AMD 2500 BARTON HELP!

Hey i have read many things about the 2500 bartons overclocking stablilty and have heard that it gets to as high as 2.2 ghz and staying stable compared to the 1.83 default clock. right now my amd 2500+ is in a leadtek nforce2 ultra 400 motherboard with a FSB of 200 under optimal setting within the bios. i have my fsb at 200 and my multiplers at 10 so im sitting at 2.0ghz and it runs idle at 51c and under load in CS:S jumps to about 59 then crash my source game and eventually resets it self. I have a thermal take heatsink and fan on it with artic paste for my thermal compound. my case fans are 2 titan 120mm fans with LOTS of Airflow one in thats on the back part of my case and two blowing out 1s my side case fan and one 120 in the front. Basically i think the processor may be a bit old and i would like to get 400 FSB. I just purchased a 6800 GT 256 made by XFX and a XFX Mach 4 motherboard.. I need some advice whether or not i should use my current motherboard and CPU combo or take my new motherboard and either buy a new heatsink and fan or buy a new CPU to get my 400 FSB if i can... im kind of a noobie but im learning 😀.. If you guys have question's on what im trying to say feel free to post or email me. I would really like to take some advice from you guys in this forum cause its quite a popular Forum.

Thanks,

I think you made a mistake when purchasing a "new" socket A mobo
the SLOWEST s754 setup will still outperform any socket A solution
if you can return the new board, I would do it.... and then get a s754 or s939 with a cheap cpu...... it will also match your video card better

but your problem is possibly due to voltage, your cpu may not be so good and need a little more juice to stay stable..... your temps arent great but should still be ok... feel your heatsink under load... does it actually feel hot?
 
First of all, amd spec'd the chip to run at 1.8 GHz. There might be a very good reason for that.
The temps you're seeing shouldn't kill the computer, but to me they sound too high for a chip sitting between two 120mm fans.
You may need to bump up the voltage slightly to go faster. Are you running DDR400 RAM? Ratio set to 1:1? Lots of things can effect system stability.
Overclock at your own risk.
 
Actually the reason i havent upgraded to 939 yet is budget issues. im only 16 making 200-300 tops on paychecks every two weeks and i have car insurance every month which is 136 bucks cause my brother effects mine cause he has been in like 3 accidents tottaling his cars and dont have much to spend on computer parts. The second reason i got this motherboard is because my orginal attentions for a upgrade was to only upgrade my video card from a radeon 9800 pro 128mb to a XFX 6800 GT 256mb AGP and the video card comes with a motherboard which i bought for 266 so its basically free in my point of view 😛 i would love the 90 nm idle 32c if i could but im on a budget like many gamers. i play CS:S and want to get the most out of my board and processor with out spending to much money. Basically the 120mm fans are keeping my system temp to 39c but now i clocked back to default and its running 49 idle.... i may need to get a new heatsink and cpu fan.. do you guys know if i can use a stock amd 64 3000+ heatsink and fan that comes from the manufacturer on my 462?
 
if you mean 462 i assume you are talking about the socket (i hear it called anything other than socket A so seldom) then the answer is no. The mounting systems are completely different. Are you running DDR 400 RAM? If you are are you running it at a 1:1 ratio. Also... you said you adjusted the multiplier. To the best of my knowledge, only the XP-Ms are unlocked so I assume you got that. (are the new 55W Bartons unlocked? I had heard a rumor but I haven't seen it corroborated as of yet) If your chip isn't unlocked then you really aren't doing anything to it anyway....

The default mulit on the 2500 Desktop is 11 and the default FSB is 166. If you bring the FSB up to 200 and bump the voltage to stabilize it you will be at 2.2 GHz.


On top of all of this is the fact that you have WAY to much graphics card for that system.... you could run that Barton at over 3 GHz and you would still be CPU limited in your games. But for $266 it is hard to pass up the deal... (no jealousy here... no sir)
 
the older barton cores were multiplier unlocked.... I assume you have one of those....

the possible solutions are therefore
1_ try upping the voltage
2_ make sure ram speed is not your limiting factor eg. too overclocked
3_ monitor your temps

if it was me... I would find some way to hock the cpu and the 2 boards that you have and get something s754/s939 .... sempron 2600/2800 in s754 with a nforce 3 mobo should be under 200.... if you can sell your 3 items for $130 or so, it would be worth it
 
Have been monitoring my temps alot lately so ill go ahead and try the FSB of 200 and bumping the voltage and see if it helps and yes my ratio is 1:1 for ram and i have 512 of Samsung pc-3200 2 sticks of 256 with pretty bad timings 😀 but hey VALUE SELECT ALL THE WAY! 😀 i have adjusted the timings to 2.5 4 4 6
 
So if i switch to a 754 mobo and get a sempron processor. is my CPU performance going to increase alot towards FPS and going to be able to keep up alot better with my 6800 GT? cause im defiently going to look into that if need be. if its under 200 then *SMILES* thats within my budget..
 
