1660mhz
AMD AthlonXP 2000+ Bus Speed?
Can any one tell me what bus speed the AMD AthlonXP 2000+ cpu has?
I have PC2100 ram and want to know If I get PC2700 which is 166/333Mhz (I think), will it run at the speed or be downgraded to what the cpu bus speed is?
Regards.

on my old pc its stats are
Cpu speed: 1667mhz
FSB: 133mhz
multi: 12.5x
Cpu speed: 1667mhz
FSB: 133mhz
multi: 12.5x
Isnt that the actual cpu speed....or am i being stupid and the cpu speed and bus speed are the same things :S
12.5 x 133 is it a bearton core? the barton is 333 which will do 2700, the palomino is 266 which will slow down pc2700 to pc2100, download cpu-z and find out ya core.
cpu-z reports it as a Palomino
I have a 2000+ palomino core which i was never able to get above 2ghz stable, but you may have more luck.
The unlock is the old pencil trick but you have to do all the links, not just the first. I was only successfull in unlocking to every half, eg 10.5, 11.5, 12.5 etc.
Painfull but it got me an extra 15% I allways went back because it gets WAY hot even with a little overclock. These baby's need lots of ambient cooling, not just good cooling using a nice HSF.

You've got the same as me, so long as you have a good mobo it can be a fun overclocker, cos its easy to do (simple FSB etc).
give it lots of cooling, its old, cheap, go hard until its dead!!!!
PS i had pc2100 ram in it, and i often suspected that it was the bottleneck. You never know. I'd like to see how you go if you do get the pc2700.

Well im not looking to overclock really....just upgrade some parts of my pc.
For some reason it runs very slow, like windows explorer takes ages to load up....I have 2x 80gb hard drives of which are partitioned into 4x20gb, 2x20gb, 1x40gb. A lot of partitions as u can see, the drives list in explorer takes a while to display, I can even hear them start to spin up.
I'm looking to either upgrade the memory and/or harddrive, which are:
Maxtor 6Y080L0
Rotational Speed 7200 RPM
Interface Ultra-ATA/133
Buffer Size 2 MB
Seagate ST380020A
Rotational Speed 5400 RPM
Interface Ultra-ATA/100
Buffer Size 2 MB
The Seagate is my main bootable drive.

I just saw your PSU, a 300w? My first suggestion is to get something a little beefier!
you've got a few hard drives, which would draw a fair amount of power, and as i've said your cpu draws quite a lot as well.
Anyway, a new power supply is always good, MORE POWER!!!

Off topic, but if you bought a 160gig hard drive and transferred everything to it from your old 80's, you could raid them for increased speed (this is overclock.net after all), then have all the extra space aswell.
This would of course need the extra power supply i suggested before.

I've had this post on another forum.
Memory will (should) only degrade if you mix it, when it will run at the speed of the slowest stick. PC2700 is 333MHz. The CPU speed doesn't affect the memory speed, as they run on two different busses.
Any thoughts?

Can anybody please confirm if my cpu will slow down PC2700 to PC2100?
Your 2000+ is a palomino and it has 133 FSB (266 if you like it)
If you already have ddr2100 (wich coresponds to 133MHz) it runs synchron with the CPU, and on the Soket A this is very important. If you add another ddr2700 module (166Mhz) it will be slowed down to the speed of the slowest module you have, unless you decide to overclock the others to 166Mhz. All the memory modules on a mobo function at the same speed.
In soket A the best memory bandwith I had was when running the CPU and the ram at the same frequency, and I tried a lot of chipsets (nForce2, kt800, sis 735), so adding a ddr2700/166MHz module, even if it runs at this frequency won't help.
My advice is to buy more, since 256Mb is barely enough to run XP. A 512Mb would be the minimum to have some confort when you work/play.

Agree with drago.
The one benefit from running a higher speed rating ram on a low FSB system is the SPD tables. If you set the ram in bios to run according to SPD (some bios's use that exact term), it will run at tighter timings.
So for instance, PC3200 that runs 2.5-3-3-8 at 200 FSB could very well (depending on SPD table) run at 2-2-2-5 at 133 FSB.

You would be best served replacing the PC2100 RAM modules with say some 2 x 256Mb PC2700 modules at the minimum (2 x 512Mb even better) as your CPU is a PALOMINO core it is running with a fsb of 133MHz (266MHz effective)and PC2700 is 166MHz (remember DDR is double rate so 333MHz effective).
I think someone has stated that with the XP's running the CPU:MEMORY ratio at 1:1 with as tight timmings as you can is the best way to make the system perform.
It will just depend on what fsb you can get that core running at. Having the extra headroom on the RAM is not a bad thing but remember to run the RAM higher than the CPU fsb is quite pointless.
cheers
edit : dammn to old and too slow in the typing dept, you bet me too it ^^^^^^^
