OpenCL on Radeon HD 4200?

candreasen

I have been trying to get setup Bitcoin mining on my pc while I'm gone and it seemed like was going to work but even after installing the latest drivers and then the individual OpenCL driver no miners would recognize the card(integrated Radeon HD 4200 as previously stated) seemingly because the card didn't use OpenCL and so I looked and some people said the card didn't support OpenCL but I had just downloaded a driver specific to my card specifically for OpenCL.
Anyone know whats going on?

Thanks,

The 4000 Series does not support OpenCL. Only the Radeon HD 5000 Series, 6000 Series and any future products.

candreasen

Oh odd they have a driver for it then?

Thrax

The OpenCL driver only enables support for compatible architectures.

candreasen

So why have it available for non-compatible architectures?

Thrax

AMD and NVIDIA both release what's called "unified drivers." These are complete driver packages that dynamically enable and disable software based on what's supported by the GPU you're installing to.

You're missing the point: it's NOT available. The Catalyst driver is an "all-in-one" driver that packages support for a whole range of GPUs. If you happen to have an OpenCL supporting GPU, it will install OpenCL support. Would you rather they offer different installers for every architecture? No, neither would I. A single installer for their entire product line. Makes sense to me.

candreasen

I see but still there is an individual driver for OpenCL as well.
On a side note would a CAL based miner work on this card?

Thrax

A driver still doesn't mean anything if the architecture doesn't support what the driver enables. The driver is for people who want to specifically enable OpenCL support on 5000 and 6000 Series cards; it's a smaller download for people who have a graphics driver they're happy with already installed.

AMD CAL is also for 5000 and 6000 Series.

Oh that sucks, is there anything that I could use my graphics card with to bitcoin mine?

primesuspect

No, you'll need an upgraded video card, which would solve two problems for you ;)

candreasen

Kinda sucks since this computer is under 1 year old.
Also any reccomendations that would run a fairly new game on low graphics with at least like 25-30 FPS?

Thrax

Radeon 6850.

candreasen

Would that work well on a system with a 300W PSU because it recommends 500W on amd's site?

Thrax

No, it would not. But to be perfectly honest, any video card you could upgrade to with that power supply would not offer you a considerably better experience than what you're already getting. If you want better graphics, you'll need a new power supply, too.

candreasen

Would a 400W PSU work, I do have one of those in a different computer I could switch it for?

Thrax

I'd really recommend a good 600W PSU.

candreasen

Yeah I wish this wasn't necessary for a newer computer. I might look into that but I will probably just wait a couple years and get a new computer(one thats good this time).

Thrax

It's not typically necessary, but the PC you purchased is more suitable for office work, as opposed to gaming. :)

primesuspect

Thrax: Would the SAPPHIRE Radeon 6670 low-profile card be a viable upgrade path for him that wouldn't require a new PSU?

Thrax

Hmm, good call. It could be the right part, yes, but I get the impression that he might be looking for a little more performance.
