Asus P5E3 Premium Wi-fi-AP

[nick2006]

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.

Just try the way I did..

Using latest bios (0401), put everything in AUTO except the memory speed, timings and voltage. Set the speed at 1800 and use the stock timings and voltage values (in my cellshock pc14400 case 8-7-6-21 and 1.90V) and reboot..

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 ?? No memory in two pairs can give more than 1600Mhz ??? 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..

In any case, if you visit the asus forum for this mobo you'll find out that I'M NOT THE ONLY ONE with 4x1GB 1800Mhz modules installed !!!! Sorry but IMO the tech guy was giving you crap info, just to cover asus dirty laundry for this board.

I am too hoping for a new bios update, only for o/c reasons, since my ram is desperately crying for more !!!!
