D975XBX Badaxe 1333fsb and 4:5

[guess2098]

interesting 20s faster than my 3810mhz time of 13min 49s with 1067fsb strap and 2x512mb sticks heh

1GBx2 is a little bit faster than 2x512 hehehehehe

[ssnseawolf]

Not bad.

I'm pretty sure that 1333 with 667 divider is 1:1. According to CPU-Z, same sticks of Teamgroup D9 2X1GB do:

- 420Mhz 3-3-2 @ 2.6V with 1066/667
- 525Mhz 3-3-2 @ 2.6V with 1333/667

If 4:5 is actually 1:1 at FSB1333, than in both cases the RAM is running at 420Mhz.

That makes a lot of sense.

Until someone has actually measured the Memory clock in 1333:667 mode (which quite logically should be 1:1) there is not much point in this discussion.

I can confirm that
I think 1066/533 is 1:1 and 1333/667 is 1:1 too
But unfortunally CHIPSET INTERNAL LATENCY is much worse @ 1333 than @ 1066 and performace is still crappy.
I need 3522MHz (1333/667) to have similar performace like 3388MHz (1066/533) - mems timings identical /meansured in PI 1M&16M/

I've posted this in another thread also:

E6600 @ 4.3Ghz, 2X 7900GTX @ 850/1070
FSB 1333 + RAM @ 597 3-4-3-4 vs FSB1066 + RAM @ 477 3-4-3-4 (RAM clocks reported by CPU-Z)




If what i've said before applies and the RAM is actually running at the same clocks in both cases, there's still something else involved since LH gets a consistent boost with FSB1066. On a side note, i needed higher voltages on MCH/RAM to run at FSB1066 setting.

Hey guys, nice thread, I am having problems with the 1333FSB strap on my latest bad axe (last one died)
It does the power off thing but seems to keep booting at 1066 whatever settings I try. Can anyone advise the secret to getting it to work on is this just becuase of the latest BIOS version 1304?
I can get 400FSB x8 prime stable, with +50% limit on 1066 strap using this unmodded board and 1304, 400x9 wont even work with 1.45 vcore! 266x13 is 90% stable at stock vcore also. This is an X6800 (es) Step 5 B1.

Stumbled on to this last night with IDCC.

Look at this below. I'm running the 1333 strap + 9% = 363fsb with mem at 667 which should be 4:5 ratio or 454MHz on the mem.

CPUz says it's 454Mhz.
IDCC says mem is DDR2 727 or 363Mhz which is 1:1 ratio

Which one is right

[bachus_anonym]

Bingo Blue078!

It looks like you might have just delivered THE confirmation we all needed to prove what some of us suspected (DDR2-667 ratio and 1333fsb strap = 1:1, not 4:5)! Pretty funny, that nobody else with BadAxe has actually tried this soft before

[Supertim0r]

installing it right now...

edit : yes it show the "REAL" memory speed, nice find Blue078

[Blue078]

Still at 1333 strap but this time chose the 533 mem option.

Now which is right ?

[Blue078]

In both cases 533 and 667 sandra show the same as IDCC.

IDDC again 5:4 instead of 1:1. The suspicion some of us had was that at 1333FSB strap (333Mhz) memory ratios would look like this (I'm not sure If DDR2-800 can be selected on BadAxe as 975X does not officially support DDR2-800):

DDR2-533 --> 5:4 (266MHz)
DDR2-667 --> 1:1 (333MHz)
DDR2-800 --> 4:5 (400MHz)

[Blue078]

I wasn't trying to prove anyone right or wrong.

I've lost 60fps in CS:S's VST moving from 3800-X2/SLI-D/1900XTX to E6700/BadAxe/1900XTX. and have been trying every BIOS combo trying to sort out the loss. Then I stumbled on to this. My next step is to drop back to the 1066 strap and see if I pick up the lost FPS.

No worries... You have actually made all of us a HUGE favor by showing what you have found out! We have had quite a debate here regarding actual memory frequency and ratios when forcing 1333 strap from BadAxe's BIOS.
Thanks man!

