**The Official Studio XPS 1645 Intel Core i7 "Owners Lounge"

Did you try turning down the saturation?

i now use an calibtation file from the other topic, this helps again those painfull red colors.
The ICC profile is not perfect but for now it is better than nothing...
(also with Firefox the profile works great, With IE i get headache after a while from the fluoresent colors )

 

I was seeing last night that the 1647 does have an option for an i7-620M (2 cores w/HT).

 

yea that happened to me a few times when I had it, and yea only way to clear it is to take the battery out for a few mins.. I think you should call dell for a panel replacement. its almost like the R and the G LEDs turned off. to get the Blue, and the Blue LEDs turned off to get the magenta.

 

I too had this problem. Some people don't mind the almost neon colored reds. I tried adjusting everything I could find, the problem is that the colors are correct on a photo, but when you go to non photo graphics its WAY off.

the only solution I could find was to return the XPS 16..

but that was my solution, as well as a few others about a month back

good luck

 

Did you try one of those icm color profile in the 1640 thread? It corrected most situation for me except very few animations and games.

I returned my 1645 as well due to throttling.

 

FWIW, the standard 1080p WLED display on the 1640 (and presumably the 1645) is an awesome LCD! Colors are excellent (IMHO), whites are white and bright, it's sharp, and it's waaay cheaper than the RGBLED.

As a matter of fact, I've decided to return my HP dv7t because compared to my 1640, performance is actually NOT as good, and the display on the dv7t is washed out and not as nice as the 1640. The display quality was the major contributing factor to me deciding to return the dv7t.

I love the WLED 1080p display on the 1640...It's definitely one of the better ones out there in the sea of crap LCD's!

 

Hi, my 1645 is on its way. I wanted to know from a current 1645 owner:
1. Does the 1645 throttle under light tasks (web surfing, office documents etc) I mean is it almost always at the 933Mhz/core?
2. Is the 1645 snappier in light everyday tasks (e.g. boot time/application launch/overall speed) compared to say a p8600 1640 with both having same video cards/HDD etc. I have a p8600 core 2 duo 1640 with ATI 4670. Should I expect an overall better experience with the throttled (assuming dell doesn't fix it) 1645. I don't do much gaming. Maybe some photoshop.

Thanks for help in advance.

 

Does anyone know if the Displayport and hdmi can be used at the same time to connect two monitors?

thanks

 

1. No. You need to be pushing the computer HARD daily tasks can't even hope to do that, during normal use (web surfing/IM/document editing) half my processor is asleep (Windows 7 parks at least 4 of my threads when not in use) The only time you'll see the throttling is when you're doing something CPU + GPU intensive or in some instances just very high CPU. While doing the things you mentioned all at once and then some I only see between 3~6% CPU usage.

2. I can't say for sure (I'm coming from a computer with a Celeron chip lmao) but I've used P series computers and it seems faster than them and there's no reason it shouldn't be. If your laptop is being throttled though it's probably performing worse than a P series.

 

ok thanks, but then again, the 1645 would only throttle if CPU + GPU is pushed hard, as you said, and then it would become slower than a P series......but before being trottled/pushed hard, it should be faster/snappier than a P-series system them...that's what I think.

 

Pretty much, if you don't play games on it or encode videos or something like that you'd probably never even notice the issue.

 

At least that's what DELL was hoping out of this: Never even notice the throttling.

 

how's the blu-ray playback? any lagging/stuttering?

 

I noticed that this weekend, also! Almost all the time, only thread 1,3,5,7 are doing anything. 2,4,6, and 8 are at zero. I thought it was a problem with my dv7t until I pushed it, or ran a bunch of OS stuff, then I saw the even numbered threads come alive! Interesting...

 

Has it been confirmed that the throttling goes away when using a 120w power supply?

 

The throttling does not go away when using the 130W by itself because the current bios throttles it back to 90W, however, if you use throttlestop along with the 130W AC adapter then you can unlock your laptop potential.
We are all hoping that dell release bios update that frees the bios 90w limit.

 

Does the BIOS in the 1645 show the AC adapter wattage like most Dell BIOS's do? If so, when you plug in a 130W adapter, it still shows a 90W adapter?

 

Yes It shows what ac adapter you are using. Some users reported that the bios didn't recognize the 130W. I, personally, tried the 130W and it showed just fine in the bios setup page.

 

None that I've seen. It's mostly a CPU-intensive thing or a GPU-intensive thing, depending on the GPU. IDK if the 4670 does Blu-ray decoding....

Blu's run great.

So, if the BIOS does show when a 130W adapter is installed, but still throttles, then what would a BIOS update fix?

 

What it does when it detects a higher wattage adapter?

