Message 1871690 - Posted: 8 Jun 2017, 4:04:13 UTC

So I have almost finished building my system, need to get more RAM to fill the 16 slots I have, and more hard drives + SSD, so what is the expected runtime of each task?
Here is my PC
I have run a few units, but I need a baseline from someone else to compare.
Is having only 2 of 16 slots filled for RAM hampering apps currently

16GB is lots for BOINC, but depending on what else you run ...... Just watch what you have free.

The E5-2670 CPU works best when using all 4 channels of the 4 channel memory interface. So for 2 CPUs you would be looking at a minimum of 8 dimms for best performance.
Right now with my dual E5-2670 system I am only running with eight 8GB dimms, for a total of 64GB, Even though I do have sixteen 8GB dimms to put in it. My main reason for that is I do not currently need 128GB in the system. So removing half the RAM saves power usage.

With turbo keeping my CPUs running at 3.0GHz task run times are ~2-2.5hrs for 32 at a time.

Thanks for the baseline.
I see.... the last few tasks that ran had over 9 hrs on runtime....
I have populated 2 of the 16 dimm slots on my motherboard....

Check the CPU clock speed and temperatures.

My C2D can turn out work faster than that when most of it's CPU time is devoted to keeping the GPUs busy, and since that CPU supports AVX, it should be much faster than my C2D even though it's running at a similar clock speed once it starts using the AVX application.

The cpu is running at 2999 mhz which is essentially 3 ghz, and its running at 52C and hwmonitor tells me that the CPU is being used completely, so I think its because my only pair of memory is on socket 1

passmark is giving my PC 11k instead of the usual 18k, so I really think I just need to fill the 16 slots of memory completely

I might be beating a dead horse here but did you also switch to the maximum speed power plan (100% at idle) as will as confirming your turbo boost is turned on in the bios? You might also confirm that turning off any kind of "speed step" or "rest states" in your bios might speed things up? As well as setting the power plan to "never sleep"?

I just was reminded about the speed step issue(s).... :(

I just looked and your still running extremely high clock times for your Seti tasks. I think even one more same sized/speed memory stick in the appropriate slot would speed life up.

Unfortunately this motherboard only accepts memory in pairs, so I must buy 2 sticks to do that, but I have a A$500 solution ready in hand

Only having RAM for 1 CPU when there are 2 CPUs there would cause a big performance hit, but I wouldn't have thought it to be as huge as it is. It will be interesting to see what adding another 2 Modules to the other CPU does.
I'd also expect the temperature with all threads processing at full clock speed to be much higher.
Are you running after market coolers? What's the ambient temperature?

Or at least just 2 slots for each CPU (4 DIMMS) would allow Dual channel operation, or 4 slots for each CPU (8 DIMMs) to allow Quad channel operation.. No need to fill all 16 for Seti work. The motherboard owner's manual should show you which slots to use for best operation with only 4 or 8 DIMMs.

I am running Hyper 212x. I am going to try moving 1 of the dimms to the other socket, but I think my motherboard will scream at me for not having paired memory

Room temperature is currently.... 10C most of the day, however its "space heater" function isn't being achieved yet..... I am cold

Yeah, that would keep even a hot CPU cool when fitted correctly.

A quick look (at what appears to be the right manual) shows that 1 Module is OK per CPU. You need to make sure you use a blue slot. It doesn't specify a particular slot, but usually it's slot 1 or A or the slot closest to the CPU (in this case the closest blue slot). Given the 2 banks for each CPU, you might have to try both banks.
I'm surprised the system booted up ok with memory only for one CPU.

Certainly, 1 Module in each bank for each CPU would be much, much better. As to how much better 2 modules per bank would be, I couldn't begin to guess. For Seti having all slots filled wouldn't be any better than 2 modules per bank per CPU.

From looking at the manual, with the ATX power sockets at the top right hand corner, a memory module in the blue slot closest to the CPU (both the LH & RH CPU) should work.

In the UEFI under Memory settings, the memory mode would most likely have to be Independent.

It just occurred to me this morning, that until you have enough ram to run the MB/Cpu's(?) properly, you could use the preference's for the amount of cpu you are using with BOINC to cut it down to say 4 cpus. This would give you faster production (probably) till more of the ram shows up to be installed.

So I think I have completed the memory move, and now it is accepting 1 module per socket I think....
Lets see if there is a speed up...

What Hal said about populating all 4 channels has me thinking if my i7-3930K would be the same currently have 4x4GB installed, I have 4 more new ones I have never used/tried. I'm not having luck finding info, and Intel's Gen3 datasheet is unavailable, grrr.

The OS certainly doesn't need it with 2.5 of 16GB used, but does the CPU want it, hmmm .......

An update, by moving memory to the other socket my passmark score went from 11.8k to 12.7k, so a minor improvement. But an improvement nonetheless

I had a 3930K and a pair of mobo's (ASUS WS and similar). There was a recommended order of populating the RAM slots. If you can enable the BIOS option saying 'two channel' or something you may have the correct settings and placings for the RAM modules. I was able to run 1T but only when the modules were in the right places. Otherwise it needed 2T.
