It would be nice if we could have the WU limit increased and maybe the deadline decreased a bit so when things like this happen we can keep crunching. I'm using a Volta based card and 80 WU are gone in a couple minutes.

80 Workunits per Gpu are really too small.. if server is down in less then half hour (on 7970) you run out of work.. i understand that maybe with CPUs could be reasonable.. but "hardcore business" is made of GPUs

I don't like Windows 10, too many times updated components (especially drivers) caused problems.. Windows 7 correctly configured can just do the job without any sort of headache. This is not last generation hardware so fully supported and cheap (DDR3).

This is my rig:
Asus Maximus Formula VI - Z87
Intel i3 4160 (upgrade planned)
8Gb of DDR3 1600
Intel SSD 120Gb
Windows 7 Sp1 Updated
PSU 1000W 80Gold

I proceeded with a clean install of windows from scratch, Just drivers and some basics and seems to work.. maybe some misconfiguration or something went wrong in past attempt.

It's returning valid results with some queue.

For Milky At this time these GPU are installed:
Sapphire HD7970 OC (Blue PCB, 2x8pin 12V, 1st 16x slot)
Asus HD7990 (Dual GPU, 2nd 16x slot)

the 7990 is in the second slot to have better clean air. I suspect with this configuration the Pcie Lanes of Z87 can bottleneck the 7990.. with 2 phisical gpus installed motherboard gives 8x-8x configuration. The 1st 7970 should have the full 8x, but since 7990 is a dual chip, both chips share the 8x bandwidth, a 4x-4x. I think i'll replace the 7990 with a twin Sapphire HD7970

Have 2 distinct Hosts (A Single7990 and a Dual7970) are a better option and easyer to keep temps in a reasonable range

Ps: The Web user interface of Boinc for Milkyway in my language is completely wrong wrong, worst then first editions of google translate :), it's almost impossible to understand the meaning of buttons, if you are't familiar with english version you have to go blind, bad translated and with spelling errors, It's possible to have contact with someone who can corret the translation?

Via app_config.xml there are 4wu/gpu running..
0.24 cpu
0.24 gpu
A maximum of 8 task

No cpu project are running, really i cannot understand.. i have other 3 rigs with same gpus and settings but no problems

Last chance is to reinstall windows7 but before i want to try to solve..

Dear Sirs,
recently i built a new dual GPU rig to crunch milky@home, This is the host:


all work units crunched always returns as validation error: https://milkyway.cs.rpi.edu/milkyway/results.php?hostid=775931&offset=0&show_names=0&state=5&appid=

I tryed almost everything
-detach and reattach
-uninstall and reinstall boinc
-tried an older boinc version
-a different AMD driver (latest and older)
-install latest updates (but same also before updates)

Temperature are ok (72°C on the hottest GPU)

But Server always says validation error. On client everything seems to be ok but when sent back to server status is always validation error.

What's wrong? everything seems to be ok, is there anything i can check on server side?

Thanks for your help
