Ddr2 @ 1-1-1-1 by kyosen

[Aerou]

if the comparison shots 333 to 111 are true, I'm beginning to get far less sceptical, thats insane, ...
NOW TRULY : IS IT EVEN POSSIBLE? ih yes .... the nForce Intel is

[M.Beier]

Tony, sure, but still, it looks cool

Kyosen = HW god, sierra, go away, we want Kyosen in here hehe

Technology sometimes makes what was once considered impossible possible. For many years, people thought the multiplier lock on Intel CPU's was unbreakable. Then along came SpeedStep and suddenly everything changed.

thats not really a fair comparison.
speedstep (EIST) is something that had to be designed and added to the chip, not something that was always there but unusable... which is why say a old northwood, can't use EIST, and still have locked multipliers.

its obvious that Intel processors are locked from a Bios level...
that became clear when the 3.4E 478 prescotts were "accidentally" unlocked to 14, on some Asus boards, if you used a bios, that came out before prescotts...
but other then this, theres never been a way to unlock all intel processors.

even pentium D's today can't be unlocked (manipluated would be a better word), cause they dont have EIST.

getting ram to cas 1 and such... thats always been a option for ram... not a easy option, but its a option, not cause something was added to the ram to make it possible, like EIST...

it is actually lock by mobo bios. not by intel CPU...
mobo RD can also open the intel CPU MP if RD wants to do it..... but lose job 4ever!


like x6800 is 6-20 on p5wdh but it is 6-11 on some other mobo

@Kunaak
I was speaking in general terms. Some things are definitely impossible. But every time I hear someone say something is technologically impossible, I smile. Time has a way of proving people wrong.

Kyosen = HW god, sierra, go away, we want Kyosen in here hehe

Okay I will go away. But you probably would have never seen these screenshots unless I had posted them. I did ask kyosen to join the discussion here. It's 7AM right now in Japan. He may be asleep.

How bout 0-0-0-0

I like it, he's doing a good job exploring something many would never try.

[[cTx]Philosophy]

There still is the fact that times were faster @ 1-2-1-1 which im guessing is 3-2-3-3 or am i missing somethign here..

There are no intel boards that allow for 1T?

I never knew this, and thats why im AMD fanboi, until the roe rig arrives at doorstep..

[IluvIntel]

I have the Gigabyte GA-965P-DQ6 board with F4d beta bios, and even with official F3 bios, my DDR2 timing options were able to get down to 3-1-1-1-1.
But CPUZ v1.36 always report 3-3-3-9..
I really need a program from windows for screenshots etc that can be as accurate as possible with true DDR2 timings...
Can't believe here we are more than 2 years after DDR2 on markets and no proper program can reliable report correctly....

[Dynasty]

awesome stuff Kyosen

[maverik-sg1]

Nive work - what is the best CPU FSB Achieved on this board so far?

The jump doesn't look big enough in the comparo. Looks like 3-2-3- vs 3-3-3. The 1's being 3's in reality. Just a guess. tRCD 2 is definitely very difficult on GMH and GKX, but its doable at low speeds like that.

[M.Beier]

Gautam, Im not sure, but I belive its very easy to run 2 with the 5400UL, its D9DQ (aint that the one?) - anyhow the first and well known fatty chip from the old BBmods thread, I belive my ram has that chip (havnt checked the chips, but its on the list..) and they run 3-2-2-4 at 43xmhz with just 2.4v - but no way of them hitting the 600mhz, tops around 530 4-3-2-4

[Dynasty]

its D9DQ (aint that the one?)

yep....D9DQT/W are fat body D9's they are the BH-5 for DDR2..........

[M.Beier]

yep....D9DQT/W are fat body D9's they are the BH-5 for DDR2..........

Great..
Now tell me, what would you prefer, 2*1GB of D9DQT/W or 2*1GB D9GMH??

[Dynasty]

Great..
Now tell me, what would you prefer, 2*1GB of D9DQT/W or 2*1GB D9GMH??

I would take fat body Micron's anyday over the newer GMH/GKX stuff....

But, thats just my preference....

Agreed.

I got a killer set of 5400UL here that does 470 4-2-2-x, but being just 2x512, gets outscored by my much cheaper D9GMH. Of course I'd love to get my hands on a 2 gig set of DQW or DQT, but I guess you can't always have it all. :-/

So yes, 2's are pretty easy on DQW/DQT, but GMH and GKX are completely different animals. (Considering how little I paid for mine, I suppose I shouldn't be complaining)

[M.Beier]

But..
If I can hit the freq I can, is it then pretty certain I got some of those chips on my mem, cause frankly, I must admit, I like this ram and dont wanna waste 'em, especially not since they're from USA and I live in Europe.. (I fear pulling of heatspreader will pull of chips as well, havnt done it ever myself, but seen it, and its a damn shame)

Thing is - other threads talk about BE6 or something' but I've heard that its only the old kits that has D9DQ..
But I kinda' know its not GMH or Elpida since its never been used on these kind of mem

[Dynasty]

what rev. are they ?........

[Gautam]

1.2, no substitute.

M.Beier, DO NOT pull the spreaders. You've obviously got D9DQT or D9DQW. Guard those sticks with your life.

[M.Beier]

Great

Was a pair of 322$ sticks as far as I remember

Pretty neat buy, aye?

They are definitely keepers.......

[Charles Wirth]

If you look at the screen shot of the monitor. I have done CAS2 on C19A and XE as well.

A latency screen shot would be nice, should be very close to best A64 ODMC.

[IluvIntel]

I got Corsair 8000UL's rev1.1 & 5400UL's rev1.2 - but both sets only 512mb sticks. Which ones can handle the highest bandwidth and tightest timings or are they pretty much the same...

I'm asking because my Gigabyte GA-965P-DQ6 mobo has option of running DDR2 @ 3-1-1-1-1. Cas 3 is as low as it can go.

[ZX7891]

A memory engineer told me that CAS 1 is physically impossible. He explained it but this was a while ago

[Jaco]

it looks nice, but seriously, 1 - 1 - 1 - 1
Do you really believe this ?
