You've to replace a RAM chip and then ask me for the right sdram_init value.
Have anyone modified their WL-HDD and added more RAM?
I have not found anything on this, but since the price for the WL-HDD is so low, I'm willing to attack mine with a soldering iron I'm just curious if anyone has tried this already, or whether it is at all possible.

Ofcourse Just need to find the RAM chip and an equivalent bigger chip. 64MB would be just superb, allthough 32MB quite OK It's been a while since I opened mine, but looking at the picture http://files.wl500g.info/asus/wlhdd/img/wl-hdd1.JPG what would be the RAM chip? The upper right "hynix" perhaps? And the flash being the MX chip?
Good guess :P

Do you have a problem with your Asus? -> UTFS
Newisys NA-1400 NAS info (4x hotswap SATA, 2x gigabit ethernet, 2x USB 2.0)
any update about this toppic ?
thanks
Does anybody already tryed to change de RAM chip ?
What chip to use in replacement ? Hynix seems not to have a 256MB or 512 MB chip in 32 bits (the 128 MB installed in the ASUS seems to be EOL)
Are the extra address pins (A12 / A13 I guess) connected to the address decoder/Broadcom chip ?

A french newbie
ASUS WL-HDD + Hitachi 40 GB 4200 rpm
Dell Inspiron 8200 - Pentium 4 M 1.7GHz - 1GB RAM - GeForce 4Go 64GB - Hitachi 80 GB 7200 rpm
If I was to add upgrade something in the WL-HDD, it would be the CPU. The damn thing slows the WL-HDD so much :-(
Did anybody out there once a time resolder a bigger RAM chip into the WL-HDD.
I want wo do that becouse I am runing out of memory. Now the WL-HDD swapped 26MB on the harddisk and with the streaming client software its become not even less
So I will be glad about every hint of modding my WL-HDD.

Hi there,
just to bring this up again:
We have a HY57V283220T-7 on board.
Regarding to http://www.hynix.com/eng/02_products...RAM%20FBGA.pdf
HY : HYNIX MEMORY
57 : SDRAM
V : CMOS 3.3V
28 : 128M (Bit!)
32 : x32
20 : 4Banks / LVTTL (not important)
t : TSOP
7 : 143MHz
Have a look at EOL Products.
Here is our chip: http://www.hynix.com/datasheet/eng/d...283220T(P).jsp
So we have 128 MBit / 8 = 16MByte.
From http://www.hynix.com/datasheet/pdf/d...)T(P)(0.9).pdf :
86 pin TSOPII
400mil x 875mil
0.5mm pin pitch
So now we will search for a bigger one with same technical data.
Bad news: Looking for the biggest SDRAM we only have 256Mbit (32MByte).
Next bad news: Have a look at the 256Mbit chips here:
http://www.hynix.com/datasheet/eng/d...&SUB_RAM=256Mb
The x32 organised chips are FPGA. [HY5V52EM(P) and HY5V52AF(P)]
All TSOP Chips are x16 organised. [HY57V561620FT(P) and HY57V561620CT]
So what? We will not be able to find a bigger chip from the same manufacturer
The golden question is: Do we find a pin compatible, x32 organised chip from an other manufacturer?
I am not an expert. Maybe someone of you has an idea?

I have search around in forum ... there is one thread in wl500g section ...
RAM upgrade WL500g Thread
Yes I know we need some other sort of RAMs but it is a nice tip ... to think about ... modify it a bit for wlhdd ...
I will thinks and report maybe at the next week end
Martin
they use x16 organised RAM.
We need x32.
But i am not an expert...
Hi
yes I know ... problems is that we have not much space inside ...
we can switch 2x 256 mbit (16bit org) together on a small board, but it not very easy because all is very small 0.5 mm pins distance :-( ...
fpga ... maybe there will bve a socket for that 512 Mbit chip, but there's problem to connect to the pins from old ram ...
I'll have a small iron from my smd times, but ...
other side ... all data is eol ... I think it means "end of life cycle" ...
all old sdram have only 16 bit sdram ... or am I wrong ... maybe newer ones ... I will seach about some informations ...
Martin
512MBit... 64 MByte....
That would be cooooolllll. Gimme a chip and a layout.
I will burn it down
Did some smd soldering 15 years ago. But its like cycling... you will never forget how it works.

Hi there,
i have an other idea, half offtopic:
what about using an USB Stick for the swap partition?
pro: The stick is faster in access to small "files".
con: only USB 1.1 -> Low bandwith
con: lifetime of USB Stick when used as RAM (many read/write)
What do you think?
Would swap on Stick increase the system performance in comparison to swap on HDD?
wengi
Ok. Did some search. The result 64MB could be possible !!!
What about Samsung?
See here for overview.
Here for more precise overview:
We need the K4S643232H-TC70:
This one is still produced and pin compatible.64Mb (512K x 32bit x 4 banks) SDRAM, LVTTL, 143MHz in 86-pin TSOP II package. Operational temperature range from 0°C to 70°C.
My problem is: I have no idea where to buy it. I am in germany and did not find any reseller
The big ones have it on stock but i only need one and not 1000.
