More powerful AMD overclocking program.

[Bubbleawsome]

I have an HD 7770 and I was looking into overclocking it farther than it is right now. (1100/1564 vs 1000/1125 stock.) The HIS (iTurbo) program comes with voltage support, but does nothing, neither does afterburner.

I am looking for something else that might have more access before I give up and say it's locked. I don't believe it is because reviews for it have overvolted it to 1.25, while 1.2 is stock.
It's plenty cool, so it'll be fine, but nothing lets me do this.


Thanks in advance!

I am guessing you bought low end card because of budget. I would advise against risking card damage from adding voltage and ending up with no card at all.

Some lower end cards don't have the proper chips to do software voltage control. Try searching google for your specific model and see if anyone has done it before.

Will do.

had no money at the time, now have enough for a 7950, I was going to get a better HDD and SSD if this card gets better from overclocking, but right now it doesn't cut it.

adding a little voltage for wee bit better oc is not going to make any playable difference in game where a 7770 is not meeting your needs at the settings you want though. I would simply just lower some settings if you cant afford a better card.

Turns out they used to, but the newer ones don't

Everything deserves a bit of overclocking. Worth a shot to load up Trixx just to double check. If you do manage to find a utility that can manipulate voltage watch your temps. Looks like 7770's max out around 1.2 to 1.25v.

Those cards have locked voltages as far as I know. Just about every 7770 and lower does. And even at that, they do not OC well at all. They just arent designed for that in mind.

HIS cards in general are voltage locked.

Depends on the card. Mine in sig is unlocked. Afterburner allows up to 1.3v's

no everything does not. Plus he already has the card overclock and is just looking to squeeze a little more out by bumping the voltage. again he's going to end up with miniscule results at this point over the overclock he already has.

Yes everything does. There are many others here who will get the most from their equipment, even if it is, in your OPINION, miniscule. If the OP took the time to post here and specifically ask to overvolt that should tell you something.

Can you post a photograph of the circuit board, there may be a guide to a voltage modification you can perform, e.g., using a pencil to increase the voltage.

Is your circuit board blue in color?

it's beyond ignorant to think that everything "needs" to be overclocked. And just because the OP ask the question does not mean that he should overvolt his card.so yes it may be my opinion but overvolting a low card like that for just a few more megahertz is stupid for what will result in zero playability increase.

 

[monkeydelmagico]

Yes, it is beyond ignorant to assume your view is the only correct one and ignore the origional poster's request.

The risk has been explained as well as the expected potential. That being said a voltage increase to around 1.3v has gotten folks to around 1300mhz on the core. Yes it is stupid of you to assume a couple hundred mhz is not going to result in a playability increase.

lol at you thinking he's going to get a couple hundred more megahertz over his current overclock from bumping the voltage slightly. And I doubt he stand a chance of even getting to 1.3 anyway which would certainly not be good for long term use. But yeah let's encourage him to risk damaging his card which sounds like a real good idea considering he was on a budget in the first place.

I believe so, currently at school.

I believe it could handle most temps. Never goes above 60c with current oc and locked 25% fan.

Overvolting is my last choice before a new card. The old type card got a 1100 core in the review while with a vcore of 1.25 it got 1250. I can play for about 5 minutes on 1200 and it made some games playable. It delimts the memory and with 100GB/s possible I'm sure that would help. My past max was benching 1300/1600. Play at 1100/1241.

Lol at you for thinking it can't happen, an do so reliably. A quick google shows other people's results. Looks like there IS some headroom on 7770's if you know how to go about it. OP has already posted he has the money to get a 7950 so there goes your budget argument...... but if you want to breaking out the shovel and dig a little further be my guest.

OC'ing might get him a few more frames at his current lower settings, but if he's trying to up his image quality it's still going to tank, OC'ing isn't really going to matter when you look at it that way. I definitely wouldn't push 1.3v in the off chance it dies, when the card still has some value to resale. Once you get your 7950 sell that card and recoup some of the costs to put towards a SSD.

you are a fool if you think a small overvolt is going to him another 200mhz on top of his current overclock.

 

[KingFatty]

Meaning, it's foolish to think he can accomplish the same frequency that other people have already accomplished and posted about? I dunno, I think it's commendable to encourage other people to try to accomplish more, especially when it's been demonstrated to work?

show me one person with a 7770 who got an ADDITIONAL 200mhz from using 1.25 over what they where able to oc to with using stock voltage.

I am seeing 1150-1175 being a decent typical oc without voltage increase you and him are claiming 1350-1375 with 1.25. please show me that as I will be impressed.

 

[Face2Face]

Using this article as reference, even with a nice OC (1235MHz) I am not really seeing large gains like with Tahiti. Might not even be worth it....?

Thats my card! (Older version though, maybe BIOS flash would do it? :/)

The game I struggle with the most is mc with shaders. I play fairly often and I used to get a playable 30, now it gets 15. I know that because of the shader programs coding it needs more memory bandwidth (and I have that) and even the increase from my previous oc of 1075 to my 1100 now I got from 12 to 15 fps. So if a 1250/1300 is possible I fully see 30fps with a bit of my own shader code.

I think 30fps is very optimistic if your getting 15 at 1100. Your going to have to change other settings to get playable FPS. Using the article
Face2Face found as a good reference point even if you get to 1300 you will still probably be around 20fps without changing somethin else.

This guy did some work on his and mananged a 1325.
