If it uses the volterra controller, you could use this method. I'm eager to see some sick 40nm OC's :p

According to the Asus info, stock is 0.95 while 1.2 is maximum before you get to a hardmod.
Not volterra, so it should require some hand magick ;)

It's not Volterra, but the chip has I2C bus and voltage can be adjusted by software (ASUS Smart Doctor). I guess Rivatuner would work, too, but I can't scan SMBus due to unsupported driver.
There are two versions of reference board, one has less capacitors and glaciator-like cooler, and the other has all caps and a rear exhaust cooler.
Stock voltage is 1.05 V (3D) and 0.92 V (idle). Max selectable in SmartDoctor is 1.30 V, which gives ~1,33 V real under load (measured on reference board, the lite PWM variant).
Controller is ST Micro L6788A (http://eu.st.com/stonline/products/literature/ds/15341/l6788a.pdf).

I didn't test the card, it was my friend Mieszko (bedlamite here on XS). He got 900 MHz when clocking the core alone, 1150 MHz with memory alone, 850/1110 with both core and memory on the full PWM version, 850/1040 on the lite PWM version.

The asus TOP looks like a reference card.. and the voltage regulator can be adjusted by software... but since it doesnt look like the TOP will be launched, it might be hard/impossible to get the bios (and they might not have 4770 support in smart doctor)

Would the bioses even need to be different between the two cards? I would like to add the full power regulation circuitry. I have spare caps and I'm sure I could find proper mosfets. I know most people would just say that I'm dumb and to buy the other version of the card, but it isn't refundable and I'm confident in my soldering ability. The card gets here tomorrow evening and I plan on volt modding it before I go to bed. I've figured out 2 volt mods on my own before, a 6200TC I did a week ago, and my non-reference HD4850 I did last night. :D

On my HD4850 I did a couple days ago I get 1200Mhz stable in Farcry2 and Furmark without artifacting at 2.137v and that is without ram heatsinks. However, you should see how much the memory clock affects the core temperature and at those speeds it limits the core overclock. GDDR5 should run considerably cooler but I would still get some heatsinks on it.

Cool. I'll probably try it out but I'm slightly more nervous about the bios flash than soldering.

So I've been testing it with furmark for the past hour and out of the box this card appears to be stable at 859Mhz core and 1131Mhz memory. At 1140Mhz memory there was one visible artifact after 5 minutes but nothing else after that for another 10 minutes. The card peaked at 64C core inside the mATX case. It is probably 70F with the window open right now.

Ok, I flashed to the ASUS bios and now in smartdoctor, I see that I can't up the memory voltage? It didn't cross my mind that the memory voltage controller chip wasn't quite of the same caliber as that for the core voltage. I will definitely have to get into there with a soldering iron.

Waiting for info on clocks with max voltage.:up:
I flashed to the TOP BIOS as well. With SmartDoctor installed, max voltage is 1.3V.
No idea where to measure the voltages with a DMM.
I can bench @ around 920mhz/1075mhz with 1.3V and max fan speed. There are visible flickers at this clock but no crashes.

What were you able to get stock? I thought I was stable at 954Mhz and 1.072 volts in smartdoctor, but I got a BSOD out of nowhere. I was creeping up the clocks very slowly until I saw artifacts, then I would up the voltage a smidge and go back to creeping up the clocks.
The stock cooling is pretty crappy though. Dropping the memory from 1100Mhz to 1000Mhz dropped the core temps by 4 degrees C. 100% fan of course. Right now I'm trying to figure out how to get the clips off the Accelero S1 attaching the fins to my HD4850. At the same time I'll wire up a molex connector to read the actual voltages.
Just in case anyone cares, I read 2.020 kOhms between FB and ground on the GPU power controller. Here is the data sheet: http://www.st.com/stonline/products/literature/ds/15341.pdf

