About those voltages though, I don't know what to make of them. Mine are normal, I don't want to suggest the vcore mod if yours are weird, I havn't enough knowledge of this board. Hopefully what? can help us out with this, he has the same board and he knows a lot about it. I just hope he can help me with that weird cpuz thing I'm getting.

Another note on my problem, I can put my FSB at 225 when I put the multiplier at 10x. cpuz reads 225 x11 = 2475 because it is doing that weird 11x thing, but My Computer says 2.25GHz (225 x10). My computer will boot on this, but it can not boot if i set my BIOS to 225 x11 = 2475MHz. So, in both cases cpuz would read 11x 225 = 2475 but wont boot in one case. This leads me to believe that cpuz is having an error reading my speeds. But then I go to BIOS and set my FSB to 240 x10. If cpuz is really just misreading and the speed in My Computer is correct then it should boot fine (It can boot fine at 220 x11 = 2420Mhz) at 2400MHz, but it doesn't. This leads me to believe that cpuz is correct (and it's not booting because 11x 240 = 2640 = too much for stock air) and My Computer is wrong. Ahh, contradictions! what?, if you can help solve this then you will get all my rep points forever!
How safe do you feel about flashing your bios? They are quite easy to do if you have a floppy drive, even if you don't I can tell you how. I have the dual sata II and have successfully been able to overclock with out any issues at all. Seems to me like you bios need to be reflashed.

redownload the 1.2 and reflash the bios. I will try to help as much as I can since i have hands on experience with the board. At work right now, but when I get home. I'll message you.

I'm comfortable with a lot of risky things. I've flashed the BIOS from 1.0 to 1.4 then down to 1.2. I have it at 1.2 right now. (I think, is there a way to make sure?)

Ok, I have BIOS 1.2 installed. Do you suggest I get the OCWB BIOS #1? And can I install that using the same tool ASRock provided for BIOS flashes? Also, should I disable things like Cool n' Quiet and boot guard when overclocking? Will they make it more difficult or just safer?

Yes pls disable cool and quiet !
edit: You should be fine with 1.2 official since you arent going anywhere near 270fsb.

leave boot guard on, that ones ok

Dont even bother lowering your multi anymore.
What i meant for you to do was to just leave it at 11 and work with it. The high multi will work to your advatage since you are using 1gb ram modules. Which wont overclock much. Apparently in the reviews on newegg it says most people run their modules at 2.5cas .

So maybe try cas2.5 - 3- 3- 10tras . Work at a 1:1 ratio until its not stable/ cant boot , then apply the divider. SO try, something easy 210x11 1:1 (ram at 200) . Then slowly apply 2-5mhz and reboot until you cant reboot. Then set the ram at a divider, and keep going until you are satisfied.

Embrace the 11x multiplier ! This has been a PIA for you, but it will be worth it when its all over.

Guys, trying to do the vCore mod with a trace pen - I have the contacts nicely bridged, but the damn thing won't go! It's like it's still not being bridged or something...is there a resin over the contacts that I have to remove? With OCWB1, I'm at 280HTT with a 5:6 ram divider (which puts me at 280x9, or ~2.52GHz). I'm already astonished by what I've got out of this board, but I know it can do so much more. I've got a friend here with a soldering iron with a nice, fine tip, and some real thin solder too if I need to...

Solder vid4 to grnd. I used conductive paint. Not sure if the pen works. Soldering will work for sure. Just put the bios vcore at 1.125? uh lol i forgot what it is exactly to be at 1.55...<--the long term effects of drinking too much

There are a few methods to do the mod. Here is the chart with the required settings in bios and actual output. Courtesy of Ed of OCW.





Taishan- you may not be getting a good connection. get a fine needle and CAREFULLY scrape top of the VID and SGND, there MAYBE resin over it, If not, I think its an easy job with a solder Iron. (use masking tape and cover the rest of the contacts).

Muftobration- do as what? suggests. He's right on the money so far. Don't mess with the multi quite yet. loosen timing to 2.5-3-3-10
But i suggest you find the max cpu OC at this point, so it would be a good Idea to set the mem speed to 166 for now until you can find the max your CPU will go.

I will try to take a pic of my bios and post back.

I'm doing variant 1 (VID 4 & SGND) since they're so heinously low, I wouldn't use them anyway...and it's far away from something that the bios might try to default to (and incidentally could ruin a chip if it's too high). I might try to solder it tonight...I'll let you know. I've pulled my multi to 8 and bumped HTT to 300 (so my ram is at 250 right now). That way I still have 2.4GHz with my ram at almost it's max (I should be able to go all the way to 260 (maybe more) on the ram without incident, as far as I've tested). The funny thing about this A64 is that I keep forgetting that the proc can now cause memory errors if it's pissed (since the controller is on-die), so I have to be careful that I'm not blaming my ram for my proc being pissy...
