THE Asus P5E X38 Thread

[aleiro]

check this out to edit your registry... i have been making windows search and it is ALOT faster...as always results may vary

Man... 2x's the amount of options as before!!! And I'm still puzzling out the options in the 0605 bios

I need some help.On this board i cant get this board to OC my Quad past 3.2ghz stable.But on my PK5-E i was able to hit 3.6ghz 100% and on my Abit IP35 i could get 3.8 stable.But this board has so many bios setting that i cant seem to get them right .I dont really under stand all the PPL voltages and GTL voltage's.

Here are the bios settings that seem to work. Just note that the NB chipset might need more voltage. My NB needs unusually low voltage for high FSB clocks. Try 1.45v to the NB...






These advanced Bios settings really helped me bring stability to the system: AnandTech

CPU PLL Voltage: Scale range is 1.5-3V in 0.02V increments. Stock is 1.5V, and although overvolting can bring increases to FSB limits, we do not recommend using past 1.75V for long-term use.

FSB Termination Voltage: Voltage scale runs from 1.2V-2V. Quad-core CPU overclocking is especially dependent upon VTT and GTL voltage ratios. The max is 1.50V.

Loadline Calibration: Available options are Auto, Disabled, and Enabled. Use "Enabled" for overclocking. This function reduces Vcore voltage sag.

CPU GTL Reference: This setting is a derivative or ratio of the applied VTT voltage. A setting of 0.63x provides the most headroom for overclocking quad-core processors.

Northbridge GTL Reference: A value of .67x generally provides the best level of stability on this motherboard.

I would like to note that this board overvolts the ram so you may need to install AIsuite to check the voltage. My G skill requires 2.1 to run @ 1000mhz and in the bios i set my voltage to 1.96 but in AI it said 2.1 exactly. I havent had a single problem with hangs because of undervolting. Also, i have read reports of burning up memory with this board

Yes, I verified this with my Fluke digital meter with both the P5E bios and the Rampage bios, see post #204:

Special thanks to Karl eller for the post on vdimm points. I used my Fluke 177 digital meter and read the yellow and one of the blue marked readout point from his post.


When I set the vdimm in bios to 2.16v, I get a reading of 2.21v from the multi meter. Then, when I set the vdimm to 2.18v in bios, I get a reading of 2.238v on the meter. And finally, when I set vdimm to 2.2v in bios, I get a reading of 2.25v on the meter. This makes it very hard for those without a multimeter to know the true vdimm.

I did find that my 1.40v vcore set in bios, which loads into windows at 1.38v as shown in CPU-Z, actually is 1.376v when metered while running Orthos.

Thanks again, Ericeod. I can see why you have so many REP! Even though I saw the Rampage hack on XS first, I did refer to your post a bit for the colloquial version:

***EDIT: Is this the latest BIOS revision?

No, the latest version is 0219. It has been shipping with the new Rampage Formulas. But 0207 is the latest bios listed on their site. The link in my post has the latest bios.

Oh, okay. Got it now. I made the mistake of not following your instructions to a T. Thanks again!

And ****EDIT: The latest build of Everest (4.5+) will bring back NB/SB temps (phew!)...

I'm thinking of buying this motherboard for my new Q6600 cpu. I was thinking of going with Thermalright Ultra-120 eXtreme. I've browsed through this thread but haven't seen anyone listing it in their sig. Can I get someone to verify this? And also, are there any issues with the mounting process and etc.?

Thanks
