==>The Official Studio XPS 1640 + ATi 4670 GPU Owner's Thread <== *Part 2*

The i7 takes a heavy toll on battery life. If your concern is battery life go with the C2D. Ironically though the 1645 has less heating issues than the 1640 (which is the C2D system).

 

hmm..ok..well battery life is a concern but not a major one..

Could i get any figures(time) as in how an i7 1645 will run in a single charge ?

what is the difference in performance in the c2d and the i7??

also im getting an alienware m15x for approx 560$ extra..in the config everything seems to be the same other than the Nvidia gt 260m gpu??

i was wondering if spending that much extra is worth it ?

 

Noticing some slow down (long load times in games) on my machine I ran HD-Tune and it shows this:


I normal chart i believe should look something like this:


I don't have an HDtune image for the machine before i started installing games and encrypted the drive.

Since i first setup the machine I have added maybe 80GB of games and used truecrypt to do a full disk encryption. I am wondering if this is the source, but most truecrypt forums say it only has a minor performance impact. Anyone have any experience/thoughts?

 

Guys, here's the solution to the RGBLED problem with the over-saturated colours (especially reds)...

Has anyone tried running ThrottleStop to see how much the XPS 1640 throttles during normal usage while gaming?

http://www.fileden.com/files/2008/3/3/1794507/ThrottleStop.zip

Leave the first 4 items unchecked and then turn on the Log File feature and go play. Post a log file or upload it to www.sendspace.com and post a link. You could also try doing some Prime95 or Furmark testing.

peppe1: That looks like a sick hard drive to me. You can also try HDTach to see if it shows the same thing. You might have to run that program in compatibility mode to get it to work properly.

 

How much people here have the cpu throttling problem with XPS 1640? And what spec..

 

my xps1640 throttles heavily under gaming..i just turn throttlestop on then off it again just so the multiplier jumps to 10.5..

Specs:
T9600
ATI 4670
320gb 7200rpm
WLED 15.6" screen
Bluray drive

 

Why not post a ThrottleStop log file while you are gaming with ThrottleStop just monitoring your computer and not changing anything? Don't have any of the first 4 options enabled.

Dell is just starting to take the throttling XPS 1645 problem seriously. They seem to need a lot of users mad as hell before taking anything seriously. A log file is great documentation and is difficult to argue against. It will also counter the myth that the Dell sales reps like to tell that the XPS 1640 doesn't have any throttling issues. Yea, sure it doesn't.

The early T9600 supports Intel Dynamic Acceleration so it can use an 11.0 multiplier when only a single core is in the active state. This happens automatically but you need to have C3/C6 enabled in the bios for this to work. The TS log file should show average multipliers between 10.5 and 11.0 when this is enabled and working correctly. When playing with the Set Multiplier option in ThrottleStop, make sure you have the Voltage as high as possible first to avoid a lock up or BSOD.

When testing for this don't run RMClock because it doesn't support the half multipliers correctly and can interfere with ThrottleStop.

 

I have the 2nd to highest cpu config for 1640, t9800. My CPU is undervolted with RMclock. I also use RMclock to force a pstate of maximal performance of an 11x multi which is 2.93ghz. I game a lot and Ive never experienced throttling. Even without the undervolt and locked p-states, I never experienced throttling.

 

tenknics: For your T9800, does the multiplier adjuster in ThrottleStop go any higher than 11.0? Don't put a check mark in any of the boxes. I'm just curious how it reads your CPU and if your CPU supports Intel Dynamic Acceleration (IDA). The Intel documentation for the T9800 is limited.

Edit: It looks like it does support IDA which means RMClock is not letting you use the full performance of your CPU because of its lack of 0.5 multiplier support. Your max multi when C3/C6 and IDA is enabled correctly is probably 11.5

http://www.intel.com/cd/channel/res...obile/processors/core2duo_m/feature/index.htm

 

OK but the T9800's max multi is 11 regardless of what RMclock supports or not. The t9900 is 11.5. And I yes I know my CPU supports IDA because I always try to turn it off in RMClock but it won't stay off. I think its locked in the dell Bios. The reason I noticed it because my clocks would stay at 2.93ghz but my voltage would raise sometimes for no reason..From what I read IDA isn't that great and doesn't work very well. It's not like turbo boost. I dont understand what this has to do with throttling?

Isn't the throttling issue about not maintaining stable clocks with the 90w power adapter? My clocks are always at 2.93ghz when Im plugged in, regardless of what Im doing. Only battery do my clocks go down because I dont have a pstate locked.


