Hardware info, tips & tricks / Black and White Ryzen build
« on: 10 June, 2017, 06:01:23 PM »
My dad wants a new PC. I'm going to give him my son's rig (7700k) and give my son this rig.
He went back to do the funeral for my grandpa, so I'll have a few weeks to abuse this 7700k a little bit :) before pass it on to him.

New rig:
Mobo: MSI B350 Tomahawk Artic
CPU: R7 1700
Dram: Flare X 3200mhz
Case: Phanteks Eclipse P400S white
PSU: Seasonic 650w
GPU: old R380
Cooling: Corsair H110i 280mm
HDD: some cheap ssd I still have at the house.
Total damage: $935 ($250 cheaper than what I paid for the 7700k build)

All parts ordered from Neweggs. They came alright except for the case has a little dent on the top.
I was a little upset but I can live with that. Doesn't want to go to the RMA process.

Here's what I did to get my memory to run 3200mhz on the Tomahawk:
At the very first boot, I checked the Bios version and the board came with Bios version H10.
Current official version is H40 as the time of this post. So I set the correct time/date etc etc .. basicly all default then save and reboot.
Then I download the H40 bios on another computer and copied it to a usb. Flashed it then went back to the bios.
At this time, my memory is running at 2400mhz by default. Then I proceeded to install Win10(download the latest version using window media creator).
After windows installed and updated, I downloaded the latest chipset driver from AMD and installed it.
Ok it's time to see if it will boot with memory running at 3200mhz, so back to bios again.
Here I leave everything on default, I only change these things:
 - OC mode from normal to expert
 -Dram speed from Auto to 3200mhz
 -Memory Advance: Auto to 14-14-14-34
 -Memory voltage: 1.36v
 -AMD Cool N Quiet : Disable
Saved and reboot .. and Bam .. it booted.  \^/  1 try lol
Do not touch Game Boost , A-xmp , Try it mem(or something like that can't remember exactly). Just leave them on default.

Went back to bios again to OC cpu. This time I only changed the cpu frequencies to 3725mhz. Left vcore on Auto.
Booted back to windows with no issue. Downloaded Boinc and let it run WCG until now.
CPU temp is 51C under load  :character0029: but VRM temp is 77C  :41:
CPUz showed vcore is 1.2v.
I haven't check power draw and stuff, it was almost 3am and I have to work today.
I'll take some picture and run some benchmark later tonight or tomorrow.
All and all this build went pretty smooth except for that little dent on the case.

Linux / Reference: Linux Mint 18 installer crash (dual boot)
« on: 05 April, 2017, 02:32:28 PM »
"We're sorry; the installer crashed. After you close this window, we'll allow you to file a bug report using the integrated bug reporting tool. This will gather information about your system and your installation process. The details will be sent to our bug tracker and a developer will attend to the problem as soon as possible."

I tried to make one of my box dual boot (Mint 18 and win 10), but kept on getting the error as above.
I've re download the ISO, tried 7 different usb. It doesn't matter, still getting the error.
Made sure that I was in UEFI mode, disable secure boot .. still getting the error.
I was very frustrated at this point, almost decided to wipe out win 10 and just do a clean install.
Then I stumbled on a post said something about boot into windows then do a complete SHUT DOWN and
disconnect the internet. Then try to install again.
The complete shut down trick didn't work. But the disconnect internet trick did.  (^
If you know any other trick, feel free to add to this post for references /=\

Hardware info, tips & tricks / Ryzen 7 1700 PPW comparison
« on: 16 March, 2017, 01:55:34 AM »
Ok, I had the Ryzen 7 1700 only about 3 days of running on Windows 10 Pro.
I'll do a quick comparison  PPW between the 1700 and my dual E5-2695 es V4.
While these numbers may not 100% correct but I think it should be close.
Need to run like a month or something to get the perfect numbers.
Anyway, I'll pick the points for today 3/15/2017 on both machines:

1700 (16 threads) @ 3.7ghz = 165W
WCG points = 71,655
PPW = 71,655/165 = 434 wcg ppw or 62 boinc ppw

