DDR2 vs DDR3 - ASUS Blitz Formula vs Blitz Extreme...CellShock Rams involved...

[The Stilt]

Here is dual channel run with adjusted ODT.



Since ODT cannot be adjusted (on Asus) from the bios and it is impossible to get in Windows without adjusting (if tCL is under 10CLK) it I have to boot with 470FSB and use clockgen to get higher. When booting under 500FSB the transaction booster / performance level must be loosen a bit because otherwise you won´t reach 500FSB. Of course when booting at 500FSB it will be automatically loosen as the "strap" changes at 500FSB.

ODT can actually be adjusted with tools available to public.
I use the good ol' WPCREDIT and Pmem combination for all of the adjustments.

Unfortunately my board seem to get worse and worse.
Few days ago I had no problem doing 2000MHz / 1T in single channel, today I cannot even get in to Windows with the same settings

There is no difference in MCH temps or voltage.
The chip just cannot do it any more.

Seems that using 1.8V will damage the MCH really fast. It is not a surprise thou, since it is a 90nm part and even the 975X (130nm) could be damaged with 1.8V+ in prolonged use.

I would like to see if there is any difference in ODT register configuration on Blitz compared to P5K3.

[dinos22]

so have you done any Pi tests
does it make any difference

shame about your board going a bit house

ODT does not have effect to bandwidth.
Adjusting it seem to make the DRAM more stable.

I don´t mind the board, P5E3 Deluxe is on the way

oh that's great
how much extra do you gain

you had some shocker dual channel results on that board
in all slots??

i assume you ran all for slots and found the fastest one for your tests

Some tests I did with LN2 trying to find how to bench.....Though the frequency is a bit low but I benched at that frequency just to compare with my other setups.....

ASUS Blitz Formula and CellShock PC14400 DDR3 seems to be VERY fast on ALL benchmarks....

A 2k5 one.....



2k5 COMPARE URL...

Aquamark3 @ 5302MHz and VGA @ 972MHz and 1242MHz....



....when the LN2 started to end, I did a Super-Pi 32M at 5407MHz and it did 9.10min.....BUT I could't save it coz I had no more LN2 to fill the container and I lost it....When it showed the score, and I made my moves to open cpu-z, etc. the temp was too high and the rig rebooted....

I'll try it some other time....

Got PM?

Such killer system perf...these new platforms look like so much fun.

Indeed! Great scores, as always, George!

Thanks!

[hipro5]

Thanks guys......Yes this comb. IS fast indeed.....

[hersounds]

impressive hipro!

[dinos22]

very fast

[hipro5]

Thanks guys.....

I think that working the Super-Pi 32M on this comb. it will be easy to take down a WR at ONLY 5500MHz - 5550MHz....

[hersounds]

you're close,very close to do it hipro

[saaya]

go george go

[hipro5]

With only one VGA on board, this mobo (ASUS Blitz Extreme) can't be touched easy with any other mobo out there......No1 for me....TOO God dumn fast.....NOT only as for Super-Pi BUT as of EVERYTHING....Gee, I'm happy....

Amazing George !, congratulations not only for the tests and tweaking provided in this thread, but also for your 23/09/07 Aquamark & 3D Mark 05 results ... (sorry for the off topic guyzzz)

[hipro5]

Thanks George....

How's that WinRAR Bench at only 3500MHz?.....

[PanteraGSTK]

You're making ddr3 look better and better...Too bad we can't get the blitz boards in the US...Not that I have the money for one anyway...

[Movieman]

I found it funny that George is the first to do some harm to DDR3 sticks.
Your one of a kind!

Hahahaha you don't say !

[BenchZowner]

I found it funny that George is the first to do some harm to DDR3 sticks.

Typically that's wrong, ask my ex DDR3-1600CL7 kit ( that did very well ) what happened to them [ harmed in transportation ]

[hipro5]

Some more testing before benching.....

A newer WinRAR bench.....



...and a 2k6 with SINGLE VGA at low clocks (just testing the mobo for now)....

That's for now.....I'll be back for more....

Looking at those 06' cpu scores it would seem that ddr3 gives an extra boost to the cpu score. I couldn't find a 5200mhz quad cpu score to compare it to (wonder why ), but it does give a 100pt higher cpu score than Vince's striker at higher clocks. http://service.futuremark.com/compare?3dm06=2856930

Ok, I found a better cpu score to compare. This is done by Kinc 45nm cpu @ 5200 on x38 & ddr2 http://service.futuremark.com/compare?3dm06=3171117

No doubt we 're talking about a great cpu score, however carried out with a Yorkfield instead of a Kentsfield used in George's bench ... And the X38 chipset ---> 620FSB without Vcore & Vdimm mods ... I know that in overclocking you can't blame anyone that has better scores with a different setup but, never mind ... Anyway, George nice mobo, is it moded btw ?
