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

I do use async when overclocking. I touched nothing else, only the FSB for the CPU. PC seems stable at stock, im currently using it with a FSB of 250MHz.

I should easily be able to at least boot at 275, i cant boot past around 265!

As to temps, TAT is reporting 34 at the moment on idle.

Will run orthos now to see if 250 fails after minutes and will post new temps
 
Yeah it seems whacky. You should be seeing 3GHz on stock volts at least. Your temp isn't wonderful but it isn't poor.

Will read up on the E4500 (M0) stepping some more, as the 11x is increasingly attractive.

However with my E4300 I am in the same boat, I cannot get past 266 with a PCI-E card, but could get 300 with a AGP card and sync on the PCI-E. Are you on PCI-E GFX?

Got a 7600GT AGP so thats not the problem :(

Just been gaming for 2 hours and the PC has been fine, thast a 250 FSB and any higher seems to be instable

Using the same board and mine falls orthos at 275 and doesn't boot at 300.
Have the E4400 using a AGP card.
 
I experimented and researched, Anandtech forums seem to suspect that the PCI-E is never async, even after setting the BIOS. So if anything in your system is sensitive, you will lose hard.
 
I'm just about to order Crucial Ballistix 2GB Kit (2x1GB) DDR2 667MHz/PC2-5300 CL3 2.1 V unbuffered non-ECC.

I'm currently running an E4400 & X1950 Pro in this board. With a view to upgrading the board sometime in the future, is there faster RAM that perhaps runs in the board that i should be looking at?

I'm only buying the DDRII now as I'm giving my DDR to my son & it's cheaper to buy new DDRII than 2nd hand DDR!!

Cheers.

Not to worried as i'm using his board as a stop gap. As soon as i move off AGP i will be swapping it.
For the price and what it does i cann't realy complain, as its a great stepping stone on the upgrade path.
 
HELP - The picture says it all:

Well you'll need to be very very lucky indeed to get beyond 300fsb with a 4core/vsta. These posts from people claiming to be getting 320 plus I take with a large pinch of salt.
Peg it back to something more sensible and enjoy the stability. 2.6ghz with an e2160 is a nice clock and will run everyday programs and games very well. Thats the true test, not squeezing a few more points out of 3dmark.
 
My line of thought was this - The boards overclocking ability is limited due to the PCI lock failing. So if I can boot into windows, i.e. HDDs working, then surely my PCI bus is not overclocked (locked @ 33.33Mhz)? If I set the FSB to 304, then as soon as the BIOS activates my HDDs the system hangs (lock failure I'm thinking) so 302 meant PCI lock in working order.

In short: If I can boot into windows my PCI bus is @ 33.33Mhz

Is this an incorrect assumption?
 
anyone using this board on vista with a nvidia card ?


from browsing the wed itseems the nvidia drivers and mobos chipset dont get along :/ gfx corruption in windows :( havent found a solution either
 
Got my OC stable @ 290fsb - 2.61Ghz which aint bad I suppose. RAM is on the 8:5 ratio so underclocked to 184Mhz with default timings (which timings are the most beneficial to tighten?)

Now, my gfx card is letting me down, heh, there's never a happy medium is there?
