Official ASUS X38 Boards: P5E, P5E3 - Info/BIOS Thread

[rozak]

Any chance someone could reply to my question two posts above please?

Sorry, I cannot answer about rampage formula, but P5E runs without problems with AxeRAM 1066+ (4x1GB 1066MHz 1.90V 5-5-5-18). It runs with no problems with any BIOS I have tested.

[WeldZilla]

Well As some of you know I recommend G.Skill 6400 HZ and have for most of this entire thread. But, many of you have ended up with 8500 mem instead.

Thats fine, what is done is done. You need to be able to run what you have.

I've spent the better part of the day testing my P5E with G.Skill 4GBPQ.

Here is the best way to run this memory

If you are limited to 425 fsb or less the run your NB strap at 333 and your Dram frequency on auto. This will put you on the 5:6 divider. Then you can set your timings manually. I just set my settings at 5-5-5-15-6-42-6-6-6 and called it good for all testing

Here is a view of first 415fsb then 425fsb
again NB strap to 333 and Dram Frequency to Auto

As you can see pi and AQMK3 fare pretty well at these settings.

I was surprised by the fast pi times


Now on my system once above 425 unless I rammed the Mem voltage to it it was time to go to 1:1

Now above 425 to run stable on the 1:1 you need to set NB strap to auto
and your Dram Frequency to auto. Both of them!!!
You can still however det your timings manually and should.
Again I just stayed at 5-5-5-15-6-42-6-6-6 I also stayed at 2.1 in the bios for mem voltage
Next I ran it at 450fsb with no problems at all

As you can see it moves right along at 450fsb
Next I turned it up to 475fsb and again fast and smooth.


So I ran it up to my daily clock of 500 fsb @ 4500mhz to see if it would even boot!! Well boot it did. So I surfed for about an hou. Then I played C0D4 on line staying in the free-for-alls for a little over 2 1/2 hours. Then my son took over and played another 2 hours. Then I spent some time with the neighbor who was wanting some music copied and burned and then agter about 6 hours of running I benched it with out a reboot just to see how it would perform.


Is it as break neck fast as with my 6400hz No but unless you run AQMK3 you would never know it.

Again 425fsb and lower I used the NBstrap to 333 and the Dram frequency to auto. Set your timings manually.

Above 425 I found it best to use auto on the Strp and the Dram frequency again setting the timings manually.

Good luck

hmm which BIOS does you board use? I haven't read through the whole thread as I don't really have the time to, but are many other people having that problem with 1066 RAM at stock speeds?

[godsfist]

Crazy cool dismanatling isn't a problem, I had to do it on a P965-DQ6 I had.

It's not a problem, but I'm not going to pay extra money for extra hassle either when they are basically identical boards

[antari]

I am having issues with blue screens under load. Games are fine, but when I try to run Folding@Home SMP, after at most 20 minutes I get a crash "A clock interrupt was not received on a secondary processor ...". I am sure it is not the processor as I'm running it at the same voltage I always have, 1.248-1.256V.

Does anyone else have issues with 8GB of RAM?

[begrip]

Hi, Can i flash a P5E3 X38, to a rampage or anything else?

All BIOSes I tried from 0401 to 0702 are stable with AxeRAM 1066 at the above settings. I had before normal Transcend modules (DDR2-800) which were never stable at their stock ratings.
X38 boards are picky about RAM. They just seem to love Micron D9s (GMH).

What is the sweet spot for overclocking a q6600 with a stock cooler with good temps

Im new to overclocking but i wonder is it possible to run q6600 at 3ghz with safe 24/7 temps, and how do i overclock it

My current set up is

q6600
asus p5e
4x1 800 crucial ballistix
8800gt
520 crosair psu
vista ultimate 64

here are my temps for stock settings in everest

Mb- 31c
Cpu- 30c
core 1- 44c
core 2- 44c
core 3- 45c
core 4- 43c

what options should i change in bios to achive the overclock and what options should i leave alone?

[xBanzai89]

I'm trying to overclock my E8400 with my P5E right now. I'm having issues with the cpu voltage dropping. I tried looking at one of the pencil mods earlier in the thread, but I have no idea where he put the mark on it. Could anyone point me towards one please . For the record I'm running bios 504 or something like that.

Ok so for the vmod all I have to do is put a pencil mark on the resistor he marked?

E8400 @ 3.915 GHz. This ran stable for a hour on Orthos before I had to stop it. I just can't seem to get over 440 on the FSB even upping the voltages on the NB and other areas. Max temp was 61 C according to real temp (My room is a bit warm due to a heat wave).

