Semprom 2800 @ 2.7GHz

mofo's · 31 May 2006 at 11:51

Finally got one those DFIs nForce 3 boards and what a board it is!

Currently at 2.7GHz with 340HTT does 2.8GHz with 350HTT but abit unstable, I feel its the memory timings

Any help on these? the board has loads of memory options for tweaks, quite a few I don't really understand!

Did a quick PI test at 1M - 35secs

What ram and what are the current settings?

mofo's · 31 May 2006 at 11:56

Ram is mushkin PC3500 currently with divider (can find out when I get home)

Timings are 3-4-4-11-1T think it may be the 1T need 2T, but can't find adjustment for this!

It'll be named Command Per Clock. Enable is 1T, and Disable is 2T. It'll be in memory configuration.

Beat me to it !

Go to Genie Bios > CPC ( or Command Per Clock ) > Enabled=1T / Disabled=2t

DFI Lanparty UV NF3 250gb

Bows down you are the OC master. Thats very impressive you must be a Jedi.

At 2T you'll lose somewhere around 4 to 6 seconds for SuperPI 1M.

What stepping is your Sempron and at what volts for 2.7Ghz and for 2.8Ghz?

Mikey1280 · 31 May 2006 at 17:54

6 to 8 seconds? It cant be that much can it?

EDIT: nice ninja edit, still dont think it will be that much

str · 31 May 2006 at 17:56

Yeah I hadn't taken into account the ram probably is somewhere around DDR460 which should help a bit at the 3-4-4 timings.

Mikey1280 · 31 May 2006 at 17:58

I mite try this later, to see the speed difference.

str · 31 May 2006 at 18:11

Yeah definately give it a go. I was surprised how much of a difference 1T makes for SuperPI.

rgzcampbell · 31 May 2006 at 18:16

Nice overclock I had a sempron 3100 that did 2.7 with a smidge over stock volts. Changing 2t to 1t will shave 1.5-2 seconds max from your superpi time. Best I got out of it was 33 seconds.

str · 31 May 2006 at 18:25

Hrm, I just did a test and lost 5 seconds SuperPI 1M when switching from 1T to 2T with the ram at DDR400 2.5-3-3-7.

Could it be it's dropping so much because of only running at DDR400 or maybe because I'm clocked at only 2.4Ghz atm due to running at stock volts?

EDIT: Ignore my ramblings.

I see only a ~2 seconds difference on a clean boot with nothing else running.
