Stable speeds for 570 GTX

[morbidman]

Hi, I would like to oc my Galaxy 570 GTX http://www.newegg.com/Product/Produc...-070-_-Product.

I haven't overclocked anything before. I have MSI afterburner (haven't tried the bundled software from Galaxy) and would like to know what kind of speeds I can expect form a card with a reference heatsink like this. Thanks!

It will depend on several factors. First of all, each chip is unique. Second, your ambient temperatures will affect overclocking. Third, how you have the fan profile setup within MSI afterburner will affect overclocking. Fourth, how well your case ventilates will affect overclocking.

First of all, you need to figure out what your baseline temperatures are for the card is when it's under load. Download 3dmark 2011 or run a demanding gaem benchmark like Crysis or Far Cry 2, while having afterburner run in the background. After 15-20 minutes, quit and check afterburner to see what the max temperatures reached got to. Check and make sure this is in line with how the card should perform. Next, pick a maximum fan speed you can tolerate when you are playing a game (setup a fan profile under the advanced options) to activate at around the max temperature your card reached BEFORE you started overclocking. You have some wiggle room here. If your ambient temps and case keep your card nice and cool, you can set the fan to kick up at a higher temp than what you observed. Just be smart about it.

Then do your overclocking. I have no experience with the gtx570 reference cooling cards so I can't tell you how well yours might overclock.

I have an EVGA Superclocked 570 and my stats are as such.

Core Voltage 1025
Core Clock 797
Shader Clock 1594
Memory Clock 1950

They said the 570 can't be overclocked as much as other cards, so I would consider this your high limit if your using stock cooling. My card is factory OC, so chances are it was vetted for OC prior to packaging. My guess is you can probably split the difference and be safe, but definitely go with small changes. Freestone-Group makes a great stress test tool that you can use after each change to make sure things are stable. Good luck!

Thanks guys. I looked and the heatsink for the superclocked 570 looks like the reference model. But, it's likely that they are cherry picked whereas, with my Galaxy probably is not. Ambient temp here is about 21 celsius. Then again, I haven't closed my case panel yet as I'm trying to see if I can move my hd to a less obstructive position for my fans. If I don't play Crysis or Far Cry 2, are they still valid benchmarks though? Reason being that I don't have either one of them on hand. Thanks again guys.

Not true. There is a 50+ page post on overclock net with highly overclocked 570's some over 1ghz on stock cooling. What has people saying the 570 cant overclock far is that a few 570's have failed after going over 1.2 volts or disabling over current protection. Anyways I say go for 850/2000 at 1.05 volts since you are new to overclocking. The stock coolers can handle that fine and it gets you around stock 580 performance. Mine has stock cooling and has been running at 940/2100 @1.1 volts since release almost 24/7 folding/gaming. Thats +200 core and +200 memory a pretty good overclock for stock cooling and with a 1%-1c fan profile my temps are idle 34c load 68c . Just dont go over 1.1. or disable OCP. You cant anyways unless you edit the bios.

I was able to get my ASUS GTX570 DCII stable at 800 core, and 4002 memory with only a SLIGHT voltage bump (.975)

I consider myself luck and i love this card, despite it being such a massive sized card. It's very quiet too!

Mine is higher WTF ?

Good for you. Now you're about at stock 570 performance maybe a little better. All they have to do is move a slider and their 570 would smoke you.

Thanks everyone. After I fix my BSOD problem (I think it's memory related) I will get right on this.
