As i understand it doesn't matter where you test your computer, clock cycles are being used either way.
To me, 43-44 out of a calculated maximum of 57.6 is low.
Why would it BSOD or reboot? If your OC isn't stable, then okay, it might BSOD/Reboot but it wouldn't do any more damage than it would in Windows.
The reason I say to use safe mode is because there's less things stuff running in the background to use CPU cycles.
Unless someone creates a LINPACK in ASM and puts it on a bootable disc, there's no real way of getting true 100% as far as I know.

Interesting thread. But to be honest I dont really know if Id add this to my bucket of golden rules.

according to the calculation I have a quad Q6700 @ 3.17ghz.
stock is 2.66 X 16 = 42.56
my oc is 3.17 x 16 = 50.72

Well, at stock i get 27 and my oc I get 33. Way off from what the calculations estimate.
by tweaking my HT and NB I can vary between 3-4 gflops, but not 20!. But perhaps this calculation work on dual core but my be overshooting for quads, i5s, and i7s.

Maybe its the 780i crap NB that all of use are using. I know mine is a ***** to try and overclock. Stable 1 minute... completely unstable the next. I cant wait to get a new MB!!!

@mincap
if you are BSOD in windows make sure you are not Overclocking your mem too much. Also check your mem spd's vs what your are actually running. Could be your HT or NB voltages are too low maybe.

According to Intel, the Q6700 should peak at 42.56GFlops, exactly the same figure as Perspolis's formula calculates to.
Maybe you're right about it being the 780i though.

Well I've finished re-doing my overclock, but got it to 4.2 this time, and here's the result. Seems to be good to me, what you think [Adz] and PERSPOLIS?

61 seems quite reasonable at 90% of your max (67.2GFlops). Nice work!

Good stuff, I could get slightly more out of it, but I can't be bothered. My 200 bclk is making my ram run at 1600, which is its stock rated speed, so with that and 4.2 on the cpu, it's nice round numbers.

Please read the second post of this thread!
I just finished writing an explanation that may shed light on a couple of queries.

@ [Adz]
You are runnig the test properly,but your chipset+ram is limiting your gigaflops performance.
Now,does it hurt your real world performance?I don't know.
Does it limit your ability to test for stability?No way.
So run LinX/IBT for an hour & if you pass the test,you are stable.


@ JimmyHart84
I like your gigaflops & your temps.Well done!
With a little tweaking,you should be able to get 62-63 gigaflops no sweat.



@ mindthecap
You are getting bsod either because your CPU is more stressed(you are getting higher gigaflops)in safe mode which means you need more vcore,or your system is overheating.

A word of caution:since temp monitoring apps don't work in safe mode,make sure your temps are acceptable with some headroom before running the test in safe mode.


@ Addictedtokaos
What [Adz] said.
I also think your mobo is limiting your gigaflops.

Thanks for your help.
Just another question - are both the ram and chipset contributing factors or is it possible that just one of them is the sole cause? Do you know of any way to test for it?

IF possible,run Everest Cache And Memory Benchmark & report your read & write values.
Also post a screenshot of motherboard-chipset page in Everest if you can.

Hey PERSPOLIS, I averaged 35.25 GFlops on my latest run, so thats close to dead on target with your calculation, mind telling me how you got that range of values?

So anyway, thanks for this guide on how to properly use LinX, as now I have another tool to use for stability testing. +rep

And to those with a similar system to me here is what I did:
1. Opened task manager and closed as many things as I could (I didn't end superfetch)
2. Only had CoreTemp running.
3. "Bled" the memory by running LinX with 3500MB of RAM size for 2 runs.
4. Waited a few minutes before selecting 2048MB of RAM and ran 10 passes, which gave me the average of 35.24976 GFlops.
