Phenom X6 1090t weird problem

[Gux]

Every once in a while when a start my computer, the CPU is not acting normal. Right now as I type this, the max cpu speed is 1.6Ghz, the core voltage is 1.472 and the temperature are in 50c+ in idle. CPU usage is less than 5%. Also in CPU ID it no longer says "Phenom II X6 1090t" in the specification window but "AMD Engineering Sample (ES)"

When it runs normal, it runs at 3.2Ghz the core voltage is 1.400 and the idle temps are around 35c. It also says "Phenom II X6 1090t" in CPU ID. I have cool and quiet turned on so I don't know if this is causing this problem.

One more thing, when I first bought this computer the cpu voltage was 1.55v at load so I manually set it to 1.400 because I heard that anything over 1.45 is too much. I am using Gigabyte GA-880GM-UD2H motherboard and stock cooling fan. The motherboard has got F7 bios which is one of the latest versions so I don't think that's the problem.

Any ideas why my CPU is acting strange? I am baffled why the cpu clock speed is at max at 1.6Ghz even if I am ruining prime95 and stressing all cores 100% and why my temps are so high in idle? Usually when the CPU runs fine I get 50c when the CPU is at load at 3.2Ghz.

Thx for any help

Did you build the PC yourself or buy it ready built?

Aside from the temperatures being a bit worrying, can you get a CPUz screenshot when it next misbehaves.

Dunno - maybe you've got a 12 core Opteron with half the cores locked or something*



* just to be clear, I haven't heard of this happening.

Just restarted the comp, everything is in order now except my core voltage which is at 1.232v when I run prime95 with all cores 100% at 3.2Ghz. This is strange since before the core volts were 1.400, I set them my self in bios...

The temps are back to where they were before 35c idle and load 50c. The cpu speed is at 3.2Ghz which is normal.

I build this computer myself back in late November. It was working fine until last week. I haven't changed anything settings wise for months now. The only thing I changed was the core voltage which was at 1.55 when I first started the computer after I finished building it.

Personally i would reset the bios back to the default and see what happens from there. You shouldnt have needed to adjust the cpu core volt unless it was OCed.

If its anything like the Gigabyte ive just setup the cpu volt in the BIOS is more of +- .1v etc rather than setting to 1.55v directly. If CnQ enabled i found that the Max Cpu Volt would change on boot.

I instead used Amd Overdrive to set the Cpu Volt, that way it allowed me to set the Max volt as oppesed to the Vid.

try resetting the BIOS. If that doesn't work get AMD overdrive or CPU-Z and check the settings and if they're still the same try to set them to what they are supposed to be in AMD overdrive which they should be at stock which would be 3.2Ghz for the 1090T. Other than that all i could think of would be something could be faulty.

sounds quite hot as mine idles at 24'C with stock cooler and 18 now with the zalman cooler

Clear the CMOS using the 'remove the battery' method - i.e. Remove the battery after powering down - press the power button a couple of times to remove any charge in the PSU. Reset CMOS and leave alone for 10 to 15 minutes.

Wierd that its coming up as an Engineering sample!. 1.4v is way too high - that overclocking territory!.

Mine runs 1.28v stock idle and under load if I recall it used to go upto about 1.32v max!

Right now everything seems to be ruining fine except occasional bluescreen when I am playing GTA4. I don't think that's the cpu problem since the error message seems to say something about video ram error???

Set the core volt to normal now and its running at 1.376v. Might try and undervolt the CPU since temperatures are getting near to 60 when playing games.

What are long term effect of ruining CPU at stock at 1.280v? The computer is stable at that voltage so is it safe for long term use (3+ years)?

Thx for the help guys

Only risk of undervolting CPU is instability. No long term damage likely.

+1. CPU Damage would usually come from overvolting. If the cpu isn't getting enough volts (undervolted) then it would just either slow down or just not boot / reset. You would know if it didnt have enough power

Not quite as straighforward as that. Undervolting is a bit like overclocking in reverse. You'll find that with not quite enough voltage you'll get errors in stability tests and games, BSODs, freezes, hangs etc.

It doesn't throttle (slow down) like it would if overheating.
