i dont see why not long as you power supply is good nuff
Yes, you are right. The reason I asked because when I shutdown or turn on the power for my computer ...it come up with the sound...then I chked out their website they said...I need bigger Power supply. My PW is 500W . I guess time to upgrade my power supply. Thank you for your help.:clap: :clap:
no problem always glad to help

RAID 0 with 3 disks? I think you need multiples of 2 disks for RAID 0. RAID 5 uses 3 disks (or multiples thereof). Also, the performance increase when going from 2 x RAID 0 to 4 x RAID 0 is minimal (I was considering the same myself until I saw the figures). Can't remember where I saw this comparison, but if I find it I'll post a link.Quote:

Saying that, I haven't tried removing the jumper.
hey Guys,
what the temp you have on your mb measured in sandra? I am getting about 50 Celsius, is that ok or is it too high?
cpu temp is about 28c.
thanks
...and one more thing: has any of you had problem during startup when all lights are on, but there is no post? computer just stops, all you can see is hd working and hear all fans. that's it. nothing else. it's worth mentioning that I haven't changed anything in bios. usually, I have to reset cmos and leave it unplugged from the power for about 10 to 15 mins. then it works fine pc is booting up.
is the motherboard faulty? I just bought it last Sunday and think that I should exchange it. also, which other mb from asus would you recommend? or maybe I should stick to p5w?
thank you
What cpu and heatsink do you have ? Is it overclocked (I guess not if you haven't changed any BIOS settings as you say in your next post) ? What's you're ambient temp ? Does the case have good ventilation ?Quote:

RAID0 you can use 2,3 or 4 disks. "Minimal" performance increase is subjective. I've seen the benchies too and 180MB/sec throughput compared to 260MB/sec is plenty to justify the price I paid for this cheap used 740ADFD from a friend.Quote:

as I said, no tweaks were done in bios. didn't want to do it as I had the issue described in my second post.
what about my second question? did anyone experience any similar issue?
With the standard intel heatsink, you'll have air being blown onto the area around the NB. However, with only 1 fan exhausting air from the case and no intake fans, airflow through the case could be a problem and you could get a build up of heat inside the case. Are you able to add any additional fans to the case (intake on front, for example). Which case do you have?
To measure ambient, it's best to use an external thermometer (the ambient we want is the room temp). Any reading of 'ambient' from software will only measure from a sensor inside the case (which means it will be case temp). I wouldn't trust that reading from Sandra.
No ideas spring to mind regarding your 2nd post.
well,yeah, I think I will exchange mb then :/ I don't really want to reset cmos every morning:/ besides, that's a bit unacceptable for me to pay 100pounds for mb and experience such issue...
thank you for suggestions with the fan. I'll see what I can do
Curious on your results! :)Quote:

2) The CPU is a E4300 @ 3.6ghz, should I consider upgrading it to a Q6600/E6850 while still having this 975x mobo?
Help out a noob in need :)
TIA
well the quad seems to be the future thats for sure this board will run it be sure to get the go stepping and you will have to up date your bios for that to 2302 i think it is or lawys modded bios on the first page
Rich
I've heard the P35 chipset is a much better/stable chipset to OC the quads.
yes it may but this board dose ok with quads maybe not as good as p35s but ok
Rich
This motherboard is stable with quads as long as you want only a moderate overclock. My 3Ghz Q6600 is really stable and I'm very satisfied with stability and performance. No reason to upgrade motherboard or overclock higher for me really.Quote:

Any truth to the fact that the P5W DH does not OC well with 4 sticks of RAM and the the P35 chipset (i.e. P5K DLX) handles 4 sticks much better?
Yes I'm an idiot and the board is still bullet proof!:)
The ICH7R IDE problem I had was really annoying me so I removed the motherboard and found the center pin on the IDE connector was pushed back very slightly. I didn't notice this when checking the pins as I had left the motherboard in my case and it looked fine. Pushed it back to normal position and I can use the ICH7R ide again. Although the Jmicron has been working fine for me the last few days.
That's the last time I try and check the IDE connector with the board still in the case.
P35 is better at clocking memory from the start than 975x. Both motherboards clock lower with 4GB than 2GB. That's all.
So obviously P35 is better with 4GB than 975x is with 4GB, old news.
this board has been so good to me i have a hard time thinking about up grading i guess it will end up my back up cuz im not selling it :p:
My overclocking wasn't affected by the RAM, I had my E6600 OC'd from 2.6 GHz to 3.1 GHz, only the RAM speed was an issue. I had 4x1 GB sticks in this board and was only able to run the at PC2-6400 speeds. I picked up an Asus Maximus Formula and can run the same RAM at PC2-8500 speeds.Quote:

That's exactly why I went with 4gb's.... ;)Quote:

I can't turn the memory remap feature on as my OS (Vista) is only 32 bit. And with the remap disabled, the motherboard is appropriating 1.53 gig for my 2 graphics cards.
So only 2.5 shows up in Windows.

