but AM2 IMC runs at the same speed as cpu core

1:1 means the RAM would run synchronously with the FSB. There must be some settings in the BIOS? I'm not sure what name they give to it tho'.

1:1 only applies to DDR.

When AMD move to socket-AM2, there's no such thing anymore. DDR2 speed is derrived from cpu clockspeed, and it depends on the cpu multiplier.

Look how complicated it is...

i wonder where bro soulfly got the table at the first place..
it's help me alot on AM2 ocking.. many˛ days back..

AMD - Unfortunately, the CPU we are using for testing is a 3400+ with a rather low CPU multiplier, at 9x. This limits flexibility a bit, but it was decided that keeping the CPU clock speed at 2.8GHz by raising the HTT up to 311mhz and leaving the multiplier at 9x. On the AM2 platform, there are 4 different memory ratios:
DDR2-400 (1:1) - Gives CPU/9 memory divider, which sets the memory to 311MHz
DDR2-533 (4:3) - CPU/7, sets the memory to 400MHz
DDR2-667 (5:3) - CPU/6, memory to 466MHz
DDR2-800 (2:1) - CPU/5, memory runs at 560MHz
(Note: memory ratios are still calcuated the same way as DDR1 based K8s. See A64 OC'ing Guide for further details on this)

Another one of how it can be set:

The BIOS would somehow have to tell what frequency would the FSB, DRAM, etc runs. The settings and options might be different but ultimately, there must be somewhere to set a synchronous FSB:DRAM?

hi guys,where can i get active ram coolers.try to find in bulk section,tak jumpa lah...and guys should i change my ram.now im using normal ram kingston pc6400..is this ram good for OCing??...i think wanna upgrade my ram to high performance one..any recommendation??..how much crucial ballistik now??

There are some by allngap or you can get those Corsair, etc.

allngap??is the active ram cooler rite..??..if corsair high performance rams,how much haa now??

allngap one is very good ady~

yaa where to get those,at lowyat shop??which lowyat shop..if someone of you selling it..please do PM me kay..

Search for this forumer. AllnGap.
And find his topic.

-pWs-

thanks dude

The great table provided by soulfly and also in am2 thread gives people a hint and clue b4 start buying hardwares. Well, it helped me a lot back then.

Just curious how low can vdimm go for crucial ballistix tracer? One stick of mine could pass orthos/memtest stable at 1.8v while the other at 2.1v. So had to run 2.1V.

What platform you are in? Is it the same slot you tested both of your rams??

-pWs-

noob which was conned by advertisements detected.


for which is the "corsair high performance rams" that you might be referring to?

lol lol.

The current best overclocker would be the Corsair Dominator. But do remember as well, anything else by crucial beside the dominator are nothing. The last time i saw it was RM2900 retailing at lowyat. Go figure.

As for ram cooler, those branded ones are crap compared to AllnGap ram cooler, he picked some very very nice fan to go along with it providing very good air flow at an extremely low noise =)

their high end is very good,but the corsair xms2 is the worst..never try tht dhx(the latest one) yet..the dominator u said is the ddr3 or ddr2?

both DDR2 and DDR3 version of dominators indeed does dominate its market... just that the price is a huge letdown...

I normally frequent quite a number of other forums and most people are on Ballistix (that's for sure). Of course, there are also people with other types of RAM
