The truth about the 7900 gs for 7800 Heat defect exchange

post #1 of 19
Thread Starter 
First off I would like to say calling Dell Tech support can be a real stress machine. First off the calls are routed all over the world. If you get disconnected and call back you will likely get someone in a completely different country. The most important tool in this is your case number. Take your case number and love it, learn it, and use it to your advantage as you will be likely giving this to anyone you contact.

Before I finally got someone to really help me I probaly went through 8 different techs and thier supervisors. I have the crappy basic warranty and told them I could not send my machine to the depot. I also told them I have my own business and am a certified(a+, MCSA, N+) Technician.

To be honest, my 7800 ran ok sometimes. But when playing games it often would hit the (93C) mark and slow the core down. I would have to go to the desktop for a few minutes to cool it down and then go back to the game. On idle, it ran 70c-80c continually going in this loop. My main concern is the life of the card. With this kind of temperature the card will have a significally shorter life span and this bothered me the most.

From the very start, dell knew the card had a heat problem. This is why the card was very underclocked to 250/550 instead of the recommended 350/850(these numbers are estimates).

Tired and weary I stayed on hold with Dell about 10+ hours on the phone holding while each one talked to thier supervisor. I would often be told they would call me back or get disconnected while on hold. Luckily, on one of my calls I got A woman that spoke significantly better english than most of them. She looked at my case number and created a dispatch for a new heatsink, fans and the 7900 gs Immediately. I was very suprised as most had to get thier supervisor. It arrived in 1 day of the dispatch.

This is not a guide or anything. I am sharing my personal experience in this matter. The fact is the 7800 DOES have a defect and was put on engineering hold. This information is in Dells database and they are aware of it.

The biggest problem is getting it shiped to you. I recommend if you have a defected 7800 send it in to the depot and it might save you many many hours and headaches.

Good luck to all that have this issue.

Not exactly. Most of the graphics cards in notebooks come underclocked. For example, 6800 Go comes underclocked out of box also (don't remember exact clock speeds), but it runs totally fine without any heat problems when overclocked. I am running it at 370/780 and highest temp i saw was ~65C (fans on high).

Finally got my 7900 gs installed. There had to be 100 screws in this laptop. They are very small and seated deep. I stripped one of the screws on my 7800 and I thought i would never get it out lol.

My 7900 gs runs at high 30's low 40's when idel using I8kfangui.(Btw 18kfangui is configured for dual core and runs great). I played a session of EQ2 for awile and the hottest it got was high 40s low 50s. There is a huge difference in the heat now. I can finally play games and dvds without going to the desktop every 15 mins looking at my temps.

This is just my first impression. Over the next couple of weeks ill post temps and such I get on multiple games.

Probably just the vanilla, my 7800 GTX doesnt run hot at all, quite a bit cooler than the 6800 ultra did, even heavily overclocked it usually runs in the 90s C, again heavily overclocked, stock I dont think it ever got above 80 for me.

Good threa, glad to hear you've gotten a new card

well said, and very true. Dell's tech support is a nightmare and one just has to hope and pray that you get a rep who knows what they are doing and willing to help. All to often if the tech is out of their league, you get put on forget then "oops" disconnected that one :P
Yes the 7800 Vanilla was put on an engineering hold, and Nvidia had a manufacturing issue to boot, thus the 2 versions of the 7800 vanilla, and the rev 2 wasn't any better.
I have begun to have throttling and even occasional artifacting (even at stock speeds, I rolled back my overclocks because of heat problems) and am pondering calling Dell on it...who knows, for now I can live with it, I can turn down my eye candy on Fear, and when I get the time and paitence to frustrate myself with tech support I might go there, unless I manage to wrangle myself a 7900gtx first
and +rep for you!

Hey guys, I am out of the country right, but when I get back to the US. I will try to exchange my overheating 7800 for a 7900GS. I have talked to Dell before I leave, but I ran out of time. My main question is, what is the difference between 7900GS dual heat pipes and 7900GS single heat pipe? I would like to know the speed for those cards, tempature, and the price for those cards and anything elese you all would like to add. Will Dell let me pay the difference for the dual heat pipes one? Thanks in advanace

I posted in that same thread and someone gave me a negative rep as well. I posted a link on how to work thru the DELL system to get a overheating 7800 replaced. I've made close to 500 posts, all taking quite a bit of my time to write up, hunt down links for people... all in the spirit of "helping" people. Each of my "reps" being EARNED from people who thought the info I posted was of help. Then someone comes along giving me like 6 neg reps... all within 2 minutes in one thread I had posted in. http://www.notebookforums.com/post2222448-19.html In that thread one poster who appears to be a regular poster in the "Reputation Points Thread" made this statement:

