Help me OC my XP2500+

[imported_speedy]

I´v been trying to OC my XP2500+ for a while but I´v only reached about 2Ghz(and not very stable)... Most people seem to be able to get theirs to run @ XP3200+ so Im not very satisfied with my results.

I have tryed to raise the voltage to the cpu and memory but the only thing that does is make the temperature go up.

The temperature is currently at 48Celcius idle and was att like 55 when overclocked.

The setup:
Motherboard: Epox RDA+ rev1.1 (Is the old rev. a problem?)

Memory: 2x512MB TwinMos PC3200 (should be alble to run at 200Mhz FSB atleast?)

Processor: AMD XP2500+ (AQXEA 0330SPMW, a preatty good stepping, isnt it?)

Cooling: Glacialtech silentbreeze, with a 80mm Enermax fan(http://www.glacialtech.com/pop-productsb3.htm)

I´v thought about getting a new cpu cooler but Im a bit unsure if this would help much. What do u recomend?

You have to increase your voltage and it is going to get hot, so you have to keep it cool. 55C will not kill your system; if you go to AMD's site you should be able to see the specs for your processor. I would prefer to be under 60C.

Going back to the voltage part, I don't have the same board you have; I have an Abit NF v2. I have to set my voltage at 7.5 if I want to run my 2500 at 2.2 GHz. There are other factors that play an important roll in the game like memory, power supply, temps...etc.

I would set everything to default and start increasing fsb and volt. little by little and see how high you could go. Run prime95 to make sure you are stable, keep an eye on your temps. Also, try different memory settings, try one stick to see if that helps, try different slots.

Good luck

55C at idle is way too damn hot. If that is accurate you are probably around 70-75C load. If you are going to be increasing vcore any I strongly advise you buy better cooling.

My guess is that it's a 2x512 problem. .

 

[imported_speedy]

The problem is... i dont want to get some expencive cooling if its not gonna help much :/

Just as Lithan said, I also suspect the memory .. but shouldent it at least go upp to 200Mhz FSB? Thats whats its specced for.

Im gonna upgrade to a A64 system within the next 6 months or so. Is it posible to get a cooler that would also fit my future socket 939? Then I wouldent have such a problem with spending that money

Your motherboard northbridge may not be able to run 200MHz stable. The first revisions of the 8RDA's only went to about 185MHz. Lower the fsb and use a higher multiplier.

I was about to post in the forum my results so far ocing my little 2500+ Barton.

55 degrees is way too hot man. That 2500 barton can handle 200 mhz fsb no problem, with hardly any extra heat. you just have to have the right cooling in the first place. At first I was a skeptic, then I thought I'd try it, but now I'm a believer: 120 MM fans. two of em. one in the front blowing in, one in the back blowing out. That plus a decent aftermarket heatsink and you've got some good cooling for the Barton. I just RMAd that trashy no good case made by thermaltake, the xaserV. It had 5 80 mm fans at least, and turned up all the way it sounded like a damn hairdryer. It could not keep my temp below 50 degrees. This antec does it and it doesn't make a peep. You might could put another fan in yours.

I don't know if your processor is locked, or if your MB is having a problem, the first thing I'm seeing with yours is the heat. Mine sits at 45. It was 43 before I OCed it.

I'm not sure what to tell you. The heat for one, one 80 mm doesn't cut it :/. Maybe add another 80 on the front. I'd have to look at your motherboard and see what is possible. MyMSI Nvidia makes ocing pretty simple. Keep posting ideas, I'll look in and maybe I'll find something new.

Hey treadhed, did you do any benchmark on your system? We have similiar system specs and but I didnt OC my cpu. Im just wondering what would happen if i did.

Thanks

I don't think it's locked. It looks to be from week 30, 2003. They didn't start locking them till week 39-41.

 

[masshass81]

If it makes you feel better, I can't hit 2.2ghz with my barton 2600+ :brokenheart: Can't get it past 2.173 w/ 1.775 vcore (imo, too high!), but thats with stock hsf.. Hopefull I can get past that with a better HSF and at a lower voltage..

 

[imported_speedy]

Im gonna try to get better cooling but Im afraid that its also my mobo thats causing trouble

 

[Delorian]

My suggestion would be to cool your NB chipset if your CPU is locked. It may seem a bit crazy, but I think your NB can't handle the load as it's only gauranteed rated at 166FSB. Your ram is rated higher, every 2500+ can handle at least 2.0 GHz and 175 FSB.

As Rogue1979 stated (if your cpu is unlocked of course), attempt to lower your multiplier and raise your FSB. This will tell you wether or not your mobo can handle the heat/speeds. If you can hit 200FSB on your Mobo with your cpu multiplier really low, then it shouldn't be the problem. Next try to stay at 166FSB (or around there) and raise your multiplier, if it hits maximum, you should start bumping up the fsb until it hits an unstable point or until your temps are too high. Your RAM shouldn't be a problem as it's rated up to 200.

