I ordered 2 750's, Question, will my downloaded tasks for AMD run on the 750? Or should I run them out first?

I don't think they will, I'd run them out on the old cards if I were you.

As an aside, I have a couple of 750Ti running great guns and to be honest, my research threw up that not only was the number crunching ability of the 750Ti pretty damned good, the power requirements are virtually nothing compared to some other cards.

They're PCIe bus powered, that could well be a biggie for people with smaller PSUs

I disabled my GPU downloads a day ago, but I'm sure I will be finger tapping waiting for GPU to finish so I can put new one in.

I can endorse the 750ti 's I have 3 of them running. Two in one machine, and one in another. They turn out very few invalids. And a boatload of work. Can't say anything bad about them

Brent,

Did you ever try that calculator that I posted?

Roughly, with not too many bells and whistles, it say that 350 may be enough to support those 2 750s.

What I could do is put them in and see if the computer starts up. If it does, then do a clean install of the drivers.

If that goes ok, then run BOINC and then Seti.

Once they are under stress and if the system doesn't fail, then you are golden.

The R9 280X I have, I just started running 2 WU's at a time with it. And it handles them with ease. MB's are being knocked off in about 7 mins each, 2 at a time. I am going to give it a few days and then up it to 3 at a time to see if the efficiency improves with it. It is not a titanX by any means but I still think it is the best 3 gig card for the price. Like I mentioned it was a tad over $200. I don't know what driver I am using, AMD prompts me to update when a new one is available. Right now it looks as all the calculations are running as opencl_ati5_nocal.

Again not a techie, it runs pretty darn quick from what I can tell. I shut this rig off when I go to bed so it only runs 18 hours a day give or take. I have never been an AMD fan with CPUs but I think GPU's work.

I can second this. The 7950HD I have completes work really fast.

Thanks for all the Info. I purchased a overclocked 960.

Not only there; I was given a [(hp)] "Enterprise" PC at work. It's proprietary-everything, including the power supply, so no extra PCIe power connectors. I had to wait until the 750Ti came out to replace the standard (IIRC) 440. :-(

---

Thanks for the calculator Zal, yea I think I should be ok. They are going in 2 separate computers, only 1 PCI slot in each one.

Recommendation for a app_config for 750ti?

should I install Luanatics for a 750?

---

You can use the Lunatics but the current stock Seti apps are basically the same now.

One of the nice things about Lunatics is you can specify that you only want the cuda 50 as opposed to cuda 42 so for that I would go ahead and do the lunatics

In theory you can do 3 MBs per card with the 750 Ti. I have mine at only 2 MB/GPU. or 2 AP/GPU.

You will need a commandline for the 750Ti for the APs. Here's the link to the discussion on 750s

http://setiathome.berkeley.edu/forum_thread.php?id=75919&postid=1588675

-use_sleep -unroll 16 -oclfft_plan 256 16 256 -ffa_block 16384 -ffa_block_fetch 8192 -tune 1 64 4 1 -tune 2 64 4 1 -hp

I pulled this from that thread. I haven't looked at my 750Ti machine in so long I have forgotten exactly what everything is set at. Looks like I'll be revisiting it this week. Thanks, lol....

It's been running without problems for so long that I tend to forget about it.

For the MB it will have to be a modified mbcuda.cg

http://setiathome.berkeley.edu/forum_thread.php?id=76993&postid=1657884

there is debate on this but at the least you should change priority to high or above normal

<app_config>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.5</cpu_usage>
</gpu_versions>
</app>

<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.5</cpu_usage>
</gpu_versions>
</app>
</app_config>

if you have Intel chip you can change the CPU value down to 0.04 I believe. I tend to use higher just as a buffer and because I find AMD needs at least 0.2 CPU but can go up to 0.4 on certain types of work units.

I assume you know how to make a app_config.xml?

If not then here is a link on that as well

Man, I'm getting lazy, cutting and pasting, lol

Good luck and let us know if you need assistance at any point.

Thanks for the info Zal, much appreciated.

Yea a know how to edit the config files, but it has been a challenge since no one seems to run R7 240s, so I'm winging it alone.

Trying to run my GPU tacks out for cuda tasks on new card. Thinking I have 2 or 3 days to go.

Should have the cards tomorrow, can put one in my slow computer (no gpu now) shut down a CPU for power, it should be fine.

Then once I get these tasks run off I can install in my main computer.

Hi Mark,

Got a couple of 970's and 1 x 980 here..
No complaints about any of em for crunching, saving up for another 980:-)

They are a tad pricey:-/

Cheers,

Cliff,
Been there, Done that, Still no damm T shirt!

*Grumbles* Where are my 750's? It's been 8 days and still nothing :(

Are they flying in 8 year old kids from China to build them? LOL

And the debate in my mind continues, How many ATI tasks do I want to have on hand before I switch to cuda? Ohh yea, throw in the issue of maintenance in the middle of it ... geesh.

*Still Grumbling*

---

You sure they didn't send them via the Giant Pink Snail?? They send a tracking number?

And the debate in my mind continues, How many ATI tasks do I want to have on hand before I switch to cuda? Ohh yea, throw in the issue of maintenance in the middle of it ... geesh.

You don't want to have any on hand. The ATi/AMD workunits are assigned to that application and that application will only work on that resource. I'd run down your cache first before switching over. Otherwise any workunits assigned to the ATi will not get processed and will expire if you switch before running down your cache.

yea, I know they are not compatible, that's why I'm debating how many to take before changing (i'm trying to keep them low as I can to when I think the new cards will arrive), and the inability to download during/after maintenance.

Right now it's ... the soonest I will see the cards is just when Maintenance starts, so 1.5 days "should" hold me over until maintenance is done and I might have new cards then.

Cheers,

My shopping list for video cards is 9 cards long,, at least, that's if I don't go beyond 4 PCs to 5 PCs.. Oh yes I have plans..

Now if one were to go to $250, then the choice is easier, the Asus Strix GTX960 on Amazon goes from $179.99 to 234.03 at the moment. Good luck.

I'm very confused with all this. Can someone shed some light for me. I was looking at the list of Top GPU models. The GTX 770 is at the top of the list. Why isn't the GTX 970 ranked higher? What determines the list? I'm running two computers, 1 has GTX 470s in SLI and 2 has GTX 650 ti. I have not changed any of the settings in the software, should I?

I'm very confused with all this... I was looking at the list of Top GPU models.

In short - don't look at that list

You should probably just turn off CPU computing and only use the GPUs. Furthermore if you are interested in SETI crunching you might just consider dumping the two 470s on ebay and buying some Maxwell card(s) from Nvidia (GTX 750, 750TI, 960, 970). They are way more effective and will pay for themselves in reduced electricity bill in a year or so.

Well shittly winks.

Put my first 750ti in my XP box and BOINC says "no usable GPU detected" :(
driver off disk was v340.52, but if it didn't like that wouldn't it just run errors?? http://setiathome.berkeley.edu/show_host_detail.php?hostid=7446133

I installed the latest and greatest BOINC version ... no change.

Any Ideas?

Also, and this really surprised me .... I use VNC to monitor/control my XP box, CPU usage (for VNC server) went from a few percent to a 42-50% after putting in the 750 ... WOW, and same screen res as before 1024x768 I find that really really strange!
