Finally had time to finish my quad core (X3210) folding rig

post #1 of 21
Thread Starter 
I've had a pile of components sitting around for the last three weeks, and I finally had time to finish the build today. To give some indication about how long the build process stretched out, my first attempt at booting the system failed...due to never installing the RAM.

My plan with the system is to dual boot Win 2k Pro and some flavor of Linux. Windows will be for stability testing, temperature monitoring, etc., and Linux will be booted 99% of the time for folding.

The 2k installation was quick and easy. It's a barebones build, so there weren't even any driver issues to slow things up. CPU-Z correctly identified the CPU as a Kentsfield, but it only showed two cores available. Poking around in the other programs showed the same result. Perhaps it's a Win 2k limitation, but that seems a bit odd.

Based on Knitelife's research, I decided to go with SUSE 10.2 for Linux. I booted off a DVD, it loaded up to the installation screen, and then for some reason it stopped detecting the optical drive (or for some reason could no longer access the DVD). My guess is a driver issue, but with only one IDE channel on a P5B Deluxe, I don't have much in the way of options other than buying a SATA optical, which is not high on my expenditure list at the moment. I tried the Internet install option off a CD, but that had the same issue.

I had an Ubuntu DVD lying around, so I tried that as well. I use that on my two Conroes through VMWare, so I'm fairly familiar with the boot process. It started up just the same as it does on my other systems, but it freezes up on the second boot item. I even let it sit there for about an hour and a half in case it was a slow step, but nothing changed.

I have the system down now for the whole AS5 thermal cycle break in thing, but I'd like to get this system running ASAP. Any suggestions as to how to get beyond these Linux install issues would be greatly appreciated. If I can't get anything worked out by tomorrow, I'm going to try that minimum install Linux SMP iso just to get the system doing something productive.

I had the same problems with the P5B Deluxe installing suse. It does not recognize the jmicron driver correctly. I ended up booting from a DVD, and then using a external USB Hard Drive as the source for the data.

I found this post after the fact from Whoodie that talked specifically about it.

One thing I found out last night... if you are going to install SUSE as a dual boot with P965 board or any other board that uses the JMicron controller you will need to load the hardware module prior to installation. This can be done from the first screen of the install cd, where you actually select install. There is an option to load hardware module, select it, then select the JMicron PATA controller. Otherwise SUSE will not recognize your instalation CD.
Since I already had mine working, I have not tried it. I have notice that there are a bit different drivers in the SUSE vs openSUSE 10.2. Maybe the openSUSE install had the driver that Whoodie referrences, and just needs to be installed during the start of setup.

You could also possibly put the install files on the windows 2k partition and load NTFS drivers and use it. I imagine the guys in the Linux section of this forum could give you better advice though.

Being a total Linux idiot, it still took me a while to decipher this down to my level. If anyone is in the same boat as me (and from Google searches, this appears to be a common problem), the exact procedure is -

Boot off OpenSUSE CDs/DVD
Select Installation/Wait for drivers to load
Get notified CD can't be found
Go through manual install procedure, select language, etc.
From the next menu, select the Kernel Modules option
Pick the first option from the next menu (the IDE one)
Scroll through the long list of devices, selecting the Jmicron one (I've seen it suggested that the generic one should be selected as well).
Go back to the post-error menu and select install

That'll get you to the point where you can follow the sticky SUSE install guide in this forum.

Phew, a whole lot of work just to read a DVD. It would be nice if Asus had a Linux driver for the Jmicron controller on their site or if the all-generic-ide boot option actually worked from the main installation menu as is documented various places around the 'Net.

Anyway, hopefully I can get this beast folding today. Temps are definitely going to be a concern even with the decent WC system I have on the rig. Maybe I should buy some dryer vent duct to pipe some cooler air to the rad. My goal is 3.0 GHz on water, but we'll see how that goes. Hopefully the native Linux install with somewhat make up for the reduced clockspeed compared to my C2D rigs such that the quad will produce nearly twice as many points as one of those.

Fedora might be worth a shot looking at. Ive had problems install Ubuntu before, but never any problems with Fedora.

I had my E6420 OCed to 2.8ghz, tested Linux folding, it was slightly better than my Opteron (17min/percentage vs 22). I OCed more to 3.2 or 3.4 then tried Linux folding again and i started FAH then Firefox (restoring a session) and it froze. Its never froze on me before, it was weird. However, in Windows, its been perfectly stable for 2 hours in Orthos. So i dunno. Just thought i would add that. Other than that Fedora has been perfect.

I got SUSE to work doing the stuff I wrote above. There was a glitch with the network driver during installation. It couldn't get online to download updates, but Firefox and such works now that installation is complete.

Preliminary results -

E6600 @ 3.6 GHz does a SMP WU in right around 10 minutes/percent
X3210 @ 2.13 GHz (stock) does a SMP WU around 9 minutes/percent

With two SMP consoles -

Ones goes about 15 minutes/percent with the other about 23 minutes/percent, which equates to right on 9 minutes/percent with a single console in terms of point production.

Note that these numbers are based on less than 10% of each WU, but it's a good starting point for comparison. I also currently have my RAM at 1:1, so it's seriously underclocked. I'm hoping to have some time to get the OC cranked up tonight and see what this all looks like with the system flying along.

Thats good news to hear.

Now all we have to do is turn OCN around from our downstreak...

Great to see you got it going. Did you assign each console too its own two cores?

I launch one console with:
taskset -c 0,1 ./fah5 -local -forceasm

and then the other with:
taskset -c 2,3 ./fah5 -local -forceasm

You should get better results because of the way the L2 cache is set up.

We've had a bit of a turn around the last week or two. We're still off our near 1 million per week mark, but we're up nicely from a couple of weeks back. I would really like to see us break the 1 million mark for a week before the next round of price cuts, and then blow that mark away further down the road when everyone has quads.

My first go was just running the typical Linux command (that being the second half of the command above). That should spread out both consoles over all four cores. I'll give it a shot with the other command for comparison purposes. Once I let that go for a bit, I'm going to OC a bit. I really wish I could get Win2k to recognize all four cores so I could properly stress test the system and get good temp readings on each core.

I am very happy about this slow turn around. I wish it would just happen sooner.

I'm doing my best to pull my weight.

Top 10 producer, YAH!

A bit off topic, but I would expect it to be faster. My main folder (P4, a bit over 3GHz, 512MB RAM) runs at about 7 minutes/percent. Any idea why the P4 is faster?
