Hi all...

Been overclocking the last couple of nights with the rig (in sig lol)

Ive hit a wall and Im not really that good at overclock (quite useless actually) so just after any more ideas of what I could do etc etc...

So after lots of testing I could get 18x200=3.6ghz I got stable with cpu1.4125v.
To get 18.5x200=3.7ghz stable I used cpu1.475v.

I tried lots of different things to get it stable at x19, including bumping up all the other voltages, bumping the NB speed to 2.6ghz (this is where I stopped) as I heard this could be why its crashing... and even at cpu1.525v it still wouldnt run stable... At that voltage it went no hotter than 47degrees.

I then tried a couple of 18x213=3.8ghz, I tried this at lots of different settings but could never get it stable.

So my BIOS has all these voltages:

CPU Voltage
CPU/NB Voltage
CPU VDDA Voltage
DRAM Voltage
HT Voltage
NB Voltage
NB 1.8v Voltage
SB Voltage

Could any of you tell me the limits of each of these? And what ones would help with Overclocking???

Id be happy to hit 3.8ghz stable Im not that ambious..

Cheers

Thats really odd that its taking 1.4125V just to get to 3.6ghz. I can get this 720 with the 4th core enabled to 3.6ghz with only 1.375V.

If your using the X to overclock you should not have to raise any of the other votages. Have you got the latest bios on the board?

Ill check the BIOS, but I had to get the lastest BIOS just to get the 955 working and that was only like a month or two ago... But Ill check.

Thats what I was thinking, I really hope I dont just have a dud.
 
I didnt have the lastest BIOS, so I updated to the newest one 1302 or something.

But did some tests and still only got 18x200 stable at 1.4125v same as before, I then went to sleep lol. So yeah still think Im back to square one..

What do you guys know about RMA's? Can I just send my chip back and get a new one?

What kinda temperatures you getting on the chip? You should probably try using the multi to overclock if you arent already.
 
I would probably reset the bios and start from the begining again. With the memory at default. Set the CPU voltage to 1.375 or 1.40 and start bumping up the multi and see how far you get.

The memory at default is wrong, for some reason my board sets it to 1333 and something like1.9v and random timings, So I set all that myself to what it actually is.

The highes the temp has ever been under full prime95 (64bit) was 46-47degrees, and that was after a wee while and under 1.525volts if I remember correctly...

Im annoyed cause I was reading a TomHardware overclocking review on it and they with stock coolers were getting the multi up to 19 etc and their temps were 59degrees and they were stable... And Im pretty sure that was only at 1.5volts.

I think he means set it to default, as in the stock clocks and not overclocked.
 
Well it defaulted out last night when I flashed the BIOS, Ill test again tonight and see if I can now get futher cause of the BIOS update.

Does anyone know the maxium safe voltages on the board/chip? So at least I know where I can experiment too.

Also the RMA thing? How easy is it to just return chip?

Thats what I mean, for right now leave it at 1333 and what ever voltage and timing it defaulted to. That is the boards/AM3 processor default setting for memory. 1600 is considered overclocked. You might even have to bump up your CPU N/B voltage for 1600(not the boards N/B) Just till you get your CPU overclocked, then bump up your memory.

Plus for 1333 or 1600 you need to have one stick in each channel. One in the red slot and one in the black slot. Not side by side in the same color slot. And run them unganged.

Like I said, start from the begining again and just work on you CPU first with everything else at default.

Whats this??? But then they wouldnt be duel channel?

Someone suggested to me to run my computer at stock for ages... So at 1600 and 9-9-9-24 timings and CPU at stock I ran it for 6 hours on Prime no problems, just to be sure my starting point was stable...

But ok ill give it a try, so you reckon split up my ram into single channel (wont that drop performance by heaps?)

It will still be Dual Channel. Phenoms have two 64 bit memory controllers, you will still be using both for a total of 128 bit (no performance difference). On a Phenom Single/Dual channel really has no meaning anymore unless your just running one stick of memory. And one stick a channel is recommended by AMD for 1333/1600 because of the load on the memory controller. Your really not even suppost to run four sticks at all if your running at 1333 or 1600.

Mine is setup with one in each channel, bios and all programs says its in Dual Channel.

Edit
One caveat: the Phenom II only supports 1333MHz DDR3—at least, officially—with a single DIMM in each memory channel. With four DDR3 DIMMs, 1066MHz is the standard. Such limitations are nothing new, of course. Previous Phenoms have long supported 1066MHz DDR2 memory, but only with a single DIMM per channel.
http://techreport.com/articles.x/16382

let us reiterate what we found from AMD about the DDR3 memory controller on the AM3 Phenom II processors. The official line is that the integrated memory controller on current AM3 Phenom II processors only support a single DDR3-1333 DIMM per channel
http://hardwarezone.com/articles/view.php?cid=2&id=2807

Officially the Phenom II AM3s support DDR3-1066, and even DDR3-1333 as long as they are limited to 2 bars for the moment (1 per channel). In practice DDR3-1600 is also listed in the bios and this mode works according to our tests.

So do you think this is the reason for my instability at overclocking?

Also so what happens if I get two more sticks like I was planning too? I was planning to run them all at 1600??

Dont really know, like I said I would start back with default setting. Disable CoolnQuiet, raise the CPU Vcore to 1.4V and start bumping up the multi and see how far you can make it before it gets unstable.

You still can on most, you might have to bump up the CPU N/B voltage and run the memory about .1 higher, like at 1600 it suppost to be at 1.65V, you might need 1.70/1.75V.
 
OK well Ill give it a try tonight....

So do you reckon I could just return the chip? Or do you actually need proper reasons lol.
 
I dont know, opened and used. I kinda doubt it but you could see what they say. You really dont know if its the CPU or board though. I've had the same CPU in two different boards and it would clock better in one then the other.

Are you using the full 8 pin CPU power connector?

Thats the top left one right lol... Then yes.... This board is ment to be like one of the best overclockers.... grrr nothing seems to go right...

What maxium voltage do reckon I would be safe at?
 
Ok so interesting night....

Firstly I reinstalled the ram so that each stick was in its own color (installed in slots 1 and 3)... Installed a 80x80x15mm fan that now blows cold air onto the back of my motherboard where the CPU is...

In BIOS I set everything back to [AUTO] etc... Ram in windows showed as 1333 9-9-9-24-33 T2 and single channel.

Started Overclocking, went really well... with voltage on [AUTO] (showing 1.35v in CPUz) I managed to pass Prime for 20 mins at 18.5x200...

Heres where it got interesting and odd...

Tried 19x200 heres what happened:

[AUTO] (1.35v) = Booted to windows but crashed in Prime.
1.3625 = Crashed at Windows loading screen (green bar that loads up windows) (odd isnt it)
1.3750 = Same as above
1.3875 = Got past the windows loading screen was about to load desktop the BSOD
1.4 = BSOD as above
1.4125 = BSOD as above
1.425 = Booted into Windows, crashed on Prime
1.4378 = Same as above, crashed on Prime
1.45 = Almost loaded desktop the BSOD as before (very odd)
1.4625 = Booted into windows but crashed on Prime
1.4750 = Same as above

Started to get tired so just tried 1.5v and it crashed on Prime as before (but lasted to the 15 min mark.

So does anyone know whats the story with the random crashing during windows loading??? Like if it can do it everytime at 1.35 (AUTO) why crash when more volts???

Everything else was at stock.... so whats the next step??
 
Yeah I do... I think thats what helped last night with the stock voltage OCing... It has an "Unleashed" mode should I enable that.
