Not yet... As jimmyz said, this is not even done with testing yet...
You'll hear directly from him and W1zzard when it's complete (read: safe).
We're still poking around at this point.

ummmmmm the chip to do the vmod is on the front.. i wish i could just read the chip. or at least have a card.. might have to grab one as well and slang the 4850 after i finish making a PWM circuit for her......Not yet... As jimmyz said, this is not even done with testing yet...

How were you planning on doing the pwm mod? Just attatching another PWM ic with the current one?ummmmmm the chip to do the vmod is on the front.. i wish i could just read the chip. or at least have a card.. might have to grab one as well and slang the 4850 after i finish making a PWM circuit for her......
yea basically make a separate circuit on some waffer board, some mosfets..... direct attach to the feed for gpu..

my 4850 is doing only 850@ 1,45V
its a bad core i think
on stock only 670 oO
my ram does 1175 @ stock
but for extreme oc on ram i need water on it
i have tested 1300Mhz @ 2,4V on passiv heatsinks and i think its to hot i get extreme artifacts

Hi there
What POTs may be used for VCORE and VMEM ? i have one of 1kohm, one of 10kohms, 2 of 20kohms and one of 50kohms
Regards
You use a 100k pot for both the vmem and vcore. Happy modding.
cant be dif from 100 :s?
It could be higher, but i think anything lower will result in a stock voltage that is to high. But i am not sure, you might want to wait for someone else's response.
@weirkved
please read this. it will help.. and to anyone who is new to vmods.

here is mine. Sorry for the low quality
I tried the 20K vr recommendation by VR Zone for both Vgpu & gddr on 4850.
Works fine using 20K vr.
Vgpu measure
Vgpu mod using 20K VR
Vgddr mod using 20K also
4870 uses same Vreg as 9800GX2 and GTX 280, I am looking for VT1165MF data sheet, hope no NDA on it.

Could you post a link to that guide? as i am a little confused about the pictures.
why thanks. looks like the one in the first post of this thread, just using lower trimpots, and one less solder point to the PWM.
why change voltage destroing warranty, when you can do it via bios edition with RBE_111?
Changing the bios values will result in a maximum of 1.21volts, which isn't as big a gain as some would like.
... you posted the same question in 2 threads...
why do i hear an echo? lol
I don't think some of the people posting are reading the whole thread.
Alright, I've tested my HD4870's VGPU measure points and just holding on for the VGPU mod. . .
Got it all under water at the moment and BIOS moding doesn't seem to do alot since I don't know what the maximum VGPU values are for BIOS mods.
I just wish it was as easy to mod the voltage as it was on my 2900Pro, where the BIOS allower for some pretty hefty voltage increases.

4870 vgpu bios mod? default 1.263v
