I'm currently using an Asus P5B Plus with an older Conroe running at 2.13
GHz. 4 Gig DDR2-800 memory.
The P5B uses the Intel P965 chipset and claims to support 1066/800/533
system bus speeds.
I now see all sorts of Core 2 Duo and Quad offerings, but I'm pretty sure my
older motherboard poses some limitations.

Which of the newer CPU's will work in the P5B and which are to be avoided?

Have finally got round to investigating the problem.

Repalced ram with Crucial DDR2 667. It will now POST to 256 MHz with
PCIE Aysnc at 114MHz. NB There is a PCI bus lock so that keeps it at
33.3MHz anyway.

DRAM timings are from SPD (makes no diff if not). These are at 255.8
MHz and a 1:1 ratio:

3,3,3,9,12

What I think is killing the overclock potential is the Vcore - I can
only use Auto or High usefully (haven't tried Low). Thishas resulted
in a Vcore pretty much the same as stock at 200MHz; 1.2v

Any suggestions to unlock the potental of the E4400?

I was tinkering around my BIOS after listening to a podcast about
overclocking and I found where I could Change the FSB of my CPU. It
was running at 2.8 ghz and the FSB Was 133. I slowly crept the FSB to
144 with multiplier at 21 as any higher gave me errors in windows .
My 2.8 ghz is now running at 3 ghz. Awesome.
But whats really amazing is my favorite online game BF2 No longer
Defaults to medium settings on everything but on High Settings. My
frame rates shot up to 10-15 extra frames per sec too.
My Question is then: How can A mere 200 Mhtz increase make such a big
difference????
My System Specs: Windows XP, 2 Gigs Ram, Sapphire HD3850 with 512 MB

I implemented AHCI on a Vista Ultimate system with three SATA drives
(changed the registry to load the MSAHCI service). I think I ended up with
two arrays - one containing all the partitions on the boot drive and a
second array for the other two drives. I used Vista to recreate the
partitions on the second array and everything seemed to function normally -
except the Intel Matrix Storage Console 8.5 said that NCQ was not
implemented on the non-boot drives. I can go back and forth between IDE and
AHCI and Vista does not have a problem with the partitions on the boot drive
but the other two drives are a problem. I have given up on AHCI unless
someone can point me to some good technical information on how it works. I
have another system with the almost exact same configuration running...

If that is the only thing you have changed then you have your answer.

If you had "value" ram before and it would not O/C, that s why, its
"value" ram for a reason.

Higher priced and higher quality ram will generally always be faster
than similar cheap ram.

configurations...? try to find your answer on...

Does any one know the identity or number of the motherboard in an Acer
Aspire M1640? Or better yet, a link to the manual for the motherboard?
The M1640 comes with hard/software support for RAID (NVIDIA). Hard
drives are really cheap so I was considering installing RAID 0 support
with two drives. Do they need to be identical? When my M1640 boots a
BIOS message "single channel mode" flashes. Presumably the board knows
about dual memory channel mode. How do I implement dual channel mode?
My M1640 comes with a Intel Pentium Dual Core E2160 CPU clocked at 1.8
GHz. Before I purchased the PC, I read a review stating that this CPU
(a $79 chip) could be overclocked at up to 3.2 GHz. Now that I have
the unit I see that there is hardware and software support for
variable clock rate. I enabled this feature through Vista. Now when
idle, the clock runs at 66%% or 1.2 GHz. If this unit could be
overclocked to 3.2 GHz, I think the variable clock technology would
scale it back to 1.2 Ghz when idle and gas it up to 3.2 GHz if/when
needed. This would save on power, heat generation and make the system
stable at overclocked speed. The system comes with a variable speed
CPU fan and the BIOS reports the CPU temperature and fan speed. When I
looked, the CPU temperature was reported to be 30 C. The BIOS had
features to enable warning and shutdown when the CPU temperature ...

been looking at Gigabyte GA-EP45C-DS3R and Asus P5QC...

Thoughts?

I mentioned here a while back that I was going to upgrade my E4500
[65nm/2.40GHz/2MB] @ 3.32GHz/1.375V for an E7300 [45nm/2.66GHz/3MB] and that
I was hoping to get 4GHz out of it.

Sadly I was aiming a bit high. After much non-POSTing, not loading Windows,
BSODs and Prime fails I found that it topped out at 3.6GHz but that it
needed 1.400V set in BIOS [CPU-Z reading 1.380V] to be Prime-stable at that
speed. I ran it like that for a week or so but decided that I'd see what I
could get with a lower vcore. I can't afford to fry a CPU and these new
hafnium gate processors are supposed to be sensitive to vcore around 1.4V
and higher over a relatively short time.

Long story short, I'm running at 333 FSB now instead of default 266, multi
locked to 10 x and vcore on default. Temps are very low (they always have
been, not sure that core temp or core temp plugin for MBM5 is reading this
45nm CPU right). vcore in Windows seems to sit around the mid 1.2V range.

So, for my 'upgrade' I've got about the same speed as I had with the E4500
only at lower voltage, lower temps, an extra MB of L2 and a slightly more
efficient processor. (OCed E4500 gave me 3180/7128 Whetstone/Dhrystone
whereas the E7300 at about the same speed is giving me 3469/7179.) I'm
thinking that it's probably a bit cheaper to run too.

I haven't been keeping up with motherboards for a year. What now is a good
overclocking mobo for the quad core Q6600? It is used mainly for video
editing and encoding: one 2D video card with dual link (for 2560 x 1600
monitor), 2 to 4G DDR2, winxp or vista (may also setup a virtual pc), many
hard drives. I'm not looking for extreme overclocking, just the most bang
for the buck kind of overclocking (none or slight voltage increase, but be
able to increase voltage more if I want to). Probably something under $150.

It is also nice to be able to put in a faster quad core CPU (the ones
selling for $1K now) a few years later when they become cheap, and then be
able to increase oc more.

Should I get 800Mhz ddr2 (very common and cheap) or something faster? When
oc the board, am I going to hit the CPU limit first or the memory?
