Anyone played around with the SLI memory option in the bios and found it useful??
Actually I was being sarcastic about the 401 because the only real difference I can see is that it has the sli-ready memory option. Im using the 401 beta thats been floating around a few days. Maybe I should flash to the official 401 just to make sure they are the same. 419 FSB 1:1 4,4,4,12 1T 3769Mhz is the best stable overclock I can do so far. At 423FSB I get errors in memtest no matter what the voltage. I get better performance at 3.67Ghz 408 FSB mem 408 4,4,4,12 1T than I do at 3.8Ghz 475FSB mem 475 4,4,4,12 2T. I just wish I could see all of the memory sub timings the bios auto assigns. This is still a very good board for the money. @ John44 I don't have sli memory so I can't say.Quote:

I have a steep learning curve ahead coming from a strictly AMD background. I can overclock them in my sleep but Intel is a whole different animal. The last Intel I O/Ced was a P4 Northwood on air. Very nice chip BTW.

Pretty sure it's not maxed there too :)Quote:

Have you tried MemSet 3.1 It will show all the sub timings in Windowshttp://rv.page.cegetel.net.perso.cegetel.net/MemSet.zipQuote:

Guys, we all know this board has a big vDroop problem, and some members are working on a cure. But right now we need some help. We need someone with a multimeter to take a couple of measurements to backup someone else's findings. I left my multimeter in 'merica, so I can't help. But can you?

Oh, and zeeke, I've read on another thread (at AnandTech) that people have acheived greater memory speeds with increased NB voltage; bump it up to 1.39v. Also try lower/raising your mem voltage. Yes, lowering sometimes works better. I've had my mem up to 1050 and it's just some non-Micron SuperTalent PC6400 memory.
Try and set memory and FSB speeds (when running unlinked) to end in 2,4,6 or 8. These seem to help on the stability front. Also double check your memory speeds. You may find setting 366 unlinked doesn't give you 366 "real", 367 then moves you up to the next divider.Quote:

<edit> Guessing from sig its the Team stuff? shouldnt have a problem at that speed, where's your CPU running? Assume your using 2T timings and 2+v on vDimm? </edit>
dlxmax: its not the memoryspeed im trying to increase per se, these puppies do well over 500 with 4-4-4-10-2T on this board, I want to increase the 1T max.
I'll have a look at those measuements when i get home from work, personally I haven't experienced the droop as bad as coupli. Last night I measures vdrop during 2x32mb Spi and with 1.57V idle it drops to 1.53V-1.54V during full load. That is real though, the probe is showing ~1.3-something.
Yeah its the team mem, but its the 1T i want to increase as staded before. @2T these mem do over 500 easy @ 2.4V (real), 2.3 chosen from bios, but the board seems to overvolt the mems a bit.Quote:

Chipset voltage and cooling may help you out there then. Stick it up to 1.75v option and see if you can push any further.Quote:

You have to up the volts to northbridge if you want higher fsb 1T. Anything above 400 fsb 4,4,4,12 1T on my board requires 1.74v. Ive ran 1.74v on mine for a month. Currently benching at 423fsb.
I am running NB @ 1.74V still doesnt matter,
Highland3er-
Are you using the CPU overvolt option or do you have it disabled? On the A8N32 SLI, CPU Overvolt stabilizes the voltage and I was assuming it was the same on this board.
zeeke try different fsb, mine will not boot at 412, but will run prime at 413. You may be trying to boot in a dead area of fsb.
Didnt seem to make much difference either way. Usually run it to try and compensate for the vdroop.Quote:

You might want to change TRc .. it might help to run at 1T ... :D
Yup. I've not found any setting that worked at 1T with my mem either. Some say the bios settings are too aggressive to allow a lot of mem that would run at 1T on other boards to run at 1T on this board. Perhaps a future bios will fix this. Until then, be with me at 2T ;)Quote:

EDIT: I think cooling is the biggest issue with this board especially the NB. Last night I opened my window and let the cold air drift into the box and was able to reach my best OC with .05 less vcore set at 1.475 (usally 1.52) and the NB at 1.56 (usally 156 - Max) and I seemed a hell of lot more stable.

This is a compare between different memspeeds, all other settings kept the same. It doesn't really make a difference, atleast not in 3dmark06, Superpi is a whole other beast though..

Any new beta's out??? I need my 7950 working :P