[Blue078]

OK their is a 800 mem option showing while set to 1333 strap. Would like to see what ratio it comes up with but cant get the board to POST even with 5-5-5-15 timings if I choose the 800 option

I'm running the Corsair 8500C5's and haven't had any trouble running them in the 1066 strap at 504MHz 5-5-4-14 so not so sure why the no POST..

Sorry someone with better mem will have to find this one out

Edited goofed on the 6-6 changed to 5-5

[Micutzu]

Nice find Blue078
Bad Axe doesn't boot with the FSB1333 + DDR800 setting btw.

...this isn't the first time that CPUz has 'read' the wrong settings.

Not to bash the program (we'd be practically no where without it, let's be honest), but its methods of calculating speeds are JUST THAT....calculations based on apparent set settings. *NOT* readings of actual speeds.

Now, it's not all CPUz's fault (in fact, it's mostly the mobo makers') that this causes problems: motherboard makers don't necessarily use a standard for clock and ratio settings....if a setting name directly corresponded to what it should do (like the "180" mem ratio on K8, especially when used with the 11x multi to get "/13" mem divider), then CPUz would be right....but since a BIOS setting is only a pretty face, lots of ugly stuff can happen and CPUz won't detect it until someone comes along and shows the TRUE speeds, so that the program can be selectively reprogrammed

That's where we come in....great find Blue078

I see some folks say 4:5 on 1333fsb isn't working and think it's 1:1 but.........

I thought reason why Badaxe 4:5 can clock so much higher is that it is due to the less agressivenss of the MCH settings at 1333fsb to allow fsb to clock higher at least on badaxe... ?

Why else would at 1333fsb strap 1:1 is slower than 1333fsb strap 4:5 for me at same fsb and mem timings on cpu and ram ?

Hi,
divisor 667 of strap 1333 = 7:8 ??
divisor 533 of strap 1333 = 8:7 ??
is it possible??


sorry but my english is very poor

thanks

[eva2000]

1067fsb strap 533 = 1:1

Radiical chipset waterblock with fresh layer of Ceramique thermal paste on Intel Bad axe MCH/NB core (no volt mods still). Best of all I can now do 488mhz 4-4-3-5 at 2.2v with very tight tRFC value of 25!



With better MCH cooling seems my memory is flying even at 2.2v vdimm

Here's what clocks it took to break 15mins

[Tony]

I can't believe you all though 667 in 1333 strap was 4:5...come on..LOL

in 1066 strap 533 = 1:1
in 1333 strap 667= 1:1

I publish an article trying to explain this crap showing how the strap changes the memory ratio's and you still debate on and on on an on an on...

So I will cut thru the crap and tell you all what you need the motherboard to do.

You need the bios to force the 1333 strap on the clockgenerator, this will allow it to scale easy over 370fsb....normally the max will be 100fsb over this.

You need the bios to NOT set the 1333 strap on the NB but to set the 1066 strap on the NB instead, you will still have the awesome speed the ram can do but you may have to run 1:1 instead of 4:5.

The sooner RD600 comes out the better, this strap 5h1t is killing me now..LOL

Hahaha, that's what the whole fuss was about and some of us wanted to prove in wrong, Tony! It was that, CPU-Z made man, many people believe (starting with early adopters of BadAxe), that 1333fsb strap forced from BIOS and ratio DDR2-667 selected at the same time, yielded 4:5. That's what Memory Tab was showing, indicating huge (and impossible) CAS3 overclocks and some of us were trying to prove that it was wrong - correct info there should be 1:1. I think you have misunderstood the whole thing
But I'm glad we're finally on the same page now

[Onepagebook]

1GBx2 is a little bit faster than 2x512 hehehehehe

NOT just little bit, it's dang A LOT

I may have been a little off base but you will notice cas3 clocks will be higher using 1333 strap, TRCD at 3 also will be possible where using 1066 will will have to losen to 4.

If you check the guide I wrote it shows what ratio's are available per strap, if I get time I will work out and add the special ram ratio's like you see on the asus etc and show how they get them.

Side note, if you get a 1333fsb CPU and you use one of the special ram ratio's you are actually forcing the NB to a different strap, so this may yield extra speed.
