A couple of months ago I purchased a reference HIS 4850 512 from newegg. When I received my card I noticed that it was a reference design but it was a blue PCB and on the front it is missing some capacitors. I put an AC-AS1 on it with Enzotech ramsinks on the ram and vregs. I used RBE to edit the bios and give it 1.2v but my highest stable OC is only 650/1050 with load temps of 44C @ 24C ambient. Anything over 650/1050 it will do a VPU recovery. :(

I was disappointed with the OC but I'm planning on volt-moding the card in the next few days. So I'm hoping with a little more "vitamin V" I can OC it more. I have already soldered on test leads to check GPU voltage and MEM voltage with my DMM. I measured 1.2V for my GPU @ load and 2.05v for my MEM @ load.

My question is, does anyone else have this "weird" reference card with a blue PCB and about half as many capacitors? And what kind of performance are you getting with it?

I haven't taken pic's of the card yet. This evening when I volt-mod the card I will take pic's and post them.

All of the pictures of reference 4850's I have seen they all have red PCB's.

The blue rectangles outline all of the cap's on the stock reference card. My card came with same cooler but with about half as many cap's and a blue PCB.

Thanks again for the help, and this evening I will post pic's of my card.

Is this what you are referring to?

Not sure what to make of the missing caps as you can see where they are supposed to be.

YES! TY CGR! That is exactly what my card looks like. Except mine came with a reference cooler.

And I'm not sure what to make of the missing caps either. You can see the outline of them. I'm wondering if the missing caps are the reason of my card only being able to hit 650/1050 on 1.2vgpu...
