OK, I will read up on it but I am having a hard time finding a google response that gives me a basic tutorial on OC. First, can I OC this set-up and which memory should I use?
I have a Tyan Thunder i7505
Dual Xeon 4, 3.06Ghz CPU's that rate at 3060MHz / 4 x 133, multiplier 23/1x
Supports 128MB, 256MB, 512MB and 1GB unbuffered DDR200/266 modules' memory.
I have two 1024 2100's (133MHz)
I have (not installed) two 1024 2700's (333MHz)
Lot's more, it is a pretty beafy PC that I use as my workstation. I have 6 rackmount servers also and want to learn how to OC so I can tweak any one of them but I do not know what I am doing. I put the the system specs on web if any one wants to see in order to give me advice or not at http://www.uberfly.net/TyanUserManual.pdf
Any Help is appreciated
If it ain't broke then mess with it until it is

Thanks for the advice. I think the problem might be that my CPU is locked. It's an AMD 3000+ XP, and I bought it a few months ago. I've been searching around and it seems that the consensus is that newer AMD CPU's are locked.
On the FSB front, 200Mhx is the max my mobo will recognize, so I can't seem to kick it up any higher. I'm not sure I have any options left, other than to overclock the graphics card...

Smather sorry to ignore you there mate. I really don't know about dual cpu boards other than they are not aimed at the enthusiast market. So even though I haven't researched your board I would say that the options to overclock would be vey limited if at all. If your board will support the pc2700 memory I would install it. If you want to overclock build a cheaper system with older components and light er up with no worries.

Askyew - thanks a ton for your help. Those links were very helpful. One of the links you sent had a screenshot of the possible FSB settings, and the menu looked much different than what I had seen. So I knew if I played around in the BIOS enough, I'd get there.
Turns out my mobo can go up to 300 mhz, if you know how to use it. My problem wasn't a matter of setting the right jumper cables, it was just a BIOS setting issue. I blame partly myself and partly the poor instruction manual (which made no mention of FSB settings higher than 200mhz!).
Thanks again.

BurlIves, I am confused:
I belive the XP3200+ is the only Athlon that runs 200/400FSB.
Your XP3000+ runs 166FSB, does it not?
There is no XP3000+ chip available that runs 10.5 x 200 = 2100MHz (not in Canada, at least).
A stock XP3000+ Barton runs 13 x 166 = 2167MHz.
My XP2500+ Barton runs 11 x 166 = 1833MHz.
When switched to 200FSB, it comes up XP3200+ as I, Praetor, agent-k, and countless others know very well :)
Can you confirm your info using CPU-Z?

It's definitely 200/400 FSB. Here's a link to where I bought it from (newegg) where they list some of the specs:
http://www.newegg.com/app/ViewProductDesc.asp?description=19-103-394&depa=0
When I get home tonight, I'll send you a link to this definitive writeup someone did that explains all the differences between the AMD chips. That also shows the XP3000 is 200 FSB.
On another note, now that I know how to kick up the FSB past 200 on my mobo, it's slow going. So far, I'm stable at 210, but not 220. Going to have to really starting picking through this thread to see the kinds of things I can do to increase stability...

There you go: so it is.
Never seen one before - my wholesaler doesn't list it!
To increase stability, run it @ 200 :)
To weasle a bit more performance, and throw off your PCI and AGP timing, OC.
That (and the fullspeed L2) is why you can reach 210 but not 220MHz...
At 220 your AGP will run 73.333 instead of 66.
Also PC3500 memory would help, but your PC3200 will probably OC, if left to its SPD settings.
Have you increased CPU voltage beyond 1.65v?
If you are stable @ 210/420DDR, be happy I guess.
(Hey, 200 is a wicked OC for us!)

I'm surprised to hear you so complacent on my results. You are the OC gods, right? The way I figure it, you guys are able to kick up FSBs from 166 to 200 (20% increase), so why can't I? That would mean 240 FSB. But I have to settle for 210 (5% increase). You gotta understand, I want to see that gore SPARKLE in doom 3!
So I'll press forward on tweaking a bit further. I tried kicking up CPU voltage from 1.65 to 1.7, but I couldn't post (so picky!). Tried shortening the memory timings as well, but to the same effect.
I've left the memory speed at its SPD settings which I assume means the BIOS will keep it synched to the CPU speed, so I don't think I can improve there. But I wonder if the memory is just more sensitive to the O/C than the CPU. Combine that with the fact that my CPU is locked on the multiplier (so my only O/C option is to increase FSB) and that explains why I can't get the same overall speed (FSB * multiplier) increase as you guys, when measured on a % increase basis.

