Cell-SHOCKS ag. DDR3-2000 7-6-5-18 1T Prime_Pi Stable

[saaya]

I still have trouble to get 32m stable at above 900MHz, but I blame the board for that. It seems like the NB is stressed a lot with the memory running that high. I can run 32m stable with memory at 750MHz and a FSB of 525MHz with 1.4VMCH. To boot at 450MHz with RAM running DDR3 1800 I already need about 1.6V on the MCH to even boot into windows.

I didn't have much time so far, so I tried a couple of different settings with 1M to get a slight idea what is possible and what is not.
I will do more testing with 32m over the weekend, here is what I have so far:

Edit: All tests were done with 2,24 V Vdimm. I know I am a jerk Will try with less voltage tonight. I have a strong feeling it is the board limiting me and not the RAM, so the settings below will most likely run with less Vdimm too.

the 544 is great
looks like nobody ran 544 with ddr3 before, so this is the WR, highest 544
congratulations!!!

its quite high too, i didnt even think 555 could get that high we need to bump up trcd to 6 as well to get decent speeds with cas6. well at least that was my experience. victors 555 really caught me by surprise and this is even better

I don't think Asus engineers didn't think of running 900MHz on the memory when they designed the board. Same for Intel and the chipset

thats probabaly true
if it helps, i checked on one of the p5k3s and 1800+ boots with 1.4v chipset voltage, havent tested for stability but i could bench in windows.

so it looks like your board is a dud...
is it an ES board? maybe an early sample with an early p35 nb?
Several early ddr3 boards couldnt get above 1500 memspeed and im pretty sure its the chipset. P35 first launched for ddr2 boards, so maybe gigabyte and others used those early chips for their ddr3 boards as well and then noticed that those early nbs integrated ddr3 mem controller sucks.
asus seems to have used the latest p35 nbs even for their early ddr3 boards, maybe they noticed this or they always keep their warehouses tidy and empty and hence didnt have older stock.

anyways, i hope intel is going to bin p35 as well and not just x38.
x38 is just too expensive and from what ive seen and heard so far not worth it compared to p35.

u workaholic!! :P u need to fix your bed first!

Hell yeah, no wonder you are tired all the time when you sleep in that bed
For those who dont know, i kinda broke fr3aks bed ^^
Now gorillakos, before you even start to b!tch at fr3ak, i tried to seduce him but he wouldnt give in, he loves you too much...

But you're doing justice to the good stuff from saaya da man

Just too bad the board sucks... hope you get a better board soon olli!

if you want to go above DDR3-1800-1900 with DDR3 RAM you need a CPU with very high FSB wall (500-520 MHz) and you have to try to raise the North Bridge Voltage, PLL voltage, and FSB Termination Voltage (obviously also vcore and vmem).

im not so sure about the pll voltage, does it really help you?
fsb wise or memory wise or cpu wise?
I bumped it up everytime i maxed out something but it never helped, so i left it at auto and i can reach 530fsb and 2ghz+ memspeed.
I guess it has to do with maxing out the cpu speed?
Thats the only thing i havent done yet

I am not so sure about the facts that Asus and Intel engineers didn't think of running 900MHz on the memory when they designed the boards, infact there are motherboards that are able to run memory above DDR3-2000 MHz (like P5K3 and Blitz Extreme). Obviously we are talking about benching sessions and not for daily use (but for daily use you could run for sure at DDR3-1600 or with some overvoltage at DDR3-1800).

well the blitz is gen2 of p35 ddr3, so already gen3 of p35. and i think the secret of the asus p5k3 boards clocking better than other ddr3 boards when they just came out was that they used the latest nbs and others used older stock.

Wasnt the first people who hit 2ghz with ddr3 asus engineers?
So yeah, they did know about it, but i think that was only weeks before the launch... i dont know but i think micron ddr3 arrived pretty late so asus probabaly didnt use it to test their boards. afaik there is no other ddr3 that can reach 2ghz, not even close, so i dont think asus knew about this and planned those high speeds when designing the p5k... but in the end only asus and micron will know

I agree about the fact that with these memories it could be better to have a chipset with default FSB of 400 MHz and similar processors able to run at 400 MHz as default.

yeah! not only this, but we need way more dividers or an un link mode like on 680! I really hope intel is working on this or nvidia will get a ddr3 chipset out soon... wait, i take that back, i hope nvidia releases a ddr3 chipset AS SOON AS THEY MANAGED TO GET RID OF ALL THE BUGS IN IT :P

And wouldnt it be cool if intel would release an Xtreme Edition cpu with a default fsb of 666?
Now THAT would rock! no more looking for high fsb capable cpus.
im sure there are cpus that can handle 666fsb and im sure intel could bin them...

sorry for the long post ^^