At stock voltage, the max I could bench was around 865mhz core, but that was not stable at all, sometimes I pass, sometimes it just crashes. Max 100% stable at stock voltage seems to be around 840~850 for me.
Quailane
05-02-2009, 12:33 PM
Ok, no matter what I do I can't get it 100% stable over 900Mhz core. Even with the accelero S1 on there and didn't change anything. I'm pretty sure this is a power management issue. Even at stock clocks, running furmark the voltage doesn't stay steady. For example, at 1.05 volts in SmartDoctor, I got a first reading of 1.01 volts, and then later a reading of 1.03 volts. At stock voltage and clock settings of 800Mhz and .95 volts, I read between .90 and .91 no matter when I did the measurement. Also, setting the voltage to .90 volts in SmartDoctor, Furmark immediately crashes. Unfortunately I don't have any polymer capacitors with the same or similar capacitance and voltage ratings as the ones on the card. I will try to find some though. Also I'm not very hip on mosfets. I think I can just put some on with same or better current and voltage rating; is this correct?
The memory voltage is very consistent at between 1.49-1.50 volts under load and idle.
I also added to that picture:

Lol. You are right. I was using a cheap Sperry multimeter I bought a month ago. I whip out my nice 6 year old radioshack multimeter and it gives much different readings. .968 volts idle compared to .87 volts idle on the Sperry. I tested my psu voltage rails with the Sperry and they were way low so I adjusted them up. My radioshack tells me the 12v is 13.41. Haha.

AMD. The cards were all made in the same factory and shipped to the different companies who just put their own sticker on the fan and threw it in a box. Next weekend I should have my card with the extra mosfets and loaded up with Nichicon 470uF LF's for the 16v and 1500uF LE's for the 2.5v sections. I'm also working on finding some really good copper cpu heatsinks to cut up for the memory and mosfets.
Oh, I just want to add one more thing. I don't think a volt mod can push more than 1.35 volts through the card because according the spec sheet the controller chip is limited to 1.35 volts.

Wrong.
1.35V is just the limit for setting the voltage via the vid pins.
According to your theory, not a single Socket775 board could provide more than 1.6V Vcore. And you know why? It's because 1.6V is the vid limit. ;)
However, you can use much more than that, by not using the vid pins to set the voltage, but the feedback loop. In fact the datasheet says that OVP is 140% of the voltage set by VID. So you could run 1.35V * 1.4 =1.89V VGPU. ;)

Asus Smartdoctor allows you to set it to 1.3V. However, when I took my DMM to the card, I measured in excess of 1.4V, on both my cards.

You can do it with atiflash. You need a bootable USB drive (this excellent guide (http://www.techpowerup.com/articles//overclocking/vidcard/34/5) at TPU tells you how to do it) and atiflash (downloadable from TPU as well).
Boot form your USB stick, type "atiflash -s 0 name.bin 20000" where -s means to save a bios dump, 0 means to save from first graphic adapter, name.bin is the name of your saved dump, and 20000 is perhaps the most important - it's hexadecimal for 131072 bytes or 128 kB, it's the size of bios data to read. Saving bios with GPU-Z will only save first 64kB, and flashing your card with 64 kB bios will brick it.

Hmm recently bought two 4770's myself. Tried flashing to see how much I'd gain. Sadly not much.
The flash process was straight forward (for those that don't or can't make a USB bootable drive I recommend Ultimate Boot CD for windows, google it).
After flashing the latest version of smart doctor would start (5.38), and I could adjust the gpu vcore slider upto 1.3volts. Selecting anything over 1.25v would cause a nice crosshatch pattern to appear on my screen and hard lock my PC. So at least I knew my limit :)
Before the flash I could get 875mhz core, and ran at 860mhz for 24/7 stability.
After the flash I could at least complete 3dtoss runs at 900mhz core but it wasn't stable I've had to drop back to 870mhz.
I think taking these two cards out, removing the heatsinks, and re-applying some thermal goo may be the go if I want better results.

