Sempron overclocking fun!

[Hesky82]

Hi chaps, currently putting together a very very cheap pc for a friend and couldn’t help but find out what these new low power 65nm Semprons overclock like before I put it back to stock and pass it over to the new owner.

Well the chip is a Sempron LE-1620 64bit with 2.4g stock clock and cost just 25 quid for a retail box, here is what I got out of this little beasty with just the lowly 1.25v stock vcore and oem cooler!



Probably not prime stable one bit, but still 3.2g is pretty impressive for a Sempron imo

Unfortunately this NF405 based Abit motherboard I used for the cheap build is real limited when it comes to overclocking. All you can change is FSB and HTT multi, can’t change cpu multi or ram dividers and most annoying of all you can’t change the cpu vcore!!
Better ram would bring the pi time down a tad also I recon.

Would love to know what it could do with a good cooler and loads more voltage!

Nice clock. I didn't know that AMD had released more Sempron models. Also is CPU-Z correct in that the chip has 1mb of L2 cache?

 

[Hesky82]

yup, both the LE-1600 and LE-1620 have 1mb of level 2 cache, thats kind of what appealed to me as most the new LE’s have just 256KBs.
I thought the new version of CPU-Z would recognise these new cpus but I guess not, not yet anyway.

Possible re-badged Athlons then?

And that Super-Pi time is faster than any of the other AMD's in the forums database.

you sure?? Im not to up on AM2's tbh but my old single core 939skt 146 opteron could do a solid 26 second 1mb run

It certainly is an impressive clock. From what I can see, they're the F3 revision of K8 chips. If the F3 Athlon 64 X2's are anything to go by, these should be excellent clockers. Excellent clocking project though one would need to have a really tight budget not to be able to afford the extra £15 to go dual core.

Well the latest database anyway.

Great cheap overclock, good job

 

[Hesky82]

Well the latest database anyway.

looks like that database has been compiled pretty recently, I guess it’s just because many people dumped their fast AMD chips and focused on CD2's

@Mul, tbh any dual core would have been wasted, as this pc is only going to be used to surf the net, send emails and open the odd office app from time to time.
Cheapness and energy efficiency was kind of the build outlines, so probably going to run the cpu with CnQ enabled.