Btw, Im re-reading over this 1645 throttle thread again..Why can't RMclock solve the issue by just locking the P-state to its max multi?

 

The default multiplier for a T9800 is 11.0 but if your CPU supports IDA then that means your CPU can use an 11.5 multiplier when one core is in the active state while the other core is in the C3/C6 sleep state. This happens automatically.

IDA works fine and it's exactly the same as turbo boost on the newer Core i processors. The only problem with it is that it only gives about a 3% boost in MHz which is not really noticeable. It was a good idea by Intel but when the multiplier only increases by +0.5 and only when a single core is active, it's tough to notice any significant difference in performance.

The problem is that RMClock does not support the new Core i7 CPUs. It also doesn't fully support the 45nm Core 2 CPUs with their 0.5 half multipliers. RMClock hasn't been updated in two years and likely won't ever be updated again.

That's why I wrote ThrottleStop. I'm trying to develop something that works correctly with the newer CPUs.

Some XPS 1640 computers severely throttle when both cores are fully loaded. The multiplier drops down to 6.0 and then SLFM Super Low Frequency Mode is also enabled so instead of running at say 2400 MHz (9 x 266), the computer is only running at 800 MHz (6 x 133) when fully loaded. That kills gaming performance.

If you are using RMClock to lock your p-states then that's why throttling is not an issue for you. Thanks for your help.

 

No problem. But from what Ive read IDA doesn't work that great and doesn't always work when it is supposed to and it doesn't work every time when said conditions are met to activate. Why I have never seen a 11.5x or a clock increase when the voltage goes up (without RMclock locked pstates)?
Btw I turned off IDA in BIOS and now it stays off in RMclock, to correct what I said in my previous post.

You seem to know more about this so Im just asking you, this is purely out of curiousness as Im not experiencing any of these problems: For those with definate throttling issues on the 1640, will it throttle even with a locked p-state? Im asking because if it doesn't, then for those with core2/1640s cant they just solve it with RMClock?

 

Most users judge IDA based on what CPU-Z has been telling them which isn't accurate at reporting IDA. That's why there is a lot of misinformation out there about this subject.

ThrottleStop uses the method that Intel recommends to determine the multiplier. When a CPU is loaded, it is extremely accurate because it is using two high performance timers for each core that can run at a billion plus cycles per second. With this method, slight multiplier changes can be detected and accurately reported very efficiently. CPU-Z sampling one register once per second doesn't give you an accurate reading of your multiplier when IDA is engaged or when a CPU is idle.

For the Dell XPS 1640 which has a Core 2, using RMClock to lock the p-state should work fine.

Some laptops are using chipset clock modulation which is a way to slow down and throttle the performance of a CPU internally. RMClock does not support some newer chipsets so it gives users no way to adjust this. On the chipsets that it does support, you can manually change the chipset clock modulation setting but there is no way to block this from happening. RMClock has an option to block this but on my chipset it didn't work.

I was helping the Acer users with this problem and they had to leave RMClock open on their desktop and then when they were playing a game and it slowed down, they would have to ALT+TAB out to the desktop, adjust RMClock to restore full performance and then continue with their game. Doing this every few minutes was not ideal. ThrottleStop can handle this automatically so users can finally use their computers for gaming at full speed. The Alienware M15x also uses chipset clock modulation for throttling purposes. I wish I had access to 101 laptops from different manufacturers so I could test them all but I don't have that so I have to rely on user testing.

RMClock is a good solution for you because you have an even multiplier and you're not interested in IDA. If you had a CPU with a default 10.5 multiplier, you would be limited to 10.0 when using RMClock since RMClock does not support half multipliers.

I would like ThrottleStop to become a smaller, easy to use alternative to RMClock with better support for the 45nm Core 2 CPUs as well as the newer Core i7/i5/i3 CPUs and chipsets.

 

Thanks for the very informative reply. Very interesting stuff!

Also just out of curiosity. How is it that some people experience throttling on their 1640s (with Core2) and others dont? There is no chipset clock modulation..

Ive read people wtih t9600's and t9550s have throttling but with my t9800 I dont..I dont get how that works? Unless I had throttling prior to discovering RMclock? (which I doubt because Ive never experiened a performance drop in anything I do)

 

Do you play any 3D games on your laptop? This seems to be the easiest way for throttling to happen since this task works both your CPU and your GPU at the same time.

The easiest synthetic test is to run Prime95 and Furmark at the same time. This puts a huge load on a computer and an XPS 1640 will tend to throttle severely with this load. Try first with just Prime95 and see how that goes and then start up Furmark and watch what happens to your multiplier.

