NO limit ! u can push GPU Voltage up to 1,99V
maxibition says that in post #163 ...
no doubt that cant be healthy
but a member testet sucessfully 1,3v on a 4870 @888mhz gpu score
see link below

I personally wouldn't mind seeing a picture of a DMM showing the coinciding voltage with whats set in the program though, sorry to be skeptical. It's just that I trust a DMM more than any software monitoring tools, especially at the higher ranges... Wasn't 1.3v still within BIOS range on the HD4870 anyways?
Nice find though man, I'm sure a lot of people will want to try this out!

software isnt exact at all..
and to be skeptical is much better then skrew up your cards
nothing beats a professional mm - no doubt.
i even read a post that this mod wont fit with 4850s cause they are not equiped with digital mosfets !
so if your gfx got uP6201BQ voltage Regulators... forgot it.
back to the 4870s - another poster got sucessfully 920 mhz core clock , but i dont know the voltage.

770MHz at 1.26V is... Impressive. I'm having a hard time getting 790MHz at 1.42V with my dual slot Sapphire. Oh, and yes, I managed to mod it successfully.
EDIT: Seems it just goes on and on ever since I got above 1.4V, 815MHz seems fine so far. Just testing though, the only requirement is 3DMark06.

Just got my 1GB HIS card under water and got one of those Zalman VRM coolers. It works VERY well, VRM load temps around 50ish and idle 30C!
A bit annoyed that this card has crappy Hynix memory. Which manufacturers use better stuff?

I'm not exactly sure, but isn't Qimonda the best GDDR5?
Seems the blue Sapphire 4850 is utter crap, I could do 800MHz flat, but 830 didn't work no matter what I fed it with (which was up to 1.58V under a accelero twin turbo). Yes, I'm aware that those kinds of voltages are prone to kill the hardware, but I just wasn't bothered with keeping it alive.
My reference (old) Sapphire 4850 is better though, running 3DM06 at 800MHz with 1.3V right now (just thought I'd start there, haven't tried any less voltage).

I had a blue 512mb Sapphire once with the analogue vrm circuit and it did 850mhz stock voltage under water....my red Sapphire with digital voltage reg circuit did 875mhz stock voltage though....not found another 4870 that clocks nearly as well

Just thought I'd add my results in here. (By the way, that Awardfabrik program does NOT work on ALL 4850s)
I have a pair of Asus 4850's that come up in GPU-z as "Prerelease" which I don't know why this is the case, but they are pretty early cards I guess.
Testing each one individually, aircooled with Thermaltake DuOrb.
Vgpu under load is 1.29v, my max 3d06 runs last night were at 875 on both cards with the same 1.29v.
Max in 3d01 Nature (my quick "does it bench" test) was 900 core on one card, and 895 on the other. I was surprised when I read the voltage (with a DMM) and kept cranking the core up 25mhz at a time and it just kept staying stable! Fun cards

Hey there,
i got this card yesterday:
http://www.abload.de/image.php?img=dsc02565uall.jpg
i think its a rev 2 pcs+. But the vgpu measure points that were posted here do not apply to me somehow. If looking on the back of the card, i have 1,3v reading on the right points to ground, on the left points as stated in this post
http://www.xtremesystems.org/forums/...postcount=1317
i do not get any readouts...
now my pronlem is: unfortunately, voltages do not alter in powerplay mode (if i measure on the right hand points), nor can i adjust them in bios. Someone has experience with this card? Its a powercolor 4870 pcs+ 1GB, obviously with analoque pwm section...

Hahahaha, I love these HD4850s! Managed to push them both to 880/1050 last night (1,48v), and now have the highest scoring 2x HD4850 CF system on HWBot with 3DMark Vantage:
http://hwbot.org/result.do?resultId=825097
This gives me a nice 3rd place on the overall rankings and the first two users have 3 and 4 HD4850s respectively so makes sense I guess!
Whats the limit people have been pushing these cards on Vcore for benching purposes? My EK waterblocks are keeping both cards under 50C load (gpu, mem and mosfets!) so temperature shouldnt be an issue...
Thanks!

will i with pencil mode raise mvddq and mvddc(at least that is shown with picture at techpowerup)?
so if i all get it clear i need to reduce resistance of r713 and r913 versistor??
stock resistance(i measured with DMM) is 220ohm each, for how much i need to reduce it??

i need some help brothers :p
i understand VDDC for the 4870 is the Vgpu mod
and MVDDC is for the Vmem mod
but what about the MVDDQ ? i cant find out what it dose :p
and i really want to know.. i'am waiting one sapphire 4870 tomorrow an when i will fined the max clocks on stock voltage i'am going to mod it so i need to know what the MVDDQ stands for...
thanks :p

MVDDQ (VDDQ) is the 'chipset voltage' of a GPU (as compared to a motherboard).
Some claims that raising this improves the OC of both the core and the memory. Vddq had to be raised together with the Vddc to have any effect. Vddq was a 'big thing' back in the 9800 pro/xt days. Haven't seen it used since then. It had only a slight impact even on the 9800 cards.
Don't bother, I managed to kill two 9800 cards - both likely by playing with the vddq.

isn't the pcb different from the one in the image at the beginning of the post?
thank you,

I didn't care about VMEM, so I can't say much about it.
