P5AD2-E Premium & Corsair 2x512 pc5400 TwinX, good or bad idea ???

I have heared that this mobo and this memory doesn't really "like" each other... is it right ???
Any problems with that "mary" ???
Any bad issues ???

Please help me because I"m thinking of buying this stuff...

Thanks,

Doesn't anybody know anything about that ???
May I buy this motherboard with this memory without any problem ???

never heard of pc5400 unless your talking ddr2. a64s do not support ddr2, but you cant go wrong with most tccd ram :) However you gotta hope you got a good ondie controller if you want 1:1

Hummm...
ASUS P5AD2-E Premium motherboard is not for A64... it's for P4 LGA 775...

I have the combo you describe in your topic and my system is rebooting @ 4.0 ghz whenever i put some load on it. i thought it was the mobo but now i think its cos of the powersupply. Im getting a new power supply unit on monday with the 24pins plug instead of the 20 pins that should fix my problem hopefully.

Very good news you're giving me !!!
I know for you these news may not have been as good as that bur for me it's really a good news, because I have ordered this bundle and I was beginning to become sad with that situation, thinking that I haven't made a good choice...

I got the 24 pins Tagan 480 watt psu and its still unstable :(
so its deffinately the instability problems between corsair memory and asus mobo :(

I have the P5AD2-E Premium and Corsair TWIN2X1024-5400C4PRO with horrible problems!

Firstly, my CPU throttles when I overclock (from ~2,8 to about 3,2-3,3) (checking with Panopsys ThrottleWatch, http://www.panopsys.com/throttlewatch.htm). My IDLE temp is 55C with an 7700CU and its mouted as it should be!

Secondly, my FSB jumps up and down from about 100 MHz to whatever I set in BIOS, very very strange. The POST also take very long time, the computer looks for harddrives for about 1 minute until it continues to boot.

I cant get the WiFi to work, I get "Unable to connect to the wireless lan card. The tray icon will be loaded once the card is inserted" when I try sto configure the WiFi. The funny however is that I can see the icon down in the systray, and in the device manager I can see the device and the drivers seems to be installed fine.

My other hardware,

P4 2,8GHz (D0-stepping)
PowerColor X800XT PCIe
Maxtor Diamondmax 300GB SATA
Bios 1003b7
Plextor 712SA

Well, don't buy this motherboard, I'm going back to my old Gigabyte 915P...

Corsair can suck my balls i just ordered Crucial Ballistix DDR2

Installed my old Gigabyte 8GPNXP Duo and everything works fine. Nor do I have any problems with ABIT AA8XE Fatal1ty or Gigabyte 8AENXP-D. So personally I think the problem is with ASUS, not Corsair.

So ASUS is the one who can suck my balls! ;)

Operator Headspace.....is your problem....Not ASUS
I ran into similar problems but I was able to work them out on my own and no longer have any problems what so ever....
Maybe a bit more patience and tinkering will get you out on top.....
Try reflashing the bios,
Instead of using the ASUS WiFi drivers...use Microsofts more updated drivers through windows update....for both the Wifi and the LAN....
Learn your bios....!!!!
Your problems are not difficult to fix....


SKI

yeah what djski said. yours has nothing to do with the Asus mobo and Corsair ram.

I dont have problems with Corsair on stock speeds either, works perfect.
However at 4.0 ghz its giving me problems thats why im changing to Crucial :X it should work perfect then. I'll keep you people updated.

Well, if they are so simple to fix, why can nobody that I've talked to help me? I've been in contact with ASUS R&D i Taiwan and Holland, I've gotten tons of different BIOSes (latest from 23/12), and I get the same symptoms with all of them.

Yes, more patience, I've spent roughly 50+ hours to try to get this board working… Took my old Gigabyte, plugged it in, after 5 minutes of work it was up an running without any problems… My personal opinion is that no board should take this long to set up, no matter what.

My personally opinion is that either is my board defect (the most probable cause), or ASUS have release a half finished product.

And if you have sorted out similar problems, could you please describe how you managed to do that?

can you please mail me that latest bios to corleonee@gmail.com.
I'd really REALLY appreciate it m8 thanks in advance ! :toast:

Asus P5AD2 Premium and 5400s

Some interesting things have come out of that thread, which Ram Guy (Corsair's official rep) stickied in their forums:

The computer would run fine for days, but would turn off after about 5 minutes into playing any game. Thought it was a heat issue for a long time and kept reapplying different thermal pastes with no luck in fixing problem. I had tried every single setting imaginable in the BIOS and still would not works after hundreds of attempts until I replaced the PSU.

So far there's 2 or 3 posters there that have switched to different PSUs and that's cleared up their problems. Nowhere near enough to say for sure that that specific PSU is the problem (could be just coincidence), however if you have a spare PSU that's hefty enough for it, it may be worth a quick swap to test it.

The one that worked best thogh was the Enermax EG701 600W. I got the board to where the only bug left was that it would boot uncommanded in response to network activity even though "boot on LAN" was disabled in BIOS.

