check many previous pages b4 when i post i test single sided 512.
even me among the 1st to get those ram from my pc.
if u're planning to oc dun get it.
coz how can u OC if one chip running 64mhz rather than
double sided ram running 32mhz/chip.
looking by those number i can see 32mhz got lotsa room to OC.

loh.... i tot singleside is better than doubleside. for 4 damn years i belive this.

For nForce 2, it's true as double sided are hindered by talkback and stuff like that and the nF2 archtecture isn't that well designed to cope with such matters. Double sided OC'ing demands greater luck in reaching high FSB's and that also with certain sacrifices. Like for my BT-D43 double sided, I had to disable clocks-per-command in order to hit 250 Mhz.

I on epox 8rda+ , and i tested few kind of ram with single sided n double sided. But only when i disable the clocks-per-command , the ram will be oc better.

Yup, because you reduce the cycle time. So the ram isn't stressed out. But, performance will degrade as a result of that. So you have to find the balance where you actually gain back performance with CPC off.

Double sided ram takes up more current too..which is why most mobo limited to ddr333 with 4x512 sticks

since we're talking bout hynix i would say yes to btd43
but half-no to dtd43. coz i test 4stick dtd43 on intel still can run at ddr400
but oc with those 4 stick seem problem coz the memory controller
i guess.

but if on new proc such as venice e3/e6 or intel emt64
the memory controller got even improve for 4x512mb double sided
dual channel mode even for OC.

The mem controller for intel board handles 4stick well. You used 4x512 (dbl sided) at 2T?

My via kt880 have to use slow timing 3-3-3-8 to run 4x512 (dbl sided) at 2T. Any less memtest fail 

lowyat staff told me dfi k8t880 not support hynix chipset last week,sad now.

yohoo my dtd43can run at 265fsb 3-3-3-8 at 2.8v

1T or 2T?

Hmm, if 2T my BTD43 is capable of 2.5-4-3-6 at 2.85v @ DDR550 / 275 HTT @ Dual Channel

hehe .. manage to get my ram running 2.5-4-4-10 1T @ 3V

benchable at 282Mhz
bootable at 284Mhz

the ram prime stable in windows bro?...or inside the memtest?

Hi, my Radeon 9550 is using Hynix DRAMs.
Can use these settings to set the memory timings? or
Can someone show me the correct memory timings for a GC?
