Xeon L5639 Overclocking on X58

[hasu]

i7-860 is LGA 1156.. L5640 is LGA 1366

Rampage Gene III is LGA 1366, correct?
How about this?

That is 1366 but please tell me you are not gonna go spend $234 on a used board?

That would be a lie, if I say that

Edit1: Hopefully, I can sell my 1100T for such an insane price

Edit2: Looks like it is i7-930

http://ark.intel.com/products/41447/Intel-Core-i7-930-Processor-8M-Cache-2_80-GHz-4_80-GTs-Intel-QPI

i7-930 is newer and both are based on 45nm, but ..

i7-860 speed ranges from 2.8GHz to 3.46 GHz @95W (has VT-d)
i7-930 speed ranges from 2.8GHz to 3.06 GHz @130W (no VT-d)

Why is such a discrepancy?

 

[Burpo]

That i7-860 is LGA 1156 Lynnfield vs the LGA 1366 Nehalem..

"Intel is going to support both platforms, LGA-1366 and LGA-1156 for the long term.." (haha!)
"Intel indicated that LGA-1366 CPUs would be binned higher so you can expect higher overclocks and obviously higher top end frequencies."

Pretty funny to read this old article..

Since I mostly use AMD, it gets pretty complex with intel! See the difference between L5640 vs E5640.

The difference in overclocking isn't that big between the two sockets.

As for support though 1366 did get more of it.

You were able to go from a quad to a six core cpu in the same socket while lynnfield never moved past quads.

Mine too! The X58 with my Xeon will see me fine until at least Skylake-E.

 

[ClockHound]

Oh nooooooes....those 5675 prices keep dropping....must resist...()

And the 5690s too! Oh gawd, where's that damn Skylake-E speculation thread?

 

[Burpo]

I bet $140 will buy one of these.. He's got a few

You're not helping....Yes, you are! No, you aren't! Yes, you are...

 

[ClockHound]

OK...let's say I'm weak. And I spring for the 5675....will I want to spring for the 5690 too at some point?

Yeah, it's 140 watts stock, but it's 3.46Ghz at stock! The mult must go to a billion!

 

[Burpo]

lol.. 26.. not a billion..
I want a 5675. I still say that's the 5Gz. chip..

I bought two for my server @ $120 each. But the chips came in just a bubble wrap and no anti-static or case!

One or two ways to prove the theory. But, it's still going to take some volts, unless it's a golden unit like your 5650. Getting cheap enough to play the silicon lottery just for the gigahertz of it.

Yikes! Nice way to treat $1200, er, $120 chips. How much extra for the anti-static bag, $20, $50?

Guess you're not going to overclock them and prove/disprove the 5G theory...

No way! Last time I overclocked was a Celeron 300A (and another 366MHz to 500)!
These are being used in a server! Nice upgrade to the original E5506 (but they were brand new).

 

[Trinamo]

I see that the X5650 is a 95W TDP part vs. 60W on the L5639. Since both are less than my 130W 920, either should be an efficiency improvement.

Are there some "known good" settings / voltages for a decent OC on the X5650?

Thanks again.

I run a completely different system than you guys but used this thread for OC'ing my 5650 with a lot of success.

I'm running Bclk @ 200 with Turbo mode enabled which allows it to peak 4.6 on two cores and 4.4 on the others. My Vcore is a tad higher than I'd like and a tad higher than my original stable setup due to a typo that I think cause a little issue but I have it stable again.

Blck 200
Vcore offset + 240mv
Turbo enabled
Spread spectrum disabled
Stepping Enabled
DDR3 Voltage 1.5
IOH Voltage 1.10
QPI and Uncore +240mv
Memory Ratio set to 6


I had Bclk set to 204 and it would run IBT, Cinebench, etc but would freeze during Battlefield 4. All stable at 200

 

[Burpo]

That's where I'm running also.. With everything enabled, 200bclk is. stable for everything.. It can bench higher, but programs I use start to get wonky (crash to desktop etc.). Rendering blu-rays takes more than an hour & temps are in the 80's the whole time. I'm @ +.250 volts & going any higher, it eventually throttles.

In HWMonitor, do your package powers peak at 95W or do they go up to 109W?

 

[Burpo]

95


Edit: Oops, yes.. Max is 109..

 

[Trinamo]

I wonder if I'm just getting a funky reading or if I broke it when I had that typo.

 

[ClockHound]

109W here in funkytown 5660.

 

[Blue_Max]

Well, my 5650's arrived and plugged in, running stock so far. Would love some advice on:

- best overclocking tips
- best app to monitor the CPU for temp/wattage

 

[MongGrel]

I tend to use HWMonitor/CPU-Z myself for watching things.

It's pretty much a couple of the standard ones.

The previous 10 pages. sounds like a lot but it really isn't. Quite a few helpful screenshots and a few methods that are stable. It's going to be trial and error unless you get lucky and can jump straight to what BURPO and I are running or higher. oh, be water cooled.
