Sager (7280) Clevo (X7200) Power Supply Issues.

i just run Furmark mult-GPU and prime-95 12 threads on my desktop for comparison and my killowatt meter shows 1024 watts i am glad my psu don't shut down lol.

I did them both seperately with no issues. Why do we need to do this test? When will you ever use your machine in this way is regular use? There is nothing out there that will max your cpu and both GPUs as the same time, nothing except running 2 torture tests simultaneously.

We already know running both causes issues. My question is why does it matter?

 

Damn good question. Hey folks, if we don't do the sheer insanity that Speedy has done to his desktop to the Np7280, will the PSU still trip in other high load real world applications? This is in refference to OCed 980x and 480 Sli.

 

They do it for the plain ol' enjoyment of killin.

 

Lets say you play GTA-4 or Mafia-2 and both GPU's are max load then the game start using 3 cores of your CPU and maybe just maybe you have a program running in the background using one more core you may be surprised why the PSU cut off well that's why you run this kind of torching programs to see what to expect from your hardware and there will be no difference if you using a i7 950 still going to use the same watts.

 

Surprise, surprise, gaming is not everything You can find this earlier post of me a few pages back: http://forum.notebookreview.com/sag...x7200-power-supply-issues-36.html#post6820520

Both wPrime and prime69 use simple mathematics. What will happen when you start using more sophisticated mathematics?!... Imagine firing up Mathematica or Matlab and starting some computation or simulation @12 threads. Assume the best case scenario, 50% usage @12 cores. Given that you have in total 3 processing units (!), why wasting time and using only 1 of them, in fact, the slowest one of the three!? You want to be effective, for the given time you want to achieve max product. Time is money. So you fire up your CUDA-based nobel-prize-winning hydrodynamics algorithm that does not use so much cpu, but still some, and consuming all your CUDA cores and wanting for even more... Well, you end up with like 75% cpu usage @thread and all those poor little watt-hungry CUDA cores working the $hit out of themselves to make you happy. All that resulting in you being so fast out of the game that you won´t have time to make a complete blink... If you think that is unrealistic, then, my friend, you are being unrealistic.

This story kind of reminds me of all the people complaining how much less free RAM remains with Windows 7 compared to XP. Well, what the hell does anyone need free RAM for

BTW, I would not mind encoding the movie for tonight while playing SC2

 

Dear daykyu there exist something called research. A large of the research is done with the help of computer simulations. Personally I can see many situations where I would use everything. It is not happening very very often, but when it does it is critical. I would also like to point that taking into account the amount of money that I will pay for this computer, I think I should be able to use at full load for a few days from time to time.
There is more than just gaming .

 

OK. You have got me on why it is important to you. If you must have the 7200 and need to run 100% CPU and GPU at the same time your only option will be the SLI power, if indeed that is Clevo's solution.

For the other 99.99% of people that will use this machine it will not be an issue.

If you will provide me with scenario outside of a custom built scientific app that will cause an issue let me know and I will give it a test. This weekend I can try to write a blu ray while I game and let you know how it goes

Gaming is generally the most punishing thing most people do to their laptop. That is why I used it as an example.

 

Hmm, writing a blu-ray is not much of a stress. Can you encode HD? Gaming and HD encoding at the same time would be a nice and realistic test, realistic in so far that we will know if it is doable on that machine or not

Speedy already responded to the gaming part. That raises the question: why would the other 99.99% buy that laptop if they can´t or won´t utilize probably more than half of its power?!

Here is another scenario: Imagine trying to run Windows 2020. It won´t be able to even boot up, due to insufficiant PSU

 

Some just want all the power just because they can or to brag. Like me As long as this thing dosen't trip during Fallout NV or Starcraft 2 is cool with me. I think I will lean toward the dual 460s due to temps though.

 

with the cooling system as is the 480's dont get hot really, but the fan is freakin loaud at times.....

 

im willing to bet 470m sli provides more performance per watt at lower total consumption, and maybe, just maybe, even bigger overall performance, but i', streching it really with this one.

 

Maybe not overall performance but performance per watt is set to be higher than 480M at stock.

 

Hello,

I apologize for my aggressive post, sometime I get too much involved. I think that if I buy something I should not be restricted to use them only one by one. I am interested in having a hexacore with 1 480m card for work, but no overclock.
If you have some time please install the CUDA and CUDA SDK example and try some example from their (bandwith test, the monte carlo particles, ocean fft, smoke particles, maybe 2 or 3 in the same time). (If you have some basic programming knowledge in Visual C++ and CUDA you can edit the examples to put more particles and run longer. ) Thanks

 

Feel free to PM the details of the test that you want me to run and I will see if I can get to them this weekend. I am on the road again this week.

Preferably with some free technologies and data to try. Such as what video file to encode.

 

it could help if we put these tests in the "benchmark thread" so we can keep it all in one place.

