I managed to grab the last 4 out of 5 sticks of Yeahdone.com.au's stock of some 512MB Hynix PC3200 cas 2.5 listed memory. This memory's chips are the Hynix D43 rated at 200mhz 3-3-3-8 at 2.5v which you can see below

Single channel/stick

on Epox 4PCA3+ rev 1.1

Individually 1 stick can do

@233mhz 2.5-4-3-7 at 2.6v bios (2.55v real idle)
@250mhz 2.5-4-3-7 at 2.6v bios (2.55v real idle)
@260mhz 2.5-4-3-7 at 2.7v bios (2.67-2.68v real idel)
@265mhz 2.5-4-4-7 at 2.7v bios
@270mhz 2.5-4-4-7 at 2.8v bios ( at 2.7v bios had 2 errors 1st Pass of test #5 so upped vdimm by 0.1v )
@275mhz 2.5-4-4-7 at 2.8v
@280mhz 2.5-4-4-7 FAILED at 3.0+v (at 2.8v had 20 errors in 1st pass of test #5 and at 2.9v had 8 errors after 47th pass) in test #4 pc reboots

Dual channel
For first 2 sticks tested on Epox 4PCA3+ rev 1.1:

1. in dual channel max fsb drop from 275mhz to 265-270mhz and i needed 0.1-0.18v more vdimm

2. I can't run Intel Fast enabled like i can with my 2x 256MB ADATA PC4000 while in dual channel @275mhz at 3.2v

3. probably using 512MB sticks reduced oc'ing head room compared to 256MB ADATA PC4000

4. in single channel 1x 512MB Hynix PC3200 like 1x 512MB OCZ PC4000 Gold both @280mhz at 3.3v rebooted themselves in memtest86 around test #4/5 while 1x 256MB ADATA @281mhz manages to run memtest as well as run a few benchies in windows at 3.3v

5. Testing 2 sticks on 4PCA3+ rev 1.1 with latest bios and 2 sticks on PX865PE PRO2 with 1.02 beta bios i noticed something strange in memtest86 reported bandwidth, 4PCA3+ takes the lead in single channel bandwith up to 260mhz 2.5-4-3-7 but >260 PX865PE PRO2's memtest86 bandwidth is higher than 4PCA3+ when even at 2.5-4-4-7.

Prime95 23.6 Bench

Sandra CPU = 9970 / ( 2811/6283 )
Sandra CPU Multimedia = 15008 / 22760

Reasons why OCZ PC4000 Gold run faster and oc higher

1. these Hynix are pc3200 rated memory at 3-3-3-8 at 2.5v
2. these are unmatched sticks and not dual channel hand picked and tested memory
3. Hynix pc3200 ICs haven't been sanded down for better thermal performance like OCZ PC4000
4. 512MB Hynix PC3200 only cost equivalent of AUD$142.50/stick can't expect much for that ? or can you ?
5. different board different performance and interaction with the memory

Still nice for @250mhz speeds at
- 2/3rds cost of 1GB ADATA PC4000
- 1/3rd the cost of 1GB OCZ PC4000 Gold (of which i'll be testing and benching as well thanks to Xcalibur - will pit them against ADATA PC4000, and these Hynix PC3200)

As to those that will fill my pms with where to buy.. i only know of 2 places in Australia and have no idea where in USA etc
1. yeahdone.com.au - they sold out and aren't getting any new stock in for a while as i asked already
2. umart.com.au brisbane has hynix pc3200 listed but not sure if it's the D43 3-3-3-8 at 2.5v sticks of 43 chips with 3-4-4-8 at 2.5v

Damn nice deal, too bad it seems only to be in Asia/Aussie.

Just wondering, what were the Sandra BUFF/Un-BUFF scores when running Dual-Channel @ 270MHz ? Or whatever the highest while in Dual-Channel.

It seems Corsair really likes these chips as well. As the same chips (Hynix 4.3ns) are used in their XMS4000 and TwinX4000 memory. This means that Corsair memory using these chips is not true DDR500, although as your tests show, it's more then capable of overclocking past 250MHz.

eva2000 - Nice review.

I think part of the reason they're hard to find in the US is because of the legal problems with the Dept of Commerce. You can read more about it HERE.

for sandra buff/unbuff click on the link to see the screenshot of speed and timings ;)

the hynix D43 are also apparently on Transcend PC3200 memory too.. so maybe if you're lucky
