Hardware projects / How to use a 4k TV as a computer monitor
« Last post by Andy Brown on Yesterday at 11:50:01 am »
I just posted a new article that documents my experience using a 4k TV as a computer monitor. I walk through the selection process documenting all the pitfalls that I found along the way. Hopefully if any of you are considering doing the same then this will help you make your decisions.

Hardware projects / Frequency counter using FPGA
« Last post by wafaem on March 22, 2019, 10:03:55 am »
Hello everyone,

I'm currently working on a project that aims to build a frequency counter(reciprocal one);but since I don't come from an electronic background I really don't know how and what to do.
My aim in this project is the frequency since the signal is very fast, I'm using nexys 3, if anyone has an idea or worked before on this I will appreciate it.
thnk you

Hardware projects / Re: Hacking an HP Z800 motherboard into a standard PC case
« Last post by gio321 on March 13, 2019, 04:49:02 am »
First of all, many thanks to Andy and everyone here for the great tips that helped me build my own hacked Z800 based machine.

It's housed in a Nanoxia Deep Silence 5 and it's happily running 2 x x5680's with the 003 M/B.

Corsair H55 AIO liquid coolers fit perfectly without any mods.
I got 2 Corsair factory refurbished ones for £35 each (for the UK based people) and they are running fine.

The PSU is the COOLERMASTER SILENT PRO 1000W and I made my own memory and M/B cables by following Andy's and b1Ack's instructions (a few posts above) and did not connect the +5V pins on the 18pin cable. It's running fine with 48GB of RAM.

I'm running a Mojave osx based Hackintosh system with 2 x PCIe NVME drives and 9 x HDDs all working fine both on Intel and the SAS controller (plenty of drives in apple soft raid config as I'm using it as a music studio workstation).
Graphics is the Sapphire Pulse RX580 8GB and I also got a USB 3.0 PCIe card.

Again thanks all.

Hello.
I'm stuck with programming new SPI with Andy's flash bios.bin from 003 board.
Can You guide me through this.
I placed the chip on CH341, programmm detects it. Then I open Andy's bios, erase the chip, and then I press program/write.
But after 10-15 seconds I get error write timeout.
What could be the problem?

Regards
Gorazd

CPU Cooler alternative for HP Z800.
LC-Power's LC-CC-120-LiCo Liquid cooling fits like a glove on original CPU heatsink nuts.
https://www.lc-power.com/en/product/cpu-cooler/lc-cc-120-lico/
Same goes for normal Air cooling LC-CC-120.
https://www.lc-power.com/en/product/cpu-cooler/lc-cc-120/
Using It's standofs for AMD fit and 3mm washer on top, then using bracket for Intel 115x, It works perfectly.
Combinig standofs from LC-CC-120-LiCo and everything else from LC-CC-120, I got this...
Temperature droped from 47C (stock cooler) to 34C (LC-CC-120) in idle, and from 59C (stock cooler) to 48C (LC-CC-120) under full load...
Running 2x Xeon E5520.
Next step, BIOS chip change (rev 001 BootBlock to 003 BootBlock) for 2x E5645.

How update bootblock ?
I'm surprised that lot of people was looking for right rev.003 full image, not looking what we have - a /B option for DOS flasher. Just used it and my bootblock became a new one with 2018 BIOS version in some time. And - process look really long and looks like it hang. For more than minute. No progress, no numlock reaction - nothing. Don't panic, read what you have on screen, all fine, obey and go make some tea and not look on this f***ing thing - and it will end and be ok.



No luck for me.
BootBlock remains 01/30/09.
What CMD line must I use to upgrade bootblock with flashbin.exe?  :-\ :-\

What did you do with the rest of the parts, Nitto? Are you selling them? You're going to love the SSD btw, such a performance booster.