One more question on the Socet 754 subject here. if i got a amd 3200 64 for 754 would i be able to use a 64 3000 for 939 heatsink and fan? are the mounting brackets similiar? cause i have a friend that can give me on cause he just switched to watercooling so 😀 i can buy oem

edit:
another cpu option :::http://www2.newegg.com/Product/Product.asp?Item=N82E16819103491R ... there are other mobo options too, but I dont know how much you got to spend.... just look around

or http://www2.newegg.com/Product/Product.asp?Item=N82E16813123225

= system faster than yours 🙂
and yes the heatsink is the same as s939 systems ... but you wont be saving much by going oem..... actually not sure, im not familiar (not a us citizen 🙂

minus how much ever you can sell your stuff for and you wont have spent too much

this epox board should also be quite good for overclocking too.... some of the newegg buyers have reported 2.5ghz+
and if your're thinking why the sempron runs at a lower clock speed yet can be faster, its due to the newer generation architecture (on die memory controller)
you also have the option later on to upgrade to a faster/better s754 cpu..... not a bad pick

Hi Jordan and Welcome to the Forums!

I think there may be a little confusion here... There is no 400FSB CPU. Notwithstanding overclcoks, the fastest is 200FSB. The "400FSB" you see is 200 x 2 = 400, thats because the ram is DDR (Double data rate or something similar). So the 200FSB is multiplied by a factor of 2.

Intel systems brag of 800FSB, but again, this is mostly marketing hype. It's a 200FSB, multiplied by 4 because the ram is "quad pumped".

Regarding your multi: nForce mobo's will ALLOW you to change it in BIOS. But unless you have an old Barton (pre-week 39 of 02 or 03, I forget) it just defaults on it's own to 11. So it's likely you are at 2.2ghz with a FSB of 200.

Anyway, the important thing is here, that the 6800GT will run superb with a Barton 2500+ at stock speeds of 1.8ghz. I have proven this (at least to myself) with my rig. I have downclocked/underclocked my CPU to 2500+ and played games (graphics setings maxed) like Doom 3 and Far Cry and the 6800GT runs 'em like butter. I can only tell the difference in benchies.

I have a AXP 2500+ Barton as well. I got one of the original non-mobile ones, so it actually is multiplier unlocked.

Anyway, what I've noticed is that mine's extremely unstable at 200MHz x 10. I can run it at 200MHz x 11, and it's perfectly stable, but at 200x10 it won't even POST most of the time.
As far as your reported temps -- it's not usually a good idea to take you motherboard reported temps as accurate. They vary between boards, even between BIOS revisions of the same board. Feel your HSF - is it warm? It should be, if it's not that might be a good indication that it's not conducting heat very well. It could also be that it's sitting between two 120mm fans. 😛

Other than that, I can't help you. I've never figured out why mine behaves the way it does at 200x10 either.
 
Thanks for the help guys i appreciate it. but i have took in to great consideration about getting a 754pin and selling my two Socket A motherboards im not exactly sure what motherboard im probably gonna get but im thinking about a 64 3200+ or 3000+ for the processor and putting my 6800 GT in it.. do you guys think i will gain that much more for the upgrade?
 
I know its extremely hard to do, but save up your money for a s939 CPU! I saved up about $1000 in 4 weeks and built a killer S939 3200+ based system. It blows my old XP 2500+ away! You won't be happy with a S754 system. It's only single channel and it's not as upgradable. I think your system it restarting because you're pushing that barton to far. Not all chips overclock the same.

I assume you have an nForce2 boards. A lot of BIOSes for these boards have trouble with the "terrible tens". Multipliers of 10 and 10.5 often won't POST but 11 up are fine. My four A7N8X boards with the latest ASUS BIOS wouldn't POST with these multipliers when a mobile XP was installed. When I went to the Trats modded BIOS, this problem was fixed. So you might want to look around for a new BIOS if you need these multis.
