• Overclock settings wont stick
    16 replies, posted
I've been fiddling with my BIOS today and no matter what CPU/memory voltage I tweak my CPU Ghz doesn't move.. I've changed all my settings from auto to what they should be on the left and various other options to disabled or auto (such as calibration and Memory A + B timing PCI Settings are at 100, Temperatures are at stable 30 degrees... I'm not sure what I'm doing wrong or why nothing sticks Specs: Gigabyte EP45-UD3L Mobo Into Core 2 Quad Q9400 @2.66Ghz (Trying for 2.8) FSB = 350 8x Multiplier) 4GB Dual DDR2 @ 420MHz (5-5-5-15) 500GB Seagate SATA HDD GTX 560Ti 1GB Oc Twin Frozr Lian Li 650w 80+ PSU Cheers in advanced [editline]6th November 2011[/editline] bump
Where are you checking the GHz? A lot of the time, the Windows dialog doesnt update. Use CPU-Z to check the clock speed
Im using CPU-Z to check the clock speed and the bus speed's default is 355, the best i can get it to is like 336... so, somethings wrong here?
Any power saving settings on?
nope
You want to be editing the multipliers. On my Gigabyte mobo the clock only raised when using the raising the multiplier - Voltage change appeared to do nothing to the clock but CPU-Z did detect the voltage increase.
My multiplier options are either x6 or x8?
You shouldn't just set a target like 2.8ghz and think you're going to be able to hit it. When overclocking a cpu sometimes it's not up to the overclocker it's up to the cpu what it wants to overclock to. That ram is going to probably be a limiting factor I don't think 840mhz is good enough for much overclocking
But it shouldn't stop me from getting 2.8Ghz, i cant even get 2.7?
In most CPU's you cannot even change the multiplier. Also changint he voltage does not increase your clock, it just makes it more stable. Also I take you are changing the clock via bios? After you ahve increased the FSB are you sure you hit F10 aka Save and Quit and not just Quit?
Im keeping the same voltage as I dont believe i need to increase the voltage to increase it from 2.66-2.7, thats just crazy - and yes im using save and quit and the FSB default is being changed (as default its 350, i've tryed 355, 360 all the way up to about 380 only increasing the voltages a couple of times

Ok... and....?
Try resetting everything to default and then only moving the FSB.
Didn't work
I had this problem, I think in the end it was something to do with the fact my old Gigabyte motherboard only had a 4+1 phase design or something.. (My 1055T could only go from 2.8 to around 3.1 at the most, but past that and it switched everything back to 2.8, like it was at default settings.) This new ASUS board lets me get up to 3.5, but past that and I get BSODs as my memory starts crapping out for some reason (despite being Kingston HyperX..) If you can try another motherboard, do it.
Problem was awhile ago mate, got a new rig now ^^ (4.6ghz quad - 2500k)
