    I have never had an experience where vram speed affected gpu oc. And I have owned quite a few gpus over the years.

    Memory OC did affect GPU core on my 560Ti, though it could be instability that wasn't ironed out or an anomaly. I couldn't use 950Mhz with 2100+Mhz on memory, but at exactly 2100Mhz it would be stable. But I could use 902Mhz with 2376Mhz on the memory with ease.

    Even my G1 is a bad memory overclocker I think, though I've only tried OC at stock voltage. I never bought the G1 thinking its guaranteed to be a high clocker because gauntlet sorting. I wanted the backplate, the 4 heatpipe heatsink, the cool windforce illumination logo. Anything on top of that was a plus for my expectations.

    Also Heaven benchmark gave me 1400 (Not Valley). Curious if anyone ran Heaven Bench as well, Ultra Textures, Extreme Preset, 1080p. Want to see how this score stands.

    My Heaven score is 1571 with card running at 1500/8000.

    Then why are you stuck @ gpu 1150mhz? Lower vram OC and Im 100% sure you can do 1200mhz on core..

    So I tried volts to 87 and power limit to 110 with +160 (around 1592Mhz boost), was not stable. +140 also crashed at 87 I think. It may be because 334.80 is a bad clocker as someone with G1 posted back in the driver thread.

    So far, the 100% stable settings are +120 core, +325 memory, which leads to boosts of 1520/7822Mhz. Thing I'm happy about is, its at stock voltage. Unless I can hit above 1600Mhz with voltage increase I think I'll stick to this.

    Also forgot to report ASIC quality reading, 72.3%. Fairly average I'd say.

    Also probably point to note, gigabyte's fan curve is too aggressive. And I didn't expect the Windforce illumination to be so strong. Its about on par with my HDD LED in the 400R case which lights up brighter than a christmas tree in the dark.

    Nope 1150 is the max stable at stock volts regardless of vram speed. 1189nis max with added voltage regardless of vram speed. Voltage is the deciding factor in gpu speed.

    Dunno about you then, but I can OC further with lower vram freq. same with my old 570gtx or 580gtx or 250gts, dunno about 8800gts or 6600gt anymore.

    Yeah it's crazy, I get 80 average FPS on Shadow of Mordor bench, at the very maximum settings! During actual gameplay it ocasionally stutters a little bit, nothing too annoying though.

    BUT I'm waiting to see how it behaves with Evolve. I tried the alpha for this thing in October and not only the sheer fun and excitement of the gameplay blew my mind, but the game also almost blew my poor GTX 560. :p It did only 20-30 FPS on the very lowest settings.
    With my new toy I should have 60+ FPS easily at higher-than-minimum settings :D
    The beta for it comes out in January, I strongly recommend you guys participate if you can. Haven't been this excited and impressed by a game's fun factor in years.

    With my previous GTX 780's VRAM oc had zero correlation to GPU oc. Adding extra voltage gave just peanuts in terms of gpu oc but it did make the card run hotter and noisier.

    I had 2 580s myself. Highest stable oc was 878 regardless of vram frequency. Same thing goes for my old 680 sli setup. 1280 maximum boost. 6ghz 7ghz 7.2ghz did not matter. Maybe low end cards that you mentioned might be different.

    The mem controller matters and yes, it is being influenced by core speeds. He's right, and apart from the 6600 I don't really see him mention any low end cards.

    That is not my experience. I have owned many cards and the vram speed did not influence core speed 1 bit for me. From 2 295 all the way up to 2 780ti. I should of said lower end to midrange cards for the older cards. Had a 6600gt for a couple weeks replaced it with a 6800gt because I was not happy with the performance. 250 was a fake 200 series card as it was a g92 retread. Older cards not really sure of as I do not remember.

    It may be your experience, that's ok, but it's common experience nevertheless.
    Newer cards, starting from 4xx to the current series, definitely had this influence.

    I had a 480 too that was not affected by vram speed either. Heat was the determining factor as the reference ran very hot.

    I figured out why my 970 is a bad memory clocker. It has Hynix memory lol. Not samsung like the one in the review, or all the other 970s out there. I kinda feel deceived :(

    Dropped Core to 1300/1514, 1520mhz boost crashed a game. This is how I do my stability :p no useless stress tests, just ramp up what I think is right and play a game, wait for it to crash, ACU crashed after 2 or 3 hrs :p

    Hynix is a very good brand. Elpidia is the worst of the 3.

    Ive also had no difference with vram oced vs stock on core clocks. as far as i can remember, 8800gt, gtx 470, 2 580 lightnings, both of my 680s and this titan

    Hmm maybe feeling deceived was a poor choice of words. Though I would have liked Sammy RAM, but yes by no means it makes it a bad purchase at all.

    So my final overclocks for this at stock voltage seems to be 1514/7658. I think its okay for AISC 72%? I could squeeze a little bit more out of memory but cba.

    I did try cranking voltage to +87mv and +208 (1600 boost) on the core, doesn't seem stable. I think I'll settle for these now, and I have concluded that 344.80 is a bad clocker overall from several people, havent tried 344.75 yet.

    570 had samsung, I could do 200 -300mhz on that but later it started to fail (~2years). And it died at end because of vram even @ stock 2000mhz, had to downclock to 1900mhz towards the end and it still failed..

    580gtx had hynx, as soon as I touched vram @ 900mhz gpu OC it would TDR, leave vram stock I could OC 900mhz np. Saw that especially in BF3 mp, Rift mmo (lots of streaming by both).


    Same thing now by 780 & hynx, higher gpuv doesn't help much, 100-130mhz seems the max I could do at higher 1215mhz gpu, 1.187v or 1.178v.

    Anyway higher vram OC almost always hindered gpu OC here (and nope your so called "lower end" gpus dont make a difference), I always test this in real more demanding games. I personally dont take generic benchmarks for granted, even if its stable few hrs of testing it. Then there is driver, some have more tight vram timings and that can lower vram OC too.

    I had a 6600gt it was midrange at best. It was quickly replaced by a 6800gt. A 250 was dated on release. It was commonly referred as a fake 200 series card as it was g92. As for the 580 570 they were high end on release. If a person kept them long enough they were lower end performance compared to newer cards. All my cards are meticulously tested to run at the clock speeds I end up with in all situations not just in a select few things like you are inferring that I am doing. From 260 all the way up to gk110 clock speeds were not influenced by vram speeds. Although I do mod all my bios for the power target 106% is pretty awful. Its modded to 120% so I do not get any downclocking at all.
