ASUS P5N-E SLI 650i Thread

[dpawl31]

So I have been reading up and apparently the only reason for not running your ram faster than the CPU is that it causes instability because it is not 1:1.

Well, I Orthos'd for over 12 hours with my 5:8 divider, and it is stable as hell.
So I don't see any harm in running it at that, especially since it is running @ stock voltages. (2v) Basically everything gets through my CPU as fast as it can, hits the RAM and gets flown right through there, lol. (250FSB 400RAM)

I was wondering how are you guys runnning 1:1 devider when you unlink it? I can only see 1:1 when you select linked? with my setup I lowered my FSB to 1500 so I can play with the memory speed

Im bought a temp gun to see how hot my Northbrige with the stock heatsink and 53.33C full load so I think that not to bad.

thanks for all the people that had a Positive input on this tread much Love to you guys

1:1 when unlinked is only possible when you match FSB to RAM... intels are quad pumped... so your FSB is 375. Your ram should be 750 (DDR2-750) that will give you 1:1....

Remember our Bios displays actual speeds... The memory is really running @ 400Mhz on my system but in the bios it says 800. My FSB is 250 but in the bios it is 1000.

I can't get a 1:1 with my ram @ full speed because that would require a FSB of 400Mhz, which in turn with my locked 14x multi would make my 2.8 run @ 5.6Ghz... which would last all of 2 seconds and fry it. LoL.

Temp gun idea is pretty cool!

I may try running the ram underclocked to see if I can lower temps a bit... I can get 1:1 if I underclock my ram to DDR2-500... we'll go try that now! Hope I don't have to do a hard cmos clear. . . I have had to in the past when messing with my memory...

[dpawl31]

Oh also keep in mind, when you link it, you manually set FSB and then divider, which finally gives you the memory final which you cant change.

When you unlink, you can't adjust the divider because whatever you set your FSB/RAM ratio to thats what the divider will be. The techage review for the board said they got a 15:16 divider lol... pretty cool.

[dpawl31]

Well how about that, I did it!

First off, whenever I touch the RAM speed (not timings) it stalls before post, I hear the fans spinning full rpm and thats all it does. So I restart, and it fails to post... thanks to the crash free bios deal, it asks me to continue or enter setup. If I continue, its all default bios options... DOH. If I enter setup I can load from my Bios Profile my OC and settings, then reset the ram speed again to the new setting, exit and it doesn't stall? What's up with that!

Anyway... I am now underclocking my ram, and running a 1:1! Sweet. I was ALSO able to lower my timings thanks to CPUZ's timing table. Check the pic!

Anyone think the new 1:1, and the new timings would give me a better 3DMark06 score, or SuperPI?

[dpawl31]

Hmm... I got worse Aquamark and superPI... Could it be true running your memory faster than your CPU is good for your rig?

[trekman]

now it makes alot of sense. thanks for the good advice I will try it when I get home.

[dpawl31]

So I posted about this loss of scores issue in the memory forum to see if those memory guys can figure it out. Here is the link

Glad I could help trekman. I had NO IDEA what I was doing with ANY of this stuff a month ago, and in regard to memory, I have only learned this much in 2 weeks! lol. Good luck! Let us know how it goes.

Did you get the Ninja with the fan? If not I hope you are running 1 of your 120 fans for intake and one exhaust. If you only have exhaust or intake for both, that fanless ninja will constantly raise your ambient temp making it harder for the ninja to remove CPU heat. You just wont have enough airflow around the ninja if you run both your 120s intake or exhaust.

Course you coulda bought the ninja with the fan and me telling you this would be pointless, lol.

I'll look at adding a fan to the NB once I get it build Friday and can see what I have to work with. The Ninja is the massive one with the 120mm fan built in. I also have a 120mm intake and 120mm exhaust fan on a fairly large case. I wanted to put the Ninja in during the initial build so I wouldn't have to remove the MB later on. I think I'll be good to go as far as circulation!

anyone upgrading to vista with this board? I went to Asus site no chipset driver yet.
