Was suggested that I post in here to maybe get some help from the Experts who run dual XEON setups. Sorry for the double post.
Just want to make sure I picked out a good setup/comments/suggestions.

Thanks,

I don't have the experience but ...what will this be used for?
Don't get those Intel heatsinks.
You can use any socket 1366 cooler (within reason, not too big). I have Thermalright HR-01's here on a Tyan S7002 board.
Get an SSD drive for your OS maybe?

Each CPU has 3 channels for memory bandwidth, so you need at least 6 sticks to get the full benefit.Quote:

Motherboard looks great and we have some fans of supermicro here.
Any 1366 coolers you can recommend? I believe I read somewhere that the screws on the XEON boards do not fit with the regular 1366 coolers. I know that someone in the comments on newegg bought the 1366 XEON intel cooler and it didn't fit with his regular 1366 on a non server board.Quote:

Thanks.
Dunno either, but I see your point. CPU2 would be asking CPU1 for memory. The board has 6 slots, so I added 6 sticks of 4 since I didn't know if 3 would do it. Also, it's triple channel, so it looks like I need to populate all 6, and might as well do it 4GB vs 2GB. Does the ram look ok?Quote:

The memory you have picked out looks great. I would gauge if you need 12GB or 24 GB depending on what kinds of work loads you plan on running. 12 should be fine for crunching, with 24 being better if you start getting into database apps and other more traditional server type work.Quote:

Will def be doing DB work (about 4GB DB). This is my dev machine, so basically a match of what I have running in production, only from Dell, so actually newer since those are Harpertowns.Quote:

I see 3 4 pins??? Also single rail vs triple. Thanks again.
Welcome to WCG- your DP experts:up:
Noctua has heatsinks I use for my DP system
Thanks for the comments guys. Looks like I'm left looking for a compatible PSU and some heatsinks. The HR-01's are way too big (I remember jcool having to cut his..lol), but open to alternatives assuming I don't have to use a special mounting kit etc. I'm not too worried on 5-10c diff between the coolers either, so if that's all they help, not enough for me to double the cost - besides this MB won't OC. Kinda the same for me on SSD vs HDD, $260 for 2 intel x25's @ 40 GB isn't enough to give up 210G's for my OS drive's in raid 1 which are $95 - I also have about 5 spare 250's lying around (better safe than sorry). On the PSU I'm having a hard time. Can't I use a PCIe 6+2 pin for the extra 8 pin for the CPU (no clue)? Anyways, I'm having a hard time finding a compat PSU on newegg.com (the Corsair 1000HX looks like it might work though).
Looks like I might hit $3k here. LOL
Thanks again guys, you are great.
Most Thermaltake PSU's at 750W or higher have at least two 8-pin connectors. The Corsair HX 750W has four 8-pin connectors.
Cases are a matter of personal preference. I have a Supermicro ATX dualie system and use a E-ATX server case. Even though you're looking at an ATX board, you may one day decide to upgrade to a bigger one. Things can get pretty cramped in a mid tower case with dual heatsinks. Although server cases tend to be more expensive, they generally have a lot more room. Chenbro makes some decent ones that aren't too pricey.
Awesome. Still a bit confused, does the 6 + 2 pin pcie work as a connector for the 8 pin CPU or do you need the 8 pin pcie? Either way, thanks for the tip on the thermaltake, I think I will go with this one (since I need a pice 6 for the video unless the 8 pin will work):Quote:

My Apevia is huge and won't fit under my desk unless sideways. That is primarily why I am looking for a smaller case for this new build. Haha. I will checkout the chenbros.
I'm pretty sure that 8 pin pcie's have a different pinout then the cpu onesQuote:

Ok, what PSU's are you guys using on Tylersburg? I'm still having a hard time finding one with 2 8 pin outputs that are NOT pcie's. I did check the thermaltakes, can't find one out of 20 with 2 8 pin powers that are non pcie. Am I missing something?
If the 8-pin connector says "EPS12V", then you are fine. EPS stands for "Entry-level Power Supply Specification." This connector was developed specifically for server boards. It's sometimes referred to as the "+12V Connector" on spec sheets. This is different than the PCI-E connector.
You can also combine two 4-Pin ATX12V connectors to form an 8-pin.
I need to correct what I said earlier. The Thermaltake PSU's usually have at least two 8-pin "PCI-E" connectors. My apologies.
Yeah, can find plenty with one, just not 2 which this board requires. Hopefully someone with dual 5500's chimes in on what they are using. Thanks man.Quote:

