Urgent GT Owners and NOW GTS512mb..You really need to read this.................

:shakes: http://www.geforce9.com/index.php?news=133:shakes:

Well , I just picked up a GTS512mb which i cant open till Christmas > I hope the memory is better than GT or i will be taking it back for a SSC640mb until Febuary....This is getting sad on the whole New Card memory thing...also have seen people memory clock to 2200mhz and just fizzle out.....Whats worse is the memory unclocked, Has been failing right out of the box..


ADDED Monday December 17th ........I just found this .....EVGA Forums and GTS512mb same symtoms as GT!!!!!!,,slowly gets worse ...This is BullSh8t ...I am now affraid to open my New Chrismas Present in fear of a RMA!
http://www.evga.com/forums/tm.asp?m=...1&key=&#194277
Even though this guy lowered His system Clocks .....This is still not good News for a new line of cards only 1week Old!I dont care how fast the card is..this is begining to be 1too many RMA's


NOTE: If your card acts up right out of the box Pixels// Screwed up Graphics on Screen ? It can not be fixed!!!! I would Return it or RMA it ASAP!!!!...The problem will get worse the longer the card is used..

Dec17th
Im not saying all cards have this problem , but there are enuff out there to be a little concerned...I had to return my AlfaDog GT512 with Rev2Fan...It was a christmas gift for my brother...i reseached for two weeks before getting one because of the know GT problems popping up..It proudly say it lasted almost two days...We have decided to buy another GTS512mb and hope that it works normal...I will let you guys Know after Christmas. I really have never been worked up over a simple VideoCard untill now.


P.S The posted artical...I think has a language barrier..:D

hmmm bad translator....but yes i have seen this occurring for some people, others it seems to not affect. a lot of GT SC editions are having this problem, 2000+ mhz on the memory causes artifacts. Its wierd though i would have thought manufacturers would internally test the cards clocked to what they are selling the cards at. I wonder if it is a problem with the memory controller itself or the quimonda memory IC's? The G80 cards also use these IC's, but have no issues.

knowing nvidia's history with mem controllers, I would say that it is the weak link in this case aswell

Why do you always have to use such blatant text, and big bold italiac fonts?? Jesus christ. Every post you make. Well, not every post, but I remember a thread you made about gettinga avideo card, and EVERY post you made in there had huge bold fonts in italiac and crazy colors, and it was kind of annoying.

:shakes: Yeah ... I mean my 320 did 2300mhz with out an issue 24/7...It had SAMSUNG... So this has me curious... I will know real soon what a Evga GTS512mb has under the hood......I cant open till Christmas though:D I kinda regret canceling my 640SSC...:ROTF:



P.S You remember my post right....so it must be working.....I have also found threads on failed GTS512mb's now:shakes:

I bet the GTS has qimonda 1ns, just like the GT. :(

It Probaly does use the Qimonda too ...
From what ive read the the G92/G96 were to use same memory manufacture @DDR3 speed...maybe thats why the price is under $400.00 for a GTX kinda like card that dosnt oc on the memory well .think about it ...use cheaper memory and it cuts at least $50bucks off the price:shrug: Im being sacastic..

This new Gt/GTS card is suppose to be replacing a 320/640 line which in fact was 100% stable even oveclocked @2200mhz memory...
The new GT/GTS should have been able to do this with no problems. Ive only seen one post with 2200mhz memory on a GTS512mb and only a 24/7 best of 2100mhz stable on the GT. Thats is if they were lucky to overclock the memory that good..
How many have been sold and how many GT's have new revision heatsinks and how many are still failing...we dont know...I can add one more to the fail list though.I would rather of paid $50 more bucks for them to get it right the first time...
Seems like a lot of people have been trying to hide failures or deny them...online vendors had been erasing legit bad reviews from customers with failed cards...Forums have been banning people over this...Those of you that search numerouse threads im shure have read about the Bans...Its major crap when people get fud for telling the truth on a product everyone is praising..

