is my gtx 780 gddr5 memory decent?

[misfitkid86]

i was looking into the memory on my 780 classy and noticed it wasn't samsung or elpida, but it's hynix. any good? better or worse than samsung, and should i not overvolt on it? thanks for the input!

elpida is the crappy stuff. hynix and samsung are the better ones with samsung generally being slightly better. elpida has trouble getting over 1500mhz/6000mhz effective... while hynix and samsung usually get up to 1650/1700mhz without issue.

rad thanks! don't suppose you've used the gtx classified controller? i want to overvolt my 780 classified but don't know wether to keep it on auto or take that off and bump voltage to 1.20?

Hynix is well regarded OEM. The 780 will have headroom for some overclocking. For example, check the overclock on a Gigabyte GTX 780 OC card.

oh yeah, this thing has a 14 phase power design and is already overclocking a bit, just need a safe bump in voltage to really cap it off. i just havn't ever used this tool so i don't want to screw up one of the bios's on the card.

rad, i'm thinking i'll take off auto voltage and set it to 1.19 or 1.20, i'm looking for something decent but won't require huge bumps in fan speed, when i put it under water i'll go harder but these fans scream when cranked! i'm i on the right track?

rad thanks!

go to the overclock.net official 780 owners thread and run a custom skynet bios. the evga 780 classified is the go to card as it has all the right goodies on its pcb to be overclocked. its very regular to hit 1.4ghz on a classy. especially if you waterblock it, you can give the core 1.35v and some llc and hit some crazy clocks.

rad, water cooling is the goal but for now it's air, i'm able to keep it at +150/+500 with 1.21v funny thing is is that my 3dmark advance firestrike score was a mere 6500!? any idea why? it wasn't getting hot in the least is voltage still too low for that kind of clock or am i just missing something!? my cpu is a 3570k running at 4.4.

what video card did you have before the 780

asus dcuii 7970

did you do a full manual uninstall of the old amd drivers. you may be having a driver conflict. dont do this if you have amd motherboard and cpu.

so i just hit uninstall after download of amd ccc, i'm on a z77 motherboard. but i'll try this thanks for the tip, might explain why i'm not seeing a huge jump in performance.

 

[nikoli707]

yes if you still have the amd drivers in there that would do it. i personally would uninstall and reinstall the nvidia drivers also. start with the nvidia guide....
http://www.overclock.net/t/1150443/how-to-remove-your-nvidia-gpu-drivers#post15432476

then follow that amd guide, then reinstall the latest nvidia beta drivers.

use a benchmark utility like unigine heaven or valley to check your scores so you know your getting around the performance you should be compared to others.

so i went ahead and cleared all amd/ati files as the instructions said but i didn't do nvidia, you think i should? also the nvidia files i'm using are the latest beta drivers should i stay with the non beta?

 

[nikoli707]

you can check your benchmarks performances and compare to others numbers. its probably unnecessary to uninstall and reinstall the nvidia drivers, i just usually do it anyways to rule out any driver conflicts. most people like to use the latest most recent drivers whether they are beta or whql. you should be getting much better performance now. i also like to use ccleaner to clean out old files and registry edits also.
