4870 Overclocking Thread

[AriciU]

Does AMD GPU Clock tool work with two cards and 8.7 beta? I get SET CLOCK FAILED for the second card.

Anybody here running the HD4870 on a 500W PSU? I want the 4870 but I'm not sure if my Antec EA500D 500W PSU is up to the task. I have 1 DVD-RW and 1 HDD, 4GB DDR2 800 RAM, E8400, and Antec 900 with the 4 stock fans.

I do. CoolerMaster iGreen power 500W (33A on the combined +12V). 1 HDD + rest of the config in sig with the HD4870 OC at 840/1000. So far no issue

I'm running a Antec EA500 with an HD4870, 1 hdd, 5x120mm fans (beefy ones too), E8400@4.0Ghz, and 4GB ram with no issue. I have the earlier non-D model but I imagine you'll be just fine with your configuration.

Your sig hasn't been updated for the HD4870 you have.

I think the non-D models are made by a different manufacturer than the D ones, although it's unclear if performance has changed, since there are no good comparison reviews.

Glad to hear I'm not the only one with that problem. I'm using a Biostar IP45 mobo with a pair of 4870 in Crossfire. Card in slot 0 gets the same "fail" message but the card in slot 1 clocks up without any problem. Is there a driver version that works better with AMD GPU Clock Tool? Is there another GPU overclocking utility I should try?