If you are going to do some testing then you need to turn off RMClock or only use it for monitoring. You can also use ThrottleStop to monitor your computer by selecting the Log File option. The More Data option will increase the frequency of data going to the log file.

Is your power adapter rated at 90 watts?

A lot of users experience throttling every day but have no idea what's going on. I think ThrottleStop will make it easier to monitor for problems.

 

Yes I've gamed, and I used GPU-Z to monitor and make sure my clocks were maxed (ATI Powerplay) on the GPU and they were, I turned off my P-state and saw a solid 2.93ghz in a 1 hour session of Dota (Warcraft 3) with all details maxxed at full 1080p, no throtting. Also tried using orthos for an hour and no throttling either. Yes my power adapter is rated at 90 watts, its the one that came with the laptop. I am downloading 3dmark06 right now. Will run with Prime95 and report my findings on my next post.

 

OK so here are my results:

You were right Multi dropped to 6 right away and went back and forth between 6 and 3 on ThrottleStop and 6 in CPU-Z. Just to see what would happen if I turned RMClock p-state lock on. Reran tests. Throttlestop and CPU-Z both reported full 2.93ghz w/ no throttling but when I looked at the RMclock monitor one core was at full 2.93ghz while the 2nd core was throttling and wouldnt go above 1.5ghz. So it gets throttled even with RMclock pstate lock. When I turned prime95 off and just ran 3Dmark06 both cores were at a full 2.93ghz and the 2nd core didn't throttle.

This is very interesting. While I dont quite understand all of it..My question to you is, why is running Prime95 necessary? I get that it maxes out the CPU so you can get the best results but I feel like that purposely taxing the system so it will throttle. Who's going to run prime95 while they game anyway? when I just ran 3dmark06 by itself I got no throttling what so ever on either core..Wouldnt that better represent a real world gaming scenario more?

Im not saying you're wrong, so I hope Im not coming off in a bad way. Just purely curious with lots of questions.

 

I guess the point this test makes is that when fully loaded, these CPUs are not supposed to be dropping the multiplier down to 3.0. What a reading of 3.0 represents is that the actual multiplier has been dropped down to 6.0 and then the computer has enabled SLFM which cuts the bus speed in half internally.

6.0 X 133 MHz = 800 MHz

Not all software can report this correctly but that is what is actually happening internally. ThrottleStop is monitoring the internal timers which show an effective multiplier of 3.0 so it reports it as this:

3.0 X 266 MHz = 800 MHz

I think the newer versions of CPU-Z might also show a 3.0 multiplier now. How it's reported isn't too important as long as you realize you're only at 800 MHz.

I'm not sure if the RMClock monitor is 100% accurate when this is happening. When you have situations where SLFM is being rapidly enabled and disabled hundreds of times a second, most software is not going to be able to accurately measure this unless you use the high performance timers that Intel designed for this purpose. I'm not trying to pat myself on the back or anything like that. I just want you to know that software that doesn't use the Intel method may not be accurate during unusual situations like this.

I agree that Prime95 + Furmark is an excessive load but it makes for a quick and easy way to test for throttling. A new XPS 1647 with a Core i7-620 Dual Core was able to run this load while maintaining its full 20X default multiplier so there was no throttling whatsoever. It's becoming obvious that many laptops can't run this much load without throttling.

Some newer games like Crysis are putting a bigger load on CPU and GPU simultaneously and are causing problems on some laptops. Even adjusting the brightness of the screen to its maximum might be enough to go over the edge and for throttling to happen while gaming. Users with systems similar to yours can be down to 800 MHz during the middle of a game which just kills performance and makes this computer unusable to play some games due to throttling. I think Warcraft 3 is not known for being a demanding game on a computer.

I like ThrottleStop because it makes it easy for users to accurately log the performance of their computer while gaming without putting a significant load on it. Now that we can easily monitor for throttling, more and more users are discovering the real reason why their computers are slowing down in some situations.

The old story that it's a laptop so you shouldn't expect it to be able to play a game is BS created by some manufacturers. There's no reason in the world that your CPU can't run at full speed when it is fully loaded as long as the temperature is OK. The DTS column in ThrottleStop shows you how far you are away from the throttling point that Intel has set.

Dell is throttling some laptops based on power consumption. You're lucky that this isn't a problem for the applications that you normally run.

 

unclewebb, thanks for the detailed post. These are certainly interesting discoveries. I know when i purchase something I expect all the hardware to run at the full specifications given. Power throttling is very concerning.

Can you or anyone go into why there is no throttling on battery? Seems a little ill-logical that a little battery block can sustain better power output than a good size power brick drawing current from an outlet.

