9800GTX+ 65nm die?

[tw3akm@ster]

Hi

Can anyone help with this? Getting 65nm as die on my eVGA 9800GTX+. Should this not be a 55nm die? Added some screenshots to compare with my other 8800GT.

Using forceware 178.13...

It makes no difference (few watts idle and load between the 65nm and 55nm) the 128 SP is there, IIRC some of the earlier cards bios hasn't been correctly updated to reflect the die shrink, nothing to worry about the clocks and specs are correct.

GPU-Z doesn't know the die size. WiZZ answered this question .

It has 55nm die, but in GPU-Z it shows 65nm, Something to do with Nvidia not changing the GPU code that GPU-Z reads. So it thinks its a 9800GTX .

GPU-Z can't read whether the GPU is 55nm or 65nm.
The only way to confirm - if that is really needed - is to physically measure the die sizes.

Die sizes for both G92 and G92b are the same. Makes things worse.

B1 is the 55nm version, overlapping the A1 (65nm) version.

Thanks to all. But would a BIOS flash solve this issue?

 

[insider]

There is absolutely no difference, only a single digit cosmetic one, if it really bothers you that much you could contact eVGA and request the bios update if they have one.

I tried to register with eVGA but the card was already registered. Sent them a mail last week but no response.(And they claim that reply within 1 day...) Bought the card from Paulieg who bought it from MKmod. Trying to sort out things with Paulieg. See the screenshots below for the things that are really bugging me. Some sensor information are not available... Is this still a BIOS issue? Will try with eVGA again. Any more ideas guys?

No they are not, you are looking the picture wrong. Compare the red squares and there's the size difference. The outer square is the 65nm die edge, 55nm clue stuff just blocks it. You can see the 65nm glue stuff faintly around the bigger square.

This one shows the difference more clearly, IMO.

I get same sensor info only as well. Don't know if bios will help at all. I seem to have .01 earlier version

edit: how did you manage 43C idle? That shot is with 23,4C ambient and with AS5. Oh well, new cooler coming.

MKmods made a nice cut at the backpanel of the card. See picture. This made airflow better. Hmmm will try artic ceramic later on maybe to see if the temps get down by some degrees... Thx for the info. BTW anyone knows another app that can show gpu & sensor details other that gpu-z just to see if get the same readings?

Aah, that hole explains the big difference EVGA Precision shows temps too and yes it's the same as GPU-Z. But it's a nice simple program for overclocking and I like that it can show FPS and GPU temp ingame too.

Here's the reply from eVGA:

Answer:

Hi, Unfortunately since you were not the original purchaser the warranty would reside with them and cannot be transfered to you. Thank you, EVGA

Question:

Hi Mike/Chris

I bought this eVGA card on the 28th August from a seller on http://forums.techpowerup.com who bought it from another person. The card had been used only for 10hrs. Couldn't register the GFX card to get proper support. Also sent a message on http://www.evga.com/about/ContactUs/Default.asp last week explaining the issue and still waiting for a response... (seen somewhere that you replied within a day...)I have attached a few screenshots of the issues that are bugging me:

9800gtx+ is a 55nm die; showing 65nm
lack of sensor info compare to the 8800gt.

Asked for help on the forum and they said should contact you, eVGA for support for a BIOS update:

Card serial no and part no:
S/N: 8088732000300
P/N: 512-P3-N873-AR

Kindly help

Found this interesting link that sums it up.

http://www.hardwarezone.com/articles/view.php?cid=3&id=2707

Would a BIOS update solve this issue? None up till now from nvidia... If someone has the correct info using GPU-z please post pics so that we can check your BIOS version.

 

[largon]

No, no bios update can get GPU-Z to show "55nm". Data shown in process tech -field is coded in GPU-Z. And I doubt W1zzard would bother trying to discriminate the 55nm chips as it's not done already.

 

[stanhemi]

i have a xfx 9800gtx+ superclocked here and it the same thing as yours but i don't care.For the sensor same thing as your.

1.) You won't be able to register it, as it has already been registered by one of the previous owners, AND only the original owner is able to register it anyway. Even if you could register it, eVGA won't honor any warranty without a copy of the original invoice with YOUR name on it. If it has someone else's name on it(in this case the original owner's name) they won't honor the warranty.

2.) The missing sensor info is normal, and no you can't do anything to help the issue. UnWinder(the creator of Rivatuner) summed it up best: "The sonsors aren't on the 9800GTX PCB. You can display sensor info if the sensors don't exist." I don't know why nVidia put less sensors on the high end 9800GTX compared to the lower end cards, it seems stupid to me.

3.) The GPU is 55nm, but it will always show as 55nm. Nothing you can do with fix this issue either. When nVidia shrank the G92 core, they did not change the GPUID for the new core. So every program that read what core the card has, gets the same GPUID as the 65nm core. There is no way for software to tell which core you really have, the 55nm or 65nm.
