i dont have any settings for 4.8ghz - i used the preset for that as a quick test. i am trying to overclock manually now but cant get the operating system to boot past 4.2ghz and can only get 4.1ghz stable. just for the hell of it though i will try see if i can get 4.8ghz working in the bios by setting it manually. will post back...

That's what I'm saying, preset ain't going to make the job any easier. Firstly lets get the settings right, manually of course. Follow the guide in my sig but be sure to make these changes:

Multiplier 47/48
Vcore - manual - 1.4-1.45v
LLC 2 or 3 depending on which reduces vdroop the best.
Disable PLL Overvotlage - Enable it if windows doesn't load.

Report back when you have done that, hopefully you should be able to boot into windows. smile.gif

i have been following your guide... i must've spent about 4 hours constant today trying to get the operating system to load at anything past 4.2ghz but it just wouldn't frown.gif

i just went into the bios with my 4.1ghz overclock and started bumping the multiplier up without touching anything else. i got to 6ghz and it was still letting me back in the bios. didn't want to keep going incase i caused damage or something. doesn't it seem a bit unbelievable that i got 6ghz to work in the bios with less than 1.3v? wonder how far that would've kept going....

Does the OS load if you turn on the Turbo 50 setting? If so, what is the clock speed and voltage?

i haven't tried that setting recently but im a bit put off it cos it messes with the gpu: http://www.asrock.com/feature/turbo50/index.asp
i'll go give it a go now though to see what happens!

I am pretty sure it will only try to overclock the onboard GPU not your 6950.

well it didn't boot but i found something out during the process. if i save my settings in the bios and exit, then go straight back into the bios without letting the os boot, then just exit the bios without changing or saving anything and then let the computer boot - i can get into the os. im now at 4.4ghz as i type this. what a stupid annoying little problem that was! so we have some progress again - time to play smile.gif thanks all thumb.gif

Edit: Once i figured out that bug in the BIOS things seemed to be going alright. I had 4.6Ghz looking pretty stable passing 10 runs on LinX (obviously more testing would have been needed), but then i accidently did the order wrong saving settings in the BIOS and things went back to how they were before. So i re-downloaded the 1.0 and 1.10 BIOS's. I flashed the 1.0 BIOS, tried a load of stuff - problem persisted. So I tried the 1.10 BIOS and the same thing. I then took the BIOS battery out for 15 minutes and put the jumpers in the reset position, put those back, booted up windows, rebooted, went into BIOS, tried again but the problem persists. I can now only get 4.1Ghz stable again and can't boot anything higher than 4.2Ghz

This is clearly a BIOS bug - I have absoluely no doubt now!!
Im gonna start looking into the RMA process. Since I only bought this board a matter of weeks ago do you guys think I should send it back to the shop I bought it from or try and RMA straight through ASRock? I'm thinking I might go back to buying ASUS boards again lol.... This is the first non ASUS board I've had since my very first build about 7 years ago and I'm not seeing this as a good sign, although my second to last ASUS board developed a BIOS problem a lot worse than this one (computer wouldn't boot at all), but at least it worked flawlessly for almost 3 years first and i managed to get a lovely more up to date replacement with the warranty smile.gif

So other than a bit of advice on what I just mentioned above I think I can call this case solved!

I have a similar issue but my wall is at 4.4. I have booted at 4.5-4.8 before and ran 24 hours of prime 95 at 4.6 and folded for a week like that and then nada, stuck at 4.4 again. Every once and awhile I have gotten it to boot above 4.4 but 9/10 times it wont boot past 4.4, runs nicely at 4.4 and folds 24/7 but nothing above that. Ill be interested to follow this.

BTW, tried the tricks in the first post and no luck. I don't have the Z68 board so some were N/A but the change settings and re-enter bios and exit without saving didn't work.

well this thread is kinda dead now dude... i came to the conclusion that the BIOS was messed up and am actually just about to buy myself an Asus board to replace this one while i'm waiting on hopefully getting a refund for the asrock board. if you read through this thread you will mostly just find a load of suggestions for overclock settings. its only in the last few pages or so that things started coming to light. i think i summed it all up in the first post after updating it a few times. it was just a strange bug. but if you had 4.6ghz stable and now cant get it to boot then maybe you have a similar problem. im not really sure what advice i can give other than what i've said in that first post :/ good luck with it though man!
