Uhm, when you return your memory to GEIL, do not give any other reasons beside the instability you've noticed. Just tell them that they do not run stable at an FSB of 400. They will know their stuff has a life-time guarantee (no need to remind them) and in doubt do you the favour of replacing them.
If you write you want to replace them because of that life-time guarantee (even when you mention it together with the instability) they might sense an abuse of their guarantee. Some shops then let their support take care of it (pulling you into a discussion) or even send you your old modules back and tell you that nothing would be wrong with them ... Once this happens, you can forget about it.

Quick question: Is the mobile XP with the Barton core a better option than the socket A Sempron 3000+ which is believed to have a Barton core, too? I can only find mobile XPs with an FSB of 266 whereas the Sempron 3000+ has atleast an FSB of 333. The chance of getting an overclockable CPU should be better when a higher FSB is guaranteed. The price of the Sempron also seems to be a bit more attractive - mobile CPUs are know to be a bit more expensive. Does anyone know if there is a difference in the CPUs packaging? I.e. if one of them is allowed to have a higher temperature or core voltage?

Your reasoning is incorrect about the FSB overclocking issue,the Athlon mobiles are unlocked ,so the rated FSB is irrelevant.
You can choose whatever multiplier you like with the XPMs (within reason & mbrd/RAM abilties).
As for the Sempron 3000 are you sure its a Barton core? ,I thought all Skt A Semprons were gonna use the T'bred B core?
[edit]After a quick google search it seems you are right (ignoring the S754 variant) it does seem to be the Barton core(another site seems to confirm it too).lol ,its old news <I hadn't realised! 😱
However with the Semp 3000 you 'll be stuck with a multiplier of x12 ,giving you 2.4GHz at 200FSB IF it can hit that.
XPMs 2500 & 2600s default vcore is 1.45v ,but they are the same core as the Barton so running at 1.65v would still keep it within AMDs def vcore for the Barton 'familiy'.
It just means the XPMs are much more likely to overclock well & with a lower voltage compared to the normal desktop Bartons😀

Hey sorry for the late post I've been too busy with school and work, still got exams next week 😛
I've tried those timings and have failed still.
geil replied said this:
Check to see if the timings are set at CAS 2.5-8-4-4 & try running memtest &
see if it detects any errors. You can download at www.memtest86.com .
I did the test and but I think I put the wrong ones, because my motherboard (NForce2 abit) doesn't have the 8 option it goes only up to 7
so I thought im suppose to do 2.5-4-4-8 so I did it and it did find errors lol, I don't know, I'm sure I'm doing something wrong.

He just gave you the numbers in an odd sequence ,the SDRAM Precharge/Tras goes over 11 ,at least it does on my nfrc2 mbrd😉
The RAM timings you set are right.
If you have the correct voltage to the RAM & if your still testing the RAM with CPU at (or very near to) default speeds and your mbrd supports 200FSB/RAM then the RAM is faulty unless the PSU is playing up or your mbrd is faulty!
Can you test the RAM in another rig?
If you don't have a multimeter you could eliminate the PSU by cranking the cpu upto 2Ghz but with a lower FSB ,say 166 or 133 & then testing with WC3 or 3dmark (that will be a greater load on the PSU than 1.8GHz with 200FSB,testing on memtest or Prime95)
I can't remember what's been said in this thread now😱 ,it's been a while!😉 ,a system spec refresh would be handy😉

For now its best if you test your RAM with the cpu at or near default speeds.
You said your RAM runs at 2.6v ,have you confirmed this with the bios settings?
Can you test the RAM in another rig?
Your not reading all my questions😛
Can you confirm the PSU voltages are ok?

Unfortunate ,but nm (re RAM testing)
PSU = Power Supplie Unit ,your ATX transformer
Btw its better if you can test the voltages with a mutlimeter but bios readings will have to do otherwise
Looking for the 3.3 ,5 & 12v line readings

This is quite an interesting thread. Assimilator1, did you order your 2500 mobile CPU from newegg.com? Just trying to get an idea of what batch I might get if I do order one.
I'm debating which Shuttle XPC to get and would like to get a budget minded setup, and these mobiles seem to take the cake. I don't think I can justify spending extra dollars (that could go into RAM or wireless network adaptor) for a s754 platform or a intel setup which would probably have a still expensive 2.4C chip (~$130). I'm not sure how far shuttle xpc motherboards overclock but I figure they are nice and cool and will do the job for the least amount of money at stock speeds anyway. Anything wrong with my logic?

