Right.. The infamous GiGabyte K8 N SLI Pro MoBo. How frustrating this is .. I found the perfect combination of Ram timings and settings for this chip to get a really nice stable overclock yet the bios is a bummer! HTT @ 4x I have 2 gig of DDR 400 ram in Dual Mode @ 3337 CPU set to 250 Multiplyer set to 10x Ram multiplyer set to 2/1.66 Now with this set up this should get a really superb group of settings with the HTT running @ 1000 (x2) 2000Mhz Ram = 415Mhz Cpu = 2.5GiG I adjusted the Voltage of the cpu to 45 The ram I set to +.2 The HTT was left at current voltage as with these timings it is running as normal at the normal frequency.. Yet the bios will not allow what seems here to be a perfectly balanced overclock The only way that the settings will post is when I set the HTT to 3xtimings but that reduces the HTT fequency to 750 Now although the computer runs well at these settings after a while playing a video game it will hang and get stuck in a sound loop. I have tried downloading older Bios but It makes no difference and despite all of the settings in the bios being on manual settings it will not allow me to post a 4x multiplyer for the HTT link. Is there anyone out there that knows how I can get this to set at 250 cpu clock with the settings that I have listed?
