Core clock vs Memory Clock?

[Oshtro]

I will be adding another PNY GTX 980 to my pc to put in SLI tomorrow. Afterwards I plan on benchmarking with 3DMark and Unigine. I previously ran the single 980 on Unigine at +200MHz core and +500MHz memory clock and received a score of 3198. Today I pushed my memory clock to +600MHz(haven't tried any higher other then +700MHz which failed) and then re-overclocked my core clock up to +215MHz(+220Mhz failed) and then ran Unigine. After rerunning I received a score of 3302. As I don't want to spend all day tomorrow fine tuning an overclock I would like to know if anyone else has any extensive knowledge of mixing the two for the best performance gains overall. Should I push my core clock until failure and THEN the memory clock or is this the best way to do it, without the fine tuning yet(which I just don't have the time for right now). Thanks for any reply's regarding the topic and all my pc specs are listed below.

Definitely push the core clock more than the memory clock

I was really thinking the memory clock might help more by being pushed the furthest but I got a little bit of time left before work and already know my core clock will go to ~ +240MHz so I can try it out real quick.

push core clock as far as it will go first

then go memory after

You want a balance between the 2, Like I have a Core Clock of 1387MHz and a memory of 2008MHz on both of my 770's

After you've found the limit of each separately, then stress test with both overclocked. If your overclock fails, then reduce memory overclock first and rinse/repeat until your card is stable.

I get better OC when i push the memory clock. I don't know why, but my card (gtx670) cannot OC very well with just the core clock. 
Of course i got the best OC when i pushed both.

Ok, so I pushed the core clock to +240MHz and it fails at even +250Mhz memory. Plus like theodoro said I am apparently getting a better oc with the memory pushed further anyways cause i had a higher fps with the +215/+600 I was running then the +240/+250 which even failed.

well then try it how you originally had it and see if you get the same score

there is a good chance it was just margin or error and now you have some program running in the background that reduces your score a little

Are you talking about the original 200/500 I had vs the 215/600?

1592MHz core/4005MHz mem

 

 

 

+215MHz core clock/+600MHz memory clock

1607MHz core/4105MHz mem

 

 

I made sure nothing other then RealTemp and MSI Afterburner were running in the background, dont know how I scored higher the first time with Spotify running as well. Either way here are those two scores compared.

Well as you can see from those two benchmarks it does help to have a higher core clock and mem at the same time...

[Oshtro]

Yeah

Yeah I see exactly what you mean, I will try to push my memory clock on my 215/600 as far as it can go and then benchmark. Then ill start looking into somewhere around a 225-230 core clock.

ok sounds good

[Oshtro]

Yeah

Apparently +215MHz/+600MHz is gonna be right at about my sweet spot for this card, but of course I will have to do some reoverclocking tomorrow when I have both cards but I do understand exactly what you meant. I guess this card just benefits slightly more from a higher memory clock rather then a slightly higher core clock.

 

 

+225MHz core clock/+400MHz memory clock +450MHz was unstable)

Ok cool

OCing is awesome

[Oshtro]

Ha yeah, if you don't oc then what are you doing. I cant wait to get my second card tomorrow and I will definitely be submitting my SLI score to the Unigine thread once im finished fine tuning in my gpu's oc. Hopefully my second card can handle the 215/600 so itll make oc'ing easy tomorrow.
