tested and aproved, for results see hwbot 5750 categorie ;)
Thanks guys :D
What IC's? Hard to read from pics...
sorry :) it is a uP6201BQ
What about Vmemmod any one found that i am getting four HD5770 soon
The 5770 reference has no IC2 interface ? Aka soft vmod, if you flash it to the asus bios you'll can use the Asus software for change the vcore.
Best regards
Wy is it that it is only asus there can make software with voltage change for the HD4770 and HD5770?
5770 has Volterra VT243WF memory VRMs (those north of GPU VRMs), and those chips don't need any external controllers so no need to try to find one.
Shamino posted a possible mod for VT242WF over here - and it should work on VT243WF too. If it works on VT242WF, that is.
Thanks alot for that info
The vgpu mod works fine it is the same as on the HD4770
I found this a couple of days ago...
Do u think it would work???

As what ?
Is it memmod for the 5750?
Where is it located?
Edit found it...
Has anyone found the vMEM measuring points for the 5770????
Also hard mod for the 5770???Seems 1,35 is too little for 1100 core :P
I found them!!!Here are some measuring points for the voltage on 5770!GDDR5 get 1,6ish volts right???
http://img11.imageshack.us/img11/7663/vmeasuring.jpg
hard mod is the same as for the HD4770 and vmem is measured best at the small smd capisators around the mem chips adn i can do 1100mhz core at 1.312v on all my 4 cards
1100?????WOW what brand and what bios is this on???Also did u measure the volts with a multimeter???
it is saphire all 4 cards and yes it is measured in afterburner if u set it to 1.35 i get 1.39
i cant seem bench over 1040/1420 stable...U are very lucky on 1100 man!!!
This is probably world exclusive!!!5770 CAP MOD!!!
The card works but i have yet to confirm any stability improvements during HIGH OC...Maybe i need another 3 caps added...And some 16volts on the input too...Will update soon!

I'm not an electrician, but afaik caps shouldn't never put to a long wire.
Woow , what clocks can you manage with the cap mod ?
Theorw, ok then :)
When you do this mod with wires it dosent work nearly as god as witout because the caps have to be as close to the solder point as possible to work proberly.
The thing on this card that neds caps are the memchips i will do a full mod on one of my cards soon to try if there is any affect
trust me wires are no go i have cap modded cards for over 8years and wires dosent help and i mod psus and hifi and carstereo and trust me wires are no go.. the thing a cap does is to provide current lightning fast to the circut and with wires the current mett alot of resistance and the effect goes away
Look what i did with a HD3870 card..

@RISKA
It makes sense what u say about the resistance of the wires...maybe i should put them on the top of the other caps or could i leave 1 CM of wire???Say the CPA had REALLY long legs????????
can any one tell proper voltmod for 5770 (GPU & MEM) :)
1120 1.32 Easy passed all 3dmarks

sweet thanks :toast:
i was able to do this on less then 1.25 i think that was the highest with 100% fan speed
http://img.techpowerup.org/091108/P12118.png
So the core did scale nicely under cold hiwa? in a week or so im putting it under dry ice, due to the lack of a dewar atm.
you think your vmod was more stable then the softmod? or why did you mod it..
scale 60MHz air to chilled water 15°c with same vcore
i think subzero u can go over 1200 without problem
i never used softmod :D if i can hard mod it ;)
can any differ
what is pencilmod ?????
&
what is vmod ?????
Im confused :s
Never done it but will do with this card ,when it arrives :D
a 50khom vr is fine and it will give a boost to vgpu around 0.050-0.075 v at stock
I measured the resistor.turned out 2,1*k so i used 100k that i had in handy.Turned out it worked and the volts were really stable in comparison with the volts the chip would output...Too bad the cable broke off and for a moment my card would reboot and i thought it was dead1!!
Tomorrow i am gonna put it back on and see what i can get!!!
http://img4.imageshack.us/img4/7822/dsc01907t.jpg
Theorw, did I get it wrong or You turned 100k VR to 2,1k before soldering?
Theorw, OK sry, I read wrong :)
well i resoldered the VR and i tried some OCing today.What i found out is that with the VR configuring the volts,the voltage is extremely stable like 0.002 change during gameplay...
I managed to have 1000core on 1,298-1,301 volts while on softmod i set 1,264 but it was actually more that 1,31...measured with DMM.
So when u say i have 1000core with 1,2volts its more like 1,25...
The most important think i found is that after some voltage,i dunno what exactly yet the card wont post!!!I mean i left the VR set to some middle resistance and the card wouldnt boot but after i set it a bit higher it booted no problem.
Do u think there might be some OVP the chip does?????It was higher than 1,33 i think...
i tried up to 1.40/1 and didn't catch OVP :D
over 1.35 no gain in my case need cold to found the limit
tweaked my windows 7, but still getting like 1/2 fps less on GT3 then xp, same clocks.
really odd... ill try some other drivers aswell
Well i cant seem to pass any 3dmark @1040 with the asus bios.I hardmodded and i have ultra stable 1,349-1,352volts core but i cant pass 1040.
This is strange though cos i posted on hwbot 27k on 3d05 @1040 with the stock bios but cant find it now...
I might have the crapiest 5770 for OC...:(
Whta brand is your 5770?can u post your bios please?
I can run mine @1400 without problems stable but i have heatsinks on the back side and a 230mm side intake!!!
u guys dont cool your chips???
I saw in a russian review that mem chips get 90 degrees on stock!!!

