did this mod work? i have the sapphire board wich is slighly different, but i hav located the vgpu control chip wich is the same, and the spot to solder is the same aswell.. but i need to know if it works.

do you guys know how to force ati powerplay to work on this card?

**3Deye** · 06-09-2009, 08:28 AM

Nice mod Risky,

How do you locate the VGPU control chip?

**Riska** · 06-11-2009, 06:50 AM

Ati powerplay works great if it dosent work on yours it is the driver there is something wrong with

**ninong** · 06-20-2009, 04:18 AM

Riska, thanks for the reponse. i've tried the past 3 driver versions (9.4,9.5,9.6). mine's a ddr4 version, could that be the culprit?

one way to confirm that ATI powerplay works is to see if the gpu clock goes down @ idle right?

**Riska** · 06-21-2009, 10:45 AM

Yes all of mine hd4670 clocks down to 165/250mhz

**ninong** · 06-22-2009, 05:33 PM

there's something wrong with mine then

probably have to do with the card manufacturer's bios..i might try to use the saphire gddr4 bios

thanks

I would give it a try

**ninong** · 06-24-2009, 07:00 PM

i'm new to this gpu flash bios thing..i'll prolly wait until i buy another cheap graphics card before i do this

i'm gonna use that sapphire bios that has the gpu clocked @ 750 mhz (stock) and ram @ 1100mhz.. mine is at 750/900. i tried OCing it using ccc and it passed stress tests & 3dmark @ 800/1050 (ccc's max), however it random crashes @ idle while i'm browsing the net & stuff. i tried 750/1050 and the same thing happens. i'm beggining to think it might be caused by rivatuner & catalyst 9.6 not being compatible with each other because the crashes dont seem to happen when i dont open rivatuner..so i'm now testing older drivers that work with rivatuner since i cant OC the mems to 1100mhz using CCC.

my card is a reference ati hd4670 ddr4..but it came in a box marked triplex hd4800 series lol. the card itself has no brand markings, just ati and stuff.

the sapphire gddr4 hynix chips look like this:

i dont have pics of mine but the markings of the hynix chips are like this

HY5FS123235A
FCP-09 751A

as opposed to the sapphire models that have this:

HY5FS123235A
FCP-08 816A

are those the same chips? also, any important tips before i do the bios flash?

thanks

sapphire's ddr4 bios didn't work, no display

guess i'm stuck to RBEing my card's original bios

**Andr3az** · 08-28-2009, 01:40 PM

Does anyone know if this works with Gigabyte 4670 too?

**Riska** · 08-28-2009, 02:12 PM

If it is ddr3 it is the same mods

I've got a question about this mod.I believe that the right modd helps Vcore.The left is for Vmem?If not ,can a single mod (either the left or the right)can work without the other.

Thanx in advance

**largon** · 09-12-2009, 06:58 AM

You don't need both, you can do either mod without the other.

**ToxicWk** · 09-12-2009, 08:00 AM

And both are for Vcore right?Or right modd for Vcore and the left is for Vmem?

**Riska** · 09-12-2009, 08:39 AM

Left are vmemmod and right are vgpumod

**ToxicWk** · 09-12-2009, 09:09 AM

Thanx m8

The one to the left is mod point but just try with your multimeter and check the point to ground

This is what my 1Gb card looks like.

I also moved some caps etc to the back of the card, so I could mount my pot.

I've mods done for ASUS EAH4670/DI/512MD3 <- there's to versions of 512mb cards from asus, this one is with spiral cooler.

**Splave** · 09-27-2009, 07:23 PM

If my eyes aren't made from wood it that chips model is uP6201, looks like 7 but that one uses different package.

Anyways, pin 11 is FB, measure resistance between GND, caps - leg or from fan header. Should be something around 2.4Kohm.

Here's some pic. if these are correct 100K Vr between FB and GND ^^

**Splave** · 09-27-2009, 08:23 PM

can I measure from that resistor to ground or does it have to be from FB to ground. Not sure I can get my lead to single the leg out.

fb to ground im getting 17.33 m ohm
