SB-E [C2] Stepping

Hope so, I've been waiting 2weeks with the rest of the pc built and just staring at me in the corner!

Yea! I'm in the same boat except I have not bought anything! Afraid of DOA components and return periods :(

Will get my WC orders in this week (partially) will probably need to wait a little longer for 2 x 7970 Blocks and back plates.
 
The old stepping supports VT-x, which is "hardware VT acceleration" as you put it. What it lacks, and is added in the new stepping, is VT-d. VT-d is only useful if you have hardware that supports this functionality and want to be able to use it in a virtual machine (i.e. not likely for most people on OcUK).

That isn't to say that it's not important, but it's not the deal breaker most people make it out to be.

While this roughly true there have been reports that these clock better (ASUS forums). It is an enthusiast chip and Yes I can have 3 or 4 virtual machines going sometimes.

If you don't use Virtual machines or you have no plans to enable VT-d then this will never bother you!

To address the other point you make about "..hardware that supports the functionality..."

Well this is not true.
from Wikipedia
"... guest virtual machines to directly use peripheral devices, such as Ethernet, accelerated graphics cards, and hard-drive controllers, through DMA and interrupt remapping."

Which is probably handled by X79 chipset

So in essence your virtual machine will behave very much like your computer when talking to hardware, i.e. rather than emulation it would use the Ethernet controller or GPU directly.

TBH for 500£ I'm not willing to buy a chip which clearly does not perform as originally intended. Intel's SKU specifically stated VT-D which was hastily changed in response to RMA's. Some people on Overclock.net have been promised RMA's directly from Intel (apparently).

EDIT:
Theoretically
Not that I will - but since I only use Linux I will no longer need to use WINE to play games. The VT-D will enable me to play any game inside a Windows Guest Virtual Machine with pretty decent frame rates :D

Like I said, I don't dispute the fact that it's an important feature to certain people. I'm merely stating that people have been confusing VT-d for VT-x, and mistakenly claiming that hardware assisted virtualisation doesn't work. Clearly, this isn't the case!

Now, the lack of VT-d isn't going to cause a problem to the majority of the target market i.e. the enthusiast who is big into gaming (yet somewhat ironically, it does cause me issues, but that's my reward for being an early adopter). I can totally understand why you would be unwilling to pay £500+ for a CPU that does not support this feature, especially given that you (inSilica) have mentioned one of the few potential uses where VT-d is essential.

I'd also like to point out that I'm not trying to be contrary or otherwise cause annoyance; I'm just keen on making sure that people understand that it isn't a crippling issue, that makes the CPU worthless and unusable, and causes misery and shame to all concerned.

Edit: I should have been more precise when I said "hardware that supports the functionality". What I meant was, it's up to the motherboard manufacturer to enable VT-d functionality in the chipset - if they don't, it doesn't matter which stepping of the processor you have, you'll be without VT-d. HP have a history of removing access to features like this from their BIOS/EUFI, for example having a system with a Core 2 Duo that supports VT-x, on a chipset that can support VT-x, and preventing the end user from enabling the feature.

Sounds like there was some confusion :D . You are quite right some people have confused VT-d and VT-x.

I think we are saying the same thing :)

...

If you don't use Virtual machines or you have no plans to enable VT-d then this will never bother you!

I'm quoting rjkoneill from the watercooling thread which was made last night


My stock landed today but I have been busy setting up tech labs stuff and in meetings :(

They will be on the website tomorrow, expect an announcement thread from me.

Also, expect very surprising prices ;)

... maybe reading too much into it but could be part of the stock?
 
Seeing some more speculation

http://www.evga.com/forums/tm.aspx?m=1374207&mpage=1

and a possible name change to 3939k???

yea I saw this too! Could explain why some competitors including OCUK are just flat out of stock.

It will probably come with a gagging order in that case ... which explains the silence

Note quite, an QXXX s-spec codes are used only for engineering samples. According to the product change notification PDF in the OP, QBV9 is the S-Spec of the C-2 3930K qualification samples. The S-SPEC etched on the retail processors will be SR0KY.

Thanks for the info
 
I think the 3939K was a typo, and that the original author didn't check for typos before copying the first entry. Simple mistake to make, pressing "9" instead of "0" :)

If the name were changing, I would think that 3935K or 3940K would be more likely. Just an opinion though (plus that is the only place I have seen 3939K mentioned - even posts I have seen from people with samples only call it 3930K )

i7-3960X 3.3 GHz BX80619I73960X SR0GW 918749 C-1
i7-3939X 3.3 Ghz BX80619i73960X SR0KF 919886 C-2

Good spot
Makes me wonder if the rumours around a name change to 3939K are true then?
maybe there will be a new entry soon, just hoping it stays at 499 or below and not some silly price premium..

