GTX580: 1.025VID: 950/1900/2300: stock cooler: guaranteed?!?

[p3gaz_001]

I think he wrote "water".

i didn't saw it, btw i'm still waiting your 3dm vantage with ppu off, do you remembere? .... (hwup)

Temp on the GPU ?

Thats a bit hard to compare due to the auto fan speed profile, I've been running my voltage at 1.000 for some time already while using the reference EVGA SC speeds, (797core) and its pretty fine. Im not sure how much the 0.088v adds to the heat as well.

Probably gonna try 1.000 @ 850Mhz core next week, highest I tried to OC my card with at stock volts is 900Mhz Core, I dont know how to start or even check for memory stability so I didnt touch it.

ye i mean gpu temp on idle ....
u should try that 1.000v @ 850mhz, but make sure to rise up your mems ,
800\2000 850\2100 900\2200 --> 950mhz 2300 1ghz \2400

i have to try this too

Stock cooling? No hehe. Water. Max on water with open window 1006MHz.

wich waterblock are you using on your card ?

I also wonder why evga decided to give this card a stock 1.088v, i mean it runs perfectly fine at 1.000v and it OC's to 900Mhz core at stock VID.. maybe Im not stressing the card enough with games/3dmark11/heaven2.5 thats why I dont see it go unstable at 1.000v ?

don't know.... but for sure in my case if i try to run any 3d app at stock voltage (1.000) with 900mhz it crashes

i have pushed up my 580!

Depending on the time of day and ambient temp in my spot, its between 41 to 45c, looking at MSI ab now the lowest recorded core temp it went down was 41.

How do I exactly test for mem OCing as people said GDDR5 as ECC and will be a bit difficult to overclock and check for stability because it automatically downclocks or is 2400Mhz 100% achievable on most cards?

this are my vga temps.

to test memory stability , some people suggest to use OCCT, or better crysis bench tool with 50 loops or more, unigine heaven, & co ....

[Demo]

So how would I know if its stable, my performance along 50loops does not degrade coz from what I understand GDDR5 has ECC and auto downclock..

At 1.088 Ive been getting 40 as my min temps at 797core, so Im sure at 1.000 i can get about 37 as well. altho my ambient is pretty high since its summer in a tropical country!

:


2. 3DM11
- AIR + 6core CPU@4400MHz + SS on GPU@1080MHz. Score 77xx
- AIR + 6core CPU@default + SS on GPU@1080MHz. Score 77xx-7805

Nice runs there Cole

Do you have a pic of SS evap mounted on your 580?

There you go.

can use this bios with my asus gtx 580 dcii to unlock voltage ?
thax .

[Punisher!]

i didn't saw it, btw i'm still waiting your 3dm vantage with ppu off, do you remembere? .... (hwup)

I have trial version so just one run. As I said, in any case, that GPU score is not influenced at all by PPU, so just make comparisons on it.

[-R8-]

some help plz .

Guys with reference cards and water cooling - if you stick your finger on the back of the card (on the opposite side to the mosfets) is it hot when the card is under full load?

[donmarkoni]

Yeah, and gets much hotter with OC, of course. I use fan, just to be sure it lives long and prosper.

[Dumo]

'11 kinda fun too

So its watercooled but you have a fan strapped to the back or something?

Very nice!


**EDIT - what are you guys measuring for stock vgpu at the back of the cards? Is what you set in software what you get under load?

On stock volts doing 920 MHz core / 1840 MHz shader totally game/bench stable and have left mem at stock for now.

[donmarkoni]

No, not all the time, just when looking for the edge of stability, to keep secondary heating out of the way.

I haven't measured actual temperature, but by the touch of the fingers I guestimate it's around 70-75°C.

[=SOC= Admiral]

Holy Bleep thats a lot of screen shots but nice man.

[Asmola]

Damn i love this Asus DirectCu II GTX 580. 950MHz 1.125v 2250MHz mem 100% stable on any stress.
Here temps when stressed with Unigine Heaven 2.1. Fan-profile can be seen on left.



Only "minus" comes from stock fan-profila which is way too tame.

[Cookiesowns]

I don't have the SS to prove it, but I can run about 965/2200 on my 1.000VID EVGA vanilla GTX580 on AIR stock cooler @ 100%, at 1.1v Heaven stable. 925/2200 at 1.075v BFBC2 Multi 6hour+ stable at 70% locked fan, max temp 75c

[CryptiK]

Pushed things a bit more testing the card.

950c | 1900s | 2250m @ 1.125v




Stable at the above settings for over an hour in BFBC2 all settings maxed 1920x1200 32MSAA

mine, a little bit ...

how to unlock voltage on my card ?

[Demo]

I havent seen anyone else post a 1.088 stock VID card yet aside from my self, haha!

I fried the GPU folding for F@H and I dont find it reliable since some WU's only stress the GPU to a certain degree, like some WU's only push my GPU as high as 65c while other WU's can push it to 71.. Games on the other hand can easily make it hit 75c
