Voltage Regulator

PAPADOC · Aug 23, 2009

Great , from all the 4890's I had to buy one that doesn't have the reference design hence NO Voltera 1165 chip. Does anybody know what chip this crappy XFX card uses? and if it's possible to raise the core voltage?

Thanks!

:mad:

Take pics, give a link.. something.. Need more information for sure. All I know so far is that it's a crappy XFX 4890 by your description. :ohwell:

Have you tried using GPUToolto raise the voltages?

ObSo-1337 · Aug 23, 2009

I have an XFX 4890 XT and i can raise the core voltages easily. Use GPUtool

No Voltera chip on XFX HD4890

Ok I tried doing the mod as per this url--> http://vr-zone.com/articles/increas...-hd-4890-using-rivatuner/6880-1.html?doc=6880

and I got this error (see pic: Riva Error) when i tried going into "hardware monitoring"

And when I opened the Bios in RBE (see pic: RBE) the voltage registers are grayed out.

AAAARRRRGGGGHHHHHHHH !!!

XFX SUCKS THE BIG ROCKS :banghead:

That or a card that keeps the reference design hence has the Volterra 1165 chip

I know the diamond has ref. pcb and asus gives you their software that allows to raise the core voltage.

in this thread you stated the you could raise the voltage with gputool... How did you accomplish that..?
I just received my xt and I have no voltage option in GPUTOOL.... I tried RBE and Riva and I get the same message as the first guy...
Can anyone please help me?

Most likely your card is bulit on a non-softmod compliant non-reference PCB.
Do you have a pic of your card? Or can you find a review of a physically identical card?

Would you mind showing us which card you picked up :laugh:

Then someone can maybe help you, or tell you for sure if you are screwed.

LOL... I got this one: http://www.compusa.com/applications/SearchTools/item-details.asp?Sku=P450-4892

I think I am.... :banghead:

It looks like they changed the card part way through the run to one without the volterra. So does look like your screwed, can't you return it if you just bought it. If not thats why I always try and use Newegg

4890 xt errors

My gpu get's errors in manufactures clocks...

Would this be grounds for a RMA?

OCCT GPU bench = bad.

Reefer86 · Sep 10, 2009

i have a xfx standard edtion clocked at 1000/1000 and i was able to raise the clocka nd voltage. the diffrence is that xfx released new cards with a diffrent design on the cooler and with that changed the VRM chips on the PCB. i suggest you go find a seller that has the V1 reference cooler, or check with your supplier before you buy, or maybe so your homework before you go xfx SUCKS.......
