Gtx 560

yeah i was just at tpu when i seen this new soc card.Just like the early 70's again stuff is just getting slower ?.

Wondering if you can help. I have just recieved my MSI GTX 560 Ti Twin Frozr II OC and I have downloaded the MSI Afterburning 2.10 Beta 7. I have begun overclocking and currently sitting at 960 core with stock voltages, however I was wondering if it is possible to unlink the core and shader clocks as they are linked by default? Also, is there a max "safe" clock for memory and core voltage?

Thanks.

[cowie]

no unlinking of core/shaders with these cards.
Max safe clocks are relative to temps and voltage.
Good job so far

I need to do some tweaking though, ran OCCT and hit 6 errors after 10mins of stress testing. Want to play some Crysis 2 now anyway, quite supprised actually, this thing can handle Hardcore settings on the Crysis 2 demo with a FPS rate of 45-70 running at 1920x1080, better than I was expecting!

This card is fantastic value for money I must say. Double 3DMark Vantage scores compared to my old GTX 280, turning down Crysis 2 Demo to Advanced settings, as I couldn't see ANY difference when comparing screenshots, the frame rate is now 60-110 FPS. Excellent! I also managed to overclock the card to 1050MHz core, just as a quick test, however it seemed to require quite a lot of voltage, and the performance gain wasn't very much, in fact it was worse on FurMark benching which was strange, maybe it didn't like the high clocks. I think I will just stick with 960MHz, might push for 980, or maybe even 1000MHz. I have now got 960MHz stable with 1000mV compared to the stock 1012mV, it refused to stay stable at anything lower. After I get the perfect Core clock, it’s on to memory!

Temps are awesome too, idles at 27-30C, and tops out at around 54C under heavy gaming/benching. FurMark/OCCT however, managed to top the card out at 82C at one point, rather scary considering! My Corsair Obsidian 800D isn't exactly the best case for ventilation though, especially considering it is mostly water-cooled. Enjoying this card thoroughly though, only purchased it as a stop gap until the GTX 680 is out, beat my expectations!

GB has just realized 1GHz it's not easy, LOL. They have moved to 950MHz now, and I guess this the end of 1GHz SOC.



Gigabyte Intros GeForce GTX 560 Ti Super Overclock Graphics Card

LOL, Gigabyte fail

I'd be surprised if anyone got a stock card that doesnt manage a 950 Mhz overclock.

950 Mhz looks easily doable on almost every GTX 560, going over that is completely random, and increasing the voltage doesnt do anything to improve stability.

It makes no sense paying extra for a 950 Mhz overclock on these cards, they will get to that much regardless of which one you buy.

[p2501]

Good thing that I grabbed one of the 1000MHz cards before they disappeared... =)

[NathObeaN]

Well I settled with 950MHz as I had a few mild stability issues on 960MHz, increasing the voltage to 1025mV allowed me to stay stable at 960MHz but I am just going to stick with 1000mV @ 950MHz. I also overclocked the RAM straight to 2400MHz, could possibly get more out of it but it's not worth the little performance gain to push the RAM chips too far imo.

Hi Guys,
I picked up two Gigabyte 560 OC cards on release day. My first card is 1.000v and my second card is 1.012v.

I've been following the thread, but haven't really done much with my cards. I tried OC to 1ghz on stock and I get a GPU crash if I start any stress software.
It recovers, but the OC is removed. I also tried increasing voltage to 1.15v on both cards, and go for 1GHz. Same result. Instant GPU driver crash.

I have not tried any other OC and I have not tried any undervolt yet.

My two cards DO NOT have heatsinks on the memory. They also do not have a heatsink on the mosfets. They only have the giant windforce2 cooler.
There isn't even any possible way for heatsinks to fit under windforce2. Clearance is much too low - maybe 2mm space between the fins and memory IC's. Can anyone with Gigabyte OC cards confirm if they actually have heatsinks? Should I send my cards back to GB because they are missing?

[cowie]

Mine giga oc(900) card has a small hs on the mosfet area.the ram runs cool and has air flow over them so its not necessary to use heatsinks(if you could fit them that is)
Turn the fans up and start with small increases in clocks,in sli they will run hotter so take it slow.
the oc hs for vrm is smaller then soc card look closer.

Ok, I will check again tonight. One thing I noticed is there seems to be quite a bit of space between the heatpipes and the base plate on both my cards. Contact is not 100%.

Full load with furmark using displacement mapping and xtreme burn mode with AFR1 brings my gpus up above 90C!!! Stock voltage and stock speed. My ambient is ~29-30C.

Three questions:
1. should I try to fill the gaps between the baseplate and heatpipes with TIM for better surface contact?
2. How is the TIM on the core? should I replace it with some X23-7783d?
3. I've been using evga precision for my gpus, instead of gigabyte oc tool because it incorrectly identifies my cards as GTS 450's... Is that ok? I've been using nvidia inspector to change voltage. Is there an all in one tool that will do it all?

Lastly,
Gigabyte SOC is different!!! It has a photo cap on it for super clean power.

