/dev/random on Ivy Bridge CPU

Hello,
I have a Sandy Bridge instead of an Ivy Bridge CPU. Ivy Bridge has a new instruction for true random number generation at 500 Mbit/s.
If I type cat /dev/random, it only shows a few lines of random characters, increasing a bit if I move the mouse.
I'm curious, if you own an Ivy Bridge CPU, does /dev/random make use of it and spit out lots of random data very fast?
So please do an experiment for me, if you are using Linux on an Ivy Bridge CPU: Please let me know how much output "cat /dev/random" gives for you
(Note: NOT /dev/urandom!!).
In other words I'm just curious if Linux makes use of that potential, or if it only uses mouse movement and networking and stuff.
Thanks.

When I use rng-tools, and rngd.service is running, /dev/random is crazy. But like you I get about five random lines if it is not running.
Edit: BTW, I don't have a /dev/hw_random or a /dev/hwrandom.

Buying Z77MA-G45 with an Ivy Bridge CPU

Hi
I would like to buy Z77MA-G45 with Ivy Bridge CPU. It isn't supported by default BIOS (1.1), and I don't really have any possibility to upgrade BIOS with a supported CPU (yes, I've read the topic).
So now questions:
- is Z77MA-G45 runnable with Ivy Bridge just to get to BIOS and update from an USB drive on in a similar way?
- is there any marking on mobos' box that could indicate the BIOS loaded (the BIOS version itself, lot number, serial number, something similar?)
TIA

Hello TIA,
The board will handle all Ivy Bridge CPUs without any issues regardless the BIOS version shown on the CPU support list.
However, it is highly recommended that you perform BIOS update to the latest version once the system is up and running for best result.
Sincerely,
Warner
Warner without trying to hijack the thread woudl that also apply to Z77A-GD65?

Just ordered iMac and shipped, but it will use Ivy bridge CPU???

I heard new CPU will be used for iMac, should I refund and order again? Or it has already installed???

No. It will have the old processor which is an Intel Core i% or I7 also known as a Sandy Bridge.
The Ivy Bridge has not been released you so you can't get it.
You can return it and wait for the Ivy Bridge that is your chose.

P67A-GD65 (B3) Ivy Bridge CPU recognition

Hi all,
I have had this mobo for about a year, and yet I havn't used it, but just recently, I purchased an Ivy Bridge 22nm processor to which to 'try-out' the mobo not knowing the BIOS version. [oops!]
Installing this particular processor, and connecting everything else to the mobo, will it POST despìte the fact that I am unaware of the BIOS version? - Will I able to 'get-into' the BIOS at least? - Any damage to the CPU and/or mobo if turned on and if BIOS version is not the appropiate one?
The thing is, I cannot test the board as I don't have a Sandy bridge CPU at this moment.
In await of any reply,
Thanks.

Quote from: Froggy Gremlin on 27-July-13, 10:39:03
No POST or entering UEFI/BIOS without a supported CPU, sorry. There is almost no advantage to an Ivy CPU in a P67. Yeah, you get prettier BIOS screens, but how much time is spent in there? Recommend to put a Sandy 2700k in it and it will destroy what an Ivy can do performance wise.
I'm running a 2500K in this same motherboard. I had the intention to grab a E3-1290V2 from work when we reconfigure & update the systems there. But it seams your advising against that?
B!

Ivy Bridge CPU 4 short beeps then Power down

Hi I just got a I7 3770 and when trying to get the board to post it beeps 4 times (short).
I was wondering what the beeps are telling me.
I am using a Z68 MA G45 (B3) board and back in February I asked about a compatible bios and was sent a link to a beta bios that should work.
So I took the risk to try it as I can always get another board if needed as I am building a cheap pc for a family member using the Pentium G620 that I was using till the Ivy Bridge was available.
Hoping I don't need to buy a new board as the 7 series are a little more expensive here. But the extra features will be worth in the long run.
I have asked MSI online support to confirm if the bios is ok but as they are not there till Wednesday as they had 2 days off I wont know for sure till tomorrow.
I thought I'd try anyway as I got impatient.
Thanks for any help.
Kevin

