Hi, Blurf,

I travel regularly throughout upstate NY, and would be more than happy to help you out if I can, Also, I'm interested in the 460... let me know.


Thx I PM'ed you

Card is working nicely but this continuing Nvidia driver issue is unnerving.

The screen will flash and then say the driver has reset itself. Happened with the 460 and others I've talked to say they get it too

I used to get that, but only very, very occasionally.
Since getting my GTX 750Tis, and running with 335.23 drivers I haven't had it occur (that I'm aware of).


Some of the causes are related to hardware, others drivers, others a combination of both- and not necessarily video. I think some people have had issues with their wireless network card drivers causing excessive DPC delays, resulting in video timeouts.
Try downgrading to the 335.23 drivers.

If that doesn't help, then DPC Latency checker (doesn't require installation, just download & run) will show if there are excessive delays, or an excessive number of delays. If there are, then it's a major PITA of disabling, then re-enabling hardware, to see what's causing them, then trying different drivers once you find the problem hardware.


Another option is to edit the registry & increase the timeout period before the driver restarts.

KeyPath : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers
KeyValue : TdrDelay
ValueType : REG_DWORD
ValueData : Number of seconds to delay. 2 seconds is the default value.

Try setting it to 3 or 4 seconds & see if that stops the problem, without causing any other issues.


Another option is to disable it
KeyPath : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers
KeyValue : TdrLevel
ValueType : REG_DWORD
ValueData : TdrLevelOff (0) - Detection disabled

The problem with this is that if the driver does actually hang, you have to re-boot the system to recover- like WinXp, 98 etc.

I don't like doing registry work but I'll keep it in mind-thx Grant.

I think about replacing the G210 in my desktop. The computer is rather old and did run a lot and I have the feeling that it may die soon, so I don't wanna spend a lot of money.
I found a GT630 for under €50, the Kepler one with 384 cuda cores and a TDP of 25 watts and I think about buying this card. You guys think that would be a nice replacement for my G210? And would it work well with my CPU (E5300)? Could I crunch on both cores plus GPU or would I need one core to feed the card?

PS: Here's a link to the card:

All most anything would be a step up from the GT210.
If your power supply could handle it (400W or so) a GTX 650, or a GTX 550Ti Boost would be good options at the right price.
But certainly the 384 core GT630 would be a big improvement (the other lesser models wouldn't be that much of an improvement for the price IMHO).

As for freeing up cores, that's generally only necessary for doing AP crunching, or if running multiple video cards and MB only crunching.

I don't wanna get a card that uses more power because I'm not sure if the power supply could handle it. The 630 would for sure be a improvement, my G210 has 16 cuda cores IIRC , LOL.
The only thing that makes me a bit unsure about this GT630 is the fanless design.

I attached a fan to my fanless GT 8500. The fanless design they implemented could not really handle running SETI@home 24/7. I just use some small 60mm fan I had lying around and connected it to run at 5v, instead of 12. So it just pushed the heat away from the heatsink.

A GTX 750 Ti has 640 CUDA cores and has the same minimum power supply requirement as the GeForce 210, which is 300 Watts. A GeForce 210 is listed at 44 GFLOPS, the GT 630 is listed at 310 GFLOPS, and the GTX 750 Ti is listed at 1389 GFLOPS. Of course the GTX 750 Ti costs more and uses up two slots

Oh, you are running one of these high end-cards with 16 cuda cores also? I wonder if it is as blazing fast as my G210 ;-)
Anyway, TDP is lower on GT 630 (25 watts vs. 45 for 8500 GT), so maybe it could run without fan also. Not sure though.

Damn, did you have to write this?? ;-) That's really tempting. I guess I have to rethink this all again.

The things to consider with the GTX 750 are 1) is there room in your case for it. Some computer case have height requirements so make sure you don't need a low profile graphic card. 2)Most of the GTX 750 occupy 2 slots so make sure you have the room (nothing like trying to put it in the case and see there is not room on the motherboard) 3)Make sure that it doesn't require a 6 pin connector. Most of the GTX 750 and 750 Ti don't require it but 1 or 2 of the higher end ones like those with the ACX fans do require an additional connection. I have both kinds, half don't have a 6 pin and the others do, so make sure of this last one. I was going to mention them as well (the GTX 750s) but didn't want to open the flood gates, lol.

The other aspect of power to consider is that the TDP of a G210 is ~30.5 watts, the GT 630 ~25 watts, and the GTX 750 Ti ~60 watts. Any of the 3 of course will operate from a 300 watt ATX PSU which delivers sufficient clean 12V power, but actual PSU capability decreases somewhat with age.

However, if a 750 Ti were unstable on the existing PSU that would probably be a good indication the PSU is getting close to the end of its useful life anyhow. IOW, although it was supporting G210 crunching it might not have done so for many more months...

I am considering some upgrades to my setup, mainly adding two graphics cards. I currently have a GTX 780, so I will be adding another for SLI (it's a gaming rig). Which leaves me with a 3rd slot that I can fill, but not in SLI (motherboard doesn't support 3 way SLI, already regretting my choice).

The motherboard manual says that it has 3 x PCIe 3.0 x16 slots (support x16, x8/x8, x8/x4/x4 modes). Nvidia cards requires x8/x8 to work in SLI, does that mean if I add a 3rd one (not in SLI), it will affect the 2 in SLI? if so, then I will be limited to 2 780's.

If I am wrong, which card would you recommend as a 3rd one? It will be used for crunching only. Power is not an issue, I've got a 1275W PSU. Cooling might be an issue and price, since it is only for crunching.

In both cases, should I consider any other bottlenecks? i.e. CPU (it has a i7 4770K)?

Ladies and Gentlemen, please say hello to my new card:








I got it yesterday for a little bit more then 100 Euros. After I installed it the screen stayed black and the computer made strange noises. I had to update the BIOS and the chipset drivers to get it to work but now everything is fine. I crunched a few WUs yesterday which took around 100 minutes on my old card, those were done in 12 minutes. Then I changed the count value to 0.5 and it took the card 14 minutes to crunch 2 WUs.

You guys think that running 2 tasks on the GPU is best? Or shall I try to run 3? Also I wonder if Cuda50 is best for this card? I saw a user with a 750Ti this morning which had a higher flop count on Cuda41 then on Cuda50.




PS: Thx again to everybody who helped me to choose my new card!
