Sempron Dual core = G2 Goodness! ( 3.4Ghz 1M pi on water)

Well well, I picked one of these suckers up for a friends build, but she hasn't paid me .. for a while now, so i decided to have a quick play with it

Now though, I think i'll keep it!

Some specs for those not familiar with this new and rather rare little beast.. currently AMD's cheapest Dual core.

Sempron '2100' Dual core

Codename: "Brisbane????"

Factory Clock: 1800Mhz
Factory VID: 1.3vProcess 65nm
Stepping: G2:
L2 Cache: 2x 256Kb
Ht Link: 800Mhz (8x)
A standard CPU-Z shot, and stock performance.. Pretty slow single threaded, but decent competiton for the E1200..

Now for some OCing:!

No claims of great stabiliy here with these results, just a quick benching session really, but you get the idea..

Conditions:

Mainboard: Gigabye MA-790FX-DQ6
Ambient Temp: 25-26deg C

Firstly Just a Stock everything run, Only the RAM multi dropped back, (HTT left @ stock) All voltages left @ default.

STK HSF - 2970Mhz@ stk 1.30v, Resonably stable..

Next.. Some ambient Watercooling , Old Swifttech block.

I should appologise in advance for the lack of Temp readings.. Coretemp does not report proper temps on this Core.. Estimated load temps @ 1.4v on water are 50c.

Std Water - 3250Mhz@ 1.44v

And finally, We break out the Water chiller and go for gold.. The High HTT = a nasty coldbug, so we're limited to 5-10c water temps...

Chilled Water - 3360Mhz @1.48v

And here we have it, highest 1M stable:

Chilled Water - 3400MHz @ 1.488v

Not a bad time for a sempron, the RAM really helps :up:

Still, not a bad OVerclock.. IF this damn board had Clockgen/SetFSB friendly PLL I could have pushed for a 100% Suicide!, Why oh why did my DFI 590 board have to die :shakes:

Enjoy.. Look fwd to some others results if they decide to pick one up for a play.

Very nice mAJORD!

Awsome cpu score in 3DM06!

Probably the 256kb cache slowing down the sp1

were can you get these?im looking for something to hold me over so i can sell my 5000BE while they are still worth a little money

Isn't "Sherman" the code name for a 65nm single-core mobile CPU? I think CPU-Z might have the code wrong there.

Pretty impressive for a cheap Sempron :)

Very nice! Just wish it had more cache :(

Oh snap, 1.6GHz OC. Very nice indeed.

Sae question here, from what i read this Sempron dual cores are only for chinese market

Nice mAJORD!, Almost a 100% OC! Go for it with Easytune! In stock in sweden cheap as hell ;)

check it out, its available at newegg
http://www.newegg.com/Product/Produc...82E16819103260

a bit overpriced right now, but thats to be expected as its a new cpu

agree, its overpriced, the x2 4000+ 65W is 2$ cheaper and is clocked 500 mhz higher and has doubled l2 cache.

It's also available in Poland and it's cheaper than X2 4000+ (not much though) :)

China was primary market I think, but Chines will sell to anyone :p:

Thanks mAJORD for great test! Impressive OC for a Sempron!! :clap:

AMD strikes back!
That celeron dc id going down now;) (that what the 3dmark was maybe thinking-showing the INTEL chipset )
Excellent results,nice work:up:

OMG! I want one of those! :shocked:

Great score. :up:

Thanks for that, I was thinking it's a bit odd!

Good choice over X2 4000+ for overclock because 4000+ doesn't exist in Stepping G2.

But this "Brisbane????" have smaller cache... so they are same...

the smaller cache has little effect on most things it seems. Even Pi isn't too bad at all next to a G1 512k brissy.

@mAJORD.

nicee ;)

how do you think, 100% oc is possible with better cooling ? (ln2/di, small ss)

mAJORD, good work once again :up:

Scientia disassembled super pi to try to find out why intel is so fast at it and it hasn't really got anything to do with cache size or speed, it's more to do with legacy x87 instructions.
You might like to pop over for a read. :)
