Command rate 2T?

yup, cause the asus board got issue with 1T, if i go 1t it just can reach 230, the board limiting me...

I see. Asus should fix this problem in furture bios update.

Yes, it's in the orange slot. I dunno if my proc doesnt like /11 divider.

Lower the multiplier and see what's the max MHz @ 1:1.

Unlike Venice, Opteron/Venus should work well with most of the dividers.

I've tried, but still cant work. Last time i can run DDR480 nicely with 2.70V 2.5-3-3-11 timing with DFI nF2 Infinity Ultra. Prime for 100 hours also no problem. But with this system, 2.5-3-3-6 DDR480 requires 2.73V and cant really pass 12 hrs prime.

However, 2-3-3-6 can run very very well, up to DDR470. I cant do it with my old AXP system at all.

i think it's RAM limitation

as far as I could recall... Corsair XLPT XMS3200 is using JEDEC spec pcb.... correct me if I'm wrong.

it depend on revision.
revision 1.2 is using the brain power spec pcb.

yea. Mine is using brainpower, rev 1.2

maybe hv to fine tune the alpha timing even more. Almostthere sent me 1 screenshot on this RAM. It is using damn loose alpha timing to reach DDR600 compare to other RAM.

Hi all,
i want to ask about 32-byte Granularity. is it important to disable with tccd?

Thanx.

Forget about Prime95.
Can your ram run other applications (like games, folding) stable at 275MHz or higher?

Can run, but eventually the system will get BSOD even at DDR500. DDR550 is out of reach for sure. Once boot into windows, already feel laggy, and cant do SuperPI 1MB at all.

This is really weird. You must have some really bad batch of TCCD.

I know most companys advertise their TCCD ram modules capable of 275MHz 3-4-4-8.
You can check Corsair website if this ram able to run 275MHz by specification.
May be you should RMA it as these ram modules doesn't work as specification.

Erm... mine is js XMS3200 XLPT, still can RMA even if it doesnt go up to 275MHz?

Updates :

AMAZINGLY, when i set to /10 divider and "AUTO" timing, i m able to pass SuperPI 1M @ DDR533 2.5-4-3-7 @ 2.83V. Now priming in process

Damn... i didnt know AUTO timing works better than my manually set one. Anyway, I hv a fren with the same Opty batch as mine, and running /11 isnt really stable at high speed too.

ALeUNe thanx for all yr help

with the AUTO timing.... try check the value of the timings with A64Tweaker

ah...dun forget to show the screenie here

checked, but the SP2004 eventually failed after 16 minutes too

The screenie

* i've changed Trrd = 3 and Twtr = 2, prolonged the SP2004 near to 1 hour. Before that, it always failed at 896K FFT, and now it always failed at 320K FFT. When i kept resume n try, suddenly BSOD and my printing stops

Now using stable setting first, after printing only play again


Attached thumbnail(s)

Try....

Tcl = 2.5
Trc = 15 (or 16)
Trfc = 17 (or 18)
Trcd = 4
Trrd = 3
Tras = 8
Trp = 4
Twr = 3
Twtr = 2
Trtw = 3

Read Write Queue Bypass = 8x (if possible 16x)
Bypass Max = 4x (if possible 7x)
Max Async Latency = 10ns (if possible 8.0ns)
Read Preamble = 9.0ns (if possible 6.0ns)
Idle Cycle Limit = 256 clks (or lower value if possible)

Alrites, will try it tis weekend, thanx soulfly

wondering if can improve da setting... anyone can help...
settings

my specs in my sig... tis ram wont pass 230... very sad ... if try to push pass 230, will load and run windows but will have immediate error in super PI and SP2004... so i think just stick here for awhile n optimize the settings... 280 is the max for the proc, oledi try wit higher voltage(accidentally psuh until 1.7v) but still cannot...
