Excellent info

and you can use babelfish.altavista.com for translation..

**adad** · 06-02-2003, 06:31 PM

Turtles, human bones, deaf picks, abdomens, sacrificial melons - ah, another one of those damn babelfish chinese translations.

Translation from Chinese to English on Babelfish is hopeless - I think many will agree. Chinese is simply too complex a language to be directly translated [has anyone ever seen a translation where the word prostitute keeps popping out? LOL]

Anyway, I have benefited much from XS so far, and now's the time I make myself useful.

I'll translate the first post for you guys and put babelfish out of its misery.

Here goes.

PUSHING Transcend's DDR400 to DDR540

After seeing Kuang Ta's [some other guy] DDR 501 score benched at CL2.5, I plan to buy a Transcend DDR400 Winbond and try out my luck but no such fortune in TaiZhong [literally Middle Taiwan - actually a city]. I can't find the Winbond BH-5 DDR400 512MB made by Transcend. However I found the CH-5 version. Just when I was about to give up, I spotted the Hynix version of Transcend's DDR400 512MB.

So I thought why not give it a go, since the shopkeeper told me I can exchange it as long as there are no external/surface damage to the chip - and I still have the CH-5 to resort to if all else fails.

The result - DDR510@2.75V, DDR540@2.85V. And I can't push it further because my 2.4C just refuse to break 275 fsb [ed: sounds familiar?] Even if I upped the Vcore to 1.65V I still can't boot - so there.

I also need help to post a picture so any help is appreciated - I'll send the pictures to you.

My testing setup:
P4 2.4C made in 4th April, but think I got lucky and landed a good one

RAM Transcend DDR400 512MB DC Hynix [double-sided], code HY5DU56822BT-D43

Mobo Asus P4P800 non-deluxe

BIOS ver. 1005

All testing done with Performance Mode in BIOS set to Trubo

Ram is SPD enabled

Memory Acceleration Mode set as enabled.

Scores:

DDR 510 single channel Sandra2003SP1 - 3751/3746
DDR 510 single channel Sandra2003SP1 - 5740/5746

DDR 540 single channel Sandra2003SP1 - 3977/3973
DDR 540 single channel Sandra2003SP1 - 6067/6013

[ed: the scores above doesn't make sense to me - I think what he meant was the second and fourth scores are dual-channel - sounds about right to me]

There. Job done.

Anyone who needs translation from time to time may PM me - will be glad to help out - no novels or essays please - critical information, article summaries are ok.

Hmmm....
Guess that smacks around the current sticks available, right Ryan?

**GVCryan** · 06-02-2003, 08:44 PM

Thats around the same timings as the OCZ gold, and they perform nearly identical. Problem is finding Transcend memory in the US. At least you can get OCZ and their excellent warranties here.

**Maelstorm** · 06-02-2003, 09:59 PM

Good stuff! Thank you for translating the article Adad!

**saaya** · 06-03-2003, 02:51 AM

i just hope my twinmos 4.3ns chips get there too

**Rio71** · 08-10-2003, 10:06 AM

hey oc'er, check out this, ddr562 in dual-config.

**Colin** · 08-10-2003, 10:12 AM

That's the same DRAM my TwinX4000 uses...

**saaya** · 08-10-2003, 10:41 AM

thx adad for the translation.

270 with cl3 is nothing special, but with only 2.75v? nice!

that pic was single channel 287mhz.. not dual channel

here's my single channel with ADATA PC4000 same chips with 4PCA3+

**eva2000** · 08-10-2003, 10:51 AM

And ADATA PC4000 @270mhz 3-4-4-8 at 2.85v on Albatron PX865PE PRO2

guess these hynix chips are nice

**saaya** · 08-10-2003, 11:48 AM

does more voltage raise the max cl2 speed, or can it only run fast with cl3 no matter thw volts?

**eva2000** · 08-10-2003, 12:35 PM

certainly more vdimm does raise max speed and stuff but cas2 is something i haven't played with yet.. here's 2x 256MB ADATA PC4000 @ 275mhz 2.5-4-4-7 at 3.2v http://www.xtremesystems.org/forums/...227#post198227

**althes** · 08-10-2003, 01:36 PM

Wonder where I can get some.

**saaya** · 08-10-2003, 01:38 PM

if it clocks like the ocz 4000 you should get at least 255 with cl2 eva.

why havent you tried cl2? i always start with cl2 and see how high i can get...

**[SLC]Tachyon** · 08-10-2003, 03:07 PM

I am trying to hunt down some of this Transcend/Hynix 4.3ns stuff- Transcend does have an online store- (256MB & 512MB PC-3200 sticks are available)- but theres no info to determine what chips they're using currently.

Doing a search for the 256/512MB DDR400 part numbers seems to indicate that there's Transcend PC-3200 out there with Mosel, Samsung, Winbond, and now Hynix chips.

**DDTUNG** · 08-10-2003, 03:35 PM

You guys can also try to get the ADATA DDR500 256MB sticks of which I have two. They are rated at 250MHZ with 3-4-4-8 timings at 2.5V. I can get them to run at 280 DC on the P4C800 with 2.85V. Buffered Sandra scores of 6521/6438. Tighter timings will only hold in the 220s. As explained in great detail by MS at lostcircuits, tRCD is the critical timing here, not CAS.

yeah i'm tracking down some Hynix and Mosel PC3200 and asking the retailer for the chip part numbers for Hynix relating to the ones in Hynix PDF i uploaded at http://www.fileshosts.com/memory/hynix/docs/DDR.pdf

Very useful doc.

Hopefully Transcend will send me a reply tomorrow, if their stuff is sporting the Hynix chips we'll have ourselves a place to buy it in the US.

maybe get some transcend as well?

not sure what chips they've got on them though and you can try yeahdone.com.au for hynix pc3200 I think

already emailed them yesterday waiting for a reply

**AndrOvr** · 08-11-2003, 06:28 PM

Well.. Ive got some A-Data DDR500 Upto 278.XMhz cas 2.5 6 4 3 w 2.9v in the Epox 4PDA2+ Stable!
Its limited by CPU... I think this mem is capable of ddr600

P.S: Macci.. Package sent to you

(you know what Im talking ritE?.. Send me a SMS when u get it.)