BurlIves, when you say you tried to shorten the mem timings did you lower them? To relax the mem timings you need higher numbers to help with the overclock. My pc3200 will do 230fsb at spd (which means the mems rated timings) 3-3-3-8 but over that I have to relax the timings to 3-4-4-8. Have you tried to raise the mems voltage? The mem voltage is a great tool in getting stable overclocks but I personally relax the timings first. After you achieve the overclock even if you boot into windows you still may have instability issues. I always run mem test to check the memory after a succesful overclock, if it fails I relax the timings. If it fails after relaxing the timings, then I raise the mem voltage .5v at a time until I get no errors. Then stess test with looping sis sandra and watch the temps. Always watch the temps closely when overclocking and if you don't have heat spreaders on your ram then get some. Here is a good place to get bench/stability tools:

Smather are you an intel or amd kinda guy? What type of overclocks are you looking for? How much money ya got? I love my IC7 but it is getting dated and kind of pricey still at 134usd at newegg. It has gone as far as 270mhz fsb with the ram at 5/4 but it wasn't prime stable(with the vcore @ stock voltage) and the heat kinda scared me. There are alot of people that have gotten it stable at 300fsb with water cooling. I am currently running 230fsb 24/7 stock air cooling with good case ventilation. There is also the 865 springdale intel chipset bords that go for under 100usd that are the sister of the 875 canterwood boards. The latest northwood processor is the MO stepping which is supposed to give great overclocks but my old D1 does just fine. The P4 2.8C runs about 180usd at newegg but the big overclocking 2.4c runs about 145usd. I recommend the northwood "C" core because it has less heat issues than the prescott "E" core. If you are into amd you can find the older mobile xp processors to be a real bargain shown here:
http://www.newegg.com/app/ViewProduct.asp?submit=property&DEPA=1
Be sure and check out the reviews to see what boards other people are using with it.The reason I like the mobile is that the lower wattage allows more overclock with less heat= more stability. Plus they are socketA so budget boards are common. I know that the mobile will work with the Abit nf7-s boards but the dividers are kind of hit or miss, or so I have read, but it could be user error(The intel 865/875 has good agp/pci locks until around 300mhz fsb). Just remember that if you go budget with these boards that they are very old and dated but they are cheap. If you have a manufacturer in mind then go here and reaserch the boards with socketA/462 processors:
http://www.hardocp.com/reviews.html?cat=MiwsLCws
The Hardocp sight is how I decided on my board and they were right on.

Thanks for the suggestions, askyew. I kicked the FSB to 220, increased the memory timings to 3-4-4-9, and kicked up the mem voltage from 1.6 to 1.7, but I've still got stability problems in windows.
I went to that website you referenced and downloaded some monitoring programs (thanks for the link), so maybe that will help.

BurlIves I kind of stopped short on the stability steps that I use, must be gettin old and not as sharp. I use the burn in in sis sandra looping at least 30 times because usually it will help with the new overclock stability and maybe help to higher overclocks. After a good burn in I use prime to test the stability. Let prime run for at least 24hrs and look for errors.

That's some great info askyew :)
@ BurlIves, lemme just point out that 200FSB is top of the line for AMD (and Intel) right now, so you cannot just switch up to the next 'factory' OC level, complete with proper dividers, like I and others have done.
You are doin' it the traditional way, uncharted territory etc.
Therefore, 20% is huge - that's not just 40MHz more FSB, it's also AGP @ 80MHz instead of 66, and PCI @ 40MHz, y'know? You will be lucky to make that run.
Also, memory timings by SPD and CPU:Memory ratio are two different things.
Once you hit 200FSB your ratio will be locked at 1:1 (or 6:6, same thing) identical to CPU.
However, you can still tinker with internal memory timings, which are more like wait states.
Big $$ memory has less wait states, and will offer it proudly, right up front in the SPD that describes the memory's capability.
I still say relax, your system is sweet :)
10% is heavy duty OC, very manly PC.
You (and I) need Athlon64 on Socket939, or what?

I'm new to overclocking and wanted to get a AMD XP Mobile 2500+ or a 2600+ before they get replaced with Semprons or get a AMD XP Barton 3000+ 333 mhz and needed help deciding from people who have some experience with this...
Currently, I have a Soyo KT400 but if needed I will spend an extra $40-50 on a NForce 2 or something of that sort.
Question # 1
Using a Soyo KT400 Ultra (Not Platinum) and Cooling: 5 case fans (1x120 mm and 4x90mm), CoolerMaster Aero 7 Lite (CP5-8J71F), how much can I overclock the Mobile 2500+?
Question # 2
I am looking for stability, so does it make sense to buy a AMD XP Barton 3000+ 333 mhz instead of overclocking? and if i overclock this processor how far will it go using 5 case fans (1x120 mm and 4x90mm), CoolerMaster Aero 7 Lite (CP5-8J71F)?
Question # 3
Since the 2500+ runs at 266 mhz stock, is it possible to get it to run at 400 mhz since my memory is 512 MB DDR PC3200 400 mhz?
Question # 4
If if get a NForce 2 board, and then overclock using these processors, how will it compare to the kt400?
Please let me know!
Thanks...

