Should I Go 939 Or 754?


Recommended Posts

I am just wondering on what type of A64 processor to get. I see on pricewatch, or at least it looks it to me, that the 754 has a 1600 FSB, and the 939 doesnt really list. I want to put together a really good overclocking system, and I dont know of which to go.

 

I am thinking as far as the mobo, I heard the best was the MSI NEO4 PLAT/SLI? I want to get one of those with dual 6800's in SLI.

 

I just dont know the difference in performance of the 754 vs 939..

 

Which do I choose????

S939 is better.

 

It supports dual channel mem, which is about 3% faster than single channel(that's ALOT in benchmarks), and you will be able to use Venice and San Diego's - and clock for clock they are faster than Claw/Newcastle/Winchester.

 

And as was mentioned, S754 doesn't support SLI.

 

Oh, skip the Neo4 and grab a DFI SLI-DR. They are a little tricky at 1st, but once you get the hang of it, they FLY!

You were wondering abotu bus speed aswell. that 1600 is the hyper transport bus speed (double pumped like the Athlon XP bus so it's actually 800) skt 754 boards for the most part are made to run 800mhz and 939 and 1000. With any halfway decent board you get a multiplier to control that bus speed and keep it from becoming unstable when you OC (speed is what some still call the FSB (stock 200) x the HT multiplier (default usualy 4x on a 754 5x on a 939 board for 800 and 1000 respectively.) Dont get confused though, the HT bus speed doesnt have anythign to do with CPU speed which is that same 200 x the CPU multiplier (3000+ A64 @ 1.8ghz, miltiplier is 9x for reference).

 

All other major differences have been mentioned (Dual channel/new cores/more upgradable), but 754 is still the ONLY mobile A64 platform used and I havent seen any 939 setups used by companies like HP yet.

 

basically your lookign for a performance system based on motherboard and other hardware choice so for you 939 is the ONLY option bc 754 should only be looked at for a low budget system (ie. 2600+ sempron 754 and nForce 3 mobo now, upgrade to 3200+ later when you get more money kind of thing).

 

In otherwords spend the few extra $$$ get the 939 and personally why the heck would you go SLI :lol: based on price/performance a single card setp is really the better option (unless ATI's verson is better supported)

WOW! Thanks alot guys! I really learned alot about that, I will definitely go with the 939 setup. Thats some great info! I am probably going to go with that DFI Lanparty mobo, as I read a few reviews on the net, and It was good for overclocking! Once again, thanks for all of your help! I would have probably made a wrong decision on this.

939 all the way. 754 will no longer be made soon. 939 has 1000 fsb , the 754 has 800 fsb if i'm correct.

Thats HTT speed and for the most part it's utterly irrelivant on a desktop system.

 

But, yeah at this point I would go 939, if ytou want to have any future upgradability.

 

You can still build a S754 system that will rival any S939 system performance wise, but that will change in the near future when AGP finally dies and dual core A64s are released.
