***OFFICIAL Asus P5K-E/WiFi Thread

The marks on cpu is normal...it seems you have one of the not so good quads.

[Mordorr]

I confirm that too...

If you go post 141, you will see a litle mark, on the mine, too...

Maybe your CPU isn`t so good....

I do have also some dificulties in reaching 4G....and i even did try Prime95

I would understand if the cpu wouldnt clock, but I can run Prime without erros for about 1 minute, sometimes 2 minutes and then ... REBOOT again. Also, how can it become unstable by throwing 1,45V into it?

here is the cpu (I marked the scratches the cpu came with):

Hey,

I got the P5K-E/WiFi last week and installed it. Cooling mosfets with thermalright Hr-09 type 2 (pics to follow)(hardmounted). Cooling NB/SB with thermaltake extreme spirit II heatsinks. Cooling E6600 with water. 850watt antec TPQ PSU, 2gb Pc2-6400 corsair xms2 (5-5-5-15-2T, 2.10volts)

I installed bios 0901 before finding out about the vdroop. I can not return to 0602, 0603, or anything else. I have tried EZ flash in the bios, and Asus update utility in windows Vista 32bit. Update utility says "Bios image can't use in this motherboard. The EEPROM type incompatible." EZ Falsh says the bios is older than the 0901 bios, which is obviously correct.

Can some one suggest another method of downgrading bios to 0602?

I can not understand this method.

Did vdroop mod from page 1 of this thread, brought up the droop a little. Still a large gap, almost 0.1 volts

[Rovtar]

in asus update go to options and then check the box before bios downgradable

[Aerou]

for me the downgrade option didnt work for 0901, so I did this:

• prepare desired bios and rename to P5KE.ROM and put it on a FDD/CD/DVD/pendrive
• start updating the 0901 with 0901 using EZ flash
• during the process restart/shutoff
• during next restart, the Crashfree feature starts looking for a medium with the P5KE.ROM file - insert the media
• let flash complete - and there U have it - never use 0901 again

... remember, its always at your own risk!

Other BIOSes (for example 0806 into 0602) can be easily downgraded through Asus UPDATE setting the 'Downgradeable" option in settings

... GOOD LUCK

[spider_d]

Thanks, except bios can not be downgraded through Asus update program on my motherbaord. I have checked the 'downgradable' option in the program and started receiving the message, "Bios image can't use in this motherboard. The EEPROM type incompatible." This is not the same message that I recieved before checking the 'downgradable' option.

I will try your method Aerosupra. Hopefully I can confirm success with this method in the next few minutes.

[Aerou]

in case of a flashdisk (pendrive), use HP USB Disk Storage Format Tool, so that EZ Flash has no problems, just for safety

When you tried downgrading did you use older updater like AsusUpdt61002 as seen a few saying it works.

[mft4]

i used the AsusUpdt61002 like others and it worked a treat, thanks a lot guys.

[spider_d]

Aerosupra's method worked. Downgraded to 0602 without trouble. I was using AsusUpdt_v71304 from the Asus site.

Thanks for your help. I will post a few pictures tomorrow of the cooling solution. I will also play with the Bios and try to reach 4.0 tonight.

Any suggestions on NB/SB and other voltages?

[Rovtar]

why to 0602?

use 0603.. its way better bios than 0602.. i can now easily achieve 3,6GHz on my e6750 for 24/7

[Aerou]

agree, 0603 works better, now, since you haven't got a 0901, you can change your bios without the Crash-method

here are some P5K-E wifi BIOSes:

[mft4]

when you say 603 is better, are you referring to being more stable, or other reason?.

[Aerou]

I can push FSB a little further, but Vcore is more stable (unless you have already pencil modded your board)

[AriciU]

I've tried to update from 0602 to 0603 using the EZ Flash thingy in the bios but it said "boot block not valid in file" or something like that when checking the 0603 ROM.

[vocch]

Make sure usb is formatted before you put a rom on.

[AriciU]

Formated and retried. Same error msg :/

[Rovtar]

update using asus update in windows..

no problems

[spider_d]

Thanks fellas, I see that 0602 is much easier to overclock then 0901 and am going to give 0603 a try now. I can easily hit 4.0 on my e6600, with nothing but Vcore voltage changes. However, the temps are to high for 24/7 so I will be runnning 3.6.

I have encountered a few issues. I can not set memory timing to 1T. I does not matter what I do with other settings. This was not a problem with my 680i board.

Everest benchmark shows a large drop in memory read (20&#37 and increase in memory latency times (70.8ns vs. 57ns). And the worst part is that I am overclocking the memory and cpu more than I was when I got higher scores! Memory write scores show 10% increase and memory copy scores are nearly identical.

Last issue, my video card is running slow. 3dmark06 is running at 30FPS instead of 90FPS in the first test. I am about to re-install the drivers and see what happens. Is there a setting in bios that I have disabled that affects GPU performance?

[spider_d]

Update: flashed bios to 0603 and now have GPU at normal level of performance. It might be a driver conflict with older BIOS or a hardware issue because the new 8800GT support PCIE2.0. I do not know, but am glad that it is working now.

Time to overclock

[spider_d]

Well, here is the problem. My GPU starts running slow when I overclock past 3200MHz. At 3600 my 8800GT is running at 30FPS. At 3200 my GPU is running at 80FPS.

The only changes that I have made between the two CPU clocks are FSB and Vcore, so somehow one of these settings is slowing GPU performance.

Anyone seen this before? Any solutions?

[AriciU]

Check your pcix speed if it's set at 16x. Also try setting the pcix clock at 100mhz in the bios.

[Mordorr]

Hi.

Nice to see people excange new experiences...

Im on vacations, so no acess to my rig....

Im thinking to try 0603.....but before new update, should i do a default reading in the Bios?

And them update?

cheers,

[spider_d]

AriciU, where is the pcix setting to 16x? I set PCIE clock to 100. I still get slow FPS at higher clocks than 3200.

Anyone know about the PCI/PEG setting and Asus cross graphic impeller?