And going by this logic the 3960X should be replaced by 3939X.

Well, the CPU has SR0KY printed on it, and CPU-Z has Stepping 7 in the info.
Let me know if there is anything else I could check to confirm it is C2.
Haven't tried overclocking yet.

That's definitely C2 . Congratulations . Now let's hope it will go mainstream in the UK

Stepping 7 in CPU-Z is what I've seen in the latest rounds of C2 bench's

So the 3939K rumor was definitely bull
 
inSilica, I hope you are right.
Btw keep in mind that this was in stock under C1 so maybe C2s are all over but we don't know yet. When I called the store they were clueless about the S-spec codes.
Key for me was that it is a tray version of the CPU, that one was never in stock in Germany before, at least while I was tracking, so on 20th it was the first time.

N00bbuilder79, not yet, running stability tests currently on stock (3.8ghz turbo). I use watercooling so it has extra layer of complexity, checking for leaks.
I don't expect difference from C1, and with the silicon lottery you can never be sure what contributes to a better OC.

I see you are keeping the OCN thread updated too :D

Just to draw your attention to this screenshot:

EDIT:[Just don't use that many volts]

I am quite confident though :D (at least I hope because I'm fed-up of reading - I always buy processor + motherboard + RAM) TOGETHER, and last - I'm fussy about DOA and since these break most frequently I like to test them ASAP.

Also planning a WC system with 2 * 7970's thrown in

How much RAM are you using nuhi?

Intel say 32GB max but I've seen people running 64GB [including mate] (either way I would like 4 * 8GB stick or 2 * (4 * 8GB) Dominator 1600)

inSilica, hehe yeah I was checking all possible threads on this CPU's whereabouts, then to my surprise it went unnoticed.
That screenshot setup is crazy - even if that works for me, the heat output would be too great for anything other than bragging.
I'm using "just" 16GB, Corsair Vengeance, 4x4. Nothing fancy, may upgrade later if reviews show benefit, which for memory it hardly matters for the things I do.

Yea, I mean I don't do much gaming but will have a quad radiator setup and you know WC setups, I just can't be bothered to move it about.

The Dominator kit is only 20£ more than the Vengeance (1600) hence the choice but anything > 1600Mhz to my limited knowledge :) will be a waste of money for SB-E at least.
 
Not so far..
They don't know when the next delivery is or if it will be the new C2 stepping, at least that is the situation at 9am this morning

This is tech torture

Lol!

There is some talk on hard forums that 3930 is in short supply in contrast to the 3960X (obviously because of price), (shortage includes the C2 stepping). Stock supply is said to pick up late January and first week of February.

There is also some confusion. I still believe nuhi has a C2 chip!
 
If I had had my case I think I would have done the same. I have a box of bits sitting in the lounge, didn't put them away as I enjoyed being able to see my bits even if I couldn't do anything with them!

That is a nice spec there, be interesting to see what clocks you get with all 8 RAM filled, I have gone for 32Gb of the 17000C9 G.Skill matched sets, so in a similar situation..

well all I have to do is choose the case now
corsair 650D, or 600T or or swallow the pricier option and get the TJ07

gonna sleep on it I think and see how I feel tomorrow - enough excitement for one day!!
I've been quite ... not to dampen the mood but I've waited the best part of a year for the 8 core processor - OK I'm willing to put up with the fact they turned off 2 of the cores but I can definitely wait a little longer for a Retail.

Not overkill! on RAM :D

I'm going for 8*8GB (2 x quad channel) only 1600 though - will be pulling one or two ram disks out of this

And with respect to a case, mine is being built in a P280(antec) water cooled + 2 * 79(50[or]70) - Will be creating a project log once I have most of the bits and pieces which should be end of next week (fingers crossed).

You have to set a limit somewhere! The money you save on the less important bits is the money you can spend on the actual tech.

EDIT:
Crazy price on 3930K at OCUK - wow bargain at 431.99 SO TEMPTED!

Gibbo, do you know of any policy with Intel for swapping the C1 for C2? I only ask you as I bought my chip from yourselves and just wondered if you had heard anything.

There is some speculation on this.

However replacement only available through Intel directly. Give Intel UK a call

would be gratefull for any info regarding this aswell, my chip has the odd bug where it wont overclock using the multiplier, its not really working like a K chip!, apparently its going to be fixed with a later bios update, but if i can swap it for a newer stepping then that would be better.

Im not sure about this!

From the reading I've done this bug you mention is reported as affecting the 3960X only. Have you tried cooling around your CPU? are you on air?
