cgminer 2.10.0 + Radeon HD 4550

[AwkwardSituation]

I think I may have already read somewhere that the 4000 series isn't supported by cgminer anymore, I know it has weak ass hash rate, but given that I have one in the systems I'm CPU mining in, I'd like to at least get a few MH out of it if possible.  Anyone know if cgminer will work with a Radeon HD 4550?  I haven't been able to get it to run.  I'm running 2.5 SDK but when I run cgminer the program immediately quits and Windows 7 x64 gives me the generic windows error that the program has stopped working.

Using --verbose doesn't help it crashes before it starts logging.

Any ideas?

Thanks.

Typically cgminer dying instantly when starting up means your settings are incorrect. i would make sure i have the latest amd/catalyst drivers (with open cl) first. Feel free to post your CONF here (edit out your user/pass for the pool you're working on please). I'll help as much as i can.

the 4550 uses 80 shader stream processing units. However, i don't think it supports the new opencl (the 4450 was released with opengl, and prior to the first stable version of opencl). Could be a complete hardware incompatibility, or could just be a setting.

[AwkwardSituation]

Okay right now I'm downloading AMD Catalyst 13.1 and I will install the AMD-APP-SDK-v2.5-Windows-641 drivers and see what happens.

[AwkwardSituation]

Bah, I tried the latest Catalyst drivers and 2.5 sdk install and it still craps out on me immediately.  Here is my cgminer.conf file.  I am calling it from a command line by navigating to the directory containing cgminer and then entering cgminer -c cgminer.conf

Code:

"pools" : [
	{
		"url" : "http://api2.bitcoin.cz:8332",
		"user" : "myWorker",

],

in your conf file, slush's pool hostname is incorrect (you have a 2 after api). im betting this is why it crashes instantly.

slush's pool settings:

http://api.bitcoin.cz:8332
(Default URL for Stratum and Getwork miners. If you're unsure, use this URL.)

or
stratum+tcp://ipv6.stratum.bitcoin.cz:3333
(IPv6, only for Stratum miners)
or
http://pool57wkuu5yuhzb.onion:8332
(anonymous mining over Tor network)

Nah the pool URL didn't fix it.  Must just be incompatible with CGMiner....Oh well, thanks for the efforts bud.

I assure you cgminer is compatible with slush.

Do you really have 4 GPU's in your system?

I managed to mine with Phoenix 2 on this GPU.
Try that.

Okay I will try Phoenix 2.  What version?  And what MH/s rate were you getting?

[Parazyd]

Just try. There are various configs. Write your own and see what you'll get.
