CPU voltage spiking using DDR3 2000 Mhz

Hello,

I'm new here and could use some help with my new system. In short, On the Gigabyte UD5 board I had to enable Extreme Memory Profile (X.M.P.) (switched to Profile 1) in order to boot using DDR3 2000 (PC3 16000) Memory. this has caused the CPU voltage and Northbridge voltage to spike. Is there a setting in the bios i am missing in order to not run the CPU so hot and also have the memory timing at 9-9-9-24, 1.65v?

Any advice to get me through the weekend until I can call Gigabyte on Monday would be very helpful and appreciated.

Intel Core i7 920 Nehalem 2.66GHz LGA 1366 130W Quad-Core Processor Model BX80601920
GIGABYTE GA-EX58-UD5 LGA 1366 Intel X58 ATX Intel Motherboard
G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) Model F3-16000CL9T-6GBPS
GSKILL 2.5" 64GB SATA II SSD
Microsoft Windows XP Pro 64-bit
Zalman ZM750-HP 750 Watt


Thanks!
 
First, the CPU voltage meter on the board is in the red. Second, the bios settings. (which i don't fully understand yet)

QPI Link Speed 5.14Ghz
Uncore Freq. 4004Mhz
BCLK Freq - 143
CPU Vcore - 1.28125v
QPI/Vtt voltage - 1.15
IOH Core - 1.100v
DRam Volt - 1.5
CPU PLL - 1.800v

does this help?
 
Oh, I thought you mean a voltage spike. You can try lowering vcore to ~1.2V, that should cool down your CPU a little.
 
Sorry for the confusion. Not familiar with all the tech terms yet. I lower the vcore to 1.2v but the CPU voltage meter on the motherboard is still in Level 3 (red). Do you think i purchased memory that was too fast for this processor?

No you're overclocking it so that should be red. Just lower that vcore down to 1.2v and it'll bring the core temps down too.
 
i see. we'll the problem the overclocking is causing is a fast cpu fan speed (noisey even for Zalman) and a high pitch continuous beeping. Which is very annoying. I don't know if that's caused from the overclocking or what. Arrgg. I really don't want to overclock my cpu. Can you recommend triple channel memory that will not overclock the 920 i7?

thanks
