Hopefully, Dookey has better luck than I am having. My Biostar board does not like this processor at all. It also didn't like a 970 or an E5530, so I think this is a board problem. The codes in the newer versions of this bios don't look like anything I have seen before.

I am torn on what to do next. I really don't want to buy another X58 board, but I also don't want an idle hex core.
 
Biostar, yuck. I bet the board cant handle high TDP cpus

EDIT: specs say 60w TDP nevermind haha
 
I've loved my Biostar boards, but I've never asked them to go outside their "range" before.
 
It was the best I7 920 board I had when I was running 4 of them. It just doesn't support Gulftowns, Gultown Xeons, or Gainstown Xeons apparently. High TDP was not the problem. I love this board, which is why I hate to give up on it.
 
Well that begs the question, what mobo is most likely to support a Gulftown Xeon?
 
Hopefully an Asus P6TD Deluxe (what Dookey has) or an MSI X58 Pro (what Dookey is getting.)
 
I'm getting comfy with the idea of upgrading my main rig with an hex, and then later picking up a second one, moving them both into the SR-2

The last part probably happening around the first of the year.
 
I know for fact the EVGA classy supports the L5640. Hopefully one of my boards will also.
 
jebo's Gigabyte something or other runs his E5640. I am tempted to swap my 970 out for this L5640 just to see if it works.

What I am about to say might be hard to hear, but this forum is about friendship with honesty.

Right now you have two working kidneys, and one working L5640.

Swap. You don't need 2 kidneys, but you do need another SR2. :p
 
Ha!

Ohhh you fit rite in here.

I might also say to pick up your free GenMay pass. I think you will like it there :p

I like the way you think...that is basically what I was thinking (minus the kidney part... :)). I do have an E5620 floating around the country somewhere that will eventually find its way back. I am running dangerously short on other part like HSFs, memory, and PSUs believe it or not. I'm sure that can be rectified, though. I may do some temporary trading to check compatibility first. We'll see...
 
Okay, my L5640 is here and I just installed it into my MSI board. Installing Vail as I type this. We'll see how it goes.
 
cool! No special bios right?
Can't wait for the results.
If they overclock to 3.9~4ghz its a no-brainer buy for folding. :cool:

I'd consider anything over 3.6 GHz gravy. Remember, these things only have an 17x multiplier plus turbo, so 18x total. You aren't going to get a 222 bclk to hit 4 GHz.

If you are installing an OS, you have me beat. That is extremely good news!
 
Booyah! Success with the install, just started -bigadv at stock clock.

This is with the BIOS that shipped on the board. Got an openbox MSI X58 Pro-E from Newegg for $134.99.

Now on to overclocking! More to come.
 
I'm still waiting for my L5640 to get here. I have a Asus P6T so I hope it works.
 
Ok, at 3.4ghz for now. I'm going to let it run a bit to be sure it is stable then I'll push on some more.

Bad thing is that I pulled a 2684.
 
Looks like 3.66ghz is my limit. System keeps rebooting but won't even get to bios screen if I go above that. I suspect it's my CX400 corsair PSU holding me back or my MB just doesn't like BLCK above 215. It was an open box and that may be why someone returned it. All in all though I'm pretty happy with this upgrade. Here's what I'm running now for my WHS.

WHS Vail preview
Open box MSI X58 Pro-E motherboard
Corsair CX400 PSU
3gb G.skill DDR3
L5640 hex core
Coolermaster Hyper 212 plus HSF
1TB WD blue caviar
Sparkle GTX 460 768mb

Voltage is 1.38 for the cpu, bet I could push it farther with a stronger PSU. Temps on cpu at load 69C-74C. Not too shabby.
 
All of the Asus P6T* boards should support these chips if that MSI does. My Biostar experiment was truely a worst case scenario, since this board doesn't support anything but I7 920's... :)

You don't have turbo on, and the chip should support it. I forget what the MSI bioses look like, but you may have to set the multiplier to auto and enable Speedstep or something to enable turbo. I'd probably back you bclk down before you do it, though. 215 bclk is pretty darn good for any X58 board, so I think your board is fine. Get turbo going and you should be tickling 3.9 GHz.

You may have convinced me to take a flyer and crank my Vcore way up on my SR-2. I am only at 1.28 right now. Getting up to just over 1.3 didn't help anything, but I didn't try just cranking it up to 1.35+.
 
Snuck my OC to 3.75ghz. Seems to be stable. 220.5 BLCK per cpu-z.

Oh yeah, board has 3 PCI-E slots. I'm going to put 2 more GTX 460s in as soon as I get a new PSU.

I'm telling you, turn on turbo mode. I know those processors will do 18x, and I am pretty sure the MSI bios doesn't let you just set the multiplier to the max turbo multiplier.
 
Dookey is right there if he would turn on turbo... 18 x 220 = 3960
 
Dang, the guy on ebay now has these going for 379.99. I'm so close to pulling the trigger and putting one in my P6T Deluxe...
 
Ok, I'm keeping this one at 3.7ghz for now. I can't push it higher because I have to pump 1.4v + into the chip for 3.8 or above and my little 400CX PSU can't take it. If I don't fold with the GTX 460 then I can easily run 3.8ghz, but I lose too much PPD to do that. Overall I'm happy with 3.7ghz and load temps below 80C.
 
If a motherboard supports the 980X, should it work with this chip?

That's what I'm thinking. The bios for my MSI was updated for 980X support. In windows it just tells me it's an Intel chip, but not that it is a Xeon L5640.

My 980X shows up as such in windows.
 
Think this would work in my MSI X58M then? The X58M does support the 980X
 
Now I just have to decide if I want to go hex core or add two more GTX460s
 
Are there different steppingstone on these chips?

Looking at a CPU ID 206CO.
