1090T Voltage Question...

post #1 of 23
Thread Starter 
I think my 1090T volts is at automatic. I downloaded the program called AMD Overdrive and my Voltage keeps changing from 1.23 to 132v.
How can I get this stable @ 3.2?

1090T CPU
m5a99x MOBO
2x4gb HyperX Kingston 1600mhz RAM

And how come my HyperX shows at 800frequency?

Any help would be appreciated.

At stock your voltage will change along with the frequency of the cpu and whether or not turbo is active.

It's normal. Also, be careful with AMD Overdrive, it's kind of wrong sometimes. Especially regarding voltage.

Use CPU-Z instead.

oh ok, good to know. I dont know anything about these voltage and what not at all.
i'm using amd overdrive for temp watch unless you have a better program?
and any idea why my ram shows at 800freq?

I use this with overdrive as well. It is more precise than overdrive.

Edit: Both are used only for monitoring.

have you manually disabled cnq and set your ram timings by hand?

( also don't use overdrive to do any overclocking, do it all by hand in the bios )

As the other posters said, HW Monitor is a good way to watch your temps. With x6 chips like ours, ( I also have a system with the 1090t ) you have to be watching both the core temp and the socket temp which you can with HW Monitor. There are a lot of good threads on here for specific overclocking advice with Thuban CPU's, search for them and most of your questions should be answered, if not then post back here.

The reason AMD overdrive shows your memory speed as 800 Mhz is because that is the speed it is running at. 800 Mhz x DDR3 ( Double Data Rate version 3 ) = 1600 Mhz. So if you bought 2000 Mhz ram, it would be reported as 1000 Mhz DDR3.

You would be better off not using the AMD Overdrive. It can have a tendency not to represent correct core temps. Even AMD recommends using CoreTemp to monitor your 1090T. I use that and it works really well. Also, if you decide to overclock I would do it straight from the BIOS. Don't use the software to do the job I do not think it does as well.

OP, See my guide for more information concerning temps.

Ignore socket temps "CPU Temp", they are not accurate under load.
You only need to be concerned with "Core Temp" under load.

I respectfully disagree.

Core temp is only accurate at 45c. Above and below that AMD have stated that the core temp readings are not totally accurate. Therefore, it would seem like a good idea to watch both the socket and the core temp.

I have observed up to a 10c reduction in socket temp by placing a fan pointing at the back of the socket. That did help to lower the core temps as well so it would seem they are indeed linked.

EDIT: I read your guide and I feel there is no conflict with what I stated. What are your thoughts on the lowering of the socket temps in relation to lower core temps?

I just saw a system today where the socket / "CPU Temp" was reading 15-20C higher than the actual temp and from idle to that point it was still between 10-15C off, so it's just a variable from system to system and not a good indicator of anything. I've also seen systems where "CPU Temp" read higher at idle than it did at load, so again the TYP 7-10C rule doesn't always hold true.

So "CPU Temp" will always be off, by how much depends on the mobo and the sensor as well as other factors, where "Core Temp" does exactly what it was designed to do - which is report correct load and peak temps so that you can stay under the recommended limit for your chip.

As I mention in my guide, idle temps for both values will be inaccurate. Which IMO, doesn't matter, because do I really care what my idle temps are if I know that under load it's only 38C? And btw, just because "Core Temp" equalizes at 45C, doesn't mean it's completely inaccurate up to that point. As long as the CPU is under load, the equation works to be within 5C, then past 45C it's within 1-2C. The only flaw is that it can't do straight idle temps, because the equation factors certain aspects of load and it's effect on the chip itself pertaining to heat.