vGPU:
My dmm showed 2.01kohms (~0.9V) default resistance for GPU.
After adding a 50kohms VR (@max) the resistance went down to ~1.6kohms which was a little too much for my taste.
So i started over using a 100kohms VR which worked out just perfect (1.94kohms).
vMEM:
Default vMEM was 1.65V.
After soldering in a 50kohm VR (@max) it went up to 1.82V which is ok with me.
If you want to play it safe use a 100kohm VR for vMEM too. ;)

The card overvolts 0.5v on the core compared to what is set in Smartdoctor. As for RAMs they get feeded with 1.65v.
If I cool them properly, how much could I feed them for 24/7 usage?
Do GDDR5/Quimonda scale good on voltage increasing?
I don't know how it is with Quimonda GDDR5, but Quimonda memory on 8600GTS wasnn't good for OC. Even 2.3V(vmod) I couldn't pass 1200Mhz, 1000mhz(deafult).

After soldering in a 50kohm VR (@max) it went up to 1.82V which is ok with me.
If you want to play it safe use a 100kohm VR for vMEM too. ;)
Here you go:

I have modded mine cards but they dont need much voltage jult 1.17vgpu to do 1050mhz on air and 1.7vmem to do 1250mhz
I'll found the best one ( my friend ) 4770 @ 1025/1200 vgpu 1.111
GPU Score > 10.000

just 1 word : FANTASTIC :up::up::up:
I have HD 4770 version where are missing few MOSFET and capatitators. Are there any diference in OC performance?
And what, if I buy exsact mosfet and capatitators, will be something differnet?

With the right voltage and the right settings in driver and clocks in 2d/3d in bios they kick ass...

Awesome score man! What are those driver settings you are using? I've been playing with my 4770 on 3dmark06, unlike you I can't get close to the i7's on total score. My best so far is 18453 (http://www.hwbot.org/result.do?resultId=882062) at 1025/1225.

Use all set to performence and ccc AI disable and then you have to try different voltage for the gpu it helps and try running vantage

I can't get anywhere near your vantage gpu score...
I've tried all I can think of. I set all the gpu bios settings to 1g/1.2g in rbe and run my phem II x4 at 3.8g. Regardless of CCC settings I always seem to come out around 9300 on my gpu score. This seems to be approximately the same score everyone else is getting on hwbot. Have you tried running 3dmark06?
I finaly make vmod and I wanna ask you what are max V for vgpu an vmem?
Up to what point I can raise the voltage safely? Now I got 1000 mhz on gpu (watercolling) with 1.160 vcore, but my card be more, I think...
You can go for vgpu = 1.35V more you can't becouse the card have over-current protection.
1Ghz on 1.16V? Does it work in 3Dmark 06 and other test programs?

If u use asus smartdoctor to go for 1.3v then u can use hardmod to go up to 1.65v
my 5 cards can do 1000mhz at 1.15v 3d01-3d03-3d05-3d06-vantage stable
How can you get to 1.65V? I have saphire 4770 and voltmod for gpu and mem(hardmod) but if i set vgpu over 1.35V the card turn off.

I test my card in fumark stability test and 2 hours gaming in Crysis. All right. :)
gddr5 must run on 1Ghz at stock voltages too, becouse as I know this ram is made to run on 1ghz.

Look at my post if you use asus smartdoctor and set the voltage with software to 1.3v then you use hardmod to go higher..
you have to have the card flashed with asus topbios
Aha, thanks, will try to flash and will see.

Hi guys, I would like to know if someone managed to overclock with rivatuner without disabling SmartDoctor voltage regulation? When I use RT, the voltage goes back to stock value (1v) and It's quite disappointing. The card can run 3d mark 06 @ 970mhz core with defaut voltage, which seems to be a good result and is, of course, stable @1Ghz with 1.1v (CCC will work with SmartDoctor but won't go over 1GHZ :(). I don't want do make hard mod for now if soft solution exists (it seems like Riska managed to make them work together)

Just minimize smartdoctor to tray and it should work but it works also if you close asus smartdoctor but you have to press ok to set voltage and mhz
Clemmaster
09-09-2009, 08:17 AM
Thx, in fact this was working, but the card seems to have limit around 1ghz, because it won't do more than 1060 @ 1.3v when it is able to run 970mhz at only 1v :(
Did you do anything special to run that high with yours? (1225 is a great result :D). Maybe have you got the press release version?