120mm fan 3000RPM on back memories
Thanks pal!Nice idea with the 120mm!!!But its ghetto:P
Mine is neat!!!
i can run 960/1445 totaly stock.
my score's are quite low :(
45k 03 stock
52k 03 oc'ed
15k 06 stock
16k 06 oc'ed
Well your scores are OK!
Its your CPU that needs the boost!U need at least 0,5 GHz more to have bigger scores...
I have 4,5ghz and i get 58k so that our difference...@1000mhz core but 40mhz dont give 6k more...
its not the rig in my sig.
i'm running a E5200 @ 4.1, ddr2 around 700mhz with loose timings.
really need to get a new setup, this sucks.
Has anyone tried 6ghz mem ? i read some reviewer managed to get it up to 6 but they didn't say anything about bench stable.
w1zzard from techpowerup manged 6ghz and said it was bench stable.The average OC on the mem is 5600mhz...(1400)
I have tryed cold air on to the mem and it helps alot did 1525 stable on default vmem
really?Cold air via what?A/C?
No big fan and open window and outside temp at 2-3c
Funny !!

Theorw
Adding extra capacitors is for lowering ESR (series resistance). More caps > more energy stored > more current ripple can be filtered. If you add caps with long wires, + thin wires => you will add MORE parasitic resistance and noise to power planes, that without caps. It's totally stupid idea, to use that long wires from you first pic, sorry :)

