You have the whole front panel that is perforated with vent holes. That's more than enough to provide proper intake.

If I had that case I would modified the front to allow mountable fan frame to have additional fans using spacers screws but that just my thinking of modifications

 

[KLiKzg]

Yeah I'm aware, but that's not the type of cooler I have
it would be pretty good.

I would be more concerned where is your CPU cooler fan blowing? To the back of the case, where it is the fan or to the front?

What it should is to blow to the fan in the back, as the fan in the back should blow out of the case.

No, I inverted it and it's blowing air to the front as well.

One dumb question: how do I make sure the unlock turbo boost worked proper?

Run a CPU stress test utility and use a clock monitor like Open Hardware Monitor or HWInfo to check the CPU clocks in real time.

And what kind of frequencies should I expect if it worked and if it didn't ?

 

[lexluthermiester]

It'll show you what your steady state turbo clocks are. Then you'll know if they're working properly.

 

[Nachmanowicz]

But I mean, whiat kind of numbers should I expect for each? lol

 

[lexluthermiester]

Remind us which Xeon you're currently using?

 

[Nachmanowicz]

A 2666 v3, sir

 

[lexluthermiester]

A 2666 v3, sir

Ah ok. So here's the official specs and that is what you should expect stock;

Intel® Xeon® Processor E5-2660 v3 (25M Cache, 2.60 GHz) - Product Specifications | Intel

Intel® Xeon® Processor E5-2660 v3 (25M Cache, 2.60 GHz) quick reference with specifications, features, and technologies.

www.intel.com

EDIT: Oops, it seems I copy/pasted the wrong link in. Intel doesn't seem to have an ARK page for the Xeon 2666V3.. Weird.

The all-core steady state turbo for that CPU is 2.9ghz. So if you can get the all-core turbo to stay locked at a faster speed, you know you've unlocked the clocks. That CPU isn't multiplier unlocked, so the best you can expect is to unlock the max all-core turbo and a bit of BCLK for it. For that CPU you should be able to squeeze 3.1ghz all-core and 104mhz, maybe 105mhz, out of the BCLK.

 

[Nachmanowicz]

Oh if I'm not mistaken they pretty steady at almost 3.5!

I did the bios mod myself , with a 50 60 undervolt (whatever that means) and then on the BIOS I disabled 2 cores making it an 8/16 CPU.

 

[lexluthermiester]

How do you get it that fast without changing the multiplier?

Undervolting is the terminology of decreasing voltage to the cpu = reducing temperature = reducing power at a small minitule scale

Oh i know that, what I don't know is what the 50 60 are. Specially since it's two different numbers....

I didn't do anything. Only changed the BIOs and there it was. I don't have that computer with me atm, I lent it to a friend of mine that is considering buying a computer for emulation. Should get it back in a week.

Seems he figured a way by disabling two cores in order to go higher clocks via bclk I'm guessing as you think about it more cores/threads are enabled on that cpu it have yielded less clocks is shown but with two disabled cores it went higher in clocks seems like a pretty good idea to overcome the limitation of the cpu in question.
Undermillivolt could be 0.050v or 0.500v depending on the bios/board some may not have alot of range to tinker with due to the limitation of a Chinese board or barebone board is what I am thinking possibly but could be wrong on that

 

[lexluthermiester]

I was wondering about that. Seems plausible.

 

[Nachmanowicz]

I didn't change the bclk. I barely fiddled with the BIOs tbh. I spent only like 4 days with that computer after I put it together.

I changed the BIOs by doing it myself after watching a video tutorial. It was real weird but also quite easy to do. THe only part I had any real agency was in the undervolt part. He said to go for 50/50 undervolt cause it works pretty much all the timem ,but you might go lower under the risk of instability so I went for 50 60. So far no problems, my friend also didn't report no BSODs or anything.

I'm confused...

 

[Nachmanowicz]

I'm confused...

About what exactly?

I did it based on this video:

It's in portuguese, but there's actually a LOT of Xeon content in portuguese due to the ease of importing stuff from China to Brazil compared to from other countries and their price.

 

[:D:D]

@lexluthermiester it's a 2666v3 not 2660v3 as you showed!

Intel Xeon E5-2666 v3 Specs

Haswell-EP, 10 Cores, 20 Threads, 2.9 GHz, 135 W

www.techpowerup.com

For best results both core and cache are undervolted, hence -50 -60 millivolt offsets.

IMO V3 was actually quite interesting in the way it handled core load without depending on RAPL.

Yes, it's a 2666 v3!

Oops! Sorry about that. Yup, that changes things a bit.

If Unlock Turbo Boost enables all cores to the max Turbo then I guess it worked. Can I try to go even higher???

Yes, with a BCLK OC. Seems you're running stock(100mhz) if 3.5ghz is what you're getting. You might get the BCLK to 104 or maybe 105, which would result in a bit more of a boost. 105 x 35 = 3675.