I put the Pentium G620 back in and it would not stay on and no beeps at all.
Then I swapped the I7 back in and still the 4 beeps.
So I took a break and decided after an hour searching the web for help I would try the Pentium one more time.
And this time it worked ok and brought up the bios message that said there was a CPU/memory change and to press a key to go into the bios to reset the info.
So as it's late here (Melbourne Australia) I left the pc alone after switching the power off and will continue tomorrow.
So tomorrow I should know if the bios I have is compatible with the Ivy Bridge and if not I will get a 7 series board.
I just have to return the cheap board I brought and will get a credit towards another board.
Pity about the bios but that's technology for you.

P67A-C45 SUPPORT Ivy Bridge CPU

P67A-C45 B3 SUPPORT Ivy Bridge CPU

I tried to flash the 5.1 bios via the DOS method but it killed the board. It looked as if it had gone well. It rebooted and flashed the secondary flash and all. But when it came to the final reboot the board was totally dead. The CPU and PSU fans just moved a bit and nothing happened. I tried resetting CMOS by holding the switch to empty the caps, removing battery for 10 minutes and pushing the CMOS button at the back. I even shorted the reset jumper on the board.
I tried the control + home start with both amiboot.rom on USB stick and then burnt to a cd.
I pulled out the board and stripped it trying to see if I could get a beep or blink from the diodes while putting CPU and memory back on. Nothing.
I then bought a new Z77A-S01 IvyBridge board and now I´m happy again.
There´s a bit more in this thread https://forum-en.msi.com/index.php?topic=159446.0
I probably did something wrong OR the board was faulty but I just didn´t feel like fighting with it anymore. It’s a bit over a year since I got it and perhaps I could have gotten the shop to fix it but by now I am so tired of the problems (boot errors) with this board that it feels like a relief to put it in the garbage.

Sandy Bridge to Ivy Bridge Upgrade in 2012

PC World reports:
"We also know that Ivy Bridge will be compatible with the LGA 1155 socket--great news for Sandy Bridge owners, who may not need to buy an entirely new motherboard to upgrade."
http://www.pcworld.com/article/246688/processors_what_to_expect_from_cpus_in_2012.html
Does that mean I will be able to put an Ivy Bridge CPU into my W520?

@JDay,
I am not sure if it applies for laptops but desktop CPU has BIOS whitelist. I came across threads that when customer tries to upgrade the CPU (even in the same series) the BIOS does not recognize the CPU after upgrading due to BIOS whitelist.
Thus I am not surprise if they have BIOS whitelist for CPU on the ThinkPads.
That happens when you try to stick a processor in a motherboard that shipped with a BIOS that was shipped with firmware intended for processors with less cores. Not a whitelist just the firmware freaking out because there were more cores than it was made to handle. This issue was very common when hexa-core Phenom II CPUs came out and could be fixed in all but a few cases (about 1% of motherboard models didn't have an update) by simply putting the old CPU back in and flashing to the newest BIOS firmware revision.
EDIT: If a BIOS update is required you can bet someone over at the MyDigitalLife forums will release a modified one, especially if it is requested. That is the same place you can find a non-whitelisted BIOS for most ThinkPad models.

H61MA-E35 (B3) 4 beeps on POST with Ivy Bridge

Just built this machine, it has never posted and I am getting a 4 beeps and then a reboot whenever it is turned on.
I looked it up online and found it's either it's something to do with a timer(?) or the most probable cause being the current bios not supporting the Ivy Bridge CPU I'm using.
So basically, am I indeed correct in thinking the CPU isn't compatible with the current BIOS? If so, is there anyway to flash it without a cpu/using the incompatible CPU? As I don't really want to buy another processor just to use this one.
Thanks for any help.

