Asus P5AD2 Premium and 5400s

[[Excalibur]]

I suggest you to buy a PSU 24 pin ATX 2.0 compatible.
Using a 20 pin connector is possible, but not recommendable: don't save money for PSU on this system... it's a non-sense to spend a lot of money to build a system like this and economize on the power.

And there are a lot of noiseless PSU: for example, u can't hear my Enermax at 10 cm even if fans are running at full speed.

[eran_wolf]

Ok, so after the same issue I was having as everyone else with the machine locking up in games, I sprung and bought an Enermax 600W SLi compatible PSU. More than enough juice for this rig. However, just last night my machine locked up in World of Warcraft twice. Now this game isn't a slouch in the graphics department, but its no Half Life 2. Also, when I say locked up, I mean the system just freezes. The graphics on the screen just stop the USB ports turn off (I can tell cause the lights go out on the keyboard and mouse). The only way to do anything at this point is to hit the reset button. The killer is that nothing is even going on, on the screen thats that graphically intensive.

I have even run 3dMark 03 and 05 to see if I could reproduce it under a heavy load and nothing. It won't do. The only times it has done it is in WoW.

I am truly stummped. I will gladly entertain all suggestions.

[Yellowbeard]

See if you can get some other program to cause this freeze. I'd suggest Prime95 and then perhaps a game on top of that or Prime95+1 of your benchmark utilities listed below. However....

I have even run 3dMark 03 and 05 to see if I could reproduce it under a heavy load and nothing. It won't do. The only times it has done it is in WoW.

I'm guessing that this may be a driver issue or a game bug since you have upgraded to an excellent PSU. Also, I did not read above to see your complete system spex. Can you attach them to your signature?

Good luck, Mike.

[eran_wolf]

My system specs are in the signature. Also I have no temp issues as far as I can tell. Even when I hammer the system in 3DMark the Cpu tem never goes above 45C and HDD 30C.

Eran, just to satisfy my curiosity and to eliminate a variable, try your gaming again with only 2 sticks of the PC5400. 2gb of RAM is a very heavy chipset load.

Good luck, Mike.

Ok, so now I was burning a DVD last night and it just locked up, twice. At that point I really started digging in the BIOS. I noticed that there is a setting for Intel Speed Stepping. Why is there a Speed Stepping setting on a desktop board. Anyway, I turned it off and haven't crashed yet. I am not going to say its fixed but I played WoW last night for about 2 hours and burnt a DVD and it didn't crash. Knock on wood. I am throughly going to test it tonight and will post the results here.

That IS bizarre I hope that resolves the issue. Let us know, you may have stumbled onto something that other users and mebbe even ASUS need to be made aware of.

Mike.

[eran_wolf]

Ok, I had ran the memtest and all showed ok. I have also run driver cleaner and updated all drivers. I played WoW for about 3 hours last night and no lockups. I have also burned 2 DVD's. I still am not going to say alls well, but I am begining to thing that the Intel Speed Stepping feature was the problem. I still for the life of me do not know why an Intel Speed Stepping setting is in the BIOS of a desktop board and the feature is enabled by default. I will write o
n3 here if anything changes.

Unless there is some benefit to using speedstep for power saving or sumpin, that is VERY odd. I "know some people that know some people" and I'll see what the scoop is on that being on a desktop model.

I'll keep my fingers crossed for you. Mike.

Eran_wolf, could u please specify where this setting is located in BIOS and how is it called by ASUS? Thx.

[eran_wolf]

It is in the Advanced Chipset settings.

It is not hidden but easily missed because you have to scroll down in the menu to see it.

It's been 3 days now and no lock ups. I am begining to think that was it.

Eran_wolf, i still can't find what u're talking about. Pheraps u're confusing it with Hyper Threading Technology in Advanced -> CPU?
Anyway, my menu Advanced->Chipset is so structured:

Configure DRAM Timing by SPD
DRAM CAS# Latency
DRAM RAS# Precharge
DRAM RAS# to CAS# Delay
DRAM RAS# Activate to Precharge
DRAM Write Recovery Time
DRAM ECC Mode
Hyper Path 2
Booting Graphic Adapter Priority
PEG Buffer Lenght
Link Latency
PEG Root Control
PEG Link Mode
Slot Power

And that's all. No trace of your "Speed Stepping"... are u using a non-standard-BIOS?

