Ya, and it loaded into windows. I tweaked a lil with AOD to further the OC attempt. Went to open CPU-z and boom. No post just powered on.

I hope you have ordered Ram that is the regular low profile sort because you have trouble using the black and yellow slots closest to the socket with the TRUE unless you get and modify the S-clip - but then you have to use the stock retainer and you don't get to bolt it through the board and this is less that ideal when it come to the contact pressure you get.

I got an SI-128SE after I found that my TRUE wasn't ideally suited and it just works with my G.Skill PI which only have moderately tall heatsinks.

So you guys are still getting very high overclocks with a Phenom II WITHOUT having to rely on ACC right? I'm asking because I just ordered a PII 940BE and Asus M3a79-T mobo with OCZ DDR2-1066.

i wouldn´t call it very high. i´m stuck at 3.6ghz, but it may also be my cpu :shrug:
acc is definetly not working...

Yea, enabling ACC results in a no-post for me with it set on Auto.

Worst thing I did was to enable ACC. I changed ACC to AUTO and the damn thing wouldn't even post. I had to clear the CMOS via jumper.:(

I can do 4.0Ghz with 1.6V on water cooling Super Pi 1 Meg stable and windows stable.

Sweet spots are 3.6Ghz at default vCore to 3.8Ghz with 1.45vCore. Yet to do 3.9Ghz run.:ROTF:

ACC thats the thrid person to try that on this including me.

I did 3.9ghz at 1.55 volts :shock: temps where to high 50C idle, 63C load. today but my windows was all buggy so I reinstalled it.

anyone turn off cpu tweak I gained on my scores with it off :hehe:

I'll have to play around with cpu-tweak, I didn't even bother touching that option while I was in the bios.

And yeah, voltages from 1.5 and above seem to really start to add heat quick.

I'm sure Asus are working on a new Bios to fix any problems.

I can't wait for my 940 to arrive :D

Got the Phenom II on my board now. Ths speed difference between this and the 3500+ is amazing. No surprise there :P

As far as overclocking is concerned though, I'm not sure where the memory divider is set - if it needs to be.

I'm starting to think that the memory clock is entirely independent of whatever I set as Bus Speed/HT multiplier/Clock multiplier. I just set a memory frequency and it sticks to it?

I have some serious problems with M3A79-T Deluxe and Phenom II 920, and I think it is related to some bad motherboard settings on my part.
I can't get the system to run stable at all, not even with stock speeds and everything (but memory voltage) on auto.

First off, ACC and AOD isn't working well att all. After reading here I can conclude that I'm not alone with those problems, so let's skip that.

After hours and hours of tweaking (who at Asus came up with the brilliant idea to NOT write out standard voltages in BIOS?!) i finally got the system more or less stable with the following settings:

http://pici.se/pictures/tRrQxYQVN.png

http://pici.se/pictures/QMpjauDtA.jpg
NB freq is about 2200MHz and mem about 950MHz (800MHz original, not 1066).

With those speeds SuperPi 1M runs at about 20sec, from what I can read this is pretty norma for about 3.4GHz.
However, in 3DMark i get ~ 4400p as CPU reslut which is almost 1000p less then other results at the same speed.

Overall the performance is much worse then with my old E8400 @ 4GHz. I realize that the E8400 was considerably faster with singel and dual threads, but even in programs that favors multicores, such as 3DMark, my results were better before.
My GFx is a GTX 260, with the old system I got about 17300p and with the new about 16400p.

Right now I feel like I've spent ~$525 on absolutley nothing, any tips you can give me?

You don't need to worry about voltages as much as you are. Many of the options other than vcore, vnb, and ram volts can just be left at auto. Worry about finding the overclock for your cpu before trying to overclock everything together. Try working with just the multipliers first, but remember 18x and above don't work correctly.

Multiplier might be hard as I'm using a 920.. ;)

At first I tried exactly that, just tweaking vcore, vnb and vram, but that rendered the system unstable at everything above 3GHz..
If I lover the vcore just one notch the system crashes all the way down to 3.1GHz..

I will try to bump the NB and HT doown to a minimum and see how high I can get the CPU again.. Last time I got stuck at around 3.3GHz, though, even worse then the current setup.

