HELP!!!OverClocking

[joek71]

Hello

I have a question. I have Abit Motherboard KG7-Raid with AMD ThunderBird 1.3ghz cpu, video is NViDia GeForce3 Ti 200, DDRam 512-2 sticks=1gig Ram, Running Windows XP. Now the problem is that when I over clock to 1584 and shut down the computer for the night and then turn it on in the morning I get this message WINDOWS\System32\Config\System is missing or corrupt. The way I fix it is I bring down the clock speed under 1.33Ghz. Can some one please help me out here? Once I bring it down it loads fine. Why does it keep doing that?
Please advise!!!

Thanks in advance,
Joe

dont shut the computer down :)

could be many problems, i would look at your hard drive for one it may have issues not wanting to run oc'd, is your core voltage resetting on first power up? i know mine does unfortunatly i have to boot at a slower speed with the voltage upped then restart at the higher voltage and increase fsb

I have 2 Maxtors 30 gig each with 7200 rpm. Are these good drives?

Thanks,
Joe

the maxtor drive that i dealt with would fail about 150 fsb,
alltho that is 38pci (about) you arent very close to that it could very well be that... i would suggest trying an install on another hard drive to see if it will finish posting. older hard drives are typically less sensetive to fsb from what ive seen.

cant really say its a "bad" drive. but iknow its not the best esp. for overclocking.

my seagate would operate fine at the fastest mode up to an fsb of 178 (44.5 pci) and turning down the settings... udma etc. would allow it to run up to 49mhz pci (98 mhz fsb)

if you cant try another hard drive... i would try other fsb / multiplier combinations... run the processor lower than the rated speed...at say 1.2 ghz... with different fsb combinations to ensure that its not your proccy holding you up

If the PCI bus causes those problems you can try to increase only processor FSB, I think it is possible in all ABIT's motherboard...

[tripodal]

thos abit offers an adjustment for increasing the processor fsb... it is quite misleading as the pic/agp/memory busses are always upped with it. there is not a way to up just the processor fsb, as all other buss speeds are divisors.. or mulitpliers directly of that number

I have a similar prob. My kg7-raid with XP1500 running win 98SE, soon as the clock speed hits 1500 windows registry rescue kicks in and restores and old registry so nothing works! Bloody annoying and i dont know why?! I also had agrovation with over 512MB of ram, windows needs to be configured to accept it, otherwise screwy thing happen!

registry corruption on startup is more likely to be caused by memory than hard disk.....what voltage is the memory set to whilst overclocking.....and does it have any cooling attachd (ie heatsink)

[joek71]

My memory is Mushkin DDRam 2 sticks of 512 DDRam, I spoke to mushkin and they told there should be no problems, I also ran a test to check if my ram is good, and it passed the test so it is not my ram.

Thanks,

im at a loss then as to why it wouldnt restart the morning after, i guess we will need more specifics.. such as temps/voltages on restart, perhaps you can try tests with different parts missing ... extra cards.. (sound network diff grafx card etc.)
on the restard the morning after... does it even post? or does the post crash till you get into windows.
or does it post at the oc'd speed and punk out while loading windows
?

Don't know what type of test you ran, but many tests arnt as hard on the memory and cpu as when you boot windows!!You should try a small test proggy called "prime 95"....leave it running on TORTURE SETS for an hour or so, and you will see what kind of probs you really have.Noone can tell you over the phone that your memory is fine, specially if your overclocking it without increasing voltage or taking care of cooling!!!