 

Has anyone done any 3d animation with it? I use Maya on my desktop which maxes out my eight cores for hours at a time. Not sure how much gpu it uses while rending tho. But ill use it more for that than games so I want to make sure my four grand ain't wasted

 

Hi Speedy, that 1024 watts can't be real, can it. What power supply are you using with the x7200? From what I've seen it comes with a 300w supply.

Sorry if all of these have been asked before.

 

1024W was registered on his desktop

 

Ok, that makes more sence.

But what is the size of the x7200's power supply, I read some one talking about 600w, but that was probaly my misunderstanding again.

 

Its a 300w rated at 375w max. The 600 you heard about, might be a solution from Clevo adding an adapter that will combine 2 300w psu together.

 

World First! PSU SLi like some of buddies here said~

 

yeah that was on my desktop with 2 water loops 11 fans 2 gtx480 and overclocked 980X

you right i wish the X7200 could handle that amount of power lol.

 

Yeh that would be cool, uhm Hot uh yes....

 

And what's the cost of the cooling system?

 

Not cheap i spent the same amount i paid for two GTX 480"s on cooling

 

Damn.... so has anyone heard anything new about what sager is actually going to do about the psu?

 

Nothing new yet, but they are in testing right now. We are hopeful to be able to announce their resolution shortly for those who need more power.

 

I need more power"

 

Me too I have always agreed with Tim Allen...MORE POWER!

 

Just to let people know, mine has gone up to 400w and hasnt tripped, we still nedd ONE 500-600w psu clevo!... please

 

Wow! That's High and with one GPU and a 980x, if added another GPU you need 600 just in case

 

i forgot to mention the 400w is with an OC of 4ghz, maxed with prime, plus furmark

 

Just for you information, Clevo has a new motherboard for the X7200. I don't know if this was to solve the power problem.

 

lol, that would make me mad.. if that's the fix...

 

Hmm, where can we find more info on this?

 

Hmm.. For the good or the bad? They changed the Modded X58 Motherboard to? That would make me mad if they changed that :X

 

no doubt... i wouldn't put it past them though...

when the d900c came out.. the promised up and down that the 8800m's would be able to put in them fine... so people bought it.. then they needed a new mobo.. and the people whom bought it after the revision the d901c got the goods.

but who really knows.

 

Hmm, will do a check once it here on Saturday

 

i'm still waiting for mine... ugh!

it should have been here 7 days ago... but it looks like it **might** be here tomorrow...

the last update on UPS was :

THE ADDRESS IS IN A REMOTE AREA AND DELIVERIES ARE NOT MADE DAILY

so... i guess it must be close..

 

^--^
So you really do live "Somewhere in Time"

 

yup.. it would seem so..

same time.. last time.. this time.. yesterday.

 

You have to arrange a rescue mission immediately! looks like the delivery guy fell prey to cougars and grizzly bears. Their cubs must be OC'ing the beast as we speak, lol

And by the Zombie Vitzliputzly, switch to a different weed, hehe.

 

for sure! i'll give it one more day i think ups knows me by name now anyways.. I am of course... a Speed-Dial Assassin!

 

my UPS didn't even update since 29 Oct.

Edit: Updated Just left UPS to another UPS station, and the delivery time had changed to unknown*.
they better deliver on Saturday (6 Nov). After readin about UPS VS Fedex. my hope on UPS are back just néed to know hiw are they gonna charge the tax when my notebook reaches me.

 

I hope they didnt do something stupid with the motherboard. Mine is still being built. Anyone who hears anything concrete on this please post.

 

I just spoke with Sager about some issues I an having with my 7280 and asked if there was a new bios, an there response is that one will be out for supporting the 460 video cards. It seems as though everyone hears something different. lol
Anyone have any insight as to why I can't seem to hold an overclock when my system boots the second time?
I can tweak the system in XTU and it will reboot with the new settings the first time andrun everything stable Prime 95 etc. As soon as I power down or restart it either does the reset post to defaults or just loops and I have to remoce the darn CMOS battery. I narrowed it down to something memory related, and I think it isn't keeping my timings when I reboot the second time after changing with XTU. I tested this theory by lowering my multiplier to 18x at a 160 mhz host clock frequency, and it does the same thing. I'm running 1333 memory and an 950 CPU I've had it running prime 95 full stable at 4.2 ghz before rebooting. Any ideas?

Bueler.... Bueler?!

Thanks

 

At this time it is better you get no UPS Parcel !

 

No idea what you're trying to say here.

 

I had the same probs as you, OCíng with cpu multiplier only seems to be the only way to keep an OC and thats no good for your cpu is it

XTU neeeeeeds a setting which enables you to change the memory multiplier! We could then OC and keep the mem at the original frequency, as XTU does not like memory tampering.

What vcore were you at for your 4.2ghz OC? And what max amps and watt setting were you at?
