How do you "burn-in"?

[jhuezo]

Hey--

Just set up my new rig:

Lian-Li PC-60
OCZ PowerStream 520
MSI K8N Neo2 Plat.
AMD64 3200+ (0444XPEW) @ stock speeds for the time being
1gb PDP w/XBL
AS5/XP-90 + Tornado (on cpu)

I know the AS5 goes through some "burning in" as does the RAM and CPU. I'm just wondering what I have to do to burn it in. Also, is it common to start off with the following temps: 26*C (system), 39*C (cpu)? Vcore is fluctuating between 1.39 and 1.42 according to Core Center. Is this fluctuating normal too?

Thanks!

[ilal2ielli]

those temps are fine and the vcore fluctuation is normal.

now, to burn in your system you can use any program that will stress your system or just use it as you would normally. you don't really need to burn it in, but if you plan to overclock, it might help you reach higher speeds.

i usually use prime95, superpi, 3dmark01, and memtest86+ to test my system's stability after overclocking, and to "burn it in" at that speed. i usually run prime95 and memtest86+ for at least a total of 10-15 hours to make sure my system is as stable as i want it. if you're going to run everything stock then there's no need to do anything other than use your computer. as for the arctic silver, after about 200 hours of use the thermal properties should be at its optimal level and you should notice a decrease in temps, but nothing major.

[jhuezo]

Unless I can run memtest86+ in windows, I don't think I'll be able to use that. I don't have a floppy drive. I don't have a USB flash drive either. Memtest86+ runs by booting from a floppy right? Any other way to run the app?

Thanks for the advice. I figured that's what it meant, but I wanted a clear answer.

Good man, be well.

Just get the latest CD-Rom image and boot from CD.

You also may want to try toast.exe (google it). It'll heat up the CPU nicely thus helping to settle the TIM.

Burn-in in case of ArcticSilver (BTW, with AS3 i get about 4-5C lover temps that with AS5) means several thermal cycles - 15min in max temperature, then 30min with minimal temperature and then again - and repeat 10 times, and then your TIM is well burned-in
On www AS they recommend much slower process that took days. Should be better not hurry, of course...

Burn-in in case of CPUs usualy mean let it run at very high Vcore with only low overal Mhz speed for day to "get it burned-in" the socket - some even claims that after this, CPU usualy overclocking better. Could be. But I did not believe in this.
I burned-in my oldie Barton and it still maxed out at 2200Mhz while need 2.1Vcore to do this
(burned with 2.2Vcore and 800Mhz and killed my Epox 8RDA+ with this experiments later...)

So much for Burn-in

[enzoR]

burn-in really helps ram thogh

[mcnbns]

Yeah, my CPU did not benefit from burning in, either.

I haven't seen any gains myself from RAM burn-in (because my motherboard is holding me back from seeing how fast my RAM can go), but I've seen tons of other people rave about it, so there must be something there.

[jhuezo]

Well, I've been trying to raise my HTT in 5MHz increments. I'm at 2.5-3-3-7 and 245MHz. I'm superpi stable and can achieve a score of 36s (1M test). Sandra Memory bandwidth benchmark keeps showing improvement, too.

I still haven't run Prime95. I think I'll run it when I hit 2500MHz. I should probably get 3DMark01 too. What's that benchmark tool good for? What does it stress? What are good scores?

Thanks

By the way, this is the first time I've ever built a PC and first time overclocking O:-)

[winterburnd]

I should probably get 3DMark01 too. What's that benchmark tool good for? What does it stress? What are good scores?

Well good scores in 3dmark01 really depends on the kind of hardware you have. Also, This benchmarking program is more for stressing everything in your computer since it fails (freezes) easily with unstable hardware.

But if your wanting a laughable comparison I get about 9500 points in 3dMark01. Namely cause of my crap video card.

[komer]

is hot cpu tester good for burning in?

[trodas]

komer - definitively it is Prime torture test is optimal


winterburnd - mine are 11191 only too, because of FX5600XT crap
( http://ax2.old-cans.com/show.php?p=d...8&c=8&d=1&v=v2 )
Another laughable "score" Im affraid...


mcnbns - I never ever saw any burn-in improvent in ram's OC Quite frankly, either the ram was capable, or incapable and then nothing ever helped me...
And I even shave the chips so I can see the cooper backplates of the actual ram dies, put a monster cooper heatsinks on them or overvolt them, till smoke almost start comming from the voltage regulator and mosfets...
I realy like to see any examples of ram burn-in, tough

Faith is the last that dies

[komer]

yeah,i was wondering what can memory burn in do?

[ilal2ielli]

i've been successful with cpu and memory burn-in. my 3000+ winchester that did 2.4ghz at 1.525v was able to do 2.5ghz at 1.55v after a month. and my ocz plat rev2's did not do 270@2.5-3-3-10 at first, but after a few days of burning in it was 100% stable at that speed.

[jjcom]

yeah 3Dmark's nice. looping...yeah, allowing my processor to heat up helped out with temps...I turned the CPU fan way down...the computer locked up, but my temps went down by about a degree...which was nice.

3Dmark01 scorse on current rig...something like 16.5k I think...I don't remember for sure

3Dmark01 scores on Pentium 2...495...

jjcom

[craig588]

I think a good score these days is 30K, you can get that with a stock XT PE and stock FX55 IIRC. I have pulled 34K-5 on air with a SC system so that might be something to shoot for.

[IvanAndreevich]

Anybody tried burning in the CPU like this -

1) Set highest possible vcore
2) Set lowest possible speed
3) Torture it ..

After a few days of 100% load it can give more stability for stuff it wouldn't do before. OR it could make the CPU like volts better

folding@home 24/7

nice way to burn in & donating at the same time

[trodas]

True, tictac I folding my ass off all the time

...however the results with say, 800Mhz CPU won't be so amazing Even my 2600Mhz AXP-M seems lazy for folding

[Dumo]

I used stock hsf for testing if neo2 can post, which fortunately it was. Then froze the cpu. Never run with stock speed afterward

[Entity_Razer]

the weird thing after reading about AS 5 is that (I have it on for..... 2 months now with say a small 500 hours of usage or something(1.5 months has the as5 been on, and my comp isn't on 24/7

In the beginning my temps where lowwwwwwwwwwww (like in 34°C low on 2200MHZ,1.75Volt


but now my temps begin to rise to a idle of 34,35 and my stresstemp (when folding) is at 43 :o

it never used to rise above 40°C

what up with that?


I guess time to re-apply AS5?(boy is arctic ever making money on me =) )

[trodas]

AS5 is crap, use AS3 for even lover and time-stable temps

I repasted all my machines with gain 3-6C per one - except passively cooled server, where the TIM did not matter, as CPU and heatsink get the same temp

...but this is a sort of OT there, or not? Okay, you have to burn-in the AS3 as well, hehe - now are we on topic

[Dunk]

I think there's more urban myth to burning in than anything else really

[jjcom]

Your temps could go up when the heatsink or something gets filled with dust (or in my case cat hair)

jjcom

[Disposibleteen]

i still like good ole D2OL for burning in, it puts the cpu@100% all the time and keeps it there, i used it to burn in this rig...

[IvanAndreevich]

I don't like AS5 either.. AS3 worked better IMO. AS5 too viscous.
