2200B results

FlailBoy · Sep 7, 2003

After insisting there were no 2200Bs I found out there were and I had to know.

FIC AN19E (kt400)
xp2200B AIUHB 0251 1800 stock
512mb Crucial pc2700
Vantec aeroflow~41c load.

Got the thing to 148x13.5 primestable at stock-1.60v,~2000.

That was about it. I upped the volts, went up 1mhz at a time, swapped out the memory just in case...

Max stable on this chip seems to be just over 2gb. It's not temps.

This thing doesn't seem to overclock any better than a 2200A.

Running it at 166x12 right now.

Anyone else have better results?

first 2200 B i heard of so far =d hehe i think you're swimming in uncharted waters =d

Fever · Sep 7, 2003

I saw a 2200+ Tbred B before. It was an AIUHB 0248, I almost bought it but went with my 2500+ AQXEA 0321. I don't understand why you're only getting 2GHz..

Because
1. He needs 1.8 volts Vcore.
2. He's probably using a no name power supply since it's not in his sig.

Can you post your wcpuid info and the stepping info for this chip?

1. He needs 1.8 volts Vcore.

Ok, I didn't try going that high. Thanks I'll try that and let ya' know. Was able to get to 2.2gb+ w/ my 2100B on 1.675v so I was hoping for better things.

PSU is a generic 350w but I think it should be up to the task.

Will tweak for a couple days and post more stuff.

i have xp with these chips as i have 3 systems with them my dads my sisters and my grandmas all at 2200mhz stable at 1.8v-core u gotta give these chips some volts to get them going i had 1 at 2400 mhz but needed 2volts to get it stable and my slk was not up to the task of keeping it cool so to get them high u gotta give them the volts hope this helps

FlailBoy · Sep 10, 2003

Yeah, it does seem like this is going to be a voltage-hungry chip. Got it running stable at a couple different combinations (154x13.5, 166x12.5) at just under 2100mhz, but it took 1.70v to get there. Might try to do a burn-in at this speed and then see if I can nudge it up a bit more. If not, I'll keep pumping up the volts.

He-he. you're easy on that whip aren't you?
1.7 volts is not exactly runnin's some current through it, is it?

It's interesting to see the two sides of Vcore approach. In another thread right now, I'm having a discussion with a guy that thinks 2.1 volts is standard overclocking procedure (!).

Over 1.8 is pushing it of course but you need at least 1.8 to start complaining about "my chip won't OC as high as I had hoped."

EDIT EDIT EDIT

I changed my mind on this one because no one offered a convincing counter argument to hitechjb's thinking:

1. Assuming expected CPU life is 10 years, 30% overvolt statistically reduces it to six years.

2. 30% overvolt for DLT3C's is 1.95 volts and for Bartons and DUT3C T-Breds, about 2.1 volts. (Remember to keep the on die CPU temperature under 65 C.)

3. Highest attainable stable Overclock will not be reduced within months provided on die CPU temperature is kept under 65 C.

hitechjb:
A 10% increase in Vcore, would shorten the failure time to 83% of nominal failure time.
A 20% increase in Vcore, would shorten the failure time to 69% of nominal failure time.
A 30% increase in Vcore, would shorten the failure time to 59% of nominal failure time.
A 50% increase in Vcore, would shorten the failure time to 44% of nominal failure time.

Nominal failure time is assumed to be 10 years at default voltage.

I have a generic 300w and it pushes my 1700+ fine at 2.25ghz, temps (and the fairly bad stepping) being the limiting factor...

... so yeah, up your vcore and you should be all set. Also remember to always have your FSB above 160 or so to prevent the 4/1 divider from kicking in.

FlailBoy · Sep 10, 2003

He-he. you're easy on that whip aren't you?

LOL

Pretty much. The rig in my sig was my first ever O/Cing attempt and I got great results off puny voltage. Guess I got spoiled. I really wanna' see what this chip can do so...in for a penny...

Definitely shooting for running at 166+ times something. Was just messing around with different combos.

