Is my CPU fried?

I have an Intel Q6600 that I've had for a while now. Originally it ran overclocked to 3.6 without issue but I had to use 1.6V to make it stable. It's always been on water cooling so the temps were not an issue. At one point I started noticing artifacts in images I was editing in Photoshop. I lowered it to stock settings and the artifacts disappeared. They were not video card related, I checked. I then sold the motherboard I had an upgraded to an Asus Striker Extreme. What a POS board that was. Nothing worked right on it. I couldn't keep it stable to safe my life even at stock settings. I finally got fed up with that after 2 months of pain and sent it in for a full refund. ClubIT was very nice to let me do this after the 30 days ran out. Now I have a brand new DFI UT P35 board and its still still randomly locking up and bsod'ing on me. All at stock settings. My question is, did I kill my CPU running it at 1.6V for so long? It was probably at that voltage for 4 months before it started acting flaky. I'm going to get a new Q6600 G0 stepping but I wanted your opinions on this so I don't do it again! Thanks Guys
 
sounds like a memory prob to me. have you run memtest at all thru this ordeal? bsod is usually a memory related problem.
 
CPU problems dont cause graphical artifacts that ive ever heard of. CPU problems cause blue screens and crashes.
 
Yes on the memtest, I have 2 sets of ram. 4 1gb sticks of G.Skill which work no problem, and 4 2gb sticks of G.Skill that also pass with flying colors. Memtest was the first thing I tried when I kept getting bsod's. The graphical anomalies I'm talking about were simply little solid color dots that would pop up whenever I opened an image from a raw file in photoshop. The more I edited the picture, the more dots would show up. They were exactly one pixel each. However some of them looked like they were AA'd like in video games so they looked smoother. Some were just bright hard dots. Red mostly, some green and a few blue. Solid colors of each, not variations and always the same brightness. If I reopened the same image at stock speed, no dots. If I saved it when over clocked the dots got saved with it. At first I thought my camera was shitting the bed but its brand new. I knew they were not from the video card either, games and stuff still worked. I had stress tested my CPU at 3.6 1.6V using 4 copies of Prime95 and it would hit 70C even with water cooling. The sucker ran HOT. I don't know how accurate that temp is though because the 2 newer boards show temps way cooler. I cannot over clock it at all now, it fails almost instantly. This is why I think I fried it. Hmmkay?
 
Yeah you may have fried it. I've had OC'd processors, where I'd have to back down closer to stock to run stable again. Have you tried running Prime underclocking? Also, have you tried doing what you do underclocked? Try to isolate your components. Run 1 stick of Ram you know for sure is good in the meantime, to eliminate a faulty Ram Module, Ram Socket or Mobo.

Do some stability testing underclocked and with 1 stick of memory and then start clocking higher till you fine errors again. If you're getting BSODs, what kind are they?
 
Unfortunately, the only way to isolate things is to run the CPU and MOBO separately. Since you already have replaced the MOBO, and have tested all the ram, all that is really left is the CPU. :eek:

Maybe the high voltage you were running grew a Tin Whisker.
