Aparently AMD cpu's come with a lower stock fsb when they ship and there is an option in my bios for 200mhz over 133 I'm currently running about 38 idle and 47 full load (that ill ever reach), is this still safe? will it take life off my cpu? whats the max voltage it can go without taking life off it? Current V-Core is about 1.68 how will I rise this?
 
wow you ARE no0b

is it safe?: yes
will it take life off?: maybe, like it may take a month off of it's 5year life span
max volt w/o taking life off?: stock volts
how to rise?: in BIOS, prolly under power management or somehting similar
 
Heh, thanks, I kindve knew those answers just wanted to make sure. :)

Edit: Also how far could I go here without taking say more then 6 months off cpu.

KINGSTON DDR NON-ECC PC2700 CL2.5 KVR333X64C25/512 512MB MEMORY 333MHZ
Barton 2500+
Asus A7N8X
1 high cfm fan taking air in and a silent low cfm fan taking air out with a heatsink.
 
With air cooling I would't go higher than 1.8 or maybe 1.85 Just to be safe.

Also cpus last years and years and years. I've seen cpus that as they age don't OC as high as they used to but I wouldn't worry about it dieing on you. Just keep a close eye on your temps, that's important. Good luck and have fun.
 
And that would let me get around 2200-2400 mzh max? Although I probobly wont take it there till I get my new fans :D (4 80mm deltas)
 
2.4ghz on air is very possible but I wouldn't count on it. It all depends on the chip. I had a Barton that needed 1.85 to be Prime stable at 2.2ghz and another that could do it at 1.75. And there are some lucky bastards with chips that'll do it at stock 1.65


Also with the nForce2 chipset it likes to have the FSB and the memory in sync because of latency. If you plan on doing 400mhz FSB get 3200 ram and run them in sync.
 
im running 2.6ghz on air.

it is ALL ABOUT THE TEMPS!

you can go up to 2.1vcore on a 2500 without danger. Read the AMD specs if you don't believe me. Keeping that in mind, stability and safety is a question of temperature... nothing more.
 
Mine will do 2.2ghz at default voltage all day. However, no matter how much more juice I give it, it refuses to go to 2.3ghz.

I just got another chip in today that can't do 2.2ghz at stock...looks like it'll probably need around 1.75-1.80.
 
mine also does 2.2GHz at 1.50v, and up to 2.3 at 1.65v. the diode will read 21-25C. its rediculous. :D anything past that i need to start giving .1v for every .5 multi. heres my best so far, at 1.90v.

this is a crap PSU, and top of that, i read a lot that DFI boards tend to undervolt. my 1.90 Vcore has gone as low as 1.81 since the screenshot-- thats a 6.7% flux. i hope i can do better than this with good power and mebbe a voltmod. a new cooler would be nice too.

i got the memory from MetalX just yesterday. its workin out good so far.

Without getting pc3200 ram, you won't be able to hit 200 mhz FSB.

If your chip is new, odds are, the multiplier is locked.

Set your FSB and run it at 166 like the manufacturer suggests. When you learn more about overclocking and have the appropriate hardware, then try the 200 fsb.

... wtf?

so way back before pc3200 was even out... I wasn't "really" running 200mhz FSB eh? *sigh* What exactly do you call overclocking?

Good pc2100 memory can hit 200fsb pretty easily. I remember a 256mb stick of crucial pc2100 that I had would do it at STOCK voltage.
READ A BOOK!
 
You could always run the mem and FSB asynchronously. Like the intel boys do.
 
not really. most people say AMD systems run like crap with dividers, and i cant even boot with one.

WRONG, i got me some pc2700 kingston crap ram that was the cheapest newegg had, and look at my sig, running that 200fsb 1:1 all day long.....

Were you running your 2100 at 2-2-2 timings at 200mhz and looping memtest over night? Given the slight price difference these days there's nothing wrong with someone recommending him get 3200 that's supposed to run at those speeds anyways. Plus he might decide to go beyond 3200 speeds, something that econo Kingston will not do.

Nice OC dobbz! I'm glad you're enjoying that RAM, it's been running at 3200 with SPD timings and was living a tame life compared to other BH-5 chips out there.

yes, but new ram might be a waste for him, he isn't using PC2100, and i've seen PC2700 ram hitting 200fsb at some very good timings
 
For some reason I was under the impression he was ordering these parts. If he already has the ram, I'd just try it at 3200 and see if it'll do it. I had some Kingston 2100 back in the day that would do 2700 at very tight timings so it's possible. Our main concern was that he run at 1:1, as it's in his best performance interest.

why is it that Intels work fine with mem dividers, but AMDs don't? is it because of the "quad bus pumping" or whatever so the P4 opperates at 800FSB or what?
 
I can get mine up to 166x12=1992 (gonna try 12.5 highest it goes later today) Any way I could set my fsb up to say 170, 175 ect? The only options i get is 100, 133, 166 and 200. Also what advantages might I get outta a high vcore.
 
Well you get greater stability if you need it but it's gonna raise your temps. Keep testing and you'll find your vcore/fsb/temp hot spot.

As for the 1:1 thing, it has to do with latency, but someone more qualified could explain it better.
 
Temps are 37 idle 50 load right now. Still stable though so I guess im all good till I get my new fans.
