DDR2 testing

[FUGGER]

Playing with DDR2 more and here is what I have come up with.

Centon DDR2 w/ Micron TinyBGA

Centon DDR400 3-2-2-4 400Mhz 1:1 is faster than

BH 5 2-2-2-5 400Mhz 1:1 I875

Corsair 667 4-5-5-15 3:4

Corsair will not do tight timing at all, at least the ones I have dont. The extra 133Mhz does not make up for the slack timing.

The Corsair does not like lots of voltage and errors start around 2.2v

Sample Micron will not do tight timing.

Centon tops out around 240FSB with tight timing. Top end 1:1 290FSB, top end with 3:4 is 270 @ 720Mhz 2.6v

I am yet to find the top end of the Corsair.

Tests done on a DFI 925X-T2 in dire need of bios update

3.4EE ES @ 4.350 stock voltage

Switching over to Asus P5AD2 925X

Sandra's in @ stock then OC'd. Gonna use 3:4 for Corsair to keep it fair :rolleyes:

[FUGGER]

Corsair first

533:3:4 4-4-4-12 1T

[FUGGER]

Buffered

[FUGGER]

Buffered Centon

[FUGGER]

Unbuffered Centon, timings are everything when it comes to DDR2. Ill swap out to the Asus board and try again as it has a 2:3 divider.

[FUGGER]

Oops, just noticed I ran at 3-2-2-5

[althes]

very nice scores, so right now centon is the one to get.

[FUGGER]

I will be doing more memory testing, tight timing pays off bigtime with DDR2. I need to test some OCZ and some Kingston to find out if they can do tight timing.

I will be posting scores from the Asus tomorrow.

[Kanavit]

wow, those Centon ram has some good timings for DDR2! if i go LGA 775 , i will be lookin for those.

[Kalway]

So DDR2 can do x-2-2? Awesome! That means DDR2 will have a chance soon.

[pik-ard v1.1]

ya.... but its doing x-2-2 at 200mhz... im pretty sure thats still 400mhz total(or do we x4 it now? no... that cant be?)

[LilGator]

Actually, I think it's 100MHz x 4 now :p:

Too confusing...

[Soulburner]

That is correct, DDR2-400 would be 100x4.

[pik-ard v1.1]

so its still 400mhz... with the same bandwidth of pc3200 at 3-2-2-<whatever it was>?

doesnt seem so impresive, unless it can keep those timings at higher mhz.

[Wrench]

Hmmm DDR2 is Rambus all over again.

[skate2snow]

FUGGER, We are overclocking here;). For me, stock meens nothing since RAM's can do way much more then stock....

[pik-ard v1.1]

actually, the centon was at stock, the otherone was underclocked... >_>

wrench, i think its to early to say if its going to be rambus revisited. ;)

[FUGGER]

Ill be back benching tomorrow, went down to X games in LA. Got side tracked.

[FUGGER]

I reached the DDR667 speed by using the 3:4 ratio at 250 FSB and popped ran a sandra.

[FUGGER]

Here is a software PLL "AIBooster" and a CPUID

[FUGGER]

Not bad multimedia score

[FUGGER]

Sandra CPU

[FUGGER]

Pi @ 4.255Ghz. I wish I had a PCIe video card.

Here is an aquamark3 link running at these settings.

[FUGGER]

Buffered Sandra

[althes]

I thought you had a pcx5300

[althes]

Those are some nice scores.
How far can you get with the asus board.
Also did you really hit 380fsb with the dfi 925x board.

[FUGGER]

360Mhz on the DDR2 with the 3:4 ratio @ 270FSB slack timing with the Centon. I will find the top end of the corsair. It should be much higher.

Trying for 300FSB DDR800 now on the Asus. My multiples are not working on the Asus and swapping out to the 2.8e

Im kinda picky, I want to post screen shots that are stable w/benches before moving on.

[althes]

understood.I am going to be testing the albatron 915P board tomorrow.
I need to get another cpu.I dont want to kill the one I am using for testing.
Will test it with the albatron pcx5300.

