My First Folding Rig (My First Rig Ever!!)

post #1 of 6
Thread Starter 
After folding on my laptop 24/7 for about two years I finally decided to build a dedicated rig. Because of financial constraints I am getting pre-owned and refurbished components only. Here's the build and costs:

1. MB: MSI K9A2 Platinum Edition
2. CPU: AMD Phenom X4 9950
3. RAM: OCZ Platinum 2x2GB PC2 8500
4. CPU Cooler: Xigmatek HDT X963F
----------------------------------------------...................$163
5. GPU: 2x PNY GTX 465 Refurbished.............$218 (Thanks OCN!)
6. PSU: Corsair TX750..........................................$ 50

The primary objective is to max out on GPU folding. I plan to use a total of 4 dual-slot GPUs on air. The MB is very friendly with that. The CPU is quite an old one but I eventually plan to upgrade to an AM3 6 core (still not sure about this) to do some SMP folding as well. I will upgrade the PSU sometime during the process.

As of now I got everything except the power supply. One of the GPUs is being RMA'd so I'm starting with the other one for now. When the PSU comes tomorrow I will start folding for Team OCN asap! I can take and post pics if you want

This will be a headless system. So please suggest what type of monitoring program I should use to monitor hardware from a laptop running Debian Linux.

Overall, comments/suggestions on the build (and possibly on cost efficiency) are welcome.

Btw my electric bill is included with my rent, so no worries with power consumption

Let me get 2 points clear:
1. Now, you're building a Phenom 1, DDR2 rig?
2. You plan on running 6 core Phenom 2 on AM2 socket?

I wouldn't do that, mate
Better off invest in a better AM3 mobo and cheap AM3 AthlonII, then upgrade to decent CPU.
At least IMO that would be better/faster/more futureproof.
That DDR2 will limit you massively

Yes, as the CPU & MB came with the same purchase.

That is something I plan to do in the next ~12 months. The MB has an AM2+ socket; I plan to use an AM3 CPU on it to use the extra cycles.

Please explain the reasoning behind it. Correct me if I'm wrong, but Thuban CPUs perform better atm than their next gen counterparts, don't they?

Also, I found it rather difficult to find a good AM3/AM3+ MB with 4 double spaced PCIe x8/x16 slots.

While its true that in general, DDR3 has higher bandwidth than DDR2, DDR2>DDR3 in the same freq because of increased latency in DDR3. Remember that it will be mainly a GPU folding machine. If memory serves right, Fermi GPUs require less memory and CPU bandwidth to fold than the ones preceding it. That should negate any shortcomings of my current build. Don't you think?

If you post your ideas in the Folding forum, I think you would be surprised the sort of rocking deals you'll get from others who fold for OCN.

Reasoning follows: AM2+ limits your upgrade paths, the single power phase of pre-AM3 causes stability and safety issues. The combined price of AM3 mobo + low end AM3 CPU would be about the same of what you're paying, but for far better future upgrade paths and better overall performance.

Thuban IS better at the moment. I didn't advise you to buy Bulldozer, upgrade from Athlon II to Phenom II x6 would make more sense than upgrade from Phenom to Phenom II x6, because will allow you AM3 mobo, which is compatible with all new, even AM3+ CPUs. So when decent bulldozer chips finally make it to the market, you'll have one more upgrade option, +overall more decent system.

That's not quite true. DDR3 running on low DDR2 frequencies can do the same latencies as DDR2. Also, it is proven that frequency has several times higher impact on performance than latency, that is why overclocking goes freq first, tighten latencies later.

DDR2 won't allow you to overclock that x6 the way it should be (the lack of split power phase also will hinder OCing). Also, DDR3 is waaay cheaper, easier to add-up, has fewer problems when running multiple sticks, due to less stress on the DIMM VRM, due to lower voltage, emmits less heat and even cheapest sticks overclock quite good, which is not the case with DDR2

At least those are my thoughts

To sum up- with AM3 build you save money from RAM, get higher performance from RAM and CPU, be it Athlon, and have better upgrade path. IMO
