epic.

what volts were running on the cpu ?

i'd jizz on a 5ghz run.

lol see what my HEC 500W did ... Golden PSU Components

Going any higher on memory for me (it's at 1100 right now) results in instability. I'll try pushing my core up to 950 and working from there (930 right now).

That's odd... With memory, I easily get up to 1150 without a volt mod or much change in temperatures.

I can't get the core above 930 without some extra voltage though.

EDIT: This is on the Diamond.

Sick, hit 970MHz. I thought my card had reached its max at 930, but that's because every time I tried raising the core, I also raised the memory. I guess my max memory is 1100Mhz. Now my core is at 970MHz, running F@H right now, stable, 67C temps @ 75% fan speed.

Hm, I thought the XOC was like an ultimate card, sort of like a black edition XFX. I have a vanilla 4890 and it's doing 970 stable stock voltages. Weird. Luck of the draw I guess.

So is everyone using riva tuner to increase the voltage? Im not all about flashing bios, but I know im close to being able to run 1ghz per core on my crossfire setup and I only need a small voltage increase.

[Afrodisiac]

Is getting 970Mhz on stock voltages lucky/golden, or is that normal?

[mxthunder]

My MSI card could hit 970 (880 stock factory clocked)on stock voltage with the fan at 100%
my xfx card could only do 955 up from an 875 factory clock.

Hey..

I got HD4890. It's very beautiful. But I got two problems with it:

1) On certain games you see artifacts, well.. I hope that's the correct world. But you see sharp things, messed up colors, "war of the black and white ants" (like on TV). I have no idea why.

2) It makes a lot of "electronic noise" during 3D rendering. Very annoying. It also does it when scrolling, moving mouse, opening documents etc.

Anyone else have these problems?

[mxthunder]

I assume you are not overclocked? What are your temps like. Try cranking up the fan speed manually and see if the artifacts go away.
The electronic noise is normal, annoying, but normal.
