Corsair 178300 Vengeance LPX 16 GB (2 x 8 GB) DDR4 3200 MHz C16 XMP 2.0 High Performance Desktop Memory Kit for AMD Ryzen, Black

Product Information

I don't know if it matters about BIOS version or motherboard manufacturer but I was planning on considering a Ryzen build.

If your problem is you can't get your XMP kit to run at XMP frequency then start with JEDEC speeds first (2133 to 2666) with XMP DRAM voltage. So, I installed the latest BIOS (dont know if that mattered, but at least the beta BIOS is not broken). The thing is, I think the B version I have is Samsung though it doesn't specify B die. The Manufacturer says Samsung and it just says 8gb/1 die but I'm assuming that's a Samsung B Die. said:What was the system build used for the testing? Is it me or it's missing from the article?it seems that part of the article got "cleaned" :) I used the import feature from Thaiphoon because I noticed that even though I put in the correct specifications in all the main fields like rank, number of modules, frequency etc the timings still changed when I used the imported file in DRAM calculator. I left Samsung b-die instead of Samsung OEM, as you suggested, because that would give me invalid numbers. Then I heard about what you said about tRFC and I set the alternative setting (432) as well as the tWRRD (3).My online research has found till now that everyone with hynix chip (RAM version 5.39) have the Intel optimized(B) module while those who owns the samsung b-die (RAM version 4.31) have the AMD Optimized(Z) module. If you want to benchmark RAM, it seems like you understand that you need benchmarks that are RAM constrained and compression is part of it, though that's largely CPU bound not RAM bound. In terms of WinRAR specifically, this benchmark offers nothing because your resolution is so poor you can only separate dual cores from quad cores from hex cores, you can't distinguish hex cores with DDR4-2400 from hex cores with DDR4-3200. On top of that, WinRAR is more dependent on the disk so using an M.2 PCIe 3.0 x4 drive should be distinguishable from a SATA-III SSD, is distinguishable from a HDD. You could make the WinRAR benchmark more meaningful by using a bigger data set -- if 1.3GB takes 30 seconds then 15GB should take about 346 seconds and now you can resolve to within 1/346 = 0.29%. Well below what anyone really cares about. For RAM constrained applications, look into more scientific applications. Also worthwhile would be X99 in dual channel vs X99 in quad channel. Now, I'm not sure if I should go for the same model I have and risk getting a Hynix version or go for the Z which is always B die.

As you step up in frequency and you can't seem to get DRAM Calculator values to work you can revert to what did work (from the previous step) starting with ProcODT, RTT, and CAD values.

Finance is only available to permanent UK residents aged >18, subject to status, terms and conditions apply. Assuming your chips are the same kind of Samsung as mine (based on version) it may exhibit similar properties to mine. The DDR4 form factor is optimized for the latest AMD and Intel DDR4 motherboards and offers higher frequencies, greater bandwidth, and lower power consumption than DDR3 modules. Vengeance LPX DDR4 modules are compatibility-tested across AMD and Intel DDR4 motherboards for reliably fast performance.