I need a check over on the settings I'm using right now:
FSB @ 435
Mem @ 870 5-5-5-18
VCore @ 1.4125 (Drops under load)
CPU PLL Voltage @ 1.56
FSB Terminal Voltage @ 1.38
DRM Voltage @ 2.16
NB Voltage @ 1.47
SB Voltage @ 1.150
LC Enabled
CPU GTL @ .63x
NB GTL @ .67x
SB 1.5V @ 1.6
CD/PCIE spread disabled

Is it true the crayon mod is better then the pencil mod?

[3BABY]

Hey Guys,

just wandering if anyone has flashed P5E3 to any x48 ddr3 variants.. namely P5E3 Premium ?

thanks

[faria]

i'm getting some random blue screens in idle with bios 0702.. anyone having the same issue?

[AceGoober]

Haven't experienced any idle lockups though I haven't been able to get this x3350 past 3.36Ghz, yet.

[lowtcell]

Yep, prime stable Q9550 and 0702 bios and still random blue screens and lockups. Just put the Q6600 back in flashed back to 0602.

can u upload bios 0602 to rapidshare or something please?

I'm testing right now with bios 0601.. see if i get some random blue screens while idle.

[Buggalugs]

Well guys i just dumped my X38DQ6 (dam memory latency and dpc latency problems) for this P5E and so far i am very happy. I have E8400/1066Mhz ram and it booted fine even tho it had an early (0303) bios. Flashed to the 0702 and bumped itup to 3.6Ghz no problems at all rock solid stable and faster/more responsive then the X38DQ6. I have been in the DQ6 forum for a few months so i'm not looking forward to reading this whole thread.

If anyone can post some major tips for the board that i need to be aware of, that would be good.
Also whats the go with flashing the maximus? bios is it worth it?

Oh and my last Asus(P5B-D) didnt have transaction booster. Is it like performance level or static tread on the DQ6??

[VinnyG]

No it's not the problem, it's their pathetic bios.. but as I said, no problems whatsoever with the Gigabyte.. ahhh stability, it's good to have you back!

Granted my P5E has been pretty picky on quite a few settings, its just a matter of learning what it likes and then it just works like a charm, BIOS 502/601 were pretty good for me, BIOS 605 is the one I am currently using and it work pretty damn well. Apart from the somewhat infrequent board squeal I get from some stressed capacitor during Full load, which only happens in certain situations, everything is working great:P

Im currently using PC2 8500 Crucial Ballistix RAM using the FSBRAM ratio of 5:6 so 420Mhz:504Mhz in my case.

The thing I noticed is that in order to run the FSB Strap of 333Mhz with a PL of 7 your NB volts need to be in the 1.51-1.55 volt range.

It has now been 6 months since I stuffed my E8400 into the socket on my P5E. I have run it continuously at 4500mhz and higher everyday of the week since. I only run on the 9 multi and as high as 531fsb I have ran 2 x 1 gb sticks of G.Skill 6400 HZ mem. I have run 2 x 2gb sticks of G.Skill's PC 8000PQ
I can only run it 1:1 @ 5-5-5-15 as you see in the post above. I am currently running 4 sticks of the 6400HZ and it runs great on the 5:6 at only 2.06V. This wolfdale has never seen less than 1.54V in the 6 months I have owned it and it has not lost one bit of speed. It runs flawlessly day in and day out. I read in a Rampage thread that this board was inferior. I just found it amusing that the person that wrote it was running a Q6600 at 3200mhz stable ands was so dam proud of it.
I ran a Q6600 for quite awhile on this board too and it was stable @430fsb
Well here have a look. Back then I was running 2X1gb of G.Skill 6400HZ I was also running bios 502 back then.


I now run 601 and have since I installed the Wolfdale 601 works better for it.

Here is today's shot just to let you all know I am still kicking along at my posted daily clock.


This has been for me the absolute finest motherboard I have ever built a system on since I started this stuff in 1979.

I have a P5Q Pro that will be here tomorrow. I will know more soon how it measures up. It too will be running an E8400 but, it will be air cooled like my P5KE wifi that also runs daily at 4500 mhz ah but that is in another thread....

Kepp tweeking them feelas the power is there. I have done no mods of any kind to this board. I never found them necessary.

Great to hear WeldZilla

[lowtcell]

Good: Currently, running Q6600 437x8 prime stable on bios 602. Will run 437x9 also, but needs too much vcore for air. 2x2GB G-Skill DDR2-1000PQ @ 524.
Bad: Q9550 430x8 and 430x9 is prime stable (4+ hours) but I get lockups and reboots out of the blue even with RAM at 1:1. Tried bios 605 and 702, neither fixed the issues. 602 gives me a "unknown CPU type" message.

With BIOS 605 try higher memory voltages and/or losser tFRC, you can also play with the Transaction booster/Ai clock twister settings to find out whats goin on with RAM stability.
