No matter what settings I use or how small the overclock is, it crashes every single game - despite being stable in everything else :(

Specs are as follows:
P4 @ 3.2Ghz
P4C 800-E Deluxe
2GB "no-name" PC-3200 400Mhz RAM
ATI Sapphire Radeon HD3850 512mb
460W CM PSU

Any ideas?
 
It might be the ram, if you up the FSB, your ram automatically gets overclocked too, have you tried dropping the ram speed a notch ( while keeping the same timings?)

I had the same board and northwoods easily did 3.8 ghz (any more and you might kill the cpu in a few months running it like that, I was never so unlucky but iirc I can recall the northwood sudden death syndrome) , prescotts did 4 ghz or more, provided they had good cooling, mine rose up to 78 C under load at 3.9 :(. They ( prescotts) went really high, but needed a big block of metal cooling them down.

Hello Cookeh,

Strangely enough I'm overclocking a similar set-up for a friend right now! :)

I think the problem you are having is as snowdog says . . . this "2GB no-name PC-3200 400Mhz RAM" may be not that high quality and therefore can't take any extra strain past 200MHz? . . . What does it say in CPU-z under the [Memory] tab?

There is an option in BIOS to drop the memory multiplier down, I think it starts at 400MHz then the next one down is 320MHz, select that and you will be clear to run the FSB all the way up to 250MHz without the ram running beyond it's 200MHz spec!

Here's some CPU-z tabs from the 2004 system I'm trying to tweak, having some problems getting the FSB up to 250MHz . . .think it's the five year old Ballistix Ram on its way out, did try that memory divider option but this particular ram doesn't work properly with this ASUS P4C800-E at anything other than [1:1] sync!

Hi Cookeh, you missed the [Memory] tab in your screenie! :D

I'm guessing it's gonna say [1:1] 200MHz and if so that seems to be the problem for you because as soon as you raise the FSB your immediately overclocking the memory!
 
Well there's not much you can do if dropping the memory multiplier doesn't work, apart from digging up a stick of PC4000 from someone's Ghoul-Box the only other thing you could try is relaxing the memory timings to 4-4-4-12 and switching vDimm off stun and set it to kill! :D


  • 207MHz Ram = 3.3GHz CPU
  • 213MHz Ram = 3.4GHz CPU
  • 219MHz Ram = 3.5GHz CPU
  • 225MHz Ram = 3.6GHz CPU
 
Is CAS 4 even at option on those older boards? 3-4-4-8 might be more like it and it looks like its set to that via the SPD. If the memory is no name, and if my memory serves me right, boards from that era were touchy about big capacity modules then you'd need some good stuff to overclock. I remember having to relax the timings on some corsair 2 3 2 5 2gb (2x1gb) dual channel memory to 2.5 3 3 6 on that very board. Honestly though, doubt you'd get much improvement on anything on that system and even an entry level cheapo core 2 based system will eat it alive.
