LinX - A simple Linpack interface

[UNSTABLE_HERO]

as xpatar says...13 of 20 test complited an finished no errorsi have the feeling that sometimes linx reports false errors especialy when running it and trying to open any program like hwmonitor or media player...i used linpack from occt for 3 hours then occt(cpu / small fft) for 3 hours and sometimes linx give me errors in an minute or runs fine for hours with the same settings of course!i have an i7 system if that helps

[donmarkoni]

Did you consider that it stresses your system more then any other program, so it fails for that reason?

[UNSTABLE_HERO]

it stresses a lot but i dont find it so normal crashing after 2 minutes and when i give a second run with everything unchanged it finishes test with no errors after 4 hours,of course an error is random and can happen!so if u pass 4 hours linx u run it again because you are not sure....!or maybe finishing at 13 of 20 tests and reports that test finished with no errors is an error?yesterday i uzipped it again because the prog was getting crazy and didnt stress the cpu correct!5000mb 20 runs and i had only 59c...while with occt and prime cpu hits 70s!now after deleting the old file and unzipped it again everything is ok i hit 74c

[xpatar]

Did you try running the program from drive C:\ ? Does this make any difference?

i keep getting the "not enough memory" error. What does that mean?

[MaxOC]

I started using LinX to test my system (Q9550@3.6). The starnge thing I noticed is that while using version 0.63 the Gflops were consistant around 50 and the temps reported during the test were around 65c, with version 0.64 my Gglops are very inconsistent and stay around 30-35 and the temps are 10C lower around 55c.

Nothing has changed on the system, in fact I can run 5 cycles with 0.63 and get max temps and Gflops, then run 5 cycles with 0.64 and get 34Gflops and 10c lower temps.

Has anything changed in the latest version that could cause this discrepancy?

Either you're not using the swap file or you're asking for too much!

Switching back, thanks for the heads up.

Can anybody else confirm the issue with version 0.6.4?

UNSTABLE_HERO reported that even though he had chosen 20 runs from Linx, it stopped at the 13nth run reporting that the program finished without any errors.
Can we consider it as a bug of the program or some setting fix.
Press 4 for ...Greek, it was Greek

I have had this same thing happen, but it is not blue at the top where is says you finished without error, it is in red, and windows reports the program has stopped responding, which is normally a sign you aren't using enough vcore.

I use LinX as a starting point for testing stability to give an idea if it is close. Sometimes it will pass, then fail with same settings a day later, I think is has to due with the conditions when you were testing, such as ambient temps, or other programs being open possibly. Prime blend will do the same thing, can pass it several times at the same settings then fail at random. None of these programs are 100% consistent IMO.

It simply means that your overclock was on the edge of stability. Drop ~200Mhz (and for the sake of stability decrease other values as well such as RAM mhz, possibly bclk etc.) and you will pass all your tests many times any day

[exodusprime1337]

so i'm curious, does this work on amd rigs.. and if it does, is 10 passes or 5 passes enough to test just general stability in the quest to find a max oc?? i'm a bit nubish on the oc'ing, currently got my p2 965 c3 at 4.1Ghz 1.55v and it passes 10 passes and i'm wondering if i need to run more, and what settings should i use?

here are the system specs

asus m4a79t deluxe
2x2gb ddr3 1600 cl9 g.skill 1.5v
phenom 2 965c3 4.1Ghz 20.5x200 1.55v
4xg.skill 64gig ssd in raid 0 + 1 wd 1 tb storage drive.
bfg es 800 psu

[zalbard]

You need at least 20, max memory.

thanx for the reply, i'm getting a bluescreen crash about 5 tests in, in orthos linpack and p95-24 hour run small fft and blend on two different occasions i get no errors, but linx fails almost 4 minutes in, is this the settings or is this my computer, i always though 24 hour run of p95 or a orthos linpack was enough, this just bluescreens me?

