I've lost track... what is the fastest stock ivy xeon with more than 8 cores I can run on x79?

 

[johnspack]

Wonder if it's possible to push the 12 core to over 4ghz....

Those CPU are locked and only way to OC them is via BCLK and for that you gonna need some decent branded X79 motherboard....I have Xeon 2697V2 12c/24t and I managed to rise BCLK all the way up to the 115,1 which gives me 3,45Ghz on All cores + Turbo up to the 4,03Ghz(few cores) but I assume that this probably maximum OC or near to the absolute Maximum you can do with the BCLK OC
Also you can read about my testing and OC via BCLK == HERE

Only with very good liquid cooling. 240mm rad or better per cpu.

Aren't the E7-2850v2's unlocked?

 

[johnspack]

My mobo isn't a pussy... it'll do some sh**.... but just noticed prices on that... under 150can... seems very doable.
I'm more interested in vms and stuff like that now anyways... I don't really need over 4ghz... a bit of an oc should do.
Some day... threadripper. For now... I have to use this junk....

No actually nothing to do with the cooling.... it's just a fact that you need to rise the base clock and that can give you that much before it's starts dropping on you....in fact do not expect even 110 on BCLK people usually OC around 103-107 anything above that is excellent.......
Those are E7 I assume those are also locked and as I am aware they can't work on X79/regular motherboards

Board doesn't matter when the chip is locked. You want an unlocked 8 core? 1680v2. Anything bigger is bclk overclocking.

X79 also isn't junk. Still very much strong enough to do just about anything today.

 

[johnspack]

Already run the 1680 v2. But I need moar cores! So hope I don't regret this:

Should've probably done with a dual socket at this point since you're using virtual machines. Plenty of ATX/E-ATX dual sockets with eight DIMM slots on that family. Honestly I'm sure a second 2697v2 in one of those boards would be great.

 

[johnspack]

I would like a dualie mobo... I might have to think about that when I get more funds. On my fixed income I could barely afford this thing.
I am going to try some blck ocing on this thing when I get it.... probably won't get much, but should be fun. Eventually I could get the dualie
and add a 2nd 2697, and keep the 1680 in this mobo.

 

[Toothless]

Just don't expect a whole lot of overclocking on the 26xx chips. I know Supermicro and Asus have some nice little dual socket boards.

I think you'll be happy with it. With the board you've got, you should be able to OC and get 3.6ghz all-core without much fuss. Scratch that, just remembered that CPU is not unlocked. Still, there should be a BIOS option for forcing the highest per-core-multi to all cores.

 

[johnspack]

I've seen it can do 3.45 all core with a bit of tweaking. But some have got it to 4ghz. My mobo probably won't do it... but I'll probably try.

4Ghz it's impossible...that's only turbo boosting on few cores....also PCIe on high BCLK OC become sensitive and it will probably work only like PCIe 2 but honestly that is not a big issue IF everything else working find and your machine is stable....GL

 

[johnspack]

I believe I can lock my pci-e freq in bios.... 101 is usually best. I'll have to reboot to bios to confirm, but I believe that's what you do
for blck ocing.....
Even if not... every day I keep saying while trying to do things with my vms.... I wish I had more cores..... I wish I had more cores.....
This is all I can do until I can afford a threadripper.....

Doubt that...you can use strap but problem with those Xeons is that they working only on first strap(100Mhz)and then you can rise the bclk....never the less here my last CPU-Z run bellow in attachment...
P.S.The positive thing IF you managed to OC this Xeon you will not need to add much V usually you easily can stay bellow 1,2V(my working on 1,17V)so there is no problem with cooling at all....they are cool...

 

[johnspack]

Well... I need to test it. A bird in hand is worth 2 in the bush. I'll still have my 1680 cpu, so nothing lost really. And 8 cores just sucks for doing things for what I do. Screw gaming, I got bored
with it. Vms and rendering are much more fun for me now. And I get to play with a new cpu! Win win.

 

[Mr.Scott]

Much more PCIe for bclk OC'ing. 105-115 pending how much bclk you're trying to get to.
This from a benchmarking aspect of course, not 24/7.

Well...not really I mean at least not for me....I did detail testing and my RIG working 24/7 on 115,1 on BCLK never have any issues it's 100% stable...the thing is that I can rise the BCLK a bit more but then the system is not stable anymore....I honestly do not like to show my scores&benchmarks IF I can't use my system 24/7 on that speed I don't see the point in that.....

Been playing around with the Intel C-State Tech in the bios while running the 4.20ghz overclock. Since it been enabled I did observe the behavior that it lowers the vcore, power and current when it in idle state. I rang TT Isle of Man 2 as it the only game that seems to crashes randomly during the race while the C-State been enabled so I figured out a way around the crashing issue by going into processor power management and setting the maximum processor state from 100% to 95% which on the fly it changes the overclock from 4.20ghz to 4ghz without restarting the system or going into the bios. When the game is running I was checking the actual vcore reading it bouncing about from 1.192v to 1,232v depending on the cpu load but most of the time it hoovering about 1,208v without crashing the game

I've lost track... what is the fastest stock ivy xeon with more than 8 cores I can run on x79?

E5-2697V2 (12C/24T) followed by E5-2690v2 (10C/20T) . Both are locked. Stuck with stressing components using BLCK OC. Requires a very good motherboard to do this effectively.
Best high core unlocked is the venerable E5-1680v2 (8C/16T). Decent OCing on a good motherboard.

 

[johnspack]

I may be able to get some financial help with a dualie mobo and a 2nd 2697... probably my best option for the next few years.
Lots of mobos on ebay for around 100us... but can't figure out what's best. I eventually want a 2nd case, psu and ram to run both
this 1680 and a dual 2697 server system. And then some day a threadripper.... but thats just a dream...

You'll want an actual server board. Not these Chinese boards that are salvaged together.

If only your budget was higher, I'd sell you my board and ram.

Why? I run one as a daily driver and it runs perfectly. X79 with an E5-2667v2 and 32GB of 1866ECCreg. It's been great.
