I just got this one yesterday with the abit NF7-s.

Using the stock amd heatsink right now. At 200fsb it won't even post.
From what I heard hitting 200 was pretty much guaranteed with the 2500.
Stable up to about 190. My ram isn't the problem. Ran that at 200 for awhile just fine.
Tried bumping the volt to 2.8. Didn't really help. Got past post once. Just ordered a better cpufan. Hopefully that will help. But I should at least be able to get into windows for awhile before heat becomes an issue. Right?
Suggestions? Help? Please!

Are you using stock cooling? Heat would not be the reason you aren't posting unless you hosed the install. Do you mean 1.8? Surely you aren't using 2.8.

Depends what NF7-S you have. versions 1.0 and 1.1 have that problem. Version 2 does not.

Take the side off of the case and blow a big fan at the cpu. If that does the trick, then you simply need to keep the cpu cooler. Keep in mind that the best cooler won't solve the problem if you don't have a breeze moving across it. The cpu will probably need at least 1.75v to run at 2200.

Yeah I meant 1.8.
I haven't put the cover on the case yet. It is a revision 2.0.
Has anyone heard of anyone getting a 2500 that didn't hit 3200?

with a 2dollar svc gr68 (or whatever model # it is) I ran fine @ 3200+ I have a fan in the front bezel blowing in and one blowing out the top back of the case also.

you dont need 1.75 volts to run a 3200, what are you talking about? i run mine stock voltage... Is your multiplier locked? the new 2500's are locked.. if not then you can try and just compensate for the FSB

not all 2500+'s can hit 2200 on stock. mine did but wasn't very stable when i did divx or large wav encodes.

1.7vcore and i can run prime95 for 24+hours solid.

I jut got one and I started at 1.7v and it posted just fine at 200fsb with 1:1 ram timings....I then backed it down to where it is now 1.65v bios and 1.65v actual...decent board for this!!! DFI ULtra NF2....

I wish I could use the multiplier and take it up that way since my cas 2.5 ram just can't take much past 200fsb...I did briefly test 2300mhz or 209fsb and it ran fine for 4 hours prime before I stopped it...Temps never crossed 50c...

I am using stock HSF but must have gptten lucky as my heatsink is the one with the copper block bolted onto the bottom of the heatsink....

I think some of us around here at to blame for threads like this one. Adam, despite what you read not all the 2500+ chips are going to do 200MHz FSB, at least not at the default multiplier and voltages. I was able to pop my chip in, bolt on my Alpha, and fire the system up right out of the box at 11 x 200MHz @ default Vcore. This is a best case scenario and I was lucky.

You might have to do several things to get 200MHz FSB:

1. Drop the multiplier to say 10 and see if it POSTs there.
2. Up your Chipset voltage in Softmenu. Try one of the higher settings.
3. Up your RAM voltage. Perhaps your RAM is crapping out.
4. What PSU are you using? Perhaps it's got rail problems?

Hopefully one of those ideas will help.

Yep, mine won't do 3200 without 1.85V (which is too high in my opinion) to be Prime95 stable. Others in this forum have also failed with the 2500->3200 overclock.

I believe most can do 3200+, but many of them can't do it at stock voltage and many can't pass Prime95.

Anyways, a better HSF would help. But I wouldn't be suprised if you got it to 3200+ and it wasn't able to pass a Prime95 torture test.

hmm. i have a week 43 locked barton 2500.

i have my FSB @210. that means the cpu is at 2.31Ghz. 1.65volts (1.67-1.68 actual)

some of you guys have been saying that 2.3 ghz is for lucky people. so am i lucky?
i'm totally prime stable, and actually i can take the FSB to 215 to be stable, but then i have to raise voltage to 1.75. it starts to run really hot at that point because i have my zalman HSF running at 1600rpms.

i don't wanna raise the rpms on the hsf. it's silent the way it is, and i like silent.

my question is.... IS IT WORTH IT TO UNLOCK THE MULTIPLIER? i saw the other thread that now allows for week 43s to be unlocked. anyway, if i unlocked it, do you think i could go much higher?

sugarkang, I think you will be facing the law of diminishing returns the higher you go. 2.3GHz is pretty damn high as it is, especially at the low Vcore you have.

What Voltage is too high for the Barton 2500+? Mine is currently at 1.72 (according to CPU-Z) and this seems to be default as I haven't yet increased the voltage or FSB. When I did attempt to increase FSB from 166 to 200Mhz, the system gave a blue screen of death after it began to load Win XP. It posted fine, but my initial thought was that I never adjusted the Voltage. Should I raise the Voltage by 5% and take the FSB to 200Mhz? Current CPU temp is 49 deg C.

I "butted" in because it sounds like the solution to my problem may very well be the solution to AdamBrouillard's problem as well.

Thanks.

I recently bought a new ram...

tried to clock it to 200mzh...worked...

then a new case came...

moved...

new heatsink came...moved...

tried again...FAILED

200 FAILED....166...FAILED...133 FAILDED...100 works...but the speed isn't doing it for me. The problem is that my CPU's Core is chipped because from replacing the heatsink i chipped the CPU and now it won't run higher then 100MZH FBS.

Happy new years everyone...

I'm tryin to contact AMD for a replacement.

That's like a horror story!

Hope AMD pulls through for ya...

Were you using an Athlon XP 2500+? It sounds like you had it working like a champ (unlike AdamBrouillard and myself)...

yup...i was using a 2500+

now it works as if the cpu's a 1100+...cuz of the "chip" on the core.

Boxed, unless you were using the stock heatsink and a thermal pad every time, AMD is very unlikely to give you a replacement, especially considering you were overclocking.

totally wrong.....

it's the v1.0, 1.1, and 1.2s are "far superior" to the stinky arse v2.0s.... v2.0s suck..... euck.

I take many older gen nforce2 boards and beat the CRAP out of v2.0 boards in intensive non-stop game stability at high FSBs. v2.0s are what you would wanna avoid... besides.. it's hard to get v1.0, 1.1, or 1.2s these days so yur fooked..

to the first poster, it's not the ram nor ANYTHING else is holding you back... what's holding you back is yur stinky arse v2.0 board.. that's the one screwing up everything. Ditch that board please...

there are no barton2500+ that can't hit 200FSB even with a default multi of 11x. it's not some... it's all of these chips will do 200fsb fine but it's the board that is screwing him up..
