Low performance for my PCIe SSD Intel 900P

cx5 wrote: {answer for 1}As short as you can get by for best performance. {answer for 2}M2adaptor+short_riser should be slightly tiny better than PCIe2 but not much, nearly equivalent. Only truly better than PCIe3. The whole point of using M2adaptor is to convert PCIe2 or PCIe3 8xlanes into two M.2 sockets get full speed Gen3. ************** You know sometimes in games where there is a split second pauses, like jerking temporarily, usually after completing a zone and moving into next zone, usually loads new assets, even Optane900p in PCIe3 suffers, only at PCIe2 or M2adaptor nearly no jerking. I've been testing many configurations, currently Optane900p in M2adaptor runing OS and primary game launcher like steam, ubisoft, then SN770 1TB in PCIe3 using adaptor card, this gives lest jerking vs. Optane900p in PCIe3 and SN770 in M.2socket1. Next try will be to move GPU to PCIe3 then SN770 to PCIe2.

Wow, thank you again! :-)

ok, so a good option is just PCIe2 as well, because the GPU is fine at PCIe3.

Wow, that SN770 seems to be a beast... seems like being much easier just grabbing one and putting it on the M2_1 :-p or one of the newer SN8xxx. It is more money, from 40 to 130 or 180?? but it brings +1 or +2TB as well... space is always needed :-p hmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

hmmm, I am looking and, while it sais in some places that the Samsung ssds are faster in random reads, other places (including a reddid thread) tell that it is the intel.

So I am very curious about that testing of you :-)

And about, all the lanes going down the motherboard, so being farther away and so with higher latencies... is something that new tech mitigates somehow?

The 1st link is OK good buy.

The 2nd link is too long, will clash with ram for space, can't clear the ram height. Must get just PCIe4x length to clear ram.

I think I will purchase this:

Sorry my bad English & grammar.

I will try! I think I had already the XMP profile but it seems it is not working.

TY! I will try all those things!!!!!!

Now that I see your ram is G. Skill F4-3200C14-8GFX and your CPU is 1700, then the answer is NO, because they are perfect match and you have 32GB which is too much already.

My current Zen2 3800x max out at 3733MT/s=1866Mhz. It again did not achieve other users success of 3800MT/s=1900Mhz, again I said, because many other zen1 uses achieved 3200MT/s or more but my 1700x only got 3133MT/s.

Anyway the sweat spot for zen2 is 3600MT/s, but because I want to use M.2riser_+_shortHEIGHT extention, hence am running my corsair limited to 3333MT/s with 3800x.

I seriously think if you get zen2 or zen3, your existing ram 3200MT/s can be easily overclocked to 3466MT/s or more..... hence another no need to upgrade ram to begin with...........

Unless you itch to buy, like me, jumping from corsair3000 to GALAX3600, but the performance gain cannot be felt when in game :( ...... performance gain only felt when booting PC in first few days or swap, plus some heavy ZIP compression decompression

Overall is not major WHOOAAA for me......

But CPU upgrade from zen1 to zen2 is significant, felt even after 3 years later. If you jump to zen3 I think is GODMODE good feeling. Ram upgrade ........ becomes no feeling.

It should be this one: https://www.gskill.com/specification/165/170/1535961634/F4-3200C14D-16GFX-Specification But I have checked it out with the zemtiming as you suggested and seems bad: https://cdn.discordapp.com/attachments/1072856367632760942/1072856420913008660/image.png

Option-1
You need to turn ON the XMP profile in uefi bios in order to ma full use of the 3200MT/s MegaTransfer/second, running at 1600Mhz seen in bios and soft and zentiming etc. If it crash, means it's not compatible with taichi & cpu.

Regardless of all Options, must use the following voltages.
