i7 920 bios settings

[strep3241]

I have been recently having trouble with my machine randomly freezing on me. I been thinking it is the cpu related because I had it overclocked to 4.2ghz for a while, I recently turned it back to stock settings and that is when the freezing started. It also occasionally stutters when playing music.

According to Intel, the memory I have is not compatible with the cpu. But the bios shows it running at 1066mhz and 1.5 volts which is recommended.

I took some pics of the bios settings and I want you to look at them and maybe there is a setting that is wrong.

could have sworn i saw this post yesterday, and i replied to it? but maybe it was deleted

I would check with the manufacturer... as to what the recommended voltage is for those sticks, and at what settings... I thought they were rated for 1.65v and 1600 rather than the 1.5v and 1066 your showing? It may be fine to downgrade the speed , but they may not run stable at that lower voltage...

the rule of thumb, I recall, with the processor you have , is that 1.65v is the limit.. not 1.5v.. However, you need to ensure that difference in voltage between the QPI/VTT setting and the ram voltage is 0.5 v or less.. so you don't fry the chip...

... but please doublecheck my comments.. i'm quoting from memory... so not 100% sure...

In any case, with corsair ram, you sometimes have to go in overide the settings, and not let them default to AUTO in the bios.. so look at the stick and set the voltage and latency settings manually to what the sticker states.. and then make sure the QPi/VTT setting is within the stated allowable difference... (which i think is 0.5v)

I have a similar thread in the computer help section which you replied to so that is what you are thinking of.

Yes it is rated for 1.65 and 1600. The bios automatically changed it to 1.5 and 1066. Maybe it did this because that is what is supported by the cpu.

If the cpu does not support 1.65 and 1600, why would it run stable at those settings?

yeah the downgrade from 1600 to 1066 makes sense to match up with the CPU capbabilities.. there's never a stability issue with slowing down your ram...
But lowering the voltage can be another story... My point is that if the modules you use are rated for 1.65, but your rig is down volting them to 1.5v, that can be causing the issues you're seeing....

Once again.. you need to contact Corsair.. with this question. It's there RAM.. and they'll know right away... (www.theramguy.com is their forum site.. i think)
