PC enthusiast customers and companies running corporate datacentres looking to buy into the new Sandy Bridge-E platform may want to wait a little while before handing over their hard-earned money to Intel. The initial batch of C1 revision Sandy Bridge-E processors have a bug – “errata” in Intel terminology – in them with VT-d, which means that hardware accelerated virtualization doesn’t work properly with them (software only mode is unaffected). The feature when working properly, allows all hardware acceleration to work on the hosted operating system (virtual machine). This would allow things such as hard drive controllers to work, plus applications such as high-powered 3D games, typically First Person Shooters, to run at nearly full speed and the full Windows Aero desktop to be displayed on the hosted OS, as the hardware features of the graphics card can be used. Therefore, working VT-d is a critical feature for these kinds of applications.

Yeah... mine 920 is also more than enough...

But seriously... this is a huge problem... it renders them pointless for server market...

Till X79 mates? :D

I'm still happy with my 4GHz Lynnfield.:laugh:

At least Intel caught it and let people know before the processors were released.

written with a strong degree if bias :banghead:

The express chipset may not contain a vast amount of feature differences over Tylersburg, but the platform on the whole is significantly better, sharing such praise wouldnt be beneficial to your hating tho wouldn't it? :slap:

There's been no bias and no hate.

If you want to buy a new system with these significant bugs in it, go right ahead, Intel is preparing to sell it to you. Everyone else will have been glad to have been informed of such a problem so that they can avoid getting stung by it. :rolleyes:

correct ive actually starting using virtual machines and the like to test out some what ifs and potential problems also good for getting some older apps to work , so the fact Sandybridge E C1 silicon has a bug that makes that worthless im glad to know i didnt plan to use SB E but its still good to know about said problem.

but i would guess qwerty you love Intel so much any ill will or article must be biased right?

its a tech problem it was reported thats how this works, its also mentioned a fix is in place it just wont be ready for a short while. so dont get your panties in a bunch.

Damn :( part of why i am so interested in something with 6c/12t or 8c is the virtualization possibility's, i do agree though, it is very nice this info has come out before launch but i can't help but be unhappy that if sandy bridge E is my choice i would not get an upgrade this year.

Just goes to show that just like the original Phenom was bugged, Intel is just as open to bugs as AMD.

I'd have to guess that Intel will throw the majority of these C1 chips to OEMs, and tell them to not have an option to enable hardware VT-d in their BIOS/UEFI.

While I do agree that it is nice Intel is informing people before launch about this issue, it isn't so much like the "Barcelona" debacle you all reference. In that case, AMD helped motherboard manufacturers issue out a bios to fix the problem (albeit with about a 20% performance hit), and it really didn't affect any home consumer users. Intel motherboards cannot receive a BIOS update to fix this (most likely), nor the SATA issue on early 6 series chipsets.

This platform is looking more pointless everyday. It has no IPC benefit over 1155 despite twice the memory bandwidth. No pcie 3.0, and now no virtualization. It has 2 extra cores. That's it. Big whoop. You can fit two extra cores on 1155 with 22nm just fine. I get why they didn't learn their lesson with 1156 and 1366. 1366 came out first, people got attached to it and what not. This time though it's reversed. 1155 has a massive market saturation advantage, and so far 2011 isn't offering squat over it's cheaper already available cousin. If 2011 sells like shit just maybe Intel will go back to a singular consumer platform.

Unfortunately because 2011 is planned to have a very long life even if it didn't sell a single unit in the first year there's plenty of time for it to do well enough for Intel to consider it a success. Hell even if it was total flop I'm wondering if they still wouldn't try this divided platform crap again and again.

They'll do it again and again. The 'enthusiast' high end socket has other customers, namely corporate and government customers looking for low-end workstations. It's useful to pull that aggregated segment out of the 'normal' low-end and mid-end segments. At least useful enough for a large corporation like Intel to make it financially viable, in some way.

Well that's crappy news. I was waiting for X79. Plan B involves Z68 and 2500K; looks like that may have to do for a couple months.

Yeah, it's not good news, is it? The release of a proper, bug-fixed CPU is now so far away, that if someone wants to build a system now, they might as well just go ahead. Possibly waiting a short while to see what Bulldozer is like is the only thing worth waiting for. That's being released soon, but I can't remember the date, now.

I think there's a fair bit of exaggeration going on. Intel would not release a server-class processor without VT-d functionality (equivilent of shooting one self in the foot). It has a bug, but I highly doubt it is completely dysfunctional.

Yes, I've been wondering exactly how broken this is too. IMHO it's pretty bad for them to respin the chip.

Remember that AMD said Bulldozer would be released 90 days aproximately after the motherboards, so it's just around the corner.

I think for anyone thinking of x79 for gaming rigs should really just wave it by. A 2600k and a top end gfx card will reap virtually the same benefits. So sure, you can go uber multi gfx but whether the cards run at x16 or x8 doesn't make a lot of real world diff (http://www.tomshardware.co.uk/pci-express-scaling-p67-chipset-gaming-performance,review-32164-9.html).

With Ivybridge coming in Spring (and AMD's reputed tweaks for BD) there will be more 'polished' tech available. PCI-e 3 will be more mature with perhaps some gfx vendors using it and you'll get tri-gate tech on IB.

Really, Intel screwed up by making SB so good. I bought X58 and SB cpu is better. You buy x79 now and in 6 months, IB will probably be better.

Nah, x79 seems like a waste to anyone other than those that really need it's functionality yet from all the web reports so far, it seems very hamstrung.

Only problem is "hardware accelerated" VM's. The cpu's are fine for everyday stuff, no idea why some people think the thing might not work at all.

Well, that makes the decision easier. It was one thing to lose SAS support - future motherboards would have it and I could just swap it out. But with the importance of VT-d (VM's are my everyday stuff ;)), no reason to get SB-E now. I'll just have to wait for C2 along with SAS-equiped motherboards.

Hopefully they hold back SB-E Xeons. It is vitally important there, or the bug is overblown as Ford theorizes.


Come on AMD! I have nothing until 2012!
