Ok guys. I switched my 2500 Barton over to my Asus A7n8X dlx.
I have the latest and great Bios (1006) for my board.
So, what can I expect out of this chip?
AXDA2500DK4D
Y829958260194
AQXDA0315TPAW
it's on air, and currently running at stock speed.
A lot of guys running these at 200 fsb or better, and staying below 1.85V.
If you cooling and memory are willing.....
I can't wait to see your results.
You are pretty lucky and got a "Y" stepping with a pretty low batchnumber. I´m pretty sure that cpu does 2.5 at max voltage on that board on medium to good air. What is max vcore on that board btw?
Any 2500 "Y" at or below week 30 is a gem. Week 30 is the best ones though.
I got 1 of: AXDA2500DKV4D Y864897240216
AQXEA 0330VPMW and 1 with 0213 that both does 2.7 on a vapo and well over 2.5 on a bad water setup so far.

I got this one right after the Bartons came on the market.
On this board the Vcore goes up to 1.850
The clock goes up to 300 mhz (that's scary).. lol
Multiplier goes to 14.
What multiplier are you guys running your Barton's at?
Mine's at 11 right now.
I heard lower is better.
Ram is one stick of
KINGSTON HyperX 512MB DDR333 (PC2700) 64X64 DDR RAM
I have 2 sticks and had the V1 board running in dual mode, but after I RMA'ed the V1, I used the second stick for another mobo.
It's my understanding that anything over 512 is overkill, anyhow.

Depends on how good memory you have really. Let say you know that a cpu does 2.5 max stable and you have memory that does 200 Fsb at tight timings, 12,5 on the multi would be the obvious choice off course. If your memory and board did 250Fsb stable, the natural choice would be 10. Higher memory bandwidth is much better than raw cpu power, but on Folding, it doesnt matter.
BDR said Ram is one stick of

To test things, set the memory voltage to the max what the board allows you to. (I guess 2.8) and go up on the fsb to 190.
Use divider 1:1 for true speed (called sync). Just use a low multiplier like 8 or 8,5 so that you know that the cpu isnt the limit when you test your memory. Then go up 2 fsb at a time until it gives you instability. Drop 2 fsb and you have the limit. Dont be afraid to use the voltage the board has. I have never seen any system going down due to the use of full onboard volts on chipset, ram and cpu voltage. (SOME boards allows up to over 2.2V on cpu which i STRONGLY recommending not to use)
Let us know and we get you there in a overclocking fasion.
I ran the mem voltage up to 2.8. It seems to have a little lag in opening programs, or is it just that the latest version of CPU Z is just buggy?
I'll have to check mem timings. I reset them to auto when I reset CMOS.
I'm presently at 213 X 11 with my Barton 2500 and 1.8v vcore and I believe I still have some headroom left on this proc. I'm still working it up to see how high this proc can go, since I have a good psu in this rig now.
BTW, what rev. A7N8X dlx do you have, BDR? The reason I ask is that if it is an early rev, like the 1.04 I have, then you will have hell getting past 190 fsb or so without modding due to the early rev of the northbridge chipset.
This is a version2, but not sure what revision.
Where abouts on the mobo is the revision Number for this board?
This was a replacement board for an RMA'ed V1, 1.3 (I think).
I'm taking one thing at a time on the OC'ing. That way if it fails, I know what failed.
That means it´s using the 5:4 divider by default. 196/5X4 is 159-161 depending if your board is overclocking slightly which most do by default. Drop to 161 but use 100% or whatever it´s called for true memory bandwidth.
after you get better cooling why don't you see if you can run 14X166 first then up the fsb. Best way to oc is to find the max mhz then work on the multi X fsb that is best performance and still stable.
Yesterday morning I woke up to this tower being froze up with only the background on screen and no icons or taskbar showing.
I powered it off, rebooted (the boot up was slow), and it loaded slowly an ran like molasses.
I rebooted, reset to stock in bios, and so far it seems to be running ok. Back up to speed.
I'm going to leave this at stock until I get a better hsf.
At least it's folding wu's and not locked up.
I'm having similar problems, BDR, on my 2500+... even at 1.75V, I can't run for more than 12 hours at 11x200, the system just freezes. Runs about 45C at that voltage, too... anybody venture a guess as to what I'm doing wrong? I've got an SLK-800 with 53 CFM running through it on there... I've gotta get this thing running stable by tomorrow!

I dunno, Thrax, the reviews I've seen place the DFI up there in the top 3 OC'ers... I haven't seen a review that failed with an overclock up to 400FSB...
But then again, it might be that damn DFI board...

I reset CMOS, and starting over.
Yes, Sorry about that. They call it different in different boards.
Memory @ 100% it should be.
I'm at 182@11x, on default mem voltage right now.
Not bad at all. Give her some more! What timings are you using?
Cas 2?
I'll have to check mem timings. I reset them to auto when I reset CMOS.
BTW, what rev. A7N8X dlx do you have, BDR? The reason I ask is that if it is an early rev, like the 1.04 I have, then you will have hell getting past 190 fsb or so without modding due to the early rev of the northbridge chipset.

I'm taking one thing at a time on the OC'ing. That way if it fails, I know what failed.
I'm at 194@11X right now. I left memory freq on auto and it's at 161. Seems to be working ok.
Drop the multi to 10 and go up on the fsb.
Ahh...its at auto and you have it at 196?
That means it´s using the 5:4 divider by default. 196/5X4 is 159-161 depending if your board is overclocking slightly which most do by default. Drop to 161 but use 100% or whatever it´s called for true memory bandwidth.
This is a Folder, so it needs to run stable too.
That looks like a good stepping you got there.
What voltage is it at? You should get better cooling. These chips are awesome.
I'm looking for better cooling, then I'll try again.
I powered it off, rebooted (the boot up was slow), and it loaded slowly an ran like molasses.
I rebooted, reset to stock in bios, and so far it seems to be running ok. Back up to speed.
I'm going to leave this at stock until I get a better hsf.
At least it's folding wu's and not locked up.
It's that damn DFI board!
But then again, it might be that damn DFI board...
otherwise do the usual default settings of ram and test the chip out with a higher multiplier and lower fsb to see where the chip maxes out.
