There seems to be a hotfix for the 0x00000124 BSOD's which will be in SP2. It's some issue between multiple PCI(-e) cards or so:shrug:

PLEASE provide a link to more information for this, I was getting this during my testing. I was also seeing the "attempt to write to read-only memory" BSOD as well. Since I have 3x video cards this might make some sense as to why I was seeing it. Now if I could remember if it was when I was clocking my memory or my CPU up. I think it was CPU, but I can't remember. So please provide a link!

Someone asked me about my CPU, since it looks like I got a lame one and I can't push it past 3.6GHz even under water cooling. Could be because I have 4x2gb memory modules - not really sure.

Thanks.

I am struggling with my X4 920.

DFI LR 790GX-M2RS Jr
2x1GB Kingston "Value" DDR2-800

No way possible to get HTT > 240 from Bios.
Well, after a couple of total bios/mb lock-ups I tried one Ballistix DDR2-1066 stick which made it possible to reach HTT=256 (3.58Ghz). Had to "bump" the VCOre to 1.475.
Bench-stable at that speed also.
Edit:
I have tried all types of "tricks" both in Bios and to use AOD to get HTT > 244 (black-screens/noboots after that).
Will probably get some new sticks to go for higher HTT (if it helps). I suspect this is a bios issue as it has no effect to set timings manually to very slow speed (1:1, 6-6-6-18 23 2T) to exclude ram from OC-issues.

I am very disappointed by the DFI mb.
I really thought "lockups" like this was something not to be expected on newer mb.
(Reminds me of Socket-A/754/939/478 days).
Only way to get the board to boot again was to remove/reinstall RAM, CPU and remove Bios-battery. (the "clue" was to reinstall the CPU to get it goin' again).
All newer boards (both for Intel an AMD) I have been used to lately are able to reboot after max 3 "stuck loops".
Or at least reboot after pusihng *external* reset-button (at least the latter is to be mandatory for a board of this type/price from DFI).

This is the highest stable so far (unimpressive to say the least). :(

Hmmm have you test any new bios?, Sounds wierd if you cant go higher....My Dfi 790FXB Dark works very well, do you have all settings shown in bios?(F9 if i remember right) , have you tested to change ram speed to 600/800?

Maybe you can get some good info from this thread.. http://www.xtremesystems.org/forums/...d.php?t=208340

And also AOD dont works so well for me... so bios clocking is best.

nm you are vapo I thought it was air..........but a screeniw with aod/cpuz and maybe another showing voltages would have been cool to prove the voltage......but again nm.

here you go, with hotfix download

http://support.microsoft.com/kb/952681

there are a few of us having this problem, including the 'write to read-only memory' also the 'write to page file in unpaged area'

4.68GHz @ 1.52v! Screenshot stable, but I thought I grabbed one before I tried to up it further! =o/ bummer.

Yes, yes, and yes.
Did I play against or with you sometime? (Bad at remembering names)

yeah you played with me and a couple of buds in VS. mode.

i just got my 940 its a 0849apmw on the dfi lanparty 790gx jr and im trying to dial in an overclock, but have had misc problems looks like the beta bios 12/30 that i have install will not allow me to change the multiplier and just stupid little issues with the bios like not being able to disable c&q is annoying ive been able to boot at 3.9 and temps were really good (under 40 load) but i think my ht was too high ive set my ht down to 1.2 and seeing if 3.75 is stable and working my way up to hopefully 4 :( well ill post screenshots later depending on what happens...

Thanks for answering. :up::

I have tried every trick "in the book"... and read all relevant threads I could find (including the one you link to).

Either the CPU or MB has a "HTT-wall". I vote for the latter.

I have not tried any beta-bios, as one of the "AMD-boys" on "diskusjon.no" (norwegian forum) recommend to stay away from beta bios for this MB (he have tried, and he have several MB's and Phenom II) :)

I will try some other (better) RAM, and maybe get another MB to check whether it is the CPU or DFI MB that is the "show stoppper", as I really had high hopes for my X4 920.

I have been "spoiled" with numerous OC-sessions with Intel Core2/Quad rigs that hits up top 100% OC, in average around 40% I think. The best results in the cheapest rigs. :D

And maybee I was a "cheapo-boy" choosing to go with 920 instead of the little more expencive 940.
With 940 I would "only" have to increase MP and VCore to get the max... preferably 4Ghz.

A few observations:

Enabling red mode by far increases power consumption more than anything else...more than vCore...more than vNB...more detailed findings later. Considering the trivial performance increase red mode offers and that we're primarily thermally limited, I currently recommend staying green mode and go for higher clocks.

Example, going from green to red at 1.300V/1.175V/3.0GHz raised CPU draw on the 12V rail from 2.8A to 4.0A (idle). Going to 1.425V/1.250V/3.6GHz barely even matched that increase--instead going to about 4.1A if in green mode. 1.425/1.250/3.6 goes to 6.0A if in red. I'm making a more detailed thread about this and re-running all tests. I'll post in the coming days.

hmmm red mode? is this the button in AOD in the top right corner? anyway im interested in what you find.

