Core 2 Duo and NV 680i Overclocking

Since I have a stable build I decided yesterday just to see what this 6600
could do with just default voltages on CPU and ram. Ram stayed set on
'Linked' and Auto and SLI disabled. I eased the FSB up from 1066 (default)
and finally up to 1333.3 for 3.0ghz easily. I was a bit confused with some
of the nomenclature of this bios as it doesn't seem to be the same as Phil's
on his 680i board. Mine has "FSB and Memory Settings" listed and the FSB
settings are listed as the actual ratings. I still may be doing this wrong,
but it does accomplish the OC. I ran Orthos for 16-18hrs overnight and all
seems well. I forget who reccomended it, but it sure will push the two cores
more than any other program I have seen. It actually pushed both cores up
into the 50c range which even video rendering could not get past 45c or so
after several hours. I didn't do any memory tweaking as I was just
interested in what I could get the CPU to for right now. To be perfectly
honest, I am a bit confused with all the memory settings except for the
timings and dividers. 5-4 and 3-2 will not boot to XP with the default
timings so I will have to do some experimenting there after I run awhile at
these settings just to be sure of good stability. I think that relaxing the
default timings might help a lot. Default is 3-3-3-4 IIRC so I have some
room to work with. The Overclocking section of the Asus P5N32-E SLI manual
is not very helpful when it comes to actually doing anything. The Asus forum
is not much better. Oh well, I will find what I need to know somewhere after
a bit of digging. That is where everything is now.

Ed, did you read up on this document yet? I downloaded it from a link
supplied in this newsgroup. I cannot find it anymore, but here's the link to
my FTP:

Thanks Thomas. It looks like a good read and will help. There is a lot more

there than in my Asus manual.

So here is my contribution, using nTune reports for the actual values.

_____

The solution (at least for my EVGA 680i motherboard) for reading the SPD
information is to use 'nVidia Control Panel' and select 'View System
Information' (this can also be done by starting 'nTune'.

THEN

Double-click on one of the processors in 'Processor information'; this
will
display the processor information.

THEN

Double-click on one of the DIMMs in 'Memory information'; this will
display
the SPD information, including any extended SPD information (SLI-ready
information.)

After double-clicking on one of the processors in 'Processor information'
in
'View System Information' clicking on the 'View SPD' button in 'Adjust
Motherboard Settings', then double-clicking on a DIMM in the 'Memory
Information' window WILL display the SPD information, including any
extended
SPD information (SLI-ready information.)

If I do not double-click on a processor in 'View System Information'
FIRST,
double-clicking on a DIMM in 'Memory information' does nothing AND
double-clicking on a DIMM in 'Adjust Motherboard Settings' in the 'Memory
Information' window [brought up by the 'View SPD information'] does
nothing.

Using the 'Create a tech support log file:' 'Save' button ALWAYS works and
creates a text log file that includes the SPD and extended SPD
information.

Thanks for the heads-up. The same works on my Asus P5N32-SLI also so you

have hit upon something that, at least, gives NView some use. Before, I
could not get any drop-down adjustment choices at all. I will do a bit of
tweaking there just to see if it can actually work.
