1055t OC help

[jthunderloc]

Bound to come up sooner or later

new to OC'ing AMD chips, OC'd several intel chips along the way. I picked up the 1055t w/Gigabyte 890PA a few hours back and am trying to hit 4ghz.

voltage was set to 1.475 from the factory, Coretemp showed a VID of 1.350. I hit 3.4 at 1.35 (voltage fluctuates a lot, never exceeding what I set in the bios but at 1.35 it usually ran at 1.22, perhaps due to C state)

the few guides I ran across with older phenom IIs only talked about adding voltage to vcore and CPU-NB, I saw one mention of adding voltage to the CPU PLL with a high bclck(or whatever AMD calls it). I'm currently at 265bclck at 3.7ghz/1.475vcore, stock voltage to everything else and temps look great briefly hitting 40c under load running linX with a Coolermaster Hyper 212. dont remember exact NB, but it is around 2380.

should I only adjust the vcore and NB voltage? What about PLL? I dont want to exceed 1.5vcore or get my temps over 55c until I know more about the limits on this chip.

Thanks in advance.

Good thread. I am waiting on my mobo to get here to install my 1055t. What's the day code on your cpu?

I've been reading up on o/c these chips and finding the right vcore does seem really confusing because CnQ and turbocore both affect vcore.

I don't have answer to your question, but hopefully someone else does!

 

[Dadofamunky]

MarkFw turned off turbo on his setup. I'd recommend doing that if you haven't already...

 

[richierich1212]

Disable Core Performance (turbo mode). This will enable you to drop vcore, which will help stability. Also disable Cool N' Quiet and C1E.

 

[jthunderloc]

Disabled cool and quiet and turbo boost. Boosted cpu-nb to 1.35. It's a bit confusing as there are 3 diffrent nb controllers. Still adjusting and tuning, currently at 3.85 at 1.4, nb at 2200. Really enjoying this OC, the guides take the challenge out of it.

No idea on the codes, I'm guessing its on the chip, which is in use.

You don't need to boost cpu-nb voltage to 1.35 unless your NB is clocked really high and you're running high memory speeds with tight timings. Since your NB is only at 2.3ish try 1.2v cpu-nb. Put 1.2v for NB.

 

[richierich1212]

Oh, and in the BIOS, it's weird how Gigabyte shows default vcore of 1.475 on some boots, and 1.35v in others (very buggy, I'm not sure if your 890 board does that too). But I told Mark, whenever you're adding vcore, you're adding to 1.35v, since turbo is disabled.

 

[jthunderloc]

You don't need to boost cpu-nb voltage to 1.35 unless your NB is clocked really high and you're running high memory speeds with tight timings. Since your NB is only at 2.3ish try 1.2v cpu-nb. Put 1.2v for NB.

I was running it closer to 2.6, had to dial it back. currently stability testing at 3.85 @ 1.4 vcore. I'll dial back the cpu-nb and see how it runs from there.

[jthunderloc]

I'm getting the hang of this bios, its just weird. When I set the voltage to manual control it sets everything to 'Normal' - which overvolts a lot of things. Checking the vcore it shows 1.35 as +0 and 1.2 for the NB as +0, however it defaults to higher voltage, and everyime I hit the minus key it adds voltage. strange, strange bios.

Stability testing at 1.4vcore and 1.2 NB @ 3.85. I'll give it a 10 minute LinX pass then push on.

[richierich1212]

What RAM do you have? Memory speed / timings / vdimm?

 

[jthunderloc]

Corsair XMS3 DDR3 1600 rated at 9/9/9/24 @ 1.65v. I've got it set to the 5.33 multiplier, and I think the voltage is at 1.5 (or its at 2.25, hard to tell, I'll pull the settings up during next reboot) timings are auto set to 8/8/8/20. I set it to rated specs but that was at the 6.66 multi

BIOS is showing me this
CPU PLL - 2.500v
DRAM Voltage - 1.500v
DDR VTT Voltage - .750v
NB Voltage control - 1.200v
Sideport men volt control - 1.600v
NB/PCIe/PLL - 1.800v
CPU NB VID control - 1.200v
CPU Voltage control - 1.400v
Normal CPU Vcore 1.475 this is grayed out and looks like its for reference, its not adjustable.

RAM is at multi 5.33 @ 1492mhz

[richierich1212]

Could you post up a picture of cpu-z with both main screen / memory timings?

 

[jthunderloc]

Set the ram up correctly, back to rated timings. I'm up to 4ghz, just trying to get stable. Looks like its going to need 1.475vcore, its so very close at 1.45.

Temps in HWMonitor are good, I'm getting 55-57 on the cores, coretemp agrees with them. Little higher then I'd like but I have a better CPU cooler coming in sometime next week (Coolermaster V8)

-Wes

 

[richierich1212]

Since you put the memory back at rated timings, what about vdimm? Back to 1.65v?

Have you tried 13.5 x 300?

 

[jchu14]

is CnQ still on? Core speed at 1148MHz?

 

[jthunderloc]

Yep, back at 1.65.

Checked into hwmonitor a bit more and I'm reading that tmpin1 is CPU and it hit 69 during Linx, I had read that 65 was max safe so I shut it down. I could push higher if my temps were lower. Can I raise nb instead of vcore?

 

[jthunderloc]

Tried 13.5x300, wouldn't even make it in to windows

is CnQ still on? Core speed at 1148MHz?

oops, forgot to disable the windows 7 power saving features. fixed now.

I think I just need more cooling power, heat is whats holding me back now, I can get stable, just not under the 65* temp max. I can get stable at about 70* stress testing, which means I shouldnt hit more then 55 during normal use.

[richierich1212]

Yeah wait until your new cooler arrives to be safe.

 

[richierich1212]

Forgot to tell you to lower the memory divider. You did that after putting in 300HTT, right? (sorry, newbie question, lol)

Got an extra 120mm fan do to some push/pull action on the hyper 212?

Hi Folks,

Can someone help clarify a couple of things? First I keep reading about 2.6 ghz NB. I'm trying to figure out on the settings in the bios, of what sets this. I see there is a list of Ghz speed under the HT link Freq, but thats the only place that I can see that lists stuff out like that. The rest lists as a multiplier Currently I am at 4 ghz, just by raising the multiplier & setting vcore at 1.45v.

By chance should I mess with the NB or only when playing with vcore, mulitiliers are not enough. Another words, while everything seems fine where I'm at, is there something else I can do that will make the speed I'm at even better?

I am posting a screen shot of my bios.

Thanks!!

 

[richierich1212]

Change CPU NorthBridge Frequency. Then change CPU Host Clock Control. Then put PCIE Clock on 100MHz.

 

[richierich1212]

Then change NB voltage to 1.2v

CPU-NB Vid to 1.2v

HT Link Width 16-bit

 

[choliscott]

Ok I'm confused on what to change the NB Freq 2 as it lists a multiplier. I'm assuming that I set the HT link Freq to a certain speed & the Cpu NB freq is the multiplier of the HT Link Freq

I changed the Cpu Host Control to Manual & changed the PCIE clock to 100 mhz
I'm assuming the Northbridge volt control is where the voltage of the NB gets set. However I'm seeing an increase selection, so I'm not sure what its currently set for.
I did set HT Link width to 16 bit