The Semprons are surprisingly good. I've fitted a few Sempron 2400's and they are very fast for a Duron replacement. And they overclock to a sempron 2800 with nothing but an FSB increase.
The XP2500 runs at 333Mhz stock.
And they are difficult to get now as well.

SmatherI am sure that agent-k will be helpful in recommending a good overclocking amd solution. As far as the Intel goes I love my Abit IC7-G with the 2.8c intel together about $315usd. I have had the board and processor@275mhz fsb at stock vcore voltage on the 2.8 for a speed of 3.85ghz and a bus speed of 1100mhz. The ram I have is kingston valuram PC3200 ddr which specs at 3-3-3-8@400mhz/2.6v. I does 2.5-3-3-8@400mhz/2.6v,3-3-3-8@460mhz(230fsb)/2.6v,3-4-4-8@500mhz(250fsb)/2.7v for $100usd I got 512mb(2x256) and it is running dual channel. There is much better ram out there but you better get ready to pay for it. I wish that I would have bought the ati 9600xt video card cause mine has no cooling solution and it makes overclocking scary. I also had to download a soft mod to be able to overclock my card. They can be had for about $170usd and it is a much higher performance card than the plain 9600, plus the xt monitors the core temps and comes with overclocking software. I bought an antec sonata case, it is quite but I had to mod it to get more fans in it for air flow. I bought it from the antec site without a power supply for about $80usd. I bought the true power 430 from newegg about $60. Newegg sells the sonata with the 380 true power for about $100+15(ship) but I spent 25 to get the bigger power supply. Speaking of which, This is very important, do not get a cheap power supply. It is one of the most important things in your system. It can be the cause of random reboots and other quirks so dont skimp on it. It can even be the cause of destroyed components. Here is the next thing that I intend to buy for my system it offers excellent cooling without tornado like noise and its weight falls within the intel specs. The added bonus is that I don't have to remove anything and use screws. It mounts in the intel hs/fan bracket with no modification:
http://www.quietpcusa.com/acb/showdetl.cfm?&DID=8&Product_ID=55&CATID=3
There is also an all copper one but it weighs much more. There are also alot of fan cooled heatpipe heatsinks out there. I believe that thermalright may be the best solution right now with the sp-94 and the xp-120. Beware they are big and heavy check to make sure they are compatable with the mother board you are buying. Take a look here:

@amdxpm
Apparently the mobile 2500+ has multipliers unlocked.
This is useful because, normally 166FSB would be serious OC for this CPU, however 200FSB could be achieved by actually reducing the multiplier.
All things being equal, xMHz on 200FSB will outperform xMHz on 166FSB, y'know?
XP3000+ Bartons are not to be expected to run 200FSB
(that is why the 2500+ Barton is such a treasure - it has the minimum multiplier of the 166FSB Barton range :)

Exactly the-OGS, the Athalon64's are supposed to allow you to reduce the multiplier allowing for more fsb headroom. They seem to be an excellent choice but they have left the amd trend of being the "more bang for your buck" because of signifigant price increases. That is why I am so impressed by the mobile xp it offers more overclockability while still being an affordable solution.

The 6ghz barrier was broken with a prescott 775 socket. So yes they are pretty good overclockers, but it was done using liquid nitrogen cooling. The prescott does run a little hot but I am seeing less complaints with the new sockets. Most of the socket 478 boards weren't built for the prescott's power hungry core(bios updates made them compatible). The new lga775 boards are designed for the prescott so probably are a better solution. Plus the asus boards have unlocked the pressy cores 3.2 and above on both sockets with their new premium boards and bios's. They will allow you to lower the multiplier to as low as 14x and give a better fsb overclock for that high speed ram. The 60c is probably a number that the prescott is comfortable with the question is are you?

Well I won't be getting liquid nitrogen cooling or watercooling. So what kind of mhz increase can I realistically expect to get using good air cooling? (ps this is the socket 775 ed. And I may well get a vapochill case in the future when socket 775 become cheap and available second hand.)

I would guesss that if you get a decent mobo and an aftermarket cooler, at least 500mhz is realistic but your results may vary. I can get 420mhz 24/7 with the northwood core and stock intel heatsink/fan.
