E5 2697 V2

Hi,

About the Xeon E5 2697 V2 - I've found a validator web page for CPU-Z where it shows other users who have overclocked this CPU. Please see link below

http://valid.x86.fr/top-cpu/496e7465...322e373047487a

Motherboards like the Asus X79 Deluxe & Rampage IV Extreme have been used as well as others.

Someone got an all core turbo of 3.4 Ghz (all cores) - with 30 x 113.97

Is it really this simple to get a multiplier above the standard 27 x 100 = 2700 Mhz

A good board would be needed but I've heard some tech journalists quoting it isn't possible to get above the standard multiplier.

I will try this when (and if) I can get hold of a CPU at an OK price which is always difficult for some of the higher end chips even if they are several years old!!!

I'd be able to alter the settings in the BIOS now I've got some OC's completed successfully but it was more me asking is this really possible for anyone without a BIOS mod. of some crazy work arounds.....Thanks

I suppose have a look on that site - Other users though have clocked the E5 1680 V2 to 4.2 Ghz and beyond as it's unlocked like the usual i7's

If you look at the CPU World data, the E5 2697 v2 can use the 35 multiplier when a single core is active.

http://www.cpu-world.com/CPUs/Xeon/I...2697%20v2.html

The top spot on the CPU Validator shows 1 core 2 threads so for that entry, the 35 multiplier is normal.

Positions 3 through 15 all show the 30 multiplier which is correct when 6 or more cores are active. Only result #2 shows 6 cores active and a 35 multiplier. I think if that entry was 100% legit, you would expect to see more CPUs on this list showing a higher multiplier.

CPU World confirms that this CPU does support Turbo Boost Technology 2.0. The higher than 27 multipliers are part of turbo boost. That does not mean the multiplier is unlocked. If it was fully or even partially unlocked, you would see more evidence of this on CPU-Z.

E5 2697 V2 in hand

Well, it's best to have it in the test bench! so now I can see the max. multiplier in the BIOS is 27 but when it's all fired up x30 is applicable somehow.

base clock 113 (112.98 x 30 = 3,389 Mhz) or there abouts - This is on the R IV E Black Edition which seems to only work on XMP OC at the best of times.

So I'm more than happy to have around 3.4 Ghz on all cores and now running in P95.

With this CPU the droop is pretty massive -which caused a blue screen on boot - OK, I've not set LLC so trying to cater for the droop with extra v-core.

So in the BIOS v-core @ 1.250_v but with the droop it goes to 1.200v_1.184_v_&_1.168v that is quite a big swing which caught me by surprise.

The v_core I wanted to go in with was 1.175_v to begin with just to see the lie of the land.

Two other CPU's had v-rise instead of droop - E5-1680_V2 & E5 2667 V2 - But E5 2667 V2 needed more v-core than 1680 which was another surprise.

Anyhow back to the 2697 v2 - It's looking good at 60c hottest core in P95 with possibility for lower temps if the v_core can be reduced but maintaining enough to avoid blue screen!!!

It looks like the system won't take v_core much lower than 1.168v - so 1.125_v is too low factoring in the droop.

The VRM's are hot and the DIMM slots near the I/O panel are HOT!!! - May try a spot fan to cool slightly but they'll still be hot

Any useful tips appreciated -

Well this is a weird one.

While back I read on ROG forums, one guys comments on OC'ing. "Your're overclocking now, sometimes you get to be Clint Eastwood or sometimes you get to be his dog" !!!.

I'll explain. For some reason early on in the OC I input 1.250_v in BIOS for v-core after a no start at 1.200v.

Quite quickly the OC becomes stable on R IV E Black Edition with XMP OC as on previous OC's the manual OC won't work on this board.

Then getting on with a stability test in P95 (or similar) I think to myself I can get the v-core down a fair bit more and get rid of some droop that caught me offguard which was as much as 0.075v so from 1.250v in BIOS it would droop to 1.168v at the lowest which I thought was the cause of a blue screen at 1.175v in BIOS which may have caused the v_core to go down to 1.125v or not far from that hence a crash on boot.

Anyway after attempting to alter load line calibration the system would not boot at all and trying to alter the previous 1.250v resulted in hours of wasted time and no result apart from 1.240v and no answer to the v-droop which also caused a v-rise on idle.

So after all this I just resulted to leaving the 1.250v although 1.240v did work. 1.230v did not boot even with LLC set to high.

The only parameter not altered was the v-core on boot in "digi-plus power" control which might have helped but maybe not on this board.

So the Xeon E5-2697_V2 seems pretty difficult to do much with !!! but 3.4 Ghz all core boost and a Passmark of 20,000 points seems to be a good result on this X79 platform and thankfully even though the 2697 v2 is a little pricey (£300) it's way under the initial asking price of $2,000 !!! so not too bad at all on R IV E !!!

hope 2697 price will fall a bit ,its nice to can have 12 cores in such old setup.

Well what I did was a Google search for the name of the processor and CPU-Z Validator, so, E5 2697 V2 CPU-Z Validator in Google.

It's a bit hit and miss
