Hello,

Intel Core i5 3350P, S 1155, Ivy Bridge, Quad Core, 3.1GHz, 5 GT/s DMI, 69W, Retail

VS

Intel Xeon E3-1230 V2, Ivy Bridge, S1155, Quad Core 3.3GHz, 8MB Smart Cache, 33x Ratio, 69W, Retail


Useage: -
13 Bay NAS Server running various other apps including transcoding.

MB: Something on a B75 Chipset? Looking for minimum spec and features to keep the power down.

Low idle power is important. I'm not planning on a server chipset or ECC memory so which do you think?
 
FYI: my work server is a HP 110 G7 with a E3-1220 Xeon. When resting it draws about 40w and when poked with a stick this can jump to 180w. Mind you it does have 2 x ssd and 5 x hdd (2tb wd blacks) and a raid card.
 
Looking at http://extreme.outervision.com/PSUEngine and adding all the components I'm planning on having it reckons a 300W draw if everything is running at 90%.

That's something I don't expect to happen that often.

PSU wise I'm just going to use something I have at present and measure the loads then get the most efficient / low mains draw unit I can.

So I'm really just looking for pro's and con's on each chip, or as I'm not planning on using ECC RAM does it not matter?
 
The E3 1230 V2 is the one to get. Faster stock clocks, larger cache, hyper-threading with the same power consumption. As for price/performance it's the best chip the Ivy Bridge 1155 series. I bought one a few weeks ago to use with my spare Z68 Gene-Z. I'm looking forward to testing it with a - offset voltage, I've read these undervolt nicely. Something to consider if you'd like efficient / low mains draw.

Thanks Bluntwrapped,

I'll be interested in your results. Are you planning on putting them up here?
 
I'll maybe need to wait a month or so before I can grab the rest of the parts I need. At the moment things are a bit tight :( As soon as I can get everything up and running I'll post my build and results.

This is an interesting read:

He's running with a -0.130V offset shaving 20W from his load draw compared to stock.

I'm tempted to try overclocking mine too:

I managed to get a bare bones build up and running over the weekend with my new Xeon E3 1230V2. I'm very pleased with the results so far. I only have 2gb ram installed at the moment but it's stable under IBT with less than .9mv. I'll need to do further testing once I've bought and installed the ram I'm planning to use.

I've been testing this with a refurbished GTX 480 I picked up a month or so ago here at OCUK. I have under volted this too down to .988mv and .825mv idle. It's not the most efficient GPU to pair up with the E3 1230V2 but with these voltages I'm pulling less than 80w from the wall idle.

Looking forward to doing more tweaking this week. Hopefully I'll be able to reduce things further.

The xeon e3-1230v2 is going to slaughter the i5. Unless you're doing anything heavily threaded ie say transcoding 8 streams at one then choose the i5.

THe xeon is too much bang for your small application

EDIT:// Must swap out my signature - I'm on a 1245v2 now with quick sync :D
 
The E3 1230 V2 retails for about the same as the i5. If you're not planning on using the iGPU on the i5 then I'd say you'd be just as well to get the Xeon. Obviously there is very little headroom for overclocking but at stock clocks it's already incredibly quick. Comparatively running a few benchmarks it's about as quick as a i7 SB clocked at 4-4.1Ghz.

limited headroom ? It's a fair bit in my experience ... the e3's like the non k's accept a +400mhz turbo overclock.

ie my e3-1245v2 has a max turbo set to 4.2ghz and if you want to be really greedy you can add to it with BCLK so 4.5ghz(peak with 4.1ghz base) is possible but risky
 
In comparison to the K unlocked multiplier it's pretty limited. Less than 4Ghz with the 1230 V2 with 108 BCLK. The 37x turbo only applies to core 1 and 2. Under stress across the cores the multiplier drops to 35x.

How did you increase your turbo to 4.2Ghz?

http://ark.intel.com/products/65729/Intel-Xeon-Processor-E3-1245V2-8M-Cache-3_40-GHz

The max turbo for this is 3.8Ghz. Without having an unlocked multiplier I don't know how you've managed to get things that high.

Google limited unlock.... It depends on the board you have.... p67/z68 or better I think.... Here's a link that explains it

I didn't know about this either .... First I thought of trying a BCLK on my Xeons and i7 but then bumped into this limited unlock feature. TOTAL WIN if I ever saw one :D

Yeah awesome info thanks man :) I honestly thought I was limited to 35x and 37x multi. Will have to have a play when I get home tonight. I'm using my Gene-z so hopefully this is something I can do.

I did notice max ratio outside of turbo but the layout of the BIOS is a bit different to my other Gene-z. Were you able to adjust turbo multiplier or did you have to key a manual ratio?
 
Ah nice one think I've got my head around it now after reading the link you posted. I'll definitely need to have a go this evening!

Edit: I'm missing various settings after 'upgrading' my BIOS. Can't have a play until I get this sorted :(