 

My understanding is the bios treats a 130W adapter exactly the same as a 90W adapter, i.e it restricts power draw to 90W even on a 130W supply. We are all hoping/expecting/praying that Dell re rwite the code so that the bios will detect the extra power and reduce throttling accodingly....

 

Exactly. A 130W adapter will throttle itself to 90W because of the BIOS. It recognizes it is a 130W (AFAIK) in the BIOS, but as confirmed by Kill-A-Watt meters, it still only pulls ~90W.

That's the point for TS. It lets a higher-powered adapter actually pull whatever it needs.

 

The current Bios limits the power to 90W. Period. Whether you connect a 65W or 1000W adapter . It detects it fine but still limits the power draw to 90W. The current solution available today is TS. The best solution we are hoping for is a bios update that removes the 90W limit.

 

It's totally the subwoofer being on that side. If you put your chin on the keyboard when you turn off the right speaker, you can tell that it isn't running. There are no highs coming from that side, only lows. But when you are sitting back a couple feet, you can't really tell.

 

Does it throttle when not on AC? Also other manufacturer's with i7 I have seen ships with a much higher powered adapter. Why in the world would Dell think it is fine to ship a 90W power adapter when the chip alone draws 45W!

 

My theory is...Dell is dumb or cheap. Maybe both.

 

Like Fenikkusu said "they are being cheap". I personally think that they are trying to keep the price very competitive and surely it is. But what they did is crippling the whole thing.

 

Like daraj said, it's not the power adapter, really. Sure, it won't operate on 90W, but it won't operate on 130W either. So, while the PA is certainly not enough, throttling seems to be a problem with the BIOS and deliberate code to decrease the performance on the system when on AC power.

I understand that, on battery, the CPU operates normally.

 

Hi all

Just got my new Studio XPS 16 last night (specs in sig). Beautiful thing, isn't it?

I was extremely apprehensive about the throttling issue occurring on it. However, I couldn't resist Modern Warfare 2 on it just to check things out. Here's what happened.

1. On first run things worked fine for a while but then stuff got stuttery and audio garbled. I assumed this was the well known throttling issue.
2. I had to come back to my room from a friends (where we opened the laptop). I decided to give MW2 another go. And played it for about half an hour or so. Buttery smooth, no stuttering.
3. Played again today, perfectly fine.

Was playing at native res 1920x1080, 2xAA, shadows and depth of field on, getting an average of about 35-40FPS. As far as I can tell, it wouldn't be doing that if it was in fact throttling. By the way, I have the WLED screen, not RBGLED.

Thing is, Dell shipped my system with the old A01 BIOS. And things seem to be working alright for now. I suppose it does throttle at times, but works most of the time. Haven't tried WPrime and CoreTemp yet, but will to know exactly whats on.

So my question to y'all is
1. Should I stick with the A01 BIOS or upgrade to A03 immediately?
2. What's your experience with the default installed Dell OEM image? Recommend reinstalling? Not too much bloatware that I can see on the comp. Got rid of McAfee and stupid Facial Recognition.

UPDATE:
Tried Prime95. Also tried i7Turbo to see what happens to the multipliers. On MW2, the multiplier went upto 14. Not sure what to make of that, but no stuttering. Still can't decide. To update or to not update BIOS. Help people.

 

Hey if the A01 working fine then leave it. I would wait until the new bios is released and see if it indeed fixes throttling then decide to update it.
It has been reported that if you close the lid then open it things will get better as far as games and thats probably what happened in your case.

 

dude.. thats exactly wat i'm doing!!!!!

Hey ppl sorry for being idle for so many days.. had my medical exams.. so waz studying/.. i got my laptop on 7th jan (first EDD being in dec )..

AND I HAVE TO ADMIT THAT I'M THE MOST LUCKIEST PERSON ON THIS OWNERS LOUNGE TO SAY I SIMPLY LOVE THIS MACHINE!!!!!!!!!!

~NO THROTTLING ISSUES
~GAMES WORK LIKE A DREAM
~FRITZ 12 CRANKS UP WHENEVER I NEED IT!!
~MIND BLOWING RGBLED SCREEN.. NOT EVEN 1 DEAD PIXEL!!!!!!!!!!!!!!!!!!!
~NO HEATING ISSUES... CRANK THE CORE i7 720QM MAX FOR 3 HOURS IN FRITZ 12 ANALYSIS MODE.. AND THE KEYBOARD AND TRACKPAD ARE JUST FEELING WARM.. NOT HOT!!!!!!!!!!!!!!!!!!!!
~9 CELL BATTERY AND 90W CHARGER ARE DOING SUPERB!!!!!!!!!!
~INTEL WIFI LINK 5300 is MIDBLOWING!!!!!! upto 180% EXTRA RANGE compared to other wifi (Checked in college campus with the help of my classmates laptop)
~FACIAL RECOGNITION IS EXCELLENT.. first it 5-6 times took about 5 secs to login.. but NOW IT RECONIZES ME ALMOST INSTANTLY WITHIN 2 SECS!!!!!!!!!!!! all you have to do is poke your face in front of the camers and LO! BEHOLD! YOU ARE LOGGED IN!!!!!!!!!!!

