athlon xp 2600 mobo choice

hello people

i have two mobos to choose from, both are ecs. one is the k7vza and the other is the k7vmm. the info i gathered about them leads me to think the k7vmm is the better board, and i'd like a second opinion on that.

I have an axda2600dk4d cpu, and i would like to use it on one of these two mobos. problem is, i looked up the cpu and it has a 333/166fsb, while the mobos fsbs are 200/266

is this a complete mismatch? am i better off using a duron 1200 or a duron 1300 on one of these 2 boards, to not use a cpu like the 2600 in vain?

I always say it's best to doublecheck.

These are both ECS boards? Apparently the K7VMM has a VIA KM266 chipset; it's surely the better board.

If you run the 2600+ at 133/266Mhz, you essentially make a 1700+ out of it. You might be able to overclock a little and get a 1800+ or 1900+ out of it...that's an absolute maybe.

Frankly, I'd use the Morgan core Duron in both boards and save the 2600+ for a board that'll support it.

that's what i've thought you'd say skip. thanks. i also have a duron 1300 but on the mobo manual it says it can only take up to duron 1200. why do you think that is? is that a bios factor that can be resolved by updating/flashing bios? i mean i'd like to get the best out of it, because i also have an ecs k7som+ so both these durons are about to be used up. the k7som+ can take the duron 1300 but that board just looks DumB it has no agp slot, just onboard video probably 64mb . so i'd wanna use the slowest duron, the 1200 on the k7som+, and the 1300 on the k7vmm. is the k7VZA better than the k7som+ ?

ok the k7vmm board does not power on when the clearcmos jumper is on the normal position. it powers on with it on the clear position though, what's the deal with that? it just powers on, i got no POST :(

ok i got it going. but guess what, used a pci video card, an 8mb sis vga card. and still, with the jumper on the 'wrong' side according to the manual. honestly, according to me, too. i always known that ecs has the normal cmos jumper close to the battery. and the clearcmos, away from the battery. and on this mobo it's the other way around. i guewss i can set the time in bios, and see if the data is saved on the next boot.

done, it's working off the agp now. i had to set bios to try agp first. that's kinda funny actually, i think it was supposed to work without that setting. i mean it tries pci first, fine, then moves on to agp :) but ecs has their ways. could it be because it has onboard video ? probably. either way, it's working fine. jumper setting for clearcmos is backwards, but it saved the time and date.

okay, i tried the duron 1300 on the k7vmm and it works, it says duron 1.3ghz during post. that means i don't need to upgrade bios along that line, right ?

what would happen if i ran the 1.3 duron at 133fsb from the jumpers? would it burn out ?

I'm pretty sure the motherboard won't do 133fsb. The Morgan core Duron runs at 1.75v Vcore and I've had 'em running at 1.85v...don't worry about it burning out. As you pass 65-70°C those Durons will slow down and stop responding. You get plenty of warning that something is wrong.

On both boards just try upping the fsb a little. You'll likely see problems with stability between 108 and 112Mhz fsb. I haven't read the manuals for these boards and don't know what options are available in bios. You'll likely need to increase Vcore voltage a little at about the 108Mhz mark.

Watch cpu temps closely if you try to OC these things.

"what would happen if i ran the 1.3 duron at 133fsb from the jumpers? would it burn out ?"

It won't burn out, it simply won't boot at that setting. Durons run at 100MHz...you might get it to run at 112MHz but that's about it. As you were told, Durons are very low end CPUs. They run at a lower FSB than the Athlon, AthlonXP or Sempron & only have a fraction of the L2 cache...64k vs 256k or 512k.

"i looked up the cpu and it has a 333/166fsb, while the mobos fsbs are 200/266
is this a complete mismatch?"

Yes, it is. Why are you have such a hard time with these FSB numbers? One more time...there is theoretical & there is actual. You have to know which is which. The actual is the lower number, it's called the frequency. The theoretical is the higher number, it's called the FSB.

