give me some starting values for overlclocking my GTX 470

setter said:
Ive set mine at 751 on the core, 1502 on the shader, havent touched the memory yet, (stock 1674mhz), stock voltage. Is it not possible to unlink the core and shader speeds on the 400 series? Havent clocked a card since my old gtx 280 almost a year ago.:o

Hi, do you feel the 470 was a good upgrade from the 280??
 
My 280 died on me, got a 275 gtx as a replacement (pretty similair to the 280), then added a second 275 for sli, at stock the 470 is a little slower than the sli setup was, hence the overclocking on the 470, basically i wanted to try a DX11 card.
 
Ran the heaven benchmark, set the res at 1680x1050 as opposed to my native 1920x1200, card clocked at.

Core, 751
Shader, 1502
Memory, 1684

Max temp of 84c, auto fan speed.
1680x1050

Weird that GTX470 is almost the same as my extreme tessellation/32x TRAA score... granted I have a higher core and memory clock but it shouldn't make that much difference.

EDIT: Wonder if the 260 drivers are bad for heaven performance mine was on 258.96.

EDIT2: Even weirder maybe I'm CPU limited not getting much difference from running those settings either.

Does cpu speed make much difference, im currently running 4.0ghz, turbo enabled, 21x193 bclk, also added a run at 1920x1200 above.

EDIT: Using the 260.89 drivers.

Are you sure the 32xAA was on in the bench.

I have benched with my 920 at stock, it make little or no difference to the results, purely a GPU dependent bench.
 
Yeah 100% sure 32x AA was on... wondering if extreme tessellation was actually on tho even tho it says it was - as re-running it now seeing a bigger hit.

Getting new extreme tessellation and settings as above runs now.

EDIT: Yeah looks like extreme tessellation wasn't actually working even tho it says enabled - not sure why - re-running it now avg. is 31 not 41... thought at the time it seemed a bit high for 32x AA + extreme tessellation.

EDIT2: Get 44fps average at 800/1600/2000 with 4x AA, 4x AF, normal tessellation, 1680x.

Used nHancer - was def. running 32x AA as I double checked it was actually working because its tricky to get it working - its obviously the extreme tessellation that wasn't actually working as theres no way you'd get 40+fps on a GTX470 with that on with any level of AA.

Thanks for posting this up Rroff, gives me a ballpark figure. Bit higher than my own run with the same settings, 1920x1200 does drop mine a fair bit though.
 
My current settings seem to be pretty good in game, moh and mw2 feel a lot better compared to stock speed, even seems a bit better than my previous sli 275's, ill probably keep theese clocks for the time being, push higher when funds allow me to add a better cooler.

Hi sunshinewelly, seems strange you can't get past 700, what power supply are you using?

Hi think it was just me that couldn't get past 700 (sorry if that was bit of a thread high-jack but was a similar issue/topic) I'm using a coolermaster silent pro 700w psu - so i'm not initially enclined to think it's the PSU - think it has 50amps on single 12v rail. I've some other things to improve results, tried changing power management settings on windows and in nvidia control panel. I might try a different pcie slot later on and see if that makes any difference and also check that the power cables are all in place ok & re-arrange the airflow in the case a bit - core temps on the card don't seem to be the problem either as they're not going aboce 75-80 by the time it crashes - but could be something else that isn't temp monitored overheating.
