Can't reach stock speeds on AMD Phenom ii x6 1045t

[MewsicLovr]

I recently purchased the CPU in the thread title. It seemed to work great when I first fired it up, but now it runs like a dog (this is in the timespan of ONE day!). I ran CPU-Z to verify my suspicions and it is indeed running ridiculously slow. I'm positive it didn't start this way, but I don't know what I did to trigger this; certainly nothing on purpose. Everything I've done below so far is to simply try to get it running back to the stock speed (2.7 ghz).

I have attempted:

- manually modifying the multiplier to 13, keeping FSB to 200 (no effect)
- modifying the FSB to 250 (this DOES create an improvement but the multiplier stays at 4x so it's still very slow)
- Just for grins, I modified the FSB to 400, but unsurprisingly this caused the system to not boot.
- leaving everything totally on Auto. (I get 800mhz speed).

My mb is an Asus M4A79XTD EVO.

If it helps, here is the Memory tab on CPU-z as well. My memory is also rated much higher than what it's running on, so I don't understand wtf is going on.

What am I doing wrong? I'd appreciate any help. Thanks in advance!

Did you upgrade to the latest BIOS? Have you checked the CPU under load? Maybe your Cool N Quiet is messing up or something.

Are you actually doing anything with the system? Because if you aren't, its just clocking down to save power.
Fire up an app like prime95 and see if it clocks up.

Firstly... Clocking down to 800mhz is perfectly normal when a processor is idle.
Download and run wPrime, set it to 3 cores and watch it hit 2.7ghz + Occasional spouts of turbo.

You can disable this by turning off AMD Cool 'N Quiet in the bios, which is similar to Intel Speed Step.

Secondly... Your motherboard may be setting the memory speed automatically, so just go into the BIOS and set it's correct speed; a few systems I have had to do this with.

Thirdly... You should be able to hit around 3.3 -3.4ghz on stock voltages on that 1045T which should be fine with a stock Phenom 2 cooler that has the heat pipes. (Which the 1045T doesn't come with.)

Lastly... If you do intend to overclock the 1045T... Remember that you need to add 13'C due to a temperature bug in the Thubans with applications like Core Temp.

On every system I've tested lately, CnQ does not work like it should. It constantly clocks lower even when it should be at max multi. Really annoying. I had to install visual studio 2010 on that A4-3400 I reviewed a few months back. When the load was around 60% it was still clocking all the way down to around 1200MHz consistently. At that load it should have been at max multi. I just disabled CnQ.

Actually, that's great. I'm pretty confident the % load is for whatever speed the CPU is currently running at, not its theoretical max. Therefore, if the install is only using 60% of 1.2ghz, boosting will only waste power.

You were likely IO limited, installing VS2K10...

CnQ used to be broken... on the original Phenom. PhII and later Stars-based CPUs have no problem. That being said, if something bumped my PhII 1055t to 60% usage, it probably WOULD go to stock multi. Which says to me that CnQ has gotten BETTER, not worse.

I don't seem to have a "max processor state" option. I did have "System cooling policy", which had options "Active" and "Passive" (active was selected). I think I turned off some power saving options in the bios so that may be why.

To others suggesting it's being throttled for power savings:

I downloaded and ran Prime for a few minutes, but the core speed did not change from 800mhz except for tiny variations in tenths of mhz. Prime was definitely working.

I *think* cool and quiet is disabled in bios, that was one of the things I attempted during troubleshooting. I'm not aware of any other software I'm running that might be throttling, but I'm looking (computer slow.......). I certainly don't want it throttled because I use my comp a lot and I'm usually very processor intensive, so disabling any throttling is fine with me.

I'd love to overclock, but let's get to stock first. :\

I'll also update the bios to see if that works.

Updating the bios seemed to do the trick! System started up recognizing the 2.7 ghz. Prime is chugging like a champ. System is noticeably MUCH faster.

but...now I'm getting some strange numbers. Is this normal? I'm running with the auto-overclock profile of +10%. (btw - I have a thermaltake fan on there [somewhat older] - variable speed that I control, has a pretty large heatsink - I would imagine it could handle this)

Thanks so much for your input guys!

Most likely this ^ or that your mobo Bios is not phenom II'ing like it should.

New World Record! Nice

 

[MewsicLovr]

New World Record! Nice

Yeah... so, obv some kind of software error then?

 

[MewsicLovr]

So yeah I restarted the comp and tweaked a few more settings in bios. Now CPUz reports a more normal speed of 2.97 ghz.

Thanks guys!

Too bad that 10 GHz Thuban isn't for real. I'd like to show THAT to all of the Intel fanboys!
