lol I know that. I'm just saying everyone else is stuck at 4.5ghz or less

most reviews are on the asrock boards.

For if the person wonders how memory speed is calculated well it is kind of like they do with the gpu to keep things simple we are going to neglect the bus width for now:
DDR(double data rate meaning the the bus multi is 2) is the type of ram the subfix is a clock multiplier(times bus multi but that 2 and pretty irrelevant) which goes like 2, 4, 8, 16(DDR4) aka doubles just like it is with gpu memory where is goes 1, 2, 4(GDDR5) this is also the reason why some subvendors list gpu memory clock as "effective speed" which is clock times multiplier.
Multiplying clock speed in MHz(which of course stand for Mega s^-1 or Mega per second(Million cycles per second)) with the multiplier and multiplying that with the bus width will give give the bandwidth in Mbit/s

Par example (both on a 64 bit bus which is common for dual channel):
DDR3 400MHz * 8 * 64 = 204800 Mbit/s = 25600MB/s
DDR4 400MHz * 16 * 64 = 409600 Mbit/s = 51200MB/s[/quote]

O ok I understand. I obviously did not realize that ddr4 would have twice as much bandwidth. redface.gif So ddr3 4266 would equal ddr4 2133? Is that correct?

So pathetic, another lack luster product. It seems that as long as amd is stuck with this bulldozer arch it will not advance anywhere.

Here's a video of Macci OCing Kaveri:



the first 30s is in german but after that it's in english (because we finns are bad at german tongue.gif )

I thing that we need to wait a little... Wait for Mantle and wait for KAVERI drivers.. if we remember how phenoms destroyed piledrivers - where are they now?
In BF4 cant even comper Clock per clock. It is all about CPU optimization same as GPU...

Not really a lack luster product, if they could reduce the top end product's price by 30%, it'll great value for money.

Uhm Anand has AMD's slides of the 7850K in hybrid CF with a 240 which might be interesting for you?

FAIL.
If you take a Haswell-based Pentium G3220 ($69) and R7 240 ($59) this might be true, but if you look at the cheapest Haswell-based quad-core CPU (i5-4440 priced @ $194) and then add the cost of a R7 240, this might not look as good and you'll realize, you're getting a package that performs about same but at double the cost. Not to forget, with the APU, you've the ability to add a R7 series discrete GPU in Crossfire as well. thumb.gif

What I can see in this thread that a lot of people that are negative/pessimistic about Kaveri are just jumping to conclusions and drawing straws like they are desperate rather than to think thoroughly about the Kaveri, benchmarks, drivers and other factors/variables...

There are currently no native drivers for Kaveri's iGPU's nor even for R# series d/mGPU's thus applications may not use hardware of it properly, Kaveri has Steamroller cores which is different than Bulldozer/Piledriver is notable ways thus software that has optimizations for these two generations most likely won't use advantages of Steamroller cores. Same thing happened with Bulldozer/Piledriver when it launched, there wasn't software that properly used its resources/traits/virtues ultil couple of months later.

Another notable factor is that some FM2+ motherboards have outdated BIOS which could hamper utilization of hardware compared to up to date bios that is available. New hardware gets release and software gets updates/refreshes as time passes that will implement code that will improve utilization of then relatively new hardware.

People that are jumping to conclusions are failures and they likely do the same in real life and no wonder that it most likely back fires to them a lot.

Could the board be the answer...hhhhmm
It is a factor of board and power stability and the filtering of that then you have the processor being a good or a bad clocker relative to the easy achievable clocks finally we have the skill which is by far the biggest factor and a lot of reviewers are just mainstream technology nuts and don't actually have a great deal of experience with OCing.
Alatar now you've seen 5GHz will you attempt 8GHz+ on LN2? thumb.gif
