ASRock 775Dual-VSTA overclocking experiences?

There should be.
I have not measured the difference.

Such a difficult choice...should I upgrade to a X2 4400+ or get the ASrock + E6300 for about the same price, now that it seems ok to carry my 6800GS PCIe and 2GB of OCZ PC3200 over.

You can only select the RAM speed in the BIOS. Divider is automatically set. Since I'm using only DDR400 currently, can only confirm these dividers

DDR266 - 3/4
DDR333 - 3/5
DDR400 - 1/2

EEL..or anyone else..i don't get this on the dividers..i have my fsb set to 290 on the cpu. the ram set at ddr 400..in cpu z, on mem tab, the ram speed is 3/4, not 1/2. explain, please.

 

[aussieburger]

mine is 3/4 as well (ram set at 400). I think it also depends on whether you have the flexible ram thing enabled as well. My ratio was different when I disabled that (unfortuantely can't remember what now)

 

[tenax]

ahhhh...interesting, aussie. i have not tried overclocking with it disabled. i used to understand the fsb and ram timings in the kt266 chipset days, but it goes beyond my brain these days..read an explanation about all this on another couple of forums, but it got so much into back and forth debates on it that i don't know who or what was right

i do note that for kicks, i left my fsb at 290 last night but changed mem to ddr 333 instead of 400 and when i rebooted the fsb and mem frequencies didn't change at all.

 

[aussieburger]

interesting ... I don't understand it now days either ... just tried it once and the ratio didn't look good so I changed it back ... I wish someone from Asrock would pop on here and explain all the bios settings in terms of what they actually do but anyway ... might try and see what 333 does for me as well

 

[tenax]

i know whether i had the fsb set at 280 or 295, that 3/4 ratio did not change..that's a fair difference so i thought that would be enough to impact a change on the divisor.

I don't get how to set the memory dividers or DDR RAM speed properly with an overclock on this board with an E6400.

It seems like the only options I have on memory is "auto, 166, 233, or 400" I tried with the "flexible" setting on and off and although it boots up at 295fsb, the RAM was set at 590.2 :shocked: with a 1/2 divider.

Then I tried setting it at 400(it's DDR400) and it seemed good with a 295fsb and a 3/4 divider said RAM was at 393 but produced errors in orthos.

I'm back on stock until someone can figure our how to overclock this board with PC3200 DDR RAM. It runs fast and stable with no overclocks but heck, where's the fun in that?

hmm .. .that's what I have and no errors in orthos yet at 300fsb ?? maybe try running dual prime95 without the front end (orthos) and see if you get the same result ... I remember reading somewhere someone with a conroe cpu who had probs with the beta orthos but not when just running dual p95

a question and an observation..when you had the 1:2 divisor showing, what were your settings at the time..just curious...(fsb and memory setting)

i've been overclocking to 290 entirely stable with no errors for 3 days now, so i don't think it's an issue of whether it will overclock..it's simply how much overclocking we can expect..given it's a 55 dollar board, i really think we are expecting too much. as i noted earlier, 2 years ago, a 260 dollar asus board wouldn't do better than 285 stable (and many boards were in the same boat) so, in perspective, i think we should be darn happy it has any overclocking capabilities! just a thought

the other thing i want to note is that not having increments for things is unfortunate and you would think that a bios that had increments instead of "high, normal, fast" type stuff would not be a hard thing to do. i don't know enough about bioses to know if it would add that much developmental expense to do so..you wouldn't think so..but i'm not a computer engineer

Just overclocked my Pentium D 805 on the Asrock 775dual-vsta motherboard from a 3360MHz stable with stock voltage to 3700MHz stable with a CPU pin volt MOD.

I did the 1.420Volt mod and the voltage in the CPUZ is gone from 1.216-1.232 to 1.36-1.376 and has allowed me to overclock my D 805 another 340MHz.

Memory has gone from a 5/6 divider to a 1/1 divider automatically with DDR2 2T.

She?s cranking and so are the temps from 40 idle to 47 idle now, ambient is 24.
Might try a higher voltage mod soon and get this to 4MHz on a cheap Asrock 775dual-vsta motherboard Wow happy happy.

Here is a pic of the 1:2 divisor Text

Obviously I had the FSB set at 295 but not sure what the RAM was set at other than auto or 400. Not sure if flexibility was on or off either but other than those 2 settings nothing else changed in memory settings.[/L]

Well, I guess I was just a little too agressive with my overclocking. I now have it at a "conservative" 290fsb and the ram is running at nice settings and speeds. And stable for at least ten minutes in Orthos. 46 top temp either so I guess I got lucky enough.

I might try babystepping it up a point or two in the fsb but for now I'm gonna test it the way I really use it... in a game of COD2 online.

thanks a bunch for info, beach..mr. vain, we should call you "mr. volt" seriously, i've never been a fan of volt mods myself..too much potential for messing up a cpu and board..that being said, if it only involved modding the board..for a 55 dollar board, i'd try it on this one! i assume it's a processor chip mod?

 

[abackwardsman]

This board kind of sucks for overclocking. The highest I can get stable is around 285 FSB although I do have ****** PC3200 Value RAM. That was with setting my RAM to DDR333 too by the way. Right now I just have the FSB set to like 278 so I can get a 100MHz overclock and retain DDR400 speed. I guess I was expecting a bit too much out of a $55 cheapo board. I'm satisfied though, Core 2 Duo ftw!

 

[tenax]

i think that's pretty amazing when you combo this board with value select ram to get that kind of overclock! it can't be a bad board frankly when it can take my corsair xms 4000 which sure, can do ddr 400, but lame timings like 3-3-3 and is able to run it automatically at cas 2 or 2.5...my msi could not , would not run cas 2 or 2.5, ever with this memory.

thanks mr. vain..like that much better than a wire mod. i might give it a try!

I would not try it on a Conroe CPU for now on this motherboard as it is the FSB that?s holding back the overclocks not the lack of CPU voltage so far.
If Asrock releases a Bios with an attainable stable 340 fsb or higher than 340FSB then a CPU voltage mod may be needed.
The D 805 has a stock multiplier of 20x with a 300FSB that some are getting with this motherboard could yield in theory= (300x20=6000Mhz Conroe killer.)
Of course you would need the perfect chip maybe dry ice or a Peltier cooler and the 1.6 CPU pin volt mod to maybe get there.

 

[Skeeedunt]

This thread is great. Thanks to everyone who's contributed. I might jump in on this with either a 6300 or 6400 in the next week or so.

I assume everyone's using the stock cooler?

I completely agree. A volt-modded Conroe would be pointless on this 775Dual-VSTA motherboard as the limitation is the board itself.

Not to mention volt-modding will void your Intel warranty.

I can't speak for everyone but I am using the stock cooler but I scraped off the factory thermal gunk and put on a super thin layer of ArcticSilver3 instead and it's been running nice and cool even with my modest overclock. :thumbsup:

 

[lepump]

The stock cooler was too loud for me.. got me a ninja on 900prm and i'm enjoying the silence

Have to say that I'm no longer missing Asus, this board is great (for 50?)

Keep it coming folks, good stuff

I?m still using the stock cooler on my D 805 (at 3700 MHz now) but its not cutting the mustard at these high overclocks. It is good to around 3400 MHz.
I have a liquid cooling kit that I will have to install in the near future.

From what I read the Conroe?s are running low temps with the max overclock that this board allows for now so stock cooler looks sufficient.
