... I'm not even sure this card will go into this machine. Does it have a slot that fits? Does the PSU have the capacity and connections? The card wants two 6-pin or 8-pin power leads.

Heck, I don't even think the CD drive works, but I have a few dead boxes sitting around so I can swap that out if I need to.


The 630 should not need any extra power at all, my GTX 660 only needed one 6-pin connector as did the GTX-650 Ti.

The instructions in the box say to use two 6-pin or 8-pin cables. Peculiarity of XFX?

[edit]P.S. Regarding my gripe about UPS, I forgot to mention it was shipped from the store here in town, to a UPS sort facility about ten miles away, then back to the local post office, which is less than two miles from the store. That took from Friday to Tuesday. I think I'll just go get it next time.

Looking at a picture of a XFX GT 630, there is no power connectors on it and it only requires 65 watts of power.

Possibly it might be general instructions for all of their cards.

With PCIe specifying up to 75w for a x16 slot. Cards requiring less than that really should not need a power connector.

That is true but keeping heat off the motherboard will help it last longer.

Hmm. Well, I guess I should take the thing out of the box and actually look at it. (What a novel concept...)

I will often use newegg to get a detailed look at a product before buying it. Even if I am not buying it from them. They generally have several highly detailed photos of products.
Such as the two versions of the XFX GT 630.

... now that I have it, I'm chicken to put it in! Maybe this weekend...

You're just scared of all the dust and fur balls you'll find inside.

been there done th.....

That's part of it. But also, the computer it's going in has another one sitting on top of it, and I'll probably have to shut that one down and disconnect it to get it out of the way. Then, the one it's going in runs my radioreference.com feed (which is why I want to take the load off its CPU) and I don't want to keep that down any longer than necessary. Plus, I'm not even sure this card will go into this machine. Does it have a slot that fits? Does the PSU have the capacity and connections? The card wants two 6-pin or 8-pin power leads.

Heck, I don't even think the CD drive works, but I have a few dead boxes sitting around so I can swap that out if I need to.

Well, I jumped in and did it last night. Forgot about the bad CD drive and had to shut down again to replace that; you can't just go to xfxforce.com and download the drivers without having the CD in the drive.

Also learned and implemented an important lesson: wrap electrical tape around unused power connectors or you might short them against the metal parts of the case and short out the PSU.

Anyway, it seems to be working. I set up new prefs for it to use the GPU only (the whole point of this exercise was to take load off the CPU), but I have it set to NNT for all projects until it finishes the CPU work it has on board.

When I checked on it a couple hours later, the exhaust air coming out seemed to smell of cooking capacitors. I hope this is just temporary new card smell and not the PSU baking itself.

And yes, the card does not even have external power connectors on it.

I just joined SETI and I am running a 6 year old Dell Intel Core 2 duo E4600 @2.40GHz 2.39 2.00 GB RAM. It has been good faultless rig for home work but I have been wanting to upgrade and now that I have joined SETI I am motivated to do so.

I am doing a WU in about 1 1/2 hours and about 5 hours on the large WU's I get. What does and I7 do something like that in. I would like to hear some opinions and completions times of i7’s on SETI WU's.

I am looking at an XPS 8500 i7 with a NVIDIA GT 640.

I'm working on a budget box similar to your old one. I wouldn't worry about the CPU, the GPUs can do much more work than the CPU. Put a nice GPU in an old Core 2 Duo and it will work fine. I was going to put something like a GT 640 in the new/old build but have decided to just use my old 8800 GT instead. The old 8800 is still pretty close in performance to the new GT 640 although it uses more power. The 9800 GTs are about the same as the 8800 GTs and can be had for cheap. Try to keep the platforms separate. I've given up on having an ATI & nVidia in the same machine, the SETI scheduler always runs one out of work and nothing I've done solves it.

Here's the best bang for the buck I see right now, GeForce 9800 GT HDMI 1GB 256-bit DDR3 PCI Express 2.0 x16 It does use an extra power cord though, and looks to be slightly slower than my 8800 GT. You can see an 8800 GT compared to an AMD 6850 here Multibeam Work Note the older 8800 takes around 4 minutes for a short task whereas the 6850 takes around 3 minutes. CPUs take much longer... The best prices I see, on the cheaper, newer cards are the GeForce GT 640 & Radeon HD 6670 both at $50.

I think I've finally solved the mystery of my Intel DP43TF board. I placed this board back in the box over 4 years ago after voiding the warranty and then having the same problems those other people had. It appears the be extremely picky over what RAM you install. It has to be Exactly what Intel calls for, nothing else will work correctly. I've finally got the correct RAM, and the board appears to be working perfectly. The $25 Dual Core Xeon I got from eBay is working fine as well. I'm looking for a cheap box to install it in now...

Well, I finally pulled the trigger. It appeared I would need at least a 650 to get much better SETI performance than my 5 year old 8800, and I didn't want to spend that much on my budget SETI box. I almost bought the 9800, but the next day it went from $29.99 to 49.99. Oh well. It had to be an nVidia as it's eventually going in the Linux machine. I ended up watching eBay for a few weeks and finally got a good deal on a souped up 8800. It must have come from NewEgg originally as it also came with the bundled COD4 DVD which was unopened. That would place it around 3 years old. It looks fine, and seems to be working well. I still don't have a case for the Ubuntu machine so I placed it in another machine for now. It is using the Lunatics x41g App at present and running around 85-90% GPU load. My 8800 uses the same App but runs right around 95% GPU load. The new addition is preforming slightly better than the 8800 at a lower load. So far, so good.

Hi Vito,

Here's what an i7@4.5GHz can do. Look at the tasks and their completion times.
http://setiathome.berkeley.edu/show_host_detail.php?hostid=5643864

It runs 6 CPU and 6 GPU tasks simultaneously.
The GPUs are a 560Ti and GTX660.

RAC is a bit low due to the outages (not getting enough work).
