3D Mark Vantage Run with i7 920 @ 4ghz and CF 5870 (900/1300)

[Mikrouwel]

Hey Guys,

I got my 2nd 5870 the other day and finally got around to some benching

This is what I get with my 2 x 5870 at (900/1300)

I am happy but I am going to try and go further now

Let me know what you think

From what I'm seeing on that screenie, both GPU clocks don't match.

They should both be at the same speed for optimal performance.

Yes the reason they are not the same is because I have to set the on with Smart Doctor and one with mis afterburner and smart doctor cant be adjusted with arrow keys

Will try and get them the same and post up

MSI afterburner I have used, there should be an option to sync both cards.

Anyway, have fun

HI There,

The prob is that MSI afterburner cant change voltage on the asus card so it gets confused and keeps on switching them both back to stock

Will fiddle around a bit more and let you know

Thanks

Did it get you many boints?

 

[Mikrouwel]

No, im new to it but I think I got ranked 100 odd out of 150 or something :/

 

[Stromatolites]

Well the Asus card is clocked higher so shouldn't you be able to just up the core on the reference card to match the Asus?

 

[Mikrouwel]

No I cant because the ref one is locked at 900/1300

How do I change that?

Thanks

You would have to flash the bios to a unlocked bios such as an asus or msi. I have mine flashed to the MSI bios, and have managed 1100MHz core 1300MHz mem.

I could try and find a guide for you if you feel up to flashing the bios?

 

[marsey99]

i would run them just on the asus card alone to see if that gets you higher up the single card charts

 

[Mikrouwel]

I am right in saying that it would void warranty right?

If not then can you find me guide plz

Thanks

have you tried unlocking the voltages in the afterburner config file or in the settings?

 

[Mikrouwel]

No, how do I do that?

[thestepster]

have you tried to unlock it in settings? if not try this, setting > general tab > safety properties > check unlock voltage control and unlock voltage monitoring

to unlock voltage in the cfg go to where you installed afterburner, right click the cfg and open with notepad

scroll to the bottom and find the voltage conrols and make sure the value is 0 and your done

 

[Mikrouwel]

Thanks for reply,

I tried in settings and not workie

SO I went into .cfg file and changed unofficial overclocking to 1 and it unlocked it but then when ever i try and set the clock (even 1mhz) in afterburner i get freeze and then bsod

Any thoughts?

[thestepster]

have you got the newest version of afterburner?

 

[Mikrouwel]

Downloading now

Thanks

 

[Mikrouwel]

While they downloading I did a run with them both at 900/1300:

Thanks for the help so far guys

The weird thing is that I see people with 2 x 5870 @1000Mhz core and getting 33000? :/

Why am I so special?

 

[marsey99]

Better drivers?
