Hrm..

So my sticks posts at 3466 @ C15 @ 1.4V but definitely not stable. I don't think mine will do 3400+ @ C14 like JPM's frown.gif

3200 is the best ratio still for 24/7

Is this with your 5960X?

Which strap?

I'd appreciate if you didn't edit my posts, considering you've since made it now incorrect. It applies to all CPU on the platform.

LOL Why is that incorrect? your statement was just a opinion. What make's 3200Mhz the best ratio? because you can run it on 100 strap? or most cpu's should be able to handle 3200Mhz ? Or because you said so?

Because if looking simply beyond recognition for screenshots, when considering the voltage and sub timing relationship with the frequency, 3200 is the best ratio. Beyond this the scaling for certain predefined settings scale up quite a bit.

Obviously you might not realise this yourself, as you don't own a BWE CPU.

Okay.

I'd agree given more BW-E samples.

variance seems a bit high!

Any link for the Asrock Configurator?
TimingConfiguratorv4.0.3.zip 2879k .zip file
TimingConfiguratorv3.0.5.zip 2619k .zip file
one of these will work with your 5960X/R5E.

Is that with your 6950X? If yes, 3400 should be doable. (2T, mode 3). Warning: Spoiler! (Click to show)




For HWE.. 3200 is def the least resistance. Started as and has held up as the strongest memory ratio on this platform IMO. 6950x/R5E(10) ... 3400 seems best with the current crop of sticks. 3466 is doable, but gained nothing in performance that I could tell. redface.gif

That depends on your usage... Comparing 6950x to dual 2690v4 core-for-core, I'm finding my applications reflect aida64's memory throughput quite directly.

That is to say, even constrained to 8 cores, a generally decently scaling, but real-world (i.e. cores do communicate, share memory, synchronize, etc...) application (that I cannot name) is showing me that this application is primarily constrained by memory throughput, but not just on a given bank, but all banks combined.

The 2xXeonx2400DDR4 setup has an overall memory throughput of 115-125GB/s (over both CPUs) according to Aida64.

Constrained to 8 cores the 3.2GHz Xeonx2400DDR4 is running the same application in the same time or better doing the same work as the 4.4GHzx3000DDR4. At lower clock speeds, the logical explanation for this is that parallel functionality is able to move data through 8 channels of memory better than 4 (not surprisingly) and correspondingly the faster 6950x cores must be spending more time waiting for data.

So, its not all muscle-shirts and hair-gel. wink.gif
