Best LGA 775 CPU

[i_build_nanosuits]

I believe back then Intel's "Quad Core" CPUs were just two Dual Core Dies bodged into the same package. Would explain the power draw...

The powerdraw came from the fact that these are built on 65nm and 45nm...die size was a bit bigger too i believe, architecture was simply much less efficient.

But even then, the powerdraw of something like a Q6600 quad-core chip under load is around 105W to 120W depending on the settings

which is comparable to a ''modern'' AMD ''quad-core'' CPU such as the athlon 860K or FX-4300 for example...so it's not that much of a problem.

The problem like i said is that there were A LOT of cheap ''office'' type motherboards with very flimsy hardware on them that just can't handle a load like that. Those were designed with pentium D and low frequencies Celeron (duo) processors in mind...they just weren't meant to run a Q6600 or a Q9650.

Still is the case today, some flimsy 3 phase H81 and B85 motherboards can't handle a 4.4ghz i7-4790K without trottling the CPU...those are meant to run i3-4160 and i5-4460.

Back then since motherboards technologies weren't as great as today the boards tends to just overheat and die instead of trottling down the CPU therefore it's easier for board manufacturers to just not include quad-core in supported CPU list and put a microcode to make sure it won't work.

Not really. I've watched people playing CS:GO in YouTube with E7400s and Q6600s and the Quad was noticeably smoother and the framerate counter proved it. Besides, I've read on lots of forums about Dual-Core users struggling when near smoke or in firefights.

So what was your results? New shinny q9550 . I have one, excellent CPU. Did it help? Are your frames still dropping around smoke?

Yes. I couldn't tell any difference from the Duo.

 

Maybe I bent a single Mobo pin

Maybe it's my PSU

Core 2 Extreme @ 3.2 GHz Quad Core

I (HAD) an LGA 775 motherboard and the best CPU it supported was a P4 HT.

I have more LGA 775 mobos, one support P4s and PD 8xx CPUs, Others supported everything from P4 to C2D. NONE of them support Core2 Quads.

IIRC that whole issue is one of the reasons Intel now introduces a new mainstream socket every two generations. LGA 775 was around for a very long time and caused a whole heap of compatibility issues near the end of its service life.

Early 775 boards maxed out at 800MHz FSB speeds while late model boards like the 790i and X48 could pull as high as 1600MHz. RAM was a big one too since DDR3 came out a big push was to switch to it and that created all sorts of confusion.

The way it's done today is more expensive for the end consumer but much less complicated I think.

P45 easily passes 1600MHz FSB. Both of my motherboards with the P45 chipset can easily do 1800MHz.

P45 is another great example of a late model chipset, for sure. My ECS Black can hit 1750 or so and that's passively cooled.

I left it at stock bus speeds to keep my post length in check lol.

Settled with a used Q9550 for 30 bucks.

45nm Yorkfield with 1333FSB and 12MB of L2 cache. A quad core without any of its features cut in half.

What do you mean?

What do you mean?

Because they're expensive during its days and many wanted one. Intel made cheaper version of it with less cache. There is the Q8xxx and Q9xxxx series. Only the Q9x50 has the full 12MB.
