Run it without Phyx just for curiosity.

i try it... the sam problem

This watercooled or still on air malik?

Sounds like ocp kicking in. Do the black screens happen at lower clockspeeds if you up the gpu volts? If not that probably rules out OCP as the issue.

My MSI was very similar - 783 on air and black/grey/pink screens under load. Maxes on water at 860. on air 783/1188mv tripped the screens, on water its over 860 @ 1137mv or higher.

Yeap, still on air. This happens when i want 750+ on gpu On stock clocks everything is ok. Normal is 0.950V

[PiLsY]

Yeah try upping the volts and see if the freeze happens sooner. If it does its over current protection, if not its something else.

Could also try dropping the memory overclock. Memory oc goes down drastically at 80c+ gpu temp on both my cards.

You have right, when i set:

1.087 V - first test in Vantage passed so that is about 1min.
1.2V ... 3-10sec. and black screen.

OCP seems really variable on the 470's.

The 480 you can pencil mod to sort it. Are the 470 mods on vrzone?

[TheHardCase]

Added a little juice.
Runs Great
PhysX = off

Hi Guys,

As the title states, They have no stock of the asus here in Hong Kong and the selling is offering to me an evga. Both cards are reference models.

Thanks for your help.

[Q56_Monster]

Yes hodgy, you can run different vendor's 480's in SLI

Thanks Mate!

Can you post a link from 480 pencil mod pls?

[Systemlord]

Can you post a link from 480 pencil mod pls?

Why would you want to do a pencil mod when you can just using AB to increase the voltage?

I know, but if I understand @PiLsY correctly there is OCP pencil mod for GTX480 (that I can't find it on the net). I know for this OCP mod for GTX480.
Actually I'm interesting if there is vmem pencil mod for 480 like this one for 470 here.

What does this mod do for you? OCP is an unknown to me, it must stand for something right? Wasn't OCP the company that made Robocop in the movie?

I have seen lot of instructions on how to get up to 1.21 vcore on gpu, but how is it possible to have more voltage?
In a post i read that with a particular version of msi ab it is possible ot get up to 1.5volt.
Is it possible without any hardmod or any bios update?

i quote myself again since nobody answered :p

[PiLsY]

OCP = over current protection.

My apologies I did indeed confuse the 470 vmem pencil mod with the 480 ocp mod. -1 cookie.

[Grinchy]

You have right, when i set:

1.087 V - first test in Vantage passed so that is about 1min.
1.2V ... 3-10sec. and black screen.

If you up the voltage applied to the gpu there is not more current flowing,but only more volts and since power is voltage*current more power(and more heat).So the assumption that more voltage should make the ocp kick in before is wrong. If a 1.21 your card crash sooner it is because when a card reach its limits increasing voltage beyond a certain point only worsen things. If there were an OPP (over power protection) then upping the voltage would make it kick in before but there is not such opp in gtx as far as i know so your symptoms don't show that the problekm comes from ocp but confirm that your card is a bad clocker.I'd avoid removing ocp on card.this protection is a saiour when there are current overloads

I got No OCP/No OVP BIOS for GTX480 from here somewhere @XS.
Also, CHL8266 No OCP Firmware. If anyone is interested PM me.
EDIT: Uploaded, so you can just DL: nVIDIA_GeForce_GTX480_NoOCP_NoOVP_BIOS.7z, CHL8266_No_OCP_Firmware.7z.

[rintamarotta]

This is running in my i3 540 @ 4ghz htpc.

GTX465 running as GTX470 with mild overclock, system pulling 488watts from wall (PSU Antec Earthwatts 500W-D Green continuous power).
think psu upgrade comes soon for this htpc.

And for 470 ?

[donmarkoni]

And for 470 ?

Sorry, no. I don't even remember who made it.

[Malik]

Sorry, no. I don't even remember who made it.

Ok

I'm testing now ( again :P ) second 470. Strange thing... when i install custom bios, i can't overwirte old one :/

PS. I don't understand this second card. Now i testing SLI... and the results is 840/1680/1950 on 1.087V and working WTF !?!??

Hi everyone,

I am going to buy 2 GTX 480s. I found two different brands. One is Gigabyte and other one is Asus. Price difference between them is 56 dollars for each. Gigabytes price is the lower one. Both are brand new. Are there anything specific with Gigabyte's product quality? I never used a Gigabyte product before. Should I buy Gigabyte or just go with the Asus?

if u buy a Gigabyte then u will earn 112$ thats all Buy gigabyte it will performe same as Asus!
