DDR600 2.5-3-3 1T with Corsair TWINX XL in Lanparty!

Here we go :D

AMD A64 3200+ 1MB L2 CG stepping S754
DFI Lanparty UT nF3 250Gb

Corsair TWINX XL 512MB with Samsung TCCD

31sec with a S754 A64 3200+, my personal new record for now.

The sandra is now 4667MB/s for single channel, wondering will it break 9000MB/s if on dual channel. :banana:

What voltage did you need for 300 @ 2.5,3,3,x ??! Assuming thats 1:1 yes?

2.9V is all it needs. Sure it's 1:1, see the sandra memory mark, 4667MB/s is very high for single channel in S754.

Damn this tccd seems to be flying atm!

is that these guys?

very nice... now go for 9000/9000 DC. ;)

EDIT: didnt realize you had s754, sorry

@ahfung
very nice ...

BIOS settings?

I want bios settings also =)
I must have missed something..

good good 300fsb! How stable is it at that? eshbach said his was good to 285 which is still amazing! mmmm I may need to get a hold of some of that when I go winchester for 300x10 or even 300x11 action ;)

ahfung, what cpu cooling are you using btw?

I've got some Corsair PC3200XL Samsung TCCD, I'll have to try them as well with Oskar_WU's settings :P

What are the Oskar_WU settings like?

Look in his post in the same area as this thread ;)

Thats just sick. You've got yourself a nice bunch of TCCD ahfung. :D

I didn't take reference from Oskar Wu's tips on TCCD's setting. In fact I tweak my TCCD based on the best setting for Hynix D43 which I posted awhile ago.

You shall take a look at Oskar's tip on TCCD first (which is quite similar to my Hynix's tip). But to reach DDR600 2.5-3-3 you need to relax the max async to 8ns in BIOS or A64 Tweaker, this is the only setting Osaka overlooked. Very little performance is lost but you got much more stable at DDR600 while Trcd = 3. If it's still not stable enough you might try adding Vdimm to 3.0V which does help a little.

I don't mind sharing this little secret with you guys, here's internet and we all shall share our wealth of knowledge.

By the way, not all TCCD are equal, nor's the PCB, not all are going to hit DDR600 2.5-3-3 1T easily. In fact of the 2 TWINX XL only one is stable enough for some benchmark. The other one I'd tweak it more or relax some other timings to see if it'd do that too.

For those interested, my 3200+ is watercooled.

I was able to run my tccd chips at 300 with those timings.
But i didnt gain anything in sandra or pi, all i gained was a very unstable computer =)

Tras 3 ? Not 6 or 7 ?

oh sorry that it's a typo, I mean Trcd at 3.

Try 2.5-4-3-7 a run.
Think you get same result but very stable computer.

I get the same results in Sandra with 2.5-4-3-7 and 2.5-3-3-7 on my OCZ PC4400 EL Gold at DDR500.

I'll try an Asynch of 8ns when I get the Corsair to test out my m8's PC.

with my pqi's, i tried 2.5-4-3-7 @ ddr600, it did make it a lot more stable, too bad i can't get it to prime for that long.

anyway, here's a sandra screenshot at those speeds.
10-14-2004, 12:03 PM

I think asynch of 8 or 9 should be prefered at those speed.
Volts over 2.9 should be used when you go 310FSB and beyond, but getting it stable over 310 seems impossible to me.

i just tried async 9 and i couldnt boot into windows, the load up screen would not appear. however async 8 works

nice!

and thanks for the async info.. :)

Here's some OCZ PC3200 Plat. rev2 action on a DFI LP.

Able to loop 3dmark at 305htt but not 310.

Very nice. I will be soon trying to find the peak to my current memory. I'm running HyperX 4000 (2 x 512) and so far w/ 2.8V I've hit 275mhz.

I'm hoping with a good 3.3v or so jammed up it's arse I'll bust 300. Time will tell :)

5GB/s single channel is completely insane!!! :slobber:
10-14-2004, 09:07 PM

I'm now working on the more practical side, 2x512MB with 24x7 stability is my ultimate target.

Now looping prime95 4096K FFT at 290MHz 2.5-3-3 1T, looks like it's gonna pass as well.
