Thats what I wanted to see, Good stuff man.
What speeds was your NB at on that everest run?

What speeds was your NB at on that everest run?

Damn just realised I didnt expand a cpu-z for memory stats.

NB was at 2.8Ghz

 

[cdawall]

2 x 2GB @1600Mhz 7-6-6-20-1T is'nt that bad, is it..? I'm from the UK...

What you got anyway...?

the stuff i have does 7-7-7-21 @2ghz

but @1600 its not that bad

Which ones..? Full spec incl Voltage used..? How much all incl to ship to the UK..?

What about the voltage? My RAM is certainly getting bottlenecked by the NB, but I can't even get it to run at 2.4GHz stable without 1.45V (Seems insanely high from what I've seen..) on both the CPU and NB.

 

[keenan]

I use 1.4V for 2.6Ghz (13 x 200) and 1.45 for 2.8Ghz (14 x 200)

1.2V being default, so for 2.8Ghz I add +0.250V to CPU NB VID Control

Go into the bios and set your voltage first, then save and exit, then go back and set your desired speeds...

 

[somestranger26]

I can get it to boot into Windows with anything from 1.4-1.5V at 2.6/2.8GHz but it will lock up or reboot within minutes, and I've verified the NB VID is being set correctly with AOD. I'll try what you suggested anyway though.

 

[keenan]

Are you running with the unlocked core or just normal..?

 

[somestranger26]

Just the 3 cores, at 3.4GHz (stable at 1.425V, but the NB wasn't stable unless the values matched)

 

[keenan]

Have you tried unlocking the 720BE to full X4..?

 

[somestranger26]

My motherboard supports ACC but not the core unlock (and ACC just makes the overclocks less stable)

 

[keenan]

Which bios are you using..?

 

[keenan]

Pm me your email and I'll send you a modded bios for your M4A78T-E

 

[somestranger26]

PM Sent -- My NB seems to be running stable (~30 mins on P95 so far) at 2.6GHz now that I disabled ECC and CnQ so that must have been the issue. A fourth core still sounds nice though .

 

[keenan]

OK, I've emailed you the bios... this bios is only for M4A78T-E

Now, after you have flashed, clear cmos, go into bios and set all your settings the way you like them, dont touch ACC, CnQ or overclocking....

After you have rebooted, go back into bios and disable CnQ and set ACC to auto, reboot...

Now at the post screen you will have a Phenom II X4 20...

Just boot into windows at stock settings and see how it goes...

 

[somestranger26]

Using the defaults, disabling CnQ, and setting ACC to auto, the motherboard won't POST. It just keeps trying to spin up my graphics card/cpu fans. Bad 4th core, I'm guessing?

 

[keenan]

Whats the code on your cpu..?

 

[somestranger26]

Stepping: RB-C2
Revision: 00100F42h

Or is there one on it physically you need?

Also, 2.6/2.4/2.2 are all unstable with the new BIOS, and I get an error message at boot:

"No DQS Receiver Enable pass window found
DQS Rcvr En pass window too small (far right of dynamic range)"

 

[keenan]

This one here...

 

[keenan]

It might just be a bad cpu mate, my stock voltage is 1.3V and I can get upto 3.4Ghz with it...

Maybe just flash to the newest bios from asus and see if it gives you more stability...

 

[somestranger26]

0904DPBW is the code on the cpu. Yeah, I figure I just got one with less headroom, but the NB not wanting to overclock at all is really annoying, since every 200MHz ~ 500MB/s R/W on the RAM.

 

[3dsage]

You got a winner dude, it should unlock easily and clock pretty well to.
I have a 0904 DPCW and i'm hitting 4.07GHZ max at 1.575V on x4cores.

Have you tried giving it at least .175V+ on the NB VID you should be able to run x13 multi with taht.

Not sure it's a winner, since it won't post with the fourth core "enabled" with the modified BIOS.
As far as the NB, keenan said its default is 1.2V, so I'm running it at +.25. (Mine sets the actual value, not relative ones like +/- X volts) I just updated to ASUS's latest BIOS and it didn't perform any miracles for 2.6GHz NB, but it did fix the artifacting I had running the sideport memory at 1333... Also, I got my CPU working at 3.5GHz, but nothing above will work even with 1.6V (+.15V not letting me go up even 1 MHz is hilarious to me )

My BIOS has CPU, CPU/NB, CPU VDDA, NB, and NB 1.8V voltage settings. Do I care about the last three at all? I've never seen someone talk about changing the "VDDA."

Strange, Maybe it has something to do with the fact your using the onbaord GFX IDK.

But yes anything over 1.575 on this cpu for me does nothing watsoever Need to get some DICE or Water, the chip probably needs some lower C's.

As for the the NB you should be able to run x13 multi (2.6GHZ) give it more juice

I can run x14 multi on the NB but its really on the edge of stability and it BSOD randomly, so I stick with x13.

My settings are
NB Voltage: 1.4V
NB Vid: I added + .15

I think the cpu overclock was causing the stability issues earlier! I turned everything back to stock and 3.4GHz at 1.425 caused a crash after about 2 hours in P95. Dropped it to 3.3 from 3.4 and I'm trying 2.6GHz NB at 1.425 again. I don't think I'll try anything past 2.8 if I get it working, since that seems to be where the bottleneck ends.
