xeon e5 2670 overclock

[slayer2005]

Just bought a xeon e5 2670 plus mobo for 300 of the bay.
Anybody have experience with getting a good OC out of these chips .
It is a unlocked multiplier test chip.

Cheers

I highly doubt it's unlocked in any shape or form. I have two ES Xeons, a 1366 and a 2011 and both are locked to heck.

Not only that but Intel derp the strap on 2011 so you can't touch that and my one won't even do a 102 fsb.

I have several E5 Xeon samples and not a single one is unlocked.. Except for the VERY special one I have coming on Monday..

From the auction listing
Interestingly the chip has the following marking on it...intel confidential QBF5 2.6GHZ Costa Rica 313128105...Those in the know will realise this is a unlocked multiplier intel test chip

Now i dont no a lot about these chips but im just about to do a new build and thought id take a punt on something differant.

 

[ALXAndy]

Well I will be shocked if it's unlocked but hey man, let us know how you get on

any idea about the name? I am interested

Just messaged the bloke and he got it from a high up intel guy so looks like I got
A bargain.

Well basically you've got a 5960x Ivy on your hands which is why I doubt so much that it's unlocked.

I just hope for your sake he's not talking about the turbo multi which is unlocked and can be set to always on, giving you 4 multi.

My Xeon runs at 2ghz and I decided to use it for my Hackintosh where it's as happy as a pig in excrement. Love sitting here running a encode and watching the cores all heat up in HWMON

Got double the score in a CPU benchmark of a 4670k, so a fantastic little CPU

I asked him if he OC it he said no but he said the mate he got it from said it will
Get to 3.5.
Got to wait a week for it then buy me 970 so I will report back.
And if u google confidential chips they are apparently engineers chips which
Are illegal to sell.

 

[ALXAndy]

Yeah, hence ES, Engineering Sample.

They're supposed to be returned to Intel after testing and what not, but seldom are. People don't usually sell them though as it's as risky as hell as Intel have themselves well covered.

I've seen trays of them on Ebay before though.

What board did you get? phases are going to be crucial on that chip if you're overclocking it.

Intel DX79SR

 

[ALXAndy]

Hmm, not so great then.

Mind you, it was about the best effort they ever made before calling it a day.

Ed. Should explain. That board was at least 200mhz shy of any other extreme board, IE the RIVE and MSI BBXPII.

Mind you, it has to be said, she's one sexy girl.

So it's a **** board?

 

[ALXAndy]

No no dude, certainly not.

It's just a typical Intel board, a bit meh when it comes to overclocking.

Good high end boards like the Rampage and the Big Bang will allow much higher clocks...

I would imagine the limitations of your overclock will probably be heat related any way. 8 cores and an extra 8 threads is quite a lot to pack into a die that size.

I mean my Xeon runs between 0.6 and 0.9v most of the time, and even with a tiny little 60mm cooler on only ever peaks at around 50c on the hottest core. But then it's only clocked to 1.7-2ghz max.

LOL No comment at the moment

Intel boards were always sold on their solidity and reliability rather than features. You also may find that you cannot use the Xeon on the Intel board as it was never officially supported. That board also is a couple of years old and basing on the support for the DX79TO there will not have been a bios update for a while.

What happened with this cpu then? Did it arrive? Any overclock?

Sorry ain't been on for ages.
Yhea arrived all working good, had a quick play and does seem to be unlocked
But bios kinda confuses me "not a expert when it comes to oc"
Any tips? Maybe I'll have another play with it soon.

Thinking I need to up the voltage but scared I will break it lol

 

[PhysX_OC]

Any news?
I'm curious because I've seen one on eBay and if it really is unlocked I'll switch to 2011.

If you OC it, just set the multiplier as high as possible, and leave the BCLK at 100Mhz, because that affects the RAM, PCI-E and uncore clocks as well and usually causes instability. Any usually it fails at 102-3Mhz BCLK. However you may find this useful: http://rog.asus.com/forum/showthread.php?28069-Overclocking-3960X-to-5-0GHz-and-above You probably won't get to 5Ghz, but I think 4Ghz should be possible with that CPU.
