**The ASrock 939dual-SATA2 (ULi M1695) thread**

Really liked the idea of this board with AGP & PCI-e and it ran great with a 6800GT on x64 but had slight problem in that i manage to kill 2 of them without even trying ... just disabled the primary IDE channel and board wouldnt boot and bios reset killed second one completely first just wouldnt run OS or install it :mad: not that im advising anyone against it i just made personal choice to go nforce4 instead now with 6800GT in box gathering dust
 
I am very happy with this board, as its my 1st main pc build ever, managed to oc my 146 opteron to 2.7 with some help from ocuk members, Runs like a dream. I dont know if there is anything i can improve though as i dont know a great deal about oc. Like my memory in my sig, should i leave it as is, or do something with it, i know you can do something with the timing, but what does that gain ? and how do i do it ?

Also, eventually i shall buy a proper sound card instead of using the on board, how do i unistall the motherboard sound though ? get rid of it when i get a proper pci x-fi card ?

You can disable it in the BIOS under the "Chipset" menu :)

If you run a PCIe card on this mobo.....then reset bios so gfx defaults back to PCI, will you still get a picture during bootup with the PCIe card?

Ie. so you can get back into bios to change it to PCIe?

Thanks. :)
 
Yes, that setting just dictates whre the bios looks to find a gfx card FIRST, after it finds a card it will start up as usual. So if you have an AGP card and set it to PCI, the default, it first looks for a PCI card, then maybe an AGP, then the PCI-E.

BTW, if you have a dual core Opteron, as I do (a 165), try the newest bios (1.5). Mine used to be version 1.2, it identified the chip OK, but cool'n'quiet didn't seem to work and there was no option to select 1T command rate. I have now loaded 1.5 and Cool'n'quiet works (as identified by CPUZ) and the 1T rate has appeared.

I gave up on the OCW beta1 bios as the cold boot problem was almost permanent. Not tried overclocks on 1.5 yet.

Thanks for clarification there. :)

I am running a 146 on beta2. Absolutely no cold boot issues at all....in fact this mobo has proven solid as a rock (LOL) so far. Touch wood. ;) 1T works fine too on my PC4400 Corsair. Clocked at 2.95 so far.

Cool n quite, sure I read its best to disable that? Not even sure what it is but I assume it reduces cpu speed or fan speed during idle?

With the freezer 64 on it is already so quite I wouldn't be bothered about any other noise reduction.
 
Cool'n'Quiet drops the multiplier when the cpu is idle. On my Opty 165 the multi drops to 5 from the normal 9. The CPU volts seems to drop also, so saving generating extra heat. Opinion seems to be mixed over whether to disable it or not. On the nForce 3 boards it seems that you had to disable it to overclock successfully, and that appears to have stuck in the minds of the community, but more recent chipsets seem to be better behaved.

Glad to hear someone has got a board and bios combo without the cold boot issues!

A few trials tonight and it's clear the 1.5 bios still has the 273 MHz HTT cap. My cpu will boot at 285 using the Beta 1 bios, but not with this one. I'm still happy with my 165 though, it cost me not much more than a 3700+ and runs happily at 273x9 to give better than X2 4800+ speeds, very sweet! Would be nice to get close to FX60 speeds though!

I'm using an Evo33 cooler. With 2 instance of Prime running it levels of at 53 to 55 degrees, a bit on the warm side. I'll have to try that Artic Freezer Pro.

Sweet chip you have there. :D

Yep, I first flashed to 1.5 but was soon held back by the HTT lock. :(

ocw 1.2 has been super stable for me so far and with some further fettling I hope to hit the magic 3 gig with some luck.

At 2.95 I get max load temp of 50* so far. (1.5v) Would like lower but that is well within tolerance I think.

May try cool n quite for sheer power saving. Noise isn't an issue though luckily.

Seems that people think the big typhoon hsf is the danglies at the moment though. Better than the arctic.

It's HUGE though and isn't a simple clip on affair like the arctic which is great if your forever messing around with the PC like me. :)

If I swap from an AGP card (x800) to a PCIe card (7800gt) do I have to uninstall the mobo's AGP driver?

Anyone know?

And do I set the video output to PCI in the bios (does it actually mean PCIe??)

Thanks for your help. :)

no you can run dual cards agp+pcie.
 
I bought a pcie card to replace my agp and it didn't boot at all (reset bios etc).

So I put back the agp with the pcie as well and try to boot up. It didn't boot at first but them I put agp in bios and pc boot to windows but pcie still not picture (black screen). Finally playing with dual view (got 2 monitors) finally I got a picture on the pcie card as second display so thank god I did not return it as faulty (though about it).
So I end up removing AGP card with the all its drivers (including agp drivers), and booting finally the pcie without problems.

I read is even possible to run 6 displays on this mobo with 3 GFX.

I am tempted to get a third monitor but I am worry about what my girlfriend and my friends are going to think about my computer adition ;) I guess I still waiting for software to split a game between 3 displays....anyone know how to do it?

I've done a search of this thread using different key word/phrases but couldn't find an answer to this.

It doesn't matter what BIOS I use, but if I set the Vcore value from within the BIOS to 1.45v, it will stay at 1.45v until I shut-down my machine. When I next attempt to boot up my system, it wont boot into the POST screen but I have to turn my system off twice and then on the third attempt I get an error screen saying I can either F2 to change my settings or F1 for it to load the defaults.

If I go into my BIOS my CPU voltage settings have changed from a manual setting of 1.45v to the AUTO setting.

I've tried different flash files and ways of flashing my BIOS, but no matter which BIOS I use, official or OCW beta's, my manual setting wont save.

Can anyone help with this please as it's doing my 'ead in!!! :mad:

Get rid of her quick, they breed quickly you know! ;) . Before you know it you won't have time, space or funds to satisfy your addiction and you will spend all your time repairing the damage the kids do to the pc's you built for them! :(
 
Hi,

I need help with flashing the BIOS on this board. I will be flashing to the ocwbeta2 version. To flash do i type:

A:\FLASH ocwbeta2

or A:\FLASH ocwbeta2.rom

Please help, never flashed a board before and worried about causing some damage.

Cheers

Also is it possible to back up my current BIOS before hand or should I just download my version from asrocks site, just in case I have any problems?

A mate of mine has just bought one of these motherboards and I was having A little play with it this weekend. I was surprised to see that the cpu voltage only goes up to 1.45v. Is this right?

Yes, you need to do a very simple solder/ conductive paint mod to get it to do 1.55

There is also another mod with a resistor (that no one in this thread has tried to my knowledge) that allows 1.6+

Yes this is correct, although it is possible to do a volt mod to increase the vcore voltage. See this website, it was mentioned earlier in the thread (top of page 40)

I have added a resistor but I can't get above 1.55v with it.
I was under the impression that my resistor would add 0.2v to every set voltage in the bios but that doesn't seem to be happening.
