intel socket 1366 question

[notigg]

I built a new computer in May of 2009...... and I picked a socket 1366 motherboard.

Am I kind of screwed out of ever upgrading my CPU with that setup? Because I noticed on newegg their selection for socket 1366 CPU's is very small.

The CPU I originally got it with is the Intel Core i7-920 Bloomfield 2.66GHz LGA 1366 130W Quad-Core Processor

when I was building with AMD I could still upgrade the CPU years later usually... I wonder if I made the wrong choice with Intel.

Looking at the 6 cpus it seems the only decent upgrades would be the 32 NM ones (mine is 45 NM) .. but the cheapest one is over 500 $ . Is the price of those likely to come down before they become "discontinued" ?

No. Your best bet is a used Westmere, which can be found fairly cheap even now.

no. Intel has just been replacing each cpu at a price point with a faster one for the same price.

Unfortunitly, s1366 is considered a enthusiast socket, so intel have alwasys charged extra for it.

later this year, early next year is the replacement of that socket, s2011. CPU prices are expected to be the same still ($500 and $1000).

Will the 1155 socket ever get a CPU that can perform with a triple channel setup? Do motherboards limit the socket 1155 to dual channel? I guess what I'm asking is, will 1155 socket CPUs have triple channel in the future and will I be able to simply upgrade to that new CPU without having to rebuild.

no triple channel for 1155...ever....
socket 2011 quad channel...

Here is another question... does anything you do with your pc benefit more than 0.1% from having a triple channel memory setup? It seems like a lovely gimmick but unless you can saturate the bandwidth you are paying a hell of a lot of money for didley squat, same goes for quad channel as far as i am concerned.

socket 1155 is limited to dual channel as that is all the cpu can support with the pins available. socket 1366 has a lot more pins to allow for the third ram channel and even the newer socket s2011 has nearly double the pins to get to quad channel.

As to if the 1155 socket needs it, then proberly not. Looking at the expected ram speed of 1366 (unchanged since release at 25.6 GB/s Max), it is not much different to 1155's ram speed of 21 GB/s Max, mainly due to supporting faster RAM.

Just a note but even with the 1366 platform having triple channel ram I did a test between the two when I had both side by side and because of the advanced memory controller in the SB it did better at clock for clock speeds and with memory speeds the same as well... And when OC'd the SB really shines and out paces a 1366 system even more... To me triple channel ram was good for its time but newer tech dual is king but cant wait till its in quad form...:thumbsup:

I may try to find where posted this test and link it later this evening... Here is the link...

Also an exert from it...

Just ran Aida64 on both of my machines at the same clock speed and memory speed then even ran the 2600K with the memory at 1333mhz... Both sets of memory at the same timings... Note also the I7 920 was at 191fsb as opposed the 2600K was at its stock setting of 100...

2600K @ 3.8Ghz 1600mhz mem
mem read...18786mb
mem write..19229mb
mem copy...20825mb
mem late...46.4milsec

I7 920 @ 3.8Ghz 1530mhz
mem read...15618mb
mem write..13743mb
mem copy...20083mb
mem late...53.5milsec


Extra test...
2600K @ 3.8Ghz 1333mhz mem
mem read...16316mb
mem write..18588mb
mem copy...17771mb*
mem late...54.1milsec

Only instance the I7 920`s triple channel memory beat the 2600K was with it running slower speed of 1333mhz in the copy part of the benchmark... BTW you dont want to see what the 2600K will do with it @ 4.6Ghz and the memory @ 1866mhz... It will flat clean the I7 920`s clock... Just for shits and giggles I may buy a 2500K just to see if there is much of a difference between it and my 2600K... (bet not much)

This is relevant to my interests, as I'm looking to upgrade a desktop server for our lab, built in early 2009 using a 1366 mobo (Asus P6T Dlx v2).

we currently have the same CPU as the OP (Bloomfield 920 2.6ghz), so I'm assuming the 32nm Gulf Town 6 core CPUs would be a significant enough upgrade?

The 3.2 ghz clock on the same Bloomfield cores doesn't strike me as sexy enough for our needs.

 

[vshah]

i've got a P6T v2 dlx with a 920 as well. it annoys me a little that I only got one processor out of the socket, but at the same time it's more than fast enough for anything I throw at it, 2 years later.

i'll probably skip s2011 and upgrade my cpu when the next enthusiast socket comes out. i'll satisfy myself with a gpu upgrade sometime before that.