1 x 2 headed ATI Radeon X1300 - 2 x 256m heads = 512
Totaled up: 1536 Meg appropriated and unavailable to any OS.
Vista shows 2560 meg RAM.
If I enable the memory remap feature, the BIOS shows 0 appropriated, 4096 available to OS, but Vista 32 bit shows 2048 meg only.
Burner27 said in this thread that when he had BIOS version 1101 installed, it didn't appropriate anything - but with the latest BIOS, it does.
I'm running the latest (2302)- and I am going to have to try each anterior version one by one until I get to one (hopefully before I get to anything as old as 1101) that doesn't appropriate any RAM to give my system a chance to see 3.2 gig of the 4.
It's frustrating - if it didn't have this RAM to appropriate when I only had 2 gig, why on earth would they code a BIOS that needs to knick my RAM just becuase I put MORE in? It makes no sense - more and more people are using dual graphics cards - and this board has two PCIe slots!!!
If the board didn't appropriate when I only had 2 gig RAM, then it doesn't NEED to, thus this appropriation is unecessary and wrong!
I don't suppose any of you happen to know from which BIOS version this started? Otherwise I'll be flashing my board about 25 times over the next few hours.....
Many thanks if you find the time to reply to this.

After much time and effort I noticed that u can only downgrade from Bios 22xx to 2004 using version 6.x of Asus update. Asus doesnīt know this apparently.
Anyway the Asus support send me Bios 2403.
Dear Valued ASUS Customer
Please try the attached BIOS which should contain a fix for your problem.
If it works or you notice anything wrong please give us feedback and we will look into it.
Best Regards

U might want it, the Onboard sound auto activation is fixed according to this guy as I asked about it.
I have NOT tested this bios myself and have no idea if itīs a beta bios.
Itīs not listed on asus website. Asus update confirms this bios is from Yesterday 8/11.
http://files.filefront.com/P5W+DH+AS.../fileinfo.html
Cool, waiting for the first experiences before I will try this bios myself. I'm getting annoyed by this auto onboard sound activation with 2302 :D
The first results from German forum 'forumdeluxx' are encouraging:
Users are reporting that Speedstep works again plus that it is again
possible to disable the onboard sound
http://www.forumdeluxx.de/forum/show...7&postcount=50
http://www.forumdeluxx.de/forum/show...0&postcount=61
Both in German; sufice to say, they're happy with it so far.
I'm using 2302 now and never noticed onboard audio turning on. How is this happening? Are you by chance going into the bios and see it as enabled or something else?
As far as I am concerned this MB is best used with the EXX00 series CPUs at 1066 FSB vs EXX50 CPUs at 1333 FSB when it comes to OC. With a E6700 OC'd 3.4 I could do 4:5 on the ram. With a E6850 OC 3.4 or 3.6 I can only do 1:1. The dram frequencies are so high in the BIOS you would need a 1333 Ram in order to get anything other then 1:1. Problem is, 1333 ram are only found in DDR3 not DDR2. The P35 or X38 is a perfect fit for the EXX50 series of CPUs at 1333 system bus while the P5W DH is a perfect fit for the 1066 CPUs.
This is the main difference between the aging 975 powerhouse vs P35 or X38. Over clocking capabilities will very from one chipset to the next however the most noted difference that matters most is that the P35 and X38 are designed to use 333 FSB CPUs that are entering the market.
If there is a way to set the FSB strap on a P5W DH to 333 I am all ears!
http://i11.photobucket.com/albums/a1...C_settings.jpg
In the pic above, the Dram Frequency is set to 800, not 1000
http://i11.photobucket.com/albums/a1...3_6_PC6400.jpg
This is the result of the bios settings using PC8500.
http://i11.photobucket.com/albums/a1...ck_Profile.jpg
http://i11.photobucket.com/albums/a1...rofile_3_0.jpg
In order for the Bios to recognize your E6750 or E6850, etc you have to use the Overclock Profile and select 1333/DDR2/884 or 667. Or else, it would downclock your E6750 or E6850 when booting up at standard clock. Also, this is from bios 2302. I read there is a 2403 (or something similar) but I haven't found it yet.
I'm noticing that dang onboard sound crap too. After every power off, then power on, the onboard audio is enabled again (visible in the BIOS.) 2302 needs to go NOW.
Where's 2303?
Trying 2403 now........
UPDATE:
This BIOS is safe (from links above) and the onboard audio problem is fixed! WOOT.
What onboard audio? How did you know onboard vs sound card was turned on? :shrug:Quote:

