AMD Sempron 3100+ overclocking

[BAcon]

i dont think anyone was really arguing just disagreeing

thanks for clearing that up, i was aware of the 754's being 32bit versions but was unsure of the socket A variants.

Tbh the lower clocked 754 chips clock better, my 3200 claw clocked to 2.4ghz with 1.65v while my 3700 hits 2.6-2.65 before getting flakey at 1.65v

tho im on air and reluctant to buy a better cooler which wont perform significantly better than the retail one, will go phase sometime next year perhaps, cash permitting

people are even saying the newcastled chips like the 3000/3200 are clocking great to, the 2800 included

bang for buck the 3200 was far better, but i got the 3700 at a great price from the pcw componant sale thing 25% off

The Sempron will never be the "CPU to get". They are simply replacements for the Duron and Athlon XP. AMD is doing them because they want to stop making Duron and Athlon XP but realize they need a 32 bit low end CPU as long as Intel keeps on making them (P4, etc..).

My FX-53 is an A64 so obviously I did not say the A64 overclocks worse than the Sempron, I said that the 2800+ A64 doesn't overclock nearly as well as the 3100+ Sempron. There are a number of reasons for this, a few of which I touched on in earlier posts.

If I thought any of you were interested I'd enlighten you. Sorry to interupt your little club. Carry on...

The reason I like Hexus is that you tend to get an honest answer to an honest question. The cracks good, folk take the mick in a grown up sort of a way and theres none of the petty arguing like you get on other sites about whos more expert than who.

Yes, and as I keep saying like a broken record, where is your proof that the A64 2800 doesn't OC as well as the Sempron 3100? You can repeat it as often as you like, it doesn't make it true. Evidence, please.

The new socket 939 Athlon64 3000+ comes at 1.8Ghz and will hit 2.6Ghz

Those are 90nm though, so they're not directly comparable.

In terms of overclocking is there much difference between the socket A and the Socket 754 version? The socket A version would seem to offer a much cheaper bang per buck, assuming you can get the same kinda overclock on a socket a as a Socket 754 board.

[Rave]

The socket A Semprons should in theory OC as well as a Tbred Athlon XP, since that's basically what they are. They are not the same processor though, a Sempron 3100 will easily beat a Socket A Sempron running at the same speed.

Why because of the board?

[Rave]

No, because it's a different processor. Unlike all the other Semprons, the 3100 is based on the K8 core which is a newer and faster design.

How much faster is it though, 10-20%? Would a 3200 barton in a socket A board not be faster? for about the same if not less money.

The older 2800+ AP (C0 core revision, clawhammer with half the L2 disabled) do not overclock as well as the later true newcastle AX (CG core revision) 2800+s.

Recent CG core chips all tend to top out at roughly the same top speed, though it definatly varies a bit from chip to chip. There is nearly as much variance between two 3000+ as there is between a 2800+ and a 3200+, in terms of overclocking potential.

This 3000+ that I am using is totaly stable at 2.5GHz with 1.55v and the lapped retail heatsink. I've seen a 3400+ newcastle that did worse and a 2800+ that did just as well. Mostly luck of the draw.

A Sempron 3100+ is a better gaming processor than the 3200+ Athlon XP barton, even though it has half the cache and is clocked 400MHz slower. The on-die memory controler counts for ALOT.

Any links to XP vs Sempron?

You need a new board though...££££

Here is anadtechs DOOM 3 cpu compairision.

Here is X-bit labs real world game play compairison (as opposed to anandtechs timedemos) of CPUs in DOOM 3.

The sempron 3100+ is not in the later test, but by inference it should still beat out the 3200+ XP, if just barely.

I haven't really seen any other 3100+ vs XP compairisions out there. Compairing a Athlon 64 to the XPs should be pritty close.

[sparky191]

Theres a substantial cost difference between the two though.

[oralpain]

Not where I am.

Just take the perfromance and price into consideration and get the best bang for the buck as always.
