Just added a E8600 3.33 and want to overclock

Oh, you upgraded from an E8200. Now I know why your multiplier is sitting at x8.0.

I'd be careful overclocking with the PSU you have. I've never heard anything good about it. I'm sorry, but I know that I would want to know.

I need fsb #s to try.

The multiplier is jumping all over the place 6, 8 , 10 .

I'm not comfortable trying to overclock with this PSU powering your system (the LSP unit). If this particular PSU fails due to overclocking, it could kill something in your system, or even your entire system. At the very least, it will probably make both overclocking and achieving stability noticeably difficult.

Still, disable C1E (or Enhanced C1E, or whatever it's called in this BIOS), and disable Enhanced Intel SpeedStep Technology to get started so that it stops dynamically adjusting the multiplier like that.

To calculate what your overclock will be based on the FSB, divide by 4 and multiply by 10. For example: 1333 divided by 4 multiplied by 10 is 3.33 GHz (you may need to do some minor rounding).

Oh man, I don't know if I would attempt any overclocking at all because if I go by this, then you're already cutting it very close at stock:



Their power supply pulled 396W from the wall outlet with two 9600 GTs running Oblivion at 2560 x 1600. If their PSU was 80% efficient during this power draw, then their system was pulling 316W from the PSU during this test!

Your PSU has a +12V capacity of 360W. Here's a breakdown of how a PSU's power is distrubuted:

On PSU Voltages

So really, I think you're in need of a larger +12V capacity, not to mention a higher quality PSU. This PSU is actually a low-quality unit and with a +12V capacity of 360W, it's really just a low-quality 400W PSU. It doesn't look like a safe situation for any overclocking to me, I'm sorry.

Ya i have to go in and figure that out. I wil be happy with the 3.33 GHz if I can get it to stay there.

Oh, then all you have to do is change the multiplier to 10. If you want to overclock, then it would be beneficial to disable C1E and Enhanced Intel SpeedStep Technology because these two features can get in the way of overclocking for technical reasons I don't know how to explain. When staying at stock, they should be enabled so that the CPU can do what it's designed to do properly.

As long as the multiplier is at 10, everything will work perfectly and you will never see or feel a performance loss due to the dynamic changes you're seeing which are enabled by having C1E and Enhanced Intel SpeedStep Technology turned on.

The Ultra 550 LSP is that bad ?

Yeah.

It's probably ok if you don't overclock, but it's still not delivering clean and stable power which has the chance of being a little bit harmful in the long run.

That gadget is not showing the actual clock speed. It's just telling you that it's supposed to be a 3.33 GHz CPU. CPU-Z is telling you what's really going on, and it's showing that you have a multiplier of 8. Multiply 8 by 333 and you get 2,664 which is 2.66 GHz which is exactly what your E8200 was at. The E8200 has a FSB of 333 and a multiplier of 8.

This BSOD could be the result of not enough power. I'm not sure. Try leaving both C1E and Enhanced Intel SpeedStep Technology enabled and only change the multiplier to 10.
