I do not now what these temps are?
__________________________________________________ ____________________

200 BCLK x 23 = 4.6 GHz Over Clock

My highest CPU temp after running for 1 hour 75c to 78c Real Temp

Ran Linx 1 Hour no errors, Ran Intel Burn Test 1 Hour No Errors

Ram mem Test 1 Hour no Errors

Why do I get these warnings?

The following warnings POP Up

Dram Busv 4.32v
IOHV 4.165v
QPI Dramv 4.165

__________________________________________________ ____________________

I feel like this is a very low score for 4.6 GHz
3D Mark 11 Score X4154

CPU 3.6GHz Stock settings
3D Mark 11 Score X4117

Need advice On Over Clock or are these good settings for 24/7 use

I think my dram Freq are incorrect with the BCLK and N/Bridge ?

Yes, you may want to adjust the memory ratio/divider up to 8. 10 would probably be pushing it at that bclk.

those look like these are being misread - this can happen if you have multiple pieces of software open that probe the onboard IO chip simultaneously. As for the warnings themselves they are just an alert to notify the user that some of the voltages are running beyond specification.

As Xeromist said you can set the DRAM multiplier ratio to 8x to get DDR3-1600 speed effective at that BCLK - should fit in nicely for your DRAM.

I suggest updating the BIOS, I have seen similar voltage read outs on boards in the past and a BIOS update solved my issues :)

Give a bump to your ram speed and set it at 1600MHz