As you don't know what bios you have it is hard to say but it is an old B3 board so most likely it has no Ivy Bridge supporting bios. You could add S/N to say for sure. If it has a bios not supporting Ivy Bridge there is no other way than using a Sandy cpu to update bios or asking MSI or a pc shop to do it for you.

P67A-GD55 (B3) bios update to Ivy Bridge, question regarding PCIe-3

Hi,
Ive just updated my P67A-GD55 (B3) to the 4.0 BIOS for Ivy Bridge and I am a little confused as to whether of not I will be able to benfit from PCIe-3 support on a Ivy Bridge CPU?
I intend to run 2 x GTX 680 in SLI, will I still be limited to PCIe-2 of can my board now take advantage of PCI-e 3?
Many thanks in advance.

For PCI-E 3.0, a Z68 G3 series mainboard with an Ivy CPU would be needed at the minimum. So far, you are not really missing anything anyway. PCI-E 3.0 doesn't seem to be reported as providing all that much of a performance benefit with current apps, programs, and games.
Having tested GTX 680 on the P67, I must say it is in itself running PCI-E 2.0 very impressive.

Z68MA-G45(B3) Ivy Bridge Bios

I contacted MSI support to see if they where going to update my BIOS (Z68Ma-G45(B3)) to work for the the Ivy Bridge CPU and they Sent A link to this beta bios (link removed, not for public).
I tried to flash the BIOS using the forum bios tool but the tool would not let me set up my usb device saying it was not a compatible bios file.
So I unrared the file and used the M-Flash utility in the bios and it flashed correctly.
The next thing is to see if it actually will work with a Ivy Bridge CPU when they are released. I assume it will but you never know.
Oh and does anyone know of a release date for the Ivy Bridge CPU'S?
Kevin

Last rumor was sometime in April.
Added: Before the forum is overloaded with questions about Ivy Bridge CPU support for all the 6 series mainboards, check with MSI Tech Support here;
http://support.msi.com
PLEASE don't bug the forum with 'any news' posts, all are MSI product users here just like you, yes, even the admins & mods. A good place to watch would be the Beta BIOS Section found in the Overclockers. Undervolting, Modding Corner Section of the forum. Jack does his best to keep it updated as he receives anything to post. PLEASE, don't bug him about it either.

Discuss Quick Synch in Ivy Bridge Laptops?

For those who must use a portable edit solution, powerful laptops are a must for PPro. New reviews on the latest Ivy Bridge equipped laptops are indicating a possible huge leap forward in performance, due to the "Quick Synch" feature included within the integrated graphics onboard the CPU. Even with this feature disabled, the Ivy Bridge CPU seems to have a great performance encoding video. See this link: http://http://hothardware.com/Reviews/Intel-Core-i73720QM-Ivy-Bridge-Mobile-Processor-Revi ew-/?page=4
I do not know if Adobe PPro is written to take advantage of this,or not.Can someone who knows please comment ?There is a mention of third party software that allows a discrete GPU to be used at the same time as the onboard 4000 Intel graphics, ( normally the integrated graphics would have to be disabled to use a discrete video card). The review shows the Intel 4000 graphics almost on par with a discrete CUDA card for some tasks, and blowing the CUDA card away in one video encoding task!! Could it be possible to combine a CUDA card with the onboard Quick Synch for killer performance of PPro or AEffects??!! The article states that many software companies are writing their programs to take advantage of "Quick Synch"....is Adobe one of them??
The Ivy Bridge tested in the review reaches 3.4 GHz on all 4 cores under load with the turbo feature. Combined with 1600 speed memory maxxed out and two internal Cherryville Intel high speed SSDs, I'm wondering how such a laptop would perform on the PPBM test!!!
As a laptop user,due to frequent travel, I would appreciate any thoughts by all you guys who know far,far more than me....Harm, RJL, Bill, et al.......
Am I right to be excited???.....or, will "Quick Synch" with Adobe become " Quick Stink"!!!
After posting this, I saw the following thread in the sidebar from a year ago : http://http://forums.adobe.com/message/3693326#3693326 This mentions an Intel plug-in to enable PPro to use Quick Synch , and AME as well. Also, Lucid Virtu software to allow access to the integrated graphics while the CUDA card is on.
Have there been any newer developments with this...esp. with laptops and the newer Ivy Bridge CPUs?
Message was edited by: JFPhoton

