Asus ENGTX470 Overclocking troubles

Tavalin · 19 Nov 2010 at 17:06

Hi guys,

Hopefully some of you can help.

A few months back I ordered an Asus ENGTX 470 (stock clock, stock cooler) from OCUK. I'm having trouble getting a decent overclock from it. The stock voltage it came with is 1.037v and I've managed to get it to 700Mhz on that voltage using MSI Afterburner. I've also set up a custom fan profile to keep the card as cool as I can at full load. Running something like FurMark or OCCT I get a GPU temp of around 77C (still with stock cooler) so I know its not running too hot. However I can't seem to get it stable above that speed even if I give it the full 1.087v available in Afterburner. If I go above that speed, after a few minutes of the test my screen goes blank but the card's fan still whoosh round at full speed.

(Just to note, I haven't even started messing around with the memory clock on it)

Does anyone have any hints/tips/suggestions for squeezing a higher overclock from it? Could it be driver related? I'm currently using 260.99 at the moment.

Thanks

Hi, i have 2 of the original Asus gtx 470s, i found the stock voltage they came with a abit high so i lowered it for heat reasons etc and simply cause i found it not needed, both cards run rock solid stable even when 100% stressed, 708 core and 1415 shaders @ 0.950v, both my cards will go to 800 core 1600 shaders and around 2000 mem on around 1.070v, maby i got lucky with the cards, i sure deserve it paying £300 per card, looking at the current prices sometimes makes me wanna cry......the curse of being an early tech adopter i guess, i had not had a new comp for over 5 years though, so the thought of a new high end pc drove me to spend spend spend

, anyways back on topic, i hope that info helps abit.

U might want to flash u cards with the Asus 480 gtx bios that let's u up the voltage even more also I be able to get higher mem clocks

I've not found the Asus ones that great for OCing tbh.

what is your system full specs??????????

Tavalin · 19 Nov 2010 at 20:12

For reference, my specs should be in my sig

Sorry to go of topic, Rroff, have you clocked many different 470's? Thankfully my two gigabytes are happy enough at 751, though i did have to do some ghetto cooling mods.

Rroff · 19 Nov 2010 at 20:33

Clocked a few POV and Gigabyte ones, not actually clocked any Asus myself but not had much luck when trying to talk anyone through it.

EDIT: Thinking on it I could be being a little bias tho lol never had much time for Asus motherboards or GPUs so a couple of poor clockers kinda vindicated my view point.

setter · 19 Nov 2010 at 20:39

Were the gigabytes soc's or standard oc versions? Heres a glimpse of my shoestring (quite literally) budget cooling for the two cards.

Knicker elastic and bootlaces, not pretty but it works ok.

EDIT: Funny, asus would be the only board i would buy theese days, previous p5q deluxe was great, current p6t deluxe is fantastic, the only boards i had die were an msi s939 and an evga 680i sli, more dissapointed with evga's terrible customer support tbh.

Rroff · 19 Nov 2010 at 20:41

OC Version only - sadly not got to play with the SoC yet - should be able to get 800MHz comfortably without much extra voltage and around 830-840 on average at 1.087.

EDIT: I wouldn't go beyond 800MHz without good case airflow tho, the voltage needed and heat output tends to ramp up considerably once you get past there for a relatively small MHz gain.

setter · 19 Nov 2010 at 20:44

Aye, at 751 my two are flying, used to run games with 4 x aa, 8 x af, tried MOH with 32 x aa, no detectable hit on performance.

Rroff · 19 Nov 2010 at 20:45

Even at stock I find a lot of stuff is very playable with 64x4SS TRAA and it really does look nice... granted I'm playing at 1680x lol so might be pushing the framerate a bit more at 1920x.

setter · 19 Nov 2010 at 20:49

I may try 1680 x 1050, though i do prefer to run native res, but im still on a relatively old 60hz lcd, (benq fp241w), theres no monitors in the market at the minute that would make me change, very good all round screen.

Rroff · 19 Nov 2010 at 21:13

Yeah no point running non-native. I only use 1680x as I went for a 120Hz panel being an FPS gamer.

setter · 19 Nov 2010 at 21:20

Been looking at 120hz lcd's, tbh being TN panels, im kinda put off, my current monitor is used for blu ray watching, so good viewing angles are a plus point, something that has always put me off TN panels.

buttkinz · 19 Nov 2010 at 21:21

what sort of fan profile do you run rroff, having trouble setting one up in afterburner thats any good, got a nice evga one, vid of 0.962 and clocks really well up to around 840 2000, too loud tho for my liking!?!

setter · 19 Nov 2010 at 21:22

I run stock fan, auto speed with some ghetto cooling.

buttkinz · 19 Nov 2010 at 21:23

lol, might pop in a side fan tbh, might help the temps a bit

Rroff · 19 Nov 2010 at 21:28

I'm back on stock fan for now. My cooling is almost as ghetto as setter's but my fans are regulated through a jury rigged controller to try and keep 30C case temps lol.

setter · 19 Nov 2010 at 21:28

Knocked 6c of my load temps, 85 down to 79, (auto fan, cards clocked at 751mhz). Certainly not pretty but it works, also added another fan into my 3 remaining 5.25 bays, cost 99p for what i can only describe as "g string elastic" and 2 fans i had lying in a drawer.

EDIT:All fans are on a zalman 6 channel fan controller, 2 x 140mm intakes, 2 x 120mm exhausts, one 120mm ghetto intake and the bootlace gpu fan, all are 1500 rpm yate loons, not counting the 2 akasa vipers on my megahelims cooler, thankfully theyre powered via a pwm splitter. i7 @4ghz, idles at 35-32-35-32. All fans on low.