With the craptacular 2205, 2206, 2301 and 2302, the onboard audio plus the onboard serial would always reactivate themselves.
These bioses also had issues with Speedstep not working etc.
Apparently, the onboard-audio-bug would mostly happen to people who had the onboard audio switched to "off" before they were flashing 2205/2206/2301/2302.
That could also be a reason why Asus' bios writers didn't catch this bug.
Uh, I always had it switched off and it never switched itself on through all mentioned BIOSes. Weird.
This is how I updated as well. That's why I don't understand what's going on. One rule of thumb that I thought everyone knew is to go to default cpu and default ram settings before you update a bios. I wonder if that had anything to do with the problems some are having. :shrug:Quote:

OK, firstly, this is not a "made-up" bug.
It's funny how you're implying that people are making this up (although not quite
saying it out loud), while on the other hand, you're not making the slightest
attempt to read up on that bug on this particular thread.
There is a page counter to this thread, up on the right, you know. :rolleyes:
Secondly, DUH, certainly I (we, who were plagued by this bug) know how
to load setup defaults. :mad:
Remember just because you yourself weren't plagued by this bug does not mean that others weren't!
Just entering 2302 into the search function would have turned up this:

Hi guys.
As you may have seen from my post above on this page, I'm trying to flash my BIOS back to a much earlier one. The standard Asus DOS flash prog will let me regress a few versions but not to the one I believe I need. It says "the BIOS you are trying to flash to may not be compatible with this motherboard" Eh? They might be old, but they're all for this board. Don't get it.
I really need to do this as the damn BIOS is allowing the motherboard to 'appropriate' 1.6 gig of my 4 gig RAM, thus only allowing me 2.5 in windows. (All explained in my post above).
Is there a more powerful flash tool that I can try? The utility built into the bios system seems to be very buggy and slow; I used it once but wouldn't depend on it. DOS versions seem to be easier.
Many thanks!
Will
ps I know there's another thread within this thread about sound issues - did I post correctly by continuing in this thread rather than starting a fresh one? 258 pages of thread is about the longest I've ever seen....ta.
No. I always flash my bios with defaults loaded, then load defaults again after the flash. Then restart and enter settings, and trust me, this bug happens.. EIST stays Disabled and Onboard audio stays Enabled. Started on 2205 and 2302 had it too. Have not tested 2403 yet, can't really be bothered, systems working well right now.Quote:

edit: fux it, i'm installing it now..
edit: woot, sound problem fixed! Everything seems to be ok as well.
I don't want to create a whole new thread for this but I haven't been keeping up with the news lately and I've searched around but haven't found a definite answer:
Does anyone know for sure whether the P5W DH supports the new 45nm CPUs or not???
yes it will for sure with a updated bios 2403 i think it is
Rich
Confirmed or speculation?Quote:

With the 333 FSB and low multis I have no desire to run a 45nm CPU on this mobo. That would be a huge disappointment and a big step backwards using this mobo.Quote:

I updated bios to 2302 and the problem is gone.
This is probably something everybody else knows but me but it might be usefull for anyone struggling with the same problem who's just as stupid as i am. :D
The bios appears the same and the board is running fine.
The one thing i don't understand is that i can't find the realtek wireless connection in bios, not under onboard devices, where both gigabyte lan's are.
The wireless conection works fine but why is it not in bios?
What do you mean? Big step backwards from what?Quote:

The changes in the FSB and multi's in the new 45nm chips have created a difficult issue using the older and even newer mobos. To get an equivelant overclock on the new 45nm chips vs. the current 65nm chips is going to take HIGH FSB - far higher than the P5W will go.Quote:

Rich
1.85V MCH may need more then just fan cooling. However, to give you an idea I was able to get a 400 FSB OC for a E6850 @ 3.6 to post PC8500 (although it would auto reboot during XP bootup) at 1.75V. I assume 1.85V would make it more stable but I am not sure about cooling needed. Here take a look:Quote:

