At last - A wonder chip!

Well, not since I managed to get an AXIAR 1000 "K" up to 1800mhz on air have I found a wonder chip. That was now nearly 2 years ago.

Well ive found one again. Ive picked up now my third XP2100 AIUHB 0250. My first chip did 2133mhz @ 1.6v (default) which was a pretty impressive turn out. It was a brown package chip. Having seen other people hit these clocks though it struck me that the chip was nothing but average (maybe even slightly below average). So I picked up a second. This one was slightly better, same code, same colour package and did 2166mhz @ default volts. I didnt bother posting about it as it was not significantly better than the first to require a new thread. However, now I think ive hit the magic chip. Its taken me to the edge of my air cooling ability (alpha 8045!) while using DEFAULT VOLTS. Absolutely incredible. Its another AUIHB0250 '9' but this time is in the Green package format.

With this new chip I have booted at 2500mhz using DEFAULT VOLTS.

I have been prime proofing at 2250 overnight using -0.025 below default volts (1.58v) and it was still going this morning. Incredible!

As I bump up the speed and vcore I will continue to update this thread with screenshots, but for now I'll merely tempt you with this :

Whats the 4 letter code after the week/year PiLsY?

Very.... very sweet oc man!!! Congrats :)

I can ship you one from the US.. (well a newer production date though). PM if you want to.

Hmm what would such a CPU cost me ? i think the 1800's are about ehh 75euro's here ... not sure howmuch a 2100 Tbred would be though

WTF have AMD made a mistake and rebadged the wrong CPU's or something :D

Thats like an XP2400 and then some for free! :D

Nice speed on air. I wondered what you were doing up at 7am on a Saturday morning browsing the forum :)

These new AIUHB 2100+s are making my AIUCB Xp2400 at 2200@1.85v stable look a bit sick :( Did you get it from your trade source in the UK or from a standard online reseller ? Normally we get stuff which is fairly old, week wise.

I hope this new found overclockability is taken over to Barton, it should be, they are charging enough for them.

Regards

Andy

No nothing special - just a standard online reseller m8 :).

Given that getting stunning chips is just pure luck I figured what the hell and just bought the cheapest one I could find ;).

Next step....

PiLsY.

Damm impressive m8 ;)

One thing wierd tho, you get 50ºc temps with 1.6v and a 2.9k rpm...uhh not very good

Hmm, temps do look a bit high like Rudzer said, but they are load temps by the looks of it. Still a very good chip by the looks of it!

Very nice!

Hello all,

Been reading these threads for a few days now. Just like to say nice one.
At last some excellent chips are appearing for peeps who just use good aircooling :p

Yo PiLsY
Which on line retailer did u get ya chip from. Ive got a friend looking out for some of these chips at computer fairs but if you could pass the info on to me I may look into gettin one online.
How much did you pay for it also, im gonna have to shift some gear depending on the price.

excellent overclock, happy for ya

Just a brief history.

first chip was a tbird 1.4 highest overclock managed to just hit 1.8
second chip XP1700 Palomino highest overclock 1935 mhz
third chip XP2200 tbred -A terrible overclocker @ only 2050mhz
4th chip XP1700+ tbred-A highest overclock 1989 mhz

All these overclocks have been on air. I have a thermal glaciator II with a Delta screamer on. Good cooling IMO. Got a variable resistor connected to it though so i dont have to hear the Delta 24/7

:D

Thanxs 4 da replys

Shops you may want to try for B stepping Tbred 2100's are :

www.tekheads.co.uk
www.theoverclockingstore.co.uk
http://security.cclcomputers.co.uk/acatalog/
www.overclockedpc.co.uk

Temps are not too bad considering I have only 1 2000rpm case fan and that was after a solid 12 hours of load via prime.

19c above case temp after 12 hours of full load and a silent pc...

Well im not complaining :).

This cpu does seem to be running hotter than the brown 2100's I used though. By maybe 4c or so under full load?

Ive hit a problem now though in that it freezes in prime at anything over 2300mhz no matter what voltage.

My bets are on this damned 8RDA+. Possibly the PSU since ive swapped the original Enhance 460 out and am now running an HEC 425watt (true wattage only 350 though).

More playing over the next few days to try and solve it.

PiLsY.

Cheers man,

Sorry to hear you are stuck at 2300mhz, im looking into gettin the 8RDA+ but have seen the issues many people are dealing with.

Are you not able to tell me the store you got YOUR chip from?
The links you have posted I already have access to plus many more :)

But i wanted to specifically know where you got your chip from.