 

Well I currently don't do anything taxing, over the summer I was heavily multi-tasking between large projects in Photoshop CS4 (which is nicely accelerated by the ati 4670 btw!) and Premiere Pro with 1080p video. I never thought to monitor it then..It worked pretty well..I got the occasional hiccups when I was rendering a lot of filters on the 1080/24p content.

So at this point what do I do? Would you like the logfile? Do I call dell and complain? What can I do? Turn off EIST or anything in the bios? What actual part of the computer is telling the CPU to throttle? Is it software/bios? hardcoded into the motherboard? Because this is another issue that just adds to list, albeit a big one. This in tandem with how hot the laptop gets, is that enough for a return? Also my front of the screen, the plastic clear cover has never been set, the left corner pops out and it allows dust to get in behind it...this is frustrating..Anyway I could call/chat with a dell rep and swap for a 1647?....this is only 5 months old

 

tenknics: In most normal activities, this throttling doesn't seem like it's going to be an issue for you so I don't think you need to worry about it. Keep running RMClock and if you're ever working on something very demanding and want a second opinion, start up ThrottleStop and run a log file to see what it shows. At the moment, Dell isn't overly eager to admit that throttling is a problem on the XPS 1640 let alone fix it.

The throttling on the XPS 1645 is designed to keep the power adapter from trying to deliver more than its rated 90 watts. The XPS 1640 seems to do the same thing for the same reason. Anyone that is having a problem should look into getting a 130 watt adapter and running ThrottleStop or RMClock which will try to bypass any throttling.

peppe1: On battery power, the bios doesn't have to worry that you'll be exceeding the capabilities of the adapter because the adapter isn't plugged in. The result is less throttling. The XPS 1645 can still throttle when running on battery power. The XPS 1640 needs less power so it might not throttle at all on battery power.

Things could be worse. Some HP laptops have decided to lock the multiplier to a maximum of 7 when a Core i7-720 is on battery power for a total of 933 MHz. When running a single threaded task when plugged in, the multiplier can go as high as 21. 2800 MHz to 933 MHz on battery power is a pretty big performance hit that is not being adequately disclosed.

Product data sheets these days are not worth the paper they're written on. Lots of details are being left out so it's up to consumers to do their homework and do some thorough testing to find out what their new laptop is really capable of.

 

I'm just curious how they can size the battery and its power circuits to deliver 130w, 150w? whatever, but they don't pair up the same power capacity for the power brick.

I thought getting a bigger adapter would not help as the BIOS does not read the size of your adapter and still targets 90W usage?

 

On the XPS 1645, an adapter that can supply more than 90 watts will still be limited to 90 watts by the bios.

That's why ThrottleStop is needed. TS reverses the throttling as it happens which allows the computer to draw as much power as it needs. With a 130 or 150 watt adapter, it will be able to draw more than 90 watts and your computer will be allowed to run at full speed.

If you build a million computers and an accountant finds a way to save $5 on each one by using a 90 watt adapter instead of a 130 watt adapter then he probably got a Christmas bonus for being so smart.

 

Cool man, appreciate the time and info unclewebb. You're awesome

 

Quick question. I have an M1530 mini remote laying around without a battery. Will it be able to work on my SXPS 1640??

 

Without a battery, I highly doubt it will work with any notebook!

 

lol I know that, just before I go out and buy a battery just want to make sure that it'll work with the SXPS 1640. I rarely used it on the M1530 but now that I have a BD-R drive and a 1080p screen I'd like to put it to good use.

 

For those who have had throttling on there 1640 please post any information you have here:

I forgot how but I know its listed in this thread somewhere...How do you find your LCD panel id? Like the make/model?

Anyone remember?

 

I have a question regarding hard drives on the 1640. I whould like to know what HDD models come equiped on the 1640 @ 5400rpm (I ordered a refurb 1640 with P8700 and Ati 4670 and it has 320gb 5400 drive)

 

Hi guys,
New to this forum, had a 1640 for a while now, and slowly becoming unimpressed with the gaming performance, I have 10.3 drivers installed, but today I've seen comments about installing the desktop drivers using mobility modder? I'm on Win7 64bit, will the desktop drivers get me better FPS?

 

My configs are the same as you mentioned and my HD was a WDC WD3200BEVT (WD Scorpio Blue).

If you have it already go to Run... under Start Menu and type msinfo32.exe to find all your hardware info.