The reason why I post this is because at 1.65V MCH it would not post at all at Dram Frequency of 1000 MHz! However, this 1000MHz dram frequency is not stable.
i have my mch set at 1.75 also with a small fan on it feels cool to the touch but havent tryed 1.85
Rich
I alternate my fan between optimum and performance depending on the ambient temps. Because I got a high performance fan, on performance it really screams for such a small 40mm fan! But I haven't needed to go beyond 1.65V as of yet for MCH at 3.6 (E6850), PC6400 using PC8500 ram.Quote:

What I've found about OC'ing is that the cooler the NB the better the performance and lower the MCH voltage. I too had a E6700 OC 3.4 and only needed 1.65V for the MCH but I am using Delta FFB0412VHN 40x28mm. This fan creates 15.79 CFM @ 9500 RPM, 41.9 dBA. Although 15.79 CFM doesn't sound like much at 80mm or 120mm, at 40mm it's like a mini tornado IMO (from using my hand). This fan makes all the difference IMO.Quote:

Does this board have any problems with running 4 sticks/4 gigs of ram? If it has, someone please point out what bios is best and what to look after.I just ordered another pair of cellshock 1000 C4s and dunno if it was the right decision.
Thanks in advance.
I had to lower my RAM from 1:1 to 3:4 (top option) otherwise I can't even change the BIOS options without pulling a stick out.Quote:

I am running 4GB and 400FSB fine. Only 1.65 vMHC as well. My mems are only PC6400 though.
Latest bios btw.
Yea thats the info i found googling like crazy that mems run ok at 800mhz but anything above that is nearly impossible.
I guess then ill have to go for 800 3-3-3.
I just ordered an additional 2GB as well, I hope I won't have any problems. I'm currently running at 400x8 (1:1) with pretty loose timings.
yes up mch and memory volt a lil may help with 4 gb of ram
I didn't find where the extra memory speed was more important than the extra CPU speed, so I stuck with what worked at 410Mhz.Quote:

Adding 2 more sticks straight ruined my OC - I tried EVERYTHING and ended up having to drop my OC by 300MHz. Just going x64 Vista alone I lost 100MHz of stability.
that dont sound right sounds like somethings not setup right
Rich
2403 now official..
have you tryed this any change from the beta ?
Rich
Eastcoasthandle so they fixed the 4:5 problem?
Can you run now at 400FSB : 1000RAM???
That's really good news man.. I'll get some 2 x 2Gb G.SKILL kit tomorrow then..
Did a file comparison and it seems there is no change from the previous Beta.
thank you good to know havent used it yet but heard it works good for new chips
Rich
No, it's not stable at 1.75V MCH. I also read that the Maximus Formula doesn't either :shrug:Quote:

Gonna have to get a P5K-SE or something if i want to run my ram at 500mhz+ without spending money on mobo.

On week ago my machine start BSODs. Yesterday, a last BSOD cause my Windows installation to not boot anymore. After running chkdsk from another Win, 8 GB of corrupted data was found. So, I formated everything and start a new fresh Windows installation.
Now, I come back and Windows did not boot again. Suspecting from a hardware failure, I disconnect everything and began testing each hardware peace, one at time. Quickly I discovery a memory problem: from my 4 memory sticks, only one is working right now. If I install any of other 3 sticks, in any combination possible, the machine even boot.
I didn't have another machine to test theses memory sticks right now. But I'm not believing the memory could be the problem. The memory was running just 1:1 and with 2.1v, i.e., not overclocking, not overvoltaging, nothing which could damage theses sticks.
What could be happening?
I forgot to mention one more thing, an important one: the memory is actually configured as AUTO in the BIOS (also, everything else is now configured as AUTO). When posting, the screen show the memory as PC2-5300. But CPU-Z is telling me the memory is running at 400FSB (PC2-6400)!
Completely crazy, isn't?
I just put in the additional 2GB I had ordered and I couldn't get it to boot into Windows at 1:1.
I raised the memory voltage to 2.1v (not sure if I should push it further) and mch to 1.65 which is the max available setting with my current Bios.
Had to set it to 4:3 to boot. Any suggestions?
It will be a sad day if its true that Window 7 (or whatever they decide to call it) is release showing that 4 Gigs of ram is not required...per rumor.
However, from what I heard you have to increase the voltage on the ram and increase Mch. However, that depends on what your ram is rated for. I am not sure if 1.65V MCH is enough but maybe someone with a similar setup will show you how.
