I have an old Intel DQ965GF motherboard (rev. D41676-305) with an
LGA775 socket but does not have a CPU installed.

According to these links:
<http://www.intel.com/support/motherboards/desktop/dq965gf/sb/CS-025970.htm>
<http://processormatch.intel.com/COMPDB/SearchResult.aspx?Boardname=dq965gf>
I should be able to install one within the following CPU families:
Intel Core2 Duo Desktop Processor
Intel Pentium Desktop Processor
Intel Celeron Processor
Intel Celeron Dual-Core Processor
Intel Pentium D Processor
Intel Pentium 4 Processor
Intel Celeron D Processor

Which one is the fastest CPU? Where in the U.S.A. can I find a
reputable business that sells such used CPUs?

You can look at Passmark multi-threaded benchmarks, to
find the processor from that list which is the fastest
for say, video transcoding. The other aspect, is fastest
single core speed. And that's a factor of both the
generation of the processor, as well as the clock. For example,
clock for clock, the Core2 is probably 1.5x that
of a Pentium 4 or Pentium D.

The Q6600 was a midrange (cost) processor with quad cores.
The PassMark rating is 2973. If I compare that to an E6600
dual core, the PassMark is 1909. An X3220 Xeon has a
PassMark of 3118, and should really be closer to the
Q6600 (same speed, and number of cores).

Sometimes the server-class processors, have things
like twice as many TLB entries, which gives a slight
bump on some benchmarks. If it wasn't for that, the
X3220 might be nothing more than a re-branded Q6600.

http://www.cpubenchmark.net/cpu_list.php

If we were looking at an old Pentium 4 running at 3.6GHz,
a Q6600 core at 2.4GHz would roughly match it on
integer. And then, the Q6600 has more cores than the
Pentium 4 does, so the PassMark would be at least double.

The Extreme processors had an Extreme purchase price,
and even used, the owner may try to recover the initial
investment. I wouldn't expect to see one of those
for $50. Whereas the more run of the mill Q6600,
you can likely find those used.

I wouldn't attempt to locate a "new" processor for
LGA775, because they'd want too much money for it.
A "pull" is probably OK, as it could have come from
a lease machine, and not been overclocked. If you
get a Q6600 from Ebay, then chances are it's been running
at 3GHz all of its life. Instead of the stock 2.4GHz.

LGA 775 also works with the:

Intel Core2 Quad

It's the first processor listed at the first link you gave. These are
harder to get. Won't find them on Newegg but will at eBay where used is
far cheaper than brand new. Buy from a seller that gives a 2-week
refund period (and note if eBay marks the auction as protected by their
eBay protection plan in case you can't get a refund from the seller).
To eliminate problems with overseas sellers and high return shipping
costs, and because I'm in the USA, I filter on US-only sellers.

When you get the used CPU, use Prime95 to burn-test the CPU. There's
http://www.passmark.com/products/bit.htm but it's not free. It has a
trial download usable for a month but it might be crippled. This one is
free: http://www.intel.com/support/processors/sb/CS-031726.htm.

Mine is slow as a dog compared to an X2 AMD. It is cooler than the
AMD, though, a lot, which is OK, as always I run that AMD hard when I
do, and the Intel stays on always but isn't pushed. They both cost me
the same off Ebay, not much to almost nothing. Doing it again
differently shouldn't be hard to figure.

Unfortunately I cannot use an Intel Core 2 Quad processor because my
motherboard is rev. D41676-305.

I didn't even check that column :-(

It almost looks like a VCore power limit or something.

Some motherboards, they didn't put enough phases and a big enough
current output capability in the VCore circuit. Maybe your board
is limited to 65W processors ?

But if we look at the table for the older processors, then check
the 960...

http://www.intel.com/support/motherboards/desktop/dq965gf/sb/CS-025970.htm

The 960 is a 130W processor.

http://ark.intel.com/products/27522...4M-Cache-3_60-GHz-800-MHz-FSB?q=pentium d 960

So maybe it's a BIOS microcode support issue as far as Intel
is concerned. The Windows OS has a microcode loader as well,
so if the BIOS doesn't have microcode patches for a recent
processor, the OS can do it.

Still, it's hard to see a pattern there, as to what the
limiting factor is on the processor.

The datasheet I have here for P965/G965/Q965 shows FSB1066 support,
so that's not it. And there are some FSB1066 processors your
motherboard does support.

