Ran prime + folding for i guess 20 minutes and my pc rebooted, so i shut it down for the night, cause i needed the rest.

Will try later this evening with lower settings, going back to 3.3 ghz

Question. I have +/- the same system as Stig, only I have 2x 512Mb Twinmos PC3200. Systems runs idle @ 31 with an SLK900. Can I do same thing for Oc'ing my system? With that I mean ramtimings. Because from what I have read those Corsair sticks can handle much better timings than my Twinmos sticks. ( but hey, they cost double )

Another thing, when I set my mobo to Turbo mode, I can't boot the system. Just have to try couple of times and then POST says "overclock failed, press F1 to enter setup" or something like that. What could this be? Memory problem?

Thx!!

Ps I have latest bios and all latest drivers, hyperpath and hyperthreading are enabled. Os : Winxp pro

that is because your ram can't handle the turbosettings

try to set the timings yourself ( by spd )

Hey.
Well, I've got a question relative to those in this topic, so i thought: why wouldn't I post it here.
I've got Corsair TwinX 512-4000, P4C800-E Deluxe and PIV 3.0Ghz.
Now I went overclocking that beast, to make it even beastier, but I got stuck at 3.54Ghz.
My mem divider is 1:1, but due to the pc4000 memory (weird is that cpu-Z only recognizes it as pc3700, guess its a bug in cpu-Z)
I guess it won't be the memory that blocks it.
I'm gonna try locking up that AGP/PCI frequencies now, but has anyone got any more hints for me how to get further?
Timigs are set by spd (3-4-4), because I thought timings weren't important on i875, so I trusted on the frequency for 100%
Oh , and before I forget: what do de following terms mean in my BIOS:
Performance mode: Turbo.
ICH Delayed transaction.

Lots of thanks in advance,

Bored

PS: if you think this doesn't belong in this topic, pm me or so, and I will delete it and create a new thread

When you overclock your rig for the first time, be sure to overclock one component at a time. You can't be sure whether it's the ram, the cpu or one of the agp/pci components holding you back.

Lock agp/pci and set mem to 4/5. Let us know how high you can get it.

best friend two posts above, you're stuck at 3540 because the cpu has enough, that's the mean overclock on a 3.0.

damn, thats a pity.
Thought I would be able to get higher, because on an allmost the same system from a friend of mine, i pushed that 3.0Ghz to 3.69Ghz.
His system: P4C800 deluxe, PIV3.0Ghz, corsair twinx 1024-3200
I didn't know about the fact that synchronous memory was faster than strict timings, so it runs at the "auto" frequency, but at the strictest timings.

But I'm still wondering what that turbo mode and delayed transaction is..
If anyone would be able to get me out of this,...


Anyway, thanks for all you guys' help.

Performance mode : PAT, enabled by default on Canterwood/I875 mobo's. Increasing memory transfer speed by applying stricter timings.

ICH Delayed transaction has something to do with the southbridge & Raid I think.. not sure , use the power of google
