Bro, are you using the mainstream Twin2X with the black heat spreader? I believe can run 4-4-4-12 at 2.1V and slightly lower at 400mhz. I run fine at 412mhz at CL4 on 2.1V but I think mine is rev 5.1, promos chip.

Kindly advise the maximum speed I can go. Currently running 470mhz at CL5 on 1.95V.

I did try 1000Mhz w CAS5. Higher than that, never try.
My Vdimm high maybe because of i running 4 sticks of TwinX that time.

Your hardware details??
I heard that Intel platform uses less Vdimm [same frequency same timing] if compared to AMD platform.

tahts because intel chipsets use 2T timings instead of 1T, but for intel, it makes little difference

this is so true in my case atleast. DDR2 1000 @ 5-4-4-12 on intel platform need 2.2v, on amd w same settin, 2.4v...

wahh!!!
nice overclocking... 1035MHz...
so means my XMS2 Twin 2x 2048-6400C5 DHX can go up to 1024MHz too....
wa nice results there

Feb 4 2008, 11:35 PM

why not? max you may go is 1200MHz, need to increase voltage la....
and your motherboard must also be able to support it...

anyone done that B4 ?

I think it is hard to achieve 1200MHz unless ram w D9 chipset [D9GMH only available in version 1.x]
Not sure about DHX using what chipset.

i tried to change the timing to 4-4-4-15 wit voltage 1.95v..but cannot..dunno why..1.95v is teh max voltage for vdimm in d bios..

as for the chipset, mine's hynix..

Not bad laa

Feb 5 2008, 07:45 PM

What platform you use?
You will probably need more Vdimm to achieve that speed and timing if using AMD platform due to the memory controller.

Revision of ram is stated on the ram heatsink, n it call version or in short ver.

After adding another 2GB kit of XMS2DHXC4, I have got errors running memtest86 on test#3. I can't set the timing to 4-4-4-12 like I used to when I am running on 2 modules only. With 4 modules, I'll have errors on test#3. Need to loosen the RAM timing back to C5 in order to solves the problem. RAM voltage set @ 2.00V

It seems that running 4 RAM modules is not really recommended. It will reduce OC rate and increases memory errors.

for amd, i think you would be referring to am2 setups right?

1T is better then 2T in amd platforms, but, i think stability is an issue with 1T beyond 900~1000mhz regardless of timings

increase your tRFC.. to 52..
or more.. on 4 sticks.. try it..

so far i go 1024Mhz 55512 2.1v.....sadly this ram just cannot reach 1066Mhz nomatter how much vdimm i pump nor losse the timing...

if i low abit the clock to 950Mhz i can do 5558 with 2.1v 5548 with 2.2v
