xp1700+ tbred revB WOW!!

[Boonesmi]

about a week ago i bought this cpu from newegg (out of the refurb section for $35 shipped)
im not sure how much luck others are having, but dang this is one incredible CPU!!!!

first off i just installed it and booted up (i run an epox 8k3a+ with 512mb pc2700) so it was just running at the default of 1700+... i decided to see if this thing could overclock first i just increased the fsb to 166mhz ,xp2200 speed, and i ran some games and let prime95 run all night with no problems

when i recieved it i noticed it was factory unlocked since the bridges were not closed, so i increased the multiplier from the default of 11x up to 12x (bringing it up to 2ghz)... again the thing was rock solid stable!!!

but i noticed it was running a little warmer then i like so i decided to under volt it and yup again it runs no problem (the tbred B default voltage is 1.6) this is running 1.4vcore


so for the last week its been running totally stable (even while gaming and dvd encoding... not a single crash) at xp2400+ speed, 2ghz, all the while being undervolted by .2v to 1.4vcore, the temp stays in the low 40's at idle and get up to the high 40's when gaming.

*** update 1 ***

i decided to try to find the limit of this cpu, so first i had to find the limit of the fsb (since at 166hz fsb i was already maxing out the multiplier limit, it is unlocked giving me full range of 5x-12.5x but without a 13x and higher i would need to increase the fsb higher then 166mhz)

so i lowered the multiplier and increased the fsb, i could only get to 175mhz fsb... once i found the fsb limit i just kept raising the multiplier. i was suprised i was able to get all the way back up to 12.5x, ohh by the way i did raise the vcore up to default of 1.6v

so... the end result is i still dont know the limit of the cpu at this current speed the motherboard post screen identifies it as an xp2600+ but its actually running 175x12.5 or 2188mhz

i really dont want to unlock the 13x and up multipliers since i then wont be able to run it where i intend to keep it on a daily basis of 166x12 or 2ghz, but without the higher multipliers i wont be able to find the limit

but its kinda cool that it will run at xp2600+ speeds while at default (or lower) voltage

good job!

Lucky guy. Nice overclock.

Boonesmi... nice OC...

Gave me food for thought...? I eased my XP1700+ down to 2Ghz (9.5X210fsb) and lowered the voltage to 1.6 (stock for this Tbred B) and to my surprise its rock solid stable...? Plus its even cooler than before (duh... ) I figure the small sacrifice in Mhz for the decrease in heat and voltage makes more sense...? I may try going a little lower in voltage just to see if it will?


BTW my voltage before was 1.750 and temps were 102-104F (idle) now at 1.60 & 94-95F (idle) I`ll try 3dmark2001 & prime95 together to see what the full load temps are...?

That's why I keep my 0302 at 2050 @1.65V, Bartman. It's plenty fast, yet runs nice and cool!

kewl,

im hoping i have some luck overclocking my xp2100 when i get it at the end of the week.

you really got a bargain for $35.

 

[Duvie]

$35.00 dollars in hands down the cheapest 2ghz anyone is going to find...the fact it is so undervolted makes me think much more could be there for you with some vcore and much better cooling....Push it!!! Push it!!!!

 

[Boonesmi]

i actually bought 2 of them, they were each $35 shipped

when they got here i checked the #'s and they were both the same. both revB with the same code, even manufactured the same week. i havent even tested the other one yet, but i kinda doubt it will overclock as well as the one i installed


as for the "limit" of this cpu.. i really have no idea, i never even tried to run it over 2ghz (2ghz seemed like such i nice round number)
hehe but now im starting to wonder what it will do, tomorrow i may have to try to find the limit of this ah heck

 

[Boonesmi]

ohh by the way incase anyone is interested the codes on both cpu's are
AXDA1700DUT3C
JIUHB0302WPMW

 

[ChampionAtTufshop]

JIUHB are the "good" oens
ive got a JIUCB that tops out at about 1.9ghz but with 1.85vcore (1.9v actual thanx to asus lol)
but it does 1830-1850 all day at 1.7v (1.74v thx to asus) so thats where i leave it

ive seen a few JIUCB that are good, but generally the JIUHB are better

 

[PhoenixOfWater]

Nice OC!!! and only for $35 :Q
Just think of how much money you saved

 

[Blooz1]

Hmmm..the ID on my chip is very close to that:

AXDA1700DUT3C
JIUHB0302XPMW

I should do some experiments and see if this chip would do the same speed at lower voltage than the 1.65 it's at now...

 

[Boonesmi]

updated my original post

but im still not able to find the limit of this cpu since my boards fsb is maxed out(well its actually probably the ram thats limiting the fsb since most 8k3a+ boards can get a lot higher then 175mhz)

 

[CraigRT]

Thats a killer OC... my god!!

I want one of those chips so bad! wait, i had one.. but my old KT266A board won't take TBreds... I had to sell it..

I'll get one again!!
