No

. I can add my second Thuban, but I need more free time to test it completely.

Thanks...figured out a way to get things under control. The Asus turbo V software really helped.

I run 1x360 BIX and 1x120 XSPC all on Sythe GT 1850's. But it obviously is still not enough to hold 1.5v plus. The below run topped out at around 52 degrees on the core. Whats the safe temp for AMD these days?? My ambients are around 23-25 degrees.

Here's where I am . 3 hours prime 4.06 ghz. Set to 1.385v in bios. With load line went to 1.41v in CPUZ. CPU NB at 2.7 and ram at 1800 CL8

Next up 4.2 Ghz.

Without load line, the board tends to under volt a lot and that kills stability.

Oh, I see. In the future make sure to mention that it's a new entry / chip as otherwise I have no way to know. The only reason I asked in this particular case is because the clocks were lower.

I'll hold off until you're ready if you still need some time with it first.

Looking good!

Noctua NH-D14 cooling, 25c ambients, censor on different room so here might be even warmer cause cpu warms a LOT!
1.475 for CPU from bios.. actual stress-voltage on cpu-z.

And here is the final result. Ambient temp started falling after i just opened my rooms door, so the air could chance!

No cold air or anything.

very nice Asmola!

looking good

if you click the link in my sig it shows voltages i needed for clocks ranging from 3.2ghz to 4.3ghz (which will obviously be different than yours) but more importantly it shows my temps at said voltages which might give you some insight. my water is also listed in my sig, both rads using 100+ cfm fans for those tests though

To a system with less cpu-nb voltage is not constant.
voltage is much that I use; will destroy the IMC ?

Hello, a question:

Right now I test my new 1090T, it is currently stable at 4GHz with 1.44 v, and wanted to know, how much is the maximum voltage recommended for use 24 / 7.
I've been looking for, and some say it is 1.50 v, one that is 155V, but I clarified.

Greetings and Merry Christmas to all!

Is NB multi locked upwards for Phenom 1055/1075?

**FlanK3r** · 12-30-2010, 02:08 AM

NB multiplier is locked only +upwards. U can chage it down (clocked this CPU with busspeed)

**saint19** · 12-30-2010, 05:10 AM

Hi guys.

Currently I have a Gigabyte 890FXA-UD5 with a 1090T @ 3.8GHz, NB@3000 and HT@2000MHz, the voltage are: 1.325V for CPU, 1.150 for NB and 1.375 for CPU/NB. Some people has tell me that run the CPU/NB with a voltage above of CPU voltage is dangerous, Is that true?.

**Asmola** · 12-30-2010, 05:18 AM

Then how did this happen??? It's obviously a 15X multiplier on the cpuNB.

I think FlanK3r meant those non BE-processors, which have locked multi.

Doh!

This 1100T seems to like overclocking better than my 1090T did. Don't read too much into NB or memory clocks as they're relaxed for CPU clock testing. I was stable at 3GHz NB for instance at 3.8 GHz, but 4.0 GHz was a wash at any voltage. Relaxed NB and 4GHz was doable at stock turbo voltage (1.45V)--maybe even less (I didn't check).

**Particle** · 01-01-2011, 09:27 AM

Charts are up to date.

It looks like I'm first to the punch with an 1100T--what gives?

Updated.

**Particle** · 01-03-2011, 04:36 PM

Running up against some sort of hard wall. I can do 4030 at 1.45V and pass 10+ hours of OCCT, but 4100 is a bust at any voltage, NB clock, or memory clock within seconds to minutes.

**cdawall** · 01-03-2011, 04:38 PM

temps are too high

**Particle** · 01-03-2011, 06:40 PM

Mid-50s? Nah, that's pretty comfortable. We're talking about +70 MHz here.

A load core temp of 55 or so is typically where Phenom II's, including the X6, start getting unstable.

Sure, you can run 60-65 (maybe) at stock speeds but who runs that slow?!?

**Particle** · 01-03-2011, 07:09 PM

Frick'n heck. I'm already using a Tuniq Tower 120 Extreme with two Scythe S-FLEX G fans.

**QuietIce** · 01-03-2011, 07:41 PM

Do you have 80+ CFM of exhaust fan(s) on the case to go with that?
