Better yet: disable anything you don't need in the BIOS, so that Vista won't even ask for drivers

So, since I can pull 2200ish from a 3780 with 320 I can only wonder how much higher the PPD on an 4xxx using all 800 shaders might do. But then what will the alleged 2000 shaders do on the next gen ATI when the 40nu GPUs hit the first of next year
yep. In Vista, the GPU2 client doens't use much CPU resources. I have dual 8800GTS 640MB (G80) cards in an Asus P5N32-E SLI, and the CPU is a Celeron D 356 @ 3.33GHz. Each GPU2 client uses just about 33% of that CPU. Even with two folding away at ~4500ppd, the CPU still doesn't see any more than roughly a 70% load.

In Cog's case, for example, by switching to Vista she could add about 2000ppd for each rig that runs the GPU2 client (and nothing on the CPU, since in XP she needs the CPU power simply to run the GPU2 client). However, with Vista, it's easy to run an SMP client (even on a duallie) or two SMP clients (on a Quad) together with one or two GPU2 clients. Obviously, you'll need to juggle with priorities (the GPU2 clients need to have a high or very high priority, otherwise ppd tanks), and the SMP client(s) will take a hit, but a nice overclocked duallie still should bring in 2000ppd.

2 x GPU per PC is fine as long as you have dual core or quad.
GPU2 on xp for me only loads 1 core so there are 3 cores left to allocate another GPU2 and 2 x Vmware.
Well for you, you have unlimited XP... for those who have options... Vista at this point has the better support.... I wanted the max ability to F@H on CPU AND GPU at the same time

Yeah... If I get some extra cash and pay off my loan soon enough, I might have enough $$ to pick up a decent mobo, probably used/open box deal Ill need to wait for, then pick up a good card to put in, and be slamming my own sick lil farm

And while I am still a green fanboy by miles, ATI does need the support to utilize the hardware... then again that leads me to think "oh its the drivers again" lol

well on my separate install of Vista I had basically cut it down as far as possible - disabling just about everything that is not needed to turn the computer on... I had vista running on 600MB, superfetch and PF were disabled, and was running pretty nicely

This is the idea I am trying to put forth.. Instead of using so much CPU power in XP... get a copy of Vista and you can GPU and SMP fold for 2-4k point increase on the machine, depending on if you have a dual or quad...


I just did some more testing and it seems Vista32 is a lot faster to fold than Vista64 when the computer is in use.... When the computer is idle, they pull about the same (within 100 ppd) but I notice that if I start loading around the net, oepning stuff alot, Vista64 as it can utilize more power, also suppressed folding a lot harder, dropping my PPD on CPU from 3100 to 2900, sometimes even 2800..... However the GPU didn't slow down at all in either case

EDIT: I would still take Vista64 as 200-300 PPD is nothing when your entire rig pushes 13k PPD

yep.

The GPU2 rig is running Vista 64-bit, and I don't use that one for other than folding purposes. All three SMP rigs are running XP 32-bit. I still have an unused copy of Vista 32-bit and will use that for the next rig with GPUs (which will be the AMD rig).

I am using a P4 524 Single Core overclocked to 3.45GHz and it is letting my 8800GT put out 4898 PPD. It was putting out just over 5000 with my E2180 so the P4 does bottleneck it some, but not much.

I used the following links to get my stuff running. I wish I could write a step by step guide but I don't think I could write a coherent guide like some of the other members here. Nevertheless, hope this helps.

Some things to keep in mind:

This is the ATI faq that you can follow...it applies to nvidia cards as well.

What about multi-gpu support and the -gpu switch?

Running multiple GPU2 clients, one client each on multiple GPU cards, is supported through the -gpu x command line switch. The setup is similar to running multiple SysTray CPU clients.

Copy your Application DataFolding@home-gpu folder to a new folder Folding@home-gpu2 (AppDataRoamingFolding@home-gpu in Vista)
Create a new shortcut for the first client, and be sure to use the correct Target: and Start In: information. Note that one has to be very careful with shortcuts, and in particular, make sure that the "Start in:" field is set correctly. If you are having problems with automatic core upgrades, it is likely that your short cut is not set up correctly.
Edit the shortcut properties to add the -gpu 0 switch to the end of the Target: field.
Create a new shortcut for the second client, and be sure to use the correct Target: and Start In: information.
Edit the shortcut properties to add the -gpu 1 switch to the end of the Target: field.
Except for the different -gpu x switch, the Target: field in both shortcuts will point to the same FAH executable. The Start In: field for each client will point to the two different Apps DataFAH folders. The Target: and Start In: fields for a SysTray client are explained in more detail below.

The display must be active on the GPU card you plan to use, and –gpu 0 will select the first board, –gpu 1 will select the second board, -gpu 2 the third board, and so-on. You will need to disable crossfire for multiple boards to be detected. You will also need to use different Machine IDs for each client. Currently, only one client is supported on a 3850X2 or 3870X2.
edit: looks like the core gets downloaded automatically so you won't need to replace it.

I think I have it working but the ppd dropped once i opended vmware and smp as well.
I have gpu2 with a core each and vmware and smp sharing core 0 and core 1

post #78 of 165
It looks like they are running the same project at the same rate... double check the log files and check the ID's and maybe even check your gpu's temps to see if they are both working.

edit: its funny how i'm trying to do the same thing on vista right now. (just got upgraded from xp)

Im wondering if this 350w seasonic psu will be ok running the 2 x 8800GTs and the Q6600? seems ok so far.

Oh man that sounds kinda of bad... I thought you needed at least a 400w power supply for one card...for two cards you would really be pushing it no?

edit: was doing some math and correct me if I'm wrong but those cards pull 110w each right? Plus your q would pull another 100w...plus whatever else you have hooked up (hdd, fans, etc). That would be pretty much all your psu could handle.... I think

but if you like living on the edge, I guess you can keep it like that
