I just leave ALL the RAM stuff on Auto, other than setting the 5/6 divider. I'm sure I'll get brave enough to start experimenting, but not just yet. One thing I noticed, with 2x512s of Mushkin BH-5, it used to read my basic timings as 2-3-2-6-1t, and after I played with 1t & 2t a bit, my timings changed to 2-3-2-5-1t. What we really need here, is a BIOS optimization guide, lol. :DQuote:

Just got the comp running!
I hate the bios!
Whatever i change in it, it would not post anything except blinking monitor.
grrr!!
Update your bios to the 9/14 bios and it should fix your problems.Quote:

hmm....maybe we should let the drive-strenght @ auto, like TinTin meantioned already...
w000t!!!
After a final desperate attempt i got it to live!!! :banana:
It wasn't DOA after all it seems.
Once more i tested with one stick in slot 3 and without videocard, like Oskar_Wu recommanded.
A few bios resets later it gave a beep i was unfamiliar with so i plugged the videocard in and...beep!...POST!! :D
I had to re-install windows to get it working properly, the only thing i can't get to work is the onboard LAN.
It seems to me that the onboard firewall is blocking all traffic, i have no clue how to solve this, anyone?
go to configure the lan "card" in network
Good deal. :toast: After all your trouble, I hope your board shows ya some lovin' back. :DQuote:

Yes running Memory 1:1 with the FSB and LDT auto or 3X.
I have found in both socket 754 system I have had that 1:1 on the memory and the LDT multi at default results in the best 3Dmarks,superPI and memory bandwidth.
I have tried the divider but the results where dismal. Am I missing something or is this pretty much true??
What does the LDT exactly do? I have been running it on AUTO for the time being....haven't got a chance to mess with alot of the settings yet.Quote:

The LDT multiplyer determines the Hyper transport bus speed..
The first Nforce3 150 was 600HTT=LDT3X200 VIA K8T800 was 800HTT LDT4X200 the New nforce3 250GB is a full 16Bit up and down and 1000MHz HTT.
Basicly you times the HTT bus to the FSB and you come up with a total HTT bus. The LDT multi determines the value.
I have been wondering if the DFI defaults a Lower value than 5X LDT. If I'm not confused here the Default should Be 5X. and I have yet to find a windows base program showing the total HTT bus speed.
Default is AUTO, I checked it by Sandra, it is running at 4X, matched with S754 CPU, only supports 800MHz Hypertransport, unless you o/c it....Quote:

Yes?? No?? on the 1000HTT 250GB
as far as I know there are only 2 factors that com into play for total HTT bus. that would be FSB speed and LDT Multiplyer.
Sandra HTT
yup my AMD64 3400+ Newcastle AUTO LDT = 4x as sandra says 1600HTQuote:

I have all my settings on Auto, except for Vcore and Vdimm and sandra shows 2X you think as the FSB is raised the board changes the LDT Multiplyer?
or am I looking in the wronge place?
YES, because NF3 250 supports S939 platform too, so it suppports 1000MHz hyperstransport. But S754 A64 officially supports 800MHz only.Quote:

You can just leave it to AUTO, the MB will select the ratio for you automatically, especially, you are going to heavily overclock the HTT.Quote:

but if you set 400HTT, 2X,, can't boot properly, I think there is a bug.... ;)
Ok, I see now.Thanks for the Info.Nvidias site also states 800MHz HTT bus on the 250GB..
I have been reading reviews and they never stated that the 250GB on the 754 socket only ran 800MHz HTT. They always said 'the new 250GB runs 1000MHz and clearly is the fasted chipsetout' Never stating that that only applys to the 939 platform.
and I was wondering why I was getting such good FSB without changing the LDT Multi. on the Gigabyte K8NNXP 754 I had to change the multi manually to run past 230fsb.
Some MBs need to select a proper LDT ratio when you are going to overclock the HTT... but this DFI, full AUTO.... :DQuote:

simple question, when is increasing chipset voltage needed ? at what HTT frequency ? i only used AN50R and always oc'd with chipset voltage set at AUTO so not idea when you need it on DFI
on DFI i have 10x 240mhz 2-2-2-6 1T with vcore 1.5v, vdimm 3.0v, vAGP AUTO vChipset AUTO, LDT AUTO
I got my board running at 291mhz fsb.
But jesus theres so many options in bios about ram i get confused!
