some notes from last night's testing at high FSB for 3D stability



first of all............if i get a 32M SuperPi run i should be 3D stable as well ...very good indication

actually using AM3 is probably quickest way to find out

now the settings....didn't take me long to get to this but there is a fair bit of trial and error and with subsequent testing i realised these settings are sweet spots atm

here are the volts set in bios which gave me the highest stable FSB i could benchmark with (595MHz)

Under System Voltages Section:

CPU Core >> set value required for MHz OC
CPU FSB >> 1.45v
Memory >> set to value required for MHz OC (1.9-2v is plenty for 2GHz speeds and decent timings)
Nforce SPP (NB) >> 1.45v (VERY important) going lower or higher reduced stability > higher probably due to possible better cooling required (will have to test that but NB is generally pretty cool
Nforce MCP (SB) >> 1.75v (PUT A FAN ON SB)

LEAVE GTL REF at AUTO >> system will determine the best settings (-80 for me at high FSB) >> for stability at ultra high FSB you can also try dropping it to -90 to -110 otherwise leave it at auto


Note in RAM settings there are two settings called P1 and P2 which require you to increase volts manually or you will corrupt your windows as the chipset latencies are set very tight particularly when both P1 & P2 are enabled. For high FSB testing i could not boot even at 575MHz FSB with both P1 and P2 enabled (probably would work with better cooling on NB and possibly some more volts). I had P2 enabled for my 3DMARK runs which i was very happy with

RAM Settings >> i normally set main timings 8-7-6-20 1T and rest are left at auto which i tune through memset

Lot of testing there Dinos, really good stuff. Nice set up

Awesome stuff Dinos... seems everything for default is loose until you tighten it up. What's the difference in FSB between default loose settings and tightest for 32M best times ?

dinos22

loosest to tightest from bios you can gain a minute in 32M

eva2000

I mean in terms of max FSB that is 32M stable

sounds like good old 680i. seriously good work here dinos on this board. you have all but single handidly sold me a reference board but i am just having trouble justifying buying another $300+ board this year already. and this one comes close to $400 after taxes and stuff

i just want to play with the new stuff like you guys though...looks like so much fun

Hey dinos how's the board perform with Vista/Win2008 ?

dinos22

done some more testing on my single stage last night

my first ever voltmod as well
did vcore mod on 8800GT card i was benching on and went from 700MHz core to 800MHz core :up:




Got some decent scores

299K Aquamark3 (4th fastest run on HWBOT)



3DMARK05 28337
seems poor >> need some help with this bench i think heheh




3DMARK03 48744
seems poor >> need some help with this bench i think too heheh



3DMARK01 92012 (2nd fastest on HWBOT)
didn't do any extra CL runs ... was in a rush
