[Uni] nVidia 9800GTX overclking test (Air)

single card pre-test,

will finish dual-sli & tri-sli soon after.


9800GTX Spec：
vGPU=1.2v~1.21v idle, 1.26~1.27v load
vRam=2.0v

ambient=18c，GPU idle=35c，load=53c（100% fan speed）

overclking results summary：
1）Driver 174.20 might have some bug，3Dmark03 result 20% lower than normal，3Dmark05/06 ok.
2）heat same as 8800gts (better cooler but 0.02v vGPU higher)
3）GPU core overclking better (better PCB/PWM/Cooling)
4）vRam overclking better (0.8ns, better PCB/PWM)
5）perf_lvl same as 8800gts clk 2 clk. (only deafault clk higher)

Nibitor3.7a still can't read 9800series bios :(

Weak.

Nice work, though.

That's some quality info you provide there. Thanks!

Pretty good 06 score for 4GHz Wolfdale too. So it looks it will have a slight advantage over 8800GTS (of course won't change my fact that this 9800 series sucks still but at least it's something).

untill G100 coming out, there will be no "significant" improvment on Perf_lvl 'coz of all same design & structure.

How is it possible that you are not bonded to NDA of Nvidia?

Not bad result in 2k6 with Intel dual core


thnks for the first tests Victor ! :up:


regards

that is some massive overclock for stock!!!

It is?

My 8800GTS does nearly identically, other than slightly slower ram.

So in the green camp, 8800 GTX remains king?
this is terribly dissapointing

850 core clock.. is that its limit... or is there more!!!

Is this longest we've gone without a major GPU update in a long time?

naw, i think 8800GT was a pretty good update, and that was only about 4 months ago.

Major as completely new eh? Such as from 7 series to 8 series....9 series is just a tweaked 8 eh? Guess that happens when there is little to no competition.

I think its safe to assume he meant update that makes for true inarguable speed improvement, not just a price friendly refinement. Besides in that context the 8600GTS to 9600GT is the update to brag about.

China's NDAs usually end early. Failing that, It's a gift, purchased from an errant merchant, or the card's "Hot"

overclock descent atleast.....shader at 2166 is nice, but i would rather get an 8800GTS if i didnt have one already.

agreed

so its slightly faster than my 8800GTS G92 when OCed..
i still plan on using my step-up if the card comes out in time.
give me something to play with.

I'm surprised it can do 850 MHz with only 0.02v more than the G92 GTS. Ahh, must be because of better PCB/PWM/larger heatsink and slightly better quality chip. On the GTS, the voltage has to be increased by a full 0.1v before it can do 800 MHz.

Shaders at 2160Mhz is amazing, BUT

BUT...

BUT...

The memory still sucks man, big-time and there are still only 16 ROP's. We need a 100% better performing card for those DX10 Vista games, not just a 20% better card... and it's long over-due.

Not mine! 801Mhz stock volts. But shaders won't go higher than 1905 :down:

how much does a 8800gts (g92) do on 3d06? it seems they are very close

I have results in this thread
http://www.xtremesystems.org/forums/...d.php?t=177459
with my G92 running at 800/2000/1030 and a yorkfield running at 4Ghz

8800GTS G92 with a better PWM layout and a price premium? Mmm, the sweet, delicious smell of market stagnation.

thanks safan, most likely the 8800gts can't be beat for the price and almost the same performance

if they sell this 50 bucks more then 8800gts then it is worth buying
