***OFFICIAL Asus P5K-E/WiFi Thread

[cipher7]

I'm trying to get a stable 3.6ghz clock on my Q6600 and have been trying various CPU voltages to achieve this. Here are my results so far:

vCPU - Prime95 Result (Highest core temp at end of run)
1.3875 - Core 3 error after 1 minutes (n/a)
1.4000 - Core 3 error after 2 minutes (n/a)
1.4125 - Core 3 error after 6 minutes (n/a)
1.4250 - Core 3 error after 2 hours (65)
1.4375 - Core 3 error after 3 hours (71)
1.4750 - No errors 8 hours (77)

Does it seem possible that I would be able to get a Prime95 stable OC using a vCPU of 1.4250/1.4375 (bolded above) if I was to tweak some of my other BIOS settings from below?

[dnottis]

I dont have any luck with Q6600s and anything over 0602 bios with this board. Tried the 1102, does the same thing 1013 does - anything over 3.6 will BSOD while running Prime95. I can get my current chip up over 3.8 prime stable with 0602. My last B3 was stable up to 3735 with 0602, wouldnt go a notch over 3.6 with 1013.

Anyone else have problems with the newer bioses limiting quad OCs?

TBH when using E8400 and E3110s I had no issues with the latest bioses, just with the quads.

My settings using 0602 bios:

400 x 9 = 3600Mhz
266 Strap
vCore: 1.45 Bios
vCore: 1.40 Load
vDimm: 2.2

DDR2 Timings 5 5 5 15 == 1000mhz
Dram Command rate: 2N (2T)
Ref cycle time = 30 (dependent on your DDR2)
vSB: 1.2
vNB: 1.4
GTL ref CPU = Auto
GTL ref NB = Auto
Loadline Calibration... = Enabled
Spread spectrums = Disabled
CPU features = Disabled (vt, TM, C1E, EIST)
everything else = Auto

For 3.6 my settings are identical except vcore for me is 1.35v and vdimm is 2.1. Any reason why you still use 0602 too?

i'm still using 0602 b/c the newer bios (after 0906) won't recognize my usb -keyboard w/ hub @ bootup. didn't like the vdrop w/ 0906 either.

[dnottis]

Really happy with this run and my P5K-E, again this is only possible with 0602 though.

[adpr_02]

Any links for where I could find the 0602 bios? it is not on the Asus website...

Edit: Nvm. a little google fixed my problem. Here it is if you want it http://dlsvr02.asus.com/pub/ASUS/mb/...P5K-E/0602.zip

Edit: It tells me that the EEPROM type is incompatible.... wth does that mean?

[dnottis]

You have to use this version of Asus Update and go into options, check the downgrade bios option. This will allow you to go back.

Hi..

I'm fairly new to the world of Overclocking and would be grateful for a little advice please.

I would like to get my E6600 2.4GHz Conroe up to 3.6GHz on an air cooling system. However, I keep getting BSODs when testing with Orthos. I don't think it's a temperature issue as when the BSODs occur, it's usually at a temperature which hasn't caused a stop error on a 3.4GHz overclock. So before I go a little mental changing voltages, some pointers would be cool.

System Info:
P5K-E WiFi
BIOS 1102
2GB Corsair DDR2 XMS2-6400C4 (4-4-4-12) (currently in black slots)
Sapphire ATI Radeon x1950 Pro 512MB
Zalman CNPS9500 Processor Fan
4 LED Case Fans
550W PSU

Idle Temp @ 3.6Ghz - 27c (Core1 32C, Core2 34C)
Load Temp at time of BSOD - 58C (Temps taken from SpeedFan and CoreTemp)

BIOS Settings:
FSB Freq = 400
PCIE Freq = 100
DRAM Freq = DDR2-801MHz
DRAM Command Rate = Auto
DRAM Timing = 4-4-4-12

Transaction Booster = Disabled
Relax Level = 0
CPU Voltage = 1.4875V
CPU PLL Voltage = 1.60V
FSB Termination Voltage = 1.30V
DRAM Voltage = 2.10V
NB Voltage = 1.40V
SB Voltage = 1.05V
Clock Over-Charging Voltage = AUTO
Load-Line Calibration = Enabled
CPU GTL Voltage Reference = AUTO
NB GTL Voltage Reference = AUTO
CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled
CPU Clock Skew = AUTO
NB Clock Skew = AUTO

CPU Configuration:
CPU Ratio = AUTO
C1E, Max CPUID, Vanderpool, CPU TM, Execute Disable Bit, Intel Speed Step = Disabled

Does anything there look like it needs tweaking?

