I want to say zombie67 has a 295, but I could be completely wrong about that. It was certainly a beast back in the day (it is a dual GPU card), but I'm not sure about now.
Yeah, I had one. But the power consumption is stupid high. And the performance was wildly inconsistent. May have been defective. In any case, the 580 is WAY stupid faster. Many times over. Skip the 4xx and go with a 5xx, IMO.Quote:

I don't look at crunching costs based on purchase cost. That is a drop in the bucket over 2-3 years. The real cost is power. At least for me and where I live. For my small farm, I spend over $1k/month in electricity just for the crunching. So a $500 card that is 3-5x faster, and uses the same power or less is a no brainer.Quote:

I think power is going to be your bigger issue. I forgot you got the 465 - I'd probably skip the 295 then... though it is a bit of a shame to pass up...Quote:

I thought the 460 cards were pretty sweet performance / watt? Maybe I'm remembering "wrong" from some reviews I read, but I seem to remember when that one came out, many were breathing a sigh of relief that not ALL NVIDIA cards were power hogs...I have no idea where it sits in points / day, though.
Update. Got the GTX 465 today and it is indeed the Black version. :D Got it crunching PG with a slight OC (ok, a 100MHz bump in the clock speed) for the first couple of days just to burn it in. Used MSI Afterburner to up the fan speed and it looks like there is MASSIVE room for OCing. I will now have to research how to flash the BIOS to a 470.
Yipeeeeee!!! <:-P <:-P <:-PQuote:

And to add injury to insult, my system with the 5830 and 5850 in it is going wacko as well. Keeps telling me about every 8-10 hours that the video drivers have "failed" and stops crunching. This may be the part where I fall on my sword.
D@mn, what a major PITA. Sorry to hear it.Quote:

Good luck.

Might want to check this new nVidia card. It is supposed to be in stores today at $149.
http://www.compusa.com/applications/...125&CatId=3669
Discounts already on the EVGA card or they have an oc'ed one for $159.
Interesting. I was running a GTX 580, until the fan died and was only gettting 100,000 a day. Must not of been running Prime Grid. When I get the RMA'd card back, I'll try it.Quote:

Ok, next question. I got the GTX 465 working perfectly (so far) on a different system. I got the black version and everything I read says that the BIOS can be flashed to a GTX 470 with no problem. The "bar" in MSI Afterburned starts at 607MHz and goes all the way up to 916MHz core freq. Tried running it up to 916MHz but when I did, the sensors told me it had actually down clocked to 403MHz and the PG WUs ran alot slower so I set it to 700MHz and it crunches units in 16 minutes. So this leads me to conclude that once I get the card BIOS flashed, I should be able to OC this thing to its full potential. Oh yeah, there was a question.....I have never flashed a BIOS on a video card before so I was wondering if anyone had some guidance for me?
@Dan - Nice work! I like that plan. How many machines are you running?
@Joker - I found this link that may help...
Actually, the reason the card clocked down when you tried to set it to max speed is because it crashed. It's part of their built in safety features. The reason it clocked down could be that at 916MHz, cooling wasn't adequate and after it reached 105C, which may have only taken a couple seconds, it immediately lowered the frequency to keep from frying itself. It could also be that the voltage didn't support the card running that fast and every computation it did errored out. Changing the BIOS may not solve this issue, as it normally happens for physical reasons instead of software.Quote:

Thx Max. That post is from 2007 so it is still applicable to modern cards?Quote:
@Joker - I found this link that may help...
+1 to what JPM said - just because the software lets you, doesn't mean you should overclock that high. For my 5970s, Afterburner lets me go up to 1000, but I've never gotten it stable above 850 (currently at 825). I would suggest starting from stock, then going up in small (~20MHz) increments, checking temps, WU errors, etc. along the way.
And I believe what the BIOS flash does is unlocks extra shaders/cores (I may be wrong - someone correct me if I am) on the card. The clock is a separate issue...
EDIT: I think it is, joker, but here is a better link, I think...
Good info JPM. I am more looking for the BIOS update to increase my stream processors. I have read that a flash (with this card) will increase/unlock them from 352 to 448. Dont know if this is true or not but I would like to find out. That would be a pretty good OC in and of itself and any MHz increase would be a bonus.
I think you are right Max as far as the BIOS flash.
I'm running two i7 boxes with Bonic running 24X7, except when I'm gaming.Quote:

huh....must be screwing up the data somehow. I NEVER have a screen saver - it takes some CPU power that could be going to my BOINC account! heh! ;) I always just go into the power settings and make it turn off the monitor after 5 min.
See if that works for you, maybe?
Life is not that easy for me right now. I used to have the monitor turn off but then one day, for some reason I have yet to figure out, me monitor would not turn off. That message that tells you that your monitor is working but is getting no signal would just stay on the screen. dont want that burning into the screen. Ok, I say FU, i'll just turn off the monitor! Power switch on the monitor went goofy after about the third time I turned it off and it took me 10 minutes of pounding on the key to finally get it to come back on so I dare not turn it off again. ~X( And on top of it, I decided to switch 5830 cards in the machine that is giving my trouble to see if that would fix it and now I cant get Crossfire or dummy plug to work. b-( Windows, MSI afterburner and GPU-Z all tell me that there are 2 cards but CCC just refuses to find the second card and so BOINC is only using one of them.
Sounds like you need a baby or two to punch, joker...
Try this:
1. Uninstall CCC and everything ATI-ish. Do not restart.
2. Driver Sweeper (use 2.9.0). Restart.
3. Control panel - Device manager - Display Adapters. Right click and uninstall. If it asks you if you want to delete driver software, say yes.
4. Restart.
5. It will detect the cards - let it, then restart when it prompts you.
6. Download CCC 10.10 (this one has always played nicely with me).
7. Install 10.10. Restart.
8. It should prompt you if you want to use Crossfire - leave that box checked.
9. BOINC should see two cards. Hopefully...
+1 You could have the screen go blank or have it go sleep.Quote:

Glad you got it working! They should be rocking pretty good for you... keep us posted on how it works!Quote:

Update: The GTX 465 in its first FULL day of running (about freaking time) at stock settings (ok with a 100MHz overclock) has produced just over 400K credits today. Not bad for $140. I wish they were still in stock so all of you could buy one.
Happy to have "most" of my video cards working. Just to throw it out there.....anyone got an extra AM2 motherboard with at at least one PCI-E Slot laying around? I still have a 5830 card sitting on my desk because one of my systems wont run high end cards and the rest of them are full. It would replace a 4870 so it would add an additional 100K+ to the team.
