Oc 7770?

[Pelop17]

Hello,

i want to oc my asus 7770 cause i thought if i oc it it will give me more khsh?

Now i have 168-170 khash. I want to oc it at least to 200khs or more if is a safe oc?

 

I dont know how to do it current gpu clock: 1020

                                                  memory clock : 4600

 

Should i oc both of them to get more khs??

[Lays]

as long as you don't add a crapton of voltage it should be fine.

Yes i know that. but the problem is that how do i oc it?

should i change only the gpu clock or the memory or both?

[Toxic Tom]

Try GPU 1100MHz and Memory 5000MHz and see what happens

should i oc it first and then start cgminer?

[Toxic Tom]

Yeah

[Pelop17]

Yeah

i oc it and i get 186-190khs. It ok ? ot should  i push it more?

If it's completely stable try 1150MHz on the core and leave the RAM where it is

[Prokart2000]

you could push it further if you want but im not sure how far it will go as the card may not like ocing

It looks like it does so far!

I find vram on my cards being Oc'd doesnt give me any benefit in cudaminer, I'm unsure how AMD cards work with it.

 

 

You can OC whilst having cgminer open, it shouldn't hurt anything, and it will let you test how stable the overclocks are.

Its stays the some

 

I want to oc , so when my other card comes apparently 750ti that can get 300khs i will oc it to 350 so total i will have about 540-550khs which is good?

By "Its stays the some" do you mean "At 1150MHz on the core and 5000MHz on the memory there is no increase in hashrate"? That is normal. You will reach a point where overclocking the card further will reduce the hashrate.

ok thanks.

When my next card come i will be fine!

But i have also a 6670 siting around that gets 100khs without oc if i oc it will it get more or should i sell it and store the money to buy a 290 or 280x?

Depends how much you can sell it for

[Pelop17]

Depends how much you can sell it for

i dont know maybe 60-70 GBP

 

I have a question also the 270x is better than the 750ti in khs and in gming?

The 270x is better but it is much less efficient and more expensive

[Pelop17]

The 270x is better but it is much less efficient and more expensive

what do you mean less efficent ?

[Pelop17]

The 270x is better but it is much less efficient and more expensive

also can i asked you something? What card do you have in your system?

[Toxic Tom]

what do you mean less efficent ?

 

I mean it uses more watts per kilohash

I have a 270x

[RatedBlam]

With mining I'vr found that it's a delicate balance.

I had minimally overclocked settings that gave me about 195 Kh/s on a gigabyte 7770.

But then I messed up the over clock, lost the settings and I haven't been able to return

I have a 270x

ok thanks.

I recommend you buying a msi twin frozr 750ti

[Toxic Tom]

ok thanks.
