The memory controllers on the CPU cannot clock 4 sticks of Ram at DDR400 and a 1T command rate. The new Venice/San Diego CPU's will run them at DDR400 but still at 2T. If you want 2GB, I would recommend a 2GB kit that has 2 x 1 GB sticks...you will be able to run at DDR400 (or higher with some OC) and at 1T which will give you better performance.

Answering your first question, no I do not recommend mixing stick models ever, the chips on the sticks are different 95% of the time and each like different timings, voltages, Drive Strengths, etc that prevent them from working smoothly together. This is not always 100% true but as a general rule, we do not recommend it.

I hope that helps

I am planning to buy 2 BFG 6800gt's to go with my Asus A8N-SLI Deluxe setup and I am just wondering if my 520W Modstream powersupply will be able to power the setup.The setup will also include Athlon FX-55,1 GB OCZ pc3200 plat. ed.,1 sata HD,1 DVD-RW,1 floppy,Creative Audigy 2,and 5 fans including the heatsink fan.Any tips on setup would be greatly appreciated,hopefully it will work. *crosses his fingers*

Hi ToP3koms,

You can use the calculator here to give you an Idea of your power requirements: http://extreme.outervision.com

You are going to be "tight" with that setup and the Modstream the Powerstream 520 and/or 600 have more amperage available on the 12V rail which is where the heaviest usage would be.

Check out the calculator to see what you come up with, you can also punch in any overclock you plan on now

ToP3koms · May 13, 2005, 04:39 AM

I came out just under 500W without any overclock ,which I don't really plan on anyway,so hopefully it will workout ok.The cards are on their way so we'll see.Thank you for your time Ryder.

Lowfat · May 13, 2005, 11:24 AM

wow thanks for the link. that is by far the best power calculator i've seen.

ToP3koms · May 21, 2005, 03:13 PM

It is working Ryder ,the 520w modstream is apparently upto the task.My 12V rail is riding a little low (11.6V through Asus probe) but it was at 11.7V with the x850 so I feel confident I even added a 80mm window fan to blow right over the 2 gt's and it is all working out well.Thanks again for your prompt response and the link

*RyderOCZ* · May 23, 2005, 08:59 PM

That's great, thanks for letting me know

Judas · Jun 3, 2005, 06:34 PM

OK, got a few questions that may take a few weeks to answer depending on my availability to respond to any answer or questions.... Sorry for that.

In any case, i recently worked a 92 hour week which has put up enough cash to pay off a few dozen bills and start to getting some major things fixed. ATM, my 350 watt enermax has been overloaded for well over a few dozen months, and like the last 350 watt enermax that i took out, it's starting to fail under the constant presure. (hey, they still work great, the first one still running my dedicated media center server 24/7

)

Anyways, enough babbling, I need a PSU, a damn good one, this leads me directly to OCZ of course. And although i'd like to get the nice and tidy modstream, there are a few "problems" that i would think will be addressed in the next revision, and i also need the extreme power so 520 watts isn't going to do good enough for me, 600 watts will

So that leaves me with the only choice i can see so far, Powerstream 600. However, i'm not quite sure or understand how the v12-1 and v12-2 rails work. What is this and how does it effect everything. (sorry if this has been explained once already, kinda in a hurry atm). Also, I don't want to pry on anyone, or cause any trouble, but should i if i can, wait a little longer for say a revised more powerful modstream?, perhaps wait for a 650 or 700 watt variation of the powerstream? If those questions can't be answered, don't worry, just don't answer them

Meanwhile i'm here still kicking this POS X-Connect....... grr... having a hard time returning this thing (broke down the first month i had it and it's been now nearly 9 months since)

*RyderOCZ* · Jun 3, 2005, 06:40 PM

Hi Judas,

Sorry about the X connect, that is horrible

If you can wait....a more powerful Modstream (600-650 I think) is in the works...ETA, I don't know.

The dual 12V rail works like this.....18A rail is connected through the ATX connector for the mobo...The 20A #2 rail is connected to all the molex / sata / video card connectors for your peripherals.
Pretty simple and I hope that answers your questions

Judas · Jun 3, 2005, 07:45 PM

wow, thanks again. I figured that how the dual 12v rails worked.

However your 520 watt modstream (or powerstream for that matter) doesn't have this...

I plan on getting 2 of these OCZ or possibly 3 all rated the same, highest wattage.

thanks for the very quick reply

*RyderOCZ* · Jun 3, 2005, 08:03 PM

Yes the 600W Powerstream is the only dual rail we offer at the moment. The "new" modstream unit will probably have 2 rails with the option of combining them if you wish. Here is a link to some pics of the "Beta" unit from Cebit. Post #10 has the pics

Ryder, what exactly does the DDR Booster do? From it's description, it "supplies cleaner power" to the memory modules but that doesn't explain much, to me anyhow. Does it "read" the voltage in your RAM slot(s) and then limit it to a stable ammount to prevent fluctuations, or I am missing the point?

