From what I'm reading, overclocking will not offer as much headroom due to overspeed protection, but is still possible. Questions about taking a 920 to 3.2 or so. Forum police, please bear with me, a couple questions are on memory. I didn't want to double post:
Here's what Tom's says about overclocking:
"It is entirely possible that a given Core i7 940 or 920 may actually only consume 70, 90 or perhaps 110 watts. If you are lucky enough to find yourself with a 70 watt version, that gives you an overhead of about 50+ watts for overclocking, and you?ll be able to increase the core voltage enough to see some good results. Conversely, if you end up taking a 110 watt model home, you?ll only have 20 watts of overclocking headroom before the CPU begins to throttle its clock speed. In this case, the same model of a CPU will offer much lower overclocking potential due to the Overspeed Protection feature." Source
Bjorn makes it sound easy though:
"The Core I7 920 overclocked nicely from 2.66GHz to 3.433GHz with little to no effort. Will the Core I7 920 clock higher? You bet it will, we've seen it as high as 4 GHz pushing 1.45 Vcore, is it safe to run it like that? It's probably not safe to run the Core I7 920 at 1.45 Vcore, 45nm CPU's aren't known to be very tolerant to over volting. If you want to push it that high your going to need more than air cooling which is what we had available. The 3.433GHz was achieved with the Thermalright Ultra 120 RT which handled the Core I7 CPU's quite nicely up to 3.86GHz on the 965, and 3.43GHz on the I7 920. Stock cooler that comes with the I7 920, well your probably good up to 2.8GHz so make sure and budget for some good cooling." Source
Comments on overclocking? Upping a 920 to 3.2 is possible right?
Overclocking Project
1. Taking an i7 920 to 3.20, DDR3-1280 is sufficient? i7 memory profile
2. What speed and voltage memory should be selected per this comment... "We also received 6 GB kits from Corsair and OCZ supporting 1,333 and 1,600 MHz frequencies at Intel?s recommended 1.65V ceiling." last sentence on page
3. Planning to run three sticks. Choosing between these in the 1.5-1.7v range?? DDR3 2GB
4. Love Thermalright build quality. How's this bad boy looking?
