    Nvidia GTX 970, Standard or OC version?

    Ed2149

      Following some fantastic advise I have had from the forum regarding the configuration of some workstations I am about to buy I am looking at completing the systems with a GTX 970.

       

      Having had a look around the big distinction between the multiple branded versions on offer is the clock speed. As gaming cards there are many over-clocked versions for enhanced performance, but I was under the impression from speaking to a PC builder specialising in editing systems that it was preferable to sick to cards with their original clock speed to keep heat build up to a minimum - this may not be true now with maxwell architecture.

       

      Having looked at the options for the standard clocked cards from the likes of Gainward, Palit, PNY they all appear to have a single fan. Some reviews comment on fan noise which I assume is because on its own the fan has to work harder than some of its more gaming orientated counterparts which seem to come with multiple fan set-ups, again I assume as they generate more heat.

       

      So am I better off sticking with a base clocked version to keep the temps down, or should I be less cautious and consider OC versions to benefit from more fans, assuming that doesn't just mean even more noise!

       

      Currently my front runners are the Gainward GTX 970 or the Gainward GXT 970 'Phantom' depending if I go OC nor not. Any first hand experience with these would be gratefully received.

       

      Thanks in advance for any and all help.

          Well for years I have overclocked GPU's and advised overclocking, but with the advent of Maxwell 2 and the current version of Premiere there is no advantage.  The biggest factor until Maxwell 2 has been the memory speed, nothing else seems to help CUDA MPE processing.  For instance I am overclocking my GTX 765M by 50% with absolutely no heating problems;  But with my new GTX 970 with these nVidia specs:

          GTX 970 Memory Specs:

          7.0 Gbps Memory Clock

          4 GB Standard Memory Config

          GDDR5 Memory Interface

          256-bit Memory Interface Width

          224 Memory Bandwidth (GB/sec)

          There is no current way to run it at 7.0 Gpbs, it is somehow locked at 6.0 Gbps.  Even adjusting the memory speed to 7.4 Gbps the CUDA assisted exports from Premiere stayed at 6 Gbps (GPU-Z and EVGA's OC Scanner both confirm this.

           

          Remember that this is today's hardware/software.  nVidia's Maxwell has a new SDK and when Adobe takes advantage of this major performance improvement it will pay off significantly.  Buying a GTX 970 or GTX 980 is investing heavily in the future, it will not improve performance over the current GTX 700 series.

            Thanks for your reply. I did read some threads about a compatability issue with Adobe and the new maxwell architecture and though I have seen a work around in a thread on here to boost performance, as long as I am getting better performance than our currant line up of gpu's which are headed up by Quadro k2000's for the lucky few and the rest stuck with software only (hence the need for new workstations!), I am happy to wait for Adobe to fix the issue.

             

            As it doesn't sound like there is any real difference between the types of cards the old advice I was given may well be obsolete in light of the new technologies so I will have to look again at the various different brands and see if I can find any other aspects such as warranty that might swing it one way or another.

             

            Thanks.

              Actually that was Harm 's final  selection criteria.  I just had an excellent experience with EVGA on replacement.

                Indeed I did read that from a link on this forum.

                 

                I have heard good things about both Eva with their ACX fans, Asus with their direct cooling and windforce with their triple fans.

                 

                Personally I have only ever bought Quadro cards so this is new ground for me. I was impressed with the customer service at Gainward when I asked them some questions hence my earlier comments about them. However I have found a standard Base clocked GTX 970 from Zotac the has dual fan which seems like the best of both worlds - lower heat and better distribution. I am still a bit concerned about a single fan card and noise it might make so I guess I will weight that up against the Gainward 970 Phantom which has dual fan but is over clocked - or at least I think that is what they mean with the slightly higher base and boost numbers.

                 

                Thanks again for your reply.

                  Ed2149,

                   

                  If you are still planning on sticking GTX cards in Dell Precisions, you would probably be best served by selecting a reference design card, where all hot air exits the back. Funny thing is, I'm typing this email on a T7610 with a EVGA GTX 780Ti ACX card installed , so I can assure either could work. If I had the choice with a Dell build though, I'd choose the reference since that is what the pretty well engineered Dell Precision cases were intended to use. (sidebar: For anyone reading this that has a high-flow case and a single GPU, by all means go with a non-reference design - it will definitely cool better.)

                   

                  Regards,

                   

                  Jim

                    Hi Jim,

                     

                    Thank you very much for your comments, especially good to hear from someone with experience of these card in Precision cases as indeed I am planning on putting the card in a Dell Precision - either T3610 or possibly T5810 budget depending.

                     

                    As before I had been told it was better to stick to the reference designed options to keep temps down and as I have been looking at the cards on offer I have also noticed that some of the modifications done by brands for the gaming market often increase the size of the cards to accommodate additional cooling systems, and also in some cases change power connections.

                     

                    As I need to ideally get a card that can be served of the standard dual 6 pin config the reference cards come with as that is what is what is on offer from the psu, and I also need to be careful the card fits the case, something I find harder to work out as I have not got a case to check exact measurements. I think the reference route you point towards is probably the best option, esp if as you say this is what the systems would have been designed to work with.

                     

                    There seems to be a good selection of these at a very good prices with not much between the Palit, Gainward and PNY options as far as I can see.

                      GTX 970 or GTX 980...will not improve performance over the current GTX 700 series.

