EPP

[remotehugger]

I have the Gigabyte MA790GP-UD4H mobo that has the EPP option in my bios. My memory is OCZ DDR2 PC2-6400 / 800 MHz / Platinum XTC / Enhanced Bandwidth / 4GB Dual Channel with EPP also. Should i enable my EPP and if i do how could i tell if i was gaining any performance? I already manually set my timings to 4-4-3-15 which are the specs from OCZ's website. I just dont know how i would tell if i am getting any extra performance from the EPP. Does anyone have any experience with this?

If you manually set it to the EPP timings, then you'll gain nothing setting EPP in the BIOS.

OK. So basically thats all EPP would of done is set it to the correct timings ? They were originally being read at 5-5-5-18 but i put them where OCZ said they would run. Oh well. Thank you for your help

Although you have adjusted the primary 4 settings to what the EPP spec that the memory shows, the EPP settings go beyond the primary four settings that you have changed and should (in theory) should be able to offer more than just changing the primary 4 settings. To better understand this you might want to read the following 2 articles...... http://www.legitreviews.com/article/345/1/ and http://www.simmtester.com/page/news/showpubnews.asp?title=A+Quick+Look+at+Enhanced+Performance+Profiles+(EPP)+Memory&num=151

Thank you. They are informative and a little over my head at the same time. LOL. I do only see mention of Nvidia SLI boards. I saw a slide that showed the 790 chipset so do you know if it is compatible? I do have the EPP option on my Gigabyte board but its crossfire not sli.

EPP will work as long as the BIOS supports it.

Thank you. I turned it on and it put my memory up to 420 Mhz with 4-4-3-15 timings. So i put them at 4-4-4-15 at the suggestion of OvrClkr and it jumped to 430Mhz and ran memtest to 100% coverage with no errors. Very cool
