Just got my 2400+ today. This is the first setting I have tried as of yet, I just got this cpu this afternoon. THis is the first setting I have tried (166 x 15)= 2503Mhz
http://www.oc-athlonxp.com/web_images/2400/2503.jpg
I'm cooling it with a Vapochill. The evaporator temp. is at -8C, cpu @ 1.9v. My 2000+ @ 2.0Ghz, 1.96v was -4c. This chip with out a doubt runs cooler.
I'm running it on a Abit KX7333-R mobo. I don't know the revision, the sticker is on the back of the board and I don't feel like removing the tray. But I flashed it with the newest B6 BIOS.
I assume the multipliers are unlocked for multiples greater than 12.5, but there is only a multiplier option for ">13" in the bios. I cannot choose 13, 14, 14.5, etc. With the ">13" setting, the multiplier reverts to the chips default multiplier of 15. Does anyone know how I can specify the EXACT multiplier? I'm guessing (like everyone else) that connecting the 5th L3 bridge will unlock multipliers 12.5 and below. I'll try that later. I want to see how far I can get on the 15 multiplier first.
Oppainter has a KD7, which is apparently able to manipulate multipliers above 13. The KX7333 apparently is not able to.
I should be able to attain in the neighborhood of 200Mhz FSB, as I am running 1 512Mb module of Corsair XMS3200CL2.
Let me get back to expirimenting here :-) Any comments and/or advice is greatly appreciated. Sorry for the cross-posting, but this is breaking news ;-)

Here are a couple more benches. I'm holding off on the memory bandwidth benches, Q3A, and UT2003 benches, as this is not the FSB I want to be at. I'm going to have to unlock this chip to go higher on the FSB. I already tried 2.6Ghz without success. I don't want to go any higher on the vcore for the time being.
I could score a lot more on 3dMark with a higher FSB. This is only at 166Mhz and the Radeon9700 Pro is at STOCK core/mem settings!

Good work. Can you confirm something for me? Does your XP2400 have the L1 bridges laser cut? I ask because we are working on an issue facing the Kr7a owners. Abit has said the board will not work with the XP2200 and up cpus, but we know that the L3 #5 bridge closing allows 12.5 and lower multipliers. Abit apparently will RMA the board for $25 to make some type of mod that will allow the board to boot with XP Tbred revision B cpus, but it will then be permanent in that you can't use any other cpu if you mod the board. We were trying to find out the nature of this mod for a while.
Our our Amdmb.com site, someone (who may be an insider at Abit tech support trying to help..not sure) said you have to LOCK the cpu to get it to post in its fixed multiplier or you can do several board mods to accomplish the same purpose without messing with the cpu.
http://www.amdforums.com/showthread.php?s=&threadid=161655
The posts relating to the cpu and /or board mods are near the end of the thread with pictures.
The XP2200 has no laser cuts on the cpu L1 bridges, and it has been confirmed by others (not me) that the L1 are closed. If they are closed, at least with regard to our Kr7a boards, we have open them (or at least two of them #4 and #3) if the person who posted these solutions is correct.
The cpu that person showed as an example in the pictures was a 2400+

emtp563,
Those CPU socres are very impressive. I'm curious on how well my P4 2.8 compares. I think its pretty close even with me at almost 3.6ghz. At stock on the card though I score roughly 16.5k on 3D but this is with memory at 453MHz. I could use 1:1 to really compare with you.
I have been wanting to get a new AMD chip.

Here's a link to my 2.8 at 3.51 Ghz and yes the scores are fairly close. Can't wait to see what you max out at and how well it performs.

