You know once upon a time i was an expert in these things :D alas these days im so out of the loop its not funny.

I have 2x sticks of corsair vengence 6000MT ram and i just picked up 2 more from a guy selling locally, what i didnt check was the fine print!

The new set is XMP and the original is EXPO (im on a 7800X3D)
Old chips are SK Hynix new ones are Micron.

Now my question is, im not after the crazy fastest performance of all time, i play some games, i have a 4070ti, but im an old man.
1)is this speed THAT bad?
2)Can i juice it without expo/xmp without spending my life in the bios?
3)is the best option to get 2x32Gb sticks and just sell these 4 on...

Opinions?

Uncore Frequency 1796.3 MHz
 
I have 128GB (4x32GB DDR5, two matched pairs, and the serial numbers are off by 2, so someone managed to get the other pair in between my two sets) and it runs at 3600Mhz with a 7950X. And it doesn't really experience issues for performance (It's not noticeably slower than my 9800x3D rig with 64GB DDR5 at CL30 6000Mhz). But another of note, is that the 7000 seris of chips can't run 4 x Dual Rank RAM at full speeds anyway, they will always default back down to 3600Mhz. So really you're looking at either:

A. Faster Memory settings at lower total amount of RAM (96GB via 2 x 48GB DDR5 at 6000Mhz CL30, etc)
B. Larger Total Memory run at lower speeds of 3600Mhz (maybe if you tinker, up to 4800Mhz) (128GB+ via 4 x DDR5 combinations)

If you're not going to be using lots of memory (You'll know if you really need it), you might as well just head back down to a smaller amount of memory ran at faster memory speeds instead. Although the x3D chips design does mean they're not as pushy about memory speeds as the normal chips are.

I don’t understand what your config is. Are you running 4 DIMMs or 2?

You should only, really , run 2 DIMMs for DDR5. You might be able to manually configure it but you’d need to know what you are doing first.

Kind of hard to say 100% because nobody tests at such a slow speed, but probably not, no. The X3D is pretty good with slow memory, likely because the massive cache helps.

However, it might well impact your lows when you are GPU-bound and top-end FPS/framerate consistency when you're CPU-bound.

2)Can i juice it without expo/xmp without spending my life in the bios?
Yeah, you can do a 100% manual config, but it is more complicated because you can't just set DRAM frequency and DRAM voltage and call it a day.

3)is the best option to get 2x32Gb sticks and just sell these 4 on...
For an easy life, yeah.

I would imagine you can do a lot better than the speed you're getting. If you can get them up to around 5000 then the performance loss would be minimal for the most part.

4 sticks of memory in current motherboard can be an utter nightmare. I have had 4x Sticks of 48Gb DDR5 5600Mhz run fine at EXPO but 32Gb modules are a nightmare. Some motherboards will support the 4 sticks better and have them on their QVL others dont. Normally just setting the memory to auto will result in the most stable speed without doing a load of messing about and often gets 3600-4400MT/s.

Thanks both, Is there a good guide anywhere to modern bios RAM settings? As i say im not a novice, was overclocking 20 years ago on an fx-53!! BUT the current RAM settings on a modern mobo are mind boggling i dont even know where to start (we dont lock the FSB multiplier anymore...one for the grey beards :D)

If i knew how to derive the settings for my RAM and get the MOBO to put them in im plenty happy to run well below rated

The only memory overclocker I'm aware of is buildzoid (actually hardware overclocking on YouTube), but not sure if he has a how-to guide for a DDR5 newbie.
