I overclock my A64 1.8Ghz to 2.2Ghz using clockgen. Everything works fine no stability issues. However, when i enable the "apply current setting at start up" in clockgen i start having weird problem. When i cold boot the pc i get the error "no video input" from my LCD. I got to off n power on again then i can get display. When i disable the "apply current setting at start up" in clockgen i have no such problem. Anyone has an explanation\\solution to this??? thanks.

Overclocking with programs such as clockgen is known to cause instability on systems. It is much better to overclock in the BIOS. Check out the Ultimate Overclocking Guide to get started in the BIOS!

I edited your thread title so it might get more responses

The best thing to do is to try and apply the settings that work in clockgen via your bios (if you can). Is CoolnQuiet turned off in bios?

Thanks. Yes, cool n quiet has been turn off. I can't go far if overclock thru the Bios. I thought the oveclocking setting only takes effect when the clockgen is loaded in WInXp when the PC starts. But initial turn on i start to get no video input error. I really cannot understand why....

dude... you say you cant go that far using the bios... well i know for a fact you can

i got a 37% overclock with this board, and i run that speed 24/7

on a side note, what bios version are you using?

 

[Xavier1421]

Hmm, you say a no video error at startup...but does it get into windows with the Clockgen settings? Or does it fail to boot when you attempt to start up with clockgen settings overclocked?

I cant get into windows when initial power up. I need to power off and power on again then i can get into windows. And yes, windows loaded with the clockgen setting.

I m using F9. What about yours?

 

[Xavier1421]

You're running the latest bios. Maybe try and implement the clockgen settings into your bios, might clear it up.

Thru the bios i cant get past 212mhz. I have tried everything like relaxing memory timing, HTT @ 2x\\3x\\4x, memory divider 1\\1.5, 1\\1.6 increasing voltage for the HTT, memory, Cpu vcore. I guess my 2 x DDR400 512mb of memory are crap....

 

[Xavier1421]

But the clockgen settings work at ~245? Odd! If you can boot into windows with the clockgen settings applied, take two screenshots of CPU-Z, one of the main tab and the other of the memory timings tab

[Xavier1421]

Und now for the memory tab

For future reference, you can open CPU-z twice and have two separate windows for viewing different tabs

Asynchronous overclocking with clockgen FTW!

A 166 divider in bios should give you close to the same ram speeds if you bump up your FSB to 245. Drop the HTT(LDT) multiplier down to 4. Or have you tried these things before?

The current setting in Bios now is 166 divider, HTT 4x. But the FSB remains at 200. Only when loaded to windows clockgen's setting will take into effect.
From the Bios using the same setting i cant get past the 212 mark. I cant overclock much from there.

 

[Xavier1421]

That makes no sense that clockgen's settings would work and not the bios settings, unless of course the clockgen's settings are unstable but aren't showing the instability as it has already booted into windows. Have you run SP2004 or SuperPi to 32 million to make sure it's relatively stable with the clockgen frequencies?

"Clockgen is bad Mkay".....

I used it for a short while on my s478 ASUS rig and had nothing but heart ache the whole time....

 

[ocway]

Took ard 36mins to complete while im surfing the net. CPU Temp @ 42-43c

 

[Xavier1421]

Yeah, definitely confused! Try one last thing, run SP2004 for a couple of hours to really stress the system.

I'm at a loss because you appear to be stable, and yet the clockgen settings copied to bios won't boot.

Just noticed something odd. The version of bios shown in cpu-z is F2, but the date matches F9. Maybe a bad flash? Could try to flash to F9 again. At that point, I'm out of input
