Best AMD proc for crunching

I recently upgraded my years old Linux box from an AMD X2 4100 with 2 GB of DDR ram to a AMD AMD FX 4100 quad core with 8 GB of DDR3. My statistics have improved greatly!

What I am trying to find out is if this is a good CPU to hand on to or if there is another AMD CPU that would be better.

I am using a AM3+ motherboard so I can use pretty much all of the new AMD CPU's.

What I don't understand about Boinc is how it really works on the inside. My system doesn't seem to use very much RAM to get the work done. I can toss another 8 GB of ram in this system for about $50 but I don't just want to throw away money and not get a benefit.

Thanks for any information fellow Boinc'ers.

Re: Best AMD proc for crunching

Hi utp216. I for one am very curious as to how your new Bulldozer processor is performing for crunching. Might you be willing to copy and paste part of your Results status/Return time page into a message so we could see the kind of run times and points you are getting?

Bulldozer is such a new design that most software isn't optimized for it, and I think it's unclear how well it will perform in many contexts (including crunching on different sciences).

If you only have 1 stick of ram it would be best to stick another 8 in the machine, but if you have 2 sticks of 4 each, then Boinc is just fine. If you can get a 6 core cpu it would be better, but by how much is debatable. Yes you WILL crunch more units with it, you can do 6 at a time, but the cost to do those extra 2 units may not be worth it. You will be spending x amount of money to do only 2 more units unless you can get faster cpu and a bigger L2 cache too. Boinc likes an L2 cache of at least as big as the unit is so it can load the whole unit into memory and not have to swap parts in and out as it needs tthem. Celeron and Duron based machines do not do as well as non Celeron or Duron machines for this reason. One thing to consider is to spend your money instead on a good gpu, ie video card, as they can crunch units MUCH faster than any cpu can. WCG does NOT currently support gpu crunching though, so if you only crunch for WCG then you can hold off on that. BOTH AMD and Nvidia make good gaming level gpu's that are suitable for crunching but there is ALOT to learn before buying your first one!!

Re: Best AMD proc for crunching

I am running 2 X 4GB sticks of Corsair RAM in this box.

I didn't know the core of my CPU was called Bulldozer. NICE!

@kateiacy I will get the data you were speaking about and post. The machine is finally put away and doing what it was intended for. While I was building I had it hooked to keyboard/mouse/display to make sure everything worked. It's finally headless in the basement of my house. I'm letting it run for a good 24 hours then I'll post some statistics.

Thanks guys!

BTW, kateiacy how did you get the cool signature with your statistics?

Hello utp216,
Look at "I made a new forum signature." in the Chat Room forum. Just post on that thread to get your signature.

Re: Best AMD proc for crunching

8 gigs of Corsair RAM is fine. However for 50 bucks more to double the amount of RAM (provided the model of RAM is compatible with the Motherboard in the configuration which I take is dual channel?) may be good unless you just need that money for something else. Also are you going to be using the same speed of RAM or are going to upgrade it? Sometimes what is more important is the model of RAM and it's speed rather then how much of it there is. But Corsair does make good gaming ram so odds are you don't see that much used of it being used due to how good the RAM is at doing it's job.


My ram is triple channel. Six slots but I have 3 sticks of 2 gig Kingston Hyperx Ram in it currently. Can ramp up to 24 gigs. May do that in two years if I can get a good price on the 6 sticks of 4 gig RAM that can be used in the motherboard.

For a computer being heavily used for other things besides crunching, getting an additional 8 GB can be an advantage. For a headless computer sitting in the basement only crunching-away on work-units (and dust-bunnies), it's doubtful any extra memory would have any positive effect on a quad-core computer as long as computer is already running in dual-channel mode. (Amd doesn't use triple-channel-mode).

Re: Best AMD proc for crunching

Yeah...avoid the ram upgrade until you actually have a need for it. Right now, most of the WCG projects are well under what you have in that system as is. However, you would probably see a bigger speed boost by going to solid state hard drives if you haven't already. Being a dedicated cruncher, you could probably get by with one of the cheaper smaller ones. Depending on the projects (CEP2 for example) you may find it to be the single best upgrade over all.

Re: Best AMD proc for crunching

I am planning on another 8GB in a few weeks when I have the extra scratch. This box also is my VMware host and from time to time I am running VM's actively. I only run them when I have to to conserve on CPU resource.

It is also serving all my files for the rest of the machines in the house.

I can't wait to see what this rig can do. It wasn't that much to put together and so far it has been worth it!