The real secret to the SOC's ridiculously high clock speeds, though, may be the component pictured above: a Proadlizer film capacitor from NEC/TOKIN. I don't believe we've seen one of these on a graphics card before. It sits on the back side of the card right between the VRMs and the GPU and memory chips, purportedly providing "excellent noise absorption performance" and "high switching frequency."

It also has 6 phase power.

[cowie]

1 i would not turn a screw if you are going to send them back
2 tim was applied very well on my card the change did not make a big differance (after a week or so)
3 lastest afterburner

I know the soc has the best hardware for any 560 i'v seen in retail so far,they were not much higher in price either..

[p2501]

zoson, judging from from the card I've gotten the TIM on the heat spreader is not too bad, but if you don't have good contact you should remount it anyway. Other than for example Gainward you won't void your warranty I think.

The card itself really is a solid piece of engineering but the HSF isn't that well built, it couldn't keep my card from overheating when running Furmark at it's stock setting of 1000MHz@.98v. I changed to a Thermalright Shaman with IC Diamond and now all is fine, folding now @ 1075,1.05v 2505 on the memory. Furmark still isn't stable above stock and voltage isn't helping that either. But that shouldn't matter right, we aren't buying card to play Furmark, right?

Concerning the OC tool from GB, well it's chunky and not really useable. Get the latest MSI Afterburner or NV inspector and you should be good, but you'll need the GB tool to change memory volts.

I didn't find any info yet on advisable memory voltage in the long run.

Yep , oc your cpu get a nice performance

[zoson]

Bumped my voltage on both gpus up to 1037mv and it allowed me 933mhz core 1866mhz shaders.
Memory bumped up to 2200mhz. Looks good so far!

I also took one of my cards out and found the mosfet heatsink. it was hidden by a row of caps so it was invisible while installed!

I see a lot of people getting 2400mhz mem, so I'm going to try that tonight. I heard, though, that GDDR5 has a type of ECC, so it's possible to get a very high clockspeed, but actually have worse performance. Is that true?

[NathObeaN]

Well I had to downclock the card a bit, couldn't run it at 950+ without unreasonable voltage increases to get 100% stable. By that I mean just after an hour of furmark it would crash, and it froze once or twice in the Crysis 2 demo.

I have now clocked it down to 940MHz on the core and 2200Mhz on the RAM running at 1000mV. Now it passes over an hour of furmark and doesn't encounter any issues at all. Still not a bad overclock, factory OC of +60MHz then my own OC of +60MHz on top, using 12mV less power than stock .

[NathObeaN]

Down and Down we go! I started off at 970MHz, thought I was pretty safe with an hour+ test on furmark, 3DMark 11 and Vantage, Heaven benchmark, NVIDIA demos etc. But no. I put on BFBC2, and on the first level in the dark, these strange white squares started to appear, from experience I know it is related to the shader clock being set too high. This really annoys me because my core is running fine, but because you cannot unlink them, I have now had to downclock once again to 925MHz in order to fix the shader problems. Before long I will be down to the stock clock for this card at 880MHz! lol Still, I might be able to undervolt it a little more...

[NathObeaN]

Scrap my last, I was able to get rid of the shader problems by bumping the voltage up a notch.

Now I have found 3 possible varients that don't show shader glitches:

925MHz @ 1000mV
940MHz @1025mV
960MHz @ 1037mV

Of course I am aiming for the last one, so it's back to the furmark drawing board for an hour of stressing, bit worrying though, xtreme furmark, with all the settings to the max, and it's hitting just under 90C at the last settings. Ouch. Games rarely go above 60C though so it's not a major concern, I just don't want to make a habit of running furmark.

On another note, how hot do the RAM chips get when bumping the clock rate up, I was able to bump them up to 2550MHz before any artifacts. That would make it 5100MHz effective clock, yet the highest card out there, the gigabyte SOC is only at 4590 effective, which would translate to 2295MHz. So, is it safe to overclock that far, and how hot do these ram chips get, I have an MSI Frozr II OC, and I believe it doesn't have any RAM heatsinks?

[NathObeaN]

Does anyone else get a slight "load judder" when playing BFBC2? I was trying out the campaign and as I was walking it was juddering every now and then, and if I walked back and forth over the same point it would judder everytime I passed that point, which obviously means it's loading something, but it shouldn't judder every 10-20feet I walk...

I tried underclocking the card but it still does the same thing. The only thing that got rid of it was to turn the settings down which makes me think it is either a game or driver bug, could someone else confirm please?

EDIT: SOLUTION FOUND! Only... it's a disappointing one. It seems BFBC2 has a glitch with i7s/Hyperthreading. Turns out, if I untick cores 4-7 (hyperthreads) in the CPU affinity under Task Manager for the game, the stuttering is completely gone, only the framerate drops by about 20FPS. How could one of the biggest games ever, made by one of the biggest game companies ever, not support hyperthreading?

I still dont understand why people use furmark or any of those static image tests, Furmark stresses your VRM's more than the GPU it self. Your better of looping Crysis warhead ambush at all maxed settings for 30 loops compared to 1hr in Furmark.
