ASRock 775Dual-VSTA for Conroe (Core2) with both AGP/PCI-E and DDR1/DDR2 support

You have to scroll down one of the BIOS menus - its not apparent from the first page.

I cant remember which screen its on but its definitely there!
 
Hmm, if it works (sometimes) for 9550 and not at all for the X600.

If the X600 has a higher power requirement, then I must suspect the PSU. Try another if you can. Or reduce the number of components with the 9550, remove optical drives, extra cases fans, and see if it will crash.

Would still like to see TAT and ATItool temps though.
 
right , im still running this board with a core2duo and am still pretty happy with it and its performance

if i was too upgrade my gfx card ( from an AGP 6800gs ) would the board bottleneck it or anything else bad

i know it only supports certain pci-e cards , is there a list of ones compatible anywhere ? what are people here running ?

cheers

Well the PCIe slot runs at 8x rather than 16x speed. From what I've read though I don't think you lose that much from this deficiency.

I'm running an ATI 1950XT pcie card, and have no problems whatsoever with it.
 
Found out today that this board doesnt support 4gb of RAM which was very annoying for my mate as he bought a 4gb kit 2 x 2 gb.

Im just wondering why it doesnt say this on OcUK site. Think its quite important to be honest.
 
Use onboard sound or Audigy 1 ?

I now have the 4Core board. Would anyone say the onboard 8.1 sound is better than an Audigy 1 Platinum soundcard in terms of sound quality and CPU overheads?

Thanks.
 
I now own this board. Does anyone have any objections to starting a seperate thred called something like 'Official ASrock 4Core Thread' just to keep things tidy?

This is a great board IMO. Only prob I've got is having a 3-pin power LED connector and the board takes a 2-pin (easily resolved, I know :P)

I do have a couple of intial questions however, these are:

1) Does this board have the FSB wall that the older 'Dual-VSTA' had, i.e. anything more than ~33Mhz and the OC fails? Initially the board automatically booted into a FSB of 266Mhz with no hitch but I quickly reverted to stock when I realised it wasn't right.

2) How do I view my DRAM voltages?

Cheers
 
266 is the correct fsb for the e6xxx range of c2d's, the e2xxx and e4xxx are supposed to run at 200fsb but will run no problem at 266 on this board using the stock cooler.
Voltages are as previously posted in this thread
DDR "high" 2.73v
DDR "norm"2.63v
DDR "low 2.53v

DDR2 "high" 2.0v
DDR2 "norm" 1.9v
DDR2 "low" 1.8v
 
Good, so there would be no point in buying a e6x00 CPU for use with this board, unless you NEED 4Mb cache? So theoretically I can hit 2.7 (+33Mhz to 266)
Sorry about DRAM voltages should have searched.
What about a dedicated thread to this board?
 
I posted some bios shots here

I have the same system as you or at least one of them is, e2160 4coredual/vsta. The clock is 2.6ghz as I'm using DDR2.
As for reaching 2.7ghz it'll depend on your other hardware.
DDR400 is good and clocks better than the DDR2 667 I have now. But the best clock will be achieved with AGP gfx and IDE drives as this keeps the pci-e limitations out of the equation.
With DDR400 IDE and AGP I was stable at 2.7hz (300fsbx9) but to achieve that meant setting pci-e bus to 117mhz, definately a no-no if you have a pci-e video card and would corrupt your data if you had sata hard drives.
Last word of advice leave memory settings at auto meaning your DDR400 will be recognized as 166mhz instead of it's rated 200mhz. This is necessary as there's no way to set a divider so as the cpu's fsb is raised so the memory will increase too. IIRC my ddr400 was around 187mhz when the cpu ran at 2.7ghz.
 
No you misunderstand, both pci and pci-e can be locked it's just that this particular via chipset will give a bit more stable cpu o/c if you up the pci-e fsb.
 
Thanks Ron, will I be OK using stock cooler and stock volts?

Edit - I am using legacy devices (AGP, IDE, DDR1) so should be worth a try if you recommend giving it a try on stock?

Stock cooler fitted correctly will be fine for the speed you're likely to reach on the Asrock. At 2612mhz mine never went above 62 degrees C during 13hrs Orthos blend.
 
Thanks Ron, my idle temps at stock clocks and volts are (according to speedfan) Core0 -23C and Core1 - 20C are these about right?