Duner · Sep 10, 2003

I had a 2200 tbred b. It was an AIUCB DUT3C. It did 180 X 11 = 1980 MHz at stock 1.6V. It would do 180 X 11.5 = 2070 MHz on 1.68V. I didn't have a good enough power supply to take it any further. All in all, not a very good overclocker, but it wasn't a great stepping either.

Tyranos · Sep 10, 2003

You should raise the fsb some more to overclock the memory. That isn't crappy ram so I wouldn't worry that much. Raise that vcore to 1.8 and see what you can do.

(v)estra · Sep 10, 2003

well i cant say anything i cooked mt 2nd 1700+ today

back to my 2200+ 1.85v at 2300mhz

im so tired of chips that cant handle voltage they need 1 that will hold 2 v stable and never cook

at 1.9v with my 1700 i was@ 2550 then i tried for 2600 and now its got a nice burn mark on the chip and wont do anything

o well so much for that might try the 1800+ or go wild and get the 1700 notepad chip that 1.2v stock sounds nice and i was told that they work in desktops

so lets see at 1.5 im looking at what 2300 mhz i hope (hell who knows can u say barton 3200

wishful thinking

PSU is a generic 350w but I think it should be up to the task.

I now no longer think so. Got the chip running at 166x12.5~2083 @1.70v. Would run prime for about 1 1/2 hrs before erroring out. Was watching the CPU voltage (Speedfan) and even at 1.70 it would dip below every now and then. No way I'll get consistent output any higher than that. PSU is a pile o' junk Codegen. I have another PSU that's pretty honkin' so I'm going to swap that out and try again. Should be able to get to that this weekend. Will post results asap.

Arkaine23 · Sep 12, 2003

I just scoped a tray full of CPU's at a local computer shop. they had several 2200+'s, and all were either old AIUHB's (0244 or older) or were AIUCB's. While other models were all recent weeks, as late as 0333. Seems AMD has decided 2200+ is to be the junk model of Tbreds, why 1700+ and 1800+ are the pinnacle of Tbreds.

FlailBoy · Sep 15, 2003

Ok getting there.

Swapped out the PSU for an Enhance 350w from another case. Specs- 28A on 3.3v, 30A on 5v, 15A on 12v.

Seems to be doing better. Running right now at 174x12~2098mhz. 45c at load on 1.725v.

Was able to get 169x12.5 and 175x12 running prime95 for about an hour each before it errored out also @ 1.725v.

Memory is still at stock volts, 2.5-3-3-7.

Will keep ya' posted.

FlailBoy · Sep 17, 2003

I think I hit the wall here. Ran 166x13~2160 @1.80v. Went back down to 166 because I wanted to make sure the memory (Crucial pc2700) wasn't part of the equation. Ran primestable for about 3 hours before erroring out. 46c load. Tried a few combinations in between w/ voltages between 1.725 and 1.80.

Nothing ran prime for more than a few minutes in between about 2098 and 2160 at any voltage less than 1.80v and I was able to get to about 2100 w/ the new PSU on 1.725v so that was pretty much a bullseye-good call.

However my conclusion on (this) 2200B is that it's a pale imitaiton of some of its little brothers. Took an extra .075v to get 60 more mhz. I'll try a few more combos over the next few days but so far I think the best configuration I've found has been 174x12 on 1.725v. If I find something better I'll post it; but this chip is really kind of a dud.

My .02 (actually, my $85).

And the answer is...

Saw another thread out here about what to get to replace an xp2200.

My final answer is: just about freaking anything.

XP 2200B AIUHB 0251

Replaced mem with a new stick of Crucial pc2700 (Had been getting a few freeze-ups even at stock before I ever tried to O/C anything. Got it running stable with a stick of PNY 2700 so was able to conclude at least that I had a bad mem stick). No help.

New PSU-Enhance 350w Specs- 28A on 3.3v, 30A on 5v, 15A on 12v. Plenty.

Same mobo FIC AN19E

Good cooling-45c at load.

I don't care what you do to this chip-went all the way to 1.80v-this thing won't run stable at over 2.1ghz.

Running at 174x12~2098 @ 1.725. After a couple weeks of tweaking, this still seems to be the best I've achieved so far.

300mhz is better than a sharp stick in the eye, I guess. But not bloody much.
