Well the 2100 T-Bred Athlons are just starting to trickle in here in Australia and I want one. I have managed to locate a source of "aiuhb 0302 wpew" T-Breds. Now I want to know if these ones are any good for overclocking before I buy one.
This is the T-Bred I am looking at not the Palomino. I already am running 2100 palomino now. I want the T-Bred because I want to overclock it. I have been looking around and it seems that the top 2 overclockers are the week 48, 2002 T-Bred 2100`s and the week 02, 2003 T-Bred 2100`s coming in second. This is the week 02, 2003 I am looking at. I have read dozens of reorts of getting them up to at least 2400MHZ on air cooling alone at default voltages in some cases but mostly avarage of 1.75V over the 1.60 default. (Thats 2400 true Mhz NOT performerhertz) I have ordered a 2100 T-Bred and will see how it goes.
I have never seen a T-Bred A 2100 to be honest. I knew there were a few 1700 and 1800 T-Bred A CPU`s but as far as I had heard I only knew of the T-Bred B and Palomino 2100. I am not saying the 2100 based on the T-Bred A dont exist but I had just never heard of them. Anyway this one is a T-Bred B 2100.
I finaly managed to get my hands on a "AIUHB 0302 WPEW" 2100 T-Bred B. I did not bother unlocking it so everything is done at 13x multiplyer. (If you want to skip the epic story of me and my overclock just skip ahead to where I have my final results.) I just chucked it straight into my Epox 8K5A2+ Motherboard in my Koolance PC2 watercooled Case put a bit of Arctic Silver 3 on and started experimenting straight away. The first thing I did (And I do mean the very first thing, Before even finishing the first POST) was go into setup and straight away put the FSB up to 166Mhz WITHOUT changing the voltage. It was happy with that. Windows booted and I used it for a while 100% stable. Even ran flaskmpeg encoding for a while no worries. Thats 2158 true MHZ at default voltage. I tought fine so I went up a bit more. Got it running at 2340Mhz (180Mhz Bus) but I had to push the voltage up to 2.1 volt and it still wasnt stable. I wondered what the problem was. I have since found out that I seem to be at the limit of the bus or ram. I am not sure. or it might be a combination of the CPU Ram and Bus all adding together to cause this unstability. But I dont think I have reached the limit of the CPU. Anyway I backed down to 175.91Mhz Bus at 2287Mhz CPU speed with the hardest possible memory timings and it is rock solid at the moment. So my FINAL RESULTS are this.
My exact hardware that is relivent is
Epox 8K5A2+ motherboard
Athlon T-Bred B CPU stepping "AIUHB 0302 WPEW"
Corsair XMS 3000 512Meg DIMM
My overclock results are (All in true MHZ and at a Multiplyer of 13X)
2158Mhz 166Mhz BUS Hardest possible memory timings. CPU Voltage at default and memory voltage at default. Around 43 derees C temp at idle. (Sorry didnt check under load.)
2275Mhz 175Mhz BUS Leanest memory timings possible. CPU voltage 1.85v memory voltage default. Around 48 degrees C temp at idle. 52 at 100% Load.
2287Mhz 175.91Mhz BUS Hardest possible memory timings. CPU Voltage 1.85v Memory Voltage 2.70v. (Plan to try 2.60v will let you know if that works.) Around 48 degrees C temp at idle. 52 at 100% Load. This is what I plan to keep it running at on a perminent basis.
I am now a full supporter of the 2100 T-Bred B. BTW if anyone wants to know I got this from auspcmaket.com.au. Ordered it on monday after noon(yesterday) and it arrived 8AM this morning. Cant complain about that.
By the way the I just checked and the current room temp is 29 degrees centigrade. I hadnt realised it a that hot but there you are.
It's all good. I'm currently runing my XP2100+ at 2250MHz (166 x 13.5) rock solid in an Epox 8k9a2+ with 512Mb of Corsair 3200 XMS. operating at a relatively cool 44 degrees (room temperature 28 degrees) under a Zalman CNPS6000Cu. I assume there's more room to play. I set it to that from the first boot and haven't really had the time to play around with my settings. definetly an excellent value for money CPU.
I agree. Though I have seen several reports of XP 1700+ T-Bred B`s going to 2.5gighz (Yes 2500 TRUE Mhz) on just air cooling alone and 2.8Gighz (Yes 2800 TRUE Mhz) on modorate water cooling on a hardware site here in australia. So I think they are slightly better value than the 2100`s. But still the 2100 is perfectly fine for what I want so I AM NOT going to complain about it. I still think it is a great chip. But the people getting more than 100% overclocks on the 1700`s. Well they put the P4 1.6A to shame. AMD is again the overclockers king.
Well in melbourne gives you 2 options. I have read on an all Australian forum there is a certain computer shop in melbourne selling good T-Bred B`s. I think for memory the name was "Scoptec" or "ScorpionTech" one of those 2 names. You can just rock up there and have a look as they are getting fresh batches all te time. I do know for a fact they have sold out of B cores 4 or 5 times in the past 7 days. But they are always getting more stock in. Also another choice (What I did) is www.auspcmarket.com.au I got mine from there. They list T-Bred B 2100`s specificaly on their website but you can also ring them to get the exact stepping as well.
Hope this helps you on the way to overclockers blis.
As for unlocing on the T-Bred B`s it is very simple. You only have to connect a single L5 bridge right on the end of the whole line of briges. You dont even have to fill in the gap because you can just go around it. With a conductive silver marker pen it can be done in 10 seconds flat with 0 prep time. I am 100% serious on that.
