The Fermi Thread - Part 3

[kaktus1907]

I see a lot of unhappy folk mostly ATi boys/nVidia haters. I've got the card and i can tell you it doesn't get that noisy unless you run Furmark (90C) but under normal load ie while playing games the cars usually hovers between 70-75C and the fan is defo a lot quieter than the 4870X2/5970 or even the 4890.

My reference card can do 825/2000 easy on stock cooling and vgpu without any extra fan blowing over it in my Cosmos S.

default 06 run at 825/2000.

well said.. can you try to run higher clocks(i heard it has 0.4 ns chips same as 5870s) for memories while gpu clocks stays stock speed ?

the card crashes at 875Mhz almost instantly in '06, at 850Mhz it crashes in the second test but it should do 835/840Mhz core. I haven't pushed the memory yet. I'll do that now.

What brand did you get?

nVidia reference board.

EDIT : Here's the stock untouched GTX480 BIOS. Nibitor doesn't seem to work but maybe someone can figure out the way to mod it.

Vantage default at 825/2000 with the highest recorded temps.

Nice! Cheers!

Another thing, can you post a screenshot of device manager showing which IRQ number your GTX 480 is using, like the one below:



I'm curious if finally NVIDIA programmed the driver to use Message-signaling interrupts instead of pin-based interrupts.

How'd you get a cpu score of 68,000+ in Vantage with a bloomfield at 4300?

PhysX Enabled on the GPU greatly boosts the CPU score in Vantage

That's what I thought but isn't it supposed to be run with it off so all are equal?

The Physics test is probably running on the GTX480 and that's an incredible boost.

So many times I prediced that GTX 480 would barely OC. That nVidia would have an impossible time reaching 750Mhz.

If so many people are getting 800Mhz+, perhaps 480SP and 700Mhz had more to do with limiting power consumption than yields.

If you had chips easily able to do 800Mhz, why else would you sell them at 700Mhz?

By using LN2 cooling on a GeForce GTX 480 video card he was able to take the core clock from 700MHz up to 1165MHz, which is an amazing 66% overclock! He then used an Intel Xeon E5640 processor at 4GHz and was able to score just shy of 30,000 3DMarks in the Performance test of 3DMark Vantage

Holy Smokes Batman. Can somebody do the math on how much current must be going through those 6 voltage regulation circuits!!?

Me thinks at whatever ungodly voltage Shamino used for 1165, "normal" 1200W-1500W PSU could be not enough for the system.

At stock voltage it seems LN2 alone gets 900Mhz on the core - ie cooling seems to be the main issue

i understand this is actually because tsmc isn't producing the chips properly the channels are too wide, see my post above yours. Bx cards will probably have higher stock clocks, but won't overclock as far.

No.
They would just go for all SPs and slightly lower clock then.

An unvoltmodded 800 MHz stable on air is quite nice for an Nvidia card, no doing that on a GTX285.

1165 MHz and 30K vantage under LN2 is also very nice, I'd like to see some more results with a overclocked CPU.
