Types, maximum amount and channel quantity of RAM supported by Xeon E5-2697 v2 and Xeon E5-1620 v2. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See http://www.intel.com/content/www/us/en/processors/processor-numbers.html for details. Unfortunately anything over 6-core loading reduces it down to that lower 3.0 GHz mark, whereas single threaded speed is up at 3.5 GHz. Ultimately it is up to the motherboard to implement which turbo modes and P states are in use, and on the consumer line we often find motherboards using a form of ‘MultiCore Turbo’ (read our explanation here). If the E5-2697 v2 was put in this position, we would have 12 cores at 3.5 GHz, ready to blast through the workload.

Unless in the future I experiment how much more etc......performance can be had.....but not for now The E5-2643 v2 has the most L3 Cache per core of any CPU, at 4.16 MB/core. This is a 10c die offering all 25 MB of L3 cache, but only six cores are active. Reasons for this include database applications that need a large amount of L3 cache per core. For licensing agreements that hinge on per-core pricing, having a larger amount of L3 per core could help save some money by needing fewer cores.

The former is also the 12-core representative in the late 2013 Mac Pro, whereas the latter is the highest TDP processor that Intel makes in this segment. A few other CPUs share this honor, although they are part of the Ivy Bridge-EX E7-x8xx line. My goal was to find out where these two CPUs stand in what I consider ‘an enthusiast user’s scenario’, and as such we used the same benchmarks as in the AMD Kaveri launch article, involving gaming, compression, rendering, video conversion and 2D image to 3D modeling creation. Johan has dealt extensively on the enterprise server and high performance computing aspect of similar CPUs, and his deep dive into the functionality is worth a read if you have not already seen it.

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.

As pointed out numerous times before, that link is you cite is a decade old. SGI has moved into the SMP space with the Altix UV series. Continuing to use this link as relevant is plain disingenuous and deceptive. Types, maximum amount and channel quantity of RAM supported by Xeon E5-2697 v2 and Xeon E5-2695 v2. Types, maximum amount and channel quantity of RAM supported by Xeon E5-4657L v2 and Xeon E5-2697 v2. 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.It'll be interesting to see what IBM does with their next generation of hardware as the GX bux is disappearing. I don't know what board you are on ------but if it is a good Asus board.......with the BIOS......(MSI may do this I don't know). Kevin G - Wednesday, March 19, 2014 - link "That means that it is a monolithic system, again, of which, few are TRULY such systems. If you've ever ACTUALLY witnessed the startup/bootup sequence of an ACTUAL IBM mainframe, the rest of the "nodes" are actually booted up typically by PXE or something very similiar to that, and then the "node" is ennumerated into the resource pool. But, for all other intents and purposes, they are semi-independent, standalone systems, because SMP systems do NOT have the capability to pass messages and/or memory calls (reads/writes/requests) without some kind of a transport layer (for example MPI)." Single processor LGA2011 Xeons are under the title of E5-16xx v2. Dual processor system capable Xeons are E5-26xx v2, and quad processor system capable Xeons are E5-46xx v2. As Johan pointed out in his excellent dive into the improvements over the older architecture , these CPUs come from three die flavors: So there's the two problems with this - 1) it's SGI - so of course they're going to promote what they ARE capable of vs. what they don't WANT to be capable of. 2) Given the SGI-biased statements, this, again, isn't EXACTLY ENTIRELY true either.

Not exactly. IBM's recent boxes don't boot themselves. Each box has a service processor that initializes the main CPU's and determines if there are any additional boxes connected via external GX links. If it finds external boxes, some negotiation is done to join them into one large coherent system before an attempt to load an OS is made. This is all done in hardware/firmware. Adding/removing these boxes can be done but there are rules to follow to prevent data loss. In a SMP server, all cpus will have to be connected to each other, for this SGI UV2000 with 32.768 cpus, you would need (n²) 540 million (half a billion) threads connecting each cpu.

A cluster is made up of SMP compute nodes but each node cannot communicate with each other so scaling is limited to a single compute node...." With the greatest performance possible combined with the best temps possible ---- and when one goes out of the Window (usuallly temps)___that is OC finished.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.
