EP45-UD3P Bios settings

[kali65]

Hi Lsdmeasap & Masters,

I've just built up my new rig with the following parts:

1.EP45-UD3P mobo
2.Intel E8400 E0 processor
3.Corsair TWIN2X4096-8500C5D
4.GV-485OC-1GB
5.Gigabyte Superb720 PSU
6.Seagate 500GB 7200rpm sata HDD
7.Deepcool Killer Whale CPU Cooler

Note 1: i'm looking forward to reach 533mhz x 7.5 for my cpu so i can make it 1:1 with my dominator @ stock timings. Your advice on bios settings is much appreciated. Thank you.

Best regards
kali65

Re: EP45-UD3P Bios settings

Tried 533Mhz x 7.5 @ 3.99Ghz with Pi @ 32M with success but failed Orthos & Prime in few minutes. Wonder whats wrong with my settings.

Re: EP45-UD3P Bios settings

hi lsdmeasap, couldn't get stable with 533mhz with the settings, i think i'll give 444mhz x 9 = 3996, any recommendations? btw 1.4vcore shows 1.376 in cpu-z

[Lsdmeasap]

Re: EP45-UD3P Bios settings

Hmm, for 444 FSB you can use 2.00D ram speed, and use Much tighter timings (444-12 or 544-12)

You should not need more then 1.34 or less for 4Ghz, what Vtt were you trying? I guess, try what you are mentioning and if you have issues post me what you used fully that fails and I will advise

Re: EP45-UD3P Bios settings

I have my Gigabyte ep45-ud3p running at 533Mhz with an e8400 (4Ghz, 7.5x) with the RAM 1:1 (DDR2 1066).
It took a lot of tweaking, but its running rock solid.
The voltages and temperatures are all within sane limits.

http://temp.bhmm.net/533-4ghz.jpg

I did the voltages manually based on what I read online.
Had to bump the memory controller voltage a bit (to get the PCI-E working fully), and had to add some CPU clock slew.

If you want me to post my BIOS settings let me know.

Re: EP45-UD3P Bios settings

Thanks for posting your info/tips for others, and mentioning that you can post your settings for others.

Might as well go ahead and do that as it may help someone in the future. Grab a template in my signature and post your settings anytime you have a free second.

Thanks!

You will probably want to slowly increase the voltage/clock slew/clock drive until it becomes stable.
For me, it passed prime95 and intel burnin test, and plenty of gaming.

The mobo / mch (northbridge) temps seem fine even with the voltage bump.
Probably because of the great heat-pipes on this board.
When the voltage wasn't high enough, or there wasn't enough clock slew/drive... My ATI driver would only come up with a generic driver ( no high-res or 3d ).

I tried > 4Ghz, but it seemed the voltage/temps I would have to push to make it stable were out of my comfort zone.
Don't blame me if you destroy your machine!
