Winbond DH-6 ??

I was astonished by this 200 go seagate IDE :

Your Mission:
buy 7 more harddrives, then desolder the chips and place them on a TwinMOS Speed Premium 256mb PCB

ETA: 1 week from now.

The fate of overclocking rests with you misteroadster!

[misteroadster]

Héhé , what a job !!! :D

[Dissolved]

even if thats 8mb which i dont think it is.. 8x8=64mb

Dont 256mb sticks use 16mb chips? 16chipsx16mb=256mb

[misteroadster]

i ve ever seen BH5 chips on hard drive.
Probably not stacked :confused:

ive seen bh-6, but 2mb chips...


Also, even if you did do a resolder job, the SPD timmings on the hdd ram is probly horrible..

So you'd need a SPD programmer/reader

[Rabbi_NZ]

lol

please dont take me too literally or seriously... i rarely do.
besides all the problems you guys have pointed out can anyone see themselves sacrificing multiple harddrives for 1x256 of DH6 RAM?!

[justwOo]

OPP will do it! :D

Very easily resolved. Just buy a ram chip programmer, figure out how to use it and just reprogram your 64 MB stick and OC Like Hell!

interesing.... Winbond needs to intro BH-4

[TekXoID]

Probably a very fast but very low density chip you've got there. I hope my TWINX1024-4400C25 TCCD does the trick when it gets here. :D

SPD is not contained on the chip itself.

By the number of leads that look attached to something I would say its more likely only ~2mb of the chip is being utilized.

[Foxie3a]

My Maxtor 250gb uses a Winbond *H-* chip, can't remember what it is, but it is 8mb. I'll look sometime.

Is the SPD on the chip itself? I always thought that it was one of the really small chips on the stick of RAM.

[saaya]

those are 2mb or 8mb chips, memory sticks usually use 16mb 32mb or even 64mb chips :/

cant wait to see 32mb versions of that stuff though :D

[LorD_Kvadd]

My old Maxtor Diamondmax has a DH-6 chip also. 8mb cache :)

[STEvil]

saaya - I doubt its a 2mb or 8mb chip as I have seen BH-6 (using BH-6 for example since DH-6 has not been seen on ram sticks) on other drives and producing the same size chip with two different densities and the same "name" would only serve to confuse manufacturers (as well as buyers of the chips to put on ram/hdd/etc) and make for a horribly inefficient manufacturing process due to size as well as the need for different machines for the same chip..

I think only part of the chip is being used.

I cant read the full last line, can you tell us what it says misteroadster?

"SPD" is located on a small chip that will be on one end of the ram stick, there may be one on the underside of the HDD or it could be contained within the HDD's own SPD.

I also found such a DH-6 chip as hdd cache. It may be very fast, but it's not worth it to be unsoldered, but you may put a 32MB bh-5/6 there... it could possibly speed up your hdd :lol:

[Xassius]

SPD is an EEPROM on the module, not the chip.

A HDD wouldn't need a SPD EEPROM chip anyway - it doesn't need DEFAULT timings - since it is not designed as a "plug + play" thing like RAM is.

[STEvil]

it does however need an place to store the instructions for all the chips you find on the PCB of the drive.

32MB Cache for HDD

is a killer :hehe:

Yep, but the firmware may need adjustment. :D

I've seen a Maxtor 40gb 2mb cache hdd with Winbnod Bh-5 :stick:

May also be a "retail" 32mb IC ;)

I assume, manufacturers could be buying those mem chips from winbond that did not get through the test, maybe dayum cheap! :D

The amount of memory they use may be defined by firmware -> hack it to 16 or 32MB and be a happy camper ;)

Put 32M BH-5 there instead ;D

DH6 has been out ages boys, its nothing new. Its primariliy used in HDD's etc

Hehe. Let the boys dream their dreams, mate ;)

i think dh-6 is an old sd-ram chip from winbond
