new winbond ch-5 !

[Lunatic]

hi guys ! the new winbond ch-5 chips seems to rock!
here are the speccs :
Features:
- Chip on board: Winbond W942508CH-5.
- CL 2,5-3-3 (default SPD).
- CL 2-2-2 (tested).
- 400MHz DDR.
- Package: 184-pin DIMM.
- Unbuffered.
- Alimentazione: 2,5V (± 0,3V max).
- Serial Presence Detect (SPD) EEPROM on board.

Winbond BH-5 - 0.175 micron

Winbond CH-5 - 0.13 micron

A-data seems to be the only one with these new chips

here is a thread about it : http://www.amdforums.com/showthread.php?threadid=215281

and you can buy them here http://www.swzonesystem.it/product_i...roducts_id=133

man, do i regret buying these corsair 3500 when i could have gotten these for dirt cheap

i dont know i dont live in italy i just got that link

[T@nker-xXx]

in france you can have a-data CH5
but it's rare

[Lunatic]

if someone have these ch-5 please post results

I got TwinMOS PC3700 2x256MB and seriously have doubts, that those are remarked CH-5.... If not from the highest quality CH-5, but still CH-5....

The reasons:

- dislikes RAS-to-CAS = 2 ( see that japanese screenshot @amdmb ), pretty much the same as the CH-5 and dislike the BH-5....

- hates voltages above 2.8V - just gets worse.... that I give out to the 0.13mm production process....

- Runs high 480s@ 2.7V without a problem on EPoX 4PEA+ MoBo...

Tomorrow I'll get another 8RDA+, that would do 220MHz+ and will test them out....

Yes, please test them out on an AMD system and let us know how they did!

my twinmos PC3700 runs at 250 and 3.2v
no problems

speakin of ships, what kind do i have in my corsair xms pc3200 twinx?

[charlie]

What's the big deal?
My Geil PC3700 and it's 4.5ns chips do ddr504 @ 3.08v.
cas2, 6,3,3. For me to upgrade, I'll need something that'll do about ddr520.

I added two to my shopping cart, but I can't read the stuff to fill it in.

I did see though that they do ship to anywhere, at least any country is selectable from a drop down list. Including United States.

Hmm, my OCZ PC3700 EL seems to dislike tRCD of 2 also. Have only tried on a KD7-S (KT400) and NF7-S v1.2 (nForce2). Yet other users have OCZ EL memory that likes it. Some say it's a chipset issue, others say it's a memory issue.

That's in an Intel rig, though, right? Slightly different than running at that speed in an AMD rig.

same here, i've got PC3700 EL as well.. i thought it was just me

[WildKard]

Im using OCZ 3700el as well, I can run 4-2-2-2 on my friends a7n8x but need to run 5-3-2-2 on my abit nf7s but even MORE WEIRD is I can run 5-2-2-2 using Win2K but only 5-3-2-2 using WinXP with my Asus P4PE

just ask someone in the forums that speaks italian

edit: you could pm spaceboy or diabloII they are italian

Well I'm runnin 440MHz DDR 2.0-4-3-2 2.7V.... the MoBo won't go 230MHz.... will try 225 in some hours

corsair xms3200 = bh-6
corsair xms3500 = bh-5

read the 2nd post down.

damni!! haha, i just bought this corsair xms pc3200 twinx and spent a good $360 on it, and it's already surpassed less than a month later. sheesh! i hope i can still pump my 2400+ to around 2700 mHz or so with it tho

XMS3200 uses BH-6
XMS3200LL (twinx) uses BH-5
XMS3500 uses BH-5

XMS3500 and XMS3200LL uses the same chips

really???

haha , i have dc twinx (2x 512) (XMS3200LL ) yay!!

Yet again this backs up my belief that OCZ uses Winbond.

If Adata handles some of OCZ's manufactturing (which they do), and Adata uses Winbond, and they act identical. Then they are just rebadged modules.

I haven't seen any evidence to the contrary (at least).

I came across this french website's news item last week, might interest you, which I have translated into English via Google:

http://www.hardware.fr/news/lire/22-11-2002/#5366

Following our news preceding, OCZ contacted us for us given more precise details on their new chips memories. In fact, this news memories DDR466 and 500 are based on "die" Winbond DDR500 which are packaged by using a packaging TSOP specific to OCZ, the EL GDR, which is finer and which thus offers a less thermal resistance. Now remain to know if these chips will be more powerful in practice than the future chips 4ns of Winbond, which will use for their part a traditional packaging.

Plus the fact OCZ mentioned they had moved to a 0.13-micron IC process and Winbond are producing these CH-5 that are also 0.13-micron based.

Hmm, wonder if there might be an issue with certain batches of Winbond IC based memory that makes them dislike tRCD of 2 at high speeds. Might explain why TerroH8er and myself have problems with our OCZ EL memory, yet other NF7-S and nForce2 owners don't.
