Seems to be when at full load. Sometimes its not while gaming but doing something else like expanding RAR file or something else where the computer is working.

Did you test with LLC set to lowest or a notch above lowest?

[Mark767]

No, I have only tried Level4. Also, I forgot to mention that this was an older screenshot and the Short, Long and Core Current Limit on the first screen is not 225 but lowered to 150 or 175.

I'm so sorry, I didn't check the screenshots before.

1.336V is most probably too low for anything above 4.5GHz.

For example, mine needs 1.320V at 4.5GHz. I needs way above 1.35V for 4.6GHz so I haven't really chased that goal. you, not necessarily, but most probably will need 1.38V or more, depending on your luck, for 4.7GHz and above.

Also, you can lower PLL voltage as much as you can (might or not help the OC), and as long as the PC POSTs, you don't need more volts.

[Ket]

Generally you need about 1.4v (actual) for anything in excess of 4.5GHz unless you have a golden chip.. which not many do. So, set 1.4v and see if you get a BSOD.

[Mark767]

So how do I get 1.4V using offset? or do I have to use a fixed voltage ?

[Ket]

You can get 1.4v with offset, its not really any different than from using fixed vcore... I personally use fixed vcore though just because my system runs BOINC so the CPU is always at full load anyway.

[Mark767]

So I need to increase the voltage offset to 0.06 then ? (1.4-1.336). And would that be -.06 or +.06 ?

[Mark767]

[Anusha]

First find the required Vcore using fixed voltage method. Once you decide on a Vcore to settle down at, you can set it via offset mode.

[Mark767]

OK, makes sense. And then the offset would be negative (i.e. -.05 or -0.06) depending on how I make out with the fixed voltage?

[Anusha]

OK, makes sense. And then the offset would be negative (i.e. -.05 or -0.06) depending on how I make out with the fixed voltage?

Negative = undervolting
Positive = overvolting

So it's almost always positive.

[Mark767]

OK thanks, strange how I have it at -0.03 all this time and overclocking it to 4.8 (albeit with some BSOD).

[xdan]

Usually above 4.5ghz you must set INTERNAL PLL OVERVOLTAGE - ENABLED.
Also memory above 1600 you could set 1.077v or 1.100v for stabiliy.
Aslo SPREAD SPECTRUM ENABLED.
And LLC best is to set 1 not 4.

[Mark767]

This is getting complicated, would love some screenshots where someone has successfully run 4.8 or 4.9. I had it running at this level for a very long time but was getting BSOD every once in a while so backed off to 4.6 now.

[Mark767]

OK back to trying to push this chip. I have set changed from Offset to Fixed Voltage @1.38, power savings mode disabled. CPU ratio Setting, max Ratio 49. I am running Prime95 and core speed on CPUZ is 4889 but Core Votage is showing only 1.28V....why?

[Mark767]

And just to add to that I have now tried Offset and +0.03 and my voltage in CPUZ is now 1.320 or 1.328 while running P95 on custom using 90% of available ram. So far no BSOD but only running a very short time. Temps are up to 73C.

[Mark767]

OK, I think I am getting somewhere. I had LLC at Level 4 and now moved it to Level 2 and my voltages are going up where I expected them at 1.400 under full load with P95.

[Mark767]

Here are my final results. Overclock to 4.9 with Offset mode at -0.01. Voltage goes up to 1.36 with P95 on Custom and set to run at 90% of available ram. Ran for a few hours with no issues, temps topped out at 89 degrees. For running FSX which is the main program on this computer I can run with voltages average at 1.32 and temperatures in the 60's. So I am happy, not sure if I have a "golden chip" or not but seems like good results.

[Mark767]

One, hopefully final, update. Was having a freezing issue with zero load and reading advice on another forum made some slight changes. Moved offset to -.005 and disabled all of the C-States with exception of Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Disabled
CPU C6 State Support: Disabled
Package C State Support: Disabled

Testing now to see if this problem is still an issue. Running prime 95 with no errors and temps below 90.

Hi, can i use this driver pack with the Z68 Extreme 3 Gen 3?
I`m on safe mode right now after change the cpu cooler.

I was thinking that was a damage cpu or memory but i`m running prime and so far so good.
2 options now. PSU but i only add 1 120 fan or...
The mounting CPU fan was not what suppose to be. So i change it just a litlte. The screws that suppose to be above the MB i did put over it. The thing just dont fit.
Also could be cables... i`m on it but without time to play.


Thinking about format but for sure is a hardware failure.

Edited:
Everything back to normal. Unknow source problem

Small 4.0 OC to boinc 24;7 vcore 1.24 on bios. It droped to 1.136 but still stable, Prime and Boinc.
54C Max on summer of Rio de Janeiro Brazil. My new Spire Thermax Eclipse 2 is the best air cooler that i ever had.

Usually above 4.5ghz you must set INTERNAL PLL OVERVOLTAGE - ENABLED.
Also memory above 1600 you could set 1.077v or 1.100v for stabiliy.
Aslo SPREAD SPECTRUM ENABLED.

Please man, Spread Spectrum always disable. This feature is not designed for the final user.
This feature is for Federal Communications Commission (FCC) tests. Using Spread spectrum the MOBO(any mobo) can pass the test becouse it changes the EMI frequencie so your computer wont make any interference on any other eletronic device.

[Mark767]

I am OC'd to 4.9 and rock solid stable under any kind of load, the more the better. Problem is that at the low end I keep getting freezing even with offset of +0.05. Any ideas?

[Mark767]

I guess not too many look at this thread anymore. Anyway I ended up enabling PLL Overvoltage and reducing the offset to 0.035. Looks like this worked and I have not had an idle freeze since last night.

[Ket]

Idle freezing usually means core voltage is dropping too low when idle.

[TEDY]

where is ERP in BIOS, can't find it.

[Sined]

Woa.. theyre still updating BIOS for the board, nice going there ASRock.
