1333MHz FSB processor damaged if put in 1066MHz mobo?

[dean]

Can anyone tell me if I have damaged anything here: I plugged an Intel
E6850 3GHz Core2 duo into a D975XBX2 mother board. Would not even
system beep or bring up bios or post. I now realize these are
incompatible, as the processor is 1333MHz FSB and the board is max
1066MHz. I'm planning to return the board and buy an ASUS board that
supports this processor. Not sure if I have damaged anything though.

Thanks for any help,

Dean

The 'Bad Axe II' does not support 1333MHz processors. Chances are good no
damage was done.

If overclocking is on the menu consider the E2160, E4300 or E4400.

Agreed.

I'd forget the E2160 as it has small, individaully accessed L2 cache which
makes a huge difference to performance. I'd go for the E4500 (2.2GHz) and
boot it at 1066 at default vcore for 2.93GHz. That's what this machine is
running. (And it doesn't even have any overclocking options in the BIOS, I
had to do a BSEL 'pin' mod, took all of 15 minutes, mostly waiting for the
paint to dry.)

Quite true when you mention the additional L2 cache of the E4xxx series. The
primary reasons I mentioned the E2160 is the price point ($83US vs $130US
for the E4300/E4400/E4500) combined with the probability of overclocking it.
A 50% OC at stock voltage without the need of hardware mods seems pretty
good to me.

My primary concern is stability. If I can overclock by only 20% and have it
rock solid then I'm satisfied.

Nice 33% gain from the BSEL 'pin' mod. Just one reason to try the newest
version of Prime95.

Ok thanks, good to know. I did order a new motherboard: ASUS MAXIMUS
FORMULA / SE. The reviews suggest its good, and (never done this
before) simple to OC.

One thing I can't figure out (please excuse my newbie question) is:
are those copper pipes going to the bridges filled with liquid (heat
pipes) or are they supposed to be used with water cooling or
something. I was planning to use the intel cooling fan on the E6850 as
is for the time being.

Water cooling can be used but it's not connected to the existing heat pipes
of the motherboard. Both are closed loops.

Stock air cooling is fine if you don't greatly increase Vcore(CPU voltage).

If anyting the processor might be damaged, but highly unlikly.
Basically you overclocked it, the board should be OK

That would have underclocked the CPU not overclocked and
would not harm it.

You should be fine for now. The board you've ordered has the facility to
water-cool the northbridge, and, via the heatpipe links, the southbridge and
VRMs as well. However, it can be used without water-cooling. Be aware, I did
read a review that said that the integrated water block on top of the
northbridge heatpipe can trap heat and cause the northbridge to heat up
excessively when water cooling isn't used and you're really pushing the OC.
It was for that reason that I just yesterday advised a friend against the
board as he has no intention of ever water cooling.

However, that said, he also isn't *that* ambitious an OC'er either. I'm
building and OC'ing his (Q6600) system for him. I'll push it, find it's
limits, then back it off a bunch so that it's safe.

Cheers,

Ok thanks for that. Not sure what is possible with water cooling, in
terms of GHz, from a stock 3.0GHz E6850. But before I plug this onto
the board and turn it on stock, do I need to set anything, such as
voltages or bios settings? (Sorry its been 10 years since I built a
computer).

No, just seat the CPU into the socket, insert the RAM and graphics card and
fire it up. You may need to update the BIOS, there are new CPUs coming out
so fast that I'm finding that most boards need a BIOS update out-of-the-box
to support current CPUs.

Luck,
