I7 920 IMC or VCore Voltage issue?

post #1 of 5
Thread Starter 
Hey there lads,


I have two I7 rigs : 920 C0 and 920 D0. I finally caught a break and returned home from uni. I haven't used my C0 rig for a few months. The usual turn on every now and then by my family and that is it. Yesterday, when I was flying back, my father turned the I7 C0 rig on and saw a message from my Gigabyte BIOS : "very high voltage something ... current h/w config does not match overclock'. The machine shut off and rebooted. It booted windows so my dad left it alone.

I landed, came home, wanted to use the machine (install Dragon Age 2) and the thing was barely moving. I checked the task manager, cpu usage 100 % and RAM 2GB out of 6 GB!! I did not even take a shower or change my clothes, opened up the rig ... took out the CPU and looked on the side ... I saw burn marks!

2 corners where the gold connectors are had a brownish colour. Used the Arctic Clean kit on it but it would not budge. I told myself this CPU got burned. So, disappointed I put the thing back together and didn't even bother setting up the fans on my VX plugged the RAM in, started the mobo with a screwdriver and just for the fun of it checked bios ... it was 6GB of RAM.


So I set up the rig, mount everything back and now I have 6GB of RAM working properly. I did not overclock it yet but it seems that overclocking within the INTEL Voltage tolerance on both the IMC and Voltage caused burn marks on my CPU . This is not normal ... could my X58 Gigabyte UD3R have a problem with Voltages??? I will never buy Gigabyte again ... I've only issues with the UD3R .

Burn marks? That's crazy! What were the vcore and vcc volts. Also what TIM and which cooler?

What clock speed were you running it at? I'm sure temps were nice and low with that cooler. This is relevant to my interests, in a bad way. "Safe" voltages, 920 c0 and a UD3R.....

Between 3.6 GHz and 3.8 GHz.
