probably closeness helps with optimal traces etc = higher mem clocks ???

supershanks

yes maybe , but not noticeably
If I was one for conspracy theories, probably the water cooling lobby slipping the board designers something to make pps switch from air cooling to give space for their high cooling finned ram & ram coolers

The only board from either Gigabyte or Asus with P55 chipset that would have enough side room for CPU coolers and 120mm fans without going top to bottom orientation of the cpu cooler is the UD6 boards from Gigabyte with its 6 dimm slots, so far anyway.

I can finally get the other 120mm fan fitted on to my Noctua HS while still running dual channel ram. This means I have 2 x 120mm fans fitted but can only do this with 1002 bios. Before i had to have 3 dimms to run dual channel. Now I have about a millimeter to spare between the ram and fan. Overclocking past 200BLCK is easier too.

Good to hear man, 2x 120mm fans - how much of improvement in temps/ocs ?

Tekxpert

Very minimal as the fans are running @ stock speeds eg. 1300rpm, I'm still using my old Cooler Master Stacker case too. I've only played with the Vcore and Vdimm, everything else is on auto. HT is enabled
This is what I'm getting to be stable 10 runs IntelBurnTest:

Whats the maximum 'safe' IMC voltage these socket 1156 cpus can take? thanks

eva2000

84C Load temps!! Still good as doubt 24/7 regular apps put as much load on the system as burn in test.

Vaguely recall intel spec docs

1366
- max cpu = 1.35v although according to docs max vid range can be up to 1.375v http://ark.intel.com/ProductCollecti...familyID=28037
- max cpu vtt = 1.35v

1156
- max cpu = 1.40v
- max cpu vtt = 1.25v
