GPU overclocking Problems
« on: Thu, 10 July 2014, 10:34:31 »
Hello everyone!

Specs:

GPU: nGeforce 560 TI
MB: MSI z77ag45
CPU: 3770k-i7
Windows 7
CM storm trooper Case
PSU: corsair 750 W
I have been overclocking my GPU and using heaven benchmark. While I managed to get a stable

1087volt (powerlimits not edited, not sure if I should)
950 core mhz
2150 mhz (edited after I got stability at 950)
and temperatures only getting up to 63-64 at fan speed on 75% (Considering a less noisy replacement)

Why is it that my tests on 1.15v, since my temperatures are this low, is basically unstable at even just 975 mhz core and stock memory frequency? I see artifacts, a few spikes and stuff right before a crash in heaven benchmark, usually 40-60 second into the test.

Also, is there any way I can break the fan barrier speed at 75%?

Should I touch other parameters to fix this problem, such as the power limits?

Are there problems in general using 1.15v with this card though I can manage to keep my temperatures low?

Thanks!

starcraft 2 is cpu bound

you can't make starcraft 2 faster with GPU

you need a delidded 4790k @ 4.8ghz for any Useful gain..  those intense battle situations where you get seriously CPU bound..   

the GPU only handles the visuals, which ISN"T the actual game..  The actual game-simulation running behind the scene, doesn't even run at 60fps..

Yeah t4p is right, you need a really nice CPU to properly get the most out of sc2 not really a gfx card. Which is a shame. But even with the best hardware team games will still run like **** once people start having big armies on he high gfx setting

Well I have so many different input on where to put my max temperatures on delidded CPU clocks, so not sure if 4.8 or 4.9 is gonna give much more from 4.7. What are your opinions? Do you mean I should delid a 4770k to achieve better results, like where a 3770k is not good enough?

you don't have to worry about MAX temperatures.. because starcraft 2 won't hit it..


You only have to worry about being "relatively stable"  @ your maximum vcore (not vid)


for 3770,  the max is ~ 1.45vcore ,  use hwmonitor

but .. for 3770, you'd also want to disable Hyperthreading..  This makes starcraft 2 run faster..

Prelim,  we just said graphics don't matter...

BUhhhhhhhhhhhh...   if you're in it for the "eye candy,"  what little there is, i mean.. it's SC2, not the prettiest game by any stretch....     

Then... you pretty much Max out  @ ati 7950  or nvidia 670 level..

Pretty much with anything near or equivalent of those 2 cards will perform IDENTICALLY with Vsync enabled..



If you see benchmark stats where one card has slightly higher average fps, it's because they took the area under the framerate curve,  where a really powerful gpu would have max fpses of say 200, and it'd skew the results..


BUT.... if the graphic card never dips below a certain number say 60 visual FPS, assuming the cpu is keeping up,   THEN you can argue that you're just wasting time with anything more powerful.....



270x is basically a 7870 which is pretty close to 7950,  so I'd say you're done as far as Starcraft 2 graphics go..


CPU is king in Starcraft 2,  it only uses 2 cores.. so you want max clock, AND to disable HT, because it noticeably adds latency to the SC2 queues.

The state of graphic cards is a sad one..

The current bang for your buck card is stilllll the 280x which is just a 7970... and it's $200. it's pretty much been $200 for 2 years.

GPU overclock returns to stock after video drivers stops working
« Reply #16 on: Sun, 13 July 2014, 13:04:52 »
Heya,

So I have made several 10x rungs on intel afterburner to confirm stable cpu and has started to make a slight tweak to my nGeforce 560 TI graphics card.

I have managed to run 900 core clocks and 2150 memory clocks through 1 single run of Heaven Benchmark with max temps of around 63-64, which is very safe as far as  I understand. I have a tall case with full-speed multiple fans to make a good air flow which I am sure is contributing in some way.

Attempting to run 950 and 2200, everything between 30-40 shuts down Heaven Benchmark and returns video drivers (and my OC) back to stock.

How do I resolve this?

Personally I think I might have a slightly unstable MB/CPU system of some sort, note that I have only overclocked my CPU and not ram.

Specs:

Z77a-g45
3770k i7
Windows 7

Thank you!

I may be completely wrong here as I don't know all that much about overclocking, but could the issue be that the gpu isn't getting enough power to sustain those clocks?

do the cpu and ram seperately.. and use msi afterburner to pump the voltage.. also enable constant voltage, idk if it's supported on 560ti, but it should be...

