Ram upgrade

[Ebony Falcon]

Looks for some good ram with good out the box xmp performance, 

how do those look

probly won’t be overclocking apart from enabling xmp and then il try a bin or 2 higher to see if it works on the speed but won’t be messing with timings 

 

I found this g skil 4000 cl18 

would this be a good kit

Yeah, that's a kit of B die so it should overclock pretty well. It's an insanely expensive kit of B die, to the point where it would make sense to just return your current motherboard and go for a kit of DDR5 instead, but it's a kit of B die nonetheless. If you wanted to just enable XMP and be done with it, that kit is pretty good. If you want to try raising frequency though, it's pretty pointless, 12th/13th gen CPUs top out in Gear 1 (where you get the best gaming performance) at about 4000MT/s, so while it's technically possible to get a higher speed kit, it's not really worth while to do so.

 

That said, spending ~150 pounds on a 2x8GB kit of RAM is a really hard sell at the moment, 2x16GB kits that aren't really that much slower are pretty easy to find, and you can even find decent speed 2x16GB kits of DDR5 that will be faster than that kit of B die for that price if you have the option of returning your board and getting a new one (given that according to your sig it's a Z790 board, I'd say that you're still likely within the return window). It would work, but it's not really a great use of money. Either stick to your current 3200C16 kit your running or make the move to DDR5, a high end kit of DDR5 just doesn't make sense.

A shit I thought it was 32gb 

what’s a decent 32gb kit to buy I need more ram anyway as in 32 gb and would like something to just enable xmp

If I added another 16gb 3200mhz kit would that go into dual rank as it’s using 4 dimms? Would that help eliviate some bottleneck ?

Assuming you're buying from Ebuyer, this is what I'd get

https://www.ebuyer.com/957347-corsair-vengeance-lpx-black-32gb-3600mhz-2x16gb-ddr4-memory-kit-cmk32gx4m2d3600c18

 

It's nothing special, but it's pretty cheap and should give fine performance.

Yeah, if it works it will work as dual rank. 4 DIMMs in the 3200 C16 bin is pretty sketchy since you're likely run into mixed memory which doesn't always work, but it doesn't usually become that much of a challenge until you get to 3600MT/s+, though it's still not impossible to run into compatibility issues (speaking from experience, I've got two relatively new RAM kits across a couple different boards will not POST together reliably).

3600 should be a nice bump in performance ? My price range is up to 150 for a 32gb kit and I can buy from anywhere in the uk 

[Ebony Falcon]

What about these ?

It's not gonna be much of a performance bump. It won't be nonexistant, but it's also not likely to be noticeable, and realistically the benefits of dual rank would outweigh the benefits of 3600 C18 vs 3200 C16. 

 

Sticking to Ebuyer (I'm not from the UK so I don't know the sites you can really shop at), this kit is guaranteed dual rank, plus happens to be 3600 C16:

https://www.ebuyer.com/1285920-kingston-fury-renegade-32gb-2-x-16gb-3600mhz-ddr4-ram-black-kf436c16rb1k2-32

 

This kit is slightly cheaper yet also guaranteed dual rank, though I'd spend the extra 7 pounds. 

https://www.kingston.com/dataSheets/KF432C16BB1K2_32.pdf

 

I wouldn't really go above the price of the 3600 C16 dual rank kit, since above that price you start getting into the too expensive to make sense kits and the point where you should really just be buying DDR5.

How do you know there dual rank ? Ok this looks good option as it’s 3600cl16 and dual rank

Kingston publishes datasheets for every memory kit they sell, including the XMP profiles present on the kit, the JEDEC spec the kit supports, and the memory kit organization.

 

https://www.kingston.com/dataSheets/KF436C16RB1K2_32.pdf

 

The datatsheet for that kit says it's 2Rx8 based, meaning it is in fact dual rank.

Awesome 3600 dual rank should be nice little bump and I need 32gb anyway and il try sell my kit for 40 pound or something

This apears to be a typhoon burner read out of them, if I were to have a go at the overclocking how does Hynix d die do ?

It's usually referred to as DJR, and it's pretty OK. It's not super consistent, but the good kits clock to the moon (almost all DDR4 frequency world records are done with DJR at the moment), but it doesn't tighten up much, if at all. It scales a lot with voltage, but also runs pretty hot, so you want a fan if you want to try going for some high frequencies, though feel free to run up to 1.65V with a fan as that's where G.Skill validates DJR based kits for their lifetime warranty.

I know u said it won’t tighten but would I have to loosen it to reach higher frequency’s or just pump voltage ?

For high frequency, yeah you'll likely have to loosen out the primaries a bit to get higher frequencies. For frequencies like 4600MT/s+ you do need CL19-26-26-56 (not 100% on the tRAS, though the others are XMP settings) and raise the voltage to ~1.55V to get it to work and be stable.

Ok il get this ram and try get 4000 ish with decent timings

With 1.4V 4000MT/s CL18-22-22-42 should almost certainly be possible.

Possible without additional cooling ?

Yeah, you don't really need additional cooling on it until you get to 1.5V, at that point it's not strictly necessary for the health of the memory but it tends to stop scaling above 1.5V unless there's active cooling.

Ok il order this ram today and have a go when it comes 4000 I’m gear one seems to be the best performance from what I seen on raptor lake ddr4

Also found those for 170

It is better, but I have a very hard time recommending a DDR4 kit over ~120 pounds, since the main reason to be going for DDR4 is because it's cheaper than DDR5, and at the ~120 pound mark you start getting the ability to buy decent DDR5 (5600MT/s+) which does just perform better than DDR4. 

 

I'd just stick to the previously recommended Kingston kit, it's not really worth the price increase.
