Both mATX boards would not be too overclockable on their own. The s754 board doesn't have an AGP lock. The mobile Athlons
can be overclocked on non-overclockable motherboards (I've done this) but not without a lot of work, planning and pre-testing on an overclockable motherboard to find the limits of the CPU.
Let me respond to various things said throughout this thread:
"Wonder which one would run better in stock and which one will run faster when moderately overclocked?"
I'd dare say that the s754 would win in both cases when paired with the respective motherboards mentioned. In fact, if the sA board doesn't have multiplier adjustments the mobile Athlon would just be working at 6x multiplier unless you do a wire mod.
"You are VERY wrong. There are endless reports of skt754 OC's that range from 260-300Mhz FSB with propper cooling."
You are VERY right... except for the fact that the board she listed is NOT what everyone else is using for those huge overclocks. It's like saying "there are endless reports of cars going from 0-60MPH in under 7 seconds." Sure there are, but that doesn't mean the econobox or minivan you just bought will do anywhere near that.
"I mostly use the system for business office applications, internet, photo viewing editing, downloading, burning CDs DVDs and maybe encoding video. Thus video card is not a concern since I won't be playing any game. But I need at least decent graphics for viewing and editing photos and videos."
Integrated video would be fine. Ignore the video card fanatics. I have a friend who is one. He even insists that machines he builds for family have capable 3D graphics even if he knows for a fact that they would only use it for web browsing and such. It seriously is like a compulsion for him.
"I am happy with it though it's not quiet. I spent quite sometime playing with it and now I just need a fan speed controller to lower the fan speed (hence the noice) when the system isn't running too hot."
Socket 754 chips should run cooler, meaning quieter fans.
Two questions for Irene:
1) Are you limited to the maTX form factor or does your case allow for standard ATX?
2) How "fixed" is that $150 budget? Not talking about doubling the cost, but is $20 more doable? Is $40 more doable?
If the answer to #1 is no and the answer to #2 is "not really" then I have some suggestions for you.
EPOX "EP-8KDA3I" $65.75 plus $1 shipping
I have this board and it is definately good for around 280MHz HTT, maybe as much as 300MHz (haven't lowered multiplier yet so don't know if I'm CPU or mobo limited). Sure, the DFI will spank it at 300-320MHz, but that $40 more can pay for a better CPU to begin with.
The board plus a retail Sempron 2600+ will cost just under $150 shipped (before tax, if applicable) and get you over 2.2GHz on an overclock with a nice, relatively quiet retail box HSF. The 2800+ just has more cache, not higher clock/mult.
How about just under $170? Add $20 for a 3000+ that has the higher 9x multiplier, giving you around 2.5GHz. I think at this point most people would realize that even socket A mobile Athlons start running out of breath. If both reach a 2.5GHz true clock speed, I'm putting my two dollars (Better Off Dead, LOL) on the socket 754 system.
How about just under $190? Add $40 for an A64 2800+ (make sure to get the "AX" one) that is just like the Sempron 3000+ except has quadruple the cache and 64 bit capability. Who doubts the performance of an Athlon 64 CPU running at a true clock speed of 2.5GHz or higher? This is the exact combo I have, the "AX" 2800+ and the linked Epox board. At 278MHz HTT for a true 2.5GHz the setup works nice and stable. At 300MHz HTT for a true 2.7GHz, Windows will BSOD. Haven't had time to find the exact limit of the setup, but 2.5GHz is nice for $190.
Only potential flaw in the pricing is added cost for a video card. Did your burnt-out motherboard use integrated video or did it have an AGP/PCI card that can be re-used? If no card, you can get a used low-end card for pretty cheap, just make sure that they are PCI or true AGP 4x/8x, or that they use 1.5v so you don't burn out the AGP slot. Brand new AGP cards with minor 3D gaming capabilities are available for under $30.
