RN3220 CPU upgrade -- Negligible effect??
I upgraded the processor of an RN3220 from an i3-3220 3.30GHz, which is dual-core 4-thread CPU, to a Xeon E3-1225 V2 @ 3.20GHz, a quad-core 4-thread CPU as comes in an RN4220 and sysbench shows almo...
OK, I'm not entirely sure what was going on. I upgraded a second one and got way better results. So I swapped the memory between the two and the first one now gave me the improved speed. Just to check, I swapped the memory back, and now they both perform like this:
Test execution summary:
total time: 2.5567s
total number of events: 10000
total time taken by event execution: 20.4385
per-request statistics:
min: 1.02ms
avg: 2.04ms
max: 28.60ms
approx. 95 percentile: 11.02msThreads fairness:
events (avg/stddev): 1250.0000/27.44
execution time (avg/stddev): 2.5548/0.00So, the memory must not have been seated well, even though dmidecode showed both banks properly. Since I swapped out the memory before the CPU, I suspect that the performance shown for the original processor is also bogus.
What Video card did you use? , were all drive bays populated? I have one that seems to have been taken out by a power surge, any suggestions would help, Thanks
I used a Zotac GT710 Zone Edition PCIE=X1 (yes X1) card which is a low profile card. It only requires a single slot unless you want the VGA connector. The VGA uses a separate slot but is connected via a cable. But they are hard to come by. It's also available in a X16 form factor, so be sure you get the right one. And be sure you get the low-profile bracket(s).
Zotac also made a fewer older ones that are similar form factor and ought to work. Several companies made GT210 based PCIE-X1 cards. The problem with most is getting the low-profile bracket. But if it's just for troubleshooting, you could go without a bracket.
MSI makes a similar card in a X8 format that I suspect would also work, but I've not tried it.
Thank you, I will try to get one of those, I tried a pcix-4 card that had no pins beyond the connecter - did not work
