Asus HD5850 Direct CU no voltage tweak

[Geckx]

Hi all,

I've owned a reference ASUS HD5850 from release and been using happily with Afterburner all the time. Everything works perfectly

Now I bought a used Asus 5850 for CF (or second rig). This is an EAH5850 Direct CU edition. Apparently non reference design. I saw it when installing the card. The first had 2x6pin, the Direct CU has 1x6+1x8pin pci-e connector.

I installed the card and wanted to see how it compared in OC'ing with my old one. But I can't adjust the voltage with afterburner! Googe tells me that I have to use the infamous smartdoctor. I prefer not to do that. Furthermore smartdoctor has no decent voltage monitoring and I want to lower 2D volts, but I can't see if my bios flash took effect... (if anyone knows the vGpu + vMem readout points on the card pls tell!! I have a dmm)

Does anyone know a fix for this so that I can monitor + adjust the voltage with Afterburner? (Yes I enabled it in settings and yes also via cfg)

Thanks in advance!

You can't, you'll have to use smartdoctor like Google said.

That is what I was afraid of...

Any chance of support in future versions ? Or is the card already too old to bother. :p

And what about voltage readout with multimeter?

It's not the age of your card it's because yours isn't MSI. I can't adjust voltage either unless I use Sapphire Trixx.

GPUCapsViewer or GPU-Z will display your voltage in real time.

My other 5850 works with the voltage control from Afterburner. And that's also from ASUS.
I believe this one (Direct CU, same with TOP version) is not because it isn't a reference pcb. ASUS 'improved' it and changed the voltage controller as well..

GPU-Z only gives me VDDC offset. No actual value.

But that GPUCapsViewer does the trick! Didn't know that proggie yet. I can now monitor my voltage effectively. Thanks for this! If there is a rep system here you earned it ;-) +1

Thanks.

And yeah I should of said non-reference instead of non-MSI...
