P@N,
try setting the RAM timings manually according to specification and it should boot then.
Okay, I have set my memory to manufactor specs : 4-4-4-12 1t @ 400mhz.
But I don't know the advanced memory timings, like trrd, trc etc, these settings are still set auto
Are you using the black RAM slots? Tried 2T?
This http://rv.page.cegetel.net.perso.ceg...t/MemSet31.zip will give you most of the mem sub timings. These are my bios settings for system in sig:Quote:

I have to put the volts to the NB core for it to boot at 400FSB or above with 4,4,4,12 1t and the tight auto sub timings. Without at least 1.56 to NB it want boot. I took off NB heatsink reapplied artic ceramique and replaced push pins with small screws and nuts with plastic washers on back of board. Now its held down tight with good contact. Added a 60mm fan just by screwing long sheet metal screws between the heastsink fins, or you can hot glue it. This is whats working for me, just thought I would share.
Ok, I have retrieved the advanced memory timings with memset and set them into the bios. I also set all of the cpu functions in cpu configuration to disabled. (black slots are used)
Tried to run 1200 (qdr) 800 (mem) with a multiplier of 9 @ 1,45 vcore and 1,593 vmch it boots and crashes while loading windows. Increasing voltage had no effect, also tried to lower the qdr from 1200 to 1100; this resulted in a no boot ... When rebooted with CPR I couldn't run 1200/800 anymore ...
Turned down the system for a while, and then I could boot with 1200/800 ...
So I can overclock for a little bit now , but it seems my northbridge gets too hot, I can't even touch the heatsink with my fingers.
I already applied artic silver on the northbridge and a zalman nb47j to the southbridge, It seems I still need to add a fan for the northbridge ...
FYI... anyone that wants to know, the 0401bios didn't fixt the 7950GX2 compatibility problem... still doesn't work in this mobo :(
@ P@N Yes a fan on the NB heatsink is a must. The fact that it is heating up means its transferring heat efficiently. Mine without fan gets real hot real fast, but with a good 60mm fan its only warm to the touch.
Okay now I've mounted a 12 cm fan on the heatsink :) And all the heat is gone ... hehehe
Its currently running orthos at 1200 (qdr) /800 (mem) at standard vcore and a vmch of 1,563.
So hopefully it can do much more.
btw. the cpu is watercooled and there was no airflow on the heatsink. so that's why the heatsink even got hotter.
Thanks to Ron61 and Vasko for your help ! :toast: :banana: :banana: :banana:
Official Bios 0307 is out. "Enhance compatibility with certion memory." http://support.asus.com/download/dow...Language=en-us. Too late to try tonight but I'l give it a try tommorow.
what does "certion" mean? Maybe they mean "certain".. well, hope theres no spelling errors in the bios itself, eventhough that would explain alot ;)

Why not trying 0401 if you know it works for others? :D
well, the 0401-bios still doesnt solve the 1T "problem".. Has anyone tried 1T with the 0307 bios?
What's this so called "1T - problem", because I can run 1T on bios 0202 ...
command per clock can't be set to 1T. I have this problem w/ Ballistix PC2-6400 (runs fine at 1T in a P5-B DLX), even at lower than 400mhz mem settings. Randomn BSOD's.
Thanks for pointing out the bios update. Can't wait to get home from work now.
OK, please help me here guys. I'm getting pissed @ my P5B-DLX motherboard and am looking @ getting this board. I have a E6600 and OC it to 3.54GHz on my P5B. Would this board be a good board to have my OC on, and support a 8800GTS? What im saying is, will this board OC as well as my P5B? I would love to have the SLi option for future use, but dont want to spend 250+ dollars for the 680i boards. Thanks
@ sbinh I was just getting the word out that there is a newer bios posted at asus site. There is already a post in the asus forum that 0307 is bad. The post says he can't get into the bios set up screen, but it will boot into windows, which is totally useless. So its probably better to hold off on this 0307 til more people try it, unless you have nothing to loose. Im stable with 0202 but I was hoping that the new bios would relax the memory auto sub timings. Memset shows most but not all of them. The 1T problem that some people have is most likely caused buy the tight memory sub timings.
@newls This board with e6600/xeon 3060 and g skill HZ seems to be a good combination. I had no problem getting to 3.67ghz 408 FSB 4,4,4,12 1T. I stopped at 3.67 because the sub timings are so tight that it requires 2.5 volts to mem to be stable at 423 FSB 4,4,4,12 1t. I haven't took the time to try to figure out the timings. The board works well with sli. I score well over 11,000 3DMark06 with 2 7900GT's @ 691/801. I have had no stability problems.
OMG, this board seems like it is unbelievable....Quote:

Ran SPi 1m, 4m, 32m and the times are the same. If there were any changes to any hidden memory sub timings it would show up in SPi times so 401 is just 202 with the sli-ready memory option. Anybody else try the 307?
Added waterblock to NB, additional cooling seems to have helped things a fair bit. Can't say 100% as the crucial wasn't 1T tested under stock NB cooling, but seems to be higher FSB than others can make using stock sinks and 6600/crucial anni combo :)
Can anyone else confirm the same?
http://drunken-student.co.uk/pics/pc...T_test_449.JPG
I don't know about Crucial (and other brands), but with OCZ (gold XTC) I was able to run at 1T with stock cooling on NB (up to 425-FSB).
IMO, I like P5B-Dlx than this board .. except for the SLI option. With P5B-Dlx (same CPU, RAM, cooling, PSU ...) FSB can go up to 475 (tested).
Coming a little late to the party but I have a P5N-E board and e4300 sitting at home in the box. Awaiting RAM which won't come till next week. I am matching the board and CPU with 2x1024MB of Corsair XMS DDR2 800 4/4/4/12 RAM. I will be running a watercooling setup with a 1/2" loop on the CPU and the NB and Swiftech 159 on SB.. A single 8800GTS which arrives next week tops it off. All going into a Lian Li 7077A with a PC P&C Silencer 750 PSU. The beauty of this is that except for the CPU and mobo everything is used or traded and my old gear should cover the bulk of the cost of the rest.
My plan was to set it up on the bench, flash to 0302 and then load XP on a RAID 0 array with latest Nvidia drivers. If it all looks stable I'll install it in the case on water. After reading thorughthis thread I am a little lost. So, my questions are:
1. Should I leave the BIOS at 0202 or go 0307? How about 0401?
2. I'm an AMD guy so what is an acceptable Vcore on th e4300? Is 1.6v safe.
3. The reason i am concerned with #2 above is the Vcore droop reported on this board. Is it as bad as reported (BTW I don't use Probe, I use Everest Ultimate)
I know on my A8N32 you must have CPU Overvolt enabled to get a stable Vcore. With water there shouldn't be any problem overvolting the NB which seems to be necessary for this board. Any other things I should do to get a good OS load and avoid any issues such as driver problems etc.?
TIA for any info.
Asus took down the 0307 bios and now has 0401 posted. Totally useless because its basically 0202 with a different number. Here is the description:
P5N-E SLI BIOS Release Version 0401.
1.Reduce S3 resuming time.
2.Change CopyRight year from 2006 to 2007.
As you can see Asus addressed the most pressing issues. I think I'l sleep better knowing the copyright year has been updated.
I finally got over 500 FSB with this board. Changed the CPU to a x68 and there it was. I think my old E66 was reached a FSBwall there around 487. MaxFSB now seems to be around 510

Thanks Ron, I'll redo my floppyQuote:
