only resolution I have at this point is to hard shutdown and start again. Since I have disabled Aero and have set Win 7 to run my system for best performance rather than best appearance - I have not had this issue - Youtube and flash video play fine and the system runs a lot smother but without the good looks of Aero.
Log Name: System
Source: Display
Date: 11/02/2010 19:32:07
Event ID: 4101
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: Admin-Studio17
Description:
Display driver atikmdag stopped responding and has successfully recovered.
My spec: 1747 - i7 820 - 6gb ram - 500gbx2 - 900p touchscreen.
--- Can you try to get me some help in these matters - especially the second one. Let me know if you need more info.
I think its about time we all started to appreciate the fact that someone is actually listening to our concerns and feeding them through the right channels... No point taking our frustration we have with DELL out on Todd or any other employee.
Thanks

I had a look at that log file and Clock Modulation was at 100.0% for the entire log. If clock modulation is dropping down to 50.0% can you post a log file of that.
When there is a load on your CPU the multiplier is up around 18.0 or 19.0 which is where it should be. Because your test is not a synthetic test, it can be hard to understand how much load was on the CPU at any point in time. The drops in the multiplier down to the low 7.0 range might be the result of Intel SpeedStep dropping the multiplier when the CPU is lightly loaded. With your log file it's hard to tell.
Windows 7 works differently than previous operating systems and some motherboards are dropping the multiplier when lightly loaded even if the Minimum processor state is set to 100%. You can check that setting in the Control Panel -> Power Options.
Hopefully users can post some more log files. I hate throttling as much as anybody but if this is still a problem during normal gaming or normal use then a log file that clearly shows that will be hard to argue against.
blackpiranha: CPU-Z and CoreTemp64 can be misleading. Neither one of them properly reports clock modulation. The MHz and multiplier can be reported just fine even if clock modulation is being used to slow your computer down significantly internally. If you want to test those tools, download ThrottleStop and force Clock Modulation to 12.5%. Run any simple benchmark like Super PI mod and you will discover that your computer is running like a slug. Can either of those two tools report the performance of your computer accurately when clock modulation is being used? The minimum multiplier for a Core i7-720 is 7. Any software that reports a multiplier lower than that is not accurate. What multiplier does CPU-Z report when clock modulation is being used? A screen shot would be great so other users can understand this better.

Hi,
Same as u, my 1747 will delivery at 24Feb at Hong Kong, I asked for order cancel if throttling issues cannot be fix (8 Feb), but CS reply me that its too late to stop the order.
If i note that : The Studio 1747 isn't one of the systems designed to handle max load utilization of both the GPU and CPU at the same time, i will not make this purchase!
Come on, why I pay a i7 720QM + ATI 4650 combo if they cant work fully load similary? If a 1.6Ghz CPU only work on 1.3GHz with this notebook configation, why I need pay for a 1.6Ghz?
Many customer like me don't care a little diff prices for a 130W+ PSU.
U should tell customer that 1747's CPU speed may drop in some working conditions! Like SONY do this on its VPCF117 spec at SONY Hong Kong web site! I will choose other dell model other CPU or other band if i know it before purchase.

Agreed, He's doing the best he can with what he has to work with. The issue right now sits with the engineers. They're the ones that "green-lighted" this configuration for production. They have the most face to lose. What I find interesting here is that the problem seems to become non-existant if the end-user is running off the 85Whr battery (from what I've read). If this is the case, then either the battery is providing more power (e.g. 130W) then the 90W AC Adapter or there's something else going on. I'm guessing it's the later. I know Windows 7 operates significantly different when running off the battery, then it does when plugged in. I also know that a lot of manufacturers will set the power management profiles to maximize battery life, or they'll even go a step beyond e.g. Toshiba and preinstall their own power management software when it comes to laptops. If these profiles aren't changed out of the box, the laptop will underperform all the time, even when plugged in. This will also greatly influence benchmark software as this software still has to run on top of the operating system. I don't have the laptop to test yet, but the ideal test enviroment for the hardware would be a bootable CD that completely bypasses the operating system.
