Newegg selling Throughbred B's 1/10/03

[Shimmishim]

okay

10 x 166 done @ 1.65Vcore

this is an xp1700+ ... will try higher later on...


question for 8rda+ users:

1. should i enable h.d.d. smart capability?
2. set the agp frequency to 66mhz or auto?

i think that's it for now...

If the 1700 and 2100 oc to the same Mhz is there
any difference in performance ?

Could someone post the link to the correct 2100 to buy?

Thanks big time for the help and a great find

Read all the front page links at Overclockers.com. In about 15 minutes, you'll be all up to speed on the latest and greatest in AMD land. The short and skinny of it is you want an Athlon XP 2100+ DUT3C with core stepping AIUHB. The only vendors explicitly selling this stepping is Newegg and PCnut, both OOS until Tuesday (though I would check each night or get an auto-notification, as Newegg often updates that night). There have been reports of the 1700+ DUT3C with core stepping JIUCB hitting 2.3ghz+ as well, but unless you have extreme cooling and are willing to perform a voltage mod to the CPU, mobo or both, don't expect to get much more than 2ghz.

PS I'm not worried about the lifespan as BigJ stated, I haven't had the same CPU in my rig for more than 6mos. in the last 3 years or so.

Silly question, what do you guys do with all your old parts once you replace them with the new ones every 6 months?

Every 6 months?? LOL, it's more like every month. The FS/FT side is there for a reason.

Just found out the TBred B XP2100+ works great on my old KT7 non A mobo without any mods! I set the multiplier in the bios to 10x and lo and behold, I'm running at 2300MHz (23x100). This is confirmed by wcpuid. I'm using a Thermalright SLK-800 with AC3 with YS-Tech 48cfm variable speed fan and they're keeping my CPU cool at 38 deg C. Ran Prime95 and system seems rock solid.

Check this out:

wcpuid - chipset

If you own a KT7 non A running a t-bird, looks like this is a good time to upgrade your CPU. The XP2100+ TBred B sells for $101 and I think it's worth every penny considering how well it overclocks.

Note that the 1700+ won't give you multipliers above 12.5x on the KT7 non A (without modding it at least, you can always solder a resistor between the 5th multiplier bit and Vcc to bring it high) since it's stock frequency is 11x133=1463 and 11 is less than 12.5. The 2100+ has a stock frequency of 13x133=1729 and since 13 is past 12.5, the 5th multiplier bit is set by default.

 

[SharkyTM]

well... i just got back from OC'ing my 1700+.
Results:
12.5x166= max of board (KR7A-Raid) and RAM... 2075MHz
I'm out of multipliers on the mobo, and know from previous testing that my system does not handle higher FSB
SO... looks like im stuck at 2.075GHz... until i do the solderless voltmod.

 

[JWU42]

FWIW - I have to agree with many comments about A versus B. You might pick up a few more MHz versus an A, but nothing too dramatic.

I have a 1800 Tbred A that runs fine at just under 2 GHz. I am one who prefers a much greater FSB OC then simply bumping the multiplier. Mine is running at 189 x 10.5 (1.98 GHz).

I will say that saving $10 on the 1700+ Tbred B (versus the 1800 A) is a good investment since it should go as far or further...

Yo, doc.
That is good news. Is that an Abit board? Which bios lets you do that? Any mods required?
What happened to oveclockers.com? They exceed their bandwidth for the month?

have you done any stability tests like memtest86 or prime95... it'll show you if you are completely stable or not.... i can run my 1700+ @ over 2.0 ghz but it's not completely stable... so i've backed it down a bit to 1.94 ghz @ 1.875V

DOC,
How is your TBred doing on your Abit KT7? I have a KT7 Raid(non A) lying around that I would like to use a TBred on. Do you have a link as to where I can get more info On the multipliers 8x=,9x= etc. Which bios are you using?

I'm using the Abit KT7-RAID (non A) with the latest bios A9_2.34 available at Paul's KT7 FAQ over at Sudhian.com

Absolutely no mod is required on the KT7-RAID non A, which is what got me so excited. Note that this only applies to the TBred XP2100+ though. If you get anything rated lower than 2100+ (eg. XP1700+), you'll need to mod it to get the higher multipliers (13x-20.5x) on the KT7-RAID non A.

Yeah I was wondering too about overclockers.com. Their forums are still up though. Just go directly to http://forum.oc-forums.com

You can get more info on the multipliers at Wes Newell's website:

This website has even more info on this topic, but I've never been able to fully understand what they're saying:

Awesome chip! Running mine @ 13 X 143 = 1911 mhz (2300+ ??) on my K7S5A with 768 MB of PC133 RAM. I just used pencil to fill in the 2 L11 bridge gaps to change the Vcore to 1.85 (Yes, pencil works, I did this too with my old 1600+ oc'ed to a 1900+). Then I used a razor blade to sever 2 of the L3 bridges to change the multiplier to 13. This all took me about 10 minutes. Runs rock stable but won't boot @ 13 X 150.

