i see, still cant imagine the chip is degrading, maybe someone else can help you
determine whats up, maybe it looked like it was stable with linx, but wasnt on the long run?
some bsod's you can get by normal daily usage, playing games, browsing etc,
even when programs like ibt or prime look stable, i had the same a few times..

ooooo, you so lucky, im paying 365 Euro(473 U.S. dollars) for mine..

Currently Testing my 3570k at 4.8ghz with 1.32volts and it seems pretty rock solid atm...

1.32V might seem stable at 4.8GHz but I would bet my check that its not truly stable. I can boot at 4.9GHz @1.38v and pime95 for over three hours but start actually use the system and it will crash. My chip needs 1.45v @ 4.9MHz to be truly stable. At 5GHz I'm at 5.00V to be 24/7 stable and that is just to high for me. Even at 5.00V, load temps never break 86C but I'm just not comfortable pushing that voltage fulltime. I upgrade every two or three years so life span isn't as big of a deal for me. I run my old core duo clocked to the hilt (3.5GHz) and its been running 70+C for over four years. If memory serves, 75C is the thermal max on that chip.

After several testing u might be right. but atm it seems i need a voltage offset of +0.045volts to make 100mhz clock stable after my stock voltage limit (which was 4.3ghz) this is true so far for me till 4.8ghz which required +0.060v.

Sadly im temp limited atm because when i hit 92*C in prime95 i decided to back down. im temp limited again at least in benchmarking & stability testing.

i think ill stick to my 4.5ghz 24/7 @ 1.19v lol. which is still pretty stupidly low according to my friend.

That is crazy low voltage. What kind of load temps do you get at that voltage?

65*C in Prime95.... Everything else... 35-55*C lol.

Hyper212+ with an ultrakaze on it pushing air directly into my coolermaster exhaust fan. Works wonders.

If someone have some advice for me. I test my 3570k@4.2 (asrock extreme 4) with scythe ninja 3 on prime95 for 12 hours and it was stable,max temp was 74. I 1st used a fixed mode with 1.19 vcore,then offset with -0.80 wich gave me about 1.17 vcore. LLC set to 2,C states disabled. But when browsing the net,or playing bf3 for 30 mins my computer freeze or i got bsod. I manage to get it stable even with 1.15 vcore fixed mode @ 4.2,but while browsing or idle it freeze or i got bsod. I am crazy,dont know what do to,someone could help?
post #858 of 1508
Now even freezes at 4.0 with 1.20 vcore, So silly.... If I set it above 1.25 vcore temps in prome are almost 90,about 88,89...

]The Asrock extream boards are known not to deliver accurate voltage as set in the bios. It could be that you are still under the voltage needed to be stable. I would reset defaults in the bios and use the auto over clock features if all you are after is low 4.?? clock. It would seem that something is way out of wack there. I wouldnt think you would need any offset or loadline changes at 4.2.. I used that that exact board for about a week before switching back to a gigabyte. I could not get a sable 4.5 out of my 3570k on the Asrock but the same chip on my gigabyte board and 4.9 24/7 stable is no problem. I wouldn't be afraid to throw more voltage at it, you should be compleaty safe up to 1.38+v with a good cooler! I was running 4.5 @ 1.28 on a lapped TX3 and prim load temps never passed 83C. You might want to try and reset the cooler



What a long way I've come since August and way too much money... thumb.gif

You haven't played with memory clock yet have you?
Also check that the board set the correct memory timing in the bios, sometimes the bios likes to throw its own timings in the mix and that could really throw a wrench into the works.
