Some of your voltages look excessive. There is no reason for IOH to ever be set above 1.1v except at extreme BCLKs (over 200MHz) or moderate OCs with SLI/crossfire setups. +200mv on QPI/Uncore is also likely more than necessary. I don't even use that much for 168x25, 4.2GHz core, 3.2GHz uncore, and 24GiB of memory. Unless your uncore clock is excessively high, or you are trying to run very fast memory, you probably don't need more than +100mv.
Also, in my experience, even multipliers are less stable than odd ones on both Bloomfield and Gulftown. I'd highly recommend using the 23 or 25 multiplier.


my bios will not let me adjust the multiplier at all...its locked out, anyone know a work around? I know the cooling isnt the best but they did have a factory overclocked option to 3.8Ghz with this SAME cooler so it is possible some how just not sure what combo of settings or if there is some other things going on there..... anyone with an alienware area 51 alx running around here?

What BIOS version are you using? Have you tried updating it?

Dell likely used considerably more conservative voltages, which would result in considerably less heat. They may also have done some binning of the CPUs as well.

My bios is version a10, I believe it is the latest version but i wil have to check later

Even with a H70, I could not handle overclocking on my w3680, so may need a different heatsink.

As far as the multiplier overclocking, you can't. You can only overclock by upping your b clock ratio (133 Mhz stock)

hmm all 970's have a locked multiplier? seems odd
post #26 of 26
You would need to buy either a w3680, 980x, or a 990x to have a unlocked multiplier. It is Intel's way of saying, pay more for more.

24x I think is the max multiplier on the 970. http://ark.intel.com/products/47933/Intel-Core-i7-970-Processor-(12M-Cache-3_20-GHz-4_80-GTs-Intel-QPI)
