but system dont hang so far :P

do a quick run for comfort, 2 hours or so, if it dont fail then, just enjoy it bro. I dont see the point in testing for so long. does 2 or 3 hours just consider it stable, and enjoy your o/c. If it crashes down the road then tweak it, the same way you would if you crash during prime 95.

[PC_User]

if i buy this

4000RPM fans buy 2 of them for my nortua u think the temp be much better?

Do you realize how loud those will be. You'll lose about 5*C at most but the noise isn't worth it IMHO.

Thats my method as well, test for 2 hours, thats enough for me, if something fails i go back and test again with different programs.

Thank you. I'd thought no one will ever agree with me. Why put it through the stress of 10 hours or 12 of prime. Just enjoy it and use it. If it crashes tweak it just as you would if prime fails. I've been running my 4ghz daily setup for 3 months now ever since I went core i7 and it has not crashes once. I have never ran prime on this setting. If it crashes a month from now, i'll simply tweak it, thats it. Same with prime, you run it for 12 hours and it didn't crash. What if it would have crashed after 14 hours? You never really know if your rig is stable, enjoy the damn thing and stop wasting hours just stress testing it!

[methimpikehoses]

Just out of curiosity, what temps are you guys getting?

My i7 920 (4GHz @ 1.344v CPU-Z) is under a TRUE-120 and I'm getting about 39-42*C idle and 73-77*C load.

Just wanted to compare to see if my temps are normal.

Lap that puppy to knock 5-10C off load temps.

[Fafeifa]

For some reason my temperatures seem too high..I can only get my oc to be stable with 1.35v vcore and my temps with prime95 around 85*C
I read up some specs the fan speed for Nortua is 1300RPM and TRUE 120 is 1600RPM and i see that other member with TRUE 120 at 3000 RPM?

I've been running my noctua with the 2 fans that comes with the vigor monsoon and use the noctua fans for my case, They should be similar to the ones found with noctua, My 4.0 ghz stable with 1.36v is 82C although i have a good airflow which also helps. Again please don't assume that your heatsink is inferior to the others because many variables can come into play such as airflow, speed of fans and ambient temperature. The noctua's mount is the best i've seen, last one i used that was similar was some Alpha cooler back in the AMD XP days. The noctua's mount is so easy that you do not need to take out the motherboard when u are ready to perform a cooler dusting. I can live with 1 or 2C higher and i have yet to lap this 2nd 920 set up. But taking out the mobo is a huge PIA just to perform a rutine maintenance operation. To me the TRUE is the best but at the expense of convenience. Which is one of the reasons i use the Noctua and recommend the Noctua.
I think the temperature is due to the speed of the cpu and not the voltage. The cpu's runs really hot specially HT on. So if u want to stay in the 4.0ghz in a hot climate WC or extreme Air is a must. I will probably back down my clocks for the Oklahoma summer due to the enormous heat this thing puts out. I have 2x 15k SAS drives which i plan to add another 2. So this is something i have to take into consideration.

[Fafeifa]

would 2 kas 3000 fit on my nortua?

It should fit with no problems but you may have to change the orientation of the heatsink since the extra 10mm of the fan will not let you use the 1st slot. I would not do it at 45dba but thats just me.

Thats true. I might just buy 2 higher rpm fans, but problem is I dunno if it will fit directly on. But i do some research :P thanks for your input

[QUOTE=Chicken Patty;3735025]

if its stable, sure.

Also depends on what volts your using

[hlonipha]

lol... In the AMD days I bought a Delta 110cfm fan and I thought the computer was going to take off flying. took it out and replace with a lower rpm fan. Once in a while I plug the fan just to hear that thing. it is louddddd.

I hear loud enough whenever I'm working on a 1-2U rack mount server

[dejanh]

@2slick4u - Use Memtest86+ 2.11 and Memtest HCI for a few hours each on it and see if anything errors out. If yes then you need to increase the timings, if no then you are good. You do not want to have your DRAM cause errors as things will get corrupted over time.

By the way, I am glad dropping the memory multiplier worked out. The chip obviously has a weaker IMC.

You never really know if your rig is stable, enjoy the damn thing and stop wasting hours just stress testing it!

I agree as well. My Q9450 (at 3.8Ghz and 1900fsb) I only ran P95 for 1 hour to test stability! Then I played games, downloaded, surfed, all the regular stuff I normally do, and did increase Vcore initially a never a crash or bsod since (almost 1 year now no crashes, and never a stress test more than 1 hour long). If it's not stable, it doesn't bother me (as using computer as I normally do is stable).

My buddy thought I was crazy, and says I should run P95 for at least 24 hours. I said ok, hows about my car? it runs, it gets me to and from work trouble free. But I don't know if I could run it full speed for 24 hours straight, and don't care, thats not how I normally drive it.

btw
my i7 920 is also 1 hour P95 stable at 4.2Ghz, same deal, now just playing games and surfing the web, burning disks, and all the stuff I normally do to test if I am stable. 1 month no crashes at all (only had the i7 a little over 1 month)

[Infa]

eheh WORD! "not so sound to immature" but thats' my motto too! If crash = tweak as above speaker.
if it crashes after 10 mins Blend prime, sure something is wrong. but why bother priming all night and days...geez
if it is used as a server then maybe, but servers are usually dual socket, or racks and not overclocked, and therefore stable.
enjoy the speed!

[2slick4u]

I cant seem to get my kas 3000 fan to fit on my heatsink without it hitting my ram and my ram is on the second slot already :S

[2slick4u]

Never mind I got it to fit but i cant fit ram in my first slot :P
but temps are better with this fan

[Chicken Patty]

yah stress testing over night and all that stuff to me is pointless. Enjoy it, if it crashes, just simply tweak it as if you failed prime. Same crap, different toilet.

[dejanh]

I do generally agree with this. I believe some amount of stress testing is good, but in general go with it and if you have problems then tweak. Exception are those people that do 24/7 work with full load on all cores/threads as they need absolute stability. But this kind of goes in the face of overclocking too since any overclocking always increases the chance that the system will be unstable, regardless. Moreover, if it is just a small instability it may now show for weeks.

By the way, those that haven't done so already head on over to my contest thread here http://www.xtremesystems.org/forums/...d.php?t=220984 and drop me a line. I can only win with your support!

Thanks guys

I was using 2 ultra kaze on the nochua back in December worked fine - use a fan controller.

Come to my conclusion, i do a x20 run of Linx, that's the "heaviest" prog for the cpu, if it finishes, im satisfied, if some problems occure later on, I'll deal with it!

Ok, nough with this not all of us got this 24hour paranoia for some silly reason, seems like become some kind of stupid contest making the cpu last the longest in a stress test that NEVER will happen in an everyday usage EVER! Sincve WHEN do you play 24hour straight? and even then, the CPU will NEVER get stressed like Linx EVER never in a game, the graphic will cut it before the cpu if that's the case or something else, i think as long as people understand pretty good how the bios and tweaking goes, the cpu will be the strongest part in the system, people never thought game crashes almost never are becouse of the cpu? Mem, and gpu are first to strike. now to sleep
sleep tight my OC buddies :P

@SteveRo - thanks for dropping me a line in the competition thread again

[2slick4u]

I bought a zalman fan mate controller doesnt seem to work :S
no matter if i turn it to min or max i see it still at the same rpm 2800RPM? any advice?
