Actually, it isn't all that loud, but then again I'm in a machine shop and there is a fair amount of background noise going on. All the fans except one are 120mm or larger, so that does cut down on the noise.
And all that hot air is going right into my face. Seriously, there is an exaust fan on the side door pointed right at my face. The A/C here isn't all that great, so I'm sweating for the science!!!

Of course since then I've replace the cooling on the bottom card, so it does look just a little different.
However it has locked up twice since then, and the board reset the overclocking settings to default. :bang head
Oh well, could be worse. So, this weekend, I'm going to leave it completely un-overclocked. Just to make sure it is stable. Then I'll start cranking the cards back up and checking the temps. I'm serously thinking of leaving the board as it is, un-overclocked. I've only got 1 SMP client running on it, and I could only get it up to just under 3.0Ghz when just 2 SMP and 2 GPU.
I'm down about 1K PPD as a result, but I was loosing more than that when it would shut down at night (actually lock up and idle) or worse, over the weekend.
So, after this glitch, things should be doing well.
My roomie is playing Spore, so her machine isn't kicking out much, but all told, I *should* be kicking out close to 40K ppd total. My ppd stats only show about 28K ppd, so look for a jump this next week.

Good lookin' stuff there torin! :beer:
Glad you got it worked out. :)
I've been meaning to update this for a while, and since Harlam was nice enough to point out that I was passing up on a 10% PPD increase, I figured now was the time.
I decided to drop the SMP client on this machine. (I've got 4 SMP clients running on my home machines.) So it was averaging about 20200 PPD with sometimes hitting about 20400 PPD. I also figure I'm doing a little better on the cooling with the CPU not working as hard. However, the other person who has a cubicle in my chunk of office space asked the maintance guy if he could help cool this area down more (Our AC comes from unit that has a sensor in the next room over, so when we are comfortable, they are ice cold.) He put a fan in the duct, so it is a little cooler in here now, but I've still got quite a bit of warmth on me.
Since I've installed the 1.13 cores though, my PPD seem to be about 22200-22400 PPD.
I really should take newer pictures of what I've got in the case now.
But overall, I'm really pleased with how it is working out, even if I am dealing with being perpetually warm and contributing to a slight decrease in time to the heat death of the universe.... ;) :beer:

ooo can't wait to get home and update my cores!

Just FYI, I had to drop my overclocks somewhat due to extra heat and needing better stability.
However, I'm still at 21700-21900 PPD. :santa:
Edit: Oh, and I forgot to mention it earlier, but for some reason my SMP client was down to about 600 PPD when I decided to drop it. Don't know why it kept going down. It was lower that it should have been with only 2 GPU2 clients running, which is not happening on my VM machines, so I'm still kind of confused about it.

I think you can do it on the board I have, but not in this case. It only has 7 slots out the back.
Benching station it should be possible....
Should be able to get about 40K PPD out of it with the new drivers.
Cooling is going to be tough though....

Your probably going to have to water cool 4 GX2s with the heat and cramped space. If 4 cores makes that much heat, I bet another 4 would add some more, lol.

just leave the side off, or water cool. but if it was just a folding machine, water cooling would be wayy too much $$. the blocks for GX2s are like 200 bucks lol.

Nope, 4 video cards. Each one running a copy of the GPU2 client.

Yep, that is the way my other two systems are set up.
My media server only has 1 PCIE slot, so I've got 1 GPU2 and 2 SMP clients on it. My main computer has 2 PCIE slots, so I've got 2 GPU2 and 2 SMP clients on it. It is my work computer that seems to be having a problem running both clients.

The one that runs two SMP and two GPU clients is that an eight core computer?

Yea I'm not going to do it because idk if I fufill the requirments for the GPU besides I'm not in it for the points. I monitor them on my account, but I'm not in it for them. Torin3 did you check to see if the reasons why the GPU won't work on your work cpmputer is because it doesn't fufill the requirments?

Nope, they are both single quad core CPU computers. I run the SMP clients on them in Ubuntu inside of VMWare Server. The free version of VMWare only sees 2 cores of the CPU. So I have two Virtual Machines running, each seeing 2 different cores on the 4 core CPU. SMP only needs 2 cores to work I just have to adjust the affinty on the processes so that there is one core free to handle the GPU2 client. (usually setting it to use cores 0\1\2, with 3 for the GPU2)

GPU2 needs an 8x00 series or newer card from Nvidia, or a 3xxx series or newer card from ATI. The client is dead simple to set up, but you should probably use a quad core if you are going to do both SMP and GPU2.
I think the reason the SMP (not GPU) is having a problem on my work rig has to do with the way the motherboard handles communications between the clients and the data. With 2 cards running GPU2, I had a signifigant drop in production with the SMP client. This didn't happen on my home machines. Adding 2 more cards, slowed it down even further. I was also have a few other problem with it and general stability of the motherboard, so I decided to not run the SMP on it.
I'm still running a total of 4 SMP linux clients, so I'm doing a variety of work for Stanford.

Try to oc your work machine. As for me ok I'll try to install the GPU. SMP is what I run now and my CPU is a quad. so yea.

It doesn't overclock very well at all

Tried installing the gpu but didn't have the cuba file it wanted so I got rid off it. What cooling system do you use? (fan, water or LN)
I don't remember the exact change-over point on the drivers, but I know 177.35 and above will work for the Nvidia cards.
Also, it is strictly air cooled. Fans on the cards, fans on the CPU and fans on the RAM and fans in the case.
I water cool at home.

science, just to get something straight, noone uses LN/2 for 24/7 cooling, it's expensive, and is only used for short benchmarking runs.

Ok so did you try uping the rpming of the fans for an oc?

The fans are all on maximum settings.
When I was overclocking it the temps were fine. It is a different problem.

I thought the problem was that your cpu can't power through that many clients. Maybe you should switch it to being water cooled.

I don't think it is a CPU problem, I think it is a motherboard problem. The motherboard doesn't have a lot of overclocking options and even when it was running only SMP clients, it didn't overclock well, and the temps on the CPU weren't that warm in the first place.
Water cooling can keep the CPU colder, but if the problems aren't related to heat, cooling it down further won't help.
The previous motherboard I used with this CPU overclocked well, and I was able to get a much higher overclock (and a warmer CPU in the process) that was very stable. So I know the CPU is capible of a good overclock, and it is this motherboard that can't handle it. And it isn't a heat issue for the CPU.
However the previous motherboard only had 1 PCIE slot on it, and I wanted to try multiple GPU clients. So I got a board that had 4 PCIE slots. However on this motherboard it is impractical to try and run SMP with 4 GPU2 clients, so I dropped the SMP in favor of using this board to its best advantage.
Added to this, while I paid for all the parts in this machine out of my pocket (including the OS), this is the computer I use at work. My boss has been very clear that he doesn't want any computers here watercooled. I admit that this disappoints me, but I like the job and plan on keeping it, so I do what he says.
If he'd let me, I'd have all the dual and quad cored machines at my work running SMP, but it takes up too much of our limited bandwidth, so my boss pulled the plug on it for all of the machines except mine.
I'm happy that I'm able to use it for folding and have my work pay for the electricity (It uses almost 700W when you add in the monitor).

Wait if GPUing is the issue why is it the motherboard's fault? Doesn't GPUing stress the video card/cards in the monitor itself? As far as the motherboard oc issue go to a great tech store (for me that's Fry's) and ask them what type of motherboard they use for extereme chips cause those chips enable ocing. :) (it says on the intel site)
