I was given a "PNY XR8 performance edition 9800GT Pci 2.0 video card" after doing a puter upgrade. Will it be any good for crunching? I Desire Peace and Justice, Jim Scott (Mod-Ret.) |

I was given a "PNY XR8 performance edition 9800GT Pci 2.0 video card" after doing a puter upgrade. Will it be any good for crunching? A 9800GT is certainly capable of crunching, but I wouldn't say it was 'good', currently. I bought mine in 2009, when they were pretty much on the sweet spot between price and performance. But five years later, I took them out again, and replaced them with GTX 750Ti cards - roughly twice the performance for half the power consumption, and much the same retail purchase price. |

It will work. The fact that you got it for free is the only reason to use it. Does it have 1 gig of ram? |

If Jim_S's video card is like this one Here, then it may have 1GB ram in it. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

If Jim_S's video card is like this one Here, then it may have 1GB ram in it. My 9800GTs had 512 MB, and that's plenty for a single SETI task. Superficially, having 1 GB RAM allows you to load two tasks at the same time - but memory isn't everything. The hardware to switch efficiently between loaded tasks didn't arrive until a year later, with the Fermi (GTx4xx) range: I doubt (YMMV) that this card will show much, if any, speedup if you set it to run two tasks at once. |

If Jim_S's video card is like this one Here, then it may have 1GB ram in it. You are right. 512 MB is plenty and back then 512 was pretty standard if I recall correctly. When I asked if it had 1 gig, I did not imply that it would need 1 gig. I simply was curious what it had. I knew that it would have more that 256 MB, but not how much more. |

Greetings All May I ask a question on this thread instead of creating a new thread as it is to do with the thread title. Has anyone used a ASUS ROG MARS GTX 760 x2 GPU on Seti, and if so did you encounter any problems. I have an opportunity to either get one, or would it be better to get A. NVIDIA 780ti GPU or B. 2 x single GTX 760 GPU's. Any input would be appreciated. Regards Tazzduke |

The GTX 760 has 6 Compute Units (SMMs in NVidia speak). The GTX 780Ti has 16. The GTX 760 has higher clock speeds, for the reference cards, however after market GTX 780Tis will often be clocked higher than the reference model was. GTX 760 base clock 980 MHz GTX 780Ti base clock 875 MHz The GTX 760 uses up to 150W The GTX 780Ti uses up to 250W With the present applications you would probably get more work from 2*GTX 760s than one GTX 780Ti, but you'd also be paying for the extra power consumption. While i'd expect them to produce more work, I'm not so sure the 2*GTX 760s would produce that much more work than the one GTX 780Ti. Tough call. Grant Darwin NT |

Now an even harder decision to make. Regards |

Why not compromise and get a gtx 750 ti good performance,low power usage and around £100 to buy new Life is what you make of it :-) When i'm good i'm very good , but when i'm bad i'm shi#eloads better ;-) In't I " buttercups " p.m.s.l at authoritie !!;-) |

I have two graphic boards, a Geforce GTX 750 OC on my Windows 10 PC and an AMD HD 7770 on the Linux host, which is a 2008 vintage SUN WS. They have comparable results on both Einstein and SETI GPU tasks, but the Windows 10 CPU is faster and has 4 cores while the SUN CPU has 2 cores, being an Opteron 1210. I have seen them listed as 1374 ops/s the nVidia and 1350 ops/s the AMD. But the nVidia has 4 Compute Units, while the AMD, at least in the stderr.txt of SETI@home tasks, is said to have 10 CUs, which is rather a contradiction. Tullio I am running one task at time on the Windows PC and two at the time on the SUN, where I wrote the app_config.xml file. I am a Windows novice and has yet to learn how to create a file on Windows. |

Greetings All Well that was short lived ended up getting a GTX 970 for the same price. |

Greetings All Not a hard choice that one. Reference cards- GTX 970 13 Compute Units GTX 760 6 GTX 780Ti 16 GTX 970 Base clock 1050MHz GTX 760 980 GTX 780Ti 875 GTX 970 up to 145W GTX 760 150W GTX 780Ti 250W Even with less compute units the higher clock speed should give close to the same output for much less power than the GTX 780Ti, and less than half the power of a couple of GTX 760s. A very good buy. Grant Darwin NT |

Greetings All . . May I ask how much? If that is not a rude question. I am interested in going that route myself. . |

Greetings Sure no probs, its a reference model, $300. Sourced it through the GUMTREE website. The card was only just a couple of suburbs away from where I lived so that helped as well. If I can find what I am after locally otherwise I go the EBAY route if its interstate. Regards |

Greetings . . Even second hand that is an attractive price, I'll have to check out gumtree. |

Greetings Yeah its tough though, sometimes you will find a bargain, but other times you won't. I remember getting a HD 7970 for 120 dollars, and boy that card really could crunch up a storm, but then I got the next power bill, and back onto gumtree it went, ended up getting a couple of GTX 660ti's and so one crunched and the other was a backup, but then the next power bill came through, it wasnt as bad as the previous one, so both GTX 660ti's crunched but not full time. I used to crunch with 6 GPU's, but now down to 2 really top GPU crunchers and I am happy with that. Cheaper power bills but still doing my bit for SETI. LOL Happy Hunting. |
