Have you ever thought of bumping up the front side bus one night only to find yourself reinstalling your operating system the next day. Some people are dissapointed when they can't even get 100 MHz out of their processors even though they are being cooled by a waterblock. They automatically think they were foolish or stupid. They believe that thier processors were hacked at a limestone quarry instead of being carved out of living ivory by the hand of God. This line of thinking would have made sense back in the old days of 0.25 micron fabrication and maybe even 0.18 micron. as well. however as 0.13 micron being the standard today, it no longer comes down to the luck of the draw or the quality of the fabrication. You can find out a great deal about your processor and estimate how far you will successfully O/C it before you even buy it. Please explain?- Throughout the term of a processor life cycle the processor will go through several steppings or versions. Stepping simply reffers to revisions in die or core design by processor manufacturers. Every stepping indicates a change in the cpu manufacturing process, which ussually has an impact on physical charactheristics, such as maximum temperature and wattage of the cpu, pipeline depth, core voltage, transistor arrangement, sillicon layers and a myriad of other things. intel pulled off 2 GHz on 0.18 micron fabrication with the d0 stepping . this started at 1500 MHz, But never broke through 2. GHz. To go faster Intel moved to 0.13 micron and a new stepping- several in fact, before topping out at 2.6 GHz. The message here is that some cpu's have little or no overhead left at some point of the manufacturing process.

I am the owner of an XP1700+ JIUHB Stepping cpu. It might not sound impressive but if you check out http://www.hexus.net/content/reviews/review.php?dXJsX3Jldmlld19JRD01MzY= you will find out this is an extremely overclockable stepping. My current motherboard is an ecs k7s5a which is a pathetic overclocker. So I am planning on getting an ABIT NF7-s for the sole intent of overclocking my processor. And i am thinking about replacing my 256 MB of pc 2100 with dual channel pc 3200. And replacing my heatsink with a specialist cooler.

The JIUHB stepping has been overclocked to 2.6 GHz but some have not even reached 2 GHz. But according to many hardware forum's, most of the JIUHB's will do 2 GHz @ stock volts.

it's interesting..
I bought three of them, not guaranteed ones or anything, just three off the shelf ones.
All three do 2.2ghz stock voltage, i'm not currently watercooling them, so I don't push them above that, but i've tested them easily @ 12x220 @ 1.65 volts. 220 is the max fsb that they will do on my nf7-s.

I am not quite sure what the point of this thread is.....

Back in the .25/.18 days (not long ago might I add) there were in fact a number of different steppings that could be guestimated in overclockability.

Pentium 333's had a few steppings, one of which was easily capable of 560MHz for many people, where as other steppings couldn't even come near.

Celeron 300A's were the same way, certain steppings provided consistent results.

Moving on to .25 Athlons and Tbirds wasn't so much an issue of stepping as "did they stick a 650 core in my 500 or a 500 in it?" This I guess agrees with your argument of luck and god hehe.

.18 athlon tbirds were the same, AXIA chips were famous for hitting 1.6ghz, and many others were famous for being the dumps.

.18 palominos had their famous chips, AGOIA and AROIA, and certainly had their less popular steppings that couldn't overclock for nuts regardless of how many you tried.


And the same goes for today's .13u chips.

Personally I would see the biggest difference between yester-year's and today's chips are the differences in clock speed. The range of speeds for .25 and even .18 chips was very limited; consider this - a 500MHz pentium 3 overclocked to 700 is already at a 40% clock speed increase. A simple 50MHz lower is still 30% increase. The gaps between different steppings back then were much much smaller, where a 10% difference between high clock speed chips today can be more like 200MHz which seems much more discernable.

Stepping has always been important, no tomfoolery about luck is involved here. Its just that it wasn't nearly as noticeable back then...
 
The point of this thread is that I have a very overclockable processor and I am considering buying an ABIT NF7-s and dual channel pc 3200 and a specialist heatsink. Buying a new motherboard without buying a new processor is very uncommon, and is only done in a strange situation. Is having a very overclockable processor a strange situation?

Buying hardware for the sole intent of overclocking is kind of silly because there is no gaurantee that I will be able to overclock my processor past 2 GHz. Well if i buy the new mobo, memory modules and heatsink only to discover that my processor can't be overclocked to ridiculous speeds, then I will just go out and buy a new processor.

Hell I did that just today actually.. Something I did wrong?
 
well if you didn't think of it as an inconvenience then you didn't do anything wrong.

Took me an hour to get the computer back up and running with everything I wanted on it. Well there's a few things still missing but I'll get around to putting htem back on.
 
your kinda late in the game telling us something most of us knew a long long time ago especially as it's a discontinued chip your refering to.

12x220 @ 1.65 volts is impressive, got any pics, i'm sceptical thats all, 2.64 Ghz is to my knowledge unheard of on air let alone only at 1.65v
 
The main reason i thought of this thread was not to educate you about steppings but I typed up this thread because I want to find out if i should buy the new motherboard, memory and a specialist cooler in order to overclock my processor. The new hardware will cost a couple hundred dollars and there is no gaurantee that my processor will overclock well.

yes you should, there are some really nice nforce2 boards out there and plenty of heatsinks to choose from as well as memory.

what are the codes on your chip, tell us it'll give us a good idea of what speeds it'll go to, also can you remember what colour the die is, green/pink tint etc...
 
I'm not exactly sure of the code of my own 2500+ but it's a brownish tint and I can tell you that it doesn't want to oc for shit. 11x200 at 1.8v and it wont even go. My dad is ordering a 2500+ for himself and I'm going to swap em out hoping that his will oc better.. it's going to be multiplier locked however :eek:
 
My processors OPN (ordering parts number) is AXDA1700DLT3C. I used 'central brain identifier' from majorgeeks.com to find out what OPN my processor has. My processors default Voltage is 1.50 v.

hence the 'L', it's the other codes that are more important in determining how good the chip is.
 
i know it's a crap pic and not very clear but im sure you get the idea.

post everything that is written in the black bit at the bottom.

you'll have to take your heatsink off unfortunatley but without doing that theres not a lot more i can tell you.

I am sure he means 2.46, this is what most of them run at. 2.64 on air is total bs.

my thinking too but 12 * 220 = 2.64 ghz
 
get the DFI infinity or LANParty... they are known to hit 240~260 on the fsb
 
sorry, i've been running on no sleep..I fat fingered that one..
it should read 11x220 for the 1700's..

thats better, i can believe that. still dam nice though at only 1.65v i have to run mine at 1.75 to keep those speeds stable.

have you tried maxing those puppies out, i'll take one of your hands if you got one spare

I haven't have a chance to play with them in my water/kryo system..maybe in the next coming weeks, depending on work..
nope..sorry, not for sale..
 
i got 2, one is in my sig it's been running at that speed and voltage for bout a year (runs 24/7) and the other is in my lan box o/ced to 1.6(limited to crappy mobo) great chips if u can manage to get them
