What on earth can cause this?

[oqvist]

I got a 1600+ that are good for 1807 hertz approx.
A 8rda+ rev 1.1 board
Got a crystal orb on the northbridge and a zalman NB32J on the southbridge and some heatsinks on the mosfets.
Also got a Antec 550 W Truepower PSU and 2x256 mb Corsair XMS 3200 CAS 2.

It used to run fine at 180x10 or even 190x9.5 but now for some reason when booting windows it just restarts. Trying safe mode same result. Running default settings 100x10.5 the same. Doesn´t matter what I do I can´t boot windows anymore?

wth can cause this? I have never had so much trouble with a mainboard since I got this one.

Look at your temp readings...........

1807 herz is a bit on the slow side....

Another one with an Orb on the NB - I've asked this question now on several threads but haven't yet really got a reply - does the Orb fit the NB ok with the push pins, or did you have to Epoxy it on? Sorry this doesn't help your problem much, but I'd appreciate the info.

if it will boot and you can get into bios, check pc health and see whether all fans running. had this happen to me when i forgot to turn on water pump and cpu overheat protection kicks in before you can get into windows. also check shut down temps in pwr mgmt in bios. if room has warmed up, you might have it set too low. don't mean to insult, its just that i have done this and if somebody else had not pointed out, well... also consider any recent driver changes, although you'd think safe mode would cover that. run in scroll lock, if you can, and see where it hangs.

Jeb, no crystal orb does not fit with pushpins according to numerous threads. mine is on order and should be here tues. currently contemplating as3 and epoxy around the edges, unless the thermal pad looks good. also have some extra akasa/shinetsu pads, although they are too small so would have to use multiple and cut to fit. guess i'll decide once i have stock hs off.

[oqvist]

Temps are loooooow. No heat protection activated. All fans running. Doesn´t have any clue what causes this. It´s not video card related (or shouldn´t be since the same occurs with two different 9700 PROs). My cpu doesn´t like higher speeds than 1807. To bad I had to exchange the 1600+ I got earlier it dit 1853 without a hitch.

And the 1600+ should be able to run at 2.1 V without being damaged? Am normally running on 1.9 V but tried to see if upping the voltage more would increase the overclock which it didn´t.

The voltages for my corsair is either 2.63 or 2.77 V. Have tried both settings didn´t make any difference.

I have heard the BIOS chip on this mainboard is crap. Can a faulty BIOS chip cause this kind of problem?

[fast--]

my 1600 would only do 1853 at 2.025v, it just depends on luck. if you can get into bios, i don't think bios is the problem, but if you have the boot floppy with the bios on it, you can try reinstalling, or get the updated bios some other way, transfer to your boot floppy and update. that should tell you whether bios is the problem. i think most of the problems with bios relate to aggresive mem timings. post your timings. i've been able to access bios but not get into windows with too aggresive timings.

[oqvist]

Well I am running 6, 3 ,3 cas 2 I thnk so that isn´t that aggressive for my corsair xms 3200. I reformat and reinstalled everything and it seemed to do the trick. Don´t understand why especially since I got the same problem with two different win xp pro installs. That seem to exclude that there was just a harddrive write error or something that caused it.

Weird but I am happy.

[oqvist]

I have no internet connection and of course M$ wants to punish me for it.

oops wrong thread but anyone

[Terryb47]

i think that Corsair recommends 2.77 for your vdimm. so why not, higher FSB requires more voltage for the memory too. some peeps have it at 2.9 even.

[ReallyUgly]

rebooting are signs of too much OC . I had it when my ram was OC too much..

Check ram with docmemory.. search google for docmemory

at least you can rule out memory (then)

goodluck

reinstalling windows ?

[timbob2469]

oqvist , Youcould test your memory with memtest86 . You download it and copy it to a floppy ,reboot with floppy as first boot device . Let it run for at least 2 hours , overnight is better.

Well the rebooting occured even when running the memory at 100 Mhz. I got it fixed by reformatting and reinstalling win xp and everything runs fine now. Have absolutely no clue what caused this. You could guess it was some harddrive failure but since it happened on 2 different installations of win xp and two harddrives it was definiately something else weird going on.

Well the RAM do 180 without a hitch, I think even 190 hertz and maybe higher (I am guessing it is my cpu which doesn´t like that high of a fsb) but I haven´t had time to thoroughly test what my bottleneck is.

[mpa4712]

the cpu shouldnt really matter with the fsb, long as u balance it with a good multi. Its funny that u say a new install of xp did the trick. I believe there is an option in the bios called apci that u should disable b4 installing windows. It makes windows install a different layer for your hardware, so, if u still have the issue, look for that setting and disable it, since its enabled by default.

I will try that if the same happens again. thanks for the advice.

[oqvist]

Hmm, I think I have found out what caused this. My computer didn´t like me disabling the power saving features in bios. (ACPI I think it´s called). Enabling it again and windows booted like it should.

I got one disturbing thing going on and that is that everytime I start windows xp it wants to scandisk my old harddrive. A little annoying even if it´s of course isn´t any big problem

As it would do! ACPI mode requires a slightly different set of options in the Windows kernel in order to work correctly. If you disable ACPI after installing Windows on an ACPI machine, odd things do tend to happen!

[oqvist]

Okay, so what do you recommend for my next windows install? Does ACPI affect overclock stability or performance or doesn´t it matter wether it´s on or off.
