Here's to it having peaked in July and August being less. I was trying to do a little maintenance on the A/C... despite the fact I just rent the place, out of fear the compressor would die from having to run constantly. I couldn't live in a house that was 90+ during the day from no A/C. I'm sure my landlord can't turn an A/C repair around in under a day. It was only ~ 90F today... better than the 97-101F days we consistently have been having the last 2 weeks.

That and my poor $80 Noctura has been disappointing me lately... making me wish I'd just used the $25 Xigmatek DK cooler I already had on hand from my LGA 775 setup... or bought into a watercooling setup.

Hey Everyone!

New 3820 owner here. I just came from a q9550 and it is quite a different experience for OC'ing, especially with the R4G. Anyway, I had a few quick questions:

Does chaning the mulitplier turn off all power saving features? I have heard conflicting reports on that. I ask because when I OC the chip in any way, I am locked at that max requency (currently @ 125 x 37).

Does any one know the TJMax for these chips? RT 3.70 has it set as 100, but I have read it is 105.

I am SUCH an n00b with anything newer than P45 so forgive me; Is there a way to achieve a 1866 ram speed with a 125 bclk, or is it just mathematically impossible?

Thanks in advance!

Anyone using Corsair Vengeance CMZ16GX3M4X1600C9 16GB kit (4 x 4GB)? May I know how much you can squeeze from it when overclock?


Rmerwede,

CPU power saving does not turn off automatically when increasing the multiplier. Make sure SpeedStep & C1E are enabled in BIOS. There is a reference of TJMax in datasheet but it didn't stated the value. AIDA64 also reported TJmax 100C. I guess it is 100C.

Mine gets to 9-8-8 timings, with others reduced, very easily. Apart from that, I haven't attempted higher frequencies.

Thanks for the reply Kizwan!

I found out, over at the ROG forums, that even though all the power saving features are enabled, the CPU wont clock down if there is a manual VCORE value. Their suggestion was to to run it in Auto or offset mode. Running it in auto did not seem to help, plus the auto setting was pumping 1.46v @ 4600!!! I am stable at 1.31v at that speed. The offset seemed a little odd to me. My CPU seems to run at 1.05v stock on this board. Since there is no manual VCORE value, what exactly am I offsetting? If I added the voltage I need to reach 1.31v to the apparent stock voltage of 1.05v, then I would need to + 0.260v. This value was well into the red, while a manual voltage of 1.31v is not. So that leads me to believe that one cannot go as high the offset vcore.

IDK... There has to be a way to enable overclocking and speedstep at the same time... stun.gif

As far as I know, it shouldn't behave like that. Run windows "Resource Monitor", click CPU tab & see if any process/service using CPU resource.

Regarding VCORE offset, in layman explanation, you know when not overclock, stock frequency can run stable with stock voltage, so when overclock, to run stable you'll need to adjust the VCORE. The advantage using offset over manual is that when CPU is idle, the VCORE will reduced, which means less operating temperature. With manual, even when CPU is idle, the VCORE still the same & this increase operating temperature. VCORE offset example, let say VCORE=1.33V when under load on default (not overclock), when overclock you need at least 1.38V to run stable, so what you do is set offset to 0.05 & you'll get 1.33V + 0.05 = 1.38V.

What? Manual voltage here on my high clock profiles and the cpu downclocks no problem.

In my experience it will down clock, but the voltage doesn't change, so I don't see a point personally.

I found that my motherboard has two spots to specify a multiplier, one is the turbo multiplier. If I leave the base multi at auto and set the turbo multi to what I want for an overclock, it will adjust the frequency as needed.

I don't know what's up with the colour coding on these values either. I noticed the same thing. As for your question about what you're offsetting, it's the SVID iirc. As you scale the frequency the voltage ID of the processor should scale with it, and that's what you're offsetting.

Higher voltage with no load is better than running full clocks with high voltage all the time.