Just cruising down the list of 600-700w psu's
for instance here's an OCZ one with an 8pin and a 4 pin
http://www.newegg.com/Product/Produc...82E16817341018
and one from Antec
http://www.newegg.com/Product/Produc...82E16817371021
you can use a 4-8 adapter for the 4 pin one which will be just fine while running at stock speeds and voltage.
in the specifics look for the connectors section and it should say something like this
1 x Main connector (20+4Pin)
1 x 4 Pin ATX 12V
1 x 8 Pin EPS 12V
9 x Peripheral
9 x SATA
1 x Floppy
4 x PCI-E
Thanks for the help again guys. I have a email into Corsair as we speak. I couldn't find any cables in their store.
Has anyone ever used one of these?

It takes 2 molex power and puts them into a 8 pin 12+V power. This would def open up my options on PSU's if it works. I am a lil bit worried about using a built in 4-pin (ATX power) to 8 since those are hard wired and generally meant to use one or the other but not both. Also the HX 1000 is overkill and I doubt I will breach 450 watts load. I do need at least 2 pcie 6 pins for the video though (in case I add another 5750 at some point).
Quick specs:
2x 80w
6 drives, 4 HDD, 2 DVD (round up and say 100w)
MB (no idea of wattage) 100w
Single 5750 vs dual 3870's (may go dual 5750's though) 108w max (single)
4-5 fans
So around 500ish? If so looks like the 650HX will work fine with the 8 pin molex adapter.
PSU's...I just had a look at some of mine...coolermaster 900 ucp, coolermaster 1100 ucp, pc power & cooling 910 all have what you need and if not current are recent
seasonic x series, enermax modu87 700 and 800, are both ok, modern and efficient too ....especially if you run in the 50%ish load band. For efficiencies once you find a candidate go to http://www.80plus.org/manu/psu/psu_join.aspx and check it out.

Read.
Any questions left, just ask. Provided that you will crunch on it, I'll answer :p:
Oh, and with that config listed above, you are not going to use more than 300W, ever. 7200RPM drives are at ~7W operating each, and the mobo takes 40-50W tops with pwm losses.
well jcool's post handles most anything.
I run a dual E5520 setup as a work computer for rendering. It's good for a work computer because it's easy to cool vs. an overclocked setup. At home I run a w3520 overclocked at 4.2GHz. I have them both crunching away on the WCG. Look me up "trn-xs" if you want to see how the two setups crunch (pretty equal, I think the w3520 is doing better.) both are running 100% and I'm on vacation this week so it's a good test of crunching.
Thanks for chiming in you all. This board is great and you all are very helpful, which is saying a lot since many are not.
Can someone comment on the molex adapter I ran across ^, or should I use a different adapter for the majority of psu's that come with a 4-pin and 8-pin power? I simply don't see the need in spending $100 extra on a PSU that has the connectors when I'm not even going to come close to using all that power when I can buy a $100 cheaper PSU and a $15 adapter.
Last question is, should I go with ecc 1066 vs 1333? I'm not sure the price difference is that drastic, but if it saves $100 might be worth it.
i posted a couple of PSU's under $100 that had 2 CPU connections just with 1 being a 4pin, or you would also probably be fine if you already have a PSU and used the molex one you posted.
Here's the adapter i was talking about

You've been a great help especially. I really appreciate it Blauhung.Quote:

I ended up going with the OCZ you picked out and dropped the ram to 6x2GB Corsair 777 (better latency, but no HS). Wintec has a nice 1066 T-kit that is even cheaper with same latency and HS but it's not due back till Mar 1.
Thanks to those who helped answer my questions directly. :up:
$2400 and done - bout 1k cheaper than my harpertown rig with more-faster ram, cpus, a non asus MB, and a case that will fit under my desk. Cheers.
now since we helped, you must pay us back by installing WCG and joining our team:p:
The adapter Blauhung linked will work great, same ones I use.Quote:

The OCZ PSU is a little overkill, but you definitely got the headroom to put a heavy GFX card in there later on, so that's a plus.
Stock coolers are, well, crap - let's just hope you aren't sensitive to noise :D
Hope to see you back here crunching with us :up:
Stock coolers are crap. I installed dual true 120s on mine with scythe sflex fans. Keeps temps in the 50's under 100% load. Kinda overkill but they are quiet.
