MMO-Champion Overclocking Leaderboards

[Xuvial]

For me it's 1.3V for 4.5GHz, but when I want to go to 4.6 I need 1.38+V (haven't really tested how much exactly). Imo the extra current and temps are not worth the minimal gain. Maybe I'm doing something wrong, maybe I just have a strange chip :P
I'm going to look into it when I have more time, probably in a few weeks.

Nope, all chips do this to some degree. It's just some chips' exponential curves are steeper than others...the 4.6 to 4.7ghz jump is what requires my chip significantly more vcore. For me it's about finding the sweetspot between temps and performance, atleast till I get a WC setup.

Oh well, maybe I can get 4.7GHz with 1.4. If not, I'm staying with what I have now. 0.1V and the additional 10C+ extra is not really worth 0.1 GHz :P

Here I am sitting at those extra 0.1 GHz and boy do they make a difference. WHEW! The internets is so fast that I need a slower web browser in order to cope

When you overclock and mind your voltage, what's your load line calibration set to?

Going from 4.6 to 4.7 makes my ESET Smart Security fail at startup because the computer hasn't gotten the service started yet. >_>

Mine's usually at Extreme or Ultra.

[OmnitronDefenseSystem]

Wait.... it needed 1.4+volts to reach 2.8 GHz? PLEASE tell me that's just default...

Sweet deal! Watch it for like the first 20 minutes just to be sure your cooling is working properly and what-not, don't want it bursting into flames while you're asleep. Boy I'd feel shitty for being the one prodding you to do so. =/

...Woah, why is my CPU's voltage so high? Is that normal for the phenom ii x6? Never touched the voltages, is that the default? Now I'm all worried that that is why my temperatures have been kinda high.

Higher voltage definitely would contribute to higher temps. Do you know what your CPU's temps are typically?

kinda my point, running prime 95 for this test was only to get cpuz to show your system under load, not to show off your stability, so if he onyl runs it for a minute that's long enough for the purposes of the thread

Doing it longer though can really show you got it stable. But hey, whatever you want to do is fine, I'm just one for making sure it's stable. I think Fuzzykins kind of wants the list of overclockers to also be where we know they are stable at that clock and 2 hours in Prime won't crash the computer. I don't know how long my computer was doing Prime95 Blend last night before it BSOD'd but I woke up today and came down and had a BSOD. So, I upped the voltage to a whopping 1.35v for 4.5GHz now, but as for right now, not posting anything till I know for sure it's stable.... Going to render some video footage now!

Lookup the event viewer and it'll tell you what time of the BSOD and the reason. I wouldn't just straight up the vcore unless I found it was a 124 error code...but maybe that's just me.

It was 124, I SAW IT ON THE BSOD. But you know that one guide from overclock.net that I think you, or maybe Asmekiel posted, said 124 means you should up the PLL voltage.... or down it. Idk, I just put that thing back on auto.... the PLL voltage no one ever talks about and I'm uncomfortable fucking with.

/thumbs up on the 13 hours running Prime! Nice job!

Well some systems reboot after the blue screen and you didn't specifically say 124 error code :P.

I would just increment the vcore another .05 and try again. And I haven't done anything to my PLL's or any other options in MSI's board, just changed the vcore, vdroop to low.

[Fuzzykins]

Oh jeeze. O.o I forgot all about this. I'll get around to updating it sometime this week.

Yeah I upped the voltage by .005. :P It is now 1.35. =S

I knew I'd get a bad chip, I'm never destined to get the best unless I pay for it. LESIGH.

Video rendering in WMM is going fine, temps are fine, and if my memory serves me right, I started the blend test last night oh around 3am? Looks like it didn't crash till almost 6am. 3 hours, not too bad.

Which will become next week.... and then the week after that.... and then the week after.... no I'm just kidding. :3 I might update soon'ish though for 4.5GHz.

Tuning down PLL voltage (auto = 1.8V for me) to 1.75 made the last bit for perfect stability on my overclock. Also it lowered temperature, both idle and load.

Yeah, I'll have to read up more on it. It's I think around 1.79-1.8 atm. =/

[Fuzzykins]

Done. That was really intricate and annoying work. T.T Message me with any errors. Also, there are a few people I didn't even bother with. Those would be the people who can't follow format.

I've never heard of a 0x124 referring to PLL voltage. On Sandy Bridge, a 0x124 is either QPI/VTT or vCore. You have 16GB of higher-than-stock-speed RAM. I wouldn't doubt you need your VTT bumped up slightly (1.09-1.12v or so, default is 1.05v, max is usually stated to be "under 1.2v"). Also, remember that Sandy Bridge doesn't like the difference between VDIMM (RAM voltage) and VTT to be more than 0.5v apart. So if you have 1.65v RAM and a default 1.05v VTT, it could be causing issues.

As far as PLL, I'd suggest enabling PLL Overvoltage and then lowering CPU PLL to 1.750v. That's been the best average stable point for PLL from everything I've read. It's also my current setup.

Thanks for that. Yeah I did make sure to have the VCCIO and RAM voltage .5v apart or w.e. RAM is 1.65, the VCCIO is 1.15.

Maybe I'll work on this later, I really need to eat though... x_X

1.15v is really creeping up on the VCCIO (VTT). I'd contact your RAM manufacturers and see if the RAM will operate properly on 1.5v (some will, some won't). If they say yes, I'd try RAM at 1.5v and VCCIO at 1.10v or so.
