hi, can you guys give me ur RAM details (brand, size, single/dual channel, timing and ramchip) and also, how low have u ever clocked the CAS timing?

:) you can cheack this

bh5 and tccd is the best chip so far . and got twinmoss ram also best but i dunno.

bt-d43 hynix ram is the most affordable and good overclocking ram. im using one :P

my current setting 230mhz DDR460 at 2.5.4.4.8 :)

hehe, D-43 chips rock.

FSB269 at 3-4-4-8, 2.7v was the highest i heard anyone ever got them. The highest i got mine was FSB251, DDR502, at 3-4-4-9, 2.7V. Unstable PSU (duh, it's a crappy iCute), stopped me from going any higher. Just got an Enlight 420W, so I'll give it another go when I install it.

Btw, I'm runnign 2 gigs of RAM at the moment, 512 x 4. So my mobo running on a 5:4 divider, FSB254, RAM at 203 Mhz, DDR406 ;) 1 gig of Mushkin, 1 gig of Kingston Hynix D-43.

:) but MD i read at lowyat.net got a bunch of people can 250mhx and abouve with the settingds 2.5.4.4.11 . ur ram can? :)

No, because I have a CrapCute PSU. HOw to OC? Unstable voltages under heavy load. Even now, my OC'ed GT and CPU also hang once in a while, voltage drops below acceptable levels.

ONce i install my Enlight, i'm sure I can go higher. :D

is PSU REALLY that important? and what causes system hang? overheat due to lack of power?

omg. i have nelight . so far so good after using for one year.

borneogeeks, PSU is important for overclocking. with good and reliable PSU the computer get instant stable power so the pc would not hang. if likfe icute than dead :lol:

Hehe, a good PSu will maintain stable voltages even under heavy loads, such as during Overclocking. If your voltages fluctuate alot, you will get system instability. (=

and we lead to PSU EXPLODE which will happen to Maximus deritus if he dont change his psu ASAP> :lol:

Already changed my PSU ;) Enlight now :)

congrates! why dont buy antec 550w?

Cos i dont have money, buddy ;)

weak psu will cost your pc to reboot when overclocking

on a worse case, u'll end up frying the whole system

anyway... back to the topic. so far i've been using three types of DDR ram already:
1. Kingston Value RAM
rated speed : DDR400
rated timing : 3-3-3-8
chips : Hynix BT-D43
max tested : 255mhz, 2.5-4-4-x, 2.8v

2. Hyundai Electronics DDR SDRAM
rated speed : DDR333
rated timing : 2.5-3-3-7
chips : Hynix BT-J
max tested : 262mhz, 2.5-4-3-x, 2.9v

3. Kingston HyperX
rated speed : DDR400
rated timing : 2-3-2-6
chips : Winbond BH-5
max tested : 240mhz, 2-2-2-x, 3.3v

all were tested on the same rig which consist of:
- DFI NF2 Infinity Ultra motherboard with modded BIOS
- AMD AthlonXP Mobile
- running dual channel

basically,
higher speed means more process per clock cycle
lower timing means the length for each cycle

:wub: BH 5 . my long time dream of owning one.

hmm. i changed m FSB to 166. only at 166 my timing can be changed to 2.5-3-3-5 :huh:

JUst rememebr that latency and timings matter less on an INtel chipset than they do with AMD, because with iNtel, youare more concerened withoverall badnwidth and throughput, rather than IPC, (Instructions per clock).

yeah. i remembered tht. u told me b4. why is it that way?

Because Intel run fewer IPC anyway. And thus, the amount of data transmitted per clock cycle, governed by latencies and timings, is less important, than how many cycles you can get through with. (=

There is a serious flaw in that statment...

IPC is always important.. ;) Its just that with increased processing pipelines Intel is less efficient. Not to say that its totally less important in Intel... Well, not really much you can do regarding IPC anyways since its by design... :P But to reiterate, IPC is important to any processor. Its just the different approaches in calculating a performance of a chip. Intel set the standard for their processors as a crank in speed = increase in performance. AMD does the same to a certain extent but puts more emphasis on optimization. Just diff approaches.. :)


Mine is Micron Rev5B "G" chip.

DDR500 @ 2.5-3-3-11 1t

psy is that you? B) cool

The one and only... :P :D

whats IPC? im lost...

IPC = Instruction Per Clock
