Topic: Asus Ares 5870 x2 Mining Details - ~440mhash/s - page 2. (Read 8859 times)

As seen in the original post:

OCED 975mhz, 300mhz mem:
Top Card- 80c, 98c
Lower Card- 83c, 94c

And yes, its already at Aggression 13, with no hang to my gui 

How are the temps at 975?  And if you move it to a dedicated rig (or when you're going to sleep/work), I'd recommend seeing aggression=12 or 13.  At least on my linux installs that squeezes out an extra 10-15 mHash/sec (although the GUI becomes unusable, luckily my machines are headless now).

We'll see how much we can pull out of em at those speeds

At 925Mhz, I'm seeing ~385 mhash/s

975Mhz - ~407 mhash/s

I'd definitely test what temperatures you can get at 975/300 clock speeds.  That's been the sweet spot for energy/watt ratio in my testing, and the underclocking memory that far seems to keep the temperatures comparable to stock speeds.

Hopefully you got a good deal on them.  It's been my experience (limited to 8 5870s so far) that brand means very little.  Current rigs have Sapphire (1), Gigabyte (3), MSI Lightning II (2), and an XFX (1).

All of them are currently OC'd to 975 core, 300 memory.  The GigaBytes, Sapphire, and XFX I undervolted to 0.950 volt (which is their stock voltage for idle), MSI Lightnings I kept at stock (they didn't like undervolting).

All of them at those settings run around 73-75C (in dual card systems), pulling 423-424 mHash/sec.  The exception is one GigaByte card which runs at 83C, but still stable at those same settings (and even at stock it always runs about 5-10C hotter).

At this point, I get whatever 5870 I can for under $220, because I've yet to get one out of those 4 brands that runs noticeably different from the other brands.

Just wanted to let the community know about my experience running two of these cards!

My mining rig:
1200w Antec PSU, very nice for this type of hardware.
AMD 1090T
MSI 870A Fuzion motherboard
Zalman GS1000 case

I've run a variety of GPU's in this case, and none of them perform as well as the Ares. When mining with a typical 5970 in quad-fire, I used to see temps at 80-90c for all four GPU's, and VRam temps usually at 120c. You could have literally cooked breakfast in my case! And this was at 100% fanspeeds!

In contrast at stock:
Single Ares mining temps: 60c-69c for both GPU and Vram!
Fan Speeds at around 45-60%

Dual Ares mining temps Stock:
Top card- 84c,89c GPU, 96 Vram
lower card- 69c,75c!
Fan speeds at around 45-60%
OCED 975mhz, 300mhz mem:
Top Card- 80c, 98c
Lower Card- 83c, 94c


Hashrates are about what you would expect for stock 5870's:
Standard Poclbm-gui:
318mhash/s per core. -v -w 128

Phoenix:

925MHz - ~385 mhahs/s AGGRESSION=13 WORKSIZE=128 VECTORS BFI_INT -k poclbm
975MHz - ~407 mhash/s AGGRESSION=13 WORKSIZE=128 VECTORS BFI_INT -k poclbm