Hope all goes well for you

L8rs

I got it from CCL :).

I listed a few as these things are going like hotcakes. If its your first order from CCL then it will be 2 - 3 working days before your order is confirmed as they fraud check all their first customers. This may mean you miss the current stock.

All the above listed shops have the XP2100 Tbred B in stock now, so I thought id list em all :).

PiLsY.

[EDIT] Looks like CCL are sold out. Tekheads would be the best bet after them. Ive never been too impressed with OCS service. A few times theyve told me one stepping cpu and sent another, then claiming they dont guarantee steppings. Best avoided unless a last resort. OCPC get their cpu stock off tekheads.

CCl wow, yes ive dealt with them a few times be4,
Thats very suprising!!!

Im gonna wait to see if my friend finds anything at a computer fair in nottingham tomorrow. If he dont then looks like i will be indulging in some online shopping

:D

After this abysmal xp2200 tbred, i need something nice in my system.

Where you able to get any sort of confirmation from them about the stepping, or was it hit and miss.
Have you not got another mobo there, which you could try it on. It seems strange that you cannot get over 2300mhz seeing you could get to that at default voltages. Im having second thoughts about gettin the epox brd. Alot of peeps seem to be having problems which epox are keeping quite about

:rolleyes:


Hope you make a breakthrough with da chip
L8rs

that truly is a wonder chip!!!!

I've bought 3 CPU's from CCL, first two were palimino AGOIA cores and the other one was a Tbred 2400+ which was AIUGB, still both very good steppings.

Well just looked @ CCL website,

their online store aint showing any xp2100 tbreds so i may have to give them a call.
Hope they aint run out already.

:(

Amazeing overclock


I have a green week 50 here to try out. Hopefully i will have similar results




Jen

PiLsY, can you post the full stepping?

Not without taking the alpha off which is a right pain in the arse :).

Heres the main parts...

AIUHB 0250 '9'

Dont think any of the other bits matter tbh.

I'll pull the heatsink off and post the full stepping up when I replace the PSU :).

PiLsY.

Niiiiiiice!!! Pretty sweet getting a chip like that Pilsy.:thumbsup:

Come on ripp that Alpha off and tell us your full code ;)

Our 2100's are B cores, but we don't have many left. I assume all future batches will be B cores now too.

Our 1800's are still A cores.

1700's are discontinued, stock will disappear of those.

OCPC also have some B core 2100's in, we sold him another batch today.

I just ordered a Athlon XP 2100+ AIUHB 0250 from ExCaliberPC. I hope mine does as well as yours.

I can vouch for Sam and tekheads. I have another 2100+ (green AIUHB 0250 '9') sat here to go in a m8s PC. This one isnt quite as good but its close. 2183mhz @ 1.6v. Bought from Tekheads on Wednesday afternoon. Asked for the stepping, the guy nipped off and picked up a 2100, confirmed it as an AIUHB 0250 and sent me that exact cpu out of his hand. Arrived 8:15am next morning. Cant argue with service like that :).

PiLsY.

[PS] Is my tenner in the post Sam? ;)

Hey PiLsY, did you try how high your chip would go? I've been seeing alot of the lower Bs hitting 2.5Ghz with low voltage, but after that they can't go much higher, even with 2.2v. It seems like the headrooms of the lower Bs and the higher Bs are different:confused:

Thats a nice OC Pilsy, keep up the good work!

Im looking for the 4 letter combination after the production date. There has been speculation those with MPMW provide 2.4 - 2.5gig quite reliably, and those with VPUW are able to scale above this, even with aircooling.

VPUW sounds familiar.

It definitely had a U and a W in anyway....Although I seem to remember a D in there somewhere as well.

PiLsY.

What is the point here????

He is running as low as 31C... Or Either his computer in under snow outside or with a air conditioner direct to the case opened.

:D :D :D

uhm.... a system temp of 31C is a pretty warm room actually ... his CPU was at 50C load


However, PilsY, I'm getting impatient on this end ... give that CPU some stick would you? :D

Its in the Prometia.....

Whats the highest CPUID for an AMD on here yet? I may be in with a shot.......

I cant seem to run Prime95 at any speed over 2298mhz. The next step up, 2306 locks up after 10 tests or so, 2309 locks up the instant I click torture test. However, ive now been running folding, playing games and generally fooling around at 2880mhz for 46 hours without a reboot now with no sign of instability.

Problem though - the highest I can get the board stable is 222mhz. Highest multi I can use is 13x. Im maxed out :(. Have to drop to 218mhz to use dual ddr as well, so an even bigger loss.

