Ok, another simpleton question, what’s the crack with ram these days?
having just dug out the box for my lag 775 board which had all of my case accessories in I found my original OCZ platinum PC6400 matched 2x1gb 4 4 4 15 sticks which I assume means I’ve OCD black under the desk ATM.
Now, all this new fangled and vegazled ddr 4 stuff doesn’t make must sense, but LTT seems to suggest ram makes 2/10s of no difference to overall system performance so just get a dual channel kit with as much as you need.
So any 16gb matched kit deals about? Should I be worried about speed?

IPad Mini 2, Asus Nexus 2012January 29, 2017 at 8:41 pm #2956It’s all benchmark willy waving really.
It’s so cheap these days I pay more notice of the compatibility list and just get something above the basic that’s on it.
February 5, 2017 at 10:31 pm #3411Build, must always build.
That way if it breaks you have a better understanding of which component needs hitting with a big hammer.
Regarding ram prices its not so cheap… 8 months ago 16gb of vengeance lpx 3000mhx was £60 ish, now its £120 ish.
February 5, 2017 at 11:10 pm #3413I remember when it was £64 for 64mb, so it’s cheap.
February 5, 2017 at 11:17 pm #3414I remember when it was £100 for 4 MB.
That is not a typo.
February 6, 2017 at 5:39 pm #3450well memory choice buggered my bishop order, they ‘no longer stock’ items they still show as stocked on their website so the hunt continues for a cheap 8 gb kit.

That must have been about right, I did spend over £400 on the children’s machine years back, though the shock of finding the old pack a little while ago made me forget just how much there was. It might have been a whole rip roaring 16MB.
Times change and sometime for the better, these days getting memory from Kingston, or Crucial is much easier on the wallet.

hardware in the case, a little sad to say goodbye to a 10 year asus friendship with that board. But such is life, and the 750ti is asus anyway.

February 22, 2017 at 8:59 pm #4281by March the 3rd well find out it was just BS. Probably.

According to Ars, they have it all ready for benchmarks to be released on release date.
I hope it’s not BS as it could allow me to construct some nice fire modelling machines on the cheap! :good:

Not knocking your idea, but wouldn’t a Beowulf cluster of Pi Zeroes be better for Monte Carlo simulation work? Agree that CUDA etc give you ready access to parallel operations but there are cases where individual processors MAY be better. The example below is for disease, but an ‘explosive’ fire could result in similar propagation characteristics (i.e. one source rapidly becoming multi-source at geographically disparate locations.).
…. However for creating a cluster running some thing like “condor” Which can be used for things like Disease out break modelling, where you are running the same mathematical model millions of times with varible starting points. (size of out break, wind direction, how infectious the disease is etc.. ) so thing like the Pi would be ideal. as you are general looking for a full blown CPU that can run standard code.http://research.cs.wisc.edu/condor/

Forumite Points: 0I’d rather get a Ryzen with 16 threads than 16 Pi Zeroes to crunch numbers?
I’m excited for it. I have no intention of upgrading my system for now, but competition is always good. If we are to believe the few benches that are out, AMD is on to a winner. Especially as all these parts are 95W TDP. If Intel came out with something, AMD can still up the ante to 135W TDP if they needed.
February 24, 2017 at 12:19 am #4410Higher wattage is so yesterday. They will win no friends by doing that.
Quite honestly I couldn’t give a flying flip about the high end stuff, I want to see the CPU that takes on the Kaby Lake Pentium G46xx series or even the Sky Lake G44xx series. Having just built a G4400 / 4GB / 240GB SSD machine the damn thing flies for “every day” tasks.
February 24, 2017 at 4:24 am #4411Well, the pre-order prices are up. The Ryzen 7 1700 still has the full eight cores (sixteen threads), the full amount of cache (4 MB L2 and 16 MB L3), and costs just $329. And the TDP is 65 W. It’s a 3 GHz part, with a 3.7 GHz boost. The top model, the 1800X, runs at 3.6 GHz, with a boost up to 4 GHz, for $499. The TDP is 95 W. (Put £ instead of $ in front of the numbers and you won’t be far adrift.)
If the figures even remotely stack up, the 1700 looks like a winner to me. How well are the boards priced?

It’s CFD modelling, not Monte Carlo simulations. We’re looking at smoke flow around a building normally (the software is here). My current firm do have a Monte Carlo simulation tool but it isn’t used much (I don’t think they market it enough).
The modelling software doesn’t make use of CUDA either (a German research team tried to get the code running on CUDA but was unable to – lots of data I/O I believe the issue was which slows it down to make it not worth the bother).

February 24, 2017 at 3:50 pm #4460Just found this old article “Official AMD Bulldozer (FX-Zambezi) Benchmark Slides Leaked, Performance and Pricing Detailed”.
Dated 24/9/2011 and Bulldozer was released on 12th October, so timescales not too dissimilar to where we are with Ryzen today.
“When compared to Intel’s Core i5 Processor, The Bulldozer CPU which falls around the same retail price tag (<245$) would provide 4 More Cores, 8 Times more L2 Cache, Faster Frequency, Advanced ISA’s, Full x16 Bandwidth in CrossfireX mode GPU’s and fully unlocked Processors. The graph also compares total PC cost of an FX-8150 Processor with the Intel’s Core i7 980X CPU. The Intel solution would cost a total of 2120$ while AMD’s Bulldozer in comparison would cost 1286$ and the performance difference in between both solutions in barely noticeable as shown in the benchmarks below:”
“Most of AMD’s Benchmarks consist of games where Bulldozer definitely outperforms the Intel counterparts. At a resolution of 1080P, Bulldozer easily dominates the Intel Core i7 980X which costs twice as much as FX-8150 and the CPU is also 10-20FPS faster than the previous gen Phenom II X6 Chip in most benchmarks.”
“Bulldozer also shows 10-30% improvement in CrossfireX enabled rigs against the Intel CPU’s. That’s mainly because of 4 Cores bottlenecking the GPU’s full potential which the extra 4 Cores of AMD will unleash. In CPU intensive apps, Bulldozer falls between the i5 2500K and i7 2600K Processors, Only in a few benchmarks it outreaches the 2600K but in most situations it’ll lack behind. The new AVX/AFX Instruction set also allows an 3x improvement in hardware encryption over Phenom Processors. You can see more on Bulldozer below:”
We all now know what a load of bollocks this is. It’s why I will not believe anything about Ryzen until it’s in the hands of third parties.
February 24, 2017 at 6:28 pm #4469I truly believe they’ve pulled something special out of the bag this time.
February 24, 2017 at 6:29 pm #4470I really hope you’re right.
