Serious Problem - AMD 6000

[Evil-Dragon]

Check your memory timings in BIOS. Make sure they are set correctly.

Allrighty then... starting to get mission critical... Facing a full 2 weeks now without getting this resolved...

Removed C'n'Q, no C'n'Q option in BIOS to disable... WPCPUID still shows running at max speed on both cores, even though it's only running at 1% or less usage...

Boinc comes on, not even 5 minutes and it takes a dive, pretty sure my old k8-1.6ghz performed better...

If anyone else can shed some light, please help, I'm about to loose my spot in the top 10k in the world...

Hi Evil Dragon -- memory timings are all on AUTO, I'm not an OC kind of person, so nothing was changed there... RAM still the same as on previous board, 4 x 1GB DDR2 pc800 DIMM...

Hi Riaan,

What version of BOINC are you running? ...and in TaskMgr is it BOINC taking all your CPU? ...what priority have you set for BOINC if it is?

[vaughan]

So let's recap: are the temps all OK? At IDLE its OK, under load (BOINC running) its performance drops 100 fold? What's the temp like under load?

Have you tried re-seating the hsf on the CPU and used a heat conducting paste eg Arctic silver?


Have you tried using only 2 x 1MB sticks of RAM instead of the 4 sticks? I read somewhere that some m/b cannot handle 4 sticks properly.

Hi Strongbow,

Microsoft Windows XP: Professional Edition, Service Pack 2, (05.01.2600.00)
Starting BOINC client version 5.10.20 for windows_intelx86

QMC - 50% - 81MB mem usage
Ufluids - 50% - 31MB mem usage
boincmgr.exe - 0% - 8MB mem usage

Boinc is set to run at 100%, same as what my x2-4600 was set as.

Hi Vaughan,

Temps fine, see attached image for stats when idle... Temp under load climbs 6 degrees, mb climbs 3degrees... not even bothering really... Asus Probe is giving me warning for MB at 45 degrees, but reckons thats BS, I've run hotter before, just installed it to get stats so not set up yet...

Remove both hsf / cpu, reseated both after checking for broken/bent pins... arctic silver applied again... running a coolermaster centurion 532 case, front intake, rear exit, both 12cm so airflow is good, cpu fan channel for air from outside... all sata cables, even dvd, so airflow in case is unobstructed. 1 ide cable for os drive, round cable. no 1.44mb.

400w psu, onboard graphics set at 128mb, not a gaming rig, built for work/boinc

haven't done the 2x1gb check yet... expected it to work as it did in previous gigabyte board. board is asus m2n-mx, can take 800 DDR2 4gb total. had memtest86+ running now for 4 hours, no errors, was at 19% when i killed it. will test 2 dimms and reply.

[Strongbow]

Coming from the S/W side; download 'What's Running' and save a snapshot before BOINC and then run compare when it has it's slowdown to see if there is anything cheeky in there.

[riaan]

comparison.xml included in zip... Can you see anything funny?

[riaan]

aaaaaaaarrrrrrrrrrrrgggggggghhhhhhhhhh............ ...

have removed 2 dimms, slots filled now ia a1/b1, manual says correct for dual channel...

I'm trying to type this message, im a quick typer.... every damn word i type takes 30 seconds of one letter at a time to come up...

looking at asus pc probe, voltage on vcore is jumping between 1.3V and 1.41V in a slow procession... 5 maybe 10 seconds between jump... every time it hits 1.31 the machine is crap, higher up it works semi decent but still at slower speeds than my x2-4600....

I'm thinking of getting on the phone to Asus first thing monday morning...

--> I have another board/cpu... same board and chip... will build it tomorrow, and just replace what i have in this box, see if simular situation returns...

this is absolute crap.... sold 1 x2 4600 and bought 2 amd 6000 for boinc, and i havent seen anything for it so far...