Maybe the E6700 is the best you can do. It's probably
faster than the 960, but not by much, and it wastes
a lot less power.

http://www.intel.com/p/en_US/support/highlights/dsktpboards/dq965gf

That lists the Core 2 Quad as supported. Also:

http://processormatch.intel.com/COMPDB/SearchResult.aspx?Boardname=dq965gf

lists a Core 2 Quad as compatible -- but for the slower ones, like Q6600
and Q6700. It doesn't list, for example, the Q8800 or Q9650. If you
click in the left pane to filter on "Intel Core2 Quad Processor (2)"
(there are 2 entries in the table), click the "+" button next to each to
see what is the minimum BIOS version needed to support that processor.

Oops, I see now. Your mobo revision is a -305 and that isn't in their
list for Core2 Quad or the Xeon Quad. Looks like you can't use quad
cores. The onboard CPU regulator and caps for that early mobo revision
probably can't handle the current load for the extra 2 cores.

So it looks like the fastest CPU in their list for your mobo & rev is
the 2.66 GHz Core2 Duo (the Core2 Extreme isn't listed as supported by
the -305) but you still might have to update the BIOS. Alas, they have
some exclamation marks next to some CPUs. The E6700 2.66 GHz Core2 Duo
has a "!" but I don't know what they mean by "Compatibility details
differ per process revision". My guess is with BIOS rev 4462 for the
-305 mobo rev that you have to use either the SL9ZF SL9S7 specs of the
E6700 Core2 Duo 2.66 GHz CPU.

While they have some filters (by CPU model) on the left, it would make
it a lot easier for those that have an actual mobo to filter by its rev
to see what CPUs could be used on that one.

So what happened to the old CPU that was in this old motherboard? If
the old one fried, and if not because the thermal paste was forgotten or
was poor grade and dried out so the CPU overheated or because the CPU
fan stopped spinning, how do you know a new CPU won't also fry? Since
this is an "old" mobo (which hints it's been sitting around for a long
time unused), why wasn't there ever a CPU in it?

This colleague at work gave me the motherboard for free but does not
know what happened to the CPU...

I figured that since I need one (used, if available), I might as well
get the fastest possible.

You can find the E6700 on eBay. See:

http://www.ebay.com/sch/CPUs-Processors-/164/i.html?_from=R40&_nkw=core2+duo+E6700

The new ones are expensive. See:

http://www.ebay.com/sch/CPUs-Proces...o+E6700&_dcat=164&rt=nc&LH_ItemCondition=1000

But you can but a used of for a lot less. See:

http://www.ebay.com/sch/CPUs-Proces...emCondition=3000&_nkw=core2+duo+E6700&_sop=15

For me, I'd filter by "Paypal accepted", "US only", and "Returns
accepted" to find the more reliable sellers, as in:

http://www.ebay.com/sch/CPUs-Proces...yPal=1&LH_PrefLoc=1&_fspt=1&LH_AllListings=on

Just be sure NOT to scroll past eBay's "More related items" divider as
those match only on some of your search criteria.
 
Are you sure the motherboard works?
Click to expand...
My colleague thinks that it works. He just does not remember what he
did with the CPU.
In any case, that's one reason why I want to purchase a used CPU...
 
He remembers the board works, but not what happened to the CPU?
Hmmm... I'd be inclined to see if I could borrow a compatible CPU
first just to check out the board. That would be better than buying
one and then discovering the board is no good.

If worse comes to worst I'll just put the CPU up for sale on eBay...

But if the regulators are fried on the mobo (which is what happened to
an old mobo for me) then the CPU will get fried. Just figure on buying
a used one for under $30 to limit your financial risk and if it fries
then that was the cost of the experiment.
 
Hello folks, I know the post is quite old, but anyway, might is serve to someone,
I've got the Intel DQ965GF since 2007, with a Core 2 Duo E4400 (2GHz dual core),
lately have found some used Q6600 at fair price, and decided to revive this old machine (with a SSD, stucked at SATA 2).
On the intel information page they say that:
-Only starting from some revisions these mobo could accept C2Q.
-Mine is AAD41676 402, on the official page compatibility starts at 602.
-After a BIOS update, the latest is from 2009.
-I'v installed the CPU and for now all is going well.
So for someone looking to upgrade it's Guardfish Q965 Express CPU, with a board version AAD41676 402 and the 2009 BIOS update IT'S OK :)
