Can I install any LGA-1366 Nehalem-based Xeon into an old i7-920 system?

[Jack the Stripper]

Which series is the best?

 

I get these from the wikipedia website.

Xeon 3000-series (uniprocessor)

LGA-1156 Clarkdale (MCP, 32 nm)

LGA-1156 Lynnfield (45 nm)

 

LGA-1366 Bloomfield (45 nm)

LGA-1366 Jasper Forest (45 nm)

LGA-1366 Gulftown (32 nm)

 

 

Xeon 5000-series (dual-processor)

LGA-1366 "Gainestown" (45 nm)

LGA-1366 "Jasper Forest" (45 nm)

LGA-1366 "Westmere-EP" (32 nm) Efficient Performance

im using Westmere EP (E5620) , they perform the same as there same clockspeed I7 counterparts ,

but lack IGPU´s and have more cache (not 100% shure , but they shud have a bit more) 

 

i can recommend the E5620 , performs very well , 4c8t , 2.4~2.7ghz and only 10$

Look here at Intels ARK site. These should be all Xeons that fit your FCLGA1366 motherboard. I wint as high end as I could without breaking the bank.

Mucho's Gracias, but I count 65 CPU's on the wikipedia website.

 

But that ARK website filter is damn fucking awesome.

 

 

 

[asand1]

You can try other families of Xeon while using the FCLGA1366 filter.

All 6C, 12T FCLGA1366 processors, only one of which is an i7.

Just reading some posts here, wrote down some notes.

 

 

x56xx(less clocked) uses less power then W(better binning?)

w36xx hex core

w35xx is low end, no better then AMD Athlon

55xx and 35xx are locked multipiers

56xx blow 1155 cpus out of the water

Only 1155 that can compete is the 4790k and it's literally just a side-grade. The X58 are very fun to overclock but to the novice user they could be a bit of a hassle. I would only go with X58 if you plan to overclock, once you overclock one to 4.3GHz you essentially have a stock 5820k.

Quote

you can literally get a 40-50% overclock on most all of them which is insane and that is when you are basically getting 4790k and 5820k performance on the cheap.

Quote

So yeah, get a X5650 or a X5675 (75 has a couple more multipliers allowing high overclocks without as much BCLK or with turbo off but they cost a little more).

$80-150

No need to buy an 80 or 90 a 75 will give you all the multiis you need. So only buy an 80 or 90 if the cost is about the same. Otherwise just save your money and get a X5650 but you have to have a higher bus speed using it because you have less multis to work with.

Quote

Definitely get a 6 core. X56** and W36** are all 6 core. Main difference between the 2 is that the X series have 2 QPI links which means they can used in dual CPU configs.

4.3 is literally the max they can go. I got one to 4ghz that require pretty serious cooling.

On this chipset bclk affect everything. So you cant just run prime95 when stresstesting. Its good for a start but you have to test both in games in gta 5 to make sure.

Also its not the same as 5820k stock. Maybe its the same in cinebench. But in real scenarious you get a serious QPI-Link speed.

I am the first to load in all cs go maps with x58 motherboard. So its faster than 5820k on some things.

Yeah, 1.5-1.8X ram speed is what I recommend for QPI Link on the i7 you can do 2X but its better to do 1.5-1.8 on the Xeons. I ran mine at 4.3GHz 24/7, most of them will do that. That is why it's not really worth buying more than just a X5650 or maybe a X5675 unless you just happen to find an 80 or 90 for the same price or maybe $20 more. I had a 4.5GHz that I ran all my benchmarks with and also a 4.7GHz profile but I never ran the 4.7GHz for more than anything than screenshots or the occasional benchmark, once you go over 4.3GHz on most of them you start really having to crank the voltage.

The X5675 can achieve all the same multi than you would need as the 80 and 90 but can be found cheaper. The X5650 I think is limited to 20  (22 with/for turbo). The X5675 is 23 with 25 turbo. The stock clocks are of no consideration since you are overclocking and telling it what to run. You will instead use a bus speed in the 180-220 range and then a higher multi.

Quote

For instance.... with turbo off. I run 196X22 on an X5675 which gives me 4.312GHz. With turbo off on an X5650 you are limited to 20 multi so you could only achieve 3.92GHz.

So to hit 4.3GHz on the X5650 you would need to run with a higher bus speed, so instead of 196 you would have to push 215...  215X20 to achieve 4.3GHz with turbo off.

 

I learned a lot. I need to let it all sink in.
