Back on topic, I encountered an issue with the processor. The processor and memory can run asynchronously, but the way the Shuttle AN35N-Ultra works, the memory speed can only be adjusted according to a percentage of the processor bus speed, and the percentages are not as flexible as I would like.

Hey, trust me, it's not an issue with your processor. More likely than not, it's your motherboard that's causing the problem. I've got the same mobo and it definately starts to become flaky beyond 200Mhz. I've got an unlocked Thorton (technically a Barton, since I re-enabled the extra 256K L2 cache) XP2200+ on it. It's rock solid and prime stable @ 12x200 running dual channel cl2-3-3-6. Hell, I can even run @ 12.5x200 for a good few hours before I see an error. But if I try to push even 1mhz beyond 200, I've got to back off at least cl2.5-4-4-8. I know it's got something to to with the chipset on these boards. I've heard of a few people taking this board to about 220-230 @ 1:1 fsb:mem ratio, but it took some serious voltage mods to get there. Oh, BTW, the Thorton XP2600+ is probably the 266FSB chip you listed because the AXDA2600KV3D is based on the Thouroughbred B core, not the Barton.

What type mem are you running?

Just ordered a mobile 2600+...we'll see how things go this weekend.

When you boost your FSB, do you need to worry about the PCI bus operating out of spec? Or is that handled independently from the FSB these days?

New Update:
I received my SP-97 yesterday and my EP-8RDA3+ w 2400+ still wouldn't go over an 8 multiplier no matter what the voltage or FSB. Today I dropped the FSB all the way down to 100 and started bumping the multiplier up. I got all the way to 13 with it running stable at 1.6 volts. I tried 133 and still had 13. Tried 166 and had to drop down to 12. Tried for 200 and had to drop it down to 11. Still, it's running stable at 200x11 and I know my memory can do 215 stably. I'm letting it burn in some more at this speed. This is still at 1.6 vCore and 42c idle, so I think I probably can go higher.

nForce boards can lock PCI & AGP bus freq, Via can't (not even KT600), and some Sis can IIRC... don't remember WHICH SIS though.

 

[huesmann]

Is the nForce setting in the BIOS? What should I be looking for? I have an nForce2 Ultra400 board.

You don't mention your board nor do I have exposure or memory of ALL nForce boards so I can't be specific, but yes, in the bios, on bus speed or system chipset parameters page, IIRC... the setting name should be a good clue.

 

[huesmann]

Epox EP-8RDA3+ if it matters.

Might be an "AGP Frequency" setting in the Advanced Chipset screen, other than that i don't know.

 

[chinkgai]

got my 2600+ with my sp97 and enermax fan, i can do 200x12.5@1.85 (1.79-1.82 actual) giving me 2505.10ghz and i am prime stable for 7 hours (havent had a chance to run it longer yet)

have not been able to get it stable at 2.6ghz, and i duno what it may be, but it reboots by itself after 2-5 min, my psu maybe? duno, i got a antec trueblue 480 so i thot i should be able to handle this sort of power, i think i jes need higher fsb and lower multiplier

oh with an open case i am 22 case idle and 34 cpu idle at night time (with window open) and 44 full load with 26 case

all this on pc2700 ram and nf7-s 2.0

stepping is iqyha btw

have a gig of mushkin 3500 level one black on its way via ups, will try for 2600 then

 

[hytek369]

what is better?

IQYHA or IQZFA?

i started a thread here for results.

If these chips are supposed to run cooler, can a HSF for a 1700+ be reused?

these do well, EXTREMELY QUIET, and are pretty cheap, but not the best for high overclocking

lobadobadingdong made good suggestion but for slightly more dough the next value might be
ALX-800 @ SVC $16, though IIRC it was on sale a week or two ago for $13. It includes one of the more critical elements for good o'c (besides accepting large fan), a lot of copper on the bottom, but it doesn't come with a fan, I suggest putting ~2400 RPM on it, like Delta, NMB, etc or Panaflo L1A for lower noise.

 

[Seizure]

ok guys. Hit me with the truth. What would I expect to get if I slap one of these Mobile 2400+ or 2500+ on my


Asus A7N8X-Deluxe

edit: Crucial 2x256 PC2100 CL 2.5 - 3 - 3 - 6

Alpha Pal 8045 heatsink with a 32 CFM fan on top.
Thermaltake purepower 480 watt PSU


I know the Ram is going to be the main bottleneck. But how far do you think i can push the Mobile Bartons?

 

[mindless1]

Seizure, buy some memory. nForce2 is best at synchronous memory and FSB speeds so without newer memory you'd be looking at something like 24X multi and 110+MHz FSB, memory bus (whatever the ram'll do stabily).

the 24x and 110+ mhz your referring to is the Ram right?

What about the CPU? How far can I overclock?

I have a 1.4ghz t-bird right now, and I'm just doing a $70 cpu upgrade to hold me off until Athlon64 becomes more affordable or when Longhorn comes out. That's like 2 years from now and obviously I don't want to upgrade my ram until maybe DDR2 comes out.

No, 24x110 is CPU speed, with 110 being BOTH memory and FSB, "synchronous". Our crystal balls cannot predict your max overclock, you'll just have to try it and see. 2.4GHz should be attainable with an average chip, decent heatsink.

It's your call, i can't imagine wanting to run PC1600 memory for a couple more years but if all you're willing to spend is $70, then sure, the CPU is the way to go.

 

[Seizure]

so the 110 mhz is my FSB. The chip can support 200 mhz right for an effecitve 400 mhz?

 

[rvr2k3]

Why did someone say that the 2500 is the poorest OC'er of these chips? I just ordered two of these.

Update. I actually have PC2100 ram according to CPU-Z. So how far can I realisically push now? Can I hit 200 FSB?

If running XP or 2k, go to start, control panel, system properties, advanced, start up and recovery, and uncheck "Automatically Restart".

However, if you O'clocked too high there is a chance that bad data has already been written to your XP install corrupting it. I had this happen trying to hit 2.4 ghz on a Duron 1.8 ghz. It trashed my windows install.

Good luck and remember to always boot into MemTest rather than the OS when o'clocking till you are sure Memtest is clear. . .

Dang nice tip. Thanks

 

[Seizure]

After reading some more. I think 145-150mhz Might be more realistic. but my Asus A7n8x from what I read has their multipliers maxed out at 12.5 So 12.5 x 150 = 1875. So what is that? Barton 2800+?

 

[Seizure]

bumpity bump for my answer as my AMD Mobile 2400+ arrived today.

 

[mindless1]

Seizure, the answer is no, you can't assume 145MHz but it might be possible, you have to test it and see. If multipliers over 12.5 aren't available then there are ways around that, like burning a bridge or two or maybe a wire mod to bump chip up past 12.5X, preferriby to only 13.5 then adjust further with upper range then enabled in bios. Whatever XP speed you end up with, plus the bridge burning or wire tricks, can be Googled.
