I7 920 2.67 Ghz and ASUS PT6 Deluxe advice

[veneratio]

Hi, I have an ASUS PT6 DELUXE motherboard with the following system components:

■CPU: Intel(R) Core(TM)2 i7-920 2.66 GHz 8M L3 Cache LGA1366
■FAN: Asetek Liquid CPU Cooling System (Extreme Cooling Performance + Extreme Silent at 20dBA)
■HDD: Extreme Performance (RAID-0) with 2 Identical Hard Drives (1TB (500GBx2) SATA-II 3.0Gb/s 16MB Cache 7200RPM HDD
■MOTHERBOARD: Asus P6T Deluxe Intel X58 Chipset SLI/CrossFireX Mainboard SAS Triple-Channel DDR3/1600 SATA RAID w/ eSATA,Dual GbLAN,USB2.0,IEEE1394a,&7.1Audio
■MEMORY: 6GB (3x2GB) PC1333 DDR3 PC3 10666 Triple Channel Memory (Corsair or Major Brand)
■POWERSUPPLY: 680 Watts Power Supplies (Hush Power Supply SLI/CrossFire Ready)
■SOUND: HIGH DEFINITION ON-BOARD 7.1 AUDIO
■VIDEO: NVIDIA GeForce GTX280 1GB 16X PCI Express] (EVGA Powered by NVIDIA )

Prior to overclocking, my temps are as follows with little load (firefox, antivirus, some basic start up programs running)

Than, after overclocking the processor to 3.8 Ghz I get these readings with little load

The computer seems stable, however I am not sure if the core temp's are too high while overclocked with little load? I don't want to destroy the CPU when I play games because of over temp. Any suggestions? Thanks.

Hey veneratio, thanks for sharing the details! I would worry about your core temps (based on the assumption that anything approaching and surpassing 70C is bad). Have you considered installing third-party cooling solutions, like a bigger HSF assembly or even a watercooling system? Those are usually required when you're approaching 4.0GHz on the 920.

Isn't the max dram voltage suppose to be 1.66, but you're at 1.71. I'd be more worried about that. Personally, you're temps are fine, but I don't know what you oced the cpu to. I'd recommend doing the actual max oc, then see if your temps are weird.

Urgent!!!

Intel notes that max DRam V must be below 1.64V or else you are risking to fry your CPU for good

Take it down to 1.64V immediatly

The most important thing about the DRAM voltage is to keep it within .5 volt potential difference with Uncore/QPI voltage. Maximum recommended QPI voltage is 1.35 V, so DRAM is safe up to 1.85 volts. The 1.65 volt limitation applies to a stock QPI voltage of 1.2 (with a small factor of safety). So if you raise your QPI to 1.3, your DRAM is OK at even 1.8.
