New 560 448core. Overclocking and some afterburner/heaven questions.

[Threepwood]

Hey

So a shiney MSI 560ti 448 edition landed on my doorstep today and Ive been merrily overclocking it this evening.

1st wow, it keeps uber cool and second, yeah great overclocker. So far my fastest Heaven run (as per the heaven thread settings) has been 1255 with 1000core, 2000shader, 1950memory @ 1.062/1.125v. But this came with just a couple of artifacts.

After dropping this down to 975/1950 with the same memory and voltage it brings it to a score of 1239 with zero artifacts, run after run after run.


Both these runs show GPU temps staying below 65oC. Edit: The card idles at 32oC.


I would love to get it running at 1000/2000 BUT the afterburner slider will not go any more to the right . As a side note the new + - voltage on the afterburner beta threw me for a while until the brain fart passed and I told the program to show the card voltage in the graph section.

I want to get the voltage to 1.15 as I have a feeling this will give me the 1000/2000 with zero aftifacts, but is there any way of making afterburner do this?


Another question is I cant seem to get afterburner to unlink the core/shader like I am used to in the past, is there any way to force this? Is it just the beta? or?

Okay, lastly my heaven bechmark pic is showing "Intel(R) HD Graphics Family 8.15.10.2509 1814Mb" which is the 2500k's IGP is there any way to help to show the GPU instead?

Cheers , oh, and any tips for getting the score higher would be greatly appreciated also!

(not been on this comp since new year and its still showing smiley faces with Xmas hats, lol, DOUBLE EDIT: Oh pants of poo, they have now gone)

Dont be shy! any input would be fab.

 

[Threepwood]

Anyone?

You can't unlink shader/core clocks with the Fermi based nVidia cards it literally works as core domain and for the shader domain aka hot clock it just runs at double clocked of the core domain.

Don't think theres a way to stop Heaven showing the wrong card other than removing it entirely from the system - disabling in device manager might work.

 

[Threepwood]

Thank you Rroff, and will try that

Now to find out how to give it a little more voltage, it might be bios limited from what I'm reading online and realised that the person reporting higher possible volts probably had a card from a different manufacturer. Off to see if there are any alternative bios over at msi.

can raise the max allowable voltage with a bios mod using nibitor and then nvflash. set voltage limit higher to something like 1.2v if you want. but remember heaven is not as stressful a test as OCCT will be.

if you really want to get solid oc results, test for a few hours using occt, with the exe renamed to something different like tester.exe, this will help bypass any driver level overcurrent protection so you can get proper results.

also do what i did, when bios modding the card you can drop the 2d clock voltage, on my 560 ti i got the card set to 0.825v for 2d operation, made a big difference to idle temps and power consumption.

do note that the msi twin frozr card i have has a nackered fan, msi cheaps out and uses sleave bearing fans so they wont last long at all.

I'm guessing this will void my warrenty as they will be able to see the altered bios? Presuming that if it broke I wouldn't be able to change it back?

Which, if so is a shame, the 2d idea makes so much sense.


Sad to hear about the sleve bearings, I guess i'll have to wait and see, did you RMA?
