I have this too. It's called coil whine and I only get it when overclocked to the gills and running a game or benchmark. Not sure it's "normal" but it happens.

Correct. You only disable ULPS if you use AB or Trixx and crossfire. Single cards don't use ULPS.

If you dont disable it will you be guaranteed to crash ? I just ran a quick 1000mhz OC and yeah, no crash even when the second card went to "sleep".

I'm now doing a new leak test of my rig with the new mounting of the block with the corrected placement of the thermal pads.

Really sketchy mounting as well, scooping up TIM off the core, cleaned the surfaces and best effort to form a new TIM pea. I hope it will work as good as it potentially could before, as no heat has affected the TIM at least redface.gif

Well, we will see how this goes. I have to order new TIM because I ran out yesterday.

Some spills also.. But I have had worse scenarios spills than these ones.

So I have to see if it works tomorrow mellowsmiley.gif

Is it something to be worried about/alarmed ? RMA worthy reason ? And yes it only happens like you described.

I had the same thing with my 5870, in my case it eventually stopped after a while (at load).

No. Every Amd card I have owned for the last 4 years has had coil whine while over-volted and pushed to the limits. It's annoying, but not card threatening.

Some coil whine is inevitable especially on high end cards that draw tons of wattage. If the whine is excessive you can RMA, but then RMA sucks and you will be w/o card for a while I suspect since stock is low. Also on new cards, they don't typically have replacements in the RMA dept yet... this happened with Cayman too. No replacements for weeks.

I just installed my 2600k today. Yes, I literally went ahead and bought a 2600k after I saw that screenshot, and from people who has 2600k, like Demin who helped. I had $1200 in GPUs but my 2500k was holding it back in BF3 since my GPU usages were floating around 75-90%, never utilizing its full potential.
Anyways, installed my 2600k today, OC'd it to 4.5ghz just to test it out at 2500k speeds. In the same Strike at Karkand map, where my 2500k would struggle it seems since both my GPUs would fluctuate between 75-90%, the 2600k with HT on pegs my GPUs at 98-99% 99% of the time, just like the AB screenshot Outcast posted. I am happy now. I didn't even try to push my 2600k further. Granted, even with the 2500k and my GPUs at 75-90%, I was still able to get 60+fps most of the time, but I'm willing to spend $100 to ease my mind knowing that my CPU isn't severely bottlenecking my $1200 video cards.
Thank you Outcast for spending my money, now I just need to sell my 2500k.

I'm a little confused. Hyper threading does not effect game play. Other than the extra GPU processing I can't imagine how it made much difference?

My i7 950 (4 Core) HT runs on par with a FX 8150. It's just a sliver behind a i5 2500K.

The 2500K bottle necking you crossfire seems weird, when it dosent bottle neck the i7 950.
