If they've not already been sorted out...
whos got a card and who wants to post up high-res pics of the PWM area so these cards can get pushed properly? :)

Whoa! All the mods are on the front!
I see a few options....and I cant narrow it down from pics alone :(
VT1165 not need hardmoding :) use rivatuner with volterra plugin
Is there two VT1165MF's? The one for Vgpu is hard to understand.
no support in rt yet for the i2c bus on those new cards, but soon

gputool working fine since yday .. gave test version to a few key overclockers
second controller is not memory voltage but vddci which is some gpu io voltage.. dont know all the details yet, but doesnt seem to do much for ocers
w1zzard, I remember hearing something about the RV870 having some sort of uncore, do you think it could be that?
second VDDCI voltage is VTT for core i think :rolleyes: ... on 4890 is increasing this voltage not helpful
You're joking about soldering a resistor that does nothing at all, right?
I know little about hard modding, so I was hoping that the 5870 would provide a simple soft-modding solution whereby a later version of RivaTuner would handle it. Is this the case, or is hard modding required on the non-Asus 5870's?
Oh I am excited about the voltmod possibilities for the 5850 mostly! I am hoping eventually when it drops in price I can make a little beast out of it.
Any news yet on hard volt mod :D for 5870 ?
should be a 5870 waiting for me when i get back to england on wednesday...
fancy letting another oc'er test that modified version of gpu clock tool wizzard...
i'll cross my fingers and hope you already have it up for dll by the time i'm back....:up:
I don't know much about hardmodding, however i found these images on the web that might help:

When will rivatuner support this? Any word?
..wonder what the empty plug position on the backside of the PCB was for..? What ever it is..its pretty close to the voltage control IC's..maybe some kind of 'commissioning plug'..?
*Its 'JU4000' in this pic
@ Largon.. is that vMEM controller near the JU4000, you think?
This is how I see it:
Attachment 97934
That missing JU4000 connector does have direct connection to the resistor network of VT1165MF GPU vDDC controller. I have no idea what effect it would have, if any, as the datasheet for VT1165MF is not available, as usual.
i agree with largon. but shouldnt there be some kind of "control" component for the memory ? or is that all inegrated in vt243 ?
@ W1zzard . will the gputool support the 5850 at sometime?
why gputool 0.0.0 doesn't work with 5850 but works with 5870... the 5850 as the same chip (VT165MF) as a 5870 surely it should work?
As all other Volterra converter parts (VT1165SF, 57SF, 95SF), a single converter can be controlled by a resistor network, but when there's two or more in parallel they require a dedicated controller. Those VT243WFs are "in single channel mode" as they serve different loads (MVDDC, MVDDQ). Same config can be seen on HD4890 where there are two VT242WFs. HD4870 has only one VT1165MF, for GPU VDDC, yet there are two VT1165SFs that convert MVDDC and MVDDQ. Those VT1165SFs both have an external resistor networks to control them.
What are default 2D/3D/UVD voltages on your card? Can you please run MSI Afterburner with /i2cd,70 command line switch to capture state of your VT1165 and post it here? If different power state voltage is edited on non-reference board, it can be easily fixed by modifying the database (I'll be able to post the instructions on modifying it after seeing the I2C dump).
vgpu mod offers limited gains thanks to ocp
if someone posts an ocp mod for 5870 it may get me interested in getting 5870 :)
Anyone know the V.Mem voltmod ?
Come on guys, show the love and share the OCP mod
Please!
http://www.benchblogs.net/?p=115
found that, can any one confirm that it works cause it looks a little shady
does 5850/70 suports softmod for both gpu and mem?
HA HA HA
ocp?
ovp?
no no no...
we are talking about ati here guys:up:
oh check this...

