Firstly, before I begin, I would like to clarify that I am not bragging or showing off and all the problems I am facing, is real. I hope someone can help me because I am going nuts... rclxub.gif


So anyway, I just got myself a set of OCZ PC4800 Dual Channel Platinum Limited Edition Memory:

So I tot it was cool to have a DDR600 RAM because then I can push my Athon64 to 300Mhz FSB. Problem is, this ram will only boot at 2-2-2-5. Which of course only allows me to do around 210~220Mhz. To get to 300Mhz obviously I have to loosen the timing but the moment I set anything other than 2-2-2-5, I can't boot at all. Anyone knows whats the reason? Or perhaps knows the solution?

My Rig:
AMD Athlon64 3000+ (s939)
ASUS A8N-SLI Motherboard (BIOS modded to A8N-SLI Premium)
Cooler Master eXtreme Power 430W

Please help me... esp those who have used DDR600 RAMs before...

i had a pair of TCCDs, but i have never tried with those kind of timings before.
the tightest ive ever gone is around 2.3-3-4. and even that needed  an increment in voltage.
well, this is scouflys' area, and he should know how to guide u thru this, but in anycase, do u think its the bios of the board? or do u think there is too little vdimm?

I set it to 2.8v which should work for TCCD...

The problem is, I never heard of such thing that if I loosen the ram timing, it refuse to boot sweat.gif

Hopefully soulfly tumbles upon this thread then. I need all the OC sifu's help! notworthy.gif

RP / MAL? some tccd work with 8/5.5. finding the best timing is tricky, but had to go through all the hassle to get the best.

Care to explain more whats RP / MAL?

Read Premable and Max Async Latency as in bios. smile.gif

Currently running RP - 7ns
MAL - 5.5ns

Should be okay right? Sadly my BIOS doesnt have any option to edit those two.

do you mean that your pc cant even boot at 200 @ cl2.5 and 3?

Yes exactly. So is there a way to solve this or is it time to send this ram for RMA?

What has the PSU got to do with booting at CAS 2.5 or 3?

dunno... ahahahah!

maybe the psu supply weak current to the mobo etc etc

Weak current to the mobo shld be giving problem running at tighter timing ma... CAS 2 maybe.

Anyway, I e-mailed OCZ. The staff said that this kinda case happened b4 and can send RMA. But nowadays no more TCCD so he said, he wants me to try to flash the ram SPD. But he has to find the original SPD for this set of rams first. Oh well, wait till he replies me and I will give it a try.
