It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on caller favorite stocks at rapid speed:

Acadia Pharmaceuticals: "I'm always forever hopeful. Because of what they have, I'm still saying it's a good speculation."

Micron Technology: "Right here, right now — I'm not longer putting the hate on Micron. Enough is enough! Micron is OK."

Gilead Sciences: "They have to do an acquisition. They have to do an acquisition and have to get some growth away from Hep C. Otherwise I can't go buy, buy, buy."

Compugen: "Genomics, there is only one company for genomics and that is Marc Casper's [CEO] Thermo Fisher with an all-time high today."

SunTrust Banks: "I do prefer Wells Fargo as my charitable owns. SunTrust is going to do great in this environment. But Wells Fargo, the bank of Buffett, I think can go much higher, which is why my charitable trust owns it."

Advanced Micro Devices: "I am no longer negative on AMD because they got a little flash action there. They got a graphic used interface. It's no Nvidia but it's too low. In a tech rally, I even endorse an AMD and a Micron."

Callon Petroleum: "It's got Permian assets, but that means if it's got Permian than I want to be in Pioneer. My favorite is Occidental, my charitable trust owns that because of the dividend."

Berkshire Hathaway, B class on Apple: "You'll never notice the difference. It's just too small to that position. IBM is more important and IBM's going higher now. I think that Berkshire is a buy, buy, buy."
