Crappiest 9800GTX ever ?

[BenchZowner]

I should'nt have used this title ( pretty much ruins the "surprise" ), but I guess it's better to use a appropriate title, than misleading people.

Anyways, I've just Vmodded some 9800GTXs... and I think ( once again ) I've found the worst 9800GTX on the planet ( I'm surely the right person to pick the worst overclocking hardware out there ).

Max benchable ( AquaMark 3 ) GPU Core clock frequency is... 864MHz @... hold on... hmm... 1.412V ( idle voltage )

Next step ( 879MHz ) looks unreachable... 1.425V = nope... 1.435V = nope... 1.460V = nope... 1.475V = nope... 1.5V = nope... 1.525V = nope...

Idle GPU temperature currently 116F/47C

hhhhmmm mine dide max 864mhz on box air with 1.3vgpu load , but not any higher with more voltage .
on Ln2 @ -44°C 1055mhz core easy with 1.38vgpu

Gonna give the "good" one a try later on.
The "good" one does 864MHz ( AquaMark 3, 3D Mark2001SE, 3D Mark03, 3D Mark05, 3D Mark06, 3D Mark Vantage ) at stock voltage & cooler.

[BenchZowner]

Sigh, my best 9800GTX max on stock cooling ( @ 100% + additional " 'cold air' feed" fan ) is 900MHz... that's 18MHz less than my 8800GTS at the same voltage
Hope they get over 1000MHz on LN2... if not... get some cover, there'll be some 9800GTX PCBs flying around :@

I cant get mine stable above 850... And it takes 1.500 LOAD to get it stable at 850.

I guess thats worse than yours... But mine is a 8800 GTS, same G92 core though.

44ºC Idle in 28º Ambients, 56ºC Load.

BZ keep buying all the crap, amybe that way i'll end up with something decent

[gOJDO]

If you don't like your "crappy" card send it to me. I'll be very happy with it although it'll be clocked at only 860MHz.

You say your going to use LN2. Where is the 9800GTX suppose to cold bug?

That's a sad story.
Most of them coldbug at around -50C.
Vince ( K|ngp|n ) is working with nVIDIA to fix those issues ( 9800GX2's also suffer from this ).
They've got a BIOS that fixes ( or drops the coldbug to a lower degree ) for the 9800GX2's but sadly it doesn't work on every card ( weird huh ? ).

So it's either controlled LN2, or dry ice without acetone.

Sounds like a strong single stage will be the ticket for me thanks for the info - good luck with your cards

[BenchZowner]

Thanks, good luck to you too.

P.S. Yeah a strong single stage looks like the ideal solution for the 9800GTXs for the time being.

Just reviving the thread for some LN2 run "notes" for the "good" 9800GTX.
I wanted to get "the feeling" of my new VGA unit from my dear friend Vince ( K|ngp|n ), so I took my best 9800GTX ( 900MHz on stock cooling, Vmodded of course ) and mounted the masterpiece a.k.a. K|ngp|n's Tek9 3.0
I left the rig to load windows and left it idling at desktop while "adjusting" ( lowering ) my GPU's temperature smoothly, to find out where it coldbugs.
The temperature probe was just touching the base of the pot ( haven't drilled it in yet ) [ without any paste, just the top of the probe touching the base ].
The coldbug struck at -53C.
So I was looking to keep the card under that temperature and as close to -52C as possible of course
I was in a rush, so I have done some crazy ( or foolish, or just xtremely crazy ) things:
1) No Vgpu monitoring ( just prep'd the card some secs before mounting the pot )
2) No special cooling for the hot hot mosfets, just a 120mm fan blowing towards them ( shouldn't be worried, but considering the fact that I could be pushing way too much voltage at a point, and the "low" temperature due to the coldbug )
3) Real fast and not good enough insulation ( didn't face a problem, but was way under my "standards" )
4) Bad QX9650 cooled by a Intel Q6600 box cooler [ low clocks ]
5) Low FSB & RAM freq ( my Striker II Extreme was giving me a hard time, failing at pre-tested FSBs & memory dividers/timings configurations )

Anyways, the card "performed" well I must say, I don't know if it can bench higher, but it did 1068MHz on the core for 3D Mark2001SE/03/05/06 [ the voltage should be within the following range, 1.4V < Voltage < 1.6V ], guess we'll find out soon.

As for the Tek9 3.0... needless to say, it's the very best pot I've ever used in my 3yrs of extreme cooling ( Dry Ice & LN2 ).
There was little to none temperature swing in idle & load, I was able to keep the card's temperature at a specific value easily.
The unit truly rocks.
Godlike Vince, godlike!
