So, got a new 1055T and I'm trying to squeeze all I can out of it, figured I'd start my own thread for it rather than use the larger OC thread, givn that's more for showing over stable clocks rather than help getting there, plus its in the wrong forum :3

Anyhow, I started off with this:


A cpu that sits around 41C on 1.33V basic. I went into the bios, disabled C1E support, K8 Cool&Quiet control and Core Performance Boost (TurboCore?)

Got as far as the login screen, entered my password and my PC reset. Which is odd, since everything should be at default settings apart from those things, which are all power management and shouldn't affect it anyway. Pics of the bios below, the second one shows the voltages, though I have them at auto for now as I have no idea on what to set any of them at, and not sure when I would go about changing any of them.

Still, I did notice that it seems to think the CPU clock ratio gives me a speed of 3300Mhz, which is what I would get if I had a 16.5 multiplier. But my chip's locked to a 14x multiplier, so I've lowered it manually to 14. Also, the ram seems to be underclocked, as it is this and supposedly 1600Mhz, but ram speed isn't important as processor speed and stability right now.

So, I keep everything like that and just nudge up the bus speed 5mhz at a time? I know I'll need to lower the Northbridge and HT link frequence multiplier down because they can't be allowed to go over 2000Mhz, right?

Also, with the normal clocks, AMD Overdrive and coretemp are correctly reporting the 14x multiplier at stock speeds, but CPUz seems to jump between the 14x and 4x multipliers, which is a little weird.

Edit: Just as I posted that my PC reset, still on the stock clocks >_>
I'm going to try running prime some more, but I don't see how it could be related to temps. Not enough voltage, perhaps? Though I would have thought the mobo could at least manage to get the voltage right at stock :(

Edit2: And now its done 15 mins of prime 95 completely stable, TMPIN1&2 hitting 44C. So its obviously not a temperature thing causing it, VID is 1.325 according to AMD Overdrive.

Edit3: That was 15 mins of the cpu only stressing one. Started a blent test, instant freeze. About to run memtest.

Edit4: Noticed the ram is being reported as: Ram: 533Mhz (DDR1067) CAS: 7-7-7-20 / DDR3. I know since its running underclocked, it tightens the timings, but I just tried setting them manually:

Got to windows, logged on and it froze again. Argh!

Well, at the moment I've turned the focus away from overclocking, towards simply being stable at stock speeds. I'm getting crashes and reboots in windows. I just set the mobo back to the factory defaults and it froze on the 'starting windows' screen. Rebooted, got into windows, and it died when I started a blend P95 run.

Setting ran to 1.65V, other voltages are as seen in this pic: http://img824.imageshack.us/img824/479/bios2.jpg
 
Yup, I flashed to the latest bios a couple of hours ago in case it would help, it didn't.

Right, it froze on the 'starting windows' screen first time, rebooted and into windows, running a prime blend test now, and its not crashed this time! \^-^/

So, I'll give it a little longer stressing, but looks like I'm stable enough to start overclocking. Thanks for the pointers, though I'd have thought that the mobo should have been good enough to know what voltage to run the ram at itself :x
 
Hmm, I have a pretty awful chip then? Drat it :x

Ram set to the lowest multi, 4x, making it 840Mhz, and set the NB and HT link multipliers to x9, CPU to 210, making those two 1890Mhz, going to stress them now. But given my massive Vcore, I guess 3.5 is a more realistic target than 4.0Ghz. Oh well, such is life.
 
Its 1.475V according to the bios, that's what its always been at, showing as either 1.325 or 1.3v in windows programs.

Testing at 230mhz now.

And 900 seconds, pushing 57Gflops, which is probably good. 240 time! I've lowered the HT and NB multi's down to x8, so they are at 1920Mhz, just because I only want to be overclocking one thing at a time :)

Right, I just ran the burn test at 240Mhz, and time went back up to 955 seconds, 49.5Gflops. I'm assuming this is just down to me lowering the NT and NB speeds? Test finished stable, so I guess so :p

250Mhz finished in 834 seconds, 61Gflops

Tried to set it to 260Mhz, and I get the message on boot:

The system has experienced bood failures because of overclocking.
Last settings in BIOS setup may not coincide with current H/W states.
Current CPU Speed: 14.0 x 200Mhz
Current Memory speed: 1066Mhz
Current HT Speed: 2000Mhz

Press DEL key to enter the BIOS setup, or press any rest of keys (sic) to continue.


So... more voltage needed, or what? Its a rather cryptic error which tells me absolutely nothing :x

Edit: After messing around with lots of voltage options, pushing up the NB by 0.25v has got it booting again. Huzzah!
Edit again: Wait, no, I forgot to set the cpu freq back to where it was before, still no boot :x

Got it to boot!

