The statement you made about having 32TB of RAM is again, partially true. But NONE of the single OS instances EVER have full control of all 32TB at once, which again, by DEFINITION, means that it is NOT truly SMP. (Course, if you ever get a screenshot which shows that, I'd LOVE to see it. I'd LOVE to get corrected on that.)" 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.
Firstly I would like to say a big thank you to GIGABYTE Server for the opportunity to test these CPUs in their motherboard, the GA-6PXSV3. This motherboard is the focus of a review at a later date. Like I said, most of the numbers that you wrote are true, but the assumptions behind them isn't exactly all entirely true. What ever board you are using ---google it for OC'ing and you may find ROG Asus posts for other people gone before mentioning BIOS tweaks......... 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)."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. Virtual machine speed-up technologies supported by Xeon E5-2697 v2 and Xeon E5-2695 v2 are enumerated here. VT-d Technological solutions and additional instructions supported by Xeon E5-4657L v2 and Xeon E5-2697 v2. You'll probably need this information if you require some particular technology. Instruction set extensions First of all thank you for your time reading this post and I hope so that you will enjoy in content bellow..... The nearest equivalent of the Core i7-4960X in the enterprise lineup is the Xeon E5-1660 V2. In terms of my testing at AnandTech, the i7-4960X represents the standard enthusiast processor that blitzes our benchmarks, and thus an opportunity to test something potentially faster is always welcome.
It'll be interesting to see what IBM does with their next generation of hardware as the GX bux is disappearing. At the ultra-high-end of any CPU range, we can see a fight for cores against MHz to remain within the thermal design power limitations. Users can spend their money on more cores, which benefits parallel computation, or focus purely on MHz for single-threaded throughput. The downside of moving to higher MHz is usually efficiency, so the gains might not be as linear as expected. Types, maximum amount and channel quantity of RAM supported by Xeon E5-2697 v2 and Xeon E5-1620 v2. Intel’s roadmap goes through all the power and market segments, from ultra-low-power, smartphones, tablets, notebooks, desktops, mainstream desktops, enthusiast desktops and enterprise. Enterprise differs from the rest of the market, requiring absolute stability, uptime and support should anything go wrong. High-end enterprise CPUs are therefore expensive, and because buyers are willing to pay top dollar for the best, Intel can push core counts, frequency and thus price much higher than in the consumer space. Today we look at two CPUs from this segment – the twelve core Xeon E5-2697 v2 and the eight core Xeon E5-2687W 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.Unless in the future I experiment how much more etc......performance can be had.....but not for now
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. 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.
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.
Great Deal