[bias_hjorth]

sligthly offtopic but isnt the Spi run a bit slow is is just me?

[FUGGER]

Its about right since the ram is running at stock speed.

[El.Padrino]

Hello! I have been playing around with my new system and this is what I came up with in the end.

http://www.geocities.com/mxvelocty/DDR2_4-3-3-10_346-2.JPG

I lose my SATA drives if I go any higher FSB. Trying to get an answer from ABIT about it. Using the AA8 Duramax board with a retail 2.8E.

[eva2000]

very nice stuff .. 3.4EE LGA775 :cool:

[FUGGER]

El.Padrino Welcome to XS!

You have exceeded geocities bandwidth allowance =(

You can attach the image with the "post reply" button.

Thanks EVA2000, I will be on EM64T soon. Just a little something to hold me over untill. If you have some database tests let me know.

[El.Padrino]

Attached screen shot. Time to get another place to host pics.

[FUGGER]

2K1 at 4.43Ghz, I still cannot submit scores for 2K1 and 2K3 on LGA775

Sandra resets back to zero after 4.3Ghz, no sandra because I lost control of multiples in beta bios 52

Ownage for a 5700 class video card with no OC.

[eva2000]

woah nice :)

does this mean ya have a 3.4EE ES lying dormant ? :D

[FUGGER]

I just got back my P4C800 from RMA and my S478 3.4EE ES is about to get more abuse. The last mobo started to fall off and eventually died a horrid death when it blasted a moset off the board.

I have a 6800U to torture with it. I will post screen caps of both X800XT and 6800U at top end to show the image quality :D

:eek: how far did it fly ? :D

[FUGGER]

I never found the part

Pulling up to 4.5Ghz now, DDR700. Benchmarkable at that speed. I wish my multiples worked!

[althes]

fugger you go boy.

[althes]

I got ya beat with the with my 5750.

[FUGGER]

Dont make me OC this thing!

What score did you end up with?

[althes]

15k

That a real 5750 or a slower card like a 5350? Seems low to me for a 5700 series card.

[FUGGER]

Still set to quality with no OC.

Downloading rivatuner now...

[Bennah]

So it was a 5750, that seems a good score now...

[althes]

Oh crap what did I start now.

[Bennah]

lol, hes going for your 15K I bet ;)

[pik-ard v1.1]

to bad the 2k1 orb doesnt allow you to select fx5750 :(

[FUGGER]

Shut down and going home, rivatuner loaded.

Default clocks 425/500

[althes]

This should be fun.Cant wait to see how far he gets hahahaahaha

[althes]

any scores yet fuger

[Kalway]

Is it just me, or are these DDR2 numbers getting less and less impressive?

2.9gb/s at 333 mhz?

Cmon Fugger, I want to see something impressive. Not something even my AXP can beat.

[althes]

hahahaha.
ddr2 is not yet ready, the chipsets are not ready yet either.

[FUGGER]

My Asus board is bugged to hell and back after last bios update. I still dont have multipliers and a very long pause to start apps when the machine boots.

Gonna switch back to DFI where I have a sweet 2.5v to feed the DDR2

Kalway, more ram inbound for testing. two manufacturers confirmed DDR800 parts will be ready soon.

[Kalway]

I wanna see some bandwidth on par with regular DDR. 400mhz 3-2-2-8 should be at least 3gb/sec

460mhz should be at least 3.5gb/sec

[FUGGER]

DDR766 news

http://www.ocztechnology.com/aboutocz/news/10

Kalway, DDR400 @ 3-2-2-4

Find me a higher score on regular DDR @ 200FSB?

[Schneider]

I can but it might take some time. the score was like 3400MB/s @ 200FSB. Thugsrook usin a 2.4B 1GB HyperX PC3000 with like Street racer 2225 etc.

edit: nvm.....that pic is lon gone.....:(

[Kalway]

Unbuffered I assume. Find someone with an A64 to do it. I only have an AXP right now. I've neglected to upgrade due to my car :P

I get about half that unbuffered with my KT880, though.
