Cherry pick the combination with the highest bus speed.
Use that return policy.

Newegg and Amazon's CPU return policy would not permit this.

As others have said, it's nothing to worry about. My bus speed on my 990FX motherboard is 200.67 to 201.55 depending on what's going on. The CPU is still running at a 4.7Ghz clock speed, but it's still a little off because the bus isn't perfect. No big deal.

Well sometimes people have a question... and they just want an answer or explanation for it... that's all smile.gif --> so they can give it a place in their mind wink.gif

Anyway, Iv'e seen mine ALWAYS @ 100.00

Lucky the Asus board I have can keep my personal flagship processor right on 4.2GHz, if it was anything less than it would be 4.1xxGHz, sorry cant have it like that. It does fluctuate slightly on the core speed a tiny amount about .01 up and down, but generally stays right on .00, in any case all good. The Bus Speed is reported on 100.00 at all times.

There are people out there that want to see on CPUz that the clock speed it right on (or in a super tiny faction of it), even if really in the background it is not perfect and monitoring software maybe report it.


That's a pretty stupid form of OCD though. If CPU-Z would round to .0 then their (and your) standards would suddenly be lower. After all its megahertz. In reality 100,0 MHz is 1 000 XXX , why would you care about the 4th digit being exactly 0 while not care about the lower significant digits?

What about the speculation that if you BCLK is not exactly on 100 then you are unstable, even if you overclock but 1MHz. Would the same be true is under-clocked by 1MHz. I have read that if the BCLK is not the right on 100MHz than the attached devices internal clocks are still running at 100MHz and cause a delay latency with the discrepancy of the clock speed. Don't know if this is true of not, but I don't bother to overclock by an extra 3MHz on the BCLK, just in case this might be true.

This is wrong for multiple reasons. First is that again its MHz so you don't even see the exact number in CPU-Z. Secondly, attached devices might not even run at 100 MHz, my GPU runs at 975 MHz, not even a multiple of 100, and your RAM is fed by the same base clock as the CPU so those have same clocks. And third, since clocks never match anyway it's build in, in electronics to deal with it.

Lol, the pcie express bus is 100MHz, and linked directly to the bclock on the platform in question.

this just wanted to know everything was ok
spend 1.4k on a pc dont want an issues.

I am going to call you on that one. Have a good look at your pictures. The version of CPU-Z that you are using only reports the BCLK to 1 decimal place. Can you try your test again with a different version of CPU-Z that reports the BCLK to 2 decimal places.

4600.6 / 46 = 100.013 MHz

1599.6 / 16 = 99.975 MHz

If your BCLK was being calculated 100% accurately, you wouldn't be seeing this variation. Bring your computer to the lab and throw it on an oscilloscope and the BCLK will be steady to at least 3 decimal places.

1.68


odd...

so my first post was with 1.67 and i got 99.98
but with 1.67 rog version asusfreak got 100 on the dot and with 1.68 rog version i got 100 on the dot and hwinfo also got 100.
but with stock cpu-z version 1.69 i get 99.98 again.
i think it may be something in the diffrent version that make the bus speed come out different.

so the rog version cant read the bus speed right

whgat.

I guess sarcasm just doesn't translate well over the webs.
I mean, if I couldn't get 100, I would just give up and run stock.