[Yellowbeard]

I wonder if the speed stepping deal only shows up with 6xx CPUs? And, are both of you 2 running the same bios?

Mike.

[[Excalibur]]

BIOS 1004 here.
I suppose u're right, SpecMike, it seems that EIST (Enhanced Intel Speed Step) is supported only by the new 64-bit 6xx series.

That's right. 6xx serie supports speed step-none other. Cool&Quiet is ounterpart on AMD's side

Eran Wolf, will your bios still allow you to manually select the 14x mulitplier? I have an ABIT Fatal1ty now and an P4 650 and I cannot select the multi. Also, I have the option to disable Speed Step (aka - EIST) and it shows disabled in the bios but, it is actually still functioning.

Thanks, Mike

Ok you guys are scaring me now I just ordered this board (ASUS P5AD2-E Premium ATX Intel Motherboard)
and the exact same memory (CM2X512-5400C4PRO 512MB PC5400 667MHz XMS2 DDR2 240Pin)

Did you have to overclock the cpu voltage or did it autosence?

I ‘m just wondering if I would need to just go with the standard

Corsair VS1GBKIT533D2 1GB Kit DDR2-533 PC2-4200

And return the 5400 memory before its too late

I really want to eliminate any bottle neck as much as possible.

Are you guys still having these issues with your current config?

If not what was the fix ?

The RAM runs fine with this MOBO. It is a simple selection in the bios to choose either multiplier. Then, you would need to manually set the desired FSB and RAM speeds.

I'm not sure what specifically your concerns are. This is an older thread. However, long story short, I have this MOBO and RAM with an Intel 650. I have also run a 550 and a 630 in it. The ASUS runs great.

Mike.

it seems that some issues observed in the previous pages of this thread regard the critical tuning of the North Bridge I925X (4x200MHz) or I925XE (4x266MHz).
It's known that North Bridge chip is responsible of the connection between most important heart-part of your system: CPU (via FSB), RAM (via RAMbus), PCI-express bus, South Bridge (for peripherals).

Well, it's true that all of you have talked about CPU and RAM settings, but NOBODY about PCI-express frequency.
There's a little trick from ASUS: in these mobos, "PCI express frequency" set to AUTO sucks. Why?
Designed for overclocking applications, the default setting AUTO seems to be NOT the regular value FSB / 2 (at defaults PCI-e frequency should be generated from the same PLL that drives the FSB quad-pumped, the so-called TO CPU synchro in BIOS: so, if PLL freq is 200MHz, we obtain 800 MHz for FSB and 100MHz for PCI-express), but seems to be, instead, slightly LESS.
Of course, some PCI-e video cards suffers about under-clocked buses (ATI Radeon in particular. Note that it's not an ATI issue, it's an ASUS trick!), and can generate black screen, BSOD (blue screen of death), restart of the system 'cause instability between data on PCI-e and North Bridge.

So, if you have strange instability issues on P5AD2 and P5AD2-E, try to disregard AUTO setting on PCI-express frequency. Set it to a manual value between 102-105 MHz for non-overclocked systems, and PEG Link Mode to SLOW (i.e. simply not try to boost communications between PCI-e bus and North Bridge, but only use freq. specified).

It's also true that if you overclock the system, you MUST increase manually this PCI-express frequency, too. Or North Bridge will suffer of some kind of arbitration loss of data. Values between 105 and 110 MHz for overclocked systems should run well.

Hi,

I have putting together almost the same configuration as most people on this thread, primarely for video editing and graphics, after carefully reading up on corsairs super xms2 5400 memory I finally decided to place my order. Purerly by chance I reached this forum only to have found out that their are severe compatibilty issues between asus p5-ad2 mobo, p4 3.4 and the TWIN2X1024-5400C4 memory. Is this true? Am I to be the unlucky owner of a workstation with issues?? The TWIN2X1024-5400C4 is sadly not obtainable in poland, as are many other goodies, so I am making a big effort to acuire the items I believe(d) to be fairly top notch.

Should I cancell my order immediately ??

