Problems with mobile Nvidia GPU's???

But if the notebook design does not leave enough ventilation for the GPU to cool, then there could be some partial blame on the manufacture.


Really, I haven't seen any of these effects, as my 8400m GT is OC'd to 700/700, and runs at 75C under load. My 8800m GTS runs at around 65C under load.

 

This is what really sucks.. only way to tell if your card is defective is "time will tell"...

 

Well, sorda. Everyone is freaking out, it's not a big deal unless your card is already showing high/abnormal temps. If your card runs cool, there is little to worry about.

 

Exactly, if you aren't experiencing any problems right now then don't be concerned.

Remember to blow out your laptop's fans with compressed air so your laptop will run cooler too.

Good advice from Tim. By the way, after you guys made me realize my old "cooling solution" was actually blocking the vents, I put the DVD cases under my battery, and haven't seen it pass 64C under full load yet. Can't believe how cool this thing runs...

 

What kinda cop out is that?

Laptop mfrs have strigent thermal envelopes, and they request the IHVs to give them TDP figures. nV is stating that the problem is a Mfr one of "a weak die/packaging material" meaning that the TDP they provided/spec'ed isn't the one delivered due to this defect. Now sure the thermal design would be involved, but that's because they expected lower TDP numbers and therefore they were unable to keep up with the heat, and that would be a big problem over a longer period of time as heat would tend to build up if it's designed to dissipate 40W but has to instead handle 50W instead.

Being placed in lighter, slimer, notebooks with weaker cooling may have been unwise in retrospect, however if they expected them to generate less heat the notebook mfr can't be expected to take the blame for what is a chip level defect. It may be a TSMC fault if anything, but even then it's up to nV to test and bin their parts, what kind of quality control is that. It would be like not blaming ATi for the poor thermal & power properties of the HD2900XT, and simply saying, oh well TSMC 80nm HS sucked so it's not ATi's fault they couldn't reach their target 1Ghz.

 

^ That had to have been the most acronyms I have ever seen in one post.

 

Some day ask me to explain to you the architecture/math involved in the SIMD ALUs that make up the SPUs , TMUs & RBEs in ATi's VLIW & nV's SPA - VPUs/GPUs and then how they use their ROPs & MRTs differently for shader/hardware based AA resolve, and how that would benefit CF & SLi, especially when used in conjunction with an NVIO style output unit.

 

Haha... I wish I even had half a clue as to how to decipher that alien-gibberish!

 

Guys, nVidia has said that they have updated the drivers through manufacturers' websites - now Dell XPS M1330 has updated the drivers dated July 1st and also updated the BIOS... the new version A11 I believe is mostly to to with the fan controls...

 

Yeah, A11 keeps the fan constantly on

 

This update, will we need to download direct from Nvidia or will it come through our manufacturers update? Also, have these drivers been released? Just wondering because Vaio Update reports a video driver update however don't know if it's got anything to do with this.

 

I just found this on Fudzilla and thought I would share it because I have yet to read which gpu's Nvidia had admitted were faulty and maybe somebody else can make sense of this.

Instead of answering questions this just makes more for me because what is the 8500M series? I don't know of any 8500 notebook cards so maybe its a typo?

 

Hm, sounds like it COULD be the problem of the G1S (8600 ddr3)- mine hits 100c regularly along with every other owner of one, except the ones that have taken ridiculous measures to cool it down. Heck, even those people (removing lids, undervolting, replacing thermal paste PLUS a cooler) only have the temps down to the mid 80s.

 

While manufacturers do indeed have specs to qualify for, there are multiple ways to solve the issue.

With the pressure to be lighter and thinner, many of them opt for less passive and more active. Active requires power consumption, (more heat elsewhere) noise, and moving parts which require maintenance most laptops don't get. This isn't a bad thing, as a combination of active and passive are ideal, but many manufacturers are choosing less and less of the more foolproof passive methods. Note one of the best things about passive is that you have more control of where the heat spreads to...

Nvidia did NOT cop out. They admitted their fault but told the truth in the fact that they are not the only culprits. Nor did I say that Nvidia didn't play their part in this.

I suggest you look at all the culprits not just the one you want to fixate blame on.

Note in my case, Toshiba built a laptop around the GPU that removes heat so well that I never exceed 69C even while massively overclocked. A GPU with the "defect" nvidia is describing could very well exist in this laptop... but the manufacturer completely made it irrelevant.

 

Do you think it is the card, or more of the design of that particular laptop? Most M1530 owners (same GDDR3 8600M) generally experience temps in the low to mid 80's before any type of mods/coolers.

 

I didn't say nVidia was trying to cop out, it was your statement shifting the blame to the OEMs, which seems to be the unwitting party in this. Like I said if anything it is the two parties nV and their Fab partners who are at fault. I 'fixate' on those because they are the ones nVidia specifically speaks to, not some other party blaming them for designing around their expected TDP and not the actual far greater than spec'ed reality.

Which is fine, many laptops are over designed or designed with higher tolerance to allow for other more powerful or future options, however not all of them are, nor should they be required to if they calculated for a specific thermal envelope with normal tolerances allowing for a normal standard deviation from the mean of failure rates. But most people shouldn't be expected to allow for a TDP associated with a GF8800M when putting a GF8600 inside.

