The ***OFFICIAL*** F@H Harassment and discussion thread!!!

[=[PULSAR]=]

Okay I'm trying to run a 3rd 9800GX@ but the 790FX I have it running on won't recognize it at all. I tried different bios, different drivers and nada. Does anyone think they can help me get this card running to help support the team

[Sparky]

Which board is it?

Please tell me what you did. I'm going through the same thing on my P6T. Fresh driver install only recognized 2 cards.

[Kingcarcas]

i dont trust giving away the use of my processor unless its by an official organization like red cross or something, otherwise hackers could be using it for all i know, and as we all know hackers are garbage and should be cleansed with fire.

and im sure everyone at sanford university has a heart of pure gold, im sure none of those people are hackers and such and i can trust giving them access to my computer which has vital personal information..sorry but your argument fails once again, id only have absolute faith in god to be all up in my pc like that, and thats how many others feel.

not to mention running a pc at 100% ALL THE TIME will burn it out in no time.. plan also fails the university has massive funding, if they wanna use part of my pc they can pay for the privilage, their sponsored by multi-millionaire's and such, they got way more money then me, so they can burn out their own cpu's

That's what i get for trying to convince this random guy at gamespot to run F@H.

Well actually my problem was with the motherboard tray. Since the tray only has one slot for that 3rd card it wasn't seeding correctly. I had to bend the backplate on the card to have it fit correctly and it recognized the card. I don't know about this setup though. After about 30 mins of folding the machine will just cut off. I'm thinking its a heating issue or the fact its a 900W PSU and drawing 860W is putting too much stress on it and killing it.

Thanks. Mine may be a different issue. I'll give 3 cards one more try. You may very well have a heat issue. Even with 2 cards and the Old Chap fan mod +, my 2 card setup is running 90-93C. No EUEs from this rig today though.

Just multi-metered my 12V rail and....11.84V I wonder if that has anything to do with it? Here is another question I have, does the link speed of the PCI bus have anything to do with point production?

[Lowrez]

No. Link speed has no effects even at 1x you would be fine.

[Sparky]

Your 12V rail sounds low if that is a DMM reading. What PSU is it again?

[=[PULSAR]=]

OCZ 900W ModXStream, I guess when I get my CorsairHX1000 back from RMA I could give that a shot and see if it is in fact a PSU issue. Right now I'm trying down clock everything else to help raise the 12V rail right now its back up to 11.92

AFAIK ATX convention is that the rail needs to stay within 5%, yours isn't even two percent off. But when you say 'cut off', is the whole thing shutting down? Then it still is a PSU issue IMO.

I'm also interested in that links speed question, did anyone confirm if pulling up PCIe from 100 to, say 115MHz, has any benefits?

[=[PULSAR]=]

Yes it just cuts off, like it wont freeze or lock up or anything like that. It will just straight click off and then I need to reset the PSU before I can turn it back on.

[p2501]

That really sounds like you're torturing your PSU atm.

[=[PULSAR]=]

Yea if it does it once more, its going back on the kill-a-watt and starting some voltage tuning. I'm using a 900W PSU whats the max constance usage? I find it wierd its a 900W PSU and I've drawn on upwards of 940W.

[Sparky]

900W output. But at say 80% efficiency it could really be pulling 1125W from the wall.

[=[PULSAR]=]

Okay well it seems down clocking the cpu and lowering the cpu and nb voltage got me stability. Overclocking the cards is limited with the shaders @ 1775mhz. The middle card in the sandwich keeps flashing unstable machine, pretty sure its due to temps currently showing 94C. Maybe I'll go to watercooling...you think a Thermochill PA 120.3 could cool all 3? Heres a SS of progess. Ever since I had this rig folding I had to completely turn off my heat my room is 27C.

[Sparky]

If you go water, grab some of those EK 9800 GX2 blocks on sale at performance-pcs. $40 off each one right now. Click >>> http://www.performance-pcs.com/catal...ducts_id=23628

The thermochill should do it I'd think, with moderate speed fans. I can't imagine it being any worse than stock air.

[=[PULSAR]=]

Hmmm spend $420 on blocks or put that money into a i7 build with a GTX295...dilemmas, dilemmas I might blow it on the blocks purely so I can sleep in peace without my noisy Ultra Kazes spinning. Lets see how much I can get back on my income tax.

[OldChap]

Instead of changing the psu has anyone thought of just adding one?...supplying one card with a separate psu

@wfo...what fan are you using?

[=[PULSAR]=]

I may I got a OCZ 400W in my MM case running dedicated for dual waterloops. My Lian Li has a slot for a PSU maybe I'll move it over.

I always wondered, doesn't a PSU get the signal from the mainboard via one of the wires in the 24-pin plug to wake up from standby? So how would the second PSU power up without that signal?

[=[PULSAR]=]

You take a piece of wire or a rocker switch and connect it from the green to a black(ground) connection on the 24-pin cable.

[Sparky]

Or, what you can also do is connect the green wire from PSU2 to the green wire of PSU1 so they power on and off together. That way you can't accidentally forget to turn the secondary on or off and potentially fry something.
