GTX 470 Overclock

Hello Hello,

I'm having trouble overclocking my PNY GTX 470.

Ive read reviews and seen on forums with many users hitting well above what i can seem to achieve.

All i can get is:

730 core
1460 Shaders
1700 Mem

Anything above this is artifact city.

Anyone got issues??

  1. What temps are you getting at those clocks?
  2. Stock cooling? What fan speeds etc?
  3. Cheers for the reply but managed to get it sorted now.

    Downloaded MSI Afterburner, unlocked the voltage and got a monster overclock.

    805core / 1610 shaders / 2000mem

    @ 1.087 volts max 77% fan doesnt go over 86*c

    Quite happy i must admit....Can DEFFINATELY squeeze more out if i was to hit 100% fan, but for the sake of an extra 5% i'd rather save my ears.
  4. Any chance of showing us screen shots ?
    Would be interested to see what stock voltage and max voltage available is ?
    If your doing that with that voltage it seems impressive.
    The 5 series , some people pump up to 1.3 volts in to those things, not always with good results.

    The overclocks of our card are 850 MHz core (11% overclock) and 1255 MHz Memory (11% overclock).

    I also tried using ASUS SmartDoctor to increase the GPU voltage. I reached 890 MHz at 1.15V, 940 at 1.20V, 970 at 1.25V, 965 at 1.30V and 970 at 1.35V which is the maximum in SmartDoctor. Please note that the voltages are listed as they are displayed in SmartDoctor - not actual measurements.
  5. I'll try get some screenshots up.

    AFAIK the voltage is maxxed @ 1.087 - or should i say 'limited to' in the bios?

    Ive seen posts of people pushin 900core 2100mem on water cooling.

    To be honest i found that raising the core didnt really do that much after 800MHz . Raising the mem 50mhz (would actually be 100MHz as its GDDR5)= roughly 1% increase in FPS. The performance was still rising steadily but stability issues stopped me past 2GHz.

    Aparently at these clocks ive got im on par with GTX480 looking at some reviews with similar clocks (actually mine are bit higher than most reviews)

    I think stock voltage is like 0.912 or something btw.


    The only thing that bothers me is that im still getting sub 30fps at points in Crysis:Warhead and Metro :(
  6. Very nice temps at that OC! How is fan noise, still reasonable?
  7. It seems i lied!

    Unigine benchmark jus freaked out on me.

    Got to 90*c and rebooted lol

    I think Kombustor only utilising 96% may have something to do with the 82*c

    Moving the core down to 800MHz seemed to sort out the prob, fan now hits 82%.

    Makes me wonder if it was the core holding back the overclock now not them mem, gonna try upping the mem again.


    got some nice results on ungine tho.

  8. As to noise....anything above 70% is pretty loud.

    @ 80% or above its quite intrusive and 100% sounds like someones got a hairdyer on haha.
  9. I've noted from testing, temps that Kornbuster is less demanding than any of the Furmark releases. The tesselaion in Heaven pushes your gpu more, of course I don't have dx 11 :)
  10. I've never tried Kombustor, I always just use Furmark.

    Maybe you can help me out bro, when I try to download MSI Afterburner 1.6.0 Beta 5 it says, "Do you want to save this file, or find a program online to open it?". What's the deal here?

    Thank you, Systemlord.

    I have done much research about higher quality bin GPU chips being used by the market leading manufacturers like EVGA and other top card makers, but I have read that PNY the low end manufacturers use low quality bin chips. How else do you explain the cheaper prices?

    Those are the settings I have (which still could prove useful). The spiking in the GPU usage is from me going into WoW and running around for a few minutes, then alt tabbing out. I know WoW is more CPU driven but GPU does play a huge factor in Cataclysm.

    Seems to be running OK. Haven't seen high temperatures yet and I'm using stock cooling. The only thing, after doing Mafia II benchmarks for about 30 minutes, Kombuster doesn't run at 400+ like it was doing, instead runs at ~100 and Furmark was running each test at 10 FPS whereas beforehand it was 20 FPS and immediately after I OC'd it, it was at like ~25 FPS.

    Dunno if I need a reboot or not but nothing shady has gone on from what I can tell and the card is performing as it should both stock and my OC settings.

    Edit: I would rather deal with the noise with stock cooling to be safe. I use Razer Megalodons anyways so I don't even hear it. I use a 550W PSU and the manufacturer of the card is Palit. Hope all this helps.
