GPU crunching setup ?

TheDogFather · 6 Dec 2009 at 12:16

I know nothing about graphics cards, my previous card a Matrox G450 says it all.

Ive got a 9600gso running Seti. Following some advice in another thread, I've turned the shaders up using Riva, but I'm seeing talk of PhsX and 3d whatever, what's supposed to be set to what for best crunching performance ?

I already have it running, I downloaded the latest drivers and followed instructions in a thread here to get it going. Since then I've been snooping through some threads, this one in particular

http://forums.overclockers.co.uk/showthread.php?t=18043896

which made me wonder if anything (other than the sliders for overclocking the core, memory and shaders) needs adjusting from the default GPU settings to get the most from it.

I have no idea what they're talking about in that thread, but it gives me the impression they got a lot more points in 3d than 2d (whatever that is), so thought I'd ask.

Thanks loudbob

So looking at the tab in rivatuner where the sliders are for core/shader/mem theres a tick box 'enable driver level hardware overclocking' then a drop down, its default setting is 'Standard 2D' I should set this to 3D or I'm loosing out, anything else while I'm in there ?

I tried EVGA, now I'm confused as theres no mention of 2D or 3D anywhere I can find. I did try setting Riva the way I thought it might work, low clocks for 2D and high for 3D but don't seem to be able too, whatever I set one to affects the other. It may well be user error, or maybe some cards just run one speed for both 2D/3D ?

The card is the ASUS EN9600GSO Magic, it was in that thread months back, people were unsure if it had 96 shaders or not (it does).

edit/ I remember now Riva complaining about compatibility with the drivers, I need to roll back to a older version anyway so hopefully that solves that. So I do that set two sets of clocks for 2D and 3D and alls good (hopefully), I think I've got it.

I set them to 1650 just as a temp measure until I have time to look at it properly, it seems happy enough, all the wu that have had errors have also had errors for my wingmen.

So the other days outage saw my gpus sat idle and again this last 24 hours. I've tried the rebranding tool, it did nothing. What am I missing, why do I have lots of cpu wu's but no gpu ?

My cache is set to 3 days I think, maybe 4, but I seem to run out of gpu wu in hours.

edit/ Fixed, theres a button on the settings tab for Only VLar+VHar to CPU, I deselected that and it worked.

I read that as it would only move vlar and hlar from the gpu to the cpu, not what it actually means.

Its been a learning curve but I think I'm there now. (hope so anyway, I havn't got time for this).
