system specs:
===========
AM2 X2 4200+
EPoX MF570SLI mobo
1 x 1GB Hynix DDR 667 RAM
1 x 320 GB Seagate HDD
Sparkle 7800gt @ 485/1150
450w Procase PSU
Gigabyte Aurora Chassis
Zalman 9500 AM2 with AS5
okay from messing around for a month now here's what i know:
mobo is prime stable up to 319mhz, but wont post at anything past 270 (i think its a bios issue)
ram runs rock stable @ 800mhz 5/5/5/15 1t @ 1.8v
my machine is dual prime stable at 2750 (250 x 11) @ 1.5v
(i run dual prime to check if its stable)
now thats a pathetic oc... i'm not happy with it at all... i've seen how guy online got close to 3ghz at 1.5...
the machine boots and run everything fine at 2805 @ 1.55 but isnt prime stable, i can superpi fine at that speed. I've been playing with the voltages and it hasnt helped.
i tried 2805 at 1.6v, max ht voltage, max chipset voltage with ram @ 533mhz to take it out the equation...
its not a heat issues cause at 2750 @ 1.6v with dual prime for 20mins the temp maxes out at 55c. I'm beginning to think i got a gimp 4200 x2.
any ideas on what the problem could be? i know my chipset runs really hot could that be causing instabilities? the reason i dont think its that is cause the motherboard runs fine at 300 x 5...
any ideas? i'm a bit squeamish about putting the voltage up to 1.65 or 1.7...

This is where it all goes wrong, some guy's chip is not yours, and 3ghz stable on acceptable voltage is pretty rare. Be happy with almost FX-62 speeds, you wont notice those extra 100 or 200Mhz anyway. If you want extra power for your games get decent videocard cooling, voltmod it and then watch your 3dMarks go up..

i'm trying to break 30s on superpi... it seems everyone on every forums i visit can get their 4200+ higher than mine...

Might be your :banana::banana::banana::banana:ty PSU...
Look into something from Enermax, Tagan, etc. Head over to the General Hardware section and click on the PSU sub-category, and read the Tiered Manufacturer list.

Also another thing to look at the 3.0 Ghz chips I have seen so far for AM2 have all been single core. THere may be some dual cores out there but the ones I have seen are single core. It would be much easier if the ram had a little more room to play with, like DDR did. That is one thing we are fighting with DDR2.
most people with 'mediocre' clocking chips don't post their results.
Thrust me , a lot of people have cpu's which are worse than yours.
For example , I have an X2 4400 which won't do 2.6ghz . running 2.4Ghz and that's fine for me.
If you want 3 Ghz , you better look for a 'known good stepping' or a pretested cpu.

My son's 4400+ is 2.5X max...My 4400+ does 2.8Ghz, same ram, psu + mobo...

Either you have a "meh" CPU or your PSU is holding you back. You could also try remounting CPU cooler. Temps mean nothing. Contact is everything.

well said. not every cpu is the same. even from the same week/batch code, there can be exceptionally large results. take a look at the first s939 opterons..
two 144's and a 146, all CABNE 0530AMPW.
one 144 did ~2.75-2.8ghz stable
second 144 did around 3.1ghz stable
146 did around 3ghz stable
Talking about bad overclocker my single core stable @2.6 with 1.42 v but not stable @2.75 with 1.6 v it is all about good and bad steppings

in overclocking.. you ought to have the right hardware and software and knowledge.. and the most important thing, you should be "lucky":D

man, dont worry about it. sell that chip and get yourself another and it should clock better. at least you can do over 2.6 GHz stable, unlike me. i thought maybe i could be stressing my psu too much, but im not completely sure about that. it should be strong enough. you on the other hand should get a new PSU. cheap power supplies can kill hardware without any warning.

2750 is alright. Definately not the greatest, though.
It doesn't have to be prime stable. My 175 has been going pretty much 24/7 for ~6 months processing images from my camera, playing games and running FAH without a single BSOD. It fails prime in about 10 seconds, though.
It might be a good idea to get a multimeter and check out your psu, however.

okay played around last night, its prime stable at 254x11 (2794) at 1.55v... it boots and runs games and everything fine at 2850 but i cant prime at that speed...
i guess i gotta be happy with 2794 (i'll round it up to 2.8 to sound better) :P i cant believe i cant get that 1 mhz to push me over 2.8!!! DAMN YOU OVERCLOCKING GODS! hehe
there was a magasine available here : CustomPC where they put 1.7v through a 4200 x2 on a abit fatal1ty board on AIR! even i'm not that crazy!

bah dont worry about it dude, I bought a Opteron 165 0610 DPMW off a girl who had it @ 2.8ghz default voltage under water cooling. I also bought her motherboard and her RAM.
Dissapointingly was a different story for me tho, Im sitting at only 2.75ghz @ 1.4v and I cant, unfortuneatly, cool it much better in this QPACK cuz its so small in here...Im on air cooling and my temps at that speed and voltage are like 44C idle and 60-63C load.(they drop about 5C when my room is cooler)
Obviously the temperatures are holding me back from wanting to up the voltage anymore and getting more mhz out of it. =(
I havent tried any higher, I know most people can run these @ 1.5v @ 2.9-3ghz on air...but temps are just not on my side this time =/
oh well, I know its an amazing chip and 2.75ghz is plenty fast with 2 cores....be happy with it hehe, thats a 600-800$ processor for what....200$? or less?

@Coldon: I think you are quite well. I'm watercooled and i can't do better than 2850 at 1.6

This is called the cpus/mobo limit. With that cpu, on another board it could go much higher. For example, my cpu can get upto 380 x5 but max out at 3ghz on 316 x9.5. on 1.55v I never tryed more because of bios issues in beyond 1.55v will not work with this bios but newer ones it does.
A board that can do higher volts like a dfi would be better for me. But semprons are capable of running full speed x7 to x10 and reach between 430 x7 to 320 x10. That means 3.2ghz. Strange with the same board, when in the bios it will not go over 280 for me. But with a sempron it goes to around 400 in the bios.
My point is, boards like different cpus better then others. One will get insane amounts of X multiplyer speeds others only Ghz speeds or both. Depends on the cpu and what the board likes. Its almost like they have a mind of their own. lol Thats just how it is, strange I can get to 316 x9.5 useing clockgen but not in the bios. And 380 with a x5 or x6 multiplier. But any higher its about 350 for x8 330 for x9 and 295 for x10. Solid multipliers suck on this board thats why half multipliers work better.
I get error error error with x10 but with 9.5x I get 3ghz stable. Just the heat is a little much at full load.

maybe you need to accept that your chip won't do that speed...I had to do the same when my 3000+ Venice fell short of 2.8GHz

yeh, i'm kinda set on 2750... thats equivalent to around a 5200+ x2 right? that'll do for now... now i need to get some cooling on my vid card and voltmod it to 1.5 and see how far i get with it :P
I also just realised that if i get a new sound card it would probably boost my performance about as much as overclocking my vid card :(