100MHz (actual) = 200MHz FSB (theoretical)
133MHz (actual) = 266MHz FSB (theoretical)
166MHz (actual) = 333MHz FSB (theoretical)
200MHz (actual) = 400MHz FSB (theoretical)

If you see 200/266 it means 100/133. Your 2600+ is supposed to run at 166MHz. You *may* be able to run it in either of those boards, but it will run 25% slower than it's design speed.

Where are you getting all these crappy VIA based socket A boards from anyway? Can't you come up with something decent like a board based on the nForce2 chipset?

hahahahahha my man Jam went all out on me here :)))) bro I swear I absolutely got it DOWN all of it about the fsb rates, and my question was more like "can I oc that duron by setting the fsb on the mobo to 133?" I just didn't wanna say it that way cuz I know how oc-ing a duron sounds retarded these fkerz get really hot and they're worthles..

You've set me straight again though, now I understand, it won't boot. as far as the nvidia chipset, I got a hold of a 400fsb(ok200) Epox, and I have it at my electronics guy shop because the fool I got it from destroyed two circuits trying to fit a heatsink from another socket type onto the cpu. It'll be fixed and then I'ma want to hook up this axda2600 to that.

Dude my brother in law brought me his pc and there's nothing I can do to fix it. It has a socket 478 2.something pentium celeron in there, nice asus p4p800-x mobo, can't get it to boot for the life of me. no beeps, zilch.

I used the psu on my other systems, it's fine. wthell could have caused it to stop working like that, it's not a noname. he has no clue what a pc is on the inside so he definitely didn't open it up, it still had the seal stickers on the case. needless to say, dust gallore and dry cpu thermal paste. but celerons have that maxtemp shutdown thing, so I don't think it could have gone out from heat. i replaced paste, reapplied all back on, I even changed the northbridge paste. it goes on, fans spin, nothing else. could bios flash its damnself ?

jam, judging by what you told me a few days ago in regards to the ram best fitted for systems, i should be using 100mhz ram on this system. it has 2slots for sdram and 2slots for ddr.
ddr: i have around 10 sticks of ddr400, 256/512mb mainly
i also have two ddr266(pc133) sticks - 128mb each

sdram: three sticks of 256mb pc133
-two 128mb sticks of pc133
-two 64mb sticks of pc-100
-a bag of 32mb sticks:)

so as u can see if I were to use pc100 to match up the cpu fsb and be at 1:1, i'd have to use 2 64mb sticks of sdram.

-i saw an option in bios, where i can choose sdram type to be at 200mhz or 266mhz. is this the same idea, doublepumping? and so I can use two 256mb sticks of sdram pc133?

or what would be the best option overall efficient, i don't wanna be throwing away huge rams on a system that's not gonna use it well.

thanks

Sorry if I'm being a bit hard on you but knowing the numbers, what they represent & how they relate to each other is very important. Once you get that down, things will become much easier. Hey, we were all in the same boat at one time or another :)

As for your brother in law's PC, all I can tell you is to troubleshoot as best you can. As you said, those CPU's are almost impossible to overheat to death. The only way to fry them is to overvolt them. No beeps is a bad sign though. If you're confident the PSU is good, I say it's either the board or CPU. Does the northbridge get warm?

"judging by what you told me a few days ago in regards to the ram best fitted for systems, i should be using 100mhz ram on this system"

You should either use RAM to match the CPU frequency, in this case PC100 with the Duron running at 100MHz, or you can use higher rated RAM (PC133, DDR266, DDR333, DDR400) & just underclock it to 100MHz.

Why waste DDR400 on a Duron?

i used pc133 and underclocked it, it runs CRAZY fast man, i was so surprised. i used the duron1300 in it, with 256mb of ram. sp3, all the codecs, all the bsplay winamp ms--office etc installed, it flies i swear i benched it and it was on the same level with athlon 1800+ on the cpu/fpu scale. i guess that ram timing is important enough. thanks again.

That was about where SiSoft Sandra put my Duron1300 on a MSI K7T Turbo2 board.