It's supposed to do this with software OC tools. If the OC is unstable it will 'crash' driver and reset to stock as a failsafe. Are you adding any voltage for your OC? This might help as long as it doesn't hit the thermal barrier or you will end up with it downclocking to 2D speeds or the same resetting. The only alternative really is to alter the GPU firmware clocks and flash the vbios... but you better be sure it's stable clocks or you will have a lot of grief.

Heya,

I wanted to make sure that the problems was not caused by lack of power, so the answer is that I have not changed the power/volt sliders in afterburner, and I´ve not figured how to enable them yet. Sounds like that is a main suspect.

@tp4tissue

Now sure what you mean with cpu and ram seperately, I assume you mean stability tests? I don´t really have any intentions of overclocking my ram as I believe I don´t have any benefits from doing it unless you tell me otherwise. I have plenty of ram memory unused daily.

I don't use afterburner, but I think there is some setting called enable voltage monitoring and overvoltage control or something like that on one of the setting menu. On most GPU you will need to bump up the voltage to reach the max OC. It's often a good idea to doublecheck any fan curves as well before you apply to make sure fans are running higher to ensure good cooling to avoid thermal throttling.

I was thinking it was something like that on the stock firmware. I flashed my vbios when I had my 560ti to resolve that. Sure it was loud on 100% but better loud than shutting down.

sry i meant  overclock  GPU and GPU-Ram  seperately..

in afterburner settings,, use the enable voltage control + enable voltage monitoring

on the bottom there's also, -extend official overclocking limits..

Heya, thanks for replies.

It appears that extend overclocking is only for AMD; but I don´t think I will go that far. My PC spending usually don´t require the most intensive graphics, and If so, I will get a new GFX card.

I should overclock core and memory clock seperarely per your suggestion, so does that mean I should find my MAX core clock first? (Like to the prefered thermal output to maybe 70-75 degrees) and then do memory clock?

Like I am not sure which performance slider costs the most in thermal output / instability or if only the core voltage will increase that. Since I believe it´s only power regulations that increases temperature, it should be no problem to seperately overlock memory and then core.

Am I correct?

EDIT:

In bios I found that my 4 cores has different ratios, probably assosiated with hyperthreading but it also gives different temperature outputs on testing. Shouldn´t all 4 cores have the same ratio?

Also, is there a way to get 75% GPU fan speed to 100% in bios? As far as I understand it´s not the CPU or system fan controls.

vbios is different from your uefi bios. It's not really accessible before loading some OS or another then using some program ie afterburner. If you want to change vbios values you will have to either find a vbios file that someone else already made with the setting you want on like techpowerup or elsewhere and flash the gpu with nvflash or you can edit it yourself how you wish with nibitor.

Also, you might try evga precision X instead of afterburner. It's what I use and it does more or less the same things, but I feel it is less cumbersome to use. Perhaps precision X will let you do what you want easier?

no, you want to do CORE,  then memory..  because no amount of memory makes up for CORE performance..  that is most crucial .

I didn´t understand the last part, what do you mean that memory doesn´t make up for core performance?

I should first try to get my core to the max that my stability+thermal statistics can do, then adjust memory according to what?

I found this quote:

"Core clock increases will always be more effective than memory clock increases, as it is the GPU that does the brunt of the processing. The memory overclock doesnt really increase its speed in mhz, but actually increases its data transfer rate. Increasing the memory clock will allow the memory to trasnfer data quicker, leading to faster loading times, rendering times ect. However, too high a memory clock and you will start to see artifacts on the screen, sometimes to catastrophic effects. I myself have overlocked the memory too far, (Burnt out a 550Ti when bumping up the memory by +1200mhz! Derp). You may well ahve found the optimal settings for your card, so note them down, but contiue to play around with the clocks. I tend now to increase core more than memory, as memory doesnt do too much to increase performance, but a higher memory clock will increase power consumtion. I have even undercloked my memory before now to keep a more stable power supply to the GPU.

With regards to your PSU, Dont worry. I have the same one, and the thing to remember is that the cooling fan on the bottom diesnt turn on until the PSU reaches a certain temperature. Part of the reason for its 80+GOLD rating is becuase it works more efficient when warm.

Hope this helps!"

I think this means I should mostly rely on core OC and not use as much memory OC, maybe +100 MHZ from stock max as I understand the power consumption is worse compared to Core clock.

