Corsair TwinX1024-4000 PRO: Improving DDR500 Performanceby Wesley Fink on September 15, 2003 10:36 PM EST

Today, Corsair officially introduces the PRO series of XMS memory. All of the new PRO series modules feature a new cast aluminum heatsink and flashing LED “activity lights”. According to Corsair, the following modules will be immediately available:
- TwinX1024-4000PRO — matched pair of 512MB, DDR500 modules
- TwinX1024-3200C2PRO — matched pair of 512MB, DDR400 modules
- CMX512-4000PRO — 512MB, DDR500 module
- CMX512-3200C2PRO — 512MB, DDR400 module
As you can see, the Pro modules are taller, at 1.75" than regular XMS memory. This is most likely to allow room for the LED array that shows memory activity. The cast aluminum heatsink has fins that Corsair claims increases surface area by 95% compared to standard aluminum ramsinks, which should increase the cooling ability. There are also 18 LED’s in 3 different colors — green, yellow, red — which show the level of memory activity.
Certainly, the new flashing LED’s will give another option to case modding. Those who prefer side windows and an attention-grabbing appearance will welcome the activity LED’s. The flashing 3-color display puts on quite a show compared to the more conventional memory designs.
Corsair tests the DDR500 modules in an Asus P4C800 motherboard and the modules are programmed to JEDEC 3200 (DDR400) values There is no official standard yet for DDR500, but all of the manufacturers seem to be using the 875/865 chipset motherboards to verify their high-speed performance. There is frankly no real need for DDR500 on the current fastest Athlon chipsets, since neither the chipsets nor the Athlon CPUs have shown any capability of reaching DDR500 performance levels. While this may change with the introduction of Athlon64, the DDR500 and high-speed memory phenomenon is, for now, an Intel chipset playground — primarily related to the Intel 875/865 chipsets.
With the TwinX1024-3200C2PRO, Corsair tests performance in both an Asus A7N8X nForce2 Ultra 400 board and the P4C800 Intel 875 motherboard. This looks very sensible since Athlon fans will more likely need DDR400 to DDR433 memory for best performance.

PAT disabled, Fast or Turbo?

dakost - Sunday, October 5, 2003 - linkThese reviews should include the Twinmos Twister PC4000. This is reported to be able to do 2-2-3-6 at ddr400 at 2.75V and 2.5-3-3-6 (the only memory i have seen at 3-3 as ddr500) at ddr500 at 2.85V with the highest oc's at ddr530 at 2.5-3-3-8 at 2.85V.

DragonReborn - Thursday, September 18, 2003 - linkI'm a little on the fence here. I have a watercooled setup with an IS7/2.4c combo and I was wondering what the best 2x 512 sticks of ram would be without killing the bank. I want to do some OC'ing so I was thinking of getting the Geil 4000 plat or Buffalo 3700 (BH-5 chips). Any reason to get another kind or not to get one of the ones I mentioned?? Thanks!

all these comments seems pretty self promoting from ocz and geil... let the readers decide and choose.
Anonymous User - Thursday, September 18, 2003 - linkyes, but it is Geil platinium used in the test, that doesn't use WLCSP. and still the Golden Dragon series is good althernative for reducing the heat inside the case. And don't forget that Geil's Golden series last the first ddr500 modules back in March http://www.xbitlabs.com/news/memory/display/200303... though they didn't get available recently.
Anonymous User - Wednesday, September 17, 2003 - linkBut Geil's memory OCed pretty nicely here - at least the sample Wes had did.
Anonymous User - Wednesday, September 17, 2003 - linkWLCSP is intended as a thermal solution and to date hasn't shown much promise in the enthusiast sector as it doesn't OC as well as TSOP's.
Elite9 - Wednesday, September 17, 2003 - linkWhy is nobody but Geil using WLCSP packaging on their DIMMS? I've seen it in notebooks, but it seems to be a great option for high-speed DRAM.
