ATI HD 4770 reference @ 1000MHz-stock cooling with 4770 Top bios and Asus stuff

PcCI2iminal · 05-02-2009, 01:33 AM

Decided to flash one of my new ATI HD4770 to the Asus TOP bios so now I can use CCC to 1000Mhz GPU , 1200MHz GDDR5 and Asus Smart doctor's voltage adjustment works fine ^^ and now 1000MHz @ 1.21v and GGDR5 @ 4580MHz is possible just with fan @ 100% with is just crazy for that cheap card

well its not safe to use cz at these speed have started to show random green lines and artifacts on the display while using Vantage.

STEvil · 05-02-2009, 02:30 AM

Would be fun to LN2 one of these

Spectrobozo · 05-02-2009, 06:25 AM

wow, that's really good!

~~ILikeCosmosS~~ · 05-02-2009, 06:29 AM

its 40nm what do you expect?

i wonder if this could beat the 4890 or better at those clocks

purecain · 05-02-2009, 06:58 AM

i wonder why the asus voltage tweak software wouldnt run on flashed 4890's.... any tips m8...

Blue Storm · 05-02-2009, 07:32 AM

with hardware volt-mod I think it can go 1,2GHz and over

I will have some HD4770's for testing, so I wonder what they get

Lightman · 05-02-2009, 08:03 AM

OK! Second GPU which can do 1GHz on stock AIR (first being RV790)

!

Really impressive to see such clocks from a low/mid end card

Will it go any further?

Don_Dan · 05-02-2009, 08:44 AM

Thanks for showing your results!

These results make me think about switching over to ATI after a long time of using NVidia cards...

Will you test the card on a C2D system or i7?

Dua|ist · 05-02-2009, 08:50 AM

Great news, thanks! I always thought it's gonna be a monster chip.

Could you please give us an estimate for everyday use max clocks (not 100% cooler and with no artifacts)?
And what is the temp like under Vantage load?

Thanks in advance!

crustytheclown · 05-02-2009, 06:04 PM

Nice these cores scale like the 4890's ones!!!Good work

Meaker · 05-03-2009, 03:30 AM

Please could you link the bios? Mine reach around 900/1075 at stock volts with AA S1s

That is not a big feat, i can do 960/1100 with my 4890 all day long and that is with the older process at stock vcore. I was expecting something in the 1200mhz for the core

. Hope the new process gets more refined for the high end cards in the 58x0 generation.

Astennu · 05-05-2009, 10:38 PM

Nice scores PcCI2iminal !!!

But are these retail cards ? Or handpicked ones ? I realy like those clocks. I'm thinking of buying one. But i dont know wich one yet. Should this bios trick also work for the sapphire cards ?

What do you expect ? the 55nm tech is as good as it will get. And 40 still brandnew and not optimised. + the HD4770 is made for low power consumption. And it should not get faster becuase then it will hurt HD4850 and HD4870 sales. But it can be clocked at 900 with no problem.

Also dont forget that the HD4890 stock is running higher voltages then a HD4870. (1.31v vs 1.25V). I think we will see 1100+ air with those HD4770 cards. And more in the future when the 40nm process gets more mature.

It works for the Sapphire cards. I bought two of them and flashing was no problems at all. But the clocks were crap, I got 870MHz on the core and only 860MHz on memory for the best of the two on stock volts. When added volts up to 1.2 volts I got 930MHz on the core and memory the same

ty clock. Max temp were 78c in my fairly warm room. Not happy with these cards, especially mems...they should do at least 1000MHz.

Drivers are crap ofcourse, based on Catalyst 9.2. But it's just to far from acceptable for me to give faith in correction with better drivers.

Astennu · 05-06-2009, 01:42 AM

Strange that you mem OC is so low :| i realy hope my card will do well. Else i will keep the HD4850

and put this one in a other PC.

In that case i guess PcCI2iminal has some handpicked samples.

I will also try a other cooler on it. And i will try to install a 4p fan connector so i can fan control it trough the bios. But i will first check if the ASUS TOP bios has support for fan control.

Owh well i will know whats what soon enough

Getting the card today. First run will be tonight. I will also try to use the 9.4 driver. Forcing it to be a HD4850 or something. Sometimes that works aswell.

Clint · 05-06-2009, 07:10 AM

Yes, considering it's AMD branded cards with the skimpy cooler and lite PWM I believe they can be handpicked. Gonna be interesting to see what your card can do.

Astennu · 05-06-2009, 08:43 AM

UHmm 850-1100 so far. Cant use the Asus tool because my max clocks in that tool are 850-900 :S And if i use it to set the clocks and then use CCC its setting my clocks back to stock.

How did you guy's go over those clocks with smartdoctor ? if i close it i think it sets the voltage back to normal again. I will try to measure it.

Edit: Never mind. Its holding its voltages when closed. You need to set your voltage with smart doctor. Then close it. Open CCC and set your clocks. I noticed that if i set max 1.3. I get 1.324 idle and a whooping 1.4 at load. And then it crashed. With 1.1 (1.17v load) its running just fine. So ill be testing that. i also got a Zalman VF1000 over here that not being used. I will first max out at stock cooler and then Try the VF1000 to see if it helps.

ChinStrap · 05-06-2009, 10:25 AM

whats 1GHz core look like 06'?

Astennu · 05-06-2009, 10:32 AM

I tested my sapphire and it maxes out at 860-1115 fur mark stable error free. I could get 900 core with 1.15v. Everything over 1.15 would make it worse. RBE is not supporting the HD4770 voltage tweaks yet so i'm sticking to 860-1115 for now. If the suppor comes i could upp it to 900-1125/1150.

100% fan speed did not do much over stock. It boosted it only 10-15 MHz max.

Furmark 1680x1050 750-850:
Score: 3236
FPS Min: 45
FPS Max: 80
FPS Avg: 54
Time: 60000 ms

To: Furmark 1680x1050 860-1115:
Score: 4185
FPS Min: 60
FPS Max: 100
FPS Avg: 70
Time: 60000 ms

at almost stock mem was 50 MHz higher then stock. Cant go lower anymore with this top BIOS :P But a not to bad score for a 89 euro card

Clint · 05-06-2009, 10:57 AM

Astennu, intersting clocks. Especially the mems. It really bugs me that both my cards not even managed 900MHz on the memory. Did you use the drivers that came with the card, or did you force the Catalyst 9.4 like you said?

EDIT: Looks like the XFX card with a decent cooler is coming shortly here in Sweden:
http://www.dustinhome.se/pd_5010313738.aspx

5 euros more than the Sapphire, so they are going back.
If that shop has it up then the XFX is not too far away.

ahmad · 05-06-2009, 10:59 AM

Thats not surprising, what is surprising is you have the "cheaper" version.

If you had the more expensive one, it may go much higher.

Huh, what do you mean? All those with the skimpy cooler and lite PWM are supposed to be the same. And the other cards aint out yet.

Please explain.

Yep i forced 9.4

I installed it as a HD4800 series. Works like a charm

Did you also flash the TOP bios ?

Not totaly true see the stopic starter. He is getting 1000 MHz out of a light version with the cut down power regulators. (but i guess they are handpicked). But still you dont need the extra power regulators you need a good chip. But i think the OC editions will have those better binned chips and will clock higher. And Maybe allow a higher v-mod voltage.

GeorgeStorm · 05-06-2009, 01:15 PM

Wow, great clocks
Looks like this really is a card to look out for.
