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

[PanteraGSTK]

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 ?

I understand that. Yorkfield is supposed to be better, as is x38. The point I'm trying to make is ddr3 has an impact on cpu score compared to ddr2. If I could find a p35 kentsfield cpu score at 5200mhz I would post it. As you can see it is a hard thing to find. It's kinda hard comparing something only a few people are able to accomplish...

What I need is a kentsfield running at 3.6ghz on a p35 board with ddr3. Then, the same cpu @ 3.6ghz and a p35 board, but with ddr2. We'd be able to tell.

Thanks guys........
Yes the mobo IS moded as shown in previus page of this thread with a link...

3.6GHz has ALWAYS been my "reference" frequency......I have a LOT of benches at 3.6GHz PLUS I could test P35 with DDR2 and DDR3 (Blitz Extreme and Blitz Formula)......
ALSO CPU score is NOT only "ram depentand" (except the CPU of course).....It depends on some more things....EVEN of the VGA and "how" you "play" with it....

Interesting. It just seems that the ddr3 cpu scores are higher. If I had the parts I'd find out for myself. If you could test with the only variable being ddr2/ddr3 I'd appreciate it, plus I could stop obsessing about it...

[George_o/c]

...plus I could stop obsessing about it...

Showing some interest for specific pc components (Rams in your case) is not obsession ... It's an overclocker's duty !
George could you publish some results in between ddr2 and ddr3 at the "reference" cpu speed ? Could be useful ...

@hipro5...... have you done any testing with P35 on the Ram I have without jacking the Go>Go Juice way up? If so do have any suggestions on subs I know this is far fetched for you but do you have some not such Xtreem Examples to go off of? Sorry bro but I'm a little out of the league you play in

[railmeat]

Thanks for this nice comparison!
But I still think that DDR3 isn't worth the extra cash for me at the moment. However, I'm very pleased with how the first generation of DDR3 performs!

"But I still think that DDR3 isn't worth the extra cash"

totally agree:difference is slim at best,nice review.ddr3 can wait another year or so,ddr2 market is a steal now..

[hipro5]

DDR3 vs DDR2 vs price vs performance.......Hmmmm......You guys may have right about the prices BUT as for me (and some others too), I want to get the max I can with whatever I can.....If you want an average/top rams, yes go to DDR2....BUT if you want the MAX, then the only way is the DDR3.....

@ Brother Esau: Write down how exactly whould you like to see DDR3 (frequency/valtage/etc) and I'll do it for you to compare.....

@ George_o/c: Yes I will do....

@ PanteraGSTK: Yes I'll do it too M8....

Great. It will be interesting to see the results.

[George_o/c]

Thanks for being willing to fulfill our requests George, waiting patiently the results

[SuperMiguel]

so if im getting the asus maximus should i go with the extreme or the formula?? also any ETA on the maximus for USA

[saaya]

1 month i think?

[The Stilt]

I´m currently testing Asus P5E3 Deluxe.
The board can easily do 2000MHz DRAM frequency but it seem to be super picky on the MCH & DRAM voltage.

For example 1.63V doesn´t boot, 1.65V works fine, 1.69V doesn´t boot, 1.71V gives errors, 1.73V works fine...

Same goes for DRAM voltage.

The vcore is messed up too.
It is usually 0.05V lower than the bios setting..

[saaya]

hmmm thanks for the input roger!
did you meassure the voltages?
i hope its just a bios problem and not a problem of the voltages being applied but not being stable.

[hipro5]

I just got ASUS P5BE3 WS Pro......X38 DDR3.....AND VCore Pre-Moded up to 2.3VCore.....I'll test that too.....


Now......Some updates under LN2.....

I MUST confess that this ASUS Blitz Extreme is VERY easy mobo for overclocking.....I had to feel that relaxed, LONG - LONG time ago.....

The CPU is a QX6850 working ALL 4 Cores of it....

I'm running it at ONLY 5408MHz for "reference" for my other benchies which were done with other mobos......
To be honnest, I have tested it to find how high it can go BUT I WILL NOT POST IT YET....
Its MAX benching frequency will be posted at 20-21 of October at our Overclocking Event here in Hellas.....among us will be k|ngp|n and Shamino...
Well these guys will be the FIRST ones to see how HIGH this CPU can go, coz we will bench with it those days.....
A tip: at 5407MHz it's TOO EASY to bench it....

Now nough talking - let's go - .....

ALL benchies were run with CellShock PC14400 DDR3 Ram Modules at 2.35Vdimm powered by a DDR Maximizer and a 1200Watts hipro-tech PSU...

Super-Pi 32M at 5408MHz.....





Aquamark3 with ASUS HD2900XT CrossFire ON AIR 880/990.....at ONLY 5302MHz (I did this while starting to test the CPU and then I forgot to run it at 5408MHz).....



3DMark2003 with SINGLE XFX 8800Ultra at ONLY 972/1242 under LN2....








COMPARE 2k3 URL...


3DMark2005 with ASUS HD2900XT CrossFire ON AIR 880/990.....






COMPARE 2k5 URL...


Well that's for now.....I'll be back real soon with some more benches BUT AT ONLY 5408MHz.....

Really impressive George ... And the QX6850 you got there, is quite amazing (5400MHz - 4 cores enabled ) ... As far as the 3D Mark results are concerned, congrats too, 35000 marks with 2900XT in Crossfire mode :o Some more global awards added in your profile ! Very nice work George, Hellas Overclocking Team is pleased for one more time ...

Thanks a lot M8 for your kind words.....

BUT I assure you that these are ONLY peanuts in front of what this chip is capable of...

[George_o/c]

I am really curious about the cpu frequency you have achieved ... Waiting for the event to be carried out ... What can I say about the Blitz ? I have only o/ced some C2Ds ( E4400, E6320, E6420) under water with a modded P5K Deluxe, never had the chance to play with a Blitz Extreme

[saaya]

i cant wait

[Brother Esau]

What happened George I never heard from you

[hipro5]

What happened George I never heard from you

For what?....

[Brother Esau]

For what?....

Didn't you get my PM?

[Oliver]

i cant wait

I cant wait to.

That is a really sweet qx6850 you have there .