(wanna see full video?):p:
W1zzard, Is that successor of ati tool? :) Damn I miss ati tool, used to be my favorite gpu oc proggie
Got it ;)
OCP mod works. Depents on the card if it helps with overclocking though.
This will give you around 3A per phase extra, which is 12A in total. So not much but just enough for that extra push. :D
Higher OCP is not possible because of the design of the volterra chip.
some pics of GPU ready for shipping..
Added total of 8x electrolytic caps and 8x SMD caps..OCP mod ready for VR as well. I installed vmeasure points for input and all output voltages as well :D

http://i265.photobucket.com/albums/i...0/P1060428.jpg
..hoping for good results..this will be benching on LN for entry to Kingpin's comp *fingers crossed*
I have not figured the mod for GPUv yet..but havent got much time to play with the GPU under power either.
For finding the mod, we need to locate the point around the GPUv controller that changes resistance, when softmodding the voltage...
ie- measure everything for resistance around the control IC at stock...then use software to increase voltage...shut GPU down..repeat resistance check, looking for changes..
I have only mod'd for OCP..the rest of the mods are all capacitors.
Yes..when you change voltage via software, it seems only the 'FB' is being changed..and not the VID..as we know that changing VID also changes OCP. It stands to reason, that if only the FB pin source is being altered..then it will be the only point that has changed from stock value, once voltage has been changed....
As for the SMD caps..they are on the front side of the GPU, in the first ...on the row of SMD's closest to the copper sinks..I piggy-backed them to the existing ones...
*the 5870 has 4x input power phases for GPUv...with dual-phase ouputs..making a total of 8x output power phases for GPUv.
So if i get this right in my 5770 i should write down all the values that are connected with the FB leg of my cards I2C chip and then measure again after having changed the colts via software right????????
And for OCP mod u need to find and change the VID right?
I used some from old GPU's I have fried...and landing them to the empty pads is actually more difficult..the solder on the pads is freakin hard as hell..and doesnt play nice....its muchmuch easier to piggyback.
Well I was told the mem caps have made a noticeable improvement...the GPU was passed to the owner last night..and he made some prelim runs..at 1132/1400 @ 1.35v with i7 @ 4.52 ghz...wont really know about GPUv until he starts benching on LN with 1.4+ GPUv... Results are coming soon..
Thats w/out vmem? Do you think OCP makes any difference w/ 1.35V only?
Thats what I've done for now:

