1  Other / CPU/GPU Bitcoin mining hardware / Re: How many cores on a CPU is ideal for GPU mining? on: June 20, 2011, 06:19:00 PM
My $0.02... You should have 1 core per GPU (and an extra core if you actually plan on using the computer while mining).

Let me guess: you are using Windows?

I've got 2 Dirt 2 codes with 5870 video cards. Do you really think someone will buy them here?
3  Bitcoin / Mining / Re: 6 5830 on 1 MOBO is it possible? on: May 29, 2011, 07:00:21 PM
You guys are so awesome in this forum.

I thought windows can only accept up to 4 cores, and linux up to 6 cores is that not true? If you can really run up up to 8 GPUs on 1 board how do I go about setting it up?

I am awaiting more awesomeness from this forum. Thanks guys Smiley

I got 6 cores running in Windows 7 (2x 5870 + 2x 6990). Linux kernel can be configured to support an even bigger number of GPUs, there is an option in kernel configuration for it. I'm using Gentoo and there are guides in the internet how to do it, I think that there are also for other linux systems (even if the process differs).
4  Bitcoin / Mining / Re: HD5850 @ 340Mhash/s on: May 29, 2011, 04:41:54 AM
Seriously, we're doing a dick size thing? I'm doing 368 mhash @ 918/305 on 1.088v, and its below 75c. And I haven't even modded the bios yet.
Yep. Mine is 385Mhash/s at 1GHz and 1.25V, 90C. Could make bigger, but I just like mine as it is.

ASUS Radeon HD 5850 overclocks pretty well with included Smart Doctor utility, pushed mine to 385 MHash/s. I use nVidia GTS 450 as the primary graphics adapter at the same time, a dummy plug works fine for the mining card (btw I didn't have resistors, so had to use just a piece of wire instead). In linux only hardware overclocking using a custom is possible (correct me, if I'm not right, I don't know gpu overclocking software for linux), so better take reference cars, or you may face problems flashing BIOS.

And in performance?
7  Bitcoin / Mining / 2G or 1G Radeon HD 5870. on: May 20, 2011, 05:24:54 PM
Is there any difference?
8  Bitcoin / Mining / Re: 4x Radeon HD 6990 on: May 19, 2011, 11:57:13 AM
A PCI-E slot provides up to 75W, each 8-pin connector up to 150W, amounting to 375W for a card. This is one of the reasons why GPUs of 6990 have to be underclocked (830MHz instead of 880MHz in 6970 and 6950) for stable performance.

Performance slightly decreases in standard tests (~10%), and while mining you need even less communication with the card. Consider this video:

And, please, post the software you are using.

Has anyone tried?