Is it likely that 3.6Ghz is too much to expect from an air cooled system?

Also, when I initially setup the system, one of the first things I did was to update the BIOS to 1102. I haven't found any reference to that version being particularly buggy but have found plenty of threads/posts where people have been far happier with earlier versions (0603, 1012 & 1013). Would it be wise to try flashing the BIOS with one of those versions? Would that help me hit 3.6GHz in a stable fashion?

Thanks for any advice possible..as I said earlier i'm a bit of a noob so be gentle with me

Cheers.

I get BSODs with any BIOS later than 0602 and my Q6600s when overclocking 3.6+. I'd suggest trying BIOS 0602 really.

Thanks dnottis...I may give that a shot.

Although, when I tried to downgrade BIOS to 0603 previously, I wasn't able to do it. In the Asus Update tool I made sure the downgrade option was checked but it advised that it could only be done via DOS. But when trying through the DOS tool via USB stick I got the following error: ROM file boot block is not valid. When trying other 06x and 09x versions through DOS, I was told that the BIOS version was too old and to download the latest version from Asus. I got similar errors when trying through the EZupdate feature too. I tried again with the Asus update tool but this time with 1013 and that could be done but I didn't go ahead with it. If I want to get down to 0602 or 0603 will have to flash to 10x then 09x then 06x?

EDIT: Well I managed to get 0602 on by using a different version of afudos so I just need to do a little testing.

Thanks again

What's your vCore @Load? your 1.48 is probably dropping to 1.38 @idle and even less @Load.

Probably needs a little more juice b/c of vdrop seen in later bios versions!

vdrop w/ 0602 bios isn't bad at all in comparison to 0906 an up!

[dnottis]

Pencil vdroop mod FTW!

[DoubleCored]

I've been looking into the pencil mod but i'm a little apprehensive about screwing things up. I've seen two guides which were both supposedly for the P5K-E board but the location to mod was different.

Is anyone able to confirm 100% (with screenshot if possible please) the exact place I need to 'fix' please?

On a side note, I'm not fairing any better with 0602 but I will persevere for now as the pencil mod may help things along.

[DoubleCored]

Hey guys, mind my newbie question as I have searched and google'd with no real solution to my problem.

I have the p5k-e/wifi
e8400
4gb
8800gt
vista x64 w/ sp1

The problem I have is the wifi connection.
I seem to get a dropped connection everytime I continuously download for more than a couple of hours.
This usually happens a lot more while torrent'ing.
When I try to reconnect back to my wireless router, the network availability screen shows NO networks available.
The solution? -- I had to restart my computer for the wifi to finally show the 4-5 available networks in the area, including my home network. I'm positive it's not my wrt54gl router as the solution was to restart the computer.

I have the latest wifi drivers from windows update / asus website drivers match. Also, the asus ap solo application that came with the cd is not installed as it caused more confusion.

Is the wifi not able to withstand long periods of downloads?
Is the usb wifi adapter flaky?
Or am I better off with a PCI network card?

I've only had this computer for less than a month, so maybe a bad adapter with the board?

Thanks guys.

I use the wifi on this board and I do have some problems with it disconnecting and reconnecting randomly. My laptop wifi has no problem. It could be due to a lot of interference in this apartment, as there are 8 WiFi signals here. I am probably going to switch back to the ethernet connection soon as soon as I go out and buy a longer cable.

Crappy wifi?
I have the same problem, constant connection drops. The only way to get connection back is to deactivate and reavtivate the wireless card. Happens every 5 or 6 hours.
BTW: p5k-e, q6600, 4gb, vista x64 no sp1

I had the exact same problem and was very close to RMA'ing my board. However, I managed to sort the problem out by removing the AzureWave AW-GA800BT (Realtek RTL8187) card from my old P5W DH Deluxe and fitting it to the P5K-E. I haven't had one drop out since. Although both boards use the RTL8187 wireless module, there must be subtle differences between them as I've found loads of forums where lots of P5K-E users are having the same problems. It doesn't seem to matter which drivers you use either as I tried a wide variety but none helped.

