Hi all

I understand the 755 with the Q35 chipsets which supports vpro, also vt-x and vt-d technologies.


Can anyone confirm if the E6550 CPU supports vt-d which would allow me to punch through the VGA card to a running VM with near native performance ?

Intels ark doesn't say either way. It only lists 13 processers of which some of the E8xxxx and some of the Core 2 Quad are 'valid' S755 vt-d capable.

A second hand E8xxx is crazy money, like 80 or 100 quid. And the supported quads seem to be a rare as hens teeth, and also quite pricy. (I could buy a cheap Xeon server for a similar amount........) But I wanted to use a nice, quiet, powerful enough 755 rather than a honking rackmount beast.

I run a couple of vm's on a 755, its an E8400 though but runs esxi4.1 fine (didnt test 5 yet as its remote). Win2k8 DC and basic linux box
 
Yeah, We run quite a few vms on various 755 boxes, but I'm specifically concerned about punching through accelerated video using VT-d technology. The E8400 does support it. E6550 - many retailers suggest it does, but could be a poor copy pasta job. intels ark omits any indication positive or negative (cynic in me says this is deliberate....)
 
It's pretty much just the same/worth it to buy a complete new system/server for the cost of a frigging vt-d chip. Why do intel suck so hard. AMD puts all the tech in all their chips.
 
Presumably to force people who need the functionality to buy the more expensive processors. I assume that they couldn't be bothered to go through their database of processors to list which features are not supported when they moved to the new ARK system. I agree that it is frustrating - my processor doesn't support VT-d, despite Intel initially suggesting that it did on their ARK, then later changing the entry to say that it doesn't.

Still, what can you do other than buy AMD kit, and suffer the limitations thereof? :(
 
update : seems it does.

Thank you for your patience. I heard back from the group that manages the product and they confirmed that Intel® Core™2 Duo Processor E6550 does support VT-d.

It's good of you to update the thread with the response from Intel. I suppose what would have been nice is if they'd update their database with the relevant information, but I guess you can't have everything :)
