most of the problems could be considered "general instability". For example, I just rebooted it and almost immediately I got a fatal exception in explorer.exe. Dr Watson hung, but when I went into the task manager to end the drwtsn32 processes, everything seems to be fine now. Prime95 runs fine.
Earlier, it just hard froze. It's definitely not stable, despite the ability to run prime95 and 3dmark.
Yes ...I failed to mention that. There is a vdimm mod that a very few have done. I'll see if I can link to it.
You mean vcore?
My mobo (without mods) can only allow a vcore .05V higher than whatever the stock vcore happens to be. Is this the case with the A8R-MVP as well?
The fix for my board was simple. There's a voltage regulator chip which reads the stock vcore through a 5-bit binary code. Since there is a "break out" set of contacts on the board which are easily modifiable (ala the T-Bird/Duron unlocking days) you can unlock the maximum possible vcore with a dab of rear-window defroster repair paint.
I couldn't get my HTT as high as I did without bringing my core to as high as 1.525V (the max allowed with the mod is 1.55). I'm surprised these higher cost boards can't go any higher w/o modification.

You got it man!

higher cost? LOL ...this is a $99 board.
Apparantly all of the asustek and assrock boards are going to this for some reason. It's not making many ppl happy.
i'm not rubbing it in yet... AquaMark3 just crashed with an exception, although the system is still running. In fact, I'm writing this post from my system just seconds after the crash.... I'm going to try 3dmark again.
BTW Prime, set things back to the stock HTT and see if that "general instability" goes away. I'd say you're running unstable if you're getting crashes like that, even if they're not crashing the kernel.
Maybe I spoke too soon. I rebooted, making no changes, and now it seems much better. I was able to open CPU-Z, take a couple screenshots, open photoshop, crop and save, open CuteFTP, upload pic, and post this at this moment at 295x9
i got a spontaneous bluescreen, but it indicated my wireless NIC driver (Netgear Wg311T pci). Perhaps my PCI card is limiting me (or the driver) instead of a bus/cpu problem
believe it or not ...I could never get my mem frequency stable beyond 237/238 until I uninstalled the soundmax drivers. Afterwards I let windows install it's own hd drivers and now I'm able to take it to 242 stable ...which is about where you'd be at 295/296 so I that is my suggestion.
idunno anything about the pci latency timing to be honest.
if that seems better but not quite stable enough you could back down some more off the peg ...maybe even disable it til you get a happy stable htt.
You shouldn't have any reason to touch your PCI latency speed at all if you're running your PCIE/PCI bus async from your primary HTT. Your PCI speed is always 33 Mhz (and your PCIe @ 100) no matter what speed HTT is.s
have you ever tried the stess prime sp2004 test? It makes things so much nicer and easier with the gui ...all you do is run 2 instances like you do cpu which can run off of a single installation. You check off which core you want to test and select the appropriate affinity setting. The best part is you can even test each core indepently.

It's such a handy tool. I always let it go at least 35 mins now because I've have most failures at around 33 mins. Sometimes a restart will cure it though. The board gets hiccups sometimes.

I'm currently at 285x9
edit:\ i did post at 2750 earlier but it bsod'ed as soon as I got to windows.
As you go up in htt ...when you enter XP generally and you get that instability feeling try a restart. Sometimes that helps.

EDIT: Here's what you guys need. Its not quite as easy but it gets the job done.

Yeah that's the link I was looking for.
care to illistrate?
htt to 290
command rate to 1t
keep moving forward!
basterd!
Wes even updated his review as sort of an apology saying everything he achieved after 260-265 was at 2t because of an inadvertant reset.
Which drivers do you have loaded (besides the video)? I'd like to duplicate what you have when I do my format.
That's it. Neat huh? :P

Doesn't look much like the mvp board layout does it?
dual slot config to single instead of auto
rd480 ht pll control to normal
htt to 295
pci-e voltage to +1.30v
PEG Link Mode to normal
PEG Buffer Length to Longer
wish me luck
Windows barely booted. Then NT AUTHORITY initiated a shutdown
backing down to 293
About to run a graphics test...
i got a spontaneous bluescreen, but it indicated my wireless NIC driver (Netgear Wg311T pci). Perhaps my PCI card is limiting me (or the driver) instead of a bus/cpu problem
Any hints on the PCI Latency settings? I'm using one PCI card - my wireless NIC. It's currently set at 64. Should I change this?

more to follow.

Thanks Omega!
Whee! What's next?