It depends how good you want to get at SC2. A lot of GM players will set their graphics to medium or even low, because the the shiny colours etc on high/ultra can be distracting.

As someone else said though, regarding performance sc2 is cpu bound anyway.

I read somewhere though, that PRO players train on machines tweaked exactly to competition machines specifications...

I didn't really understand how they did that.. because How do they know the final match tournament machines will be the same spec as during the lower brackets..

After overclocking my GTX 560 TI from 800 to 950 MHZ and memory from 2000 to 2050, I actually bolstered my FPS by 15%, at least in the beginning of games from 120 to 150 fps, which is around 100 to 120 fps when streaming (Lag is still slightly but almost impossible to notice)

This actually makes me think VGA upgrade could be ideal for more fps.

I do know that SC2 is not as requiring on the VGA, but I am dependant on a few high quality VGA settings: Ultra textures, Medium post-processing, High Quality models, and a few other high-quality graphics settings that are not visible in the options.

Basically the only two settings I have on low that are graphics dependant are shaders, shadows and foliage/terrain.

@Tp4tissue

Not that it matters too much, but what is the consequeneces to other applications if I disable hyper threading? Also, is it normal that my 4 cpu cores have different ratios? 2x38, 1x37, 1x36

With that being said, you have any further comments?

EDIT:

I changed the topic.

Well at the beginning of the game, there's basically no units and no action on the map so the cpu does little work and you will see increase fps. But once you get into a battle overclocked gpu or not with the same cpu you're gonna get the same fps.

how do i shot bios?

the uefi bioses these days usually have a screen shot utility or option to save screenshots to a USB Drive WHILE UR IN BIOS..

but a camera is just as easy, and would save you the trouble of figuring out how to screenshot from bios..

You might not have tested your system as stable enough for your activities.

And also on a slightly offtopic note. How does everyone else test stability? I test and pass 12hrs of each prime95 test but still have instability in some games(specifically Need For Speed, hate and gonna uninstall the game but because of the crashing I can't seem to do so until I know i have a stable system that can run it without crashing). Gonna move up to 24hrs and it seems investing time is the only answer? Anybody have experiences with faster testing? Cause I'm planning to undervolt this hot ancient computer at a relative's house this weekend but I'm not gonna have a lot of time to do so. :/

if the processor i'm testing has avx then I use intel burn test.. overnight, 8-12 hrs, then prime small ftt 12 hours,  then prime custom , load max ram minus 1GB..

So 36 hour test suite..

If I don't have avx on the processor, then I just use prime 95 small ftt-12hrs and then custom max ram 12 hrs.

Not that it matters too much, but what is the consequeneces to other applications if I disable hyper threading? Also, is it normal that my 4 cpu cores have different ratios? 2x38, 1x37, 1x36


No consequences to other applications. You're main program might perform a little less as the cpu its using is being shared with other applications but its gonna be negligible. I believe that's when one or two cores are running cpu runs at 3.8ghz, if 3 3.7ghz, and if 4 3.6ghz. Normal. Some people like to set it all the same but doesn't really matter.


Reread thread and..
Why is it that my tests on 1.15v, since my temperatures are this low, is basically unstable at even just 975 mhz core and stock memory frequency? I see artifacts, a few spikes and stuff right before a crash in heaven benchmark, usually 40-60 second into the test.
Low temperatures does not mean stability. You can be at 50C and still crash if you don't have enough voltage for your frequency. You may just be unlucky and have not so good overclocking card. Lower your core frequency until artifacts dissapear and than see if you can raise memory frequency.

Oh right! Forgot about changing ram amount. And guess I gotta try out intel burn test again. Couldn't get the program to run probably last time.

depends on your cpu.. if it doesn't have avx.. there's no reason to use intel burn.. just use prime..

Has avx. Ran 20 runs very high but still stable.... just gonna uninstall need for speed lol. All my other programs so far runs fine. And also, related to haswell voltages, I know theres a new voltage vring that controls cache and uncore voltages. Previously vring voltage was same as vcore's right? With haswell they made it separate and im getting conflicting answers online as how to set it. Out of curiosity @op whats your vring set as? Actually... just gonna say like the others have post your bios shot.

vring set to 1.225      <1.25 is recommended..

on my g3258 haswell I can get 46x core 42x uncore out of 1.225 vring..

The reason I use 1.225 rather than 1.2, is because these things droop..

after you find stable voltage.. always go a step UP..
