Gigabyte EX58-UD5/Extreme Discussion Thread

[PeterW_R]

Hi guys,

This board can reach 211 BCLK with 19x multiplier, but my CPU seems to suck when overclocking (I have a C0 stepping 3841A700 batch)

I'm now stuck at BCLK 196 with 21x multiplier, any ideas about how can I get this to magic number 200?


Temps are not a problem as I have phase change cooling in my CPU (Inner Cores report an absolute max of +15ºC, minimum of -22ºC, averaging -7ºC, compressor is at -32ºC at load).

Current X58-Extreme Bios settings:
