Topic: Sapphire Radeon R9 290 Tri-X OC - page 5. (Read 27807 times)

Hey everyone,

I'm really struggling here.  I got my R9 290 Tri-x OC cards yesterday and started installing them in 4 different computers.  However, what I'm finding is that the cards have a consistent drop off and I mean in an extreme way and I have been unable to figure out why.

First some details.  I've moved the "little switch" to both positions on the cards with the same results.  I'm running BFGMiner 3.9 and I'm using a bat file with the following settings (I've used configs to), but keep in mind I've tried a hundred different settings with the same results.

-I 20 -g 1 -w 256 --lookup-gap 2 --gpu-memclock 1500 --gpu-engine 1000 --thread-concurrency 28456 --gpu-powertune 20 -S opencl:auto --auto-fan

The results are consistently repeatable.  The first 30 seconds to a minute is blazing fast with speeds greater than 1 mh/s, then there is a steady drop down to essentially nothing meaning lower than 300 kh/s.

For instance, I let two of the cards run in a computer over night and when I checked them this morning the speed was 140 kh/s per card.  On the one system where I just put one card it as at 280 kh/s in the morning.

I'm totally new to overclocking and the software to do it so bare with me here.  I installed TRIXX today to mess with the settings a bit to see if I can figure out what is going on but it seems the cards simply ignore the settings after a few seconds.  For instance, when I change the fan speed setting to fixed and set it high to see if the fan responds, it does for about 10 seconds and then it goes back to whatever it was doing before.  I do not know how to verify memory speed changes etc are actually taking effort.  I can't see any evidence that they are though.

EDIT: I struck out the part on the fan having a mind of it's own because I was actually running the miner in the background and forgot so BFGMiner was taking control of the fan again and slowing it down.  When I shutdown BFGMiner the fan stayed at the speed I set.

It seems the cards are marching to their own drummer so-to-speak and I haven't figured out what is going on with them yet.  I've tried four different cards so far though and they are all acting the same way in two different computers.

One of the computers have 8 gig of RAM the other 16 gig of RAM.  EDIT:  Each computer is running Windows 7 x64.

I'm puzzled though.  Has anyone else run into something like this?

please need settings 5x sapphire cards r9 290 tri-x oc.
I have this pc.

cpu fx-8320 3.5ghz
placa 990fxa-ud5
2x ram 8g 1600mhz

I used all the settings that you have put all the time and stops.

doesn't matter how many ram I put in. the only thing I can do with more than 8Gb is setting tc over 30000.
think I will switch to linux and see if I can get this card working there.

4GB ram is not enough for these cards. my rig has 16 and cards run at 1015/1500 tc 40200 - 910 Kh stable

tried it on an older pc with 6GB ram and got nowhere close to that - 900/1250 tc 22516 - 815 Kh

hm.. tc isn't the problem I think because it worked perfectly with tc 20000. with 8-16GB ram I only gain about 20Khash/sec so I left the 4GB stick inside.
I think I've tried to start it with -I 13 or without any parameters, still doesn't start.

plugging out all power cables didn't change anything yesterday. but have done it now again.

does it help if I remove the battery from my motherboard and plug it in again?

EDIT:

tried everything, but cgminer won't start.

Do a full power drain; Shut down the system, unplug the PSU and hold the power button in to discharge the board. If it still won't start when you turn it back on it can be a few things.

Either you need to reinstall the drivers(look up how to fully remove the existing software before reinstalling).
You are lacking enough system RAM for the thread concurrency(try setting it to an intensity of 13 and TC of 8192 just to see if it starts. If it does start, you need more ram to run full power)
Or worst-case, you might have something corrupted in your BIOS or GPU firmware(unlikely, but possible).

have removed drivers, and installed new. nothing changes, cgminer won't start and gpu load is always 0%.

You need to reinstall your drivers(again, I'm sure).

I am still wrestling with my 4x 290 Tri-x OCs.

lol new problem: cgminer won't start. doesn't matter which settings or which cgminer version... think I will use that card for gaming rather than mining <.<'

Sweet! Thanks man. That config worked perfect for me and others were locking up my drivers. Much doge to you.

this is my config:


this is a steady 880 per card.. (got 3 connected now)

Motherboard: MSI Z87 G45
Memory: 12GB
OS: Windows 8.1

no out of the box settings don't work with my system. I'll provide you now with all information about my system

AMD Sempron 145
Asrock 970 Extreme 4 Motherboard
EVGA 750W PSU
4GB RAM

Windows 7 x64
MSI Afterburner
cgminer 3.7.2
Catalyst 13.12

Settings in MSI Afterburner
947/1250
GPU-Fan 50%

cgmnier config:

Screenshot:


Temps: 61°C
Power consumption: 290 Watt

Note: Monitor needs to be attached, otherwise cgminer won't start

 

so out of the box settings:

GPU Core clock = 1,000
GPU Memory clock = 1,300

Don't work?

I'll try the TC 20481 tomorrow and see what happens.

ok seems like problem is solved. needed to set clocks to 947/1250 because the tri-x uses the standard pcb, and somehow it doesn't like the oc. running stable 850khash/sec right now with my 4GB ram.

my setting:

ASRock 990FX Extreme9 - probably not worth the extra I spent on it for my 2 x R9 290 Tri-x's, but it seems pretty good.

Both cards are working and stable at just over 800kh/s, but letting them get used to mining for a couple of days before tweaking. The noise levels and cooler runs temps compared to the R9 290s are the biggest difference so far.

hm have now 4GB installed and I'm trying too tweak around with readyboost. so far I've tried a 8GB usb stick, but TC over 30k doesn't work, will now try a 16GB usb stick. oh and by the way
what bios are you guys using?

015.042.000.000.000000 (113-E285FOC-U003)
or
015.042.000.000.000000 (113-E285FOC-X003)

if all that tweaking doesn't help I will try with 16GB ram

cheers


edit: readyboost doesn't do anything, will now come with full power and add 16GB ram... let's see what it will do after that lol

btw: what motherboard do you guys use?
ah and all tri-x have hynix memory as far as I know (mine has hynix memory too)

Have you tried a couple of USB memory sticks with readyboost to see if that helps before buying some DDR3 RAM?

You should check if your card has Hynx memory. More overclock, such speed, wow.

hm.. gpu-z is installed, will look at it again. thanks

GPU-Z or HWiNFO.
