If it has failed on four attempts,

On four different systems,

then it's.... garbage in = garbage out !

IMHO

P.S. It is NOT just your system.

Windows 7 Ultimate 64 bit - BOINC 7.6.33 - GPU Driver 14.1
Xeon E3 1270 V3 @ 3.7 GHz HT on
MW 1 task only - GPU @ 1065MHz - Memory @ 1555MHz 40 seconds - NO CPU tasks !
Same with CPU tasks limited to 88% - 43 seconds

dunx

P.S. Tried two tasks per GPU, and it messed up all four GPUs.... liking the sensible VRM temps though !

Theoretical yes. But windows throws around the Threads at random. I don't know any option or program that can reserve one Module.

The 323 second times apply when i only run Milkyway@home, no CPU tasks from Boinc. But i should keep the times, when i could reserve one Module exclusively.


I use process lasso on my Intel i7 - W7 system, don't know if it can help you here ?

I have two R9 280X cards and my error rate is similar to yours Tex....

I'm running two WU's per card and Cosmology on the free CPU cores.

dunx

P.S. Much as I dislike the waste of resources, it's a %age I'm able to tolerate....

P.P.S. NOT using X-Fire as ( like you I'm not a gamer ! ) - wonder if actually using X-Fire with two cards might work better overall ? ? ?

Hmmmmm. Magically I now have tens of minutes of WU to crunch (vs 1-2 minutes). Perhaps the Weiss IS listening in?


Try :-

<max_file_xfers>N</max_file_xfers> Maximum number of simultaneous file transfers (default 8).
<max_file_xfers_per_project>N</max_file_xfers_per_project> Maximum number of simultaneous file transfers per project (default 2).

dunx

P.S. Not sure I've found the right options TBH....

I get better results using 0.5 cpus per 0.5 gpus.... 32 per WU two at a time HD 5870

dunx

P.S. @ 88% CPU utillisation - too leave a spare "core" for the GPUs....

Post:
I found I needed 0.5 cpus per 0.5 GPUs to maintain a decent workload.
Dropped CPU to 88% in BOINC manager. At 100% each WU took 50% longer to process.

Post:
I would suggest that managing a system with two or more cards is made easier by mixing ATI/AMD with Nvidia GPU's, you can mix and run many projects, but a pair of cards can be set up as an SLI/X-fire pair. Each brand have their strengths on different projects, but I find managing them is easier. IMHO

( P6T7 WS + HD7900 + HD5800 + GTX 480 currently adding water cooling bit-by-bit...)

dunx

P.S. If that is an i7 4770 it has an i-GPU which can be used with the Intel OpenCL SDK - I'm running E@H on mine...

So you found my secret stash of 1000 R9 280X's cards, running in a cupboard....

P.S. Anyone else had problems with x-fire and drivers on system with two R9 280x / HD79xx cards ?

No probs on it being o/ced :), just for the average 5 they need to be run at the same clock speed, otherwise the result is meaningless.

Only 75% GPU util.? Did MW not have a dedicated CPU core for the 5 averaged WUs?



Yup ! Always feed my babies properly.... unless the GPU really isn't using over half a "core"....

HD 7950 @ 950 GHz - around 120 seconds....

dunx

P.S. If the stupid R9 didn't have sticky-outy heat-pipes it would fit in the damned PC ! ! !

Sure the PSU is upto it?

Btw I asked you this a few days ago :-

Btw I just had a quick scan of your valid 213.76 cred WUs & some were down to the low 500s.
Was the time you gave with the GPU at nr. 100% load?


Mikey
So any spare C2Qs or 5850s? ;)

Also, you never did confirm if the results you gave for your grx cards were at stock MHz, are they?


Sorry work gets in the way of my fun....

PSU is fine, but the Motherboard isn't.... only a GTX 480 will work ( bulletproof build quality and it's hot anyway ! And very noisy ! )

The GPU is around 75% utilisation, CPU is down at stock clocks for stability ( used to be at 4GHz 24/7 ) variation will be due to SkynetPOGS or MW CPU WU's (IMHO).

dunx

P.S. It's more likely that the first few Wu's were run at stock clocks, but as I'm an OC addict.... ( Sorry ! )

Thanks, I appreciate your input, just wish my tired, burnt-out old Asus P6T7 WS could hold it's two HD7xxx cards without crashing....

Post:
I think they are just seeing the added latency from a PLX type interface, the native x16 slots are fine ( up to three in use), but add a fourth or use seven single slot GPU's and the interface hardware shows it's delay....

IMHO, not many BOINC projects require "gaming" levels of bandwidth.

Anyway hope to find out within a month or two !

dunx

P.S. In general they saw about a 10% shortfall, hardly PCI-E x1 performance....

I have a pair of Asus X58 boards here - both with burnt out ATX 12V pins.... P6T6 WS and P6T7 WS, neither have additional PCI_E connectors for the GPU's - but the X79 now does.....

dunx

P.S. I just bought a short extension lead and soldered the female half to the board, and the male half replaced the burnt out ATX connector on the PSU ATX lead : - )

P.P.S. GTX 480 and three GTX 460's, VS HD 5870 + HD 7950..... now added a R9 280X !

CPU useage of around six seconds is a bit silly...
