790FX + RAMs at 1.65v ok?

No one?

your motherboards default voltage should be 1.8v for the ram. its the intel i5/i7 thats rated for 1.5-1.65v. i wouldnt change the voltage from where its currently at if its stable

likely, your clicking sound is coming from your power supply being under a higher load with the 5850 installed. power draw from a 5850 is higher under load than a 48xx card. also, ive noticed some older corsair units had an issue with clicking under load (requiring an RMA to fix the issue)

what PSU are you using to power that rig?

side note - bump your ram voltage up to 1.8v anyway. i really dont think it has anything to do with the clicking..but that MIGHT help with the black screens..however, the black screen is likely caused by a power shortage from your PSU.

test your ram at its current voltage with memtest 86+. its free and easy to use. let it run for an hour or two, and if it comes up with no errors at current 1.65v then id leave it alone and blame the PSU. if it detects ram errors..bump voltage up to 1.8 and re-run the test for another couple hours. if errors persist..it may be time to consider a new PSU for that nice rig you have

I have this

Wattage: 850-Watt
Ultra X3 850-Watt ATX
Input Voltage: 115 ~ 230
+3.3V: 24 A
+5V: 28 A
+12V 1: 55 A
-12V: 0.8 A
+5VSB: 3 A

I'll come back after memtest

I used memtest86+ 4.0 and 5 passes and no errors

***** End of report *****

you could try RMAing that psu and see what the results are..but i never cared for that brand. if your budget allows..a nice 650w corsair/antec would do quite nicely. its not your ram, leave it at 1.65v. with the 5850 installed try and run whatever program caused the ticking noise and put your ear up to the psu. my moneys on that as the culprit of the noise and crashes

Thanks, I will remove it from my PC and try to see where the noise is coming from. No idea why I didn't think of that
