Intel Xeon E5-2686 V3 QS QG7V 18 Core 36 Thread 45mb L3 120w 3.5Ghz Turbo CPU $750 OBO

This CPU is the PERFECT balance between power consumption and performance and is RARE to find as it is the QS (qualification sample) and has identical stepping (C0) and functionality as the OEM/retail version

This CPU was used lightly and rarely had higher than 10% utilization. Ran for a few hours a day (not 24 hours/day)


It uses 25W lower power consumption than all of the other 18 core E5 v3/v4processors (except for the E5-2695 V4) and costs less!!

The E5-2695 V4 is closest in clock speed/turbo speed/TDP to this CPU, but it is more expensive and has a 200MHz lower turbo!!





Pulled from service, tested and guaranteed 100% working with no stability issues, and placed into storage

Photos and benchmarks are of actual item, your benchmark results may vary depending on your configuration

Supports virtualization when enabled in BIOS and tested with VMs

This is a QS (qualification sample) processor and has identical stepping (C0) and functionality as the OEM/retail version

Thoroughly tested with an Asrock X99 Fatality X99m and Supermicro X10SRA-F and works great

You're missing a transistor in the lower left hand corner (2nd pic). I've run several chips this way long term with no ill effect.

What is your CB score with these? Turbo bins are worth noting..

Thanks for noticing the transistor, I never really noticed it before you pointed it out. Haven't had any problems with the CPU at all.

2098 Cinebench, of course this will be different based on your configuration.

Uhm. Thats not a transistor guys. Its a capacitor. And its used for smoothing out the core power. All SKUs have the same population, so lower power cpus will have same as higher power cpus. So the missing cap will not affect the performance or stability of the cpu. There are lots of caps and also lots of caps on the motherboard doing the same thing.

Good catch... not sure where I pulled transistor from. Last time I spent any time on it was here:

The chip here can all core turbo to 3.5, one of the best v3 chips.

The chip here can all core turbo to 3.5.

Are you sure its all core turbo?

 

[AJXCR]

Are you sure its all core turbo?

I'm a little curious about this as well.. I've seen this mentioned in numerous places, but also have seen reports (even on STH) that users were unable to achieve these results.

OP: Any chance you would be willing to demonstrate this?

 

[AJXCR]

According to this STH thread, 2.3GHz ACT

FS: E5-2686 V3 QS/ES 18 Core CPU & 64GB DDR4 ECC

Maybe this is the cause for some of the higher ACT clock speeds being reported?

I have 2x QG7V. The all core is 2.3. The turboboost bios mod can get it up to 2.8ghz all-core in a dual socket config for ~20% gain in cinebench. It is a great chip, good boost clock and decent all core. I got mine before a bit over a year ago for about half that, before people saw the value. The price seems high, they go for ~600 imo. If one can get 750 that out of them, I'd sell both of mine and buy an i9 and consolidate threads. For price, a 1920x (or a 1950x on sale) would give higher single and all core performance with ecc support available on boards.

I have a S2600WTT server with 2 x E5-2690 v3 ES. If i remember correctly, after the bios mod the chips all core turboed (12 cores 2x)to 3.4 or 3.5 without a problem, not even heating up that much. Now i have them sitting in a supermicro server board which i wanted to build a workstation with but something is up with the fanspeed, i can't get it to turn down (no mods).

The chips are fairly rare, as they are ES processors with the production code QFRX, not QGNY, which is more common and a QS. Maybe there is a diffrence between the ES chips and the production chips in terms of limits.

I am wondering whether the 2690v3 would beat the 2686v3 ^^.

Don’t be an ass. This bios sounds too good to be true. Post a screenshot of all the cores boosting to 3.5ghz?

Why do you assume i am being an ass? I don't really want to defend my position, do some research if you want to know more about it though.

What controls Turbo Core in Xeons?

Although I doubt all cores up to 3.5, it is probably close for that chip. The 2696v3 with this mod is ridiculous. There are Benchmark results in that thread and I believe that there are some for that chip.
