OCCT failed but prime stable???

[cuti7399]

Hello,

I have this setup which prime stable for 9.xxhrs but OCCT failed. Should I worry about it? Also, I set cpu voltage to 1.5v in bios but smart guardian says cpu vcore is 1.39v. Which one is right. Thanks for all the help

DFI ultra-d
opty 144 @ 310x9 1.5v
2x512 pc3500 kingston 2-3-3-7
500w modular antec sp
raptor 36g
evga 7800gt

Well, if it fails at anything, then it isn't a stable overclock. At least that's how I see it. And since you're using an Antec power supply, more than likely, the 1.39v is correct. Try downloading SpeedFan and Motherboard Monitor, and see what they say, as far as your cpu voltage and your rails.

 

[TrueWisdom]

Does it fail at the same place or the same time, every time? Pay attention to the failure you get--it might be a bug.

 

[cuti7399]

it does failed at the same time and place so maybe it's a bug???

1)Antec SP500 can only give a max of 25A on +12va line @ 25C, so it is a useless power supply and not exactly meant for overclocking.

2)My CPU at 1.425V, passes Prime 7h 58min, fails 3d mark 06 and 05, but passes super pi 32M as well
at 1.4375, passes 3d mark 06 and 05 and maybe 01se as well, but fails COD2 demo
at 1.45V, passes COD2 demo as well

Your PSU or motherboard may be undervolting the CPU. Try upping the voltage to 1.55V or even 1.6V (safe limit is a bit over 1.6V) and see if it is stable with more voltage. Or decrease the HTT and try the test again.

 

[akshayt]

IMO safe limit is defined by:
1)Temperatures
2)Ususually 1.5 or lower should not cause a problem, going above that MAY NOT CASUSE A PROBLEM but MAY NOT BE FULLY SAFE either, a risk I would say. But keep temps in control.

 

[996GT2]

You're saying any voltage over 1.5V isn't safe for testing purposes? When Anandtech tests motherboards/CPUs, they frequently go over 1.5V in overclocking tests, sometimes nearing and even exceeding 1.6V. I have run my CPU for 10+ hours in Prime95 at 1.55V and nearly 3.1 GHz, and nothing happened to the chip...even on the stock AMD heatsink, 1.55V is more than safe for testing.

will an antec tp480w 20pin atx be a better?

 

[aldamon]

You think this is bad? When stability testing my E6300, I found a speed where dual-Prime and gaming was unstable, but ORTHOS ran pefectly. The kicker? ORTHOS supposedly uses the same source code as Prime! It's just an updated GUI with built-in multi-threading.

So, yes, you should worry about OCCT failing.

I would just raise the cpu voltage (vcore) .05v first. If both your power supply and your motherboard are undervolting, that may be all that you need. Don't worry about what you set the voltage at in the BIOS, go by what the cpu is actually receiving.

And you never told me what SpeedFan said your rails are, specifically the +12v rail. If it's below 11.70v, you'll definitely want to replace your power supply. This would be a very, very good replacement: OCZ 600 watt GameXStream though this one ought to give you enough power, for less money: 500 watt Enermax Liberty.

Soory but what is OCCT? I know what prime is but not OCCT

Cool thanks for the info Aldamon

Cuti,
what kind of prime test did you run? Blend, small fft, large fft? If you did just the cpu stress test, it does not test your memory.

OCCT i think tests both the memory and the CPU, your cpu might be stable and you might have unstable memory clocks.

[cuti7399]

i think the memory might be to blame. I'm using the divider at the moment until i get my mushkin pc4000 back. I ran all 3 kind of prime test and none of them crash.

It's SP2 500 if you read more carefully (modular???). The SP2 has 36v combined on two 12v lines, a very powerful psu. I had an Opteron 146 @ 2800 MHz and now have an X2 3800+ at 2620 MHz using the SP2. (That is with 2 hard drives in Raid 0, and two Sli'd 7800 GT's)

This is a great modualr psu for the money.....

 

[cuti7399]

well, just bought a ocz 520w. I'll see how it goes and post result. Thanks for all of your advise

 

[cuti7399]

installed ocz psu, same problem???!!!!

You are so full of misinformation it makes me sick. :frown:

You have likely contributed to the OP's decision to purchase a new PSU, something he did not need to do, as his latest post confirms.

You don't even know how overclock yourself, as evidenced by your threads in which i attempted to help you to no avail.

Please either do not post, or at least do not post unless you have some knowledge on the topics on which you are speaking of.
That pretty much means do not post.

I have seen far to many misleading posts from you that people are actually believing, since they don't know the FUD you started spreading here all the way from your X1900XTX being crap threads to your stolen overclocking guides, & whatever else.

 

[n7]

OP, what RAM divider are you using?

You don't state that.

I suspect the issue in unstable RAM from the sounds of it, but it's possible it's CPU, as 2790 MHz isn't exactly a small OC.

BTW, unless the applications, games, etc. are unstable, i wouldn't get too paranoid about OCCT failing.

 

[myocardia]

Cuti, you never said what RAM you're using, or has your Mushkin come back from RMA? If so, which type is it? These Ultra-D boards have to be tweaked for each and every type of RAM, to be stable, like all of the other DFI boards. It most likely has to do with your DRAM Drive strength and/or your Tref settings. Post back with the exact RAM you have, and I can tell you the settings for it.

It's a good thing no one cares about your opinion.

 

[nyker96]

oCCT always fails before prime95 for my OCs as well. Usually I have to have both stable to let it go. I have to say I would worry if one of them can't pass, you could get that error at times.
