AIBooster & CPU-Z show voltage as 1.26 under 100% load and 1.28V idle. I set it to 1.3125V in BIOS.
FSB:DRAM-1:1,Speed-3333=370x9. Mushkin HP2 RAM 4-5-4-11@2.1V.
Bios 1707.
In BIOS, SpeedStep-disabled, virtualization-enabled, hyperpath3-disabled, enhanced memory map-enabled, dram throttling-disabled, C1control-disabled, microcode update-enabled.
Vmch - 1.55V

My orthos blend test fails 15mins when temps reach 62C on 100% load. Do I have to hike the Vcore? It seems silly at this bus speed. It was fine at 368 and 1.3V.

BIOS tells me that by enabling cpu ratio setting, the EIST will be automatically disabled. I noticed that Everest Ultimate reports in its CPUID that EIST has been enabled. I am surprised. Is this the reason? :confused:

Is there anything else I need to do?

I would not consider more juice untill you get the temps down, What do you use for cooling?

Wood, you're right. I put on an AC Freezer 7 and temps dropped amazingly. above 90% load & at 37C. :)

Took a while to figure out, but the freeze disappeared once I set the PCI-E to 100 & PCI to 33. In fact now, I am down to 1.3VCore & rocking 24/7 at 3.33GHz. :D I will save this profile for summer & see if I can go higher to 3500 (390x9) for now.

Good for you dude! Your temps are great. Always watch your temps, wouldn't drive your car w/o water, would you?
I set the PCI-E to 100 & PCI to 33.
I have my PCI-e set to 120 which is high, I believe yours shoud be up around 115. Don't thake my word as I'm not positive. Google... that board should get 3.4 wth ease. I've read of many higher and I'm thinking that mushkin can handle the speeds easily.

Or engine oil :)

I'm now at 3.42 & temps have risen to 42C on load. I think its the voltage, 1.325V. Unfortunately, there is no stability even after giving this juice. The voltage drop is bad & it runs at 1.27V on full load.

There is no stability with Orthos, but Dual instances of Prime95 run fine for 30 mins. Temps really soar to 50C and I stop it at that.

trOver - I am glad. Try going up to 380 FSB.
