If you got a blue screen and you're overclocking, it's probably safe to assume your OC isn't stable. Try bumping the voltage slightly and stress test some more.

the thing is, i left in running orthos and everest burn test for 8h without any fails. Can i find a log of the bsod?



Thank you


Edit: I uploaded my mini dmp file to http://www.osronline.com and got the following error code : 0x124_AuthenticAMD_PROCESSOR_CACHE_PRV

I read that it is related to hardware and one of its causes are OC. so its very likely that the bsod cause was the overclock...

But what happened though? What can i do?


Im really clueless at the moment

Well... maybe i shouldnt be so annoying but before i ask this questions i usually do a google search. Sorry anyway.


Amyway... I ran far cry 3 on extra for 1h and got 41.4º max temp on cpu... Maybe the GPU heated the case but seriously doubt it...


I also uped the voltage a bit 1.36875v -> 1.3750v.


Questions about the stability of the overclock at the moment:

1: I got 41.4º while playing far cry 3 and a bsod. Can i assume ORTHOS + everest burning test arent enough for a full cpu stability check? Is 41.4º still good or kinda meh?

2: I read that voltage software may give false values, but i got 1.41v max on cpu core while playing far cry 3. Enough reason to be wary or should i just ignore it?

3: Ram timings... I copied them from someone who was reviewing them and got this values (he said he could go way further though). Are they fine?



Will post what NB values can be changed on the board so you can be more precise with the help.



Thanks for all the help and being kinda annoying

I use Prime95 and OCCT for stress testing, at least 8 hours each before I determine an overclock stable.

For voltage 1.55 is your maximum on air cooling, so 1.41 is acceptable. As I mentioned before, you shouldn't worry about your temperature until it goes above 62C during stress testing.

Here are the values that are related or may be related (due to my ignorance i dont know):

CPU ratio and voltage:

CPU/NB Frequency (min:4.00x - max:10.00x)
VDDNB over voltage
CPU VDDA voltage

Hyper Transport Configuration:

HT link frequency (min200-max2000mhz)
HT link width (8 bit-16bit)
HT overvoltage

Chipset voltage:

Chipset over voltage
SB over voltage


==========================================================

1st: When i ask about temperatures, they have to be good enough for the computer to last a long while and survive summer also. (i wont dastricly sacrifice "durability" for performance)

2nd: when i said 1.41v my question was: "if i have a max voltage on board of 1.3750v how can it detect 1.41v?) I also admited that it could also be a software error but since im a retard and scared i want to be sure biggrin.gif

3rd: "I use Prime95 and OCCT for stress testing, at least 8 hours each before I determine an overclock stable." So my 8h ORTHOS+everest burn test was not enough? Or could it be the psu? (vx-450w)



Once again sorry for being annoying and thank you

Your CPU will be fine during the summer if you keep your temperature in the fifties while stressing in the winter.

Voltages can be incorrectly recorded, and they can also fluctuate. Like I said, as long as it isn't spiking over 1.55 you'll be fine for 24/7 use.

Your PSU should be fine, but I'm not as knowledgeable on those as some people here are. I've never used Orthos or Everest, so I can't say how well they will stress test a CPU. My only experience is with Prime95 and OCCT, which work well enough for me.

For your bios, "CPU/NB Frequency (min:4.00x - max:10.00x)" is the setting you will change to raise your NB. I'm not sure which of the other settings, if any, are for controlling the voltage. Don't mess with the HT Link section, and I don't think you need to worry about the chipset section either. I could be wrong though, as I've never owned an Asus board.

Thank you for the reply. You have been very helpful smile.gif

I cant manage to get framework 2.5 for my pc (will try to get it later today) in order to try prime95 and occt. You said CPU/NB frequency is what i have to change. The frequency is a like a multiplier that will multiply with the cpu clock just like the normal overclock? And with what will it multiply?


Once again thank you very much,



Edit2: For my FSB 243, would it mean that i cant go higher than 2430? (max multiplier is 10?). Or im thinking this wrong?

My everest says this:



CPU Properties

CPU VID 1.3500 V
North Bridge VID 1.2000 V

CPU Speed
CPU Clock 3402.2 MHz (original: 2800 MHz, overclock: 22%)
CPU Multiplier 14x
CPU FSB 243.0 MHz (original: 200 MHz, overclock: 22%)
HyperTransport Clock 2430.2 MHz
North Bridge Clock 2430.2 MHz

Memory Bus 810.1 MHz
DRAM:FSB Ratio 20:6

So, is my NB already set at 2400mhz? And what about my timings on the rams?


Thanks

You were right about using OCCT... 30sec after using it i got a bsod... Orthos and everest weren't reliable on my case. Im already at 1.43125v and dont know if ill have to go higher....