For the most part i dont care about some failures...but this is more than just some...People spend money for working items that should not have be RMA'd ...
I just returned a revision2 AlfaDog the one with New Bigger Cooler thats suppose to be 100% problem free..After waiting three weeks for it to come in ,it failed in two days...This quit nicely happened while i was telling my brother how good the card is over his old 6800....He did like the XFX logo and stuff and the fact that people are getting great 3Dmark scores with GT's..I felt stupid right on the spot when crysis loading caused the screen to start breaking up...So i rebooted and it was in the boot up screen and windows...typical failed memory or shader ....Imagine a tech telling a customer to use a product with high praise and to have it fail right before thier eyes..NoSale.

The new GTS512 sitting under my XmasTree...should be free of defect...It should be...So far one out of the two cards ,was a waste of time .We will not buy another untill i open the GTS512 on Christmas Day..

If any one has to lower the cards clocks because of pixeling or corrupted screen its an issue. Just dont mess with it , RMA' or return for another. This will hopefully allow the manufacture to fix the situation that people say dosnt exist when it does!.
Just like the 7900's that were failing way back when . They had Bad Capacitors/failing fans ,i wont forget that one ..Took three different cards before i said screw it and picked up a 7950KO..that at least didnt have the issue..
Ive owned several good cards ....All Nvidia...I feel they may have rushed this series..I am still buying and expect to see some failed cards....i am somwhat amazed how people deny there is no problem at all!

Sounds like the 7900GT dealio. I almost bought a new GTS today too :( All the more reason to hold out til the new cards come out in a few months /crosses fingers

Maybe this is causing the problems:

It looks worse than just running the RAMs naked with little to no air flow.

where are all these problem cards? Anyone here actually have one die?

Alexio - are all of the cards reported for having this issue using that same heatsink?

My New Alfa died yesterday! It was picked up on Saturday! Crap happens..it was the 640mhz with rev2 Fan on it...i was shocked, trust me..Me and my brothe spent $745.00 for 1 AlfaDog and one GTS512mb EVGA...the Alfa dog failed. i reserched the GT's for two weeks straight before purchasing that fn thing!.

I like Nvidia , but there is something not right with some of these cards...Oh as you can see the cooler dosnt fit on all the memory either, the New Cooler fits the same way, ...

Ok below is a MaximumPc Link, yes there a very reputble site and they review product very well..The people who go into thier forum also posted Gt failures too. Users just want to know exactly what is going on including me..another forum has taken steps to ban two people for commenting on the problem,which it is real...If i rember correct it pertains to the revision 1 cards which ,led to the revision 2 fans, every one keept saying there wasnt a problem and some places just wanted to qiete the comsumer who spends money for a working part.! This is kinda long thread ..page 4/5 gets interesting..well the whole thing is....Although this donst turn me away from nvidia .It just has me asking why are they trying to hide deny the failures..As long as the company fixes the issues, i will keep buying. this thread is barely 1 1/2 months old... Its funny how people say there wernt problems and there still are problems..I know i returned one yesterday!

http://www.maximumpc.com/forums/view...d94a44e7ca8d1f

Note: I wish people would look too , I know im not the only one reseaching this...I never saw stuff like this with the First gen 8800's.. Drivers wernt the best / we had complaints of Bsod's. But not this crap. The 8600's didnt even get this bad. There based on the same stuff correct?

That's what I'd like to know too :shrug:

One thing that I'm certain about is that high frequency causes memory degration (or degration of the MC) on these cards. Another thing that I'm certain about is that current draw in an integrated cicuit like the memory or the MC (part of he GPU IC) increases +- linearly with frequency. I'm certain that an over current is damaging either the MC or memory ICs on these cards.

It's unlikely that the MC get's damaged in this situation as the temperature of the GPU has a great impact on current draw of this part and this temperature is very variable. Nvidia would have come across this issue and they would probably have fixed it before the release of these cards.

Seeing that it's most likely the RAM ICs failing on these cards we can conclude that the higher current going trough these devices is causing the issue. There are two other important factors that determine current draw in an IC: temperature and voltage. Voltage stays the same in this situation so temperature is the only other factor that's of importance here.

