Apeart Posted January 12, 2010 Share Posted January 12, 2010 Hello, i've a little problem with my new system. My problem: If i activate the X.M.P. profile and push my cpu to more than 3,5 GHz (vcore on auto @ 1,36) my system freezes everytime i run prime95 (after about 3 - 5 Minutes). If the cpu runs under 3,5 GHz then prime is stable at 1,2xx vcore (still auto). What could be wrong ? I let all voltage settings on Auto except QIP (1,60) and RAM Bus (1,65). After searching in several postings my first thought was the PSU - but the Enermax calculator told me that even with overclocking to 4 GHz @ 1.35 VCore an 600 wats PSU should be enough. Another funny effekt I have with memtest86 - even all components at default speed - memtest crashes everytime at 7% and the system freeze (need to hard reset) regards and thx for your suggestions in advance Tobi Link to comment Share on other sites More sharing options...
Yellowbeard Posted January 12, 2010 Share Posted January 12, 2010 Can you run 3.5GHz with the memory at a lower speed? What is your BClock and uncore frequency? Also, on ASUS boards, you must disable Legacy USB Support to run Memtest. Link to comment Share on other sites More sharing options...
KILLER_K Posted February 11, 2010 Share Posted February 11, 2010 What prime setting are you using for the test? Have you tried your qpi on 1.55 and see what happens. As anything between 1.5 and 1.55 is fine if i go higher mine gets weird also. Yea and try lowering the memory speed down like yellowbeard suggested.
