The electronic noise is normal, annoying, but normal.

Not overclocked. I will get up the fan speed next time, in fact I forgot to mention one time my game just shutdown. No errors or anything!

The noise, I don't know.. it's just TOO loud for me. Do you consider it that too? "too loud"?

Thanks for your response by the way.

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?

hmm as mentioned already i would say first things first, go into CCC, unlock the Overdrive screen and manually control that fan speed. i run mine @ 45% constantly, its pretty loud still but i can deal with it, and my temps dont go over 71c on the RAM chip @ 960/1030 during gaming.

according to Everest anyway

I just had a very scary experience:

I was messing with my RAM timings (as us OCers are wont to do) and I set my 1066 RAM at 800mhz 3-3-3-12 at 1.9 volts (lol the voltage was an accident and I'd heard that these timings worked with my RAM)

When I saved the BIOS, my computer powered on but would not POST. I opened up my computer and my brand new 4890 Toxic was doing the "3 blinking lights of death." I tried a lot of things to get it going again, including re-seating my RAM, the 4890 itself, booting with a RAGE 128 (best card of that era IMO) in the PCI slot to see if my mobo worked, etc, all to no avail...

It was then that I realized that I had forgotten to reset the CMOS, which was why I opened the case in the first place!

It was the top dog right after the 4890 came out. It was the highest clock out there when I got it. Just doesn't seem to clock the core very well. Once my Toxic shows up, I'm going to try to get them both to 1GHz Core and 1150 Memory.

wow thats... not far off the WR at all.

is it liquid helium time next ?

[gtarmanrob]

wow...i love this card currently 970/1100 stable with stock volts. and i broke 20k in 3DMark06

I'm having some trouble OCing my Sapphire VaporX 4890 . . . I can only get 935 core 1124 memory clocks without it going over 90 degrees C and artifacts in furmark. Any higher and my temps are creeping past 90 degrees and i start to artifact. I've seen a lot of people reach higher clocks with reference cards, and I bought this card with the hopes of hitting or at least getting close to 1000/1200. Thus far I'm pretty dissapointed. At least my games run on max though.

wow are u serious? is this even with the fans cranked to 100?tried a volt mod to maybe help u reach those clocks? i dont know if this will help but have u tried lowering ur mem clock and uping the core? sometimes it it works for me.

Tried it all except the voltmod. I haven't been able to find one or figure out how because I don't have a reference PCB so the voltmods I have tried won't work. However, I don't think they will work anyway because this thing is already getting too hot, and won't upping the voltage just make it hotter?

I've got a Cooler Master Storm Scout case with really good airflow and little dust (I've only had it for a month thus far). However, when I try to OC it I have the side cover off. I just ordered a CM 120mm fan to mount on the side of the case right next to the expansion slots to help move the hot air out from the GPU and PSU (even though the PSU fan is mounted rightside up on the bottom of the case and pushes air out from underneath, heat still rises and can linger in the expansion slots).

I've been working for the past three days to OC my CPU (issues with the Ram) and I've just been pretty dissapointed up until now with the luck I've been getting with the OC ability of my CPU and GPU.