I have two temperature probes on my heat sink and at those temps wih 985- the heat sink would get up to 41C. but the heat sink never got farther then 30-32C...:shrug:

as for cpu tweak I disabled it and gained a ton on speed. :confused:

hmm, most of you seem to be able to reach 3.6GHz with around default vcore just like me, but I cant seem to run stable at anything over that speed no matter what voltage I use. Can you show me what settings you have in the bios to get up to that 3.9 range?

I can reach 2.75GHz notherbridge and HyperTransport speeds, DDR1150, but I am limited to about 3.55GHz to be 100% stable on the CPU cores...
01-10-2009, 11:42 AM
Oldguy932

Sorry about that, just took a glance at the screeny and looked more at the bios shot. High htt isn't a problem if you keep your nb and ht link in check. Set the option just below vcore to 1.3v and you should be safe through 2.2-2.3ghz on the nb speed.

Did disabling cpu-tweak have any effects on stability? I still need to figure out some stable setting today or else my first week back at school is going to be spent around the computer and not people. Not to mention I'm going to be installing the Windows 7 x86 beta on here soon when I put a spare hard drive in here.

Disabling CPU-Tweak does not have any effect. The system was posting and getting into Windows at 3.75GHz last night, but not stable at all. Now this morning it wont even post with a speec of anything above 3.6GHz

I found some kind of sweetspot here..
Everything upwards from here creates unstability at some point, the only thing i can do is trade my CR for a lower CL, but from what I saw during benching that made no difference.
Next multiplier for the memory gives a frequency of about 970, that is too much for my 800MHz-sticks.
The NB can take a little more, but the CPU can't. Next step is ~300 as HT ref to aquire the same CPU-speed and higher NB, and that hardly boots..
:)

In the end, I guess I should be happy. It's a decent clock considering I can't change multiplier, and it's rock solid.. Been running dual Prime95 for 2-3h accompanied by looping 3DMark06 without problems. If I apply my 650MHz increase to a 940 it gives about 3,6GHz which is where most people ends up..

SuperPi gives 20 sharp (20.050).

But what is the latency difference between CL at 6 w/ 1T CR and CL at 5 w/ 2T CR? It might be the same overall speed in benching, but if the latency is a lot different then you should pick whichever has the lower latency.

Actually C&Q 3 has 4 default P-states and goes down to .8v, full features allow users to manually set their own P-states.

i did a vantage run at 3.8ghz@1.475v after that i started prime and it rebooted without a bluescreen or something.
3.6ghz@1.425 wasn´t stable either.. core 2 crapped out after 16mins.
acc does nothing for phenom2 at the moment. u can´t enable it...
if u do, u get no post.

Well, maybe it does nothing for you...but that doesn't mean it does nothing for the series as a whole :p:. Have the 790GX asus board and i was getting the same issue. If i changed the ACC setting from OFF/AUTO/ALL/percore the after saving bios setting it would just be blank screen, and i had to shut the comp off wait for the power LED on the board to go out then next power on would be fine. Someone i know that actually hasAsus M3A79-T Deluxe said ACC works fine as well just best to not enable it with the voltage jacked up high, and apply ACC per core. I've been able to squeeze an extra 450mhz from ACC, but it's trial and error to get it to work sometimes.

I've found the same issue on multies 18.5 - 20 when i have mem clock set to 1066 in ganged mode, though 21.5 works fine. Some multi's are flakey on certain boards.

it´s not trial and error here.. even unplugging the psu and waiting a few seconds doesn´t change it. what do u mean with "voltage jacked up high"? i mean acc is of no use if i have to use stock volts to enable it.
what is an extra 450mhz? 3450mhz? or 3600mhz+450mhz? ;)

i´m at 3.7ghz now, 3hrs primestable

seems as oldguy was right, the high multis don´t work that well. or it is the imc that doesn´t like 1066ddr2 at higher clocks.

Can I get a list of stock Phenom II voltages? I don't know what to trust anymore. I'm looking mainly for NB, HTT, etc..

Anyone here has a TRUE mounted? If so, can you post a picture of how it looks?

From what I understand it covers the first memory slot AND must be mounted facing up or down.. Still interested though as the local computershop has one in stock..
