ASUS P5N-E SLI 650i Thread

[Mr Pink57]

Just curious what ram slots you guys recommend as the manual tells me nothing about what style of dimms to use in what slots. I thought the black ones where the ones to use but now I am unsure.

Doesn't seem to matter, I get the same OCs and such no matter what you use. I use the yellow slots, but there shouldn't be a problem using either.

And yeah, even with 1.748v, no go past 477FSB.

I love that board. It takes my mem and runs thouse 3-3-3-4-1T @ 740 mhz Ofcorse, 2,4 volts but who cares. Burn baby, burn.

1050 Mhz 5-4-4-8-2T didn't give me any perf boost, so trying to have as low latency as possible.

I use slots 1/3...it just seems right lol.

Really? I get a TON of smileys under the more link

and that's only about 1/6 of them!

I should be getting this board Thursday from Newegg. I am going to use the e4300-CPU and will be trying for just a 3000MHz overclock which should be attainable I hope. My ram (2 gigs) DDR2-800 will be very good quality.

What I have been reading so far is that I should use a 1:1 divider to have the best stability. The e4300 multiplier is #9 so… 9 x 333FSB = 2997 which would also run my ram at only 666 MHz (yiks the devil)….. I know nothing about overclocking….I would like to have my CPU running at 3000 MHz and my Ram running at 800 MHz at least, I think I would be upset at running my ram lower than what it is capable of doing… Is there a way to do this while retaining the same stability as the 1:1 divider provides?
Can anybody give me settings below on what they would start to use?
Does anybody know what “Sync mode” is compared to 1:1

FSB memory clock mode- (auto) (linked) (unlinked)

FSB memory ratio- (auto) (1:1) (5:4) (3:2) (Sync mode)

FSB (QDR) MHz (800) - (533 to 3000)

MEM (DDR), MHz (Unlinked) (Linked)

To get ram at 800mhz you'll need 400mhz fsb, if you want to run 1:1 that is. Thats 3600mhz, a large OC. You could run 800mhz and 333fsb if you wish, but its going to be a weird devider.

Sync mode is the same thing as 1:1 i believe, puts ram "in sync" with the FSB. Correct me if im wrong

why not drop your multiplier to x8 and run the e4300 at 400 FSB (if it's capable of it, I have no idea really--your c2d e6400 certainly is, since that's exactly the OC I'm running)? that would give you 3.2 GHz and 1:1 ratio.

whatever you do, what I'd do to start (after you get windows and drivers installed, blah blah) is:

1. manually set RAM timings to stock (and set to 2T)
2. set to unlinked, and ratio to auto, vcore to 1.25, vdimm to stock (or auto), NB to 1.3x (can't remember what it is)
3. set CPU FSB to 1200 (this is a 300 clock speed, remember recent intel chips are rated at x4 the clock speed)
4. boot to windows and check orthos stability for 1 minute
5. save your OC profile to one of the slots (so you can load it back if you become unstable), and increase CPU FSB by 50
6. repeat 4 and 5 over and over again until you run into trouble or reach your desired FSB.

when you run into trouble:
increase vcore as needed, but keep an eye on temps (make sure you're using speedfan or something that can detect core temps)
around 1400-1500 (350) you may have to increase NB voltage to 1.5x (I had to go to 1.7x to get stable at 1550).

once you reach your desired FSB/clock speed, test orthos for 6-8 hours!

you might also want to see if you can stay stable with RAM set to 1T.

Thanks a lot for the step by step instructions…I really do need them..(noob)
I also thought about lower the multiplier to x8 as you suggested but was unsure of this
as I thought I have read somewhere that lowering your multiplier is not good to do but don’t remember why??

Do you think it’s really not going to be that big of a difference performance wise running my ram at 667 MHz verse 800 MHz?
I figure I might get some really tight timings with my ram at 667 MHz…

Pink - RAM slot issue was only with stock BIOS
If you are still on it, use the 2nd slots.

Ravin- strange you get all those smileys and I get such a small amount?

XLR8- If you can get a lower multi, I believe it's actually better? Sync mode is 1:1 as Kopi said. Use that. Tribeca said AUTO but use sync. AUTO will keep your FSB/RAM linked, which is bad because it will constantly run a 1:2 divider due to the BIOS displaying QDR and DDR values.

There is a minor difference in performance running ram @ full speed vs 1:1. It will gain you maybe 100 points in 3DMark06. At best, I believe.

If you can lower your multi to 8 and run 375FSB that will gain you exactly 3Ghz, you can go higher and higher

Also you mentioned 333FSB x 9, 2997Mhz. Use 334FSB x 9 if you go with the 9 divider, and push it gently over 3Ghz (3006Mhz)

3006 is a much prettier number than 2997 hehe
