I think pretty much everyone has this problem. It's definately not the memory. I've settled for running my system with the highest settings my PC will cold boot at. Still not slow by any means, and if we're lucky, a bios update may someday straighten it all out.

What PSU do you use Holst? I've tried two different 350's with next to nothing connected except for the critical components required to post. An Enermax and Antec 350 watt. I find it hard to believe this board requires a 400 to achieve cold boot at high fsb's, considering all I have to do is lower my CPU clock by 50mhz or so by dropping the multiplier down a notch (not even touching the CPU voltage).

It may be that your overclock isnt fully stable then.... if dropping 50mhz fixed the problem. I use a sparkle 400watt PSU, but its not so much the wattage that is the issue its the quality of the supply.

I use a Enermax 431watt P.S........ I will try to adjust the 5v line voltage up a little....... It reads 5.08v @ default settings..... When at 12*200 and 1.87v Vcore I show 4.99v..... I will adjust this up a little and see.....This is the only thing I can think of besides the memory also.... Do you all have this type of drop when you go from default to say 200 *12 or equal overclock?? Holst does your power supply have pot adjustments?? Genius what is your 5v line voltage reading at default settings in the bios? and then what does it read at overclocked settings?

I have an Antec 550w truepower, and no issues coldbooting at all, so far. My RAM will only do 215Mhz 2-2-2-5 @ 2.9v (actually 2.84v on my board ![]() Now, Exodus on the other hand, has a TopPower 370w (?) PSU, and is suffering from this problem. C1 error and sometimes others while attempting a coldboot. I also noticed his 12v was quite high, 12.3-12.6 I think, and his 5v was slightly low. This was at idle in the BIOS, so I suspect it would hurt the voltages a little more under full load. This leads me to believe it's a PSU issue. I will see if Exo will try an Antec 550w in his system, see if it fixes the problems.

yup me and ap0 are buddies so he knwos my setup well his board `n **** is here right now.... anyway ya i have this prob. but it seemed that if we turn off the power on the PSU and then turn it back on, no post, but then hold the power button and it turns the system off. then turn power back on, it works. so i dunno

well I tweaked my 5v line up to 5.06 while at 12*200 and then turned off the pc and waited 10minutes and it fired right up...... If I put it at default settings it reads 5.10v in the bios... I then turned it back off and then turned the powersupply off and waited 10min. and switched on the p.s. and then turned the pc on and it booted perfect... I then tried this through out this morning multiable times, and it booted perfect everytime..... I believe this was my problem.......I plan on upgrading to a bigger and better power supply in the next couple of weeks....... What is a good 500+ watt powersupply that holds good voltage???

I would strongly recomend against tweaking your PSU pots up. You stand a good chance of killing your mobo and PSU. There is no substitute for a good quality PSU... I could tweak up my sparkle but as it gives a perfect 5.02v all the time (measured with a multimeter) there is no need...

I have the same problem... on cold boot.. bios checksum error. Have to increase my fsb slowly.. to get back to my oc. This sucks.. does a bios update change anything? Are these errors only on the 1.1 or on the 1.0 also?

my 5v line is at 4.87v oc and at 100% load Default i think 4.98v or something like that. how low can the 5v be before it is dangerous? It is a chieftech 340w psu... will perhaps change mine soon. edit 09:21.. will look this up with a multimeter... can i tweak it up a little by changing the pots..? Quote:
