Your cpu will error out "behind the scenes" though and could cause OS or file system corruption. It's best to atleast be OCCT stable. Any less and with prolonged use you're asking for trouble.

I have the same 0850BPEW chip. Mine is easy on NB clocking. Just needs around 1.3V for 2.7GHz. Problem is that my mobo doesn't have option in BIOS to increase it, so I'm stuck to 12x multi at max. and then HTT clocking in Windows :p:
BTW I will try to show 4.275GHz Pi 1M time on AIR soon. I did one but comp hang up while opening Paint :mad:
Use MVSNAP instead.
you can setup screen capture with a hotkey to save desktop as jpeg......no need to use paint and it's done in a fraction of a second so most usually will complete before an unstable clock has time to fail :)

It may add 0.171secs to your Pi times but that just means you need to OC higher :)
Thanks for a good tip :up:
I was looking for something like that!
I'm after this one: Lastviking's 1M AIR record
I've beat it on my lunch break once so there is a hope :)
BTW his result is truly excellent!! Congratz Lastviking :clap:
Wow, that's not bad! Mine seems to give up at around 2.5GHz (booting, blue screen when opening windows) ... I'll try to update the bios (if possible) and see whether I can improve my clocks.
Furthermore, I'll try to catch your 1M on air tonight, again if I find the time. I need to pick up some LN2 for tomorrow ... :cool:
This seems to be the max 24/7 setting for my X4 920 (it will go higher, but too much VCore for my liking).
MSI DKA790GX
X4 920 - CACVC AC 0849BPDW - ***80024
2x1GB Geil DDR2-800
VCore=1.475 (Bios)
Got my new mobo today finally I can start clocking my 920 properly.
Few results with winxp 32bit sp3 on the AOD790GX/128M
3.86GHz stable for ~10hrs, NB was at stock that time

Thanks, chip is an average clocker I'd say. NB does well as long as temps stay below 55°C. Compared to the 9950BE the missing pwm hsf is no big deal anymore. That area stays much cooler now.
Max voltage I can boot the chip is 1.6625V btw but I did not get it stable above 1.6V. Unfortunately HT multis above stock do not work here.
I had a little bit of fun with my new bios. I didn't want to leave anything to chance so I just fit as many cpu benchmarks on my screen as possible along with cpu-z. For everest my only speed under 10k mb/s is my memory read, which is at about 9800 or so.

Same specs as before. Only voltage I changed was my nb volts up to 1.575 and mem voltage up to 2.24. It flies in everything, too bad command and conquer 3 and red alert 3 don't use more than 1 core really... off loading being the host computer on a network would be really helpful to use a seperate core so it doesn't slow down when I get my 50 scrin carriers :eek::D
Edit: And if anyone has some good tweaks for wprime other than turning stuff off it'd be really helpful because my times are slow compared to the ones on hwbot, obviously the 32k because I'm not on Ln2 but my 1024k is only another 8 seconds from top 5 last I checked.
Nice work Oldguy!:up:
Ive a question for anyone as long as you managed to run your RAM at ~DDR1200 and have AOD installed. I'd like to know which settings AOD reads for the 6 different Drive Strength levels and the CPU ODT percentage.
I know for a fact those settings do help to increase your clocking, but I lost the paper of testing from about a year ago. I think I can get back to those faster as soon as I know which settings are used often by AOD/BIOS for default.
Ive had two times soe very good DIMMs which 99% of the times managed to get to DDR1200 without issues... on an Intel platform. However people have no control over those memory controllers which might just loosen/tighten things automatically (or just blow the DIMMs, lol @ 680i/P35:p:). Some guy even hit DDR1400 with only 2.35Vdimm on some DIMMs I had before.
Im seriously hoping to reach around DDR1200, but this will most likely need some extensive tweaking, so if you guys could either post the multipliers for the six drive strengths and the CPU ODT percentage (or just post a ss), I would be very happy:up:
cacvc ac 0850DPBW 80038
Abit AX78 (SB600), beta bios .14
Core: 3300mhz @ 1.35v: 12.5*264
NB: 2375mhz @ 1.3v
Ram: 4*1gb @ 4-5-5-15 2.1v @ 528mhz
HT @ 1847
superpi 32M: 21m 39 in background with film playing.
OCCT 1hr: pass
limited at the moment by motherboard, any increae in v-core or pushing frequency past ~3350 results in ocp cutout.
I am aware there might be problems:p: thats why I mentioned it is not torture test stable. I am not getting any errors being logged and system runs smooth at those settings. However, I currently run 3.8 24/7. I just mentioned it cause it is nice to know it is possible to boot at those settings and even use it as normal. Just shows it can only get better as AMD improves the process.;)
You guys are having too much fun with those setups while i have to wait for my M3A79-T deluxe and Phenom II 940. Darn webshop tricked me into thinking they had both in stock. :( Let's hope i get a good one to make up for the time i have to sit on my hands...
for all fxb-m2rs|h owners. try the new beta bios. seems a bit faster and consistent.

Anyone have better score with air and retail prosessor ?
I bought today Asus M3A79-T Deluxe so i hope i get more MHZ and more stablity with 24/7 OC :P
My result: http://valid.canardpc.com/show_oc.php?id=500239
At work and don't have the screencaps posted..
It was on 1.39v
Any help to you?
http://www.aijaa.com/img/b/00664/3539971.jpg
Nice clocks there... what temp did you have on the core?, and what vcore?
http://www.bandwidth.se/imgs/nouser/446617ba6fc07.jpg
This is max for me with Ixus shot when it looked but i got a screen from windows @ 4364mhz the multi before i changed to 4466mhz. So i think i can make a valid if i need it :) , i can post the 4364mhz if you want to see it.....i´m using low vcore becuse my cpu dont like high vcore...about 1.536v
Thank you! Is it (almost) stable though? Might be important-ish:p:
Anyway, that's exactly what I need. Weird though as I read SPDTool, it says
?
2x
2x
1.5x
1.5x
1.5x
But from what I remember slightly is that lower DQS and Data strengths gained me quite a bit. However, just like yours, that was one with 1GB DIMMs, Addr and CS Drive strengths do need to be higher with 2GB DIMMs, makes sense.
CPU ODT, makes almost no sense. Nothing to find about it either:( Anyway, thx again, that's quite usefull:up:
I will need to put my PC into Fridge to get these clocks :p:
Good work guys!
I'm back benching on saturday. I have new toys now!!! New 24'' LCD to better see the clocks and another HD4870 512MB to warm up my test chamber!
:up:
If all goes well, im planning to push a 920 on DICE sunday. With a little luck I might get to see the highest 920 clock yet. It will allready do a unstable 4.0ghz on mid range air cooling and the board is good for well over 300mhz HT.
