mannitu78 Posted December 18, 2015 Posted December 18, 2015 (edited) hello folks, Hope i can find some advice here. I just bought a EVGA 980 classified, it arrived today. The sender was some kind of friend of me who often supports ma with new hardware because he usually buys 2 new card every year and he is somehow into overclocking, not professionell but just for fun with air cooling. They price for the card is 560eu atm and i paid about 140eu less, whick made me quite happy, the card looks almost factory new, he is already running a 980ti now. So i was very excited, installed the drivers, took out my old GTX 680 (which has a brandnew morpheus cooler which i want to stick on the new 980), made some benchmarks to test the card, only the valley so far. Results: Core works fine. i put + 120mhz on the core which gave me about 1550mhz actual boost clock and it seems tun run (there is no bios modded as far as i can see, voltage is 1,212. What disappointed me a little bit, the memory in the classy is running at 3500mhz and supposed to work wit at least 4000mhz (8000mh effective), thats what i read in all forums and discussion. Yet the card already produces tiny artefacts at 3850/3900mhz. Seems like i cant go further then 3800mhz stable. The question for me now is: Is this card fucked up or can i manage the problem? I think it might be the vram is running to hot maybe or doenst have enough voltage. I am planing to put the Morpheus on it anyway and want to stick own VRAM and VRM cooling pieces on the chips. ATM these chips are cooled by a kind of thin plate, which covers all the PCB and cools every part. I dont know how good that cooling is. Problem ist, if i take this plate off and stick my own cooling on it and the memory will still make problems at 1950(3900) mhz, i will ruin the guarentee, because the card was bought this year an still has more than 2 year warranty. What am i supposed to do now? I really like the card, but this memory thing pisses me off. I was palning to get real good results with my morpheus cooler and my self made copper heatsinks for the memory chips and was planing to use the EVGA Mod for higher voltage somehow in the future. Is there a chance the memory will get more stable with increased voltage or better heatsinks? What do you think of the standard cooling plate? Thx and greetings from germany @Waco: sorry, maybe i didnt make myself clear enough, ofc it runs proper at stock clock. Stock clock for a gtx 980 memory ist 3500mhz. But Stock clock is not the point.

Waco Posted December 18, 2015 Posted December 18, 2015 It should run properly at stock settings. It might be worth getting in touch with EVGA to confirm the stock clocks, and if they're really supposed to be higher, RMA it. Share this post Link to post Share on other sites More sharing options...
Gremlin Posted December 18, 2015 Posted December 18, 2015 RMA is not transferrable from owner to another if it is sold by the owner I believe.. ? Share this post Link to post Share on other sites More sharing options...
SpikeSoprano Posted December 18, 2015 Posted December 18, 2015 If the card runs fine at stock clocks an rma won't help. OC'ing the card is a bonus not a given, so it is running fine as far as the manufacturer is concerned. Share this post Link to post Share on other sites More sharing options...
bp9801 Posted December 18, 2015 Posted December 18, 2015 Sometimes components just tap out at a specific speed and nothing you can do changes it. Just luck of the draw with the parts. Share this post Link to post Share on other sites More sharing options...
RedFury77 Posted December 18, 2015 Posted December 18, 2015 Pull the cooler, how would evga know if you did it anyway. It runs fine at stock so you won't be rma-ing it anyway and even if you do for some other reason, just put the stock cooler back on. Just keep all the thermal putty pads stuck to the cooler. Then you could take a look at the vram and see what brand and number they are and maybe see if you can get a better idea of what their max speed might be. From what I quickly saw, most 980 cards get +300 and some as much as +500 so it sounds like you are in the ball park to me. The stock 980 I had couldn't overclock at all, hell it would overheat and throttle with stock clocks and the fan set to 75%, so I'd consider yourself lucky.

mannitu78 Posted December 19, 2015 Posted December 19, 2015 (edited) so obviously no one with a 980 classy here i can comprare results with? Edited December 19, 2015 by mannitu78 Share this post Link to post Share on other sites More sharing options...
SpikeSoprano Posted December 19, 2015 Posted December 19, 2015 RedFury77 just said what his would do, I'd say that was a good comparison ! Share this post Link to post Share on other sites More sharing options...
mannitu78 Posted December 20, 2015 Posted December 20, 2015 (edited) do you really think they dont get it when i pull it off? Theres only the cooler with 4 screws. Im ok with that. Next step is that aluminum plate for cooling mosfets and VRAm. Its got pads under it. YOu dont think, there is some kind of seal or sign they check? It would be so easy, they would have to give warranty to any mod, as long as he just puts back the plate. by the way, the memory runs with 1950/3900 now stable. i tried to switch the bios to the version with red LED, i dont know why, but the memory is stable now with that overclock. I didnt try any further yet. Its not supposed to be healthy to complete Benchmarks while they produce artefacts, is it? The memory in the Classified is Samsung which is specified for 2000mhz. The only explanation i have is that it doesnt get enough voltage, in the "manual" bios even less than in th "OC Bios"...but thats just a guess.
