New Computer

[chevyordeath]

Last night I put together my new pc (see sig for specs) and everything went well. Booted up just fine, installed Vista 64 bit with no problems. It is still running great right now.

I've downloaded all my 64bit drivers, I've got the latest chipset drivers from DFI, latest Bios.. the works. But for some reason when I check CPU-Z it is giving me odd readings.

It is saying my core speed is 1250 MHz.. A bus speed of 200MHz with a multiplier of x6.25. There is no way in hell this can be right. My memory is the same way. It sees all my memory correctly, the timings are right (I had to manually change the timings) but correct me off I am wrong but it says my DDR2800 memory is running at 400MHz, shouldn't it be running at 800MHz?

I've been playing around in the bios but everything looks right. I will admit I am still a bit of a novice when it comes to bios, and this is my first expirence with a DFI board, I have used only Gigabyte in the past.

So I am wondering, is it possible that CPU-Z is just giving me bad readings? Or is it more likely that I am missing a setting in the bios?

Thanks for reading, this is really starting to give me a headache.

Dual Data Rate, that will say 400, its only telling you one side of the ram.

same with your cpu, 4 x 1.25

[chevyordeath]

So everything is correct? The ram makes sense.. but the cpu, 4 x 1.25 is 5GHz. My processor is a 2.5GHz processor shouldn't it be 4 x 2.5?

give us a cpuz screenshot of the first tab

Try running your rig under Orthos, and look at the CPU-Z screen. If it goes up to what it should be, go into your BIOS and turn off Speedstepping or whatever it's called on AMD, especially if you're going to be overclocking your rig at all.

I am starting to wonder if it clocks itself up or down as needed based on load? Is this possible? I have been keeping CPU-Z minimzed in the task bar and every now and again it will jump to 2500MHz but then it will go right back down to 1250MHz... Curious.

Give it some load and the core speed will go to 2.5GHz.

Not to sure about the HT link...I'm sure its meant to be faster then that unless it goes up with load too?

[chevyordeath]

Bingo. Downloaded Prime95 64bit, as soon as I started the torture test CPU-Z reported everything at normal, Core speed jumped to 2.5GHz the multiplier went from 6.25 to 12 and voltage went up to 1.28. Test still running now, cpu usage at 100% and I can still navigate windows with ease. Everything looks good.

edit:

HT Link still at 2000MHz. I think that might be the default speed.

[chevyordeath]

Hmm.. I checked the specs on my processor, and you are right, Peter. The HT link speed should be 4000MHz.. Maybe I should take another trip to the bios and see if I can't change it.

[chevyordeath]

Nope, 4000MHz is incorrect. I have no damn idea where they got that number at.

According to this articale here; http://www.thetechrepository.com/showthread.php?t=258

The top HT Link speed is 2600MHz.

Well. Problem solved I think. Thanks for all the help guys, I was worried for a bit there.

Did you even read my post? -_-

Seriously. I told you that like 5 posts up.

[chevyordeath]

I did. But I didn't see it until after I posted right after you. that's what gave me the idea to run prime95. Thank you.
