Can you use all socket 754 cpus in all 754 mobos?

[Spike]

Hey

I was using a 3gig Athlon 64 in my Asus K8V-x mobo. I've borrowed a 3.4 gig Athlon 64 from my mate but it doesn't work for some reason (when I turn the power on the monitor doesn't boot up). The stepping is ADA3400AEP4AP. Is there any possible reason besides cpu damage? Could it be the 3.4 is dual core and incompatible or something?

Cheers!

Sometimes a bios upgrade is required to support a new CPU. Did you try clearing the CMOS to see if it'll boot? Is it a mobile CPU as some boards don't support them properly again without a BIOS update. Also it isn't a dual core as there are no socket 754 dual core CPUs.

Thanks str. I've tried clearing the CMOS but I'll upgrade the BIOS and see what happens. I'm not sure whether or not its a mobile CPU. I don't think so I'm not trying this in a laptop or anything.

Fingers crossed!

It's not a mobile cpu. It's also not 3.4ghz. 3400 is just it's code. It makes it roughly the same performance as a 3.4ghz P4. It is a 2.4ghz, 512kb L2 cache Newcastle core on the 130nm process.

You're right pastymuncher. Actually, I the BIOS displays the cpu as an AMD engineering model. Turns out it's complete crap, running at about the equivalent of a 1800+ Athlon. Switched back to my 3000+ instead and clocked it at 220*11 multiplier.

Engineering samples are like mobile 754 CPUs so they default to a 4 multiplier IIRC. If your motherboard allows it you can change the multiplier and run it at it's proper speed. Also it'll be multiplier unlocked meaning you can easily overclock with it by going above it's normal speed multiplier.

They can be a bit flaky though, and when I say "a bit" I mean "a lot"...
Probably best just giving it back to your mate or chucking it on the bay if hes not wanting it.
Most of the ES chips I have seen people use are flaky minimal/no overclock wastes.

220x11 is not a bad speed for your other chip.

Yea I was pleasantly surprised. I've never tried overclocking it before despite being into all that kinda stuff back in the day of 400Mhz AMDs hehe. Now Colin McRae Dirt is actually sorta playable! Well chuffed. Doesn't seem to get that hot either.

As for the engineering sample, I don't remember seeing an option for the multiplier in the BIOS. You could change CPU FSB and select CPU Mhz which I'm guessing is a multiplier setting disguised. Anyway I set it up for the correct settings for a 3400+ ran Sisoft Sandra to check how it was doing and it was the same as about a 1800+ chip, awful.

Thanks guys.
