What controls Turbo Core in Xeons?

[txgy]

Can you explain how this is relevant to this thread?
I don't see the connection?

disable INTEL ME and unlock BCLK

 

[Klancs]

Hello everyone, I have been reading all the messages and I can not find the way to do it to my board, I have a Gigabyte X99 Ud4p and a Xeon E5 2650 V3.
On the other hand, as I do not understand much English, I do not clarify either.

Any bios already modified for my badge?
Sorry for the English of google translator.
Thank you.

i have a question for connoisseurs, can the processor E5-1620V3 be hacked to bios without microcodes so that it can go into full boost?

Yes but why?

 

[Cata40]

To have maxim turbo

 

[MOF]

E5-1620V3 is just old technology simple quad core cpu, you can buy better and faster unlocked K cpus with same money.

 

[Cata40]

Its not for me. Now i see its quad core and boost is almost like base
have anybody problems with 2683 and Asrock itx ac?

 

[Klancs]

After flashing the bios modify a mi Gigabyte x99 Ud4p, when entering the shell u load the V3.EFI I get the error: V3-cpu wrong.

 

[sciff]

Klancs the CPU has to have CPU ID 306f2 that is E5 v3 Xeon with stepping 2. Yours is probably 306f1, or stepping 1. They can't be unlocked

 

[Klancs]

My CPU is a CPU ID E5 2650 v3 Es2: 000306F1 Thank you very much for the help.

E5-1620V3 is just old technology simple quad core cpu, you can buy better and faster unlocked K cpus with same money.

The 1620 V3 is a far superior CPU compared to it's i7 4790K/4770K siblings.

Not only does it have 40 pcie lanes, it has a soldered IHS and overclocks to 4.5-4.8 easily.

Remember 1600 series V3 CPUs have its multi unlocked.

Still old tech quad core cpu.

Cheapest 2011r3 motherboard starts form 210$, 1620+mobo 600-650$, you can buy brand new Ryzen 8 core system or 7700K system with same price.

if you catch good deal, yes 1620 can be good option but with those prices...

Guys, I've got two Intel Xeon E5-2696v3 CPUs. I'm planning to buy a dual socket motherboard for these babies and I will unlock them like I have unlocked the one currently installed into my ASUS X99-E WS/USB 3.1 motherboard. I need a powerful workstation that will allow me to render fast in 3ds Max with Corona Renderer.

I need a motherboard with a sufficient distance between two sockets as I'm using Noctua NH-D15 coolers.
There are only two motherboards that satisfy this conditon: ASUS Z10PE-D8 WS and ASRock Rack EP2C612 WS

I want to be sure that there will be enough stability and that the motherboard, whichever I choose, will provide sufficient power for two unlocked E5-2696v3 and will not overheat.

I know there are owners of both motherboards in this thread. Which one should I choose?

Would you recommend ASRock Rack EP2C612 WS instead of ASUS Z10PE-D8 WS which is NOT without its own problems?

To the owners of ASRock Rack EP2C612 WS and 2 x 2696v3:
1. Does this motherboard have a sensor showing the actual power drawn by either CPU? For example, X99-based ASUS motherboards have it, it's listed in HWiNFO as CPU Power and does show actual wattage — I checked that with an external socket power meter.
2. What are VRM temperatures under full load? Should I be worried that the VRMs will overheat during many hours long rendering? The heatsinks on ASRock Rack board's VRMs seem kind of floppy and they don't even have backplates like ASUS's do. Are the VRMs on the other side of the board very hot under full load?
3. Are there any problems with using less than four RAM channels per CPU? I only have four sticks of 16GB ECC RDIMM so each CPU will be working in Dual-Channel mode.

I am only considering ASRock Rack EP2C612 WS because I've been told by several owners of ASUS Z10PE-D8 WS and 2 x 2696v3 that this motherboard is not without its problems. I was hoping that ASRock Rack board doesn't have those and is a better (and cheaper!) alternative.

ASRock Rack EP2C612 WS has better technical support, that's for sure. But apart from that, are there other advantages I should know about?

I'm looking for another v3 processor, but I do not buy it because I have problems with Asrock x99 itx ac!
It does not see the processor E5 -2683 V3, although it's on the motherboard and the processor works on other boards.
I tried different things and it still does not work.
I'm talking to Asrock
That's why I was looking for something else and I found this E5 1620 and I asked about it
Thanks for the info

@Dufus

I have disabled Intel ME for my system... see below for in-BIOS status results (before & after).

Modifications were based on instructions provided in the following thread:
https://forums.anandtech.com/threads/disabling-intels-management-engine-me.2517366/

The system boots and operates the same as if ME were enabled. I see no difference in performance with respect to max power limits applied.
Undoubtedly, further testing and investigation is warranted for which I am happy to assist.