                       

                      But will it keep up?  Given the larger memory bus and increased cores, I would expect the 780 to surpass the similarly priced 970, no?

                        Not by much and so far the 900 series shows further potential than what is being used. HDMi2.0 with lower power and heat makes the 970GTX the better choice really at this point.

                          Have you run or seen published proper comparison between the 780 and 970?  (Meaning everything identical, changing only the card between runs.)  I'd love to see some numbers.

                            Not yet no. I have just released benchmarks comparing the 980GTX and 780Ti.

                                  I am not Eric but with our PPBM8 GPU assisted MPEG2-DVD encoding benchmark and Adobe Premiere 8.1.0.81.  Here are my results.

                                   

                                  GTX 780 SC = 27 seconds   (EVGA p/n 03G-P4-2783-KR)

                                  GTX 970 SC = 27 seconds   (EVGA p/n 04G-P4-0974-KR)

                                   

                                  A tie.

                                   

                                  This timeline is loaded with MPE assisted effects and features and with CPU only averages about 500 seconds for export.  Now with the GTX 780 SC, I can raise the memory clock from the basic 1500 MHz to 1750 MHz and then the GTX 780 SC runs the benchmark at 24 seconds.  I cannot change the memory clock on my new GTX 970 Maxwell version 3 chips.  If anyone has different Maxwell results please let me know.

                                   

                                  Would I suggest going with the GTX 780, NO!

                                  1. It draws more power
                                  2. It does not have HDMI 2
                                  3. It does not have future potential performance increases that Adobe may take advantage of in one of the next releases of Premiere.

                                   

                                  P. S. Put both in a system and the PPBM8 GPU acceleration drops to 14 seconds.

                                   

                                  On a non-DVD export our H.264 timeline without GPU assistance is ~ 900 seconds (this test is not part of our PPBM benchmark) and with either GPU it is ~ 88 seconds.  Adding the second GPU only drops it to ~ 80 seconds.

                                   

                                  Eric, I have looked at your immense thread on Haswell E and also cannot find it, can you narrow it down a little

                                    Look on Page 1 toward the middle and you will see the 5960X@ 4.5GHz with the 980GTX card. Back at the beginning of the thread the benchmarks were done with the 780Ti.

                                      Thanks, guys. My only concern with the 970 is that a LOT of folks are reporting a strange whine at high loads.  One user even measured it at 92dB next to the case!

                                        I have not seen that at all on the Zotac cards we get. Keep in mind Geforce cards are going to have differences as far as manufacturing because of the different manufacturers and components used such as the fan. You will  also have different video bios for the card.

                                          No problem yet with my 970, but if you notice this is not a reference cooler it is an EVGA design "ACX" whatever that is.

                                            Thanks, guys.  The "ACX" model is a bit pricey (and out of stock at Newegg).  But they do offer a Zotac model that doesn't have the user complaints of a whine under load.

                                              I have the Asus version of GTX 970 and don't have any noise or whine.

                                                The ACX is probably out of stock much like the rest of the popular vendors oc models with custom coolers. Mainly you will see a bunch of the reference design cards in stock for now. These 970s really are going like sweet candy, and it's the holiday season coming up. Soon it may be even harder getting a good card. On OCT seems most people going for either the MSI Gaming or the Gigabyte G1, the latter with a higher focus on cooling and less on noise. Seems both can hit 1500 for most everyone and some people even get 1600 Mhz. 1950-2000 Mhz for memory speeds as well.

                                                 

                                                I am experienced with OCing gpu Bill but I will try my card tomorrow or the day after. Was spending a lot of time testing my memory last few days and spent all night on my cpu today. Still gotta see what kind of clock I will run, I think 4.2 Ghz is gonna be most efficient though. The thing you were saying though, is there a difference to regular memory clock speed on your video card when cuda cores are involved? Or is your board simply locked at 1600 mhz... I know that the Zotac cards are apparently voltage locked and people can't get too much OC out of the Asus cards either.

                                                  I guess I should have been a little more specific on my overclocking.  On the GTX 970 I can set the memory clock at 1750 MHz easily but when you run it under load the clock only runs at 1500 MHz.  This is all done with no overvoltage or no other clocks adjusted.  That is my procedure that works on any earlier generation (GTX 400, 500, 600 and 700 series) boards that I own.  Here is what I see GPU-970.jpg

                                                    I just got to 2000.7 Mhz Bill. Actually at stock speed I was having the rated 1753 Mhz on my memory.

                                                     

                                                    You have the 780 and 970 in the same system don't you? Do you have settings synchronized? It must be something throwing it off. I know that some cards are having some limits or others, example like the Asus 970 that only has the 8 pin connector so no matter what you're going to be limited with how far you can push it, but your memory speeds just seem wrong!

                                                     

                                                    Edit. Going to call it a night now, Got some minor artifacting with gpu clocked at 1480 Mhz, 1475 was fine with the 2000 Mhz memory clock. This was done without raising the voltages of course, I might try if I get another 50 Mhz out of the memory tomorrow but I frankly like the round number. I've also read some people getting interesting results slightly undervolting with a minor overclock. Of course this is all just for the synthetic benchmarks really. I actually ran fine on higher clockspeeds with the metro benchmark which is the only game test I can run from here now, but Fire Strike was a bit harder to play, hehe.

                                                    ps. What's with all the moderating required on these forums, is this purely a check whenever you include links in your posts? It seems like a big nuisance to have posts 'on hold' all the time...
