Both options were disabled. The inbuilt help says that NUMA should be enabled for Windows and disabled for Linux, so I enabled it since I'm using Windows 10. That seemed to slightly slow down the benchmarks so I'll be disabling it again.

Thanks Andy. Almost a copy from my most recent results. Do you have MNI or NUMA enabled?

I've attached my results. They are broadly the same as you describe for yours.

After i got my ram errors away i have done few memory benchmarks to see what could be best BIOS settings for my combined workstation and gaming. I am using MaxxMem2. Read speeds seems to always be almost 13gb/s but copy and write always stays way below 10gb/s. And latency varies from 80ns to 150ns. Maximum total speed always under 10gb/s. I would like to see more benchmark results from other z800s to compare. Friend of mine running z400 with x5687 triple channel 1333mhz got MaxxMem total result of 13gb/s. I know these two system are a bit different but still got me thinking is there something wrong with my z800.

Just an idea: Should we open new thread for combined benchmark results? Cinebench, 3dMark, PassMark, etc?

Hardware projects / Xmemtft Ili9325 180 degree rotation
« Last post by laughingguffly on February 19, 2017, 03:18:00 pm »
Firstly, very impressed with the speed of Xmemtft. By far the best library I've come across..

I'm trying to rotate my display 180 degrees from Portrait.

How do I go about doing this?

I've tried setting ili9325::ILI932X_ENTRY_MOD(0x03) to 0x1000.

Is there a simple software switch I am missing or do I have to use the moveto function? I've tried following the Adafruit TFT library which handles it fine but can't get it going. The text appears fuzzy and that's as far as I could get.

Any pointers?

Thanks

Good evening.

Some more chat with the seller and few new ideas and now everything seems to be working. He said the problem sounded very similar to what he had with a z400. During transportation something could slighty move out of place and he told me to reinstall cpus. I also swapped them to see if the problem is in the memory controller. So after some cleaning and reinstalling all memory modules are now recognized and triple channel working fine.

I still have to troubleshoot the warnings, but press F1 and ok.
I never bothered eliminating them and to this day I'm still pressing F1 on startup!

The usb and 1394 dont is critical, but the fan error i need solve. I'm doing reengineering in the fan conector, i already buy the male connector in digykey, end of the month should be coming.

https://www.amazon.com/Z820-Chassis-Power-Supply-642163-003/dp/B018WRL6I2/ref=sr_1_2?ie=UTF8&qid=1487253780&sr=8-2&keywords=z820+power

hoping 850 will cover 2x2670/ram and single 1080.
cheers.


I bought at mercadolivre.com a brazilian auction site. I was lucky because I bought when I posted that first message and there were no chinese cables, so the power supply dont sell well. The seller was a year advertising and lowered the price for me buy.
Who does not buy the cabinet, i recommend getting a Z420 motherboard is ATX size dont need case mod. The Z820 need case mod and has serious heat problems, the memories fry! I had to buy nine 12cm fans to put on the sides of the cabinet, plus two 14cm inside and one 8cm fan to blow air into the power supply. Not counting the two hyper 212s for the cpus.
