Your GTX 470 overclocks?

Recently bought my brother a MSI GTX 470 from the MM, not sure if its the twinfrozr II or not will find out though.

I was wondering, what you guys have managed on stock cooling? To give me somewhere to start.

Its a little more complicated than CPU clocking with the two/three different clocks so I'm a little confused :(

Is the memory clock a bit like RAM memory clocks where when you get to a certain speed you dont really see much of a benefit? I think core clocks are where its at right?
 
Ive had mine game stable at 800/1600/1674 on 1.012v, benched at 821/1642/1674 volts at 1.087, (max in afterburner). Never bothered with oc'ing the memory, though for daily use i run them at 750/1500/1674, stock voltage of 0.987.
 
Am I right in thinking stock is similar to: 607/1215/837? If so the card overclocks quite well then with the core clock being around 30% quicker? :o

Am I doing this right? lol
 
Mine are gigabyte factory oc cards, 630mhz core compared to the standard 607mhz. 750 is manageable for the vast majority ive seen on here using stock voltage.
 
Aye so the clocks right, I've been googling a lot on this and there seems to be some multiplier to do with the memory?
 
Memory overclocking has very small gains on the 470 unless your hitting extreme core clocks. The ones I've played with all hit 800MHz comfortably on around 1.04 on average and 820-840 with 1.087. I don't reccomend more than 800MHz on the reference cooler tho. With high end air or water cooling 900MHz @ 1.1v is attainable and I know a few people who have hit 950MHz, on extreme cooling i.e. LN2 1200MHz has been hit :D
 
Haha very nice!

From what I've read, the max afterburner lets the voltage goto is just shy of 1.1v which is hardcoded or something. So I'm happy with that.

So if I go for 800core clock then 1600/1600 on the other two.. would be about as good as it'd get for performance increases?
 
Cooling is the main problem on theese cards, i would love to run mine higher daily, but the standard air cooler is too loud. Aftermarket coolers arent an option either for me due to slot spacing, theyre great for single cards though. Saying that though, they cope very well with anything im playing at 750.
 
Going from 600core clock to 800, not doing it almost feels like you're short changing yourself.. that is a huge overclock right!?

I'm trying to understand at what point memory overclocks are needed on graphics cards.. the sweet spot with normal ram is 1300-1600 at the moment isnt it? Would it be sensible to assume the same for graphics cards.. so for example if I got my 5870 to 1300mhz memory, which I have.. then it'd be better to then start pushing the core?
 
Yeah 600-800MHz is a substantial overclock - to be honest tho unless your playing above 1920x theres very little reason to go above 750MHz - at this time most games they give more than playable framerates infact I often run mine at stock these days - only reason I use mine overclocked and in SLI mode is if I want to hold as close as 120fps for my 120Hz TFT as possible for multiplayer games. (tho there are 1-2 exceptions to that i.e. metro2033).

The VRAM speed required will vary from GPU core to core, i.e. the 5870 may be more bandwidth thirsty than the GTX470 (or it could be the other way around) but in most cases VRAM speed has very little impact - going all the way to 2GHz VRAM on my 470 I saw slightly less than 5% difference in performance overall and in most cases no difference at all.
 
What is the stock voltage of the cards your using guys, ive noticed that the gigabytes i have use a slightly higher stock voltage than a few other 470's ive seen. According to afterburner display, the min is 0.875, max is 0.987, which they show on screen during games.
 
Great thats basically what I was after knowing, we both actually play on 1680x1050 so I think 800 will just about do in that case! I've not owned an nvidia in forever and I'm waiting for him to logon. So would you say 800/1600/1600 would be ok and any more would be very little in terms of performance increase?

I've been tinkering with my 5870 and I've got it to 1000core/1300memory, just tried it with 1350memory and it crashed, not too bad on 1.3v aswell (safety zone is 1.35, I checked ;))

Not quite sure which way I ought to be pushing from here though, temps were 73c. Testing only comprising of one round of BF3 which I think is quite sufficient... gpu usage still 99.. this games pretty hungry.

Will be giving the gpu a pasting throughout the day for sustained tests. I wish they'd bring out a bf3 benchmark (on rails so its the same for everyone) :(
 
All the cards I've used have been one of either 0.987 or 0.975 not seen any (reference design/clock) cards using anything different.
 
I think it was someone on here with a pair of asus cards, the voltage was slightly lower than 0.987, could well have been 0.975.
 
What program are people using these days to test it? I'm not a believer in using furmark or proper stress testing as I'll never use it for that so generally game benches would be good, ones on rails so that everyone gets the same experience
 
Aye its just nice to see an actual % increase, its hard to replicate the same situation over and over in bf3 :(

Cant even record demos to reply them, thatd have been good!

My Msi reference card uses 0.8750 and when I OC it up to 876\1752\1674 it was 1.075v, has the Gelid Icy Vision on it, great cooler by the way.:)

I used the Heaven benchmark when I tested my Msi 470.:)
 
Cool man ty.

What voltage are people using for around the 800 mark? On full voltage the temps are around 90c and I think even though the card is spec'd for 105, that 90 is a little too high so I'm trying to play with it a little :)

and I understand now that the shader clock moves with the core clock :D
