ASRock 939Dual SATA2 wont POST!

[Jacksn]

HELP PLEASE!!

I made the jump yesterday to the ASRock 939Dual SATA2 w/ a Retail/box Opteron 148 CPU (CABYE stepping) from Monarch computers (there local for me). God forbid I should get it to power-up on the 1st time, right? Well... exactly!

I have a OCZ Powerstream 520 ps, 2- 512mb sticks of OCZ PC3500 DDR memory installed, Opteron 148 CPU, Segate SATA HD, Plextor DVD burner, and a eVGA 6800GT (AGP).
When I power up the system I get nothing but a blank screen. There are no error beeps or anything! The CPU and chassis fans spin, so the board and case are getting power, but no POST action or beep codes.

I have tried re-seating the memory, switched out video to a normal PCI Matrox card, disconnected HD & DVD drives. (note: I know for a fact that the 6800GT and the memory are in working order)
I still keep getting the same problem though, no matter what. Does anyone have any ideas whats going on??? Also, my power supply has the combo power connect for 24-pin, but the board only req. the 20-pin portion- so this is what is plugged in.
But I noticed a 4-pin connector off to the right of the 20-pin connector on the ASRock board that reads: "ATX12V1". What is that for, and do I need to have it connected.

Any and all info regarding solving this issue and how you may have your rig setup would be GREATLY appreciated. THANKS!

Did you plug the 4 pin 12volt line into the motherboard also? I had a similar issue with my eVGA NF4 SLI board because I forgot to plug that in. You only need either the 20pin OR the 24 pin plugged in.

IF you read your post in the Asrock mobo thread you will see that you HAVE to plug in the 4pin connector to the mobo. That goes straight to the CPU. Its the 12v line.

Figured it out. Thanks for the help!
Up & running with Win XP loaded. So far so good...

Still running great with this board and the Opteron 148.
I still had the voltage underclocked @ 1.35v lastnight when I took the chip to 2.5Ghz.
Memory running @ 178Mhz 7-2-2-2 1T
It never got above 42c with stock fan while "burning". I ran some loops of 3Dmark2001 and Super pi together for about a 1/2 hour and it never even broke a sweat. This chip and motherboard have some serious potential for the investment. Next mark to reach is 2700Mhz... will keep you posted.

Well... I'm dancin' that jig this afternoon!
I've got the Opteron 148 running @ 11 x 255= 2.82Ghz default volts (1.35) stable.

HTT=600Mhz
Memory=166Mhz divider (volts=high) memory @ 200.03 Mhz
The rest of the CPU settings = AUTO
Fast Writes= Disabled

It was begging me to go higher, so we skipped the 36 hour burn-in and went for it!
The system was stale so far thru, 4 loops of 3Dmark2001 @ 16x12x32x4XAA w/ SuperPi in the background calculating to 32M. We still have many hours of "Burn" to verify but, DAM!! this ASRock/Opteron upgrade has turned out to be the best PC purchase/Upgrade I've ever made... and I mean that. Cheers to ASRock with the finest budget board ever made that competes more then well enough with the premium products out there right now (Nforce4, etc.). I am one happy skunk right now. BTW- This is all with a stock cooler HSF on the CPU not ever getting above 42c.
Great stuff!

I was able to reach 11 x 273= 3003Mhz (3Ghz baby!) last night @ 1.45v (Stock cooler)
I'm pretty dam happy right now... I don't think I will do the vmod.
This is good enough! (fingers crossed behind back, thinking of conductive paint & a Zalman 9500LED HSF).

As soon as I went to 11 x 257 (2.85Ghz), I had to go from 1.35v to 1.375v for stability.
The next step was at 11 x 264 (2.90Ghz), I had to go to 1.425v for stability.
From any settings of 11 x 268-273, it req. 1.45v
Final goal reached was @ 11 x 273 (boards max.? with official 1.20 BIOS???) for 3GHZ @ 1.45v

I did not try to go any higher yet, because of the claim that the board may not go any higher on the FSB/HTT. I just want to burn-in at 3Ghz for now and maybe in the future get really bold.... but this is pretty dam awesome if you ask me!

3GHz? Nice! I assume you have one of the great weeks/steppings of the 148 then

Edit: Yes, I think the HTT is limited to about 274 on BIOS 1.2...try using OCWB1 which I believe does not have that limitation. However, with the speed you're already at...I don't think you really need any more HTT speed

The stepping on the Opteron 148 is a:

OSA148DAA5BN
CABYE 0540FPBW

Maybe one of the best batches of cpus in history! An FX-60+ chip at a $1000 cheaper!
