In the manual, the 2 slot listings for 1600 and 1800 are for XMP DIMM installation recommendations. I hope that things will work out as wished. We should find out soon though. I also have P5E3 premium and QX9770 but unfortunately the 4x1gb will have to wait a bit (mobo being RMAed). Puttz, let us know how things turn out after you get things up and running.
What's wrong with your board?Quote:

I must admit that only with a new BIOS I could have any o/c hopes with this board...
Well, I've been able to boot this board with 4x 1GB of OCZ DDR3-1800 [running at 1600 with timings of 7-7-7-21 and voltage @ 1.90]; but as soon as Windows comes to the login screen it freezes. So far the highest clock I've been able to obtain using 4 sticks of RAM has been 1350Mhz with timings of 6-6-6-18 at 1.90v. I have not tried with just 2 sticks because I want to be able to use all 4 sticks. For now, I am content with being able to boot my PC at 450FSB and 1350Mhz on the RAM. I did a 32M calculation in SuperPI, but didn't have time to run it on OCCT yet. The PC is running on air cooling at the moment, but once I get it to where I want it and stablelize it, I will install the water cooling loop.
If anyone needs to know, my setup is:
Intel Q9450 running at 3.6GHz [vCore @ 1.20v on BIOS/1.168v on CPU-Z and OCCT; PLL @ 1.50v; FSB Termination @ 1.25v; NB @ 1.25v; SB @ 1.05v; everything else was left at AUTO]
OCZ DDR3-1800 Platinum Edition 1GB x 4 running at 1350Mhz [6-6-6-18, 1.90v]
I will mess around with it some more tonight; maybe try it with just 2 RAM sticks and see if I can get it to run at 450FSB and DDR3-1800. I know the RAM is capable of doing DDR3-2000, but I will not try that until I'm confortable with a stable 425-450FSB so that I can then install my water cooling loop on it.
I'm able to run 4x1GB Crucial Ballistix DDR3-1600 memories at 1600 7-7-7-18 1.80V on my P5K3 Deluxe. So ever P35 chipset can support 4x1GB memories at 1600 CL7. I don't see why X38/X48 chipset cannot run 4x1GB at 1600.
My origional question was though, what if any of the mid ranged speeds of DDR1600 are overclocking to DDR1800~2000? You know, just like when early DDR2 533 was overclocking to 830MHz? Also, is the 2x 2g holding anybody back compared to trusted 2x 1g @ same speed and OC?
Just try the way I did..Quote:

I use the QX9650 (3.000Mhz) and the bios auto-overclocked it at 3.150Mhz using 1.312V (according to cpu-z).
The important thing is that ALL modules are working fine under Vista x64 (put them under stress using the iso image of memtest with success) at these settings and - MOST IMPORTANT - all are running at 1800Mhz !!!
Just try it... :)
In my case, if I follow those steps I can't even boot into Windows at 1600FSB. If you read page 2-14 of the manual, it states that my particular memory is not supported in dual DDR mode [2 pairs] at any speed above 1333Mhz. Now, I was able to get it to boot with all 4GBs because 1350 and 1333Mhz are so close to eachother that it probably it didn't notice. Anyone that purchased the OCZ DDR3-1800 Plats is on the same boat as me; we are just going to have to wait it out until ASUS kicks out yet another BIOS revision aimed a memory support. I even spoke with ASUS tech support and they told me that as of now [that they have heard of] no memory is capable of running 2 pairs at anything above 1600Mhz; he told me that the only memory capable of stable boot into Windows at 1600 is the Corsair Dominators [same model from the manual]. The thing that scared me was that he told me my particular RAM is not even supported for regular DDR mode at any speed above 1600, that I will be stuck with using just ONE stick.
Am I from outer space or what ?? :eek: No memory in two pairs can give more than 1600Mhz ??? :eek: I happen to use THAT kind of formation and nothing bad is happening... I'm sorry though to hear that your ram brand is giving you headaches..Quote:

I am too hoping for a new bios update, only for o/c reasons, since my ram is desperately crying for more !!!! :shock2:
I have had a terrible time with any adjustment of DRAM frequency. Memory checks out ok. After any change at all (not even to oc speed) I cannot post and will have to manually restart (then automatically stops and restarts twice) then will give overclocked failed message. So after talking with several techs the suggestion was that mobo was faulty which I suspect is the case (psu not the issue = ultrax3 1000w). I will be at 2 sticks 1600 until new mobo arrives and will then try to join the oc crowd.:)Quote:

No problems with ram clocks. managed 2100mhz 8-8-8-21 fairly easy and can get some really nice bandwidth with tight PL6 450fsb DDR3-1800 7-7-7-18
Unfortunately I am using a 1mb (!) S3 Virge PCI video card and can't test 3D until GT200 and RV770 come out.
Nice board :up:
Things seem to be looking up! :up: I was able to run it at 400FSB, and the RAM is running at 1600Mhz with all 4 sticks. Timings are set to a mere 7-7-7-21 with 1.94v [this RAM supports a max of 2.0v before the warranty is voided out]. As far as system voltage, I got the CPU @ 1.20, the PLL @ 1.50, the termination at @ 1.10, DRAM @ 1.94, NB @ 1.35, SB @ 1.05. I'm happy with those voltages, except for the NB one; does anyone think its a bit high at 1.35v? :confused: Please advise.
PS: I had it running from 12am til 7am this morning on Prime95. Had no errors whatsoever. :yepp:
You should have no problems at all at 1.35 Many with this board are running higher than that with no problems. You are quite safe 24/7 at 1.35 and could safely go higher if needed.Quote:

I'm looking for reasonable OC vcore for up to 480FSB.
Intel Penryn Q9450 step SLAWR (C1), batch # L803B524
Thanx!
For everyone to know.
I had multiple errors with memtest86+, always at address '00000000000 - 0.0MB'.
I disabled USB Legacy in BIOS and the errors vanished.
It seems to be a known trick but I think its great to mention it again in this thread.
I run bios (0401) btw.
I don't have a q9450 but here's my numbers from a xeon@4.05g, bios 204, ram is ocz flex ddr3-1600...Quote:

twister at lighter... static disabled..
PL at auto = probably high...9ish or soo..
why this settings? probably the worst performance ever...why even have this board? hehe..
ok now im beeing harsch....
Heads up!!
new bios
ftp://ftp.asus.com/pub/ASUS/mb/socke...emium-0402.zip
no changelog, some one want to try?
[ 0402 ]
----------------------
Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx.
That is not recommended if you have a USB keyboard. Which bios are you using?Quote:

when it boots and it asks if i want to start with usual settings....and i went... WTF?!! batteries dead or what?
started to pull out the cord...struggeling with this....hehe.. then a light hit me!
btw it were someone that said that disabling this helped OC ... well...... not really?
Good, maybe you can make me some crash free suggestions?Quote:

I think I had the confirmation that the errors 'memtest86+ fails at address 0.0MB' were due to a bios bug rather than my RAM sticks.
Give us some useful tips brother...Quote:

I use an air-cooled (Mugen) intel QX9650 with Cellshock 1800Mhz 8-7-6-21 at 1.9V (Micron D9GTR) ... can I drop safely to... what value ???
Any help MOST WELCOME !!!!! :)
In ASUS Forum they say that the 0402 bios is MORE STABLE than the 0401 !!!!Quote:
