Asrock 775DUAL-VSTA overclocking experience?

[jmke]

I bought a very cheapo motherboard for my new S775 HSF test setupn this Asrock 775DUAL-VSTA board was/is only €54 at http://www.alternate.de/html/product/details.html?artno=GPER11&showTechData=true

Now I've had some success in getting the accompanying P4 3.06Ghz to overclock over default settings, up to 3682Mhz to be exact, at stock voltage

http://hwbot.org/show.img?style=2&imageId=1594

the asrock mobo doesn't allow for voltage cpu control, ddr voltage can be set to normal/high without any values defined in the bios; that's about all the tweaking you get, voltage wise. The FSB can be set beyond realistic values, but it seems the VIA PT880 Pro might be the OC limiting culprit, can this be?

When I push the FSB speed over 160mhz the system will stall, slow down, and blue screen, quite weird. It happened quite random, and then it started happening at below 160Mhz FSB also... I removed the stock aluminum NB heatsink and replaced the standard goo with Arctic Goop, and so far that has proven successful for several days of stress testing now. Could the VIA PT880 Pro chipset be this sensitive to temperatures & cooling?

How is the board besides overclocking? I'm looking at one for my sister. Her MB died and everything is really hard to get a hold of (RIMMS, etc). Its looking like a cheapo MB with a 6300 would be just as cheap as fixing it.

I'd go for 945G if I were you.

Conroe works on 945G?

Conroe works on 945G?
Some of them, yes. Examples:
ASUS P5LD2-VM SE (nice board, close to zero OC with onboard video on)
Gigabyte GA-945GM S2 (no OC at all, no options in BIOS)

I had this board paired up with a P4 530J 3.0 ghz stock 200 FSB.

I was able to get it to 3.6 Ghz with 240 FSB, i set ram voltage to high.

it's very cheap, accepts PCIe and AGP vga cards, DDR1 and DDR2 memory; the ideal motherboard to upgrade from an older system, and still keeping room for future upgrades without losing compatibility.

Very good board for new and old.. :toast:

Hello everyone, I'm from Latvia, so please sorry me for my English :rolleyes: Hope to stay here for long :)

I have the same MoBo, and a P4 524 (533, 1MB L2, default 133*23=3066 MHz) - the same as thread's author have.
Maximum OC that passes the POST(but win cannot load, of course) is 4100. OS can start barely on 170 fsb(first time started even on 171).
The maximal OC that is stable in Windows for me is about 167-168 on fsb, used to be sitting on 162 (3720 MHz), but noticed that it's not actually totally stable - hl.exe(Half-Life 1 \ CS 1.6) hangs up and crashes time by time randomly on that OC. So to be sure that everything is 100% stable i'm sitting on 3611 now. Although, on 162 fsb(or even higher, on 166) system is stone stable in all tests.

I'm taking part in a overclockers.ru forum thread about this MoBO, and i'd collected some information about it here - http://forums.overclockers.ru/viewtopic.php?t=152180&start=0 (but you probably won't understand much, since that forum is in russian :) ) The info i'd been getting last few month tells that Core2 overclocking usually reaches 300-310 fsb, if you get higher - means you are pretty lucky :) Also have some information about bios settings, stability etc. so if you need translation from that material or simply have a question - contact me, i'll help you if i can :)

And in conclusion, this MoBO is great for "slow" upgrade - you can go from your old AGP GFx\ddr400 to ddr2\pci-e video, spending minimal amount of money and your nerves :) And, so cheap mb that can not only run but OC Core2 - is very good, at least :)

I have problems in 3D with CPU ocing... When I set fsb to 280 - in all 3D I see that textures disappeared. (E6400, Sapphire x1950xt, Geil 8500 Ultra Plus, FSP Epsilon 700w). With agp cards i dont have such problem... I played with BIOS setting but didn`t find the solution. So what I should try? Maybe some vmod PCIe?

[moonsond]

Drager2 If you hasn't, try checking "PCIE Downstream Pipeline"... Disable it, i had awful polygon geometry corruptions with this option on...

BTW, maximum I'd ever got of my cpu on this mobo and could make screenshot, attachment
Win cannot load on such a frequency, I'd used resuming from hibernation(quitting all posible tasks, including explorer.exe before hibernation) for to take those pics...
..probably going to VID pin VM Vcore...

[tam2]

try this one for non-OC board, matx, e-sata and m-atx

moonsond Oh.. It doesn`t work... Bebches, games just freeze after that
...sounds that I heard it somewhere :)
