Ohhhh lovely, I so want one...

such a beauty huh

[M40TURBO]

Oh yeah, hope she works out. Just as well as the older ud3p. Or better

[vodka3dg]

nice set-up sergio pushing the limit already??

nice set-up sergio pushing the limit already??

thanks vodka will do for sure lots of fun awaits me

[Leeghoofd]

You need to stay sober for Valentino, no booz for you !! Keep the head clear :p Hope she performs good mate... let's hope the pretest settings work out for ya

ok all you OC'ers im finaly working on a OC on this new mobo,(ga-ep45-ud3p) i got it running 3.83ghz with next to no major adjustments. but trying to take it to 4.03ghz it wont pass more than half mem used in IBT. here is a shot of what i have set in my bios.

Just some suggestions.

[beginer1]

hi mates! A lot of users told me aboout this mobo is best choice for me. Now i need some advices to OC 3.8-4GH for gaming rig 24/7.

MB: GA-EP45-UD3P (rev. 1.6) bios FEa
CPU: QX9650 unlocked Rev C0 with air cooling
Dram: 2X4096-8500C5DF Corsair 1066 Mhz 5-5-5-15
OS: Win 7 64bits

for start:
Advanced Settings
Limit CPUID Max. to 3.....................: Disabled
No-Execute Memory Protect.................: Disabled
CPU Enhanced Halt (C1E)...................: Disabled
C2/C2E State Support......................: Disabled
x C4/C4E State Support....................: Disabled
CPU Thermal Monitor 2(TM2) ...............: Disabled
CPU EIST Function.........................: Disabled
Virtualization Technology.................: Disabled

is ok to disable all?

bios FEa is best for OC?

[In-Fluence]

It's ok to disable all those yes. As for FEa, I don't think it's much better than the others, if at all. I'm having more trouble getting stable with this for some reason, but then again, I did do a quick rebuild.

[cincyrob]

thanks NoGuru. ill give those a try today and see what i can do. like i said i dont think there will be any issue with this CPU going higher, its just getting the mem zoned in.

No problem. I posted this in another forum. Just thought some of the new comers to the board might like it.

So here is the basics.
MOTHERBOARD VOLTAGE CONTROL

Load-Line Calibration: Disabled you will have significant vdroop/drop in vcore. Enabled will decrease vdroop/drop. This will always be scrutinized if it's safe or not. I use it up to 1.45

CPU Vcore: Voltage applied to CPU at various speeds to achieve stability.

CPU Termination: aka FSB voltage, keeps your system stable at higher FSB speeds. Higher FSB=higher FSB term

CPU PLL: This helps you boot into your operating system at higher bus speeds. Typically runs between 1.50 and 1.62

CPU Reference: aka CPU GTL Ref, GTL Ref voltage is derived from the Vtt (vFSB) voltage. The GTL voltage is a certain percentage of the Vtt so to set it you use a multiplier (eg: 0.667x) which means the resulting voltage is 0.667x (66.7% of) the Vtt voltage. I will post a link http://www.xtremesystems.org/forums/...d.php?t=202292

MCH Core: aka North Bridge, This is directly related to you ram. The more ram installed the higher it will need to be. Will help stabilize when there is a FSB increase.

MCH Reference: Just like CPU ref, it will change or scale with FSB increase.

ICH: aka South Bridge, 1.1 should be fine, but the more hard drives or RAID the more volt's you need.



Make sure you read the sticker on the side of your RAM and manually set the volt's and timings. Like 2.1 volt's and 5-5-5-15.
Just remember, after your CPU is stable you can go back and decrease volt's to your ram and tighten timings.

If you have USB mouse and keyboard, Enable Legacy Support in BIOS to use them.

Advanced Bios Features:

Limit CPUID: disabled
No-Execute: disabled
C1E: disabled
C2/C2E: disabled
CPU Thermal Monitor: disabled
CPU EIST: disabled
Virtualization: Enabled (this can be disabled safely)
Initial display: PEG


Here is a guide to get the BIOS in it's best shape

Do a CMOS reset and then load Optimum Defaults in this way
CLEAR CMOS
Shut down--unplug-- hold start button in for 10 sec--short the CMOS pins in lower right corner of mobo for 1 minute using a flat screwdriver--plug back in-start--

Load Optimum Defaults--Set PCIe to 100--Set ram timings-- setDRAM voltage--go to Integrated Peripherals-enable all USB settings(they are at the bottom of the page)--go to Advanced BIOS Features,init display-select PEG
Also the boot order will need attention

This will get your BIOS in it's best configuration.

Thanks dennyb and Marsey99 for help on this.

@ andressergio - Nice board mate, congrats! Will be pulling some nice benches with that for sure.

RAM question...can anyone tell me which is going to OC better...the G.Skill Tridents 1200s or the G.Skill PI 1200s?

I don't have experience with the tridents but the PI's are great.

I don't have experience with the tridents but the PI's are great.

So you have the GSkill DDR2 1200s, what are your results?

http://www.overclock.net/intel-memor...0-pc29600.html

Thanks alot for the link...very helpful, acoma andy is extrememly knowledgable with RAM. Im still really torn though between the 2, it seems like the GSkills will get you higher OCs though but at higher voltages.

viper the PI9600 the old ones with old HS are awesome can take 2,5v without heating

1300 on mine

check also my 5005 with the xeon are with the PIs...

yeah the ones with the gray heatspreader? Unfortunately they arent selling the ones with the grey heatspreader...but I think the new revision should OC about the same.

[gergregg]

1260 PL8 5-5-5-15 2.2v and never really tried further.

[andressergio]

1260 PL8 5-5-5-15 2.2v and never really tried further.

yes on ASUS i did 1200 CL5 PL7 2,0V...on Giga needs more volts but i did 1300 CL5 on 2,4 at high CPU speed PL8

amazing mem