Dual E5-2695 ES V4 (56 threads) @ 2.8ghz = 305W
WCG points = 235,038
PPW = 235,038/305 = 770 wcg ppw or 110 boinc ppw

Note : Both systems are running FAAH but the 2P is running Linux mint and the 1700 is running windows 10.
I'll finish up the cache WUs then I'll install Ubuntu and compare again... Linux to Linux.
If any1 is running a single xeon V4, please post your numbers to compare with the Ryzen.
Ryzen 7 1700X and Ryzen 7 1800X's owners are also welcome  {{{}

World community grid / FAQs for WCG
« on: 17 February, 2017, 11:58:58 PM »
- What's WCG?
World Community Grid enables anyone with a computer, smartphone or tablet to donate their unused computing power to advance cutting-edge scientific research on topics related to health, poverty and sustainability. Through the contributions of over 650,000 individuals and 460 organizations, World Community Grid has supported 28 research projects to date, including searches for more effective treatments for cancer, HIV/AIDS and neglected tropical diseases. Other projects are looking for low-cost water filtration systems and new materials for capturing solar energy efficiently.

- How can I help?
You can find the information in this thread:

- Is Linux faster than Windows for WCG?
If you are running any of the VINA applications (Zika, Ebola, or Faah) just about any Linux variation will be faster than any version of Windows.
For the other projects the advantage is not as clear cut for either operating system.

- I'm wondering about the efficiency of different cpus and machines
You can find the information on OldChap's spreadsheet here:
You can also add your data :

- Where can I check my stats/team's stats?
WCG site :
Free DC:
Our milestones thread:
Our Pie's thread:,2.0.html
Our Teams daily numbers thread:,3.0.html

I'll add/update the thread when more things come up. Feel free to post suggestions, share your tips, questions.
I'll try my best to keep this thread up to date.

Site comments, suggestions etc / Suggestion: F.A.Q for projects
« on: 17 February, 2017, 08:07:29 PM »
I think we should make a FAQ thread for every project that we're in to make it easy for members in case they want to join the project.
Covering hardware, OS, settings, configuration, tips, tricks, what's good, what's not... etc etc.
That way our team members can know exactly where to look for information if need and
can get their rigs up and running asap. Also it can attract other ppl to join our team
when they find the information they need at this forum.

Whoever is familiar with a project can start the thread, then we can add more info as we go.
Then we just  need to update the 1st post regularly to keep it up to date.
It's member helping member kinda thing. We've lost a huge amount of info at the old site
so if we can re create them with a more up to date version then I think over time it will attract crunchers to this site.

What do you guys think?

The idea came to me when I joined Einstein@Home. I had absolutely no idea what to do lol.
I'm not a tech savvy like some of you. I'm just a guy that love computers hardware as a hobby.
I was like "dang i wish there's a FAQ thread".

Hardware info, tips & tricks / Kaby lake build
« on: 29 January, 2017, 03:40:16 PM »
My son have been complaining about his system is too noisy that he couldnt sleep.Instead of taking it off WCG, i've decided to build him a new one.
Here are the parts:
Case + cooling + PSU :
VGA: will put my extra R9 380 in here

Total cost : $975

Also building one for my little bro. He mostly gaming so I gave him a 7600k instead of 7700k and add a GTX 1060.
All other parts are the same.

Total cost: $1075

I prolly won't  overclock my son's machine, try to keep it quiet for him. But i'll try to push to see how far it can goes. Same with my brother's 7600k but i'll keep the overclock on this one.
Will post back the numbers when i get my hands on the toys :)

I have an extra MSI Radeon R9 380 that i want to put into one of my V4 rig for E@H.
The mobo is SUPERMICRO MBD-X10DRI Extended ATX which has a built in vga.

So do i need to install the ATI driver first then disable the on board vga?
Also the card will not fit with the first PCIe slot, I used the middle one. Is that ok or do i have to use the 1st slot?
The R9 380 is kinda = to the GTX 960?
