What did I do wrong in this OC?

[irishdude]

Maybe I'm just stupid, but here is what I got after my first OC

In the BIOS I set the CPU multi to 8.5x and it said it was supposed to be 3.40Ghz, but there it says different stuff 😵

The RAM is at a 1:1 ratio. Also in the Properties tab, it says 3.40Ghz in there. What does that mean.

Someone enlighten me <__<

I'm on a X48 BIOS and I've already been suggested SpeedStep (which isn't in my BIOS anywhere) and also Power Management tools on the comp, and I've had no luck with either.

Edit: It's some sort of power save setting because when I open a game, it goes up to the proper settings. Now just to pinpoint where the setting is 😵

In my bios there is an EIST feature which lowers the multiplier when the cpu is not in use or in very little use. Run prime or any application that uses some of your cpu and I bet that your 6 multiplier will instantly clock up to 8.5x. This feature saves power when cpu is idle or near idle.

Your prop tab reads your default cpu clock and then the latter is your oc clock. You have it oc'd to 3.4

Also, I see 3.25gb of ram so we know you're running 32 bit xp

Lol and it also says I'm running XP a little further up that page. <_<.

Anyway, believe it or not like 10 minutes before I came here I went into the BIOS and changed that, and it's still giving me a multi of 6.0. But yeah, like you said, when I run an app that uses my CPU it goes up to 8.5x. Maybe I should just keep it this way since I don't in fact need the speeds when I'm not running any apps, and I can save power.

In BIOS you need to disable EIST and C1E. C1E is the one that lowers Multiplier, EIST lowers the FSB

 

[irishdude]

Alright thanks. Do you think I should keep them off or is the energy saved not really worth it?

 

[Camikazi]

I've never used them since I like to OC and every time I had them on comp crashed. I also have not looked to find what kind of energy saving they give, so I can't answer the energy saving question.

 

[irishdude]

How did the comp crash when you had these on?

 

[cow_moo]

yeah it's mostly the C1E and EIST I had the same prob but I just left the clocks same and oced the video card instead

 

[irishdude]

I have an ATI 4870, and in the utility that coems with it I can safely OC it to 790mhs GPU Clock and 1100mhz memory clock, and I'm content with that. I want to get another 4870 but I'm not ready to spend that much money yet lawl.

In BIOS you need to disable EIST and C1E. C1E is the one that lowers Multiplier, EIST lowers the FSB

C1E and EIST only lower vcore and multiplier but on different terms. One based on the halt instruction (C1E) and the other based on current system demand(EIST). The FSB in these operations are never affected since you're lowering the multi and vcore already to get the lower clock.

EIST is a more enhance "end result" than C1E. C1E is an either off or on sort of multi underclock where the feature is either being employed or not used based on an idle system. EIST theoretically can throttle a system depending on the current demand placed on the CPU, this is why I sometimes see my cpu stay at 6x multiplier when surfing or using other low demand apps. Also, EIST is supposed to be able to up the multi as the demand increases, but your system needs to be aware of speedstep for this to work.

Hope this helps. Oh and the OP, I could read you were using xp but I also read your system was only showing 3.25. This is because of the limit that a 32 bit OS has in only addressing 4gb total of physical ram.
