Be sure to select the Quad core for both primary and secondary CPU's.

check this link before jumping on that 1430.

It's a great little server (more like a beefed up workstation to me). I totally forgot about F@H. I run it on the PS3 and will definitely have to run it on my rig

8 instances of F@H on one rig..oh that's just not fair.

 

[SandEagle]

any recommendations on which client I should install? the high performance beta (5.91)? 6.0 beta? or standard 5.03?

[Uppsala9496]

Go with the SMP client (5.91 beta).

I think since you have two processors you can run two instances (one for each quad core).
I'm not too sure on that though.

Remember: Team 198.

I fold with 1x A64 X2 4200+ (oc 2.64ghz) with a radeon x1950 pro 512mb. If i fold 24/7 with the SMP client i can generate upto 1000 points per day, which has me hanging around 30th in team production. Seems my pc generally isn't on all day I have trouble meeting deadlines and fold with my x1950pro thats good for ~550ppd. A little while ago I had a mates C2D 2.4ghz folding along with my 4200+ and was generating 2600-3000 ppd that moved me into 17th in team production

I fold 24/7 on my c2 quad Q6600 @3500 it generates 3500ppd or 2 WUs per day

found this in another thread. Not as crazy as the Dual core deal from Dell, but a pretty good deal in its own right. http://www.newegg.com/Product/...x?Item=N82E16883102034

After selecting 1.86 ghz quads for both, and 2 gig memory, and Linux SUSE, its $1347. I could build 2 Q6600's @ 3.4 ghz for that price, forget that box....

 

[xbassman]

Wow...I haven't checked in in a while.
I still find it amazing how much more PPD the SMP client gets.

I have 9 boxes:

C2D E4400@ 2.66 (I can probably get a higher clock since I just installed a video card)
Barton 2500+ @ 2.2
Barton M 2500+ @ 2.2
Barton 2500+ @ 1.8
Barton 2500+ @ 1.8
Tbred 1800+ @ 2.3
Tbred 1800+ @ 2.1
P4 2.5
P3 966

The Core2 box is getting about 1500 PPD with the SMP client and the other 8 are getting around 1200 PPD combined!

Damn thats your secret. I swear I will catch up to you sometime this year!

 

[Rhoxed]

All i have is a 3800+ x2 @ 2.7 24/7 (about 1,200 PPD)
XP 2500+ @ 2.1 24/7
and a Pentium M 1.6 24/7

That XPM 2500 should be able to run faster than 2.2GHz ,I had mine at 2.5GHz!

whoa! :shocked:

I suppose it might, but I think the ram will hold it back.
Heck it has been running @ 2.2 so long it probably thinks it is a 3200+.

Whenever I get a chance I will definitely see how high my E4400 will go though....

I really didn't spend any time at all overclocking it since I was using onboard graphics.
I just upped the FSB to 266 and left everything on auto. (Asus P5K-VM)
All the settings have changed quite a bit from the Athlon boards.

RAM isn't a problem with XPMs ,just raise the multiplier ........err that's assuming your mbrd has that ability.What RAM have you got?
Btw I had an unusually good XPM 2500 ,I actually tested it at 2.63GHz!:Q ,but it got rather warm at that speed & voltage!

It's on a Shuttle NF2 Ultra-400 board that is capable, ram is Corsair value ram (DDR400).

It also is in a bedroom, so it is setup more for quiet then speed. I don't think I am gonna get more speed without replacing the HS/fan.
The only real world difference it would make is about 20 PPD for folding@home and none for the are apps run on that box.

How many points does the XPM give atm?
What temp is the CPU at running F@H?

Barton XP's @ 2.2 are getting around 190 PPD atm (bonus wu's)
It runs avg 47C (software) it'll start EUEing F@H when it hits around 52C and needs the dust blown out.

The XP-M is definitely a better chip than the Barton XP I have running at the same speed, but the desktop processor has a Thermalright copper HS (800U) and the XP-M has a cheaper aluminum HS.

I appreciate your interest, but I don't think I am gonna spend any time or money with that PC.
That old thing has been around a while and almost nothing that would help speed it up more would migrate to a newer box.

 

[Assimilator1]

Fair enough ,that would be a rather modest gain (~10%),just for interests sake though ,you have a little headroom temps wise.

What's 'EUEing F@H' ?

 

[JeffCos]

Just hooked up my PS3 and downloaded the folding client. One question though, I don't actually have to leave the PS3 on for it to fold, do i? I set it to auto start after 10mins and then turned it off which is i guess considered standby. Will it still fold?

 

[xbassman]

What's 'EUEing F@H' ?

EUE = Early Unit End

It happens when F@H becomes unstable. (not always because of hardware)
My athlons start becoming unstable when software temp readings hit around 50C.
Never really enough to crash the computers, but if I see an EUE it is a reminder to blow the dust out.

If you mean you turned off the monitor/TV that the PS3 is hooked to then it will continue to fold. Although I would check stats to make sure, as there used to be a bug that stopped the folding if not connected to a certain type of TV until it started folding.

I didn't know there was standby on the PS3.
If you mean the new PS3 F@H screensaver then yes it will continue to crunch, in fact with the screensaver going you will get better PPD and use less power!!

In addition to xbassmans' explanation I will add:

EUE is what it is called in the log.

You can have a stable overclock for everything else but it might be too high for some F@H WUs. I don't know, maybe certain F@H WUs push some parts of the CPU harder than other programs that test stability?

And like xbassman said, some WUs normally EUE on their own. Usually you will get partial points for EUEs because they still give the scientists data.

I doubt those people who claim to have a stable overclock have done a 24hr Orthos/Prime 95 test.

Exactly ! My new Q6600 G0 is perfectly stable@3.6, until you run F@H, then you get EUE's. I had to go down to 3430 to be totally stable with no EUE's.

There are 3 states the PS3 can be in...OFF would be if you turn off the power switch in the back. Standby is when you turn the on off switch on the front of the machine either on or off to play a game or do whatever. A red light on the front of the machine signifies standby mode and a green light with a blue light signifies the machine is running. I was under the impression that folding ran in standby mode, but i was wrong. The PS3 has to be left powered on to fold. While i'm not too comfortable doing this, reading what Sony and Stanford say, it's ok. I guess that's why I paid $50 for the 1 year unconditional warranty. I'm sure it'll break on the 366th day. Man does this thing fold though, .1246sec/frame...yes, that's twelve HUNDRETHS of a second per frame!!!

I wasn't too comfortable either at first.

My has been on for about six months.

It starts making more noise from the fan turning faster when I need to blow out the dust. After blowing it out it is quieter, kind of a built in safe guard!