I am a tad pissed off now. The Phenom II 940 is only 235 now. The Phenom II 920 is 195. Well, I guess I can't really complain when I got mine so cheap.

yea i saw that didn't they say earlier that it would drop to 225? anyway its a nice drop just after the chip was released and maybe we will see more when am3 comes out but im not counting on it anymore. also i thought this phenom II 940 review was funny: another person saying their tech level is high.

Pros: Played a week with this chip and best (everyday practical use) I got is 3.4GHz stable (64-bit Prime, OCCT, etc...) using 64-bit Vista ultimate. NorthBridge multiplier 10x, NB volts 1.325V. CPU Vcore 1.4375V, CPU multi 15X and HTT 226MHz. Memory at 800 (not 1066). Temps at full CPU load around 56C using Antec Sonata III case (case fan at middle speed setting) and Xigmatek HDT-S1284EE heatsink.

Cons: Could not get 2x 2GB Kingston HyperX (PC8500 5-5-5-15) work completely stable at rated speed. Newest motherboard BIOS (0802) helped a bit, but still random BSOD's... using 1066 memory speed also increased CPU temps by couple degrees and reduced highest stable CPU overclock to 3.3GHz.

Stock heatsink run 10C hotter than the Xigmatek. It is only good enough for the CPU at stock speed/voltages... Don't expect to overclock with it!

Other Thoughts: Seeing all those report people reaching almost 4GHz stable (really?) with air cooling... I'm sceptical. I tried my best and didn't get even close! What gives? Worse than average chip???

Using Kill-a-Watt power meter the setup below use 175W at idle (no Cool'n'quiet) and 274W at full CPU load (Prime) With Prime and 3DMark running together peak I noticed was 340W.

My rig:
64-bit Win Vista Ultimate
ASUS M3A78-T
Phenom II 940 (0849APMW)
Antec Sonata III with 500W Earthwatts PSU
2X2GB Kingston HyperX 1066 (5-5-5-15, 2.2V) @ 904 5-4-4-12-15, 1.9V
Sapphire Radeon HD4870 1GB (810/1000)
WD Raptor 74GB for system
WD 750GB for data
3DMark06: 15900

He's got the same stepping as me. I'm starting to notice a trend here with APMW.

Problems Right Now with Current Bios for ALL D.F.I AMD Boards with New Phenom II. Taiwan is working on this and I am Testing a Alpha Candidate right Now For D.F.I that will bring universal Code and layout for all D.F.I AMD Boards ...................Be Patient its being addressed as we speak:up:

Take my advice DO NOT Push to Hard with Current Bios. Voltage Tables in Bios Need serious attention much more so on 790FXB Models

he also is wondering why running your ram faster makes your cpu hotter and why the stock cooler is not as good as his s1284ee.

that is real strange i have 4 x team c3 and never had to increase the voltage on msi k9a plat / asus m3a78 or m3a79-T which is my current board.

Can someone explain this red/green mode?

The Red/Green mode is related to AOD (It's the ring in the upper right corner of AOD). In Bios it's turned on/off with the "CPU Tweak" option, and from my experience it does add alot of heat without much benefit.... ;)

On another note.... I've been playing with my 3.9Ghz OC tonight and I'm really starting to think I can get this stable... :D

Here's a SS with a bunch of benchies including CineBench which is always touchy, but seemed to run without problems using these settings. :up:

http://i30.photobucket.com/albums/c3...0120_WowSS.png

JUST A WARNING!, If your running on Air you probably wouldn't want to run your CPUvid @ 1.6v's, but as you can see from the SS my "redneck" water cooler keeps temps pretty well in check... ;)

I'll work on my 1Hr OCCT verification Oldguy, so get ready.. :yepp:.... :D

Ugh, forget it:shakes: Everytimer I think I solved it somehow it happens again anyway.

First I had random 0x00000124 issues. This seems to ber solved now. However I still get the pop-up notifying that ati driver has stopped working and is recovered. This can happen 5 times in a row and BSOD into 0x00000116. And just yesterday it got worse and just BSOD'd into 0x00000ea.

I tried :banana::banana::banana::banana:loads of things, I reinstalled the driver a few times, I chose not to install CCC a few times, when it was installed I chose to close it before gaming and I even tried to install ATT instead of CCC...:shakes: Im done and Ill re-install XP x64. It's a shame since I wanted Vista for DX10 but this way I cant use it anyway.

Great job M$, luckily they're already testing Windows 7 while it seems that this particular issue (which happens to nVidia too btw) has been there since the Vista beta!:down:

Then to think a few years ago everyone was like avoiding XP as much as possible, well, I embrace it right now:cool::yepp:

My chip required a slight boost in voltage to get 4.68GHz stable enough to run a PI. No optimizations with this run, just a straight PI run so I feel it could still be much lower!

What cooling Man, I would assume your sub-zero right?

Awesome clocks reguardless... :up:

An AMD, under 15 seconds SuperPI... SWEET!! :D