The only Problem i had until now is a random Freeze in between playing NFS UNDERCOVER (Just once.. start it again and the baby works like dream once more!!)

THANK YOU DELLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL FOR THIS AMAZING PROBLEM FREE MACHINE!!!!!!!!!!!!!! IN LOVE WITH MY LAPTOP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

I was answering the other user with the A01, but it seems like you have the A01 with no problems? Can you confirm that you have the A01 bios ?

 

Forgive me if I sound rude, but I just simply don't believe you have no throttling issues at all. Perhaps you just don't notice it or aren't driving the system hard enough, but even Source based games throttle on this laptop with just a 90W supply.

The 90W charger doesn't provide enough power to the system and this has been proved mathematically by enough people on this forum.

 

Is it just me or does kaushikpai's post come off as one of those throwaway reviews from eBay?

EXCELLENT POSTER A++++++++++++ WILL USE CAPS AGAIN

 

lol, it's been said OVER and OVER again.

P95+Furmark+Full Brightness

on any spec'd XPS 1645 and you will either get CPU or GPU throttling. Simple as that.

The first person who does this and reports full CPU and GPU clocks will be the first person to not throttle. Haven't met them yet, but I'm dying to.

What's up with A01, I don't know. But know that I'm not sure how you can revert back to an old BIOS. Sure, the program makes a backup, but whether older BIOSes can be flashed on top of newer ones is still up in there. I guess someone could try. What is the directory again, where it makes the backup BIOS before flashing?

AppData, right?

~Ibrahim~

 

Try here for a fresh copy of A01

 

Sweet, thanks, I'll try it tonight.

 

and risk bricking you rig

 

Yeah I wouldn't try it...or want to have to explain that to tech support

Dell_TS: "What happened to your computer again?"
You: "I bricked it installing a BIOS"
Dell_TS: "The newest BIOS caused an issue for you?"
You: "No err... well I was trying to revert to A01"
Dell_TS: "You rendered your computer useless trying to rollback to an outdated BIOS?"
You: "Yes."

Me: lmao

 

What's wrong with rolling back? When an updated BIOS contains a manufacturer flaw, and your recourse is to revert back to an older, WORKING version, was is funny about that?

Not everything newer is better.

Here is a link to a Dell.com community forum thread about 1640 owners reverting (backrevving) their BIOS successfully due to a CDROM eject bug caused by a newer BIOS. Seems everything goes fine with them doing a backrev. I'm sure a 1645 would work find if a 1640 works.

 

I'm not saying newer is better. Just a problem that has been occurring with the Alienware computers, so I personally wouldn't risk it.

 

Personally not risking it is a bit different than "lmao" and poking fun and someone who takes the risk and tries (for the good of the forum community) and fails...

 

It wasn't meant to be taken so seriously.

 

You can disregard their posts..I had the A01 bios for three weeks and the laptop throttles with P95 and Furmark, forget full brightness.The only difference from Kaushiks laptop is mine is a WLED and even it still throttles.Get better performance on the battery though than when the adapter is plugged in.

 

Hi can anyone fix this problem I've been having. When I am connected to a wireless network it shows that I am not connected in the symbol on the right hand side of my start bar(the wifi bars with an x through it). I still have access to the internet and if I right click on the symbol it says that I am connected. Just the symbol showing that I am not is very annoying.

 

It happens on my EEEPC and on my gf hp laptop. Im assuming its win7 bug.

 

looked at the wrong thing

 

EDIT:
nvrmind

 

I appreciate the responses, guys. It's true...risking a laptop is pretty weighty, but the joke bit, right.

Anyways, none of that matters in reality! Long story short, my computer BSOD'd during the upgrade A01-A03 a few days ago (replacement for captured system). A jillion errors when it POST'd, but it booted. Reinstalled A03 (no BSOD this time!). Called Dell, they said sorry: we'll give you a new motherboard and a SSD, too.

So, a couple hours before the technician arrives, I will attempt to flash A01 on, so even if it flops, I'll be getting a new motherboard anyways. If it wrecks anything else....LOL. But I think I'm in a good position where someone else might not be later on.

Huh...thanks, Nizam. I'll still try it, though, lol, just to see.