Yes..1.4ghz was without any voltage increase to memory...just capping 2x 6.3v 1000uf caps to each mem phase. Now vdroop measured at each mem chip has improved substantially...
* and no OCP wont matter below 1.35v
Would that 5770 still have 1GB of RAM on the PCB..? and a similar layout for the voltage phase?
*I am not sure if the 5870's issue was due to the amount of RAM on the PCB..or lack of capacitance in the vmem circuit. Soon as I mod a 512mb or 2GB version..I'll let you know though :p
Does anyone know vgpu/vmem mod for 5870?
wow with the 4870 etc the mods were out before the gpu's were now there still seems like a vmod is unknown
It seems that nobody want to share it... :(
Any news on a 5850 vCore mod?
bizarre... people are each day more egoist and scared. There is like 2 or 3 :banana::banana::banana:s that already posted pictures of their modded 5870 w/ censored mods. Any vmod I've done I posted clear pics to everybody.
Full 5870 mod has been posted in the thread right above this one.
HOWEVER - nobody has posted a 5850 mod yet. Anyone? Bueller....Bueller?
Can someone show, where is the HD5850 vgpu measuring point on the PCB?
@nickless: Try the SMD caps on the backside of the PCB (the lower bunch), left of "HIS S/N" sticker
http://www.xtremesystems.org/forums/...1&d=1261426881
yeah its been confirmed... OCP as listed works as well no need to remove the resistor just solder VR and tune down..
http://img405.imageshack.us/img405/3526/5870vmod.jpg
Here are my vmeasure points:
http://i265.photobucket.com/albums/i...s/voltages.jpg
and OCP as well..
http://www.overclock.net/attachments...t-ocp_5870.png
not the same thread..but heres 5970 as well...
http://img31.imageshack.us/img31/1748/vmod59701.jpg
..prolly get ban now :o
thanks!
Is there someone how knows where the vmem mod for the 5870 is??
Pretty sure mem voltage can be adjusted with the unlocked BIOS... seems the BIOS controls only 1x VRM..the rest are slaves, so there will be just 1x point for hard mod..havent found it yet though, as I dont have these GPU's... I just mod them for clients :o
WTF is that man?
No 5850 voltage mods why??? LOL
Cap-mod on HD5850 seems to be pretty much the same as on HD5870.
Here is a picture of the backside of the card: http://ht4u.net/images/reviews/2009/...d_back_big.jpg
Looks like HD5850 has less caps but this shouldn't be a problem, right?
Anybody here already cap-modded his HD5850?
http://www.techpowerup.com/downloads...tor_v1.24.html
now there is a new RBE editor and it have memvolt settings for the 4890/5870/5970 cards as well as gpuvolt settings
^^^ is it working last time i tried 1.23 with my 5770 died ........
Please do show some pics buddy ..................
What do you mean i can showe 1.7v to my HD5770s without a problem
no offense Bro
Just some info how it works :) ,what voltage should be set so that it never bricks etc etc .........................
for gpu 3d voltage use the 0X18 window
I have posted this some posts ago
sorry
No harm done mate
Just FYI the "Memory Voltage" option in RBE doesn't change the memory voltage on the 5870/5970 for sure.
On those cards there are only 2 software controllable chips, two VT1156MF's, the first is for the GPU Core Voltage ( Vgpu ) and the second one is that weird Vddci.
Vmem & Vmemddq can be changed only by hardmod.
Still working on them ( need to confirm that they work properly, I don't want to be the cause of RMAs :p: ).
One person told me that this should be mvddq/mvddc... I would test it if I still have the card.

How much ohm do I have to use? I can't measure it right now so..
Thanks CL3P20 ....
You're so right !

When does OCP kick in without mod?
I mean, how much voltage can i set, before protection kicks in...
Can i run 3D with ~1,5V without any problems?
It's the clock frequencies ( GPU Core frequency ) not the voltage that plays a major role.
If OCP kicks in on a reference 5870 it's usually after 1250MHz GPU freq, AquaMark 3 is good for OCP testing ( especially the last scene, during the big explosion ) [ massive overdraw ]
I see... Then it's easier to solder trimmer to resistor and tune resistance to 18K ohms.
Thank you.
Testing one MSI 5870(Non Lightning), with software ~1250Mhz benchable. OCP maybe? Must do OCP mod and then we'll see.:)
EDIT:
http://www.upload.ee/thumb/436513/DSC_5012.jpg
Yesterday i did the mod... Unfortunately didn't find enough caps , but will get some.:)
Sadly I couldn't realize OCP/OVP and vGPU for 5850, any possible light on it my friends?
I tested a few 5870's up to 1.65V or so, and didn't get any OVP.
OCP was needed for most of the cards to get 1300MHz pass 3D Mark03, Vantage & AquaMark 3.
OCP mod should be the same for the 5850 ( I'll try to check it out later to confirm that )
Any vGPU solder mods for the non-reference 5850's?? (They dont have the volterra chip so they don't care about voltage changes via bios or afterburner or whatever)
I could take a few pics of my Sapphire 5850 non-ref if needed.
I believe there is already a topic about each non-reference card already in this section.
Did you perform a search ?
If there's no thread about your sapphire 5850 then open a new one about it, and take some good photos with macro because we'll need them.
I looked around and i found the threads but the voltage regulator chips mentioned in that thread are not the same as the one on my standard sapphire rev. 2 :(
It's an NCP5395T that is used to regulate voltage for CPU's on motherboards, too. I just hope it's software controllable, does anyone know that controller?
