Chasing 29s

[Sup3rman]

I want to run 29s for superpi 1M. I'm really close. Can anyone recommend A64Tweaker setting to improve my time for corsair 4400C25 running at 10x278MHz?

Dropping the TRTW to 1 brings a signifigant performance boost.

just tried TRTW = 1, PC locked-up. I lowered FSB from 277 to 275 and tried TRTW to 1 again, same results.

tried maxmem 104 yet?

Have a look at the tweaks:

Can someone please tell me how the select "CAS Laency (TCL)=1.5" in A64tweaker?

I forgot how do you do the max mem 104 again?

(so the boot.ini maxmem tweak (doesn't always help and slows your system down): look in the advanced options of boot.ini, there is "MAXMEM"

in the boot.ini after /fastdetect add /maxmem=104 (or 105)

for example : multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windo ws Server 2003" /fastdetect /maxmem=104

if the option isn't available through msconfig then the boot.ini will do the trick.

In case you're still chasing 29 seconds, try these settings for TCCD:



Good luck.

Strange... I hit 29 secs at 325*8,5 - using lame divider

you'll get the same preformance if you do 9x307. your mem was still over ddr600.

sup3rman... superpi wont show 29sec untill you hit 29.5sec in the process timer window. your still about 6/10ths of a second slow.

Try lowering the latency and read preamble. That should bring about some performance increase.

I'm still trying... but I doubt I'll get there. I think my CPU is only good for 2800MHz.
I'm not sure if 2.5-3-3 timing will make 29s? I have some BH-5 that will do 270Mhz 2-2-2 but that doesn't seem to be enough either.

check my what does trcp and all that stuff thread in xtreme bandwith. That might help you reach 29's.

async with about 255/260mhz ram 2-2-2-5 and htt 310/315 you shoud get 29s @ 2800mhz obviously with a little tweak

I got a new Booster, my first one would not go over 3.7
I'm hoping to push my ram a little more to 10 x 275 2-2-2 and see what happens.

I'm thinking I need 10 x 278 2-2-2, or 10 x 285 2.5-3-3, 11 x 255 2-2-2 for 29s.
I going to give the memory 4.0v and hope nothing breaks