Any info will be highly appreciated !!!

Thanks, zzmster

Asus P5-AD2 Premium

TWIN2X1024-5400C4 ( awaiting arrival )

I tried all memory settings, memtest86 and everything else. I am completely out of options, but I think ASUS might be holding back on us with this. I mounted to case fans directly above my processor for additional air flow and have a CPU temp of around 45 when idle and as high as 68 when under extreme load. I have tried all kinds of thermal past and stock cooling with both processors and can tell you that tom's hardware article about intel P5-560s heat can crash and kill is not correct in their point that intel thermal paste is cooler than artic silver 5. It depends on how you apply it and if you know what you are doing you definately will do better with 3rd party thermal paste. I have latest bios, drivers, windows updates, etc but this configuration will not work. Also to note that I ran a CPU non graphic intense program mentioned in the tom's hardware article(prime95) and after about 40 minutes it also crashed the system. Last noted CPU temp was 68. All I can say is that I really wish I had gone with AMD. Even if it is a temp problem I do not know what else I can do. I go from 45 idle to crashing in Unreal in under 60 seconds sometimes

All I can say is that this configuration will not work

Intel 3.4 GHz(replaced once and still have same problem)
Asus P5AD2 Premium(replaced once and still have same problem)
Asus ATI X800 XT PE(also hand same problems using Powercolor X800 XT)
Thermaltake Butterfly Purepower 480W w/Active PFC(also tried one without PFC)
2 10k RPM Raptor SATA HD(Raid 0)
2 7200 RPM WD EIDE HD(RAID 0)
Thermaltake Viking case with 2 side mounted fans over processor

If anyone has any systems that have any combination of 2 of these parts working together fine and can play high end games please email me at dheim@comcast.net or drheim@hotmail.com

Right, 33.33 MHz is the correct freq to fix the PCI bus.

Doesn't care, leave them to auto. The only trick to remember is to set PEG Link Mode on [SLOW].

I've pushed these rams to DDR769 (dual channel, mem freq=384.6MHz) with timings 4-4-3-8, FSB freq=288.5 MHz, second DRAM frequency memory selector (multi FSB : DRAM=3:4). As always the third selector (2:3, that is 600 MHz for 200 MHz FSB) has NEVER worked, but this is a known issue.

I've read through the forum and I've noted a few BIOS tweaks to try. Could someone who understands all the intricacies mind posting a complete list of recommended BIOS settings for the P5AD2 and Corsair XMS 5400?
What I've seen so far is:
Set PCI-Express Frequency between 102-105 (non-overclocked)
Set PEG to SLOW (by default many motherboards try to overclock and this causes issues)
Set the PCI Bus Freq to 33.33

Anything else I'm missing?

[CandyKid]

I have a P5AD2-E Premium Wireless Edition and have previously used Twin2X1024-5400C4PRO's in it without trouble.

I have overclocked my 550J (3.4GHz) to a 222/888 FSB so that DDR-II 667 is selectable in the BIOS.

When running these modules, the PEG was set to AUTO, the only things I changed were the latencies and the DDR Voltage. The speed-step (the 550 runs at 14x when not being stressed) is ON and the PCI-Express frequency is also AUTO.

Right now, I'm running the same setup with 4 x CM2X512-5400UL's at DDR-II 667 and 2.1 volts. Those are the ONLY manually set timings other than the FSB and memory frequency. Everything runs just fine as far as I can tell, passes Memtest86+, runs Super Pi to 1M digits with a correct checksum, etc.

Make sure you've got very good cooling in your case as that was my only downfall, but the installation of water cooling quickly fixed it (CPU, chipset, and GPU).

The manual of your motherboard states that you need an atx2.x PSU
or have at least 21A on the 12V-line. (8A on the +12V_1 plus 13A on the +12V_2)

No matter what make or type of PSU you choose, make sure you have 22A at hand on the +12V_2-line. (I don't trust manufacturers who don't give detailed tach specs about their products)

Good luck!

hi

where in the manual ? i never seen that !!
never seen 21A for the 12 V in the manual of p5ad2-premium , have u a link ?
my psu is not good for my motherboard ??
22a to 18a is very important ???
