Socket 754 vs. 939

[J_Tweedy]

Ive got a socket 754 albatron motherboard, and after nearly a year of problems i ve worked out that its because i have been trying to run all three dimm slots at ddr400- which ended up screwing something up.
Just wondering, if i got a socket 939 AGP motherboard (with a new cpu obviously) would i be able to run 3 sticks of ddr400 512mb ram all at their ddr400 speed?
Also, is an AGP voltage of 1.5V enough/fine for a leadtek 6800gt (a400gt tdh)?

you be able to run all 3 sticks on a socket 754 mobo no problems and yes it will run fine on a 939 mobo and agp voltage dosent matter it will run i would recommened getting a pci express 939 motherboard though so u wont have to upgrade for awhile but its your choice

asus has a great mobo for s939 and agp.

and dont bother listening to giant about the pci-e thing unless you want to buy a new card.

o yea i forgot about that asrock motherboard

 

[Revisedsoul]

not asrock(even though they do have one and are a subidary of asus)

here it is http://usa.asus.com/products4.aspx?l1=3&l2=15&l3=68&model=238&modelmenu=1

For someone like me, with an AGP card, 939 is a bad choice. This is because the only AGP 939 ASUS boards run off the VIA chipset, which is far inferior to the NForce.

well still hes better off with asrock so he wont have to upgrade his motherboard for awhile

 

[Revisedsoul]

id hate to say it but the via chipset isnt all that worse than the nforce. other than the little performance gains, the nforce does come with gigabit lan and hardware firewall.

and both would last him as long before buying a new gfx card

With the Athlon 64, most memory issues are related to the onboard controller on the CPU rather than the motherboard. Early versions you could not keep DDR400 speeds with the memory slots full. With the current CPUs most of which are 90nm, Socket 754 or 939, you won't have that limitation. You will want to check the core version (newcastle, san diego etc).

Ok, well cheers for the help- the motherboard i have atm is an Albatron K8Ultra-V Pro II which is newer than the cpu (which i got in Nov last year).
Basically what has happened is because i tried to run 3 sticks at ddr400, SOMETHING has stuffed up, and i just found out is wasn't the motherboard- i dont know what core the cpu is but its probably the newcastle or winchester.
I was going to go for socket 939 with a new venice core cpu (same speed as before-3200+) but i dont want to spend the money until i know that the old set up ive got is going to keep giving me problems.

btw: This is pretty poor on the part of AMD i think, as i at no point ever knew that running my memory this way would cause problems. Call it my noobishness if you want, but i was never under the impression that it would cause problems.

Intel's chipsets do it too. Just they mess with the latency (which is worse for games) instead of DDR speed. Its a limitation when they make the memory controller and rising need for memory more memory.

939

didn't read thread, there's no competition!

 

[J_Tweedy]

got my socket 754 processor working, well actually some technician did, but im running 1 gig at ddr333. Can i get something straight- 1 gig at 333, or 400 ok? (assuming i have the old amd64 cpu and mobo)

 

[duffers20]

It would be better if you had ram that was running at the same frequency as your cpu, your cpu will have a 200mhz FSB and you want your ram to also run at 200mhz, which is what DDR400 runs at.

 

[J_Tweedy]

thats what i thought but apparently with this older amd64 I can only run 1 stick at 400. Ah well, looks like im gonna have to go for 939 when i can afford it.

 

[Asus]

Are they the exact same sticks?

 

[J_Tweedy]

Yup, all Kingmax DDR-SDRAM 184 pin DDR400. One's newer, because i just bought it (hoping to run 1.5gig), and it has a different block layout, but it's still 8 each side like the others.

 

[russ_uk]

i have an amd althlon64 3200 (newcastle) running on an asus k8n mobo with 3 x 512 mem (kingston ddr400) and it is running at 400mhz , but if i upgrade to the lastest bios it only runs at 333mhz

 

[J_Tweedy]

hmm- ok. I could run 3 sticks at 400, but as i said it led to problems, currently running 2 sticks at 333, but ill have to wait till i get back my 3rd stick before i try anything.