 

It should have free fall sensor and i think WD blue series doesent have one only scoprio black and thats 7.2k. Im still waiting for my baby probably i will get it in 2 3 days and i was wondering what HDD it will have with 5.4k and free fall sensor coz i have in my actual laptop a 320 scorpio blue and its pretty new and i will sell my actual laptop when my new one will come and dont know witch hdd I should keep

 

I installed a Seagate Momentus 500GB 7200 and use the WD 320GB 5400 in an external enclosure with eSata.

The 7200 is noticeably faster than the 5400 in every way, the only trade off is that it is slightly louder which but most ppl already know this.

I can't wait to get a SSD 256GB but this is good for now.

 

How do you find out the specs of the system from the codes you see when you enter the service tag on the dell site?

 

Try this link.

Service Tag on the Dell Site


Lol, I couldn't resist. Good luck man.

 

I think he was asking how to translate the internal dell part numbers and non-descriptive part descriptions into something intelligable, like system specs. Not how to check your configuration with a service tag (it seems he gets that far)...

 

This should be my cfg i can only belive what the seller says the specs are. I can understand only a few things.It whould be nice to know what kind of HDD i have, or check gpu and screen if there are as the seller says.O well i already bought it so if something is not how it should be ) i can only complain to the seller coz i doesent accept return.

Hope this helps.
Btw I was trying to help on my last post while maintaining a sense of humor so I hope your not offended blaze2k

 

The display is 16 or 15.6 ? Coz i remember i read something about some screens beeing 16 and some beeing 15.6 or only the RGB is 16" im confused. As for the HDD i know is 320 @ 5400 i think it also has fall sensor.Damn I bought it since 7 this month and is not yet here, its a long way from US to EU . Justice4all i see in your signature that it says 16 hope i have the same. How is 720p on 16inch? is now to low? Now i have 1280x800 on a 12.1 inch screen.

 

Yeah it's a 16 with a native display of 720p 1366×768 WLED. It is one of the first displays to come out on this laptop I believe. You don't see them as much now. It is too low but I hoped since it was a 16 it would run at 1920×1200 but no deal.

I thought even if the display was a 1366x768 native at least it will run games with higher settings since the native resolution is lower but unfortunately even with 130 watt power adapter, A14 BIOS, and a new motherboard and fan my laptop is still throttling just as much as it did from the start.

I can't imagine running any game at a native resolution of 1920x1200.
Good luck to you.

 

My xps 1640 arrived Is it normal the fan spins continuously? even when the laptop is in idle mode cpu temp 39C and gpu 52C

 

greetings,

Need a little help here. see my configuration below:

Studio XPS 1640 ( T9550 @ 2.66)
ATI MObility Radeon HD 4670
4Gigs of ram
RGB 1080P screen
256 SSD
Blu Ray burner
BIOS: A14
Windows 7
Dell 3 year warranty

Dell Just replaced my mother board,Heat sink, and Fan because of Excessive heating and throttling. also got my RGB 1080p panel replaced because the hinges were loose and my screen was popping out on the side. ( side note i read people were receiving WLED screens because dell said RGB were no longer being made - Bunch of BS mines just got replaced and its spanking new!)

I started using "speedfan" and "PC Wizard 2010" to monitor my cpu speeds and notice that both cores are running at 42 C which is 112 F! this can't be normal is it?
In the "pc Wizard" app i can see my ATI Mobility HD 4670 temperature at 47 C

any help much appreciated. should i call dell again?

 

42C isn't the coolest i've seen, but really, it isn't bad for a CPU. CPU's run HOT, and 112F is just a warm day in the desert. Typically, a CPU is too hot to touch!

 

Rebuilding mine; Windows 7 x64, and as the 'which drivers' section is out of date, hoping somebody who's recently updated their drivers can offer some advice.

So far, got these from the Dell site:

does anyone know if the studio xps 1640 can run without a heat sink? dell replace my mother board but sent the wrong heatsink.. i have the ati mobility 4650 1GB board and the heatsink was for the mobility 3650 512mb

i tried to boot it up but it immediately shuts down... dell will replace it but i really needed access to my machine tonight! any help would be much appreciated.

are there any senors that recognize no heatsink and shuts off?

PS.. i have a cooling pad to avoid damage to the processor...just need to access my machine for about 20mins or so.

 

there are no sensors that detect the presence of a heatsink, but, a CPU will go from cold to burning hot in a few seconds, and without a heatsink, there is nothing to cool it down.

I would NOT recommend running it without a heatsink. Is there no way to screw down the heatsink you have??

 

no...the heat sink i currently have is for a different mother board.. it fits perfectly over the GPU but the screws near the CPU doesnt Aline - so i just have half screwed on.

 

Time to give Dell another call.