Nice job emtp563 but don't u think that a 1.9V is almost the end of the CPU capability?
emtp563
10-05-2002, 05:12 AM
Yep, I ran a 2200+ at 1.96-2.0v for a few weeks. It flaked out after about a month at that vcore. I'm really leary about increasing the vcore any higher. Maybe if I had a Promethia. We'll have to wait and see what Oppainter and Mr. Icee can do with theirs.

errmm 2.5ghz 1.9v on a vapochill
like crazy ????
on the reviews we were earing stuff like 2.4~~2.5ghz air cooled :\
lets wait untill the pros (OPP , MrIcee) get a tbred B

10-05-2002, 06:24 AM
Thanks much for the picture. It was speculated that the tbreds in production would have cut L1s. So for us Kr7a owners, we just have cut L1s to lock the cpu at its preset multiplier (or that's the theory). Abit just released a new bios for the Kr7a which goes backwards, but maybe is the first of a new sequence of bios versions for Tbreds.

Nice work Empt:)
These cpu's are looking very promising..as your benches completely show. I think a few days of burnin does these T-Breds a world of good too...I gained nearly 150Mhz on my top clock of my present 2200+ by upping cpu and voltage a little at a time. I never made 2500Mhz with the 2200 but came damn close at 2479mhz. Keep up your great work and testing..and keep us updated on your progress:)

Just a note on the voltage. I'm running this 2200 solid at 2344 so far useing 1.98vs so I think these chips will handle with good cooling.

Keep in mind guys that Opp and Mr. Icee have Promethia's. I have the original Vapochill. THe Promethia's cool at least 20-30C colder than my Vapochill can get. I'm sure they will blow me away soon enough. Let me enjoy my 15 min. of fame while I can :-) I can't do öööö to this chip all weekend, as I have to work. I'll be off from work next on Monday, I'll have this chip partly burned in by then and maybe I can squeeze another 100-150Mhz out of it.
p.s.- do you actuially think AMD gave all the reviewers the same chips they sell you and I? I think not. The reviewers get hand-picked "cherry" chips. If all the reviewers got bum cpu's that didn't OC worth a öööö, I for one would not have bought this. Would you?
Nice job man. That is a killer system you ahve there. Can you post a 3dmark score so I can see how it does.
Doh sorry there are the scores this stupid 56k connection gets me everytime.

@empt563: Great! You've given me my confidence in AMD back! :D
Any new findings concerning the KX7-333R multiplier issues? Did you get the 13x-18x multis already? Or only still the 15x!?
emtp563
10-07-2002, 05:39 AM
Just 15X. There is no selection in the bios to choose an individual multi. >13. I can unlock the cpu giving me multi's 12.5 and below. The only multi. that would be of any use to me would be 12.5 But I know my hard drives can't handle that FSB. Any lower multiplier would get me below 2500Mhz. I'm going to have to get a KD7-RAID.

BTW: Any Megahertz improvements on your XP2400+ ? :)

Yeah, the 2400+ is 2.0Ghz, I have mine oc'd to 2.5Ghz. Got a 500Mhz OC out of it. I an POSITIVE the Abit AT7-MAX2 and the Abit KD7 can handle manipulating the multipliers. I know people who have these boards and it's confirmed by them (Oppainter for one).

What hard drives are you running with that? I wonder if my WD 8mb buffer 100GB would handle 2500mhz on my KX7333?

Yeah saw a few days ago that OPP got an 16 multi with the KD7.

I have one on the AT7MAX2 and all multi's are available.
I am only using air (slk-800) at 1.8 or 1.9 max voltage and the cpu starts to crap out at a bit over 2250. It is the same exact markings as the one above, so it looks like it really needs some better cooling to get anywher near 2.5, and yes I do think the reviewers had hand picked chips, even though they were older steppings. They were a different stepping aiuab. Ours are aiucb. Maybe the binning for 2600's has effected this. It will be interesting to see if the 2600's can o/c any higher.
Bummer man only 2250 out of the tbred b core. I would be extremly pissed if I were you. That's why I'm waiting for Barton to upgrade this system but my next system could very well be a Intel for the first time in a years if AMD doesn't get their öööö together. I was expecting to be running a barton core at 3g by now...