 

i got my xps m1530 with nvidia 8600m gt few days back ...i have the option of returning it back to dell within 21 days ...shd i do it and get some other laptop like the studio with ati gpu ...i have a 2 year waranty ....

 

Watch your temps, and don't freak out. If they seem abnormal, then something may be fishy. If they idle ~60, and load ~80, you are fine.

And GreatApe, I have to do it... what is TDP? (Hides behind keyboard shamefully wearing the 'Dunce' cap)

 

tdp is thermal design power...

 

Yep, exactly;
http://en.wikipedia.org/wiki/Thermal_Design_Power

It's provided for all GPUs & CPUs for both desktop and mobile solutions, so that appropriate cooling/design choices can be made for maximum utility and failure rates can be kept at an acceptable level.

If a bug in the Fab process cause the expected number to under represent actual, that would mean a higher than expected failure rate.


BTW, carthikv12, thought you'd get a kick out of what they're selling at my local drug store;
http://www.londondrugs.com/msib20/Flyer/jun_24_08_hitech/pdf/hitech_1.pdf

Does your local pharmacy sell CintiQs ?

 

The design of the system does have to do with it, but even then, one of the supposed advantages of GDDR3 over GDDR2 is that they are supposed to run cooler. I've seen some M1530 users say they hit high 80s as well. Other users with a 1520 or 1720 see GPU (GDDR2 8600) temps around 70-75. However, I can't recall what temps people with a Macbook Pro are getting, but it seems like the 8600's w/GDDR3 memory are getting much higher temperatures than those with the GDDR2 version.

 

Well they're usually clocked higher too.

Just like GDDR4 was supposed to give lower temps and lower power consumption, but most mfrs were running them in 1.8V mode and as fast as they could, leading to them being hot and power hungry, whereas running at 1.5V and the same speed as the GDDR3 leads to power savings and cooler temps.

Same with the 8600MGT with GDDR3 running them faster is of course going to lead to higher temps.

 

hahaha... nice! ape, you guys are so lucky to have cintiqs lying around at a pharmacy! I've actually put my cintiq dream on hold for now... My school was stressing on hand sketches... so I'l probably buy it later... hope it gets cheaper.

And what's the best way to apply the max load on the gpu to get a good idea of the max temp?

 

I thought i heard that it was only for older GPU's. I hope im not affected then. the HIGHEST my GPU has ever gotten was 81C ONCE after gaming for a couple hours in a warmer climate. Which isnt too bad last i checked. I just wonder why nVidia isnt releasing a list of effected models.

 

man..been playing gears of war..the game looks gorgeous on it...however with the T5550 (I assume this is the problem, cpu bottleneck or could it be gpu temp?), the game stutter once in a while and frame rate drop noticeably. and on a few occassion, the fame just froze..and i had to press power button to hard shut it down.....

I did not have any utility or program installed to monitor FPS nor tempt but i felt the left heat outlet, its hot but not burning....any idea what this might be?

 

It's not the CPU, it's the game. Unfortunately, you purchased what can now be called "Man's Worst PC Port of 2008". Gears of War was amazing on 360, but despicable on PC.

 

Yeah, that's too bad, because it's better IMO using a CintiQ because it allows you to combine freeform with computer features like cut/past , duplicate and manipulate which is better on the fly than scanning in hand sketched images IMO. I think they probably want you to master the basics first, but I find I'm better on the computer than on paper.

A few good tests are ATiTool's artifact tester and running 3Dmark in a loop.

Also an old favourite (loved it back in the day) is rthdribl which used to heat up GPUs pretty well it's geared towards XP but works on Vista.

And from nV's site, geoforms does a good job too but is also XP-centric;

ouch! seeing the GOW sticker on the pc, i was like wat the heck, went to buy the game... got a bad pc game.... nice... ha.......thanks though, thats a good angle I never thought of.

 

Its not your cpu. I have a t5500(1.6 ghz) and a MR x1700 with 64 bits and it ran perfectly on 800x600 @ medium with some on high.

If it stutters it might be your ram. I have 2 gb.

 

It's not his RAM Bubba, please stop giving misleading information. Everyone has pointed out countless times that GoW stutters with even 4Gb of RAM. It's just the game.

 

hmm got 4 GB ram in my 6860..doubt its the ram...oh well , lol, such is life. thanks for the input

GOW stutters with 8gb ram lol. you need to apply the fixes Mangus mentioned, use the search function in the forum.

 

temps on my g1s can get up to the low 90's after playing grid (a little higher than Bioshock), I wonder why we seem to have the highest...as apposed to other laptops with the 8600 gt...i've heard of a few m1530 peeps with high temps however.

 

You're not on your own. I get 92C max whilst playing World in Conflict. I think it is more of a thermal design issue to do with the case not having enough air passing through it. I used to get 105C, but it dropped drastically after I changed the thermal paste on the GPU.

 

Im not sure if this is related.. but could my gpu be affected by this?

All NVIDIA 8400M / 8600M chips faulty?

I guess the answer finally revealed itself!! read on!

http://www.engadget.com/2008/07/10/all-nvidia-8400m-8600m-chips-faulty/

 

Ow joy, my Geforce 9500M GS is based on the troublesome Geforce 8600M GT, so I guess that explains the 85-90c temp while gaming.

 

so is it safe to assume my 8800M GTS in the gateway FX 6860 is ok?

 

yes it should be

 

But is the 9500M GS an A2? You should check the revision with GPU-Z
