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

[Demo]

950mhz speed, is a speed that any 580 reference or not can manage, btw ... i still think that 1.170 for 950 is too much, when i was on stock cooling on my card, the max speed was 960/970 with 1.125 and 1.138, not with liquid cooling with the same voltage i can bench at 987/990 mhz, depending on the waterloop temp (got two loops! )

Dunno if my card can do 950 at 1.150v might test it soon and prove/disprove you hehe

eheheh i'll be here waiting 4 your screenshots

I don't think my stock Asus would get 950Mhz benchable with 1.150V. Everytime I tried, even with ambient temp. quite cold I got a freeze after about 30sec.. Never tried with more voltage BTW.

Anyway for daily use it needs 1.075V for 851-1702/1456 (I mean GPU-Tool artifact test rock solid).

Well my screenshots wont prove or disprove anything lol!

don't know why only here i see this 580 running those high voltage for "low" speed....

my card runs 860mhz with stock voltage , sound really great, hope to get another lucky 580 ....

wich vid does your gpu have?

1,012v

that's nice ...

I confirm the reply to topic question is: "not necessarily".

With stock cooler I cannot bench, even with fan @85%, neither @931-1862-4204Mhz. I launch 3DMark11, first test OK, in the middle of the second istant freeze, even with 1.175V. A very strange behaviour seeing that I see no artifacts on screen.

I'll try with ~1.2V.

[p3gaz_001]

be carefull, your vga is not liquid cooled (1.2v on air cooling isn't so safe)

The strange thing is that it doesn't do any artifacts at all, I have just tried also with GPU-Tool, but after a minute of stress testing it makes NVIDIA driver reset (as if it hasn't enough power but it do has).

[Paradoxxx]

I got my Vanilla EVGA GTX 580 yesterday it runs at a default voltage of 1.0125. I'm about to start the process of testing the overclocks, I would like to determine opinions based on tools used to test artifacts. I'm leaning towards using GPU-Tool however I noticed that it mixed up core and shader clock readings. How reliable is the auto "find max" function?

Based on the adjustments options available with the tools available to me it doesn't seem necessary to flash my BIOS. Is it absolutely necessary to flash my BIOS to attain higher OCs?

usually if driver reset is like the voltage is not enough, but some times it does the same when memory speed doesnt match with the gpu speed.

1.012vid is a good vid, you sould be able to get 950mhz with 1.138, this on stock cooling,but you have to try step by step, first of all push to the max your gpu with stock voltage,(vantage ppu on loops, 3dm011 loops, heaven 2.1/2.5 loops OCCT GPU/MEM tool .. & so on) when u found that,start rising up the gpu speed until you get the max speed with max voltage,with an eye on temps, but be sure to match gpu speed with a correct memory speed.

Thanks for the advice, I intend to determine my max settings on "stock" cooling before moving a waterblock.

What's qualified as safe max temps for 24/7 conditions?

[p3gaz_001]

hey don't worry!

900mhz on stock cooling for 24/7 use should be fine and safe ^^

temperatures with 900mhz and stock cooling shouldn't go beyond 55/60 C°

what do you mean with that?

Lol wut, 60c ??

Thats probably impossible unless we have the fan speed at 100% with 18c ambient.

Thus far 875/1750/2004 tested stable at stock voltages (1.0125) and fan at 65%. Stability was tested using a 1hr OCCT GPU Test at 1024*768, I'll continue to test its stability via 3dmark vantage

I'll start posting with screenshots when I achieve something noteworthy.

sure? O_o i i was getting those temps while i was on stock c. 900mhz with 1.025v and 70% fan ..... but i do not have no more screens to proove that, anyway ... temps are not a issue , remaining on 900mhz speed, with 1.025voltages , since is near to stock, but i'm talkin about Paradoxx and my vga, not yours, 1.088vid

that's nice, 875mhz with stock voltage isn't so far from my stock!



what's max voltage? 1.150v?

[p3gaz_001]

what do you mean with that?

like 950mhz and 2050/2100Ram, when it should be 950/ 2200/2250Ram this is what i mean.

[Demo]

Its more like the ambient temps that matter over 1.025v vs 1.088v, on my end theres barely any difference in temps from 1.000 to 1.088v at 850Mhz with a fixed 63% fan speed, I think its only 2c at best.

Using synthetic tests like 3dmark or heaven2.5 is not a clear indication of stability for my card as I can run 950Mhz @ 1.088v all day long and on the next day the first run would show a rendering glitch which happens so rare, so yeah I can say my card is stable at 1.088v @ 950Mhz core depending on what we are testing it at.

Yeah.

Ive said it before, low VID is not a guarantee of a high clocking card. Just what it needs for stock speed and a bit over. Scaling is always different, just like with CPU's. Some are low VID but stop scaling early, some are higher VID but scale right up.

Would be a good idea to move the general GTX580 discussion over to the GTX580 oveclocking thread. This thread was about 1.025 VID cards overclocking investigation and its well and truly way off topic and I think best left alone now unless someone has more VID vs clocks related info.

Here you are the impact of overclocking GDDR5 over 4200Mhz, impact near to zero:

And you are making assumption based on 850MHz GPU testing?

You should reevaluate your conclusions based on this:

P7358 --- GTX580@1000/2000 --- 980X@4610 --- Sector 5 2250@2000/7-7-7-20-1T --- R3E --- donmarkoni

LOL your delta is of 800Mhz, mine just 200Mhz and of course with less limitations (as in your hardware configuration) it counts more (even if only about 3% with a 20% increase).


Anyway, [OT] I want your DDR3 :madsaw: [/OT].