Not AFAIK 😉
Btw I bought it from overclockers.co.uk ,I'm in the UK😉
I can't find my paper with the cpu numbers on atm , if you really want them lmk

Hello everyone.
I really want to get one of these babies, but I just can't seem to part with my 1700+ DLT3C yet for I don't think that the improvement will really be noticable.

It depends what sort of an increase your after ,I doubt very much that their'll be a visual increase in performance in games.It will defintiley increase your benchmark/FPS numbers ,questionable if that's worth it.
If you do much encoding,3Drendering or a Distributed Computing project then you will see an increase.
Though that of course depends how high it'll overclock!😉
If you managed to get 2.5GHz from an XPM2500 then that would be approximatley a 10% increase in clock speed ,& the extra cache would be worth about another 5% boost.If you don't manage 2.5GHz then it wouldn't be much of a boost at all.
Is that + ~15%(maybe) worth it to you?
Btw I went from an XP2400 @2.22GHz (177FSB) to an XPM2500 @2.52GHz & it cut S@H unit times from 2.3hrs to 2hrs.A 13% cut in times. (ah if only there was a x14.5 multi I'd run it faster!).It does run cooler though because of the lower vcore (1.66 vs 1.77)
Unfortunately I didn't benchmark anything else😉
Inccidently ,nice 1700 you've got!🙂 ,mine would 'only' do 2.04GHz without running at silly voltages.1.75v at that speed.

Sorry about that MegaWorks, I thought that was a little obvious 😉
Yes, this 1700 definately performs and no doubt there is more juice left in her. I've been running this configuration for just over a year now with no hitches. I suppose that is why this was/is one of the more highly sought after CPU's. You can still find them on EBay if you search for around $50CAN.
I've got it coupled with a NF7-S, which is still IMO the best XP board out there. Using a Aeroflow HSF for cooling the machine will run @ 37C idle with the 800Mhz OC. Fantastic platform!
About 6 months ago I took the CPU up to a full Ghz OC and the chip was fine with it but the ony thing holding me back was my ram.
I'm just far to cheap to get quality OCZ or CORSAIR - If you can believe it I'm using a 512 stick of DDR333 and a 512 stick of DDR400, @ 410. Both sticks are AZENRAM! It's scary that the ram is actually performing this well! No doubt with good ram I could kick it up to a 1Ghz OC no prob.
As it stands though, I think that you're right Assimilator1 regarding the cache being the only guaranteed increase in performance if in fact it did amount to 5% and then one would probably only notice it in a benching software.

wow very interesting
from what I've learned here in anandtech forums, I?ve realized that if you want to try to have an overclocked system and have it stable and running it at the certain speed that you want... Is alot of hassle and headaches
firs you gotta be lucky, than you gotta know exactly what you are doing, (not half ass). and when it comes to testing it for stability I really don't have the patients for it... It's a back and forth job, I know logically it?s smarter to get more out of what you actually paid for, but I went through a lot of headaches for this and I literally wanted to just throw my comp out of the window.
I guess it could be a hobby for some people, but not for me as a competitive gamer that needs to have a system absolutely stable at a particular time.
I thank everyone for their help I really appreciate it, especially megaworks who actually helped put my computer together.

I build an Athlon XP system for one of my friends two days ago, an Barton 2500+ oc @ 2300mhz 1.775v works super fine. He had the stock cooler on the heatsink and his temperatures where high at load setting, so I told him to install his SLK-800A with a 80mm Tornado fan. Tempertures where 58c load @ stock and now 47c load with the SLK-800 very impressive. Sorry to hear that you're leaving the overclocking world bde. 😛

Afraid so! 🙁
Btw you could just leave it at a known stable speed for gaming & o/c it when you have time & can be bothered 😉

BDE, your persistance is admirable. certainly you didnt waste your time, you learned lots. next time you'll get it right. in the mean time, i think you're right to sit back and enjoy your 2800.
Barkingmad, i think its time to let the K7 die and move on to the A64. the 90nm A64 3000 has come down in price to ~150 and the NF4 mobo's are SWWWWWWWWEEEEEEEEEEET.
