2-2-2-5 Dual Channel 1GB Modules?

[Philippine Mango]

I'm looking for the best modules that will if it's possible, run 2-2-2-5 timings at DDR500 Speeds at 2.8V. My motherboard only supports 2.8V/2.75 for memory voltage and I want to know if I can get DDR500 memory that will run at 2-2-2-5 or something quite fast at most 2.8V. I've noticed that the 2-2-2-5 memory out there that runs at that timings at DDR500, require 3.3v which is not possible on my board.

You'd be hard pressed to find those timing available @ 2.8v and they would be cherry picked sticks demanding high dollars so I would suggest this Method

Get the OCZ DDR Booster.

LED, I see that it's not possible to get modules like that, so what would be the very best timings I could get at 2.8V running atleast 250DDR?

Prolly the OCZ's and I think they just came out with PC4000's or Corsairs as they are pretested 3rd party chips...I use Ballistix which come in many flavors...

Edit=I found a review on the new OCZ's

My Ballistix

Bah This is confusing me and pissing me off :|.... For example on anand's test on the P4 Platform, he scores much less than me at the SAME FSB speeds with significantly better timings...
Anand's Review on Corsair 4400C25
On the Buffered Tests at 250MHZ FSB 2-3-3-5, he scores: INT 5567 FLT 5561
On My Buffered tests at 250MHZ FSB 3-4-4-8, I score: INT 5851 FLT 5857

For the Super Pi Tests, at 250MHZ FSB 2-3-3-5, he scores: 104secs
For the Super Pi Tests, at 250MHZ FSB 3-4-4-8, I score: 96secs

My system specs are in "My Rigs" under the system "abit". I'm using Corsair TwinX PC4000 Dual Channel Modules which are CIRCA 2003 (just found out which is disappointing because I bought them in '04).

Now this would seem like good news because my system is performing better than systems equipped with better memory but the thing is, I do not know if upgrading my system with 4 of these 512MB modules in the anand review or modules from other brands would be such a good idea or not.

He has a 2,4C whereas the rig in your signature is a 2.8C

So its 3Ghz vs 3.5Ghz; your Super Pi should be a lot faster and latency has nothing to do with bandwidth.

Thise Sandra tests are synthetic benches and I doubt if you would really notice a massive difference in real time so i would suggest just trying to match up your current RAM or even passing as DDR2 is right around the corner...

How can one measure the performance of lantecy then?

Here you go: "The three 2GB kits that we tested are all winners, but the OCZ PC4000 EB Platinum Edition stood out from the crowd. The OCZ performed at fast 2-3-2 memory timings at DDR400 to 3-3-2 at DDR550 and never required more than 2.7V to maintain complete stability in our memory testing. It is rare to find a memory with this wide range of performance that is perfectly happy with voltages available on most any motherboard that you can buy. In fact, the OCZ 1 GB modules do not seem to really like voltages beyond about 2.8V."

So if ANYTHING will do it, it will be these.

Heh, your back, dunno when you came back. Thing is, while I already know about that ram and I definately considered it, the reason why I didn't stick with it is because I've got a socket 478 based system (Abit-IC7-G) which is the 875P chipset. I was thinking of just getting 4X512MB sticks because I'd assume that I'd be able to get modules that could run at tighter timings than with 1GB modules.

 

[ribbon13]

well this would give you super tight timings at lower speeds and will meet voltage needs, but it's an expensive solution.

isn't plat rev. II 2-2-2-5?

While it IS, it's likely IIRC to require large amounts of voltage to achieve those timings at DDR500.