From what I've heard just a small increase in memory frequency can cause damage on these cards (DDR1800->DDR2000 is only +-11%). With sufficient cooling this will up the current draw by only +-11% as, pointed out earlier, cucrent going trough the device increases linearly with frequency. I don't believe an increase of just 11% can cause damage in a short periode of time. My conclusion is that the cooling device (thermal pads with a 'heatsink made of air' in the fan area :ROTF:) isn't sufficient at a higher frequency resultion in a more than linearly increase of working current in the device. I think that with PROPER cooling the ICs are unlikely to suffer permanent damage at any realistic frequency.

my Alpha Dog is only a week old, but no problems running 755/1810/2000 for 24/7 so far. Its watercooled though...

Thats good to hear...It was luck of the draw for me ....I am highly thinking of WB for the GTS512 ..im gonna test on Air first...I like these cards...The GT too , We just need more people testing them...There fast and they bench incredably nice...I can live with out High memory.....Stability is a another thing all together.

If these cards could manage to get 90+ band width .It would make my day:yepp: they memory and 256bit controler are holding it back...I did 94.5B/W with my 320 24/7..Makes all the differance with good memory....The GTS512 should of had 512bit bus---1gig should = 100+ B/W this would definatly run over a GTX at same band width...They needed to used 1gig to begin with @1800mhz..

Then i wouldnt have even looked into the stupid memory issue crap:yepp: ...I want to see aGT512 vs GT1gig...I know it makes a differance..In everything not just High Res..High Bandwidth helps the overall speed in Gaming !.

I think this thread should be moved to news for more exposure.

Thats it, 3870 for me!

Just did a little test (Crysis benchmark) on my EVGA 8800GT SC.
Up to 1000Mhz mem, everything is fine, no artifacts whatsoever.
Once above 1000Mhz (1003Mhz more precisely), I get instant artifacts and my system freezes.

I'm gonna let the mem run at it specs (950Mhz) and only push core and shaders.
Card is watercooled with EK block.

With good cooling, 1000+ on the memory isn't hard.

Did the EK waterblock make a difference for the card's overclock?

I have a 8800GTS 512mb and have ordered this block.

My GTS does 1065 on the mem w/o artifacts.

I wanted to point our news readers to a thread in our HardForums that specifically addresses rumors that there are mass amounts of defective 8800 GT video cards. Looks as if it all comes down to one new GT owner with his panties in a wad. We have seen nothing that points to not being able to buy any companies' GeForce 8800 GT with anything other than confidence.

If we find anything information that points to issues with the cards, you can count on seeing it posted here.

Thanks you! I have been saying this for quite some time. :up:

thats pretty much what i figured... There will be defective cards in ANY lineup. One person gets a bad one or even a bad few and everyone freaks out.

Yeah, I guess we should now start a thread like, "the 38xx-series from ATI is glitching and messing up, oh noes!"
http://www.hardforum.com/showthread.php?t=1249357

;)

But it's not like it's just one or two cards...I had the same issue with mine as have others here and elsewhere. To say that it's just one guy masterminding the whole thing is a gross misrepresentation of the whole situation.

I wonder if this eVGA 8800gts I just ordered is affected...

Your "BSODs and memory dumps" (http://www.xtremesystems.org/forums/...d.php?t=168319) just sounds like you were having hardware compatibility issues, nothing more.

now not to start or add to flase rampant gossip...my evga 88gts was giving arti's at stock mem speeds,downclocking did help.
one day later it got worse so....
back to newegg for rma cus i dont need a beat from the getgo card.
but one bad card out of a few 1000 is bound to happen
and not for nothing i had three of the first 79gt's at the time,all fine to this day so....crap happens

I would have to disagree, I like the STYLE, happy holidays

My GT has been happily running it's ram @1000MHz since the day the GTs launched. No problems with it here.

I think one problems with people having issues with artifacts is heat. IMO you don't want to have a cooler that uses the same heatsink to cool the core as you do the ram ICs, ex; the stock cooler. All it does is probably introduce more heat to the IC's. Since moving from the stock cooler, to ND-1, then to VF900, my card has gotten higher overclocks and is much more stable then w/ the coolers that share the heatsink w/ core and ram.

yea, this card truly shines under water :)

Ok guys and gals...If any has returned /RMA'd GT /GTS due to D.O.A/ pixeling / slowly dying after Heavy 3D use ..Please feel free to post give coment..If there is no such problem..this thread will be fizzeled out in a few weeks maybe less from people not posting failed cards or experiances:yepp: ..


I dont post to just have a post...
I post to help others as they help me...


