The ebayed 4699s are often less than 2699s and they are 135w chips instead of 145w.Wow,
I lookup the price of each retail E5-4669 v4 is $5K, my down payment for my first house was $2.5K.
You should submit the result so you can be on that page! your benchmark fits right on with the other two 2683 v3 on there! looks like it narrowly beat the dual epyc 7601!What is the result I should be looking at? PI Calculation? I.e. my result is 220?
sure. download the y cruncher and crunch away... You should get some impressive time with that 44C system!ooou oou can I play?
I'll be rebuilding my rig soon, and will try that test on bare metal. Today I was running with my Desktop VM in the background (and 10 other VMs). I can estimate 10-15% performance increase.You should submit the result so you can be on that page! your benchmark fits right on with the other two 2683 v3 on there! looks like it narrowly beat the dual epyc 7601!
If you can wait a little bit - I can do that for sure. I'm getting new case tomorrow (according to UPS). Will start moving things into new enclosure later this week. During that time I wanna do a clean install of Windows and test some equipment that I have here. I'll be able to remove memory and run that test for you.TLN, if you got a chance and don't mind helping me out, much appreciated if you can test out the dual cpu with only 32GB ram or only 1 dimm per cpu and see what result you get for 5 billions digits. I am wondering if it's b/c I am running single channel that is limiting my time. thanks.
Fujitsu has some excellent documentation for their Primergy servers that is generally applicable to all systems using the same chipset and CPU architecture.My plan was to load it up with 8x 16GB RDIMMS it has 2x 16GB right now.
It was very disappointing to me that with dual cpu my 5 billion digit pi calculation actually run 5 -10 sec slower than with single cpu. I don't know why since cinebench scaled up accordingly going from single to dual cpu. so I am wondering if the single memory channel bottle neck is slowing it down since to calculate pi to 5 billion digits I have to use nearly all 32gb rams making the memory use being spanned over the single channel and QPI?
Independent Mode configurations
(https://sp.ts.fujitsu.com/dmsp/Publications/public/wp-haswell-ep-memory-performance-ww-en.pdf)This covers all the configurations that are neither in Performance Mode nor are redundant. There are no
restrictions apart from the "Don't mix" ruling for RDIMMs and LRDIMMs as well as for x4 and x8 RDIMMs.
Special attention is also given to configurations with less than four DIMMs per processor, i.e. less than the
minimum number that is required for Performance Mode configurations. The reason for such configurations
can be energy-saving considerations as well as a low amount of required memory capacity. Savings also
result from a minimization of the number of DIMMs. The quantitative assessment that follows below of how a
configuration of less than four memory channels impacts on system performance suggests the following
recommendations:
With regard to the LCC processor class (low-core count), operation with only one DIMM per
processor (minimum configuration) is not recommended. Operation with two or three DIMMs per
processor can on the other hand lead to balanced results as regards performance and energy
consumption.
In the HCC (high-core count) and MCC (medium-core count) processor classes, operation with one
or three DIMMs per processor is not recommended. Operation with two DIMMs per processor can on
the other hand lead to balanced results as regards performance and energy consumption.
The non-recommended configurations mean entire (1 DIMM per processor) or partial (3 DIMMs per
processor for the HCC and MCC processors) 1-way interleaving via the memory channels with the clear
performance disadvantage of up to 30%, as shown below, for the commercial application performance. The
special feature regarding three DIMMs with HCC and LCC processors results from the configuration with two
memory controllers over which three DIMMs cannot be equally distributed.
Is there any way to play DirectX12 games on 2008R2?ooou oou can I play?

It's not necessary channels, but memory bandwidth. And in that specific application: Easy to calculate, so you need as much mem bandwidth as possible.so seems like the number of memory channel can have very big impact