Even if it's locked you can still run it at 2.2ghz easy. You just can't change the multipliers. Just increase the fsb and vcore and it will easily go to 2.2 and above, my locked 2500 will

My locked 2500 does as well. Only raise the VCore if necessary though...

 

[McMadman]

My 2500+ (week 44 I believe) is locked and using the stock cooling can NOT reach 2.2ghz stable.
1.8v resulted in ~63c temps and prime95 was still unstable.

190fsb (2090mhz) is rock solid at stock voltage and about 51-57c depending on ambient temp.

edit:
Rather than bump the thread for my response to Delorian, I'll just edit.

Unless the excess heat is the problem, then I just don't think my 2500 can make it, it goes from rock solid at 190 1.65v to unstable at 200 any voltages (I didn't try any of the extremes above 1.8)

I was planning on purchasing a zalman 7000 (or a speeze falconrock if the zalman can't fit) but that has been temporarily delayed.

 

[Delorian]

mcmadman - put a better HSF on it and raise the vcore to 1.7 or 1.75 and you'll be 200 fsb or more easily

Yeah, yours is quite similar to mine. Actually, that message was in err. I have a strange problem that when running 3d applications my video processor locks up. As a matter of fact, I discovered this when running 3dmark2001se. It also locks up when I'm playing Doom3. I imagine it will do so when I run any 3d application. Under factory settings it performs fine.

I am going to try monkeying around with my memory settings, I have a feeling that it just may be the video processor is getting corrupt data and does not know what to do with it. The CPU performs great, it is just something in between that is causing the problem I will keep you updated. Anyone reading this thread that may have some ideas, feel free to post.

You might try to underclock your GPU/Video mem as well as these may be overheating. It's not common but does happen even when you aren't OCing the card. Doom3 has shown many cards at stock settings can overheat when pushed hard enough. Also heat from your OCed CPU may be warming up your case/card and affecting your vid card this way too.

I have been a bit busy at work so I havent had time for this in a while

Anyways... now I have bought a Zalman CNPS7000B-Cu.. wohoo! My cpu is at 38-40C idle an just a couple of degrees higher in full load.

I tryed to OC the cpu last weekend but had a lot of trouble with bluescreens. I got to about 2Ghz without any stability- or heatproblems in windows. It was just in games I had problems. It said something about nv4_disp getting in to an infinite loop... Is this a common problem? Is there a solution?

Instability is a huge problem for me and I´d rather have a comp that is a bit slower than a one that can crash at any moment.

 

[Xecuter]

all i can say is that im running a barton 2500+ at 2.2 ghz perfectly with an a7n8x deluxe motherboard and corsair xms pc2700. i got 4 case fans in here, and an alpha 8045 heatsink with a case fan on it, so = 5 case fans
maybe my setup can help (???) the a7n8x deluxe overclocks very nicely. all i did was increase the fsb to 200mhz, and not the clock multiplier.
hope this may help.
oc'ed temps = 41 C idle, around 51 playing doom 3 (full load)
try increasing the voltage of the fans to 12v instead of 5v. may be louder, but gets rid of the heat.

[LoudTIGER]

i had an athlonxp barton 2500+ running at 10.5x210, rock stable, but i have to up the volts to 1.8v. the hottest it got was around 53-55C. this was on a Abit NF7 rev2 and alpha 8045 with vantec tornado 80mm fan. maybe you should try improving your cooling? i'm also not familiar with your motherboard, so maybe that is the culprit?

Did you try raising the voltage a bit or lowering the fsb and using a higher multiplier like was recommended above?

 

[wampa]

Another thing that can be hindering your Overclocking could be your power supply. What brand is your power supply? You can try loosening your memory timings, to something really slow like 3-5-5-13. Just to make sure that your memory is not the culprit.

 

[Cdubneeddeal]

Don't mean to threadjack but I wanted to post my oc results with an NF7-S v2.0 and a locked barton 2500.

I have it up to 2.4 ghz 440mhz fsb with two sticks of PQI Turbo (512x2) 2.5 3 3 8. On air mind you.

If you have decent ram try raising the fsb and increase the vcore to around 1.725. I didn't read the whole post but by skimming through some of the posts heat was an issue. If you have around $30 or so to spend invest in a Thermalright SLK800u or above and get some AS5 and a good high speed fan that'll push a lot of cfm. Make sure you have adequate cooling inside your case as well. And by all means, cool the southbridge and your mosfets. wluk has some nice size heatsinks for both fairly cheap.

 

[imported_speedy]

I dont think the cooling needs to be improved... 40c is pretty cool.

I tryed raising the voltage a bit. I got to 1,75 without seeing any aprovement in stability.

It seems that its only in 3d grafics that the instability appers.

The PSU is a 350W Antec smartpower.
