Everyone with a Asrock Extreme6, probably be good to compare settings.
Got my Asrock P67 Extreme 6 up & running now.Any questions u want answered

Everyone with a Asrock Extreme6, probably be good to compare settings.
Hi Elevon
The back bracket is made of metal and is very very close to a few of the soldered pikes on the rear of the motherboard....
This worryed me big time when i started fitting my 9900 cooler as i must have spend about 30 minutes checking there was enough clearance
But there is enough clearance between the back bracket and soldered pikes..
Thanks for the info,I'm leaning towards the Akasa Venom now for cooler.

Just a thought, what is core current limit in the bios?
I know it has something to do with voltage when turbo is applied but just wondering what you guys have it set to?
Mine is 150 at default, I have tried 200 but still windows would not load

I would keep it at 150 (default) I have seen it pushed too 300 on a board that was testing the Extreme6 beta bios @5.5Ghz
I believe it is the maximum wattage that the cpu will draw upon in turbo mode.
While I was testing I got the distinct feeling the system was more fragile off load , if You follow. Once You got into windows it was solid.
We cannot control Intels Load/voltage ramp and I dropped all settings that would increase load voltage.
I found PLL and Internal PLL did absolutely nothing, drop LL to lowest 5 (gives .01v increase per level) and just work with vcore
Don't forget Lots of memory will undoubtedly need attention to termination/signal voltages etc
Hope it helps
Mine is an Extreme4 with 2500k I have found 4.4ghz to be the sweet spot and it runs X44 multi, vcore offset -0.07v LLC level 5 powersave on, turbo + voltage lowest, internal PLL off, PLL lowest, speedstep on
Gives about 0.928 -1.24v in windows (CPUZ
What settings do you run ?
One thing I dont understand is all this talk of "Turbo mode"... don't I just change the multi to overclock it? What is the difference between "Additional Turbo Voltage" and "CPU Core Voltage" ? And what difference does it make using Offset or Fixed Mode?
Is it LLC Level 1 that keeps the vcore the most stable?

O dear !! not a good idea to be playing with settings You don't understand, We all started somewhere but It sounds like You have not taken the trouble to google any of above !
Just tell Me what hardware You have and I will give You a baseline setting, after which it's up to You.
If I were you I would forget everything you think you know about overclocking the SB cpu (not being sarcastic) and have a look at this link, it tells you everything you need to know to get started.
Once you have a good understanding of what the auther has written you should know enough to take your overclocking higher.

latest Sandy bridge memtest http://www.memtest.org/#downiso
Very much worth running on Sandy bridge setups, not only to catch memory problems but CPU instability (somewhere within it's power phases)
3 full passes should do it and watch for lockups/strange errors, any will indicate You need a few more millivolts on the cpu
Helped me sort out a very strange issue I had
Give it a try

This is my point - as far as I can tell the ASRock Extreme 4/6 is different to the other SB motherboards. No mention is made in the ASRock bios about Turbo Multipliers... this is what I am finding confusing. The disparity between what the MSI/Asus/Gigabyte guides/people are saying and what I am seeing in the OC Tweaker section of the bios.
Also it is very disappointing not to be able to use the windows software to overclock. It makes ASRock look like they can build great hardware but suck when it comes to software.
You can choose to use one the bios own turbo profile settings from 4Ghz (x40) to 4.8Ghz (48x) or you can choose to just enter your own multipliers settings..
Really can't see how it can be made any more easy then this.
I see no need at all for windows overclocking software,
I think it much better to set your overclock in the bios screen and then striaght away you can see if your machine will post & boot with the settings you entered..

Do You actually have an Asrock board ? or are you just weighing them up ?
because if You have and installed the "asrock extreme tuner" you can change everything in windows, voltages,Multipliers, fans etc
Yes I do, do you? If you did you'd know the windows software is barely functional. You can change volts on the fly and fans. But if you change multi you have to reboot. As far as I am aware the other manufacturers manage to have this feature working just fine.
I discovered last night the PLL over voltage option does make a difference. I disabled it and not even the pre -configured 4.8ghz could get into windows.
With it enabled and about 1.52v I can get a two hour stable 5ghz prime running. Little toasty though at about 80c. I am going to try to reseat my waterblock. The reason I went for the asrock was for the pci slots and the lga775 mounting holes to use my existing water setup.

Hi JBod, I think you will find that any windows based tuning software will require a reboot when changing the multiplyer. They are all a bit if a gimmick, best to stick to the bios, or now (UEFI) you have far more control in there, as I'm sure you know.
Your temps do look high, which board do you have Extreme6 or 4?
I have tested mine @ 5+Ghz and never went above 68c with a cosair H70.
Which bios are you using as you mentioned a Vcore of 1.52v?
That would suggest that you are not using the beta bios which allows for higher overclocking, cpu allowing obviously.
You are a strange one ! go back and read Your posts... they came across as real lazy Newbie questions !
At over 1.5v and 80c You are well out of what would be My comfort zone
I got to 5.1ghz @ 1.416 volts into windows an ran super pi 7.563 and winrar bench 4235
As I said before CPU internal PLL was off as I found it to do nothing, interesting You found otherwise.
I have only primed at 4.4 and 4.6 but it was a waste of time for me at for some reason winXP 32bit seems unstable compared to X64 and although it primed ok a Crysis bench crashed it, thinking this a memory related issue was when I discovered the Memtest uncovers any weaknesses.
Because basically we are overclocking "correctly" with Multipliers and lack the full control of low to high power phases we need to compromise so the Cpu does not fall over at some Mid multi/voltage load...that's My analysis anyway
I did notice in Prime the Multi was stepping up and down, I'm sure the Turbo power setting in the bios would stop that if required.
Extreme6, 1.33a beta bios.
Allows for higher overclocking? Because of the PLL Overvoltage? Or something I have missed?
I could just have a relatively poor performing CPU. I can get 4.5Ghz stable with almost stock volts.
In regards to the toastyness, as I said I think I need to reseat the waterblock on the CPU and check the AS5 footprint. I lapped my c2d E6600, I've not heard of any concave problems with SB though so it may not be needed.
I might stump up for a new waterblock as this one is pretty old now.

It was more frustration that the SB is supposed to be easier to do overclocking on and I was finding it more difficult than anything I have overclocked in the last 14 years!
Yea I always go for broke with speeds and volts
I have only ever killed one CPU tho and that was a XP2000+ I was trying to get to run actually at 2Ghz.. there was a gap in the spreader which ArticSilver leaked into I appreciate everyones help with this under-appreciated motherboard!

This is incorrect.