What are your temperature in p95 small fft and linpack? If the temps are at the limit with p95, linpack will push them over the edge and cause instability.

it was blue to me btw i think occts linpack is more reliable and i have same max cpu temps as with linx!i7 @ 74c(22 room) with both progs under load!
from changelog:
LinX 0.6.4

- added an option to run tests for a specified period of time. Use the drop-down list to set minutes or times to run tests
- small UI redesign/enhancements
- graph windows now correctly save their positions on program close
- fixed a somewhat rare bug leading to false LinX errors when CPU usage was high----------( i think )----------------------------------->(MAYBE NOT FIXED 100%)
- added new command-line options, fixed found bugs in older ones (run LinX.exe -help to view the list of command-line options)
- added seconds to filenames to prevent overwriting

i barly edge over 44 in linpack, and linx is no higher, maybe a bit lower, the room is at 65f/18c or so but it doesn't go high, in fact i don't think i'v ever hit 50 on this chip... Problem is, that doesn't equatte to anything more than 4.0Ghz, can't get anywhere near 4.1, was hoping to but it isn't happening.

Wow! nice temps. Sometimes OC hits a wall regardless of the temperatures, anyway, 4.0ghz is still not bad

Can anybody else confirm the issue with version 0.6.4?

I have the same issue on occasions too. I'll start up, run the test, and when I normally hit the 70's, it goes down to low 60's. Gflops also drop from 61 down to anywhere between 35 and 55 when it doesn't run properly. Task manager shows nothing else using the CPU and this is on a fresh w7 64-bit install. C1E and EIST are also off.

So would anyone agree that 0.6.3 is likely to be better for now? (in our cases)

[IvanAndreevich]

Dang, times have changed. Prime95 is officially out for me, and LinX is in. Stable in Prime for 30 minutes. LinX gives 5C higher temps than small FFTs, and it BSOD the system after only 1 minute.

Спасибо за интерфейс.

[namurt]

linx doesn't appear to be working for me. i downloaded the latest version. fired it up, and... nothing. it doesn't ever seem to initiate the tests. realtemp is reporting no load on my cpu. temps aren't going up. there's no output. what gives?

itb works fine, btw.

Don't throw prime just yet...
Testing with large FFTs will reveal QPI volt problems. However small FFTs are inadequate for I7's. A Linpack based program is better.

[AlleyViper]

Nice, a consistently 12h prime blend stable setting wouldn't complete a 20 pass test, failing always near middle after 5 tries. A small NB bump solved it, testing exact amount of memory for multiple passes.
On the other hand, a setting that will pass whatever linpack I throw at it or prime, once failed me under Linx at a time I was stress testing my PC and closed Winamp and Firefox. It seems like closing both programs triggered it's failure. I report same temps for OCCT, linx and interburntest's linpack.

Thank you guys for all your input. It is appreciated.

I feel sorry for all those bugs and inconsistencies. In fact, I'm still surprised there's so many of you out there using this tool.

The thing is, communicating with a foreign process, and especially such a specific one as Linpack (which sometimes acts weird by itself, but in no way I mean here to accuse it of my own glitches), is tough. The sensitiveness to specific system configurations doesn't aid in solving the issues too.

Having said that, I can only suggest those having issues to try some previous versions (that's actually why they're listed, solving one issue without introducing another one is still a feat I have to learn ) if you still want to give LinX a go. And I think it's time for me to stop adding features and focus on solving errors.

You're welcome. I was always curious whether someone with such nickname as yours could know Russian. Figure, my assumptions were correct.

[pcnazz]

New this week my first ever Intel platform and love it so far . JoeBar brought this to my attention and OC Nub threw up the down load . My clocks were 6 hours p95 stable but I gave this a try and like it a lot . Thanks again JoeBar & OC-Nub . Turbo Enable 24/7 , purchased 2000 GT CL8 Dominators today !

For me is the other way around. I was stable for 25 loops (max gflops) but Prime 95 would fail within 3 to 5 hours every time.

I think Linpack is good to test quickly for major stability issues, but for fine tuning long term stability, Prime95 is still the way to go.