THANX, anyway that not mine ! :p:...really my friend !

No got the retail version but modded it my self to the press release version + some more mods and i am using standart watersetup to cool the card and it never goes over 50c with 1.61v
I recive 2nd card 4770 but this one have BLUE PCB and vgpu controler isn't the same as on card with red pcb. Any sugestion about hard volt mod?

pal, uP6201BQ ?
Measure resistance between pin 13 and 4(or any GND).
Yes, it isuP6201BQ and pin FB to GND is 3.30Kohm.
EDIT: Can I flash this card with Asus TOP bios and then try with SmartDoctor. Will it work fine?
no, it is the same chip on the PCS hd4770: no compatibility with smartdoctor:
http://www.techpowerup.com/reviews/Powercolor/HD_4770_PCS/4.html
Thanks for link but my gddr5 can't go over 861Mhz at stock voltages.
Then mybe this chip do not have OCP protection like other chip.
This HD4770 from Shappire with BLUE PCB has very hard problem with mem overclocking. It looks like it have bigger problem than PCS hd 4770 becouse on that test they oc memory to 1050mhz and they found some issues but on this card this issues doesn't help.
Is there any chanse to get new bios for this card?
anyone any idea?
Hard volt mod for memory doesn't help.

maybe a closed pic from back and front side will help to made people found what the diff with a red ones,
sorry my bad I dont see you have upload some pic before
Yes, but those pictures are bad. Differnets beetwen those two cards are that blue pcb card have diferent vgpu controler, I think is the same as on 4850. But I think this is not a problem becouse I can OC gpu to 950MHZ on stock voltages.
vmem controler is the same as on red card and also volt mod is the giving more voltage to memory.
I think it is the same crap as this card
http://www.techpowerup.com/reviews/P...770_PCS/4.html
There, in Overclock section, they found some problems with overclocking, but on this card what they wrote, doesn't help. Also my friend have the same card, Sapp, HD 4770 blue PCB(Artic Cooling) and he have the same problem with memory overclocking.
Maybe we need just a new better bios for this card.

you are lucky actually My sapphire red card 4770 only can reach 860 on GPU and 1050 on mem I still looking for multiturn VR to bring up the voltage, I am not so keen in flashing Bios.
Here you have volt mods.

One pin from trimmer to yellow point and other on GND (-) whereever you want. I normaly use GND from PCI-E power conector.

First check, if you have the same VGPU controler and then do something. I use 100kOhm trimers(64W).
With cgpu mod you will can raise voltage till 1.35V , if you go over the card will turn off and you will need to restart. Why? Becouse vgpu controler have Over curent protection.
If, you want go over 1.35v on gpu you will first need flash your card with Asus TOP bios, than set max voltage by software and then raise voltage by trimer, I think.

Finally today I can do something with my 4770 first I like to try a soft mod use asus smart doctor and I got 954 on GPU and 1033 on RAM (it can go higher but I need 24/7 stable for folding)and I found 2 problem :
1. smart doctor only allow me to go to 850 so I must use riva tuner and thing get complicated when I boot up the computer the riva tuner setting is lost and back to asus setting, any body has a hint to solve this ?
2. I can't find any RAM voltag adjustment asus, must I use hard mod for RAM ?
Did you flash the card with ASUS top BIOS? When you flash with ASUS TOP bios then you can OC in CCC to 1Ghz. For RAM I think there are no voltage adjustment, only for vgpu.

hello
i have 4770 from sapphire and club3d. i flashed the cards with asus bios, but i am still unable to change the voltages all the way up to 1.2V
only thing that works is ati tray tools and it has 0.9-1.05 range. smartdoctor, gpu tune, afterburner have no impact in voltage change.
does someone know a solution to this?
thanks
