Geforce GTS 250 (65nm)

Are you saying it is based on 65nm because of GPUz? I ask because GPUz doesn't detect 55nm correctly on the GTX 260s either. I'm pretty sure all GTS 250s are 55nm.

i have a gts 250 and it idles at 60, and gets to about 74 in game, im sure yours is 55nm cuz of the low idle temp, but it looks like mine is 65nm which sucks cuz i was hoping to oc it, but it could be the cooling cuz i set the fan speed from 35% to 85% and it only dropped 2C or 3C

yeah i have lots of cooling in my case 120mm front intake, 80mm side intake and 2 80mm exhausts plus the psu and vid card exhausts, i have noticed that my new corsair 650w psu is blowing out warmer air and raised the temp inside the case a lil, my old ultra x-finity 500w even before i upgraded form a 7600gs to the gts 250 blew out cool air. I think ill take it out and check if its a 65 or 55 but that's what i thought 1 connector = 55nm

btw: i have the XFX GS250XYDFC gts 250, and my mobo is ga-m57sli-s4

edit: Apparently this is a common issue with my motherboard, with the southbridge heatsink being directly under the vid card and them using super cheap compound. i ment to order a heatsink for it with my gts 250 but forgot untill just after i finalized my order so ill order the rest today and see if that fixes it, ill order the EnzoTech SLF-1, and since im paying shipping again i might as well get a mosfet heatsink and some thermaltake A2482 12mm 17dp 50cfm fans, they push less air but should be way quieter then my 33db 90cfm aerocool extreme turbine, and they are also thinner

i cant understand why everyone is having trouble with the gts 250 and overclocking. i have the EVGA 1gb gts 250 (standard) and have over clocked it quite a bit i think ( i dont know its my first good computer)

core clock - 756 to 829
shader clock - 1836 to 2032
memory clock - 1100 - 1322

ive had no problems with articling or anything, it is 100% stable. my fan speed is at 80% and it idles at 33C. after playing crysis maxed out on 1280x768 for a couple of hours it reaches 45C.

I got my info on the over clocking from
http://www.hardwarecanucks.com/for [...] ga-24.html

all these settings workied with standard edtion the same way they did witht the overclocked edition. whats the point of spending the extra $20 on the overclocked edtion if your just going to overclock it more than that anyways?

The reason why one card idles @ a lower temp is due to the fact that not everyone has the same ambient temps, none the less the same cases and cable management.... Back when I was using a BFG GTS 250 (1GB), my idle temps were 37c and load 50c MAX but my ambient temp has to be at 25c or lower to achieve those low temps.... If my ambient is @ 30c or higher my CPU and GPU temps reach 54c sometimes higher... So in all you can never compare your temp to someone else's since there are many factors to consider.....

I don't overclock the card that far,

Max OC for me on a GTS 250(1gb) is 805/1920/1211 if I tried anything higher I would get artifacts..... I am pleased with the performance of the 250, even though it is quite expensive compared to the 4850, I think it is worth every penny.....

65nm? its suppose to be 55nm. I hear some companies are rebranding 9800gtx as gts 250. I would call evga and confirm it with them if its 65 or 55nm. the 9800gtx doesnt draw much power they really only need 1 pcie but to be safe they add two.
Did you try using the latest gpu-z?

would a 550 watt powersupply be sufficent enough to run 2 gts250's a quad core 95 watt 1or 2 dvd players 4 sticks of ram ddr2, and 1 or 2 harddrives?

its a diablo tech ps here is the link- http://www.tigerdirect.com/applica [...] CatId=1079

so far it has very stable voltages only changing .01- volts and .02 at the most.

Its what i could afford at the time, but so far it seems like a good ps. I didn't really read into it too much when buying.
-oh and thanks for the help so far

With my Gigabyte GTS 250 Zalman Edition I get

GPU Clock: 900 MHz
Memory: 1270 MHz
Shader: 2000 MHz

as verified: http://www.techpowerup.com/gpuz/ahx3a/


Idle temp: 44 C @ 4% Fan speed
Load temp: 75 C @ 6% Fan speed when running GPU version of Folding@Home.
