Tony was running our new Plat eb 4200 rev 2 LD at those speeds 1 gb x 2

Does that answer your question ?

What IC's do they use now that the product has been released?

Tras 8 yielded lower bandwidth than 12...I go with what works.

Centon doesn't have anything to match this at the mo...infact no one does as far as I know.

As regards new results I have been hitting DDR733 with 4-2-2-12 timings with some modules, some a little lower, some a little higher ;)

I wasn't to keen on DDR2 at first...now my attitude is changing.

definitely micron I'd say (90%)....they are the only know ddr2 chips which can do 3-2-2-x timings

I'm guessing these are the new DDR2 modules you're talking about:

OCZ PC2-4200EB DDR2 Rev.2 Dual Channel 1GB Kit (OCZ25331024EBDCPER2-K)

OCZ PC2-4200EB DDR2 Rev.2 Dual Channel 2GB Kit (OCZ25332048EBDCPER2-K)

Look at those price tags though:
1GB (2x512MB) - $435
2GB (2x1GB) - $818

OUCH. I'm guessing not too many people are willing to spend that much on RAM, I know I'm not.

Great DDR2 there. OCZ being top notch once again :thumbsup:

Those prices are quite high becuase that the first company to stock them and there trying to make a killing.

Give it a week or 2 till everyone gets them up,

Also DDR 2 is still a premium over DDR 1

New Stuff released like right NOW:

PQI Turbo Series Low Latency DDR2
http://www.pqimemory.com/turbo_memory_ddr2.asp

Yes, the revolution has begun ! (And right when I was trying to put together a 0.09 s939 rig :( )

Well I was going to get back benching but I had a few issues with a PSU which sort of put the breaks on a little.

I can say DDr2 is still expensive to buy due also to lack of demand, as yields improve and demand rises prices will fall.OCZ are really trying to get DDR2 to where we think it should be, these modules do 3-2-2- at DDR600 all day 1.8V infact 667 is pretty easy on 90%+ at 1.8v also, over that cas4 really helped.

As soon as i can i will get the board re set up and run some more benches if i can.

Here's my review...of low latency DDR2 (not the greatest review even in my opinion...[time]) Feel free to comment

http://www.ocprices.com/index.php?re...action=reviews

Wonder if we could get hold of the new OCZ ram... :rolleyes: bigtoe? :D

EDIT: I just killed my ram, I shoved 2.48v into the ram on my AA8 motherboard and it died within about 3 hours of memtesting :(

It did DDR2-720 at 3-2-2-4 timings shortly before its death tho (since the review...I have modded the nb / vdimm voltages so I was able to get MORE than DDR2-706 with the prescott)

4-4-4 = low latency? :stick: ... i dont get why no manufacturer sells memory thats guarantueed to run 3-2-2... i guess they will wait and see how successfull ocz is with their new REAL low latency memory before they get their 4ss moving :P

so micron ddr2 dies at 2.5v... good to know! thx for that valuable info! :toast:
maybe we should make a thread in the memory section collecting voltages at wich hardware died :)

sorry to hear about your loss... :(

don't quote me! might just be my method of modding the AA8 vDimm :cool:

had to play a little more ;) now im using a REAL old PCI Video card as my PCIe has yet to arrive, this is at DDR733 4-2-2-12 2.1Vdimm.

Im sure you guys would squeeze even more from this, back at OCZ the 512modules look like they may do 3-2-2-12 at 733 with a little less voltage so things look even better...we will soon see.

And now for the unbuffered...i have a feeling this may be a world record:) or Sandra is seriously flawed.

flawd ;) ...I hope...I get no where near those scores with ddr2-720 3-2-2-4

ram lookin good..:D

bigtoe, could you explain me, how to calculate the "real" frequency of the RAM?

in the one pic there are:

Frequency: 366,66MHz

FSB: DRAM - 3:4

now, what's the real freq? :confused:

FSB724. 3:4 divider 366.66Mhz Memory Clock. Not sure if this is the 'real real' clock...

FSB is at 275 MHz, so with the mem divider 3:4, the mem freq. will be 366,66MHz. Which also is called 733,33Mhz DDR2

It was 275fsb with the 533ram ratio (3:4) for ddr733. Now i have played with sandra a little more and its reading correct...looks like i will have to see if 6k unbuffered is achievable now ;)

:lol:

It's not you faking results, it's sandra currently not liking the ddr2 dimms ;)

Brutal speed bigtoe :D

what kind of numbers do you get from (OCZ) memtest86+?

Well, it doesn't like 277fsb it seems as after that I get 16mb/s so sandra or the board is at fault. I can tell you all benches at 275 are HUGE...what ever memory bench i run the numbers are massive.