Is there any way to get the high pull multis working (13.5x and upwards)? Im still only at 1.7v here.....

PiLsY.

hmmm noticed the same thing, Prime wont run at all well but I can fold or play games all day long without a problem...

screw prime is my opinion

BTW, checked your stepping? -VPUW right? :(

Hey PiLsY, could you check your PM?

One question.
I am getting an 2100+ AIUHB very soon, maybe tomorrow, so I was wondering, what are the main "ingredients" of a good OCer ?
The CPU will definitely be AIUHB, maybe 0248 or 0249 or even 0250 if I can wait one more day.
Does anything else matter much, such as color, ?

VPMU after the Production date seems to stand among those 2.8gig results :(

Still not pulled it apart....

Will do it tonight after work :).

PiLsY.

I finally killed one of old CPUs and oredered one of those CPUs!

I hoping that I get the correct stepping. I am calling the vendor but, doubtful that newegg will pull my CPU and tell me the stepping.

I will post again this week with results on air - Volcano 7+.

Praying for results nearing Pilsy's but realizing I will probably be short.

Thanks for the links mate ! been looking for some new shops! Any comments about service quality and such



/Thread hijack :smileysex

OCPC im not sure of m8. On the one hand Jess seems very helpful, on the other nothing ever seems to come of it. We shall see.

The other 2 I have no hesitation in recommending - superb stores.

VGI are also a long time favorite of mine due to the customer service. Theyre more pricey than most places (but only by a couple of quid) but would move heaven and earth for you if you asked.

Full cpu stepping...

AXDA2100DUT3C
AIUHB0250XPAW
96075987 (may have missed a couple of numbers off there but that bit isnt important anyway :)).

Note the XPAW.....never heard of that one before.

PiLsY.

PilsY

I've seen XPAW before ... had a Palomino like that once even (2100+ too)
I have a 0250XPSW (2 of them actually) and they both suck a$$ :(

I cant see the pictures... plz tell me your top atm ! :)
I've also an AIUHB 0250... default voltage going to 2260!

To be fair I dont think these 4 letter codes have much to do with the ocing. Theres so many different combos of them it could be something as simple as a code for the day and time of production. Certainly nothing to do with speed binning otherwise wed see the XPAW and XPSW chips returning very similar results.

Still down to pot luck imo.

PiLsY.

Well, got a week 50 today, and so far i've managed to get 2280 (175x13) at 1.6v (prom cooled), in a kd7-raid .. let's see where this guy can go. So far is looking promising.

That is a great overclock for air cooling Pilsy. I picked up a 0302 greenie 2100+ from newegg the other week I am amazed at how well it can overclock. Right now it is running at only 2015 at stock voltage and only 26 degreed C at load! The mobo sucks for high fsb and can't go any higher than 155mhz because when you turn off the pc, the bios resets it back to 133. Very poor mobo. Stay away from Gigabyte

I tend to agree with PiLsy's wisdom.

I finally ordered the 2100 from the egg.
I JUST installed 3 PCs on my home network for folding.
I put that cheap amd hsf on one of my CPUs.
I was at my desk when it popped off and the CPU fried.
I will not make that mistake again!

On the bright side I ordered this wonder chip and a Volc7+ to keep it cool.
It should be here tomorrow and I will share its ocing ability and get back to full force folding.
Thanks for the recommendations and reviews on this CPU!

Thank you. I wish all the ppl who ask what their stepping chip will do before they test it would read this. You can't possibly look at a Tbred B's label & be sure how its going to clock...you can claim you have an idea, but you have none :)

Talk about lousy luck, I just bought one 2100+ AIUHB 0248 MPMW and it only does 2GHz at stock voltage.
Air cooled, but doesn't matter.
I was hoping for about 2300MHz, because a guy got one AIUHB 0249 MPMW from the same shop and he got 2300MHz at 1.70V.

I just received mine from Newegg and it runs BMs at over 2.2Gigs at default voltage on air cooling. I only tried going higher once and it appeared to not like 2.3G even when I bumped up the Vcore to 1.75.(booted to Windows ok but, BMs shut it down) Since it is new I am not going to pound away at finding its peaks, yet. I am going to leave it at 2.2G for awhile and run folding 24/7. So far it is quite evident that this chip overclocks much better than my 2200 T-bred and cost me a lot less.
For the air coolers out there, I'd like to point out that the Volcano 7+ works very well. It is a lot quiter than I expected. I did take the time to lap it before install, so I could see my self in its reflection.
Man this tinkering is funtastic. :banana:
Time to change my sig!
