GTS 450 based on GF116?? What?

post #1 of 5
Thread Starter 
Hi guys, I recently purchased a new GTS 450 to run in SLI with my old 450. After booting up and installing drivers, etc i noticed that GPU-Z said that my new GPU was a GF116, not the GF106 as one would expect.
SLI seems to be working fine, no problems whatsoever, but I was wondering why Nvidia used GF116 chips in a GTS450 card?
BTW, both my 450's are "identical" Palit GTS450 sonics.
Thanks, Warweo.

Yes, there are reports of 450's being based off GF116's to meet demand. They had to stop producing GF106's anyways. A card having the same cooling solution or brand will not mean it will not have the same chip.

Your best bet is to ask Palit if they have a sure way to identify them by model or something or to send you one with a GF106 model. If SLI is working fine however leave it like that. GF116's tend to consume less power and clock higher than GF106's, so it would be a win for you.

Thanks for the reply, kinda what I thought already, but it's nice to have somebody clear it all up for me! Would 1GHz be possible on the GF116 or would I have to have both the cards at the same clock speeds?
Thanks again.

If they are the same clock speed then the SLI will work. SLI already downclocks the faster card to match the slower one. tongue.gif

Wouldn't be impossible. Hell, one of my GF106-based GTS 450's can get to 960 MHz.

Too bad in SLI the lowest clocked card is the one that sets the rhythm for all. I'd try testing each card, with their own volts (different chips may need different volts to reach same speeds), stabilize the lowest clocked card, and try to see if the other one can run with the ery same speeds but different volts (those does not matter).