guys please help me out
Mine is Sapphire 5770 & where to what to do ??? > vmem,vmod :)
http://i560.photobucket.com/albums/s...ack_full_2.jpg
mostly i need vmem
http://i560.photobucket.com/albums/s.../5770/vmem.jpg
& vmod
http://i560.photobucket.com/albums/s.../5770/vmod.jpg
Vmod GPU is same as on HD 4770 because both cards has got same controller L6788A. (Datasheet)
http://img204.imageshack.us/img204/3562/37838159.jpg/
Vmod MEM is realized by controller uP7701 (Datasheet)
http://img265.imageshack.us/img265/7474/42432452.jpg
If i am seing wright you have to mod both controllers for mem because ther is one for both sides!! correct me if i am wrong..
I don't think those control Vmem
http://www.xtremesystems.org/forums/...2&postcount=11
or maybe
http://www.xtremesystems.org/forums/...63&postcount=2
I havent tried any of them yet.. but tempted to
My card won't even do 1000 core at 1.3v :(
thanks for ur quick replay :)
some one correct this please
i have really not tried OCing this card ,but my card is @ 950/1300
^^^ please make this a proper vmod & vmem thread for HD5770
Theorw has soldered some caps on his cards ???
IMO- Using caps with wire leads is not bad if done properly at all..in fact the added ESR from using wire leads is next to nothing, especially when you consider using high uf caps with a low voltage. The amount of additional filtering introduced to the power circuit is still way beyond that of stock ESR values. For example:
Using SMD caps gives the highest amount of stock ESR value over all other types of caps...
Using caps with a lower voltage rating [closer to that of stock vcore], will have a lower ESR value than those with a higher voltage rating
Using a high uf rating ensures low ESR
...So obviously, it would not be in vain to add 4v, 750uf caps to a GPUv circuit...and use wire leads. The amount of added filtering is still beyond that of stock capability.
useful info I found here: http://kakopa.com/ESR_meter/index.html
*I have capped plenty of GPU's myself..and adding electrolytic caps to a GPU circuit regardless of method can bring benefits when done properly.Quote:
A capacitor which is working at 100 KHz and is 2000 times smaller is going to have an ESR which is ten times greater and is going to generate much more heat in much less space. Miniaturization tends to increase ESR as well as impede heat dissipation. We can see everything here works against us.
Right after i opened the card,i found out that the resistor C304 is connected to the leg of the memory controller and then to the ground....So its the pencil mod right???
HOWEVER WHEN I SHADED FROM STOCK 5,17 TO 4,44 KOHMS i saw no increase at all!I am gonna try shading the other contrell together and see if something happens.If not then probably we should do as shamino says...
USE ON YOUR OWN RESPONSIBILITY!!!
OK GUYS just did some testing and found the PENCIL and HARD VMOD!!!!
Its the upper uP controller that manages the vMEM.
http://img27.imageshack.us/img27/2151/pencilmodl.jpg
Default value of the RED circled resistor is 2,35kOhms.
Shading with pencil to 2,13 kOhms went from the stock 1,618~20 to
1,628~30 idle and 1,640 LOAD!
So doesnt this make it and OFFICIAL PENCILMOD?
And of course the green lef to the ground with a 20kohm VR is the GARDMOD right????
Any corrections accepted.
USE ON YOUR OWN RESPONSIBILITY!!!
Where did you measure the voltage?
And did you try to measure on the front mem with that first try?
I measured in the SMD caps located NEAR the chips!!!Dont worry!!
No i didnt measure the front memory chips BUT I MEASURED THE R301 resistor that is in contact with the leg of the OTHER uP controller and it was 5,72 kOhms so i dont think that the controller apropriate for the back side chips would give different voltage and therefore have different resistor RIGHT???
But for the hell of it i am gonna solder and measure the front side chips too!
Wait 10 minutes!! :D
thanks man
Well it wasa A PAIN IN THE *SS to solder in the front cos of the mem heatsinks but i managed to do it and i verify that it is the same on both sides of the PCB!
Somebody YET has to verify thsi mod too because its better when its cross checked right???????????
USE ON YOUR OWN RISK!!!
EDIT:1 little problem though...I had 2*20kohm VR s soldered to gether from a previous mod and i put them in this mod BUT i didnt notice any increase in the volts except i now have 1,635 LOAD instead of the stock 1,620...
Strange.I am gonna put a regular 100k soon and check again....
EDIT No2:i CHANGED THE VR BUT THE PROBLEM PERSISTS...So i am having doupts about the hardmod...Pencil mod work great though!
If the mem control IC's have different resistances..then they are most likely for vDD and vDDQ...just like the 5850/5870's..having 2x separate voltages for core and driving voltages... Seems to me this would be more logical, than thinking 1x controller for each side of the PCB..
I think so too...So we want to change the vDD right?
My successful pencil mod shows that the uper controller is for the (vDD?)
The thing is that i think i need a very small VR like 10kohm...
I try tomorrow...Off to bed...
Yes..increase in vDD for mem OC..only slight bump in vDDQ is really needed if anything..doesnt really increase clock potential a whole lot, from the OC's I have seen..
Are there also people here that have mod a 5750 ?
I already own a 5850. But i like to play with hardware :) but i dont want to risk my 5850 just yet :D so i was thinking of buying a 5750 to have come oc fun.
And what kind of gains do you see with the cap mods ? do you also see improvements at lower voltages ? or is the gain bigger when you use it in combination with a v-mod ?
Edit:
I dit some research and i now know why people take the 5770. I thought the 5750 also had 800 shaders active but this is not the case. And off course the stock cooler is better. But i find the 5770 to expensive compared to the 5850's.
Yes dut 5750s price doesnt justify the difference from 5770...
Its like 10-15 euros here with which in 5770 u get far better cooler,voltage regulation AND 80 extra shaders...All this for 10-15 euros...
So i think that if u want vmod and experiments then 5770 is the ONLY way!!!!
Can someone explain the VDDC CURRENT%OCP value in the shot ?What deos it calculate?Maybe when it reaches 50% the card shuts down?I heared that this happens on 1,7volts...AND WHY DOES IT GO UP AND DOWN in regular intervals???????????
iN 1,34V THE VALUE WAS 42%.i INCREASED @1,4V and the value went 45%...Didnt want to torture the card but is there a way to determine the AMPS the gpu consumes by this value?
http://img9.imageshack.us/img9/6796/currentg.jpg
45% + 1.4v = 2v ...I dont think you have anything to worry about..Your screeny doesnt show any OCP value that I can see...am I missing something? The only value I can spot is your GPUv...which says its at 1.12v..a long ways from the 1.4v you stated...
OCP works off of hysteresis ...so changing VID bumps OCP...but with these Voltera IC's it appears that VID does NOT change..only GPUv..so VID/OCP limit stays the same..Have you tried to see if the OCP mod for the 5870 is the same as your GPU..?
Yes u are missing tha i hardmodded the card!!!
I dont use software i mod with a VR!Far steadier!!!
2)How do i do that?
From what i saw u need to remove a resistor completely and then solder a 18kohm one right?But 5770 has different volt chip...What leg of the chip was the 5870 resistor connected to???
So i could search my chips datasheet and experiment...NO WAY I REMOVE THE RESISTOR THOUGH!!!!DID U?
Well..according to the datasheet, OCP is set to trip at 140% of stock VID..
I marked the pin for OCP..and the pads most likely linked to it..you will need to confirm they are connected though.
http://i265.photobucket.com/albums/i.../5770vcore.jpg
Thanks man!Will confirm as soon as i can!
Here is the points for the ocp mod .
The leg on the ic is connected to a smd cap and not the resistor to the side but the little cap
