[Xtrem Insane] 256mo Kingston pc 4200 WR ??

[boblemagnifique]

Hello All

I wanted to buy a ram to test my vmod vddr and I chose a 256mo PC 4200 c4 from Kingston



By chance , it had Chips Micron (D9DCD) which I dont know





Configuration of Test :

C2D 6300 step B2 (Big Typhoon)
Biostar 965 PT (Vmod vddr )
1x256mo Kingston pc 4200 (papst 80mm)
Msi X300SE 128mo
OCZ GameXstream 700w Sli Ready
Hitachi 250go Sata


Max Vddr of benchs = 3.6v (100% because 1.8v origin)




Max vddr Bios = 3.74v , Very Stupid but the mobo still function





Cas 3-3-3-15 at 3.6v



Max screen 461.4mhz 3/3/3/15 at 3.6v

Cas 4-4-4-15 at 3.32v

100% cas 4



Max Cas 4





Cas 5-5-5-15 at 3.28v

Max 592 but no screen (Bug Ram now )




Max Screen 600Mhz (599.99mhs exactly) 5/5/5/12 at 3.32v

Now the RAM boot which 2.6v has minimum, stable Windows has 2.8/2.9v lol, I think of putting it under caskade (- 85&#176 to see the max benchs Cas 3 as well as the max Fréquency Cas 5

ah ah crazy

[metro.cl]

that is a lot from stock my guess is that d9 is similar to others but just needs ton of volts to work at high speeds.

3.6v is just insane

[MusicIsMyLife]

3.6v is just insane

2nd that.

Awesome result. It´s more than my 24/7 on my mushkin lvl2 ddr1.

[MaSell]

I saw same stick yesterday in local shop, 2x256mb set . Mayby I will test them

[Exedy]

crazy results

Hello All

By chance , it had Chips Micron (D9DCD) which I dont know

As ozzimark pointed out D9DCD ICs are indeed CC-37E which are present on my Micron DDR2 IC Info page.
Another version called CC-37E IT is also available.

The only differences between the two:

CC-37E operating temp.: 0°C (32°F) » 85°C (185°C)
CC-37E IT operating temp.: -40°C (-40°F) » 95°C (203°F)

Nice find! They are extremely rare.

You are lucky Intel doesn't have IMC yet

Very nice buddy!

the IT version, the industrially spec'ed chip, is D9GHK

3.6V and RAM is still alive ?

[MaSell]

3.6V and RAM is still alive ?

"Max vddr Bios = 3.74v"



Hmmm, what do you think - will survive 4.xx v ?

[majkel84]

damn nice work boblemagnifique

and thats all what biostar is able to

[oijkue]

awesome
Its the highest ddr2 vdimm that I have seen

[quent]

THIS is an xtreme voltage !

[The Stilt]

I accidentally gave ~3.8V for my Rhino PC2-8000F5M sticks (D9GCT) because my Fluke multimeter had low battery
I noticed this after the SuperPI gave constant errors and the motherboard shut down due OVP.

I ran SuperPI and other benches for over an hour.

Luckily the sticks seem to be completely undamaged.

The modules were cooled with 3mm thick alu spreaders and 80mm fan.

Maybe it is not the voltage alone but the overheating which kills / degrades them.

Hi the stilt

Yes indeed, I think that of fort vddr (+ of 3.3/3.4v) degrades the chips considerably , personally I thus have benchs during 4 a 5 hours between 3.3v and 3.6v not astonishing that my ram doesn't function correctly any more, (it is necessary 2.8/2.9v well for him to go under Windows now )

my biostar 965 Pt has your bios mod (large a thank) it still misses stability in this bios, I have some bugs since the departure (detection of my hdd according to the fsb, fsb max bios of 500, the cuts with my caskade (- 80°) but that remains excellent a mobo for overclocking

I am in the search of vmod Vmch (not yet the vmod vcore ,
I miss 50k ) finally if you have bios or vmod on this biostar, I accept them with great pleasure



Thank all

mine...
KVR also
chip D9 GKW
on DFI NF Ultra II M2

superpi 32M


superpi 1M

need more vdimm here..
btw..how Biostar 965 can have the vdimm such that high?? isn't it max mod @ 2,4v just as the Biostar AM2 boards (TF550&TF6100AM2)?
plz give us pic of vmod up to 3,6v

LOL.... you did the same (not the same, better, you run at 5-5-4, with just 2.44V !!!

[wedfighter]

the chip :


need more voltage here..

[rifcozo]

hynix FC-4 256mb pc4300
maybe its not to bad..
tested at 2.1volt

very good to know OZZi

I think i need to go hunting for some el cheapo Kingston DDR2...& see what i can find
