Asus Nvidia GTX 570 OC Questions

post #1 of 22
Thread Starter 
I just got my new card and I had some questions about over clocking it. I have been an ATI man for a long time and I decided to switch to Nvidia so I am not sure how the OCing works or if it works the same. I know for instance that I cant use MSI Afterburner which is what I used on my ATI Radeon 5850.

What is the max people are pushing this card to?

Is SmartDoctor the only way to OC it?

What voltage are you guys using with stock cooler?

Thanks.

Anyone have any insight on this please smile.gif

No, you can use one of a bazillion different software packages....including the Nvidia control panel (download Nvidia tools with ESA support). Afterburner will work just fine.

Not all software will let your over-volt it. Smartdoctor is "recommended", but you can use whatever you want.

Now the "what voltage are you using" is a tricky question with the GTX 570. "reference design" GTX 570's have a flaw in the voltage regulator design where they are prone to exploding when over-volting. Most manufacturers are aware of this, and fixed the reference design.

I have a Asus DCII GTX 570,....which is vastly improved from the reference design (judging by the fact you are talking about Asus Smartdoctor, i assume you have a Asus DCII too? ) I run it at 1.1V, 920 MHz core clock and 4344 MHz memory.

Alright thank you very much. Yes I have the same version as you.

Is your over clock stock cooling or do you use a different means to cool your gpu? I will try your values if this is stock.

I have another question....Does the Memory clock have a lot to do with how well the card runs games? I noticed that my new cards Mem clock is a lot faster than my old Asus Radeon 5850 but the Core clock is only like 30MHz faster.....Why is that? Especially considering how old the 5850 is compared to the much newer Nvidia gtx 570..... I had my 5850 over clocked to 930.

Also it says that this card only does 480 processes and my 5850 did like 1400....So confusing.

Download GPUTweak from the Asus ROG web site. It is an overclocking utility created by Asus for Asus cards, though it will support other GPUs. There is a lot more info on the link below...

Upping your memory speed will help in gaming, but too much will be unstable.

Asus DCii in stock form is only slightly overclocked but you should be able to improve that significantly. Part of the fun is finding how much you can improve it using GPUTweak...

So I gather you have an Asus dc ii gtx570. Good card I love mine. I like msi afterburner. You can safely keep cool the full 1125mv voltage allowed with 50% fan speed. My ambient temps are usually in the 70'sF and Im in the mid to high 50C range, sometimes when its hotter indoors it might hit 62c which is still WAY below max temps.

Second, great cards will peak in the 950-1000mhz range, seems like average overclock is in the 830-875mhz range. Mine isnt a golden gpu but does 900mhz at 1125mv, sometimes I will run it at 850mhz and 1088mv. You might need less voltage for the same overclock or more. I normally try an overclock by running the heaven 2.5 benchmark, once it finsihes I feel its time to try in a game, playing a game thats intense like bf3 if the best way to stress it. I personally use bf3 as my stress test and heaven as my pre-test.

Memory DOES help bigtime. I run mine at 2200mhz in msi afterburner (4400mhz in asus rog software). Try 2000mhz first, then 2100mhz, etc Seems like 2300mhz is the max most people can run, but I wouldnt go over 2200mhz just to be safe from messing it up. I think asus uses samsung memory which is supposed to be good.

Good luck

Wow thank you all for the great input....I will try this out.

Yeah, basically, i am in 100% with what 66racer said.

Yes, that's with the stock cooler.

The memory clock between Nvidia Cards and ATi cards are "in the same ballpark". Just some overclocking software shows you the value AFTER the multiplier and some shows BEFORE the multiplier (example 2200mhz in msi afterburner is 4400mhz in asus rog software). That probably explains the memory clock difference.