Notice where he said he "used" them to "have" a new computer (to use) while he was "waiting" on DELL to have just the right options on another model. Him "using" the computer for 6 months, then returning it, getting his money back and then buying the "DELL" he was waiting on. Asked if he was having "problems" with the unit, if there was a REASON for returning the unit... and then all the sudden my reps went from green to red. http://www.notebookforums.com/post2222448-19.html That's not right. Didn't receive a PM from him, nor was the negative rep "signed". I noticed the same gentlemen in the "Rep" thread says to sig your postive reps, so people can rep you back. Could be wrong about this person neg repping me, but the neg reps started right AFTER I asked about the above. Regardless it's not right to "use" something for six months, then take it back getting your money back to buy something else unless the item was having problems and the mfg was jerking you around. * * * * * * If I was a mod (and I have been asked to be a mod on some boards) I'd close down those "Reputation Points Threads" that are ongoing here. (Note: I'm all for a thread for chit-chat, but in those types of threads giving "reps" should be restricted to posts in which some tech info is offered.) * * * * * Here's how the so called "reputation system works. Note for the record the "reps" being "given" aren't EARNED for tech info, or advice in about 99.99% of the reps given. Note these guys are giving each other 10 reps per day amongst themsleves, over and over again artificially inflating their "reps.

Remember to sign the rep you give so people know to hit you back. You can give ten rep per day (24 hour period) and the amount of points you give per each shot depends on your own rep level (meaning the higher your reputation is, the more your rep is worth to others). If you have under 100 posts or have negative reputation then whatever rep you give (positive or negative) will show up as grey and not count as anything. In general it's best to stick with giving rep to those who have a similar number of dots as yourself, and then work your way up to the big boys. To check your own rep level click on UserCP in the upper nav bar, it will show you the rep you've received, when it was given, for what post it was given, and a comment if the giver left you any. Your total points will be above the comments section...
Excuse me if I'm wrong, but isn't the giving of "rep" points supposed to be for when you make a post in which others find the info useful (Or very, very bad- a post with profanity in it for example) instead of posts within 1 or two threads in which the persons aren't posting any useful info for the most part, but are instead just "repping" people back and forth... artificially inflating their "reps"?... Right now that (1) "rep" thread is running at 2081 pages, with 40 posts per page! Another thing, when you give someone a "negative" rep... you're only supposed to do that (1) time, not 6 times within 2 minutes. According to the above, someone who is posting in the "Reputation Points Thread" would have an unfair advantage over someone like me who in EACH post trys to help people, providing info, links to links that may help them. * * * * * Sorry for getting "off-topic but it's NOT right that someone should give you a negative rep for linking to info on how to get a overheating GPU replaced. I would advise people to archive that thread, because it does detail how to get thru the many hours on hold, the multiple phone calls you usually have to go thru with any big company to get anything done. Look at that thread with the mindset YOU have a overheating GPU, OR that YOU are having some other kind of hardware problem and YOU've been unable to get any action on it. Look beyond the people that may use the info to get a un-needed replacement. My guess is the people that are negative repping people for linking to, or commenting on the how to get your 7800 swapped out to a 7900 are the people who paid big bucks for a 7900 and are bent out of shape about that.

I am in the exact same boat, stupid game like Wow starts slowing down like my cpu cycles or something is being taken up, alt tab out, boom, video was throttling. between 77 and 86 degrees and in the game hovering around 92-93 degrees. I sent it back. 50/50 chance to see a 7900 come back, I hope. They said they were going to. Should see by the 22nd.

Took me two chat sessions to get a whole new replacement system with the7900gs.. I think there are no 7800s in stock any longer.

They have plenty of "refurbed" 7800 Rev1 cards

update

Its been a little over a week now that I have owned the 7900 GS Dell sent me and I thought I would share my experience with it.

First off, the heat Problem was Toned down alot with the 7900 GS. I'm shure this is probaly due to the smaller die size and better construction of the card. Image quality with the 7900 GS blows the 7800 away. Imediately when I booted into windows the text and images were alot sharper, especially in games.

As far as performance the 7900 GS scores alot higher and is a better overclocker, again, due to the smaller die size. In games I did not see a huge improvement, but there was definatley an overall improvement in the cards functionality.

I would say if you have a 7800 now and its one of the few that dont overheat to artifact lvl stick with it. Although the 3d mark score is higher by alot when you overclock the 7900 gs, the two are really close when you look at thier stock clock scores.(not dells underclocked 7800 score, the nvidia set scores) (7800= 5700@350/850 - 7900=6400@375/1000). I'd say the extra pipes and vertex shader help the most.

To wrap it up, I'd say im very happy with Dell and thier products. Even though it took me 2 weeks to get my exchange, in the end Dell will usually treat you right. Aside from the irritating customer servive, since its outsorced, This is the best laptop I have ever owned, We are on the brink of a noteble year coming up for computers. Directx 10 and Vista will bring a whole new era in gaming products and hardware. I cant wait to see what Dell has in store for this next huge leap in computer technology.
