This week I got a 3770K 3230B665 E4 off eBay and have tried to get it stable at 4.6GHz. I started with a voltage offset of +.010 and IBT would crash, so kept upping the voltage. As of now, it's at +.050 which show 1.318v in CPUZ and temps using my NH-D14 are in 86c with IBT being stable.
So I guess this is a crappy OC chip I got then? Any recommendations?
So it's been about two weeks now.
I've had success at 4.5GHz, but I'm still having a hard time finding a stable 4.6 OC.
Here are the settings that I've been using for 4.5GHz for a few days, stable with Prime95 24hr and IBT at 12hr.
Voltage offset +.005v, Turbo voltage +.008v, LLC 5, CPU PLL 1.750v (lowered from Auto 1.832v), VCC VTT 1.05v Auto, PCH 1.059v Auto, VCCSA 0.925v Auto), DRAM 1.650v 16GB @ 2200MHz.
With those settings, IBT shows 1.248-1.256v with temp of 79c, and Prime shows 1.240-1.248v with temp of 79c. Idle is 1.136-1.160v.
I first tried LLC at 2, then went down to 3, 4, and ended up with it at 5 (the lowest) as any higher was causing too much voltage and the system to be unstable and kept failing Prime and IBT after 30-90min.
I did try to increase the VCC-VTT and VCCSA as you suggested, but it didn't do help with a 4.6 OC, as that keeps failing.
I've increased the Turbo from +.008 up to +.043 in steps, and still 4.6GHz fails.
This makes no sense to me. I've been using these above settings for 4.5GHz for a few days. Everything has passed, IBT and Prime 95. Today when I turn my system on I start up Prime and it fails after 2-5 min. Same thing with IBT. I lower it down to 4.4 and and get a BSOD while windows loads. Upped the voltage, now windows loads but prime still fails.
I don't get how I can get 4.5GHz and it is working fine about 4 day, even 24hr of Prime passed and a few hours of IBT, but today both keep failing withing a few minutes of starting the stress test.
