Errors on prime 95

Chronictank · 11 Apr 2006 at 20:09

What exactly do they mean?
My cpu is running at 30oC atm, but the voltage is at 1.37 even tho i have set it to 1.40 (but i assumed less voltage was needed so the system reduced it).

Ok to the problem;
i ran the in place large TFT Torture Test and it would give the error:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt.
Torture Test ran 0 minuites - 1 errors, 0 warnings

According to the stress.txt this is a hardware error, so does this mean i have reached the limit my cpu will go or i have just chosen some funny settings?

Opteron 165
FSB: 289
Multiplier: Auto
Voltage: 1.40v

Thanks in advance

Clocked back down to 2.3 the results are 100% pass

- AMD Opteron UP 165 Dual Core San Diego 1.8GHz 2MB Cache
- G.Skill 2GB DDR HS PC3200 (2x1GB) CAS2.5 Dual Channel Kit (F1-3200USU2-2GBHS) (MY-007-GS)
- DFI LanParty UT NF4 Ultra-D
- Seasonic S12 600W Silent ATX2.0 Power Supply

FSB: 288
Multiplier: Auto
Voltage: now 1.425, the board seems to still only read 1.39v

Memory is running at default (Tcl: 3 Trcd: 3 Tras: 7 Trp: 3 2T Timing)

Will see how it goes now
I am 100% sure the memory is fine as i ran a 8 hr memory check on it when i bought the equipement (about 5 weeks ago)

How do i stop the board "under-volting"?

Edit: Still get the error, giving it a little more juice (1.450v), 1.42v on smartguardian now

Tnx in advance

1.450 is looking promising first test passed ^^

edit: Error after 6 mins :<i guess ill put the volts a bit more

Going good so far, self test 1024k passed, cpu is at 49/50 oC

tnx for help all.

Also do i have to run 2 instances of Prime95 and set affinity to each core or do i run 1 and let the program decide when im testing the rig like this?

Is your memory on a divider, to me it appears to be running at 288mhz?!!! To run two instances of prime have a look here

sorry to be a noob but i have no idea what a divider is :<
where do i find that out?
The memory is running at 236.5Mhz according to cpu-z
Tnx for the link i was running a single instance of the program before will try with 2 now

Ouf CPU 0 fails when i run 2 instances on the Small FFT test,
but when i run CPU0 alone it runs through them fine.

It needs yet more voltage it seems, i read here people were running it at 2.6 at 1.40 v :s ?, i will give it one more boost to 1.5v but dont really feel comfortable going over that as it was peaking at 52oC when i ran Prime95 for a hr or so

CPU 0 failed when running 2 instances again, ran succesfully with only 1 core doing work.

Will play some more tomorow after work

Mobo is a DFI Lanparty UT4 NF Ultra-D, bumping the ram voltage a bit

Ok the divider is set to Auto, so i ran cpu-z and it says
FSB

RAM: CPU/11

I am using the following cooler:
Zalman CNPS9500-LED Aero Flower CPU Cooler,
but currently i only have 2 fans in my case as 2 of them began getting too noisy (old fans so ball bearing are on the way out)

And tighten up those mem timings, you might need to put the memory down a little.

i been reading the other thread and it makes no sence to me whatsoever :S
I did read http://tomshardware.co.uk/2004/01/19/ups_and_downs/index.html
and its cleared it up a bit, but its still fuzzy tbh.
If decreasing the timers increases performance why doesnt everyone just set all the times to 2 - 2 - 2 - 2 then :S, or are the timers dictated by the hardware in which case how do i know how low to take them :s

tnx in advance

i will start from the ground up again i think

thanks for the help all its much appreciated

It also says the memory is single channel, did you insert the memory in the right slots, as in both in the yellow or both in the orange slots?

no i didnt put both in yellow/orange
initially i did do this tried to install windows and got file copy errors, swapped them over to the orange slots to see if it was just a faulty mobo got the same thing. I ran memtest to see if the memory was playing up and it was throwing out errors like candy on haloween after address 1024 (the second chip). So i swapped it to 1 yellow and 1 orange, ran memtest and there were 0 errors on a 4 hr test.
So figured i just had them plugged in wrong, i didnt notice it was running on 2t timings until it was mentioned here, so im long past the returns date

edit: you said to tighten up the timings, what do you recommend i use?

thanks in advance