As a quick workaround, you could try making a batch file which you can use to disable/re-enable the wireless adaptor without the need to go into the Device Management console. Not sure if that will help anyone considering just how flaky it can be....at its worse, it happened every few minutes for me. I would consider myself lucky if I got 1 hour uninterrupted browsing.

I did the pencil mod but still having some problems....Orthos BSODs within a minute of starting the CPU stress. Prime95 lasts quite a bit longer but it's still far from ideal. I think I may just be at the limits of my cpu on air cooling.

Gonna keeps testing with the 0602 BIOS though.

Give it a bit more voltage and see if you get anymore out of it.

If Orthos is failing that fast and prime isnt... make sure you are running small FFTs to tax the CPU, blend will tax ram too. If you are running blend it might be your memory and not the CPU - just be sure for now you are running small FFTs to test the CPU, then you can run memtest loop test 5 for awhile to see if the ram is stable at said settings.

I've moved up to BIOS 0603 now as I wasn't very successful with 0602.

When using Orthos, I was only running the small FFTs test. I'm not sure if it makes any difference but i'm using Vista Ultimate x32..i've read a few threads where people have experienced near instant crashes with Orthos but Prime95 is much more stable for them so i'm not sure if that is happening to me.

Also, i'm have some inconsistencies regarding temps. CoreTemp, Asus Probe 2 and SpeedFan record pretty low temps of around 26/27C for the CPU and about 31-33C for the cores but Intels Thermal Analysis Tool records the cores as anything between 35C and 45C. Which one should I regard as more accurate?

Finally, I decided to start from scratch with the clock settings and have been using Clunk's P5K addon as a marker. I'm currently at a FSB of 380MHz and the only other settings I have changed is pcie to 100, enabled dampner, set ram timings to 4-4-4-12 and dram voltage to 2.1v which are the details printed on the modules. I've also disabled spread spectrum and the settings in CPU configuration. I'm gonna test things then try take it up in incriments of 5 on the FSB then start to raise the vcore, pll, nb, sb voltages if need be.

Thanks for the continued help.

Now that you mention it, I had to run orthos as admin (right click shortcut, run as admin) to get it to work - but that was with my dual core CPUs. With a Quad you want to use Prime 25.6 is the latest one. Make sure you ram is running at 800 at those timings. The ram is spec'd for DDR2800 @ 4-4-4-12 so with your overclock you memory might be well OC'd and 4-4-4-12 might not work. So make sure which ever divider your memory is at (and ram speed) is not too far OC'd.


With a quad dont use Orthos or Intel TAT - use Realtemp for temperatures and Prime 25.6.

[spinejam]

are p5k deluxe and p5k-e motherboard bios crossflashable since the 0603 bios works on both?

[Cwelle]

Why would you use p5k deluxe bios?

[spinejam]

Why would you use p5k deluxe bios?

just curious, i personally don't, but some people do use the 0603 bios on their p5k-e mb's right?

Just a little update.

I've saved two OC profiles which i'm happy with:
380x9 (3.42GHz) - 1:1 DDR2-760MHz (1.4375v Vcore)
400x8 (3.21GHz) - 1:1 DDR2-800MHz (1.3875v Vcore)

Both are stable with Prime95 for at least 6 hours (haven't tested for longer as yet but no errors at all) but they both BSOD with Orthos within an hour. Should I be concerned about that? When I run Prime95, I choose the small FFTs option and both cores are definitely being stressed. Would it be wise to use a blend or large FFTs test with Prime95 to confirm stability?

I'm also going to lap my cpu next week which should shave of a few degrees off idle and load temps. I'm not particularly worried about my temps at the mo (29C idle, 60C load) but I think they are an issue when i'm trying for a 400x9 OC so it may help. Plus i'm going to replace my Zalman CNPS9500 with an Thermalright Ultra 120 Extreme + Zalman 120mm fan asap.

Thanks for all the advice so far

Blend would also check that your ram is stable. So either blend it with prime or memtest loop test 5. Dont worry about orthos with a quad, it only runs on 2 cores anyways.