CPU Freq 255Mhz
NB & HT Link: 8x multi = 2040Mhz
Memory clock 4x = 1020Mhz
CPU PLL voltage: Normal = 2.5V
DRAM Voltage: 1.650V
NB Voltage Control: 1.320V
Sideport mem volt control: Normal = 1.6V
NB/PCI-e/PLL Voltage Control: Normal = 1.8V
CPU NB VID Control: +0.050V = 1.2V
CPU Voltage control: +0.125V = 1.4500V

(Sorry for all the posts, just keeping things seperated)

That's it with the voltages I mentioned above, 3570Mhz, and touching 60C. Given 62's the cut off, and it won't boot with lower voltages, I guess that's about it for the overclocking, at least of the FSB? Especially since the burn test finished much faster at 5mhz less :x
 
I'm using the Thermalright IFX-14. It did great for my E6600. As for the VID, that's what the mobo said to use. I'll snap a pic of my current voltages in a moment, but I'm not sure how much higher I should raise any of them, especially since I'm currently hitting 60C in stress tests, though then again hopefully I won't be under 100% stress too much.

I'm not sure how to get further than where it is right now. Its not stable trying to get it over 3.5 and I'm not sure what voltages to up to try and keep it stable.

I'm currently looking at buying another couple of fans to help cooling, and maybe replacing the smaller hard drives with larger ones so there's less, meaning more cooling for the heatsinks.

i got mine up to 4.0 gig. it passed 20 round of linx and 5 round of intel burn on max but was failling occt

so now im going to settle for 3.8 at 1.46vcore i think

what bios settings do you have now?

Those are all the settings I have. I'm pretty certain that's how I have it at the moment. I think I did manage 3.55Ghz stable, but it needed a fairly large voltage push, and the temps were getting rather high, so the 0.05Ghz boost didn't seem worth it. That said, it was a couple of weeks ago now, hopefully the thermal paste has settled in and will give me a little extra room as well :)
 
I assume the nb temp you're talking about relates to the NB voltage control in my bios, and not the CPU NB VID control.

The annoying thing is, I don't have a clue what a lot of those voltages are, so don't have a clue how far I can raise them :x
As for the multiplier, its x14, the max I can set it to. Also, my memories heavily underclocked (Its rated at 1600Mhz) because it wasn't happy with being raised higher either, it wasn't stable.

1500Mhz isn't too bad, mine's at 800!

And you VID is at 1.325? Interesting. I should be able to whack that up a fair ammount then, as my actual NB voltage control is about where you were.

You say you have exactly the same mobo, any chance you could take some snaps of your bios settings? Or type them out if its not too much hassle? :D
 
I'm heading off to sleep now, but I really appreciate this, over the weekend I'll see if I can push the cpu any further, hopefully it'll be a cooler weekend as well XD
 
Thanks for that, should be a great help!

Looking at the CPu voltage values, yours seems even higher than mine at base! (1.45-0.125 =1.325v for me, compared with 1.475-0.05 = 1.425v).

Also, just checked on Corsair's website and it seems that my memory has been tested up to 1.8v, so I should be able to crank that up a little as well to get it stable at higher clocks, I was just a little worried by the bios number being such a warning colour XD

Only problem can see now is heat, but once my plans for a cooler case are put into action, it should be great. Cheers :)

hello iviv

the reason why cpu vcore is high is becuase was going for 4.2 but when i settled for 3.8 i havnt put them back down again.
Click to expand...

Actually, I mean the initial vcore. Yours is only increased by +0.05V and is running at 1.475V. Mine has been increased by +0.125V yet is only running at 1.450V. Meaning that your CPU's taking a lot more voltage at stock than mine.

Also, OCing outside of the case seems rather counter-productive, because a speed that's stable outside of it won't nescecerily be fine inside because of the increased temperatures. Seems easier just to find the max inside the case.

Anyway, just increased the ram voltage to 1.695V, NB voltage control to 1.340V and NB VID control to 1.2250V. Frequece to 255 making 3.57Ghz, off to test it now.

5 mins of prime95 stable, and intel burn test 5 runs (max memory) stable. 63 GFlops :) TMPIN1 hit 54C while TMPIN2 hit 61, so its getting close to the temp limit.

Bah, headache time again. Got the CPU freq up to 265Mhz stable, resulting in 3.71Ghz. But I've now been aiming at getting the ram up to more reasonable speeds. Setting the memory clock up to x5.33 (1412Mhz) which is the next one up from x4, but just can't get it to boot.

DRam voltage: 1.755
NB voltage control: 1.360V
CPU NB VID: 1.275V
CPU voltage: 1.450V
 
*forum used as personal notepad*

Just managed to get into windows by:

Disabling internal graphics mode (Not using it anyway)
Dropping northbrifge and HT link freq multis ddown to x8 each
DRAM voltage 1.770V
NB voltage: 1.360V
Sideport mem voltage: 1.450 (Was sitting on normal at something like 1.7V)
NB VID: 1.275V
CPU voltage: 1.475V

Though didn't stress test like that, as I just saw your post. Will try getting the ram voltage down and nb up a bit :)

Edit: DRAM voltage down to 1.665V and NB VID up to 1.300V. Got into windows fine but froze as soon as I started running the prime blend test. Now trying 1.680V and 1.325V. Won't even get to the login screen now. Goes through all the 'starting windows' then restarts. More ram volts needed, I guess.
