did u get 2x256MB or 2x512MB ?
I´ve got only one 512MB....
I think this confirmes what I was thinking. I did a review w/ 2x256(so its SS), and w/ a P4, And the bandwidth was not very good too... But I was at 3 on CAS, its doing a little difference in bandwidth(actually enough big that I found....), and to have 2-2(RAS-RAS to CAS), you have to put 3CAS most of the times, so then the band is a bit debalanced becoze the CAS is higher then the RAS related.... But It should still have a better bandwidth....
EB is all about variable read command and keeping trcd and trp tight using cas2.5 or cas3.
SS modules will always perform with less unbufftered bandwidth on the 875 due to the chipset design needing double sided dimms to perform best, on 939 and NF2 this is not the case although nf2 has a cpc issue with 512's or greater spread over 2 ranks.
Got my 3700 EB today (2x 512MB). After some quick benching 270 MHz seems stable. Timings where 3.0-2-2-7 and 3.1V. Didn't try any other timings or voltages.
Guess this result is OK. :)
BigToe. Why OCZ make all 256MB modules SS? is it more expensive to make?
my god those are some insane numbers for eb, anyone know whats my chances of hitting 250 at 3-2-2-8 at 2.9v?
Il think mine did it.Quote:

they should be very good.. allthough some modules like mine :rolleyes: wont go that much further.. It also seems as anything above 3.3vdimm dont do any good.. Been running mine off the 3.3v line (3.3v ---> vdimm mod) which gives me 3.45v - no oc difference at all compared to 3.1v..Quote:

lets see....maybe the OCZ-Booster will bring a special-super-duper-ultra-deluxe-boost especially for OCZ-RAM-sticks :D ;)
then we can reach only with OCZ-RAM >300MHz / 2.5-2-2-5 @ 3.9V :slobber:
....I WANT THAT BOOSTER NOW ! :D
Nah, I noticed that at 3.5V I first dont have a little boost at all, and the RAM's start to be unstable. So I think that at 3.9V the RAM's wont last long....
tried 3.87v for a short time.. ..:slapass: did nothing besides smelling very warm.. :flame:
rofl...ok....but still hoping of the super-ultra-boost for ocz-sticks, like for NV-Cards on NV-MoBos :D ;)
Its ok, We saw your first message;):p:
oops....deleted now :D ;)
My PC3700EB isn't very stable...The max I can do is about 230Mhz 3-2-2-10 (Or 2.5-2-2-10, doesn't make a difference) But after that it isn't stable, not even at 3.2-3.4V The max I did for a bench was 275Mhz 3-2-2-10, but not stable at all. (And using 1 stick, the max with 2 sticks is 260Mhz) The strange thing is that there's quite a big difference between 230Mhz max stable and 275Mhz max...Could it be the cooling of my NB, which is still stock cooled by the little cooler, or do I just have some bad Ram, and should I try to sell it and buy some new PC3700EB...
That sounds a bit strange. I think you should perhaps eliminate the possibility of your MB, and/or maybe adding extra cooling to NB.
My PC-3700 512MB EB can do 265Mhz 3-3-2-8, 2T and yesterday I did some bechmarking 3-2-2-7, 1T 245MHz with only 2.75V...
And now it´s prime 7h stable @230MHz@2.75V@3-2-2-7, 1T.
I also noticed that these sticks tend to get very hot when running prime even with 2.75V so is your case cooling proper?
Yes, the case cooling is ok, I even put a fan on the memory and the room temp was about 20C...I'll do some more testing today, but I think I may just have some bad sticks...
I hoped to run the memory at 250Mhz 1:1 2.5-2-2-10 or 3-2-2-10, but that isn't possible with there, Prime crashes in about 1Min if I run at 250Mhz 1:1 :(
265 MHz 3-2-2-5 is what these sticks do stable with 3.1V. :)
BH-5 sticks would never do this.
weeehhhh, very nice ! :) :slobber:
and "only" 3.1V :)
are u able to try 3.4-3.5V ? (i suppose, your mobo is vmodded)
timings are ok, just more MHz.....oh man, i dream of 300MHz 24/7...doesn't matter what timings :D ;)
No. They don't like the CAS3 cra*p :lol:Quote:

you know, that EB-Cas3 = normal-Cas2 ? ;)
Thanks. I'm very pleased with these sticks. They where expensive, but guess they are worth the money :DQuote:

Yes I could try more voltages, just don't wanna blow these sticks. :)
I think my dream of 300 MHz is only a dream. Have one problem. I can bench 275 MHz, with 3-2-2-7 or 3-2-2-8 (3.1V), but 280 MHz is no go, even with 3-4-4-11. Dunno what the problem is? Have to find out.
hmm....3.5V maybe for me ? :D
just wanted to see....but they're your sticks...;)
want to see, if the rumor of "upper-3.2V-doesn't bring alot @ OCZ-EB-sticks" is true.....
I doubt that (in 3d) - the difference ain't that big, but there's a difference. :DQuote:

3 clock cycles are 3 clock cycles (3=3╪2)... :rolleyes:
