amd boot problems

[sprayer]

cant get my amd k62-500 to boot at 616mhz it runs stable at 550mhz and wont boot at 504mhz either i dont think heat is the problem it runs about 95 degrees can anyone help me with getting the 112mhz fsb?runs great at 100 mhz (by the way this is my first overclock so dont laugh at ok)thanks

Nobody's laughing, that's a good first o/c. 550-600 is the limit of the k6-2s, with some exceptions. Most can hit 550. What heatsink/fan do you have and are you using thermal paste? http://www.sysopt.com/forum/smile.gif

What voltage are you using?
Can you get it to boot in 6x100?
What are the symptoms? does it POST?
Do you get a blue screen after the windows logo?
If it cannot get to 4.5x112 maybe your other hardware cannot take the 112FSB!
Try 6x100 and increase the voltage 0.1V a time unitll it works stable (no more than 2.7V and even then with good cooling).

Let us know.

What motherboard?

550 a 600 is probably indeed the limit for k6-2's.

I had my 450@575 for 5 months, rocksolid.
But I had to be stupid and try the 600 at 2.9V.
It wasn't stabile, so I went for 3.0.
That's when I fried my chippie, bummer.

I asume ya'll understand this was a 2.2V chip, not the 2.4
Just in case ya didn't know.

Everytime you fail to boot or crash you are fraggin your hard drive. So check it before your next attempt. You may even want to run a registry check. Also clean out all unnecessary auto loading programs from your tray, for an easier boot.
BTW, what core voltages are you pushing?

ok i guess i should of gave more info sorry about that my cpu is running 2.44 volts i have two case fans @60cfm each in and one @108cfm out the top plus boxed (stock)heatsink and fan on cpu im useing a jetway j-530bf motherboard 64 meg generic pc 100 rami will try 6 by 100 today and see if it will work it will post but wont boot windows at all 112 fsb combos thanks i will keep you all informed

[otheos]

With generic pc100 RAM (10ns) you cannot go higher than 100Mhz, so no wonder why 112 does not work.
Up your voltage to NO MORE than 2.7 and go for 6x100

hey otheos you may be right i was coming to that even before i read your post. there are manythings that might be affecting your booting. you think you can post what brand of ram you have cuz i have generic sdram [cas3] too(64mb) but i can get it to run at cas2 and at 105mhz bus eaisily. you might try lowering your at bus clock multiplier steeing you may be running your busses too fast i get into that too. i also think that you might should try running your sdram at bypass i do that and i get great possibillities. i'm able to go to 140mhz bus w/ my little old k6-2-350. and it'll work fine.if you don't have these settings try disab;eing agp sidebanding and lowering the agp aperature size.(this will lower you abilliteis of the vid card but you get the processor speed out of it. i found that agp sidebanding don't GREATLY enchance vid preformance bit it do help a bit. hey why not go over 2.7volts is there something wrong w. that? i've been running my processorat 3.1 volts for a while not and i don't get any problems. one ther thing you might wanna try is to slap in a dummy drive just for booting that don't have your files on it you want and boot off that until you get it going there is always a way to get the processor to go faster now weather it's safe or not depends. i found that this meathod has saved my @$$ many times. also otheos you don't get a blue screen in windows unless your running win nt or 2k. win 98 just says win protection error and you must restart your computer or it just locks up.

ok i cant find the jumper settings to go to a 6 multiplier my manual only shows 5.5 so i guess im outa luck till i get some new ram i didnt get the brand name off of the ram yet but i will i had buttoned up before i got the new post and im tired of playing for today but tomarow is another day and i will try again anyone know of a place i can get alpha heatsinks in socal if you do let me know thanks for all the help btw yes on paste

hey if you have a k6-2 from what ive hear they remap 2x as boing 6x so try it i haven't yet cuz my lil old k6-2-350 again. http://www.sysopt.com/forum/frown.gif

[sprayer]

do you mean if i set it up for 2x it will run at 6x i dont understand?

[CMonster]

Nothing to understand - take it on faith - if you clock the newer AMC K6-2/3s by a multiplier of 2x the CPU interprets it as 6x.

sprayer if your close to san diego you can get them at the Chip merchant they carry a full line of heatsinks and fans http://www.sysopt.com/forum/smile.gif
you can check them out at www.thechipmerchant.com (http://www.thechipmerchant.com)
and If your going to try for 600MHz be ready to buy a new chip I've gone through 2 of them lol http://www.sysopt.com/forum/smile.gif and still going lol http://www.sysopt.com/forum/wink.gif

ok here is the latest got it to boot and run at 6x95 @2.8v but she ran a little hot so i backed it off to 550 again so it can wait till i get a new hs/fan this weekend tried 600 but had problems failed post almost though it will need a peltier for 600 im sure thanks to everone for all the help ill let you know if i make it to 600 keep your fingers crossed thanks
