now a graphics card ?????????????

this would be nice but No way is it in my price book

What I'd do is get a little better RAM for that rig as not only are Conroes picky but you won't clock high. I'm not up in the DDR2 department though to help. Post in the Intel Memory section or read some recent C2D threads there. If you can get a 1900 you could fold on that.

[frozndevl]

Hell, if you've got rigs with room for the vid cards, can get a good one for 200-250 which will guarantee you at least 660ppd without bonuses or OCing. Good bang for the buck

That's why I said to get a 1900. Plus you can fold on it .

[frozndevl]

My suggestion was instead of the C2D. Granted, the C2D on a few of those WUs can get crazy ppd, in general the gpu will give you much better points. That's why instead of building a whole new box after christmas, I'm going to buy at least one 1900 or 1950 and fold on em.

[ustorfixx]

yeah if you have any x16 slots I would just go with a gpu folder, if its a single core processor in the box stop the cpu folding if its a dual core do one cpu folder and one gpu - two gpus stop both cpu but you need dual core to run dual gpu folders according to stanford.

I was under the impression that a GPU folder only needed like half a core per GPU? So like... 2 x GPU only needs one core to for it?

Well I am still in the dark ages AGP for me. I was going to hold off till income tax time and build a hole new rig for me and pass mine down the line. i might just spend my money on the kids for christmas and just wait till then.

[frozndevl]

I think the AGP x1900 and such cards do fold reasonably well. As for the requirements of the GPU, the way that it works with DX9, it is constantly polling the cpu so I believe it still needs 1 core per gpu for the most PPD.

That really makes me not interested in GPU folding anymore...

[frozndevl]

How come? Figure most you can get on an x2 core is something around 250-300 if you get the Bonus WUs. If you sacrifice that core for an x1950, you can get 660+ PPD. Nice bang for the buck

[DSwarP]

I guess it works if you already have the x1950... I don't know, seems wasteful to me.

[frozndevl]

How is it wasteful? can get a net of 300-500 more guaranteed ppd for a minimal investment, instead of having to spend 700 for a new rig

[DSwarP]

No no I just mean like... having a core.. not running FAH. The humanity!

[frozndevl]

Yeah, that does seem so very strange... but think of it like this...

1 cpu = 1F@H
1 cpu + 1cpu = 2F@H
1 cpu + 1gpu = 3F@H

So, dual core...

1 cpu + 1 cpu + 1gpu = 4F@H.

Net effect is positive (exactly ZERO real math behind that). Think of it as an ingredient for a super folder!! Much like memory.

Interesting math....

Because of the cpu polling issue with the gpu client, you need 1 core per gpu client. That give three configurations using a PD, C2D, or X2:
(in order of increasing ppd)
2 cpu clients
1 gpu client +1 cpu client
2 gpu clients

[frozndevl]

1 cpu + 1 cpu + 1 gpu + 1 gpu = 6F@H

Yeah, it is definitely interesting math.

[DSwarP]

Wait what? Didnt you just tell me you need cored dedicated to the GPU FAH? So CPU + GPU = 1 FAH?

If your system has 1 single core processor (ie P4, AXP), then you two options:
1) 1 cpu client
2) 1 gpu client.

If your system has 1 dual core processor (ie C2D, X2), then you have three options:
1) 2 cpu clients
2) 1 gpu client +1 cpu client
3) 2 gpu clients

There is an additional option for dual core processors, and while it does increase PPD, it increases the time for each WU to finish. Stanford wants WU's completed as fast as possible, since they are used to generate future WU's. It the same as the old HT argument of yesteryear.

4a) 2 gpu clients + 1 cpu client (max ppd, but increases time to complete individual wu's)
4b) 1 gpu clients + 2 cpu client (not as good as 4a, but max ppd for 1 gpu)
5) 2 gpu clients + 2 cpu clients (worst combo, don't use. will negate gpu folding gains)

Hopefully the polling issue is fixed someday, and there is no longer that bit of trade off on #4. Thats the only reason I don't give 4 as a config, though others may. 4b takes more of a hit on the gpu client than 4a does. Option 5 will effectively negate the performance benifit of the multi GPU client.

See fahinfo.org for some ppd info.

I'm also in the dark ages with a 9800pro, x800 and mx440, all on axp and s754's.

Hey guys I'm back to that orange color I like again... yay!