I am not sure if the SDK plug-in option is still available for the Quicksync with Adobe and no idea if it works with CS6. This was something on Intel's site and that they developed or atleast listed with the walk through. Beyond that I have not checked in months.
Unless the Virtu software has been updated, it does not work with Cuda based applications for Cuda acceleration.

Ivy Bridge Support for 610-1130f (H67 - WJ1 Motherboard)

Intel H67 chipset supports Ivy Bridge but requires a BIOS update.
Does HP plan to release a bios update?
Is there anything we can do to get them to offer an update?
I really wish HP would support it.
I've love this machine even more with a new Ivy Bridge CPU and HD 4000 graphics.
Has anyone tried installing a processor to see what happens?

Hi,
Some third parties have released bios updates to support the Ivy Bridge product. A lot of regession testing needs to be done on the older motherboards. I would suspect that HP will release new models of the TouchSmart with Ivy Bridge support.
The Intel 2600 is a viable upgrade for your TouchSmart.

Ivy bridge only quad core?

I may be quite possibly switching over from mac to pc this summer and am looking to build a workstation. I'm fairly new to customizing and building and am trying to understand all these differences between xeons, i7's, sandy bridge, sandy bridge-e, ivy bridge, etc.
For a while I was sold on the idea of a dual lower ghz xeon-e5 workstation for my 3d/compositing work, but I still see a lot of people pushing the idea of an overclocked i7 as being an worthy competitor for a lot of the type of work I do.
Anyhow, I've been led to believe that for my applications, which can usually use a lot of multicore multithreaded operations, that more cores are better. I've been looking at an 8-core cpu or possibly dual hex. I've been told to wait for ivy bridge, especially for graphics work and performance, but I notice statements that ivy bridge cpu's have a maximum of 4 cores? How does this leave them stacking up against previous sandy bridge/e 6 and 8 core cpu's?
I'm a little confused about this, why intels next gen microarchitecture would have less cores? Can somebody help clarify this for me?

TDP. Microsoft wants to limit the TDP of their chips (see http://nl.wikipedia.org/wiki/Thermal_design_power) and thus has to either limit the clock speed or the number of cores and L3 cache.
You may wonder what all this means and I can understand that. Look at it like a car, where the manufacturer limits fuel consumption to X gallons per mile. He either has to limit the top speed (clock speed) or limit the number of cylinders in the engine block (number of cores). That is what Intel currently does.
For AE and 3D applications, number of cores is critical, for PR clock speed is critical. Since you mention octo-cores, there is only the i5 Xeon with 8 cores. Bulldozer or whatever other AMD 8-cores there are on the market now or in the near future are absolute crap in comparison to Intel.
FYI, I'm waiting for the Ivy E version, 22nm models that lift the 6-core and 15 GB L3 limit of the current SB-E and will give us 8-cores and 20 GB L3 cache. No idea when it will happen however.

Hello i buy a new macbook air white i5 ivy bridge processor and when i play a game the cpu themperature is 88-100c it is normal?

One thing I should add. While "normal", it doesn't make it preferrrable that you should be always running near the maximum capability of the unit. The new 2012 MBA's are outfitted with CPU's that have a maximum running temp of 115 degrees C. (the 2011's were rated at 100 degrees C.)
At, or near this point, the CPU will shut down the system to safeguard from overheating. Right under this point the system's fan will be running at top speed. Any mechanical device, run at or near it's capability will undergo accelerated wear. Just how much in this situation is unknown. as such, I don't use my MBA as a full-time gaming rig. I try and keep it sensible.
The MBA is not really designed for gaming, but it's competent performance sometimes lures us to use it as such.
