Patriot Viper Xtreme 5 RGB DDR5-8000 CL38 2x 16 GB

[ir_cow]

Patriot takes DDR5 to a whole new level with the Viper Xtreme 5 series, DDR5-8000 is finally in consumer hands. For PC enthusiasts and the XOC crowd, Patriot includes three XMP profiles to get you started. With a side of some serious overclocking, follow along as we break down the benefits this memory brings to the table.

nice to see three xmp profiles, that should really be standard imo.

I would liked to have seen a high match between the rgb and non rgb kit to see if it is possible to get better settings on the non rgb due to better signal strength

BTW any words on general availability . cant find them in Denmark yet

 

[AnarchoPrimitiv]

Can you do an "overclocking" section where you leave the frequency at the stock XMP profile (so 8000 for this kit) and just get the timings as tight as possible and see the performamce result?

I sent Patriot Rep a PM asking. Will update with reply once I hear back.

None RGB does have a higher OC potential due to better signal integrity due to less interference (as I understand it). The problem I think many face (including myself), is if you aren't going for records doing XOC stuff, it is unlikely to affect you. The 13900K I'm using effectively is limited to 8200 for 2 DIMMs and passes all the tests. Not a motherboard or memory limitation, but the CPU IMC. Doing a a proper test right now would require expertise beyond what I can do.

Would need a bigger sample size also since 1 kit isn't a guarantee they all perform the same. Next if you used 1 DIMM, and disabling half to reach DDR5-10,000+ is probably the only way you could do a proper A/B testing at this time. Beyond showing that yes non-rgb is better with data to back it up, I don't see the point for us normals.

No voltage change, or is that allowed?

 

[msimax]

that set "should" work nice with amd

 

[b1k3rdude]

So depending on price, what about underclocking and tightening the timings for AMD, eg 6000MT/s and say CL32.

Or has AMD enabled stable memory speeds above 6000 with an AGESIA updatdate now..?

Please share some pics of your bios settings of memory as well - thats a nice build

Yes, they fixed the 1:2 IMC ratio. But you get a latency penatly for running IMC at 50% of RAM clock so performance wise those high clocks don't change much on AMD platform.

You can buy retail kits that are DDR5-6000 with 30-39-39-96 timings and easily get them to 28-36-36-50 without much trouble. Don't see the point in paying more to get the same results. The benefits of buying a higher binned kit is that eventually you may be able to run it at those speeds.

....Or has AMD enabled stable memory speeds above 6000 with an AGESIA updatdate now..?

The cut-off for Ryzen 7000 CPUs is 6000-6600 MT/s for memory 1:1 Ratio. My opinion on the subject just like the previous AMD (DDR4) generation, Go for the maximum the CPU IMC can run in a 1:1 ratio configuration and the lowest timings possible. Just for an example, 7200 MT/s in 2:1 trails behind 21%~ in the benchmarks I've run vs 6000 MT/s 1:1 (low graphics). However once you are GPU bound, like playing at 4K max settings, they are within margin of error and to be frank, it kinda doesn't matter what you have. Though technically, the 7200 MT/s kit is worse in synthetic benchmarks and 1% lows (some games).

So DDR5 can ramp up voltage a lot and still safe for daily.

Good idea on the multi XMP on DDR5, so if someone has a crappy IMC or board for the best XMP, there is slower fallback options, I like that.

I thought new Chipsets fixed that?

SK-Hynix can, but if you try 1.6V on Micron, it will probably die immediately lol.

Fixed the 6600 MT/s 1:1 ratio limit? Nope. That is a CPU IMC thing. Though , never say never.

The update main purpose was to get Gear 2 (2:1) working now is all. Previously it pretty much didn't work at all.

How'd you break a kit?

The stupidest way possible lol. Sheered off somes SMDs by putting into the slot wrong.

Oof!

use those settings but the main thing is voltages your cpu likes and it varies chip to chip
vdd 1.575 vddq 1.480 cpu
soc find your sweet spot as well as vddio

 

[ir_cow]

Ohhh you got the elusive Tachyon MB impossible to find for sale yet unfortunately. When it does show up I'm buying it!

I saw posts from hicookie hitting 9000 MT/s with it. Good stuff.

how about 9536 MTs

Would this work on AMD with their new speed gear?


Makes me wonder what the frequency is where it's back in a happy place again

Those look like some happy settings for AM5, M/F/U clk all OCD pleasing.

If you have a nice CPU IMC and a 2-slot MB, yes. Otherwise it is iffy. Like I can boot DDR5-8000, but it isn't all that stable. haven't tried the C AGEAS revision yet though.

It'll be fascinating to see how that changes over time, and if a new second sweet spot gets smoothed out