Can you expand on how this is done or point us to any sites with more specific instructions on both of these procedures?

This sounds very interesting and the multiplier unlock could be very useful to people (like me) who don't have the high MHz ram or 1/5 pci divider.


EDIT

I assume you are talking about the 1700+ and not the 2100+ (or maybe it doesn't matter).

reef barracuda...i have the same k7s5a and the same chip.....i was gunna buy a new motherboard till i read yer post....could you email me or pm me? enable yer pms please if ya get a chance i got a few questions to ask.

 

[yodayoda]

hey guys, got a t-bred 1700+ for $49. checked the serials and it is a t-bred B but a J series, so basically performs like an A. regardless, it is kicking ass in my Abit KR7A mobo. i closed the L1 bridges with a pencil (no burned pits) and it is doing 2000+ with a bump in voltage to 1.65V (just to be safe). kick ass!

These T-bred are unlocked, the bridges are connected underneath the OPGA I did the same thing on my T-bred A back in October, and found out later it was unlocked. Its fine though, no need to get the eraser.

Also, do you remember the complete stepping code? Apparently the JIUHB stepping does much better than the JIUCB stepping. Don't have one myself...so I can't confirm or deny....

[formulav8]

I ordered 2 for someone and they are both jiucb 5102. They both do 2ghz. Doesn't like 2600+ speeds though. Thats testing with a aluminum cooler though. Will get a copper or copper insert cooler and test them out and see if that helped or anything.

i have a 2100+ B Week 1 2003

have it at 2.0 ghz right now... just trying to see how hot it'll get at the moment..

only 1.65V

my 1700+ couldn't even hit 2.0 ghz w/o 1.9V

Same here. I have the same mobo, but only 512 mb ram. Can you give me some help as to what bridges I needed to do. Thanks a million.

 

[KIAman]

I have to agree with JWU42. I still have my 1700+ tbred "A" AIUGA running at 2000mhz @1.725v. Mine went up as high as 2100mhz but temps were in the 50's idle. All this on slk-800. It seems most people who got the 1700+ tbred "B" cant do much better if at all. Maybe the tbred "B" needs more refinement from the fab. My "A" was a week 45 and seems like a very mature tbred "A"

 

[jacky72]

yep, it's unlocked, 178x12=2135mhz @ 1.6v, 38c idle, 45c loaded, I have to open the case to get that temp. awesome chip for $50!

 

[darqice]

anyone with experience oc-ing one of these t-breds on a kt133a mb? IE: the asus A7V133? I believe its possible with a bios update.

ty, darq

 

[RU482]

I got an XP1700+ JIUCB 0250MPMW today, will try overclocking tonight

very impressive




hopefully tomorrow i will be able to try this 2100+ out. leg is getting better

I have been testing my Tbred B for the last few days as time has permitted. Here are my results so far:
Abit KX7-333R rev 1.1 Bios b6
ThermalTake Volcano 7+
1700+ tbred B
2 x 512mb CorsairXMS 3200
PNY G4 Ti4200 64mb
Quantum 8.4 gb 5400rpm ata66 HD (yeah, I know, I only use it for testing)
old DEC tulip chipset 10/100 network card, floppy, dvd-rom, 450w power supply

I have been running at 176x12@2112mhz for 2 days, running Prime 95 and system is stable. This is roughly equal to a 2600+. I have the cpu voltage at 1.725 and the cpu temps are 35-36 C idling and 40-41 C when being stressed. Be advised this is from the thermistor in the cpu socket, since the KX7 does not read the internal diode. Also, the mainboard is not installed in a case, but is sitting on the shipping bag on my workbench. I have a friend with a KD7 that does read the internal diode and he is usually about 15C higher reading the diode than the thermistor. Running 3DMark 2001 SE I get scores from 11247 (low) to 11582 (high). Also, the PNY card is running at 88mhz, since I have 5/2/1 divider. I think there is more there, but not for me. I had to rob the memory from my main system because the Crucial PC2100 I will be using in the system won't take the high bus speeds. This is a bit of a bummer, since the KX7 only has multipliers to 12.5. It has a setting that reads >=13 in the bios that freaks the cpu out, hehe. But since this will be going in my backup system, used mainly for websurfing and email, I can live with it. Pretty damn good cpu for $50. If I push it higher, I will update you guys. Good luck with yours.
BTW, my friend with the Abit KD7 ordered a 1700+ from New Egg this past Monday and also got a tbred b same as the rest of us.
