AMD chipset SETI performance

Ok TeAm,

I'm doing a major renovation of my home PCs (yeah i know, a month after i upgraded them!! lol - so sue me, im an addict! 😉)

Currently I have an Athlon TBird @ 1.35GHz on a KT7A mobo (KT133A chipset) running at 135MHz (the mobo won't go above that at all!!!!!!) My main machine is an AthlonXP @1.55GHz on an MSI KT266A running at 147MHZ FSB (the memory timings are the most aggressive on both computers 😀)

I am building a machine for my sister's family (to add to their ageing PII 266) and have decided on a couple of the following approaches to take. I am selling my TBird 1.35GHz system to fund my upgrades This whole system is going, so for the purposes of this discussion, it can be ignored 🙂. I am going to give my sister my Athlon XP Processor only. Its a 1600+. I have so far decided that I will buy a KT133A mobo for her system, for the fact that DDR SDRAM is too expensive, and I can pick up a KT133A on the cheap. ($150AU... i know... it's still a crapload expensive FYI, the average KT266A mobo in Oz retails for about $220-230AU at the cheapest online shops! 🙁)

What i was considering as an alternative, was to get an nForce chipset mobo. Now, how much faster is an nForce in SETI than a KT133A or even a KT266A?? I don't really wanna get an nForce, cos I was hoping to offload my Geforce 2 GTS to my sister so I could pick up a GF3TI200... so yeah. Just wondering on the relative speeds of these Mobos running with Athlon XPs for SETI.

Now, my 3rd question... after much procrastination, I have decided to go the Dual AMD route!!! WOOHOO!! 😀 BUT! I'm a cheapass... 😉 so i wanna put in Athlon XPs running at 1.53GHz unoverclocked. Which mobos out there let me overclock the FSB AND the VCore? I read some reviews of the MSI and saw IsOs thread on the Asus (heheh... IsOs and Asus sound kinda similar! lol! ok ok.. its too late and im getting stoopid!) and both these mobos sounded quite unimpressive. Especially the MSI with it's lack of tweaks.

I want to get around 3:30 per WU at the highest on each CPU in my dual setup. Will this be achievable with any available Mobo (what about Gigabyte, Abit, Epox??) And I also wanna use AthlonXPs, not MPs... if possible that is.

Hopefully, these upgrades will give me a total of 28-30 WU/day from my non-schools fleet, which will be up from my current level of only 11/day from these non-school computers.

Any tips would be greatly appreciated!! I wanna hit 100WU/day EVERYDAY! 😀😀😀

First off, without DDR you wont reach sub 4 hours.
Second, the NForce is on par with KT266A, so if you can go that way its the same performance wise. (still need 2 DDR modules)
I cut almost a hour off my time, going from KT133A (A7V133) to KT266A (8KHA+) so its a lot better (now my times are aprox. 4.20 @ 1350 TB )

For the dual board you will have to check with others since i cant afford duals🙁
 
I didn't know that DDR made that much of a difference... but i mean, WOW. Thanks for the heads up... 😀

So the nForce generates roughly the same times as a KT266A? cool... i think the KT266A is the way to go in that case.

Thanks for the help Soni 🙂

More help is always appreciated however!! Keep the responses coming 🙂
 
If you are having ideas about dual cpu setups, you should forget the entire debate about SDRAM -vs- DDR, go the DDR route regardless what you get now, next month when you break down for the dual setup-(you know you want too) you'll already have the DDR ready to go. =)

 
From all of the reviews thus far the KT266A has been smacking down the nForce chipset. They are still having some issues with them. They will probably be straightened out later, but the nForce was never meant to be a performance board. It was meant for oem integrated use for mainstream users. Power users will always go with the KT266A over it.
