Intel speed step..?

[Torres]

I have an Asus P5Ql pro pared with a HD4830 and 2GB Kingston (not the cheapo stuff) anyway, my 4830 is overclocked to 650Mhz core and 950Mhz Memory. Very nice. My CPU is overclocked to 3.56Ghz from 2.5Ghz, very nice also. However I am trying to disable intel speed step and cannot find it literally anywhere in my BIOS. It's not under >Advance > CPU configuration either.

The BIOS is American Megatrends which I find a bit harder to use then Phoniex, oh well. I have seen the option to disable intel speed step before but I cannot hunt it down in my bios.

Help would be fantastich.

Your motherboard chipset and CPU are compatible with Intel EIST (Enhanced Intel Speedstep Technology). It reduces the processor multiplier and hence power consumption when computer idles. To turn off:

In Control Panel, click on "Power Options"
Under "Power Schemes" click on "Always On" then "Apply" and finally "ok"

In your bios, it usually appears as something like "Intel EIST". Click on Disable. However, Intel do not mention turning off in bios, only through Power Options.

Many people (including me) have found that turning off this feature makes no discernable difference to the speed of the computer as the processor will resume normal speed as and when required. I expect some will disagree though!

It will be in the BIOS as EIST and/or C1E. I would leave it on though, no need for the CPU to run at silly speeds when you're just browsing the web and that :)

Torres, if you can find time, mind posting a score to our benchie at stock graphics clock?

I'd like to see what the E5200 can do when thrashed! :p

Hello, I am back. I found the problem was when I changed the multiplier the option of IST dissapeared so I'm guessing it was automatically disabled. I would quite happily post a benchmark with the thing at 3.75GHz..

Do you mean that graphics cards arn't allowed to be oc'ed?

As long as you post scores with details of CPU and GPU overclocks, I don't mind how you do it.

The HD 4830 overclocks very well, as I understand it.

But to compare results fairly, details matter. :D

Ok cool. I put my cpu back down to 3.2Ghz cos of some mysterious bsods...:p Yeah the 4830 is a wonder of a card, somehow the memory gets up to 1Ghz from 800Mhz, not bad for £90! I am downloading the bench marking program now and looks set to take a long time. I'll look at getting my cpu at 4Ghz with some more juice and I'll post up my score.

Just a quick question, what sort of FPS can you get (and with what settings) from the 4830 on various games? (I assume you use it for high end gaming)
Thanks

COD4 maxed out at 1440x900 will give almost a constant 75FPS as will COD:WAW unless theres a huge explosion or you stare into fire, Crysis at the same resolution gives about 30 with no AA and settings on high however it goes all over the place, FIFA 09 can be maxed out too.
