1. yea both sticks boot individually. both sticks work fine, no issues there.Quote:

sent asus tech support and email, a guy on the asus forums had the exact same issue. so i'm guessing its a bios problem.
is there any beta bios's floating around newer than the latest 0704.
Which BIOS is better, 0702 or official 0704?
Can you help me reach 500FSB for 24/7 stability?
So far I got 3 hours of Orthos Blend using these settings:
CPU Ratio Setting: 6.0

NB Clock Skew : 200ps
EDIT: CPU and RAM ruled out, CPU works even 3.6GHz with 1.225V, RAM 533MHz with 1.8V.
1.30V NB seems to be most stable, 1.28V and 1.32V was max 40min stable.
Now testing 8x500, same settings, which are the most stable for now.

@aiya , have you set your ram voltage manually ? I would still try all slots just to make sure they work .
@ Grimreaper , if you can get 3 hours blend you are pretty close to being stable . Have you run memtest to rule out ram or small fft to rule out cpu ? I am still on the 0704 alpha bios here and it's better than 0702 IMO .
looks like a nice mobo..any major issues with it? as solid as p35 deluxe boards?
thanks for the advice, i'll play around with it more later and report back. everythings set to auto in the bios. except the ram frequency is set to 1066mhz. because leaving it default set it to 800mhz.Quote:

These are my settings for 4ghz with 8 x 500, I don't use LLC as the rigs are always under load ( 75% Folding at home ), I need 1.28Vcore for my E8500 under load so I need to set 1.325 in bios to get there... I estimate 1.375-1.4 for 1.33 4ghz operations...if ya like LLC enable it...Quote:

What's the story of memtest being buggy with 2GB sticks ? Memtest for windows ?
In fact , my mem @ 1128MHz with 5-5-5-15 and trfc=55 I get no errors with memtest86+, but in windows with memtest (from hcidesign) I get some errors !!! few but some ...
Any idea what's going on ?
@Cob: Awesome Job! What kind of volts are you giving in BIOS? I'm having stability issues past 3.7Ghz (462x8)
@Lee: I'm Prime95 Stable @ 3.6GHz (450x8) with the following settings - but I'm getting instability @ 3.7Ghz (462X8) ... can you recommend what should I start upping or changing in BIOS to get stability?

Also ... I'm hovering around 66 - 70 degress on 100% load during Prime95 or OCCT ... anyway to lower the temperatures adjusting anything in BIOS?
Try upping the PLL. Might need some more vcore too.
What's safe (or max) values to stay 'under' for vCore, PLL, FSB & NB voltages?Quote:

NB - Doesn't really matter tbh. Might get too warm at high voltage tho.
You also have to remember that the board probably overvolts, so what you set in BIOS is probably actually more in Windows (apart from vCore ofcourse).
Are these three the primary volts that affect stability? I guess the reason I'm asking is - I want to determine in what 'sequence' I should start upping volts in order to achieve stability at a higher overclock.Quote:

I found that PLL made the difference between 450mhz and 470mhz. After that I had to start fiddling with FSB Term and NB.
But every chip and every board is different, and what is good for one persons set-up may be useless for another persons set-up.
Agreed.Quote:

hi guys,
I'm considering getting this board, but i'll also be looking for a 4GB kit. Choice in the UK is a little limited compared to the USA, will this one be ok?
If not, on the same site, can anyone recommend which set would be best for this board?
This kit is much loved.
Tho, as with most things, it can be found much cheaper elsewhere.
Which CPU will you be using?
thanks cob. Where should i be looking for the good price? :up:
EDIT - memoryc.com has a good price, was that who you meant?
I'm looking at the Q9450, but i'm open to suggestions.
Yip Memoryc.com, tho that offer's only on til today.
Personally I use this with my Q9450.
wow that's cheap! No issues with the P5Q-D at all?
Nope. The P5Q-D runs 8gb of it fine.
Then by what I'm understanding, in this motherboard, when i set an x value in bios, in the windows that value will be greater than x?
Example...if i set 2.10v to memorys, in the windows this value will rise to 2.18??? apart from vCore, because in the windows the voltage it's lower??
thanks guys
Ok so I've got some more weirdness. The thing is 2 hour OCCT ram test stable @ 400FSB with a 6 multi. (for 2.4GHz) at 4-4-4-12-2T timings. It is not stable at 5-5-5-18, 5-5-5-15, or 4-4-4-12 @ 400MHz 1:1 @ 8 multi. It will run 800MHz fine with a 5:6 ratio @ 2.66GHz. I'm really not liking how picky these corsair sticks are. Considering there are 2 bad sticks and I ordered 2 sets and they are both from the same lot I may just return both of them and then get something else from newegg. One more note before I do some more reading. Before I left for work this morning, I set everything to auto, (timings, voltages, etc)> and set the FSB at 400MHz and the ram at 800 MHz, and it appeared to be stable (OCCT had run for more than 30 mins), ususally it would crash before that if it were not stable. I will have to make sure when I get home, but it just seems like these sticks of ram are going to require EXACTLY the right settings, and this is only for a small OC. Going to talk to a newegg customer care rep now....Lee I will also try your recommended settings when I get home tonight too.
