Patriot continues to expand the Viper Xtreme 5 series, targeting PC enthusiasts and the XOC crowd. This DDR5-8200 kit includes three XMP profiles to really dial in the performance. We pushed this memory to DDR5-9000! Follow along as we break down the benefits of this kit and how you can take advantage of it.

I learned 24GB sticks was a thing a few weeks ago and I'm still weirded out by it.
 
The DDR5-9000 result is encouraging for these H24M kits to have "legs" to get improvements from better IMC silicon on future platforms
 
Will have liked the test on AMD with 8000MHz Cas 34 & 6200mhz CL26 if it was possible to make it stable with that kit. 2X16GB is to short now 48GB look just ok not to much.
 
Not happy they ruined the look, the steel series was much better looking.
 
Aren't these the kits that have a XMP setting called XMP Tweak that changes all the timings? I think it would be a good test for the overclocking section. I've got the Patriot 8000 48G kit and set it with the timings of 7600 XMP Tweak profile and a manual bump up to 7800.

These are the flagship ones without RGB. Pretty sure they still make the ones you're talking about.
 
It might be possible to get higher than 9000 if you tweak impedences, but I can understand it probably isn't worth the time when you're already doing a lot of other work. I have the 2x16GB version of this kit & bin and it does very well. TRCD 43 limit at 8000, 46 & 8800.

Patriot is pretty competitive on price in the USA too ($145USD incl. tax atm).
 
I plan on waiting for the 15900k before I build a new desktop.
I will only have SSD storage and a HDD backup.
What DDR5 RAM should I get for it?

Wait to see what speeds next gen Intel can support. Unless you plan on overclocking, in which case buy a decent bin of Hynix 16Gbit A-die or 24Gbit M-die

XMP-Tweak / XMP-I is a ASUS thing, similar to Gigabyte High Bandwidth Support or ASRock Aggressive mode. It ignores everything but the primary timings SPD and inputs whatever the BIOS team have implemented. I've told ASUS that it's confusing to users to have XMP-I, XMP-II and XMP-Tweak, when XMP-II should actually be the default one. For testing I always use the "defaults"(XMP-II) because it represents other motherboards too. Same results to typing in the SPD data yourself.

Essentially you took 7600 memory, changed the frequency to 7800 and enabled the motherboards Secondary and Tertiary timings auto tweaks. These changes aren't that aggressive compared to manually setting these values, but I still suggest running some memory stability tests just in case.

Ohhh I forgot about impedances. I remember now messing with it a ton to get Dual-Rank DDR4-4000 : 1 to boot on AMD. I haven't been able to get y-cruncher to pass above 8600 yet :/ 8400 is my daily limit before the voltages get out of control. Don't really want to run 1.375 V for SA.

I did run some tests, it was fine and passed. I wasn't sure if Tweak was a per kit brand thing or a mobo thing. I did it that way because I figured Tweak at 7600 with the lower primaries would be more aggressive than trying 7800Tweak and bumping to 8000, which both have the same primaries.

I saw something like that a few days ago. I just figured it was a typo. :laugh:
 
Am I missing something? I don't see any results for the AMD system.
 
I have CP2077 installed with the latest updates and was curios what kind of results would I get with my setup that has tuned DDR4. So in the review, the DDR4 3600Mhz setup got an average of 207FPS at 1080p with the High preset. My result was 242FPS average at 3Ghz core and 12Ghz mem on my 4090 and 240FPS average at 2.6Ghz core and 10.5Ghz mem. GPU doesn't fully load so that's ruled out. I also have a 13900KS at 5.6Ghz HT off and my DDR4 setup is at 4133Mhz with very tight subtimings. My results are interesting because its even faster than their tuned 8200Mhz and that's just not the case.

Am I missing something or are they testing differently?

Pretty sure the conclusion page explains that pretty well

Getting right into the basic compatibility concerns, 8200 MT/s is unlikely to even boot on AMD systems. With only a few AM5 X670 chipset motherboards that support 8000 MT/s, these higher supported speeds are a rarity. While 8400 MT/s support has been teased for select X870 motherboards from ASUS and Gigabyte, it doesn't matter which brand it is if the CPU cannot reach these speeds. Both the Ryzen 7000 and 9000 series share the same memory controller, which limits the chances of breaking the 8000 MT/s barrier. In the AMD test system, the 8200 MT/s XMP profile would not boot at all, thus no benchmarks were conducted. Do not buy this memory for AMD systems unless you plan on downclocking it and applying secondary and tertiary adjustments.

When I first got Cyberpunk, I had the 2080Ti and that week I was able to upgrade to the 3090. The difference was like night and day.
Can't wait to be able to run it on a 5090 to playthrough the added on content.

Yup there it is. I swear I was looking and I just over looked it. Thanks.
 
Could you add ADIA64 Photoworxx test? It's very sensitive to memory clock and timings.

Same sticks just the 8000MT's (my results btw)
