Also, are you using a multimeter? The DMM was mentioned earlier, but if you are reading precision voltages, you will never get accurate results.

It has been shown with EVGA cards that voltage bumps do very little to help with over locking on these cards. I can get 1580 on my s without adjusting voltage at all, and verifying it with aa multimeter.

i ordered the reading tool!


but shouldnt it overclock more than 1440 with a 71 asic?

i flashed a kingping bios and didnt do much for it, i wanted to get a kraken for it but with this type of OC whats the point

any bios you suggest ?

Silicon lottery applies. You could have a 90% asic, and if something else (that isn't the core itself) holds it back, you aren't going to be able to overclock well.

Asic strictly applies to the core itself, nothing else on the card. The possibilities are unlimited to what could cause a bad overclock.

If the K|ngp|n version of the classy bios didn't help, then you may try getting one from another user to test.

There are plenty of people with higher asic cards than your, that can't overclock well, and at the same time there are people with 63% ASICS that are blaming higher asic cards out of the water. It's all a lottery.

What kind of memory overclock are you getting?

When you overclock, you should go strictly core first and find its limit, then try memory so you are sure to get a clean overclock.

seems rare for a 14 phase 71% asic card....its a bit disheartening i cant do anything with it ....feels that i got what i got and thats it ...my old 980ti SC did 1550 @ 1.212 with 67% asic ....this one wont even touch 1450

only adjusting voltage won't increase the clock speed (if i am understanding you correctly). all that does is add heat and i cannot stress enough how temps matter more than anything else with maxwell; a 14c difference (48c - 62c) allowed me to gain 25Mhz.

if you have flashed any bios from a forum "expert" reflash back to the original(s). i didn't run across any bios (aside from the OC BIOS CLASSY 980Ti on kingpin's forum) that didn't seem to give me more problems from the half dozen or so i tried; the only difference w/KP's than LN2 bios is a higher max fan speed. well, i'll contradict myself slightly and suggest using KP's.

don't think ASIC will be relevant to clock speed - it's relevant to voltage - you will be limited w/whatever that chip can give. just leave the voltage alone and work on just the core speed. i understand and got disheartened also seeing G1 and SC cards hit 1550 - 1600 as i struggled to get past 1500-1505; esp. after it boosted 1405 out of the box and thought 1550+ here i come! and the vram on my card was even more disappointing, having problem getting 7850 - which leads me to:

don't OC vram yet until you spend more time OCing the core. to be honest i am bias against vram OCing unless benchmarking. i know i know i know but i don't think its worth it for gaming when you consider it will hold back your core speed most times. but my bias doesn't need to be your's after you found the core speed "sweet spot"

to spare others from me posting a wall of text - get a probe it and DMM! that is the most accurate manner to measure vcore. though i am sure you saw 1.212v in AB or PX, i have reasonable doubt it was actually that low for 1550 on your SC. i'd like to see someone solder a wire to the vcore pin on the reference buck controller and see what they get.

oh? as i tried to post w/o being too wordy i see Scarlet-Tech ninja'd . . ninja.gif

TL:DR

leave the vcore alone - increase core speed @25Mz until crash - increase vcore .006 (or the smallest) try again.*

get a DMM.

i repped both of you guys ! thank you so much for the help, they are sending me a different one from amazon. I ordered the EVGA probe it tool too and i have a DMM!


i might order a kraken and a h55 for the Classy and test my luck with the new one ! what do you guys think?

It's always worth a try. My 980 KPE would not run on stock cooler, but overclock to 1580 on waterblocks.. Temps can make a huge difference.

pretty sure @KickAssCop has/had that kraken/H55 set up . . . think you need a shim.

i did this on a old 780ti EVga i had ....do i need to mod the classified too much?

all i bought for my old one was the Kraken a h55 and some copper sinks for the ram!

what do i need for the classy

Do not take the heat spreader off of the card of you take it off, the vrm will have no way to dissipate hear. You should have the h55, the nzxt Kraken bracket (with fan) and then a ps3 copper shim (found on Amazon here: http://www.amazon.com/Playstation-PS3-Copper-Heatsink-Repair-Sony/dp/B007REGGFK/ref=sr_1_1?ie=UTF8&qid=1447016481&sr=8-1&keywords=Ps3+copper+shim)

You should not need to get copper heat sinks for the van if you leave the heat spreader in place.

EK universal block should work well with classy if you don't mind paying for a little more.

found this ...gonna get the washers and the h55! i have a cougar fan ready for the h55 too!

looks good ?