Does the DDR Booster always need to remain in a DDR slot during the PC's operation or is it diagnostic-based and therefore is removed after the work is done? Thanks!

*RyderOCZ* · Jun 22, 2005, 09:10 AM

Hi Daedal,

The DDR Booster is used to supply more voltage to your ram than many motherboards will allow at stock.
It comes with a harness that plugs in between the ATX connector from the PSU and the motherboard connector. There are 2 molex connectors that go to the booster and it feeds off the 5V rail of the PSU to supply voltage to the DIMMS. You have to leave it in for it to work and it is not compatible with all motherboards.
There is a POT (Potentiometer) on it that you can adjust the voltage to your DIMMS with and also an LED readout so you know what the voltage is.
Your Power Supply must have a -5V line on it (white wire normally) for the display to work properly.

Did I answer everything?

Hope that helps

mike2h · Jun 22, 2005, 07:16 PM

can you give me recc volt & max volt for - OCZ500512ELDC-K. can not find them at website anymore. just flashed my bios & upgraded cpu so got to start experimenting with oc again

.

*RyderOCZ* · Jun 22, 2005, 10:02 PM

HI Mike,

Recommended voltage would be 2.6-2.7V...Max of 2.9V....normally doesn't help a lot, but it depends on the board/CPU too. Those have Hynix CT-D5 chips on them.

mike2h · Jun 22, 2005, 10:26 PM

thx for the swift response.

arent those the same modules that are in your gold 4400?
unfortunately i do not think i am going to be getting full use out of them this time around. i was using them (4x256) with a 2.4@ 3.03, 1:1, timings at 3-4-4-5. actually had it stable at 258 bus speed with those timings but exceeded my 50c load limit.
now i have a 3.2 prescott that i have running at 3.6 & 2.5-3-3-5 timings. heat is definetly becoming an issue(but not as bad as i thought). i am hoping to get to 235 bus with those timings wich will give me approx 3.8. i figure the slightly slower bus will be more than made up by the tighter timings. it just bugs me that i wll not be able to fully utilise my mem.

do you think those sticks can hold those timings at that speed? i know there are a lot of variables involved, but i would just like a general idea so i am not banging my head against a wall

i am not going to try 235 for another day or so, got to let the new cpu burn-in some more & let the AS cure.

*RyderOCZ* · Jun 23, 2005, 03:52 PM

They are rated at 3-4-4-8 at 250 FSB...so I doubt they will hold 2.5-3-3 at 250...maybe 2.5-4-3 or something like that.

Yup; that does answer all my questions and then some. Thank you.

Hey Ryder,

I recently RMA'd my OCZ modstream 520w. because the fan started rattling. I got (what i think) is a brand new modstream 520w. I was great for a couple weeks, but recently the fan has started to rattle a bit everynow and then. Is this a common problem with modstreams? I don't think im going to RMA this one, but instead just replace the fan eventually. Thanks. I really love this PS and the style (the 1 120mm fan). As far as the rails and stability go, it's flawless.

Warpy · Jul 4, 2005, 10:07 PM

This is great news! I just bought a 2GB KIT of OCZ Platinum PC3200 EL Kit, I am yet to install it as it hasn't arrived just yet.

CDsDontBurn · Jul 4, 2005, 10:12 PM

there's two things i don't like about my OCZ PowerStream PSU. The green fan, and the low RPM/CFM output on the two fans. I don't feel it cools the PSU well enough. Just my two cents

mike2h · Jul 7, 2005, 11:36 PM

well, my new 3.2d is not going to go over 3.45.(i am really dissapointed in this cpu) this is a 217 bus which means my 4x256 of ocz 4000 is being wasted.

i am thinking about buying 2x512 of ram. i want it to be able to run stable 2-2-2-5 at 400 to 420 mhz. which ocz dual channel kit would you rec?

OCZ PC3200 VX GOLD if your motherboard can supply the voltage, or have a DDR booster.

I run 245FSB @ 2-2-2-11 no problems. but it needs 3.3V.

mike2h · Jul 8, 2005, 04:07 AM

thx for the help but i want something that will run at the specs i gave. my current mem can run at 3-4-4-5 at 257 with lower voltage than that.
didnt they have the 3500 vers of that mem available when you made your purchase? has tighter timings & lower volt req at the speed you are running at.

CDsDontBurn · Jul 8, 2005, 03:32 PM

OCZ 3200 Gold 2-2-2-5

. i'm sure it can do 2-2-2-5 timings @ 220FSB running 2.8v. And i'm sure you can get 2.5-3-3-8 @ 250FSB running 2.8v~3.0v easily running the 1:1 ratio
