If 975 chipset has more ram divider, such as working 1066 divider.... it is very easy to out perforamce 680i. Just FSB450 and DDR2 1130.... damn that is killer 975....but how many 975 can do that XD!!!
If i have time tomorrow i will try like 3.7G, 3.8G. since for those two CPU speed i can do FSB 411 and 422 and DDR2 103x and 105x...hopefully with higher FSB and ram speed, it can easy over 680i.

Interesting,

I got a Bad Axe 2 incoming myself (when ZZF gets around to sending it) and I am gunning for 3.8GHz Orthos blend stable on air with a Tuniq 120 for at least 8hours. We'll see.

Getting over DDR 1100 would be nice. I know my ram is capable of 1150.

the point is 975 don't take over 108x normally XD

ever try 975 1:1 400mhz 3-3-3? might be interesting.

well try but don't thing the score will be better than 1066 ... but who knows XD

Usually the mobo chipset comparisons have the memory timings and speed exactly the same. I'll assume the point here is that the same memory sticks perform at higher speeds and tighter timings on the 680i, but it only gives the 680i the ability keep up with the 975x in these benches. Even in the memory intensive Pi 32M 680i doesn't really gain much of a lead. Still with the average stable FSB on 680i being higher than 975x, its likely that not only will 680i users be able to drive their memory speeds higher but their CPUs as well. All of this within weeks of the birth of the mobos. Hard to argue that 680i looks like the clear winner in the long run for people who frequent XS. For those who don't like to tweak and use single Nvidia video cards, 975 and 965 might be a better solution at default settings.

LOL 680i = Pwnd

I had better score with my 965 compared to my 680i.

The DQ6 is a damn fast mobo and should match lots of 975x chipset or even sometimes beat them

that is exactly right, thinking 680i is around 230~250 for P5N32-E and same as P5WDH or ROG vs WS PRO.
however, with same ram, 680i both speed and timing are better then 975. also 680i divider gives more options than 975

ex: FSB400 for 975 = 1000 1067(can't use) 1200.....
FSB400 for 680i = 1000,101x, 103x, 1066, 108x, 1100, 113x, 115x, 117x, 1200

damn we can find the best overclocking for ram on 680i easy!

i do think when 975 @ over FSB400~440 will be much faster then 680i
that i am going to test tonight.

also.... think about 6x0i chipset later on... without SLi ..... maybe like $180~160.... if that is right.... 975 / 965 = hard to sell XD

Nice write-up denny, this is the sort of comparison I've been looking forward to. Most of the other mini-reviews I've seen have been comparing 1t vs 2t etc and while 1t is nice and certainly quick you just can't get the memory to clock high enough when running 1t to be that useful.

I'm looking forward to your high FSB tests, are you going to be running 1:1 tests as well as the ratios?

Very nice result!

Can you tell me where I can get this BIOS that you use?

Thanks for sharing your results! :)

OK here is 3.7G by pulling FSB
when 975 pulling FSB, memory speed is pulling too
but 680i is not


3.7G 32M

once FSB for 975 reaches 411 & memory to 103x, score difference becomes small
very interesting to see what is FSB423 between 680i and 975, that is sth 965 can't compare (after FSB400, 965 performance decreases)

what is the best mobo 975????

thanks

Can your RAM handle a 1T Command Rate? You'd get even better performance.

1T on 1200, you must be kidding me!
800 3-3-3 1T i might give a try later

OK here is 3.8G by pulling FSB

interesting

I guess it's the P5WDG2 WS PRO. I'm not sure though.

what do you guys think about badaxe2? not many have it :(
i should get my badaxe2 next week

how much is vNB voltage on 975x. Over 410 fsb I could never get 4:5 ratio to work.

1.6 VFSB, 1.7VMCH
memory 2.7v
on 975

nice...


i'd really like to see 1:1 3-3-3 on 975 and same on 680i only 1t at 411FSB if you can find the time. :)

any 3-3-3 1:1 on 975?
and 680i 1T on what FSB? ram speed?

1t at 411.. or 1:1 ratio...

but i suppose you can use any ram speed you want. You don't have to do the testing for me, i was just curious to see how the two performed at equal clocks with uber tight timings, as 975 is best at tight timings in 1:1 with high fsb.

denny this is how i see it

do MAX OCs on current cooling on both 680i and 975x....whatever the max CPU MHz they can pull and max RAM MHz and latency and THEN let's see who takes it out...........

that's is also as important as 1:1 comparisons

nice info, im planning to buy badaxe2 more and more..

ok, let's compare with 975 and 680i with QX6700
Normally, QX6700 can't do high FSB with those two boards.
for 975, the average FSB for QX6700 is 350~380
and for 680i, averager is between 300 to 333



680i 3.85G 32M

975 3.85G 32M

975 3.78G 3Dmark06

http://www.iamxtreme.net/mobo/680i/975_11.jpg



if you check my test very detail everytime, you will see that

1.For 3Dmark06, CPU score and SM3 score are 680i > 975, SM2 is 975 > 680i
2.FSB for 680i is not very important, you see, 29x FSB 680i has better 32M time and even 300 extra cpu score compare with 350FSB 975.......

those are good comparisons

so are you saying 680i can clock RAM higher and at tighter latencies :)

with any FSB
you can do 400/1200, 352/1200, 533/1200, 111/1200, 23423/1200, xxxxx/1200

any kind of FSB you can do DDR2 1200.
but of cuz sometime is not 1200 but close (like 1181, 1192, 1179.. divider issue)

yeah i'm aware of that

i guess what you're saying is that with 680i you can ALWAYS max out your RAM regardless of FSB which is :woot: great heh

can you let us know if there is any difference in clocking RAM between 975 and 680i chipsets anyways

like? sorry i am not quite get it!

i am trying to find the best FSB for 680i now


edit, just found out 1699 and 1700 are the breaking line
FSB 1699 are good and fast 32M but FSB 1700 (425) sux

i am asking if you can compare RAM overclocking on 975 vs 680 pls

i did, max ram overclock with 2.7v on 975 is 108x CL4-4-3-x
on 680i 2.5v is 1200 CL4-3-3-x

I got this....Not good 32m though:(

actually very bad
the best clocking FSB is 1699, over 1700+ = bad
i wonder what is next max FSB, maybe 1999 or 2299.... but don;t think chipset can take it

here is the proof that 1699 & 1700 FSB break line

1699FSB (424.7) fast 32M

http://www.iamxtreme.net/mobo/680i/680i_12.jpg




1700FSB (425) slow 32M

http://www.iamxtreme.net/mobo/680i/680i_13.jpg




anything above 1700+ are kinda useless now

here is 1T max overclock vs 2T max overclok on ram in 680i

1T 850 3-3-3 2.5v

http://www.iamxtreme.net/mobo/680i/680i_14.jpg





2T 1274 5-4-3 2.5v

http://www.iamxtreme.net/mobo/680i/680i_15.jpg







btw pulling memory and lower latency = useless too...
not even 1sec gain from 1200 4-3-3 to 1274 5-4-3

Nice comparisons. But 1.7v seems like a lot for 3.8GHz. Of course Asus Probe is usually not very accurate.

well, this CPU does 1.55v 4G 32M
but just lazy to change vcore... hahaha

looks like the bios needs some work for RAM to be tweaked better
