If the rest of your ram settings are on auto with the 166 divider and 3 or 4x ldt multi I can only suggest cpu voltage is the issue as with a htt of 246 your ram would still be running at 193.3mhz so can't see a problem with memory.MR.B said:Thanks everyone
Smids, what are your BIOS settings to get that overclock?
I upped the voltage and it was reporting 1.48v but when i run at 11x246 (2.7ghz) it's still not enough, 3Dmark06 always locks up...
And to run stable at 2.6ghz i only need 1.39v so it's quite an increase in voltage and it's still not stable..
I tried setting the RAM to run at 166mhz, tried 3x HT aswell, but no luck. Anything else i can try?

Out of interest does anyone know what happened to Ricco? His work when these boards first appeared was a massive help to me and I am sure many others on here.

you may find that you system will struggle to post if only a single stick of ram is instated in the ddr 4 or ddr 3 slot nearest the cpu socket, if your system gets stuck on the 3rd red led it is having problems recognising your ram. simply switching to outer ddr 1 slot will help your system post with just a single stick. I had the same problem with my old tccd but as soon as you have both sticks in the matching slots it would post. as long as you use the same colour dimm slots your mb will run in dual channel condition.
I've found yellow slots work well with tight timings and orange slots work well for high fsb.
if you still cant run dual channel I suggest flashing to big t's modded 704 bios which has slackened latencies which help your system post with troublesome ram.

Ive got the SLI-DR board, can anyone tell me off hand which sata ports are SATA2 and which are standard SATA?
# Four Serial ATA ports supported by the nForce4 chip - SATA speed up to 3Gb/s - RAID 0, RAID 1 and RAID 0+1 - NVIDIA RAID allows RAID arrays spanning across Serial ATA and Parallel ATA
# Four Serial ATA ports supported by the Silicon Image Sil 3114 chip - SATA speed up to 1.5Gb/s - RAID 0, RAID 1, RAID 0+1 and RAID 5
# Four Serial ATA ports supported by the nForce4 chip - SATA speed up to 3Gb/s - RAID 0, RAID 1 and RAID 0+1 - NVIDIA RAID allows RAID arrays spanning across Serial ATA and Parallel ATA

The chipset ones are just next to the floppy connector and I presume they're the SATA2 ones from the higher speed.

Thanks, that would make sense, 1-4 next to the NF4 chip....rather than the silicon chip

does anyone else have trouble with the 704-2BTA bios?
i cant see my memory speed in CPU-Z in windows and i cant select 150 either on the dividers.

No problems here - maybe it's the opti?helpimcrap said:does anyone else have trouble with the 704-2BTA bios?

why would it be the processor?
I've tried big t's modded 702 and 704 bios on my 146 and use the 704 with my 170 opty and have no problems. great with troublesome ram ive found.
Soldato
Opti's aren't technically 'supported'. It was only a guess because the BIOS is THE most compatible BIOS for RAM. He also mentions the lack of use of one of the dividers. Memory controller = on die so I suggested processor.Hesky82 said:

oscar wu's bios fully support opti's but for him to give you any tech support would be at the discretion of amd, just dont expect any help from dfi tis all.

iwent back to the offical 623 and its fine again now. running at 2.8 on 150 divider with memory at 200mhz.

just out of interest what method do you use to flash your bios
Quick Q guys. i have an ultra-D with 2x512 crucial ballistix in there (not the failtastic 1GB sticks). i am getting another 2x512 in there soon (i hope). any probs running 4 sticks? i have it overclocked at the mo and the RAM is running at 280mhz. am i likely to have to drop the ram on a divider with 4 sticks?
Soldato
Very likely you need to run a divider and 1T isn't possibletomos said:
cheers for the quick reply dutch 
not worried about using a divider that much really since it wont hit the performance that much, i've head running 2t makes a diff but not that much. since this is really my video encoding PC then i would imagine 2gig v 1gig benefit would more than make up for the slight slowdown of 2t v 1t?

Your O/C is likely to drop by about 200mhz or so as the strain put on the memory controller with 4 sticks can really impact on any overclock you have.
