E6700 over clocking

I'm currently playing about with overclocking my E6700 to 3.2ghz, but there seems to be some weird reporting between Core Temp, Orthos and CPU-Z.

Current setup is:

E6700 Rev B2
Gigabyte X38-DS5 (F5 bios)
4gb of Geil ULL 6400
Enermax Server PSU 670w
Freezer Pro 7 Cooler
AS5 thermal paste
Orthos running for 2hrs gives temps of 65-67c (Small FFTs)

In the bios i've;
* disabled all the normal power saving features
* disabled turbo mode
* set the cpu voltage to 1.35
* set the memory to +0.3v taking it to 2.1v
* mulitplier is @ 8
* FSB is @ 400
* timings set to 5-5-5-18
* divider is set to 2.0A which is 1:1 according to cpu-z

If i try 285+ * 10 the system just loops and finally resets to defaults.

Anyhow in cpu-z core speed, mulitplier, bus speed and rated fsb are showing what i would expect however the core voltage flicks to and fro 1.296v -1.312v. In coretemp the voltage reads 1.3250v but it thinks the frequency is 4000.20MHz (500.03 x 8.0). Orthos thinks the cpu speed is 4000MHz too.

Any ideas on why there are differences in what is being reported?

Also any tips on improving the overclocking would be most welcome

Thanks

never used them programs soo cant help you there but i do have a e6700 running at 3.3 all that was needed for that was just to put fsb to 330 from 267. all voltages at stock every at at stock and voila 3.3 with 10 seconds work

i kepy my mem timings at 4-4-4-12

i dint try going any further just stuck that in staight away on afresh install.

Hmm, interesting. My mate who has a abit P35 pro & same cpu just changed his fsb to 300 and left the multi at 10 and worked fine. I'll have to have a long play.

Thanks!

yeah its worth just trying the fsb and nothing else.. if it fails take a look at the memory casue changing the fsb effects the speed of *** ram also soo could be *** ram causing to fail. also worth checking what vaults your ram getting and what the manufacturer recomends as sometimes the default board voltage for the ram is slightly lower then manufactureres reccomended
