a little bit of overclocking help please

Odd. Make sure all the settings are correct.

And yeah do the x2.5 memory multiplier and 5-5-5-15.
 
tried that too -no success. Also tried timers on 4 4. 4 12 but failed and took 4 attempts to boot to default. Do you know of any good cliff i could jump off!!!
 
No luck either. It's very disappointing but I cant continue to pester you at this hour of the night so thanks for all your input Ill try again tomorrow jos
 
If it's no better in the morning then select the Load Optimized Defaults option from the main BIOS screen, save, reboot and re-do all your options from all the menus.
 
Have you re-set the memory timings to SPD? If so then try the memory multiplier at x2.0 to take the memory completely out of the equation.
 
Thanks cob did that timimg on auto, multiplier on x2.0. It gave 3 loud bleeps during boot and reset to default! could it be anything to do with the dtr overvoltage control which is+o.300v which is showing pink? a shot in the dark!
 
The memory voltage? No changing colours is normal.

Try CPU Voltage Control on 1.4000v.
 
Thanks fingers crossed now!Temps have gone up to 53 hope thats the norm How long will it take to run this or how long will i keep an eye on it? i'll let u know how it goes Needless to say id never have got this far without you thanks again
 
No problem :)

Try to let it run for 8 hours. That will usually find any problems. Your temps are low enough to let it run without keeping an eye on it, but check every hour or so in case it has found an error or has rebooted the PC. If it does find an error than just up the CPU voltage to the next notch and try again.
 
Hi Cob back again . Orthos has run now for the 8 hours seemingly without a problem Temps have stayed around the 50-55mark. If there are any faultswould they have shown up on screen. I'm really delighted and please tell me what to do next. thanks jos
 
Good to hear :)

If you want to overclock it as far as you can then set the memory multiplier to x2.0 to take the memory out of the equation, and raise the FSB to say 356mhz to get 3.2ghz. You'll probably have to raise the CPU voltage to atleast 1.425v to get that. Also set both the FSB overvoltage and MCH overvoltage to +0.1v.

Then it's just a case of upping the FSB, adding more CPU voltage as you need it. I would run Orthos every 200mhz (3.2ghz, 3.4ghz etc), remembering to keep your load temps below 65-70c.

You'll probably find that 3.5ghz is the very most you can get, whilst keeping temps within range. Once you get over 3.2ghz you'll need bigger and bigger jumps in CPU voltage to get stable.
 
Thanks for getting back. Its booting up ok but hesitates twice before doing so. Is that significant or not? My goal was to take it to 3 as I use this one mainly for rendering video work and I dont want to bottleneck. I do intend to try soon to build and overclock another one to its maximum for games. Does this one need to be tweaked in any way now to get me running with video? (I ran orthos last night for 12 hours no probs.)
Does anything need to be altered on the bios mainscreen menus which are not familiar to me ? Once I get this ratified I am ready to roll! cheers jos