I feel i have valid cause to be concerned and have read many post on the New Nvidia Cards ...GT256mb/GT512mb/GTS512mb..In which the memory has been failing and or other related problems . This on more than just some cards at stock clocks .Even putting the slightest Oc on the memory can make it a dead card..

The Shader and GPU can handle a Huge Oc in stock form....The memory on the other hand can not!..If you use a real good cooler or W/B the memory can still fail real easy even if it seems stable @2200mhz...Its obviousely not ment to go Over even 1900mhz let alone 2000mhz+ which is really sad...I dont know what cause it to fail if its heat build up or something other . This happens even with stock clocks....Seems no one can get to the bottom of it..No one wants to comment how many have the issue or if it 100% related to the memory....The best response so far from a near by retailor .." Wow another one " I coulda ouched the Kid upside the head..It was Like he already knew what the problem was before i told him....

I really did not want to move up from a GTS320 , a generation of Video card which i have never ,ever, seen this failure with including the 8600 line!...Theres a lot of us overclocking and you do not see this failure from any other CARDS period....ATI runs smooth as silk @2200mhz-2300mhz..

I only buy Nvidia for Gaming and I also use Ati cards for non gaming systems..No offense to ATi intended , Ati cards run my non gaming Pc's 100% reliable .Is there a problem with something...Yes! If there wasnt you wouldnt see people posting ,"oh recieved dead card," or "my card fizzled out @stock clocks should i RMA?", is this normal maybe...For the Volume of cards sold ? I would expect a certain amount to fail. Makes sense right?


I honestly believe we are seeing way too much of "My new GT/GTS has pixels or slowly died out/I guess i will have to RMA/return it!" I have already returned Failed cards,,friends included in the last couple of weeks.. Trust me, Id rather be typing on ,"How High my NEW GTS scores!". Instead ive been more concerned about the card being stressed to much while i game..Ive never ,ever, gone there with the old 8800 line up! I could torture those cards with insane volts high clocks and even throw em around some and they still benched like King.I mean ,come on NVIDIA that was even a first gen 8800. I even have a failed 8800GTS320 got zapped in a power outage,, im doing CPR on the 320 so i can torture it some more! Why because they are worth putting back together:up:

My whole reason for making this post is that people need to be aware of what some of these new cards are doing!

So, "Please", dont "DOWNCLOCK" the Stock Videocard . This wont make it stable if you by chance happen to recieve a bad one! Exchange or RMA the product....This way the manufacture can look it over and fix the Fricken problem! You will see lots of stable cards out there no matter what ,in regards of the volume sold . Other people incuding Me are getting cards replaced because of an issue people say dosn't Exist.

"If this was true ,people would not be posting slowly dying cards or dead cards or pixelated screens as much." Despite the volume of cards sold!
I know drivers can cause some graphical problems, this isnt just some graphical problem.


Note: Drivers are one thing but a card that works one day and slowly fizzles out the next ,is not the Driver! At first i thought it could be a driver issue ,after reading post after post of people installing and reinstalling drivers and having to send the card back makes me think other wise.The fact that once the card dies or has to be underclocked to work@stock settings, its as good as 100%DEAD.The first gen 8800 had driver issues and BSOD's but not this problem in which me and others are experiancing. For card reliability ,I wouldnt run memory at a HIgh Oc for long period of time.


P.s. I expect failed cards on a new line .I cant even find a memory issue with ATI/competitor ,they have Insane Overclocks . Why are cards dying or having bad memory instability with in days of running .No other lines of Nvidia do this not even the Old First Gen 8800's. The GT/GTScards are increadibly fast when you get a keeper. I just want better //working NEW VideoCards for YOU and Me .We are buying products that are "Praised #1" in the Gaming Industry. I do care about what i buy and how it performs out of the box!

Thank You All

!gOtVoltage!

Was tired when i typed this please excuse the mess!

Dude, what is the newegg part number to your card? I just ordered one myself from eVGA on NE.com and hopefully it's not the same one you did :)

hey G.S
the same one you put the link to.
i should have my new rma card by jan 7,and i might have messed up cus i'm stepping up my gts 640 to one also.

i think i just got one of the few bad cards,my 88gt is rock solid.
dont worry your card should be fine
