E8400/Asus P5KE Overclock boot problems with Asus 5850...

[Apocalypse23]

So I've bought an Asus 5850 for my E8400 setup on a Asus P5K-E wifi board. The card worked fine initially, but after I restarted the machine would not post, and would give me 3 beeps. To solve this I removed the 5850 and connected my older 4350 onto the PCI-E slot, and had the same problem. Then I inserted the 4350 into the second PCI-E slot and the computer booted, but returned with a "Press F1 to enter setup, overclock failed" message.

I had been running my older cards including the 8800 GTS 512, 9800GX2 and also the 4350 with similar overclock settings and never had any posting issues. The 5850 does not want to work with my CPU at an overclock, it works initially after I swap PCI-E slots and boot, then when I swap back to PCI-E slot and set the E8400 to even a slight overclock, the system boots and games run great, but then when I restart or perform a cold boot, I get the same posting issue.

When I don't have the system overclocked, the 5850 boots and restarts fine....

I'm looking into swapping this card with my other machine to find out if it works on that, from what I'm sensing, there is an incompatibility issue with my motherboard or Ram overclock..

Please help.

*EDIT*--Problem FIXED (had to play with motherboard overclock voltages/settings, see below)

I have similar problems with my p5e3, e8400, and 4890. I'm currently uninstalling all ati software, and doing safe mode-driver sweeper. Next will be all the newest patches & updates, and lastly I will install the 8.703 betas. I'm in winXP.

Sometimes it works, and sometimes it doesnt. I've switched between 6 or 7 driver versions, and for me, the issues is mostly the driver. I've tried stock cpu&mem, stock gpu and still had crashes midgame.

I have to say, overall this is the most trouble ridden PC I've ever built. Can't figure out why. I think I will switch to Windows 7 after this.

Good luck with your 5850, Are you in windows 7?

I'm using Vista 64, but can dual boot with Win 7 64 too.

I think my problem is mainly hardware related though.

since you say the 5850 works fine at default non-OC settings, I would suggest starting over with your CPU overclock and find out what is stable with the 5850 then compare the differences in OC settings.

edit: nm read the part about the slight overclock. have no idea what could be causing the instability issue with the 5850 and your system. is your PCI-E frequency locked at 100 MHz?

Yes I tried it with locked and auto, no luck...I also swapped my 5870 into the same machine and still the same issues with the beeps...the 5850 works fine on my other overclocked e8400 with P5Q pro board....I think my motherboard is too old to support to these cards with an overclock....

Might be a longshot here, but when I installed my 5850 on an IP35-Pro and e8400 rig, for some reason an audio controller was detected and it would NOT play well with the IP35's Jmicron IDE controller and the onboard audio. I had to disable the IDE and onboard audio, then boot and disable the "audio controller" found when the 5850 was installed. Once I did this everything was fine and I was able to re-enable the onboard audio and Jmicron controller.

I got all kinds of strange errors in the process after installing the 5850 until I disabled that strange audio controller (audio over HDMI i guess?). I saw everything from failed POST to BSOD's to horrible in-Windows performance until I fixed this issue.

May have nothing to do with your problem, but your post brought back those nightmares for me lol.

I just fixed my issue. It turned out that when I was overclocking, I had left almost all settings to Auto except my CPU voltage, Ram voltage, Ram timings and FSB. I tried overclocking with giving voltage to NB, SB, Disabled CPU Spread Spectrum and voila, everything works!

I haven't had such a stable overclock in years, I',m now running at a core voltage of 1.30 from the BIOS and have the E8400@4.0 GHZ (445x9), everything works like a charm so far, no more rebooting or cold boot isses with the 5850.

Thanks for the suggestion, I actually figured it out by playing with the BIOS, turned out my Oc settings were wrong.

Cheers.

*EDIT*
Just ran 3d mark vantage and got a performance boost, overclocked the 5850 to 835Mhz core and 1070Mhz memory:
P12433
GPU:15583
CPU:7739

Updated:
New score with newer voltage settings and 5850 on stock:
P11700
GPU:14015
CPU:7824
