ASRock 775Dual-VSTA

[homonculus]

bluescreen1337 (sic), why the hell are you using this motherboard when you 'obviously' have more spare income than donald trump (8800GTX indeed!).

Thread hijackers aside, I've just discovered an easy way to find your highest stable FSB on this board (with PC3200), simply down spec your RAM to 3-4-4-8 and set to DDR333, then just keep pushing the FSB until the chipset falls over. 317 in my case, now you can reset to DDR400 and away it goes.

The Bios settings are simple, since my graffix are AGP I ignore PCIe and leave it synchronous, disable everything else on the CPU screen except boot guard.

On advanced chipset features set the memory timings manually, flexibility disabled, dual channel, 1T command, DDR voltage to high (AGP voltage normal since my 7800GS falls over on high), drive strength highest, DRQCTL pipeline enabled, everything else on default or auto.

Superpi 1M = 23.891 secs.

Aquamark 3 = 101,898

Happy results, gonna keep fiddling maybe look at the 12v line since the board reports 11.31v (definitely NOT the PSU), try 2T command and maybe tighten up the timings a little, and mod the 7800GS cooling system since it's definitely the heat holding my O/C back (crappy stock cooler doesn't sit on the memory chips) .

I did change the NB heatsink for a better Zalman NB47, and used the stock sink on the SB (waste not, want not), I think this helps.

Idle temps 35, 36C on the bundled cooler, peak at 46C! Who needs expensive heatsinks with C2D

BTW you guys were right, Quietfan does not work on bios 2.20 it's just a coincidence that the temps were at the level I set in the bios. Sorry.

Bring on the modded bios's, worked a treat on my old NF7! (thanx merlin)

Been using this motherboard and ram to slowly start upgrading until I find a 680i motherboard I like. Mainly just waiting for a extensive review of the ASUS Striker Extreme and new boards to be released. I choose this mobo a while back because I had an AGP 6800GT and didn't want to fork out the extra money for a new card when I knew the next gen nvidia card and mobo were just around the corner, but I did want to upgrade to Core 2 Duo at the time so there you have it.

Oh, and the vista drivers I found didn't have support for the 8800gtx yet so still haven't been able to try vista out.

 

[flevio]

The system will boot initially but after any drivers are installed for the 8800gtx it will get just past the windows loading screen and stay black for about 5 minutes or so before displaying a blue screen about nv4_disp display driver stopped responding.

Tried the EVGA and ASUS 8800gtx with win2k3, winxp sp2 and winxp 64-bit. Same type of error on all of them except winxp 64 bit, the screen will stay black for about 20 minutes before the system just restarts and repeats. I'll give vista a shot this week since I found some drivers that might work

Bios 2.20:
Primary Graphics Adapter set to PCI Express Gfx.
AGP settings set to default factory settings
DRAM Frequency set to 333MHz (DDRII667)

System works great with my old agp 6800gt but not quite there with the 8800gtx yet.

CPU=E6600
RAM= pqi TURBO 2GB DDR2 667
PSU=Thermaltake Toughpower 750W
HDs=2xRaptor WD1500ADFD in raid 0.

if you havent next time trie a clean instal with an pcie card(8800) from the start..
turning prom agp 2 pcie after might be a problem.

Why didnt you trie setting pcie voltage high? (it has that option for agp.. does it have it for pcie? i cant c right now..)also the first time you do that put memory in flexible mode.
play with other bios graphic settings also..
since the pc its booting and the screen is turned on then its a driver prob.. you should also wish nvidia put out a pcie4x compactive driver(pale...)
homonculus- why the hell did you buy an fsb 800 chipset if you wanted 2 overclock a 1033 cpu?...
its not about been tramb .. a dx10 card its the final upgrade in mind when someone has this mobo.
making cheap staff ,work good its a chalenge that euryone likes..
but since bLuEScReeN1337 alredy has ddr2 you are a bit correct..

For me that link seems to show that 775Dual-VSTA does not support the quad core.

I remember that the CPU support list included the qx6700 for 775dual-vsta (from BIOS 2.10). They changed that as they changed the description for BIOS 2.20 too. Bad Asrock, bad! !

Yes, they obviously changed the page. Bad ASRock indeed! :laugh:

I'm not especially worried as I will be on a new motherboard, probably a 680i SLI based board, well before I consider a Quad Core.

 

[sMiLeYz]

does this mobo support an xeon 3040?

It's true that page did previously show that 775Dual VSTA supported the QX6700(B3) with bios 2.20, and now it?s gone!

IMO it does not matter too much that they have taken it out of the list, as lot of people have the 2.20 bios and should be able to use Kentsfield CPU?s with this mobo as was originally shown in the list.

The removal of the Kentsfield from the 775Dual-VSTA support list could be part of a future strategy to promote the Asrock 4QuadDual-VSTA as the choice board to get for Kentsfield CPU?s.

