Post:
Should I buy an AMD Bulldozer or Intel Sandy Bridge for crunching BOINC? I've just read a review with benchmark results and the Bulldozers are very slow compared to the Sandy Bridge CPU's.

But the benchmarks never contain anything about performance in BOINC projects so I'm asking here what to do. My signature shows the projects I'm running, but I don't run Collatz anymore, because I only have run it on a GF-8600GT 256MB which couldn't run any of my other projects, but that card has been replaced by a GTX-550TI.

So what should I do? Any pro's or con's about the 2 architectures?

Can the ASRock 990FX Extreme4 board with it's UCC feature (Unlock CPU Core) unlock the cores of the AMD FX-4100 or FX-6100 CPU's?

Has anyone with such a board been able to unlock the cores. According to another website they seem to be locked differently than previous AMD processors.

I thought you said NO DISCUSSIONS about the subject?! IF you are now going to this could get real polarizing real quick!

Yeah, sorry about that. I forgot I mentioned I didn't want to discuss that.

I already picked a board. It's 1 of those 2 Gigabyte board I mentiond a few posts earlier. And what is that EVGA madness thing...I don't want to offer my computers and labtop before I die. And I don't have a testament. So I have to see how I'm gonna arrange that my family doesn't get anything.

I already have a case, it's about 10 years old but it came with 2 fan's and a fancontroller, and 3 temperature sensors. And I got a really good deal today due to a pricing error by the webshop I bought my HD 6950 at. After I placed my order, I browsed through the website and looked at the Nvidia cards they had (I wanted to buy the 2 Nvidia's at another webshop), but while I was browsing I saw a Gainward GeForce GTX 570 1280MB GDDR5 priced at €70.80 so I bought 2 of them. The order is accepted and the payment is done, so I'm hoping they don't find the error before sending the cards to me. If I'll get them, then I've saved about €400.

I used this PSU Calculator and the one at the Coolermaster website (the first one has more options). Hmmm, I know see that they have the same options, you just need to press the advance link (top right) on the Coolermaster website. It calculated for me a PSU of around a 1000 Watts, but looking at the Ampere's on the 12V rail I'm going to buy the Coolermaster Silent Pro Gold 1200W or the Silent Pro Hybrid 1300W with fan controller. I hope the 98A or 105A respectively on the 12V rail will be enough to power the stuff.

And I chose Coolermaster because I already have the Silent Pro Gold 700W (from an RMA) and a bunch of extra cables they had send afterwards because the 700W PSU didn't have cables with molex connectors on them and I needed those for my IDE HDD and DVD-RW.

Here in the US I can get an Asus mb, model M5A78l-m LX PLUS socket AM3+, with an AMD FX-6100, this is an x6 cpu, for about $150.00, the memory is an additional $100.00 for 16 gb of DDR3-1600. The store is MicroCenter and it is in their latest ad! Skip a quad core and go to a 6 core with NO hyper-threading gimmicks! It does ONLY have ONE pci-e x16 slot though! For another $150 bucks though you could get a nicer mb with 3 pci-e slots on it, an Asrock model 990FX Extreme4, or an Asus model M5A99X EVO. For an extra 50 bucks, $199.00 for just the cpu, you could get an AMD FX-8100 cpu which is a FULL 8 core cpu! Either of the two mb's above will work with either cpu, the memory also stays the same.

I took a part of your suggestion and whas thinking about AMD Zambezi FX 6100 CPU, which costs 145 Euro and 1 of these mainboards,
Gigabyte AM3+ GA-990FXA-UD3 at 127 Euro or Gigabyte AM3+ GA-990FXA-UD5 at 159 Euro.

I think I'm going to put 3 GPU cards on it, the 2 mentioned in the first post but 2 of those Nvidia's instead of 1.

Which board would you think I should take and what kind of PSU would I need for that?

That doesn't really answer on what board I should take. for CPU I want at least a quadcore perhaps a 2500k (or i3 if they are quadcore). that way I could buy a board with 3 PCI-express x16 slots with 8-8-4 lanes. And a third GPU-card.

I'm already crunchiing with anGTX-570 and a GTX-550TI, both factory OC-ed.

I can't wait that long because I will be committing suicide in a couple of weeks. I just wanna use the money I have left, about 1000-1200 euro's to do some extra crunchiing for science and to get some more credits, so I can maybe get for example SETI above 1M and maybe MilkyWay to, that why I want to buy 1 AMD card together with the Nvidia.

