Sempron 3100 in an Asus A7v8x

[Guest]

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

Hello, All!

I currently have an Asus A7V8X m/b with an Athlon XP 2200+ (or maybe 2400+?)
rated at 2.2 mhz system which is oc'ed by about 12%.

I understand I can upgrade this to a Sempron 3000+.

Questions:

Will this chip work?
If that is all I change will I really see much difference in overall
performance?
Would it likely continue to be a stable mb/cpu combination at the oc I use?

Thanks.

Colonel Blip.

I think your current processor is the Model8 2400+. The FSB is
FSB266. A Sempron is FSB333. The Sempron P.R. rating is compared
to Celeron, while the Athlon P.R. rating is compared to a P4.
So, you cannot compare the Sempron numbers directly to your
current processor (i.e. speedup is not as great as you think).

The Sempron is supported by the A7V8X, but a certain revision
of board is needed, with the FSB333 sticker on the Northbridge.

The higher FSB will allow more bandwidth, when it comes to
fetching data from memory. Also, the larger cache on the 3000+
will help. The only question then, is whether your board
revision is good enough for the upgrade.

As for overclocking the A7V8X, I have no idea how much headroom
is left above FSB333. The higher you go, the more stress on
how the (single channel) memory is configured. At some point,
you may be limited to using a single stick of memory.

HTH,