Hi, I have built myself a nice stable system
asrock 775 dual-vsta
core2 duo 6300
Radeon 9600 agp
I gb -512MB DDR2 PC2-4200x2

But I thought a better graphics card would be a good idea,so I got a
Sapphire Radeon x850xt 256 Pcie.
Now it won't even boot with it installed.
I get a blank monitor,no post beep and the HD light stays on,and can't access the bios.
all the fans are spinning and I have connected the power lead to both the videocard and the 12v for the
cpu.
When I remove it and put the agp card in,all's fine and it boots into XP no problem.
Has any body had a problem like this and would like to offer some advice?
Thanks in advance .

 

[homonculus]

Have you tried setting the default display adaptor to PCIe rather than AGP in the bios BEFORE you change the cards over? Otherwise I suspect your power supply may be junk, you don't mention it which suggests you probably don't have enough juice to run the card! (see my sig for PSU reality check)

[soybeast]

Just wanted to let ya'll know that this board WILL run a core 2 duo with pc2100 ddr266 ram. It's been pretty nice so far I guess...although a lot of programs have been crashing for some strange reason. Dunno if it's an instable motherboard or bad ram, or virus/spy-ware that's causing it......

 

[homonculus]

Which errors are you getting? 0x0000007f, 0x0000008e, IRQ less than or equal? If so these are all related to the memory being pushed too hard.

Bios 2.10/2.20 gave me alot from using bios 1.90 when running DDRII, from 280fsb to 325fsb

What settings did you use to get it to 125 FSB?

Hmm nothing special, the new bios(2.10-2.20) did most of the job.

ddr2 @ 1:1
volt's @ high
timings @ auto

pci-e/pci @ 100/33mhz

Think i just leaved anything else at default.

 

[soybeast]

Just random programs crashing. Winamp seems to like to crash quite a lot...

 

[homonculus]

Haha, winamp IS spyware!

Use something safer. Did you do a fresh OS install after changing the mobo?

 

[zaqzax]

hello again
i bought today a-data 2x512 ddr667 ram.

i can o/c to 292Mhz fsb (10:8 ratio) = 365Mhz ram (730Mhz effective)
when i try to enable flexibility option it gives me 0,75 ratio then i can
o/c to 300Mhz fsb but 225Mhz for ram (450 effective) to less for me
i set fsb to 333mhz and choose option flexibility to get 250mhz (500mhz effective)
ehh, not starting.

What i can do ? try to set higher voltage for ram ?
what is low, normal and high -- in voltage for ram ?
setting 533 and 667 or Auto for ram nothing do for me.

292fsb and 730 ram ...
or
300fsb and 450 ram ...

fmmm :-D
i will try higest fsb setting with 10:8 ratio, but i know when i set it to ~295
pc will not start.

 

[vandeste]

Even I am having DRAM:FSB issues when using this mobo with Core2duo and using ddr.
I can not get the ratio out of 8:4 ratio...


My system:
E6300
2 512MB Kingston Value Ram pc3200 (ddr 400)
ASRock 755-Dual VSTA

** set fsb to 300 just to get better performance - had not gone any higher
-- should I???

 

[zaqzax]

on fsb 292 and other same settings that i wroted in previous post
-- system halted when i watch tv (tuner) and testing in prime,
i set now to 288fsb.

i setted v-link and ide setting to higest -- this could be problem


(sorry for my english)

 

[zaqzax]

****** i have still errors, i set to 288fsb and ratio 10:8 = 360Mhz for ram.
too high :-/

i dont know what is wrong, vlink and ide settings (set to highest) or ram freq.

 

[homonculus]

vandeste: did you actually read this?

"Down spec your RAM to 3-4-4-8 and set to DDR333, then just keep pushing the FSB until the chipset falls over. 317 in my case, now you can reset to DDR400 and away it goes.

If so what was your result?

zaqzax: You have DDR2, but the best performance will still come from flexibilty disabled, DDR730 on DDR667 ain't so bad! Leave IDE strength at highest, v-link unlikely to be the problem.

 

[zaqzax]

ok, i have stablility now
285mhz fsb = 357mhz ram (713mhz), vlink and ide strength set to highest, dram voltage set now to auto (setting to highest nothing do for me).
i dont want to set higher fsb in cost of ram freq (0,75 ratio -- on 300fsb = 225mhz (450mhz) too less).

my friend have on my memory 405mhz (810mhz!) ---> asus p2b ---> nothing to say, quiet

 

[JeremiahTheGreat]

Anyone have ideas how how much the 4x PCI express port will limit future upgrades? For example, would a Geforce 8800 but absolutely limited with this board?

 

[vangeezer]

Hi, does anyone have or know someone who has installed and is useing an Ati x850xt
pcie card on this board.If so how is it?
Thanks

agp "high" 1.59v
agp "low" 1.54v

DDR "high" 2.73v
DDR "norm"2.63v
DDR "low 2.53v

JKKOSKI found the actual DDR2 voltages as per the bios settings

DDR2 "high" 2.0v
DDR2 "norm" 1.9v
DDR2 "low" 1.8v