For those that wish to attempt the same... some hints from my success:

1. The Python script provided (me_cleaner.py) did not work on my modified BIOS. I was required to start with a new BIOS, modify it first using the method provided, edit the resulting ROM to remove the SEC Core write-protection (using UEFI Tool), and finally remove the offending Haswell-E microcode using UBU.
2. Running NO microcode with this modification results in all cores locked at HFM (2.3GHz for 2696v3). Turbo'ing to frequencies above HFM (up to and including max Turbo) are possible and works as expected; however, I simply do not see cores falling back to 1.2GHz (LFM) with Windows in "High Performance" mode. Changing this back to "Balanced" results in idle at LFM. And of course, "Power Saver" keeps all cores at LFM regardless of workload. I suspect this has to do with the ICC module this is not loaded...hmmmm

That's because in advanced power settings for these modes there are set different Minimum processor states. 100% in case of High Performance causes the CPU to always maintain at least its base frequency, effectively turning off EIST.






On the other hand, if you set Maximum processor state as 99% instead of 100%, you will effectively turn off Turbo boost! Weird, huh?

By the way, if you set Maximum processor state as 99%, you will effectively turn off Turbo boost!

I set myself in windows balanced to power options and in rendering, when in full stress immediately felt an improvement.
we all had x33 core, now they all went up to x34

Yess i have a good price and solve problems with x99 itx ac, i hoe, who doess see the 2683

A friend bought 2011-3 mobo for $300, 8-core E5-2630L v3 for $150 (which has been unlocked with my help) and two sticks of 16GB Samsung ECC RDIMM for $250. He could have built a Ryzen system for a comparable amount of money, I guess. But here the advantage is that up to a 22-core Intel Xeon can be installed. I'm sure that their prices on eBay will drop at some point in the future.

I do not understand why, the board Asrock X99 itx ac does not see the E5 2683 v3, which goes on other boards very well even if it does not have support on those motherboards.
However, it will be a simpler, playable game for a family member.
So I will take that 1620 and sell 2683, hoping that I will solve the problem, which for 2 months I can not solve it

Even though I stand by my statement that the 1620 is a good cpu especially for gaming once overclocked.

I do agree with MOF, for similar prices you can get a more powerful CPU.

I don't understand why, you 2683 does not work on the AsRock board and does on others. AsRock is really good and supporting Xeon and even early stepping Xeon chips. My AsRock Extreme 4 played nice with ES1 and QS chips.

What are you using the CPU for? I am going to be honest, I only got into the Xeon game because when I purchased them they were cheap. Now that they are expensive and Ryzen is out I would never have messed with them. I got my 2696 V3 for 540 and when I originally bought the 2683 for under 200.

I am thinking of selling my 2696 V3 and AsRock board with an unlocked BIOS (thanks again Canonking) on eBay and see what I get. And move on to a X299 system, really liking the 7820X. 8 cores, strong IPC, and overclocks to 5.0.

 

[Cata40]

Not work on Asrock X99 ITX AC, but work on Asrock X99 OCF or Asus x99 deluxe 2 the 2683 xeon
I tested the same components (samsung ecc memories, GTX 770, 2683) on Asrock x99 OCF and Asus X99 Deluxe 2 the same processor and they go perfectly, but on X99 itx they do not go into bios!) and went well on other boards.
There is only one variable that a test ovi soon, because I bought other memories whose support is on the x99 itx motherboard
If it does not, it means that at this board, Asrock have bios problems, does not recognize the processor
and I bought the Xeon when their price was about $ 300-2683 and about $ 650-2696, now the price seems to be exaggerated.
Now it depends on what you do with them!
I have video renders and conversions, I can say that I am very pleased, it is at 1080 with 150fps, which is very strong, compared to normal processors that do not climb more than 100 fps
I also have a windows 10 made by .by.SmokieBlahBlah that goes tragically

 

[sciff]

agree !
1950x features:
$800 price
16 cores 3.9G
16 cores with SMT
REG ECC 2666 memory support
non-ECC memory DDR4 3000+
64 PCIE lanes

You can only use ECC UDIMMs (unbuffered/unregistered) with the Threadripper. This kind of modules are rare, expensive and their support would still depond on a particular motherboard.

Don't confuse this type or RAM with the sometimes cheap pulled out of servers and sold on eBay ECC RDIMMs (ECC Reg). However, even ECC RDIMM at 2666 MHz would be very expensive because it only appeared on the market recently and hence there's little chance of finding it as used anywhere.

No LR-DIMM support either.

I find it new, at 150 dollars the 1620 v3

Guys, I know it is a little off-topic here. But I am going to buy a dual-cpu motherboard. What's the probability that these two CPUs will not work together?

Spoiler: Intel Xeon E5-2696 v3 OEM and QS/ES both 2 stepping