The first P5AD2 went back and the second one would boot and go into bios fine, but it never even made it into Windows once. It too went back and I put in an Intel D925XCV and lived happily ever after, although without Firewire 800 and some other cool features. I have read numerous messages on forums from those having trouble, and was told that Asus revised the P4AD2 and that the new rev is working fine. If you are having trouble, make certain you determine if you have the most recent rev board. Very disappointing, best of luck to you all.

Also, are you guys underclocking the memory to match the system's FSB, or running it async, or just straight trying to bump up the FSB to the speed of the memory?

Sorry mate, I'm not allowed to forward it, the latest you can get as of now are the 1003b7 (which you probably already know).

And I'm using a Antec Neopower 480W (regardin the post above with PSU issues). Will try with a TruePower 550W and Phantom 350W tomorrow.

Hey nicenzo i found the solution to your problems however its confidential.
sorry

pfff SS'er

I got the Crucial Ballistix and i am now rockstable @ 4.1 GHZ !
With the corsair i couldnt go stable over 3.9 ghz :S

Hardocp has a review on the Asus P5AD2-E + Corsair ram. They couldnt get it stable over 3.9 ghz either

I have 1gb of OCZ PC4300 3-2-2-8 Platinum and I'm having issues with it posting properly and running stable. Asus suggested that I buy different memory for my P5AD2-E. :)

I'd say 60% of the time when my system posts, it hangs right after it displays the memory count. Or it proceeds to operate extremely slowly and will misdetect the drives in my RAID0 array.

They offered me no bios updates, nothing to change. Simply to get different memory. I know it's not Corsair, but I'm kind of in the same boat with some of the best DDR2 on the market.

i've have this mobo and 2x512mb ocz pc2 5400 4-4-4-8, and i don't have any problems...

Hummm,I was thinking of getting the mushkin pack 2x512 pc5300 along with this MOBO, does anyone know of any issues regarding this 2 components? After reading this thread I got a little "scared" oh this MOBO...

With the latest Beta Bios Version 1003.011 does the momory situation looks better ???
Can anybody with Corsair memory test it ???

Would be easier if you all posted your exact setting (dual cpu-z screenie sure would be of some help).

I don't have an E-version of the board but I experienced strange things...
The weirdest thing was that at 4-5-5-15 timings, I couldn't overclock...
i560/P5AD2 Premium/X800XT/Corsair TWIN2X512-5400C4 - combi

So I first switched to fsb200/DDR600 and tightened the timings (2.1V vDimm)...
4-4-3-11 gave me best performance (memtest and Everest)...
After that, I switched to fsb200/DDR533...
Upped the fsb somewhat and this is what I've got with the memory people here seem to hate:
fsb 233 / DDR622
--> rockstable, running 2*f@h 100% 24/7, after two days, cpu is still not throttling...

Actually, I was thinking to get me the E-version and some OCZ-sticks, but will it help me that much?
Or is it simply the guys at ASUS who are not doing their homework???

btw, I'm using bios 1010.004 beta on this P5AD2 Premium...

@DJ_SKY69: could you post some working links in your signature (3Dmark-stuff, I'd like to see the settings you used :toast: )

Hi!

My System: P5AD2-E Premium 1003 Bios, Intel 560j 3,60 GHz @ 3,90 GHz, 2x Corsair TwinX 5400C4 1024 MB runnig with FSB 278 Ram 576 4-3-3-8 Timings and 1.90 Volt. With 2.10 Volt and 4-4-4-12 I can get the Corsair stable at about 710 MHz, but cant run the board with a higher FSB than 256 and use the 3:4 divider. The board sets the ram timings to 4-4-3-8 all the time.

Hope this helps?!

Thuroughly tested P5AD2-E and Corsair 5400XMS PRO

1002 and 1003 bios up to 2.2v DDR780 or so

This combo works fine

Oh that's nice! I think the 1024 MB Modules are holding me back!! :rolleyes:

Finally testing system: 4,5Ghz but 4,4Ghz rock stable...
Can't pass 700Mhz with the Corsair at this time, 4-4-4-12 and 2.0v...

I've been testing and now I can achieve 315x14,
With the Corsair 3:4 840Mhz at 4-4-4-12-4 with 2,1v,
This is rock stable but I think I can go a little higher...

I'm using these voltages:
Chipset Core Voltage: 1,75v
CPU Vcore Voltage: 1,5000v
FSB Termination Voltage: 1,45v

Do you think it's too much for 24/7 ???


I'm going on testing...

I can show some screenshots of my actual results,
I noticed than going higher than 316x14 with the 3:4 memory divider, the bandwith begins dropping down so I think I will stay at 316:

At 316x14 we can see:

http://www.cyclopnet.pt/~nsl69249/316Sandra1.Jpg

http://www.cyclopnet.pt/~nsl69249/316Sandra2.Jpg

At 317x14 we can see:

http://www.cyclopnet.pt/~nsl69249/317Sandra1.Jpg

And at 318x14 we can see:

http://www.cyclopnet.pt/~nsl69249/318Sandra1.Jpg

what about 1:1?

You mean 316x14 with 1:1 instead of 3:4 ???
I can try...
But do you think I will get more memory bandwith ???

I meant that see if bandwidth drops at 317mhz FSB with the 1:1 divider
You may also try to get low latencies at 1:1 - may yield even greater bandwidth.