And please, no questions about why I wanna do what I said (in the first line).

The PCI3 extra lanes comes with the Ivy Bridge CPU. the 2600K is PCI-express 2.

Well I won't have long to live (I have a deatwish for about 15-17 years, and finally ordered some medication to commit a working suicide attempt, after 8 or 9 failed ones).

It has to be ATX size board, well below 200 euro's, and I was thinking about an i7 2600K because of it's HT and unlocked multiplier but it may as well be a cheaper CPU so that I would be able to buy a 3rd GPU card. The PCI-express lanes will have to be well divided like 8-8-4, instead of 16-4 like I have on my current ASUS P5K-E Wifi-App, which has a GTX-570 (16 lanes) and a GTX-550TI (4 lanes). If I would go for an i7 with IGP the board should have a HDMI connector so I can dedicate the GPU cards to crunching, like I do with my GTX-570 by disabling the output via Nvidia's control panel. If I would go for instance with another unlocked CPU, the board should have options to OC it.

Edit: I don't know if there are cheap 2011 boards and if the 38xx CPU is available yet, the 39xx ones are about 500 and 1000 euro's. The PCI-express 3 standard does have more lanes though but do I really need that for crunching.

For a crunching system I need a mainboard for 2 highend GPU's. The GPU's I want to put on/in it are EVGA GeForce GTX 560 Ti FTW and a Gigabyte GV-R695OC-1GD. I want to put a i7 2600K (as it has HT and is unlocked) on it (but not necessarely), because I still run some CPU projects (Cosmology and LHC). I probably need a new PSU too as I only have a Q-TEC 550W lying around. I also want to connect 1 or 2 OCZ Agility 3 SATA III 2.5" SSD 60GB to it. Memory will be at least 2x Crucial 2GB DDR3 PC3-12800 (1600 MHz). But I probably add 2x 4GB more to it.

For Dutch, Belgian and maybe German readers (those that can read Dutch) I might have another proposal, which you can read here on the SETI.nl forum. You might get those 2 mentioned GPU cards for free.

So suggestions are welcome.

I too have gotten work from MW and from SETI, but not from GPUGrid. Normally I have 2 WU's on my system (per GPU), but now I only have one crunching and it won't request a new one. I'm running BOINC 7.0.15. I'm running GPUGrid on 1 GPU.

I know this is the MW forum but maybe there's someone who could help. I also posted this on the GPUGrid forum, but I don't know how long it will take them to response, and this thread here is going like a train.

Just upgraded to BOINC 7.0.15 but it's not requesting any tasks, for any of my projects except SETI.

EDIT: I'm running dry on all projects.

I'm using Nvidia but CPU usage is still quite high.

Where do I put --gpu-wait-factor and --gpu-polling-mode, and how to lower CPU usage even more?

I found out where to put it, but what numbers should I use to lower CPU usage?

BTW upgrading to the 7 series of Boinc means you have a whole other set of problems with your cache levels! And NO you cannot downgrade without wiping out all your existing units

Can I upgrade to BOINC 7 without wiping out all of mine existing/cached/running WU's?

Post:
You could use the alpha version of BOINC 7.xx with the <exclude></exclude> parameter IIRC, or you could run a dual directory setup. This means setting up an extra directory for BOINC (e.g. BOINC2) and run the project you want to run on the Nvidia in 1 directory and the project you want to run on the AMD in the other directory. Just never attach 1 project to both cards if your going to run this way. It can or will give problems, at least on my setup, but I'm using 2 Nvidia cards so that might be the problem.

I can't tell you now how to setup a 2 client/directory setup, because it's 5:34 in the morning and I'm ready to go to bed, but maybe someone else might be able to help you with that.

I myself haven't installed BOINC 7.xx because it's still in alpha stage, but the <exclude></exclude> parameter is very handy to assign certain project to just one GPU. So if you're not scared to run the alpha version, you might give that a try, but it can still contain bugs as it is an alpha version.

Maybe someone else can tell you more about BOINC 7.xx.

I hope this helps to explain the possibilities you have and it's up to you which way you go with it.

Edit: Arkayn posted while I was typing but he came with a good, valid and easier solution.

For Nvidia it looks like running 2 WU's on the same GPU uses a lot of the CPU's resources, while running 1 WU (still with an app_info.xml) uses a lot less. But running without an app_info.xml uses even less CPU resources.

Edit: I'm using driver 290.53.
