Crucial Pro DDR5-5600 CL46 64 GB

Interesting effect in baldurs gate 3.

The only reason these aren't complete dogshit for gaming is because of Dual-Rank nature. I wouldn't recommend the single-rank unless you are reeeeeallly on a budget.

I buy hundreds of these because they're a sure way to get 128GB stable in a B650 motherboard without having to faff with manual timings. Slap in four sticks, EXPO profile 1, call it a day.

These are Rev C. First letter after the Dot. Not at the end in CPUz. Also the Die shot shows Rev C.

Example

CP32G56C46U5.C16D (Rev C) IC number CP98P

To be fair I have seen Pro OC reviews show CPU-Z "Rev D" as as XXX.D16D and XXX.M8D1 . Not many take the heatspeader off to look at the actual numbers. It should be (Rev D) IC number D8GCD

@Raven Rampkin review has been updated to reflect that these are indeed Rev D. I was mistaken. Thanks for the insight!

i'm pretty sure default voltage is 1.35v when expo is enabled, so after you enable expo, you manually turn them down to 1.25v? im a little confused

My bad you are of course correct. It is 1.35 indeed

@ir_cow my ram, same as his does around 44-49 celsius, sometimes 51-52 celsius in certain games. just wanted to confirm, is it worth investing in a ram cooling fan? I was thinking of getting a 80mm cheap fan, and gorilla gluing it to a piece of my pc case to direct cool air at the ram. not sure if it's worth it or not. i want my ram to last a long time though, like 10+ years with no degradation, any thoughts on that?

@Space Lynx spoiler from the temperature testing article I've been doing. the Temp Sensor on the RAM is Right next to the SPD chip in the top. Pretty much 7-10c lower then the DRAM ICs. So your actually ram ic is in the 58-62c range.

Active cooling is for when you want the lowest CAS and tREFi values for the most part. You'll have to wait for the article for details.

well, I am not comfortable with those temps for ram. I am going to look into some cooling solutions, if you could include some creative and standard cooling ram options for that article or a future article, it would be appreciated.

Corsair has a ram cooler for $25, but it won't fit with an air cooler, only AIO's.

ir_cow seen you ,mention a few times that you think when high clocks arent achievable its usually the motherboard to blame, do you still have multiple boards to hand as am curious when you testing RAM, do you find it can perform the same on every board, or you noticing its only the higher end boards that get the results you publish?

 

[ir_cow]

@chrcoluk I still do have multiple AM5 and 1700 MBs. Only one Z890 so far and a X870 coming soon.

While I think there can be a clear "winner", it depends one what you are trying to achieve. First of all, QVL lists are completely worthless for the top range. The vendor is saying it worked with X brand using our nice binned CPU at unknown voltages for unknown amount of time.

I use the "top end" OC motherboards for mostly convenience sake and to keep the comparisons the same. If the ram can run at X speed on another motherboard, the difference can be upwards of 3-5%. Lose or gain 100-200pt consistently in R23 for no other reason than a MB swap. Could be small auto default settings like CPU power limit, or simply one vendor has aggressive DRAM sub-timing auto applied as their defaults. I wouldn't say it's drastic enough to recommend a single brand or series over another unless your trying to run a certain speed beyond what is typical on that chipset.

As a example, I don't know of any Intel Z690 4-slot motherboard that can do 7200+.

The PMIC and voltage stuff can do 100c+ according to the data sheets. RAM ICs 85c for JEDEC. While lower temps will prolong the lifespan of said components, I don't know how much of a impact it has long term.

I think active cooling is great and I wish ram fans came back like the DDD2 days.

My RAM runs so warm is because of 2 factors.

1. Board is fully populated so the Chipsets are always warm. Especially when I game with a drive connected to the chipset.
2. I have 2 5.0 MP700 drives. Blame the TPU reviews, it is also why I bought like 8+ NV2s for builds.

I have a Corsair 7000D Airflow and I kid you not when I looked at the front filter it was covered in dust. Cleaning that led to a 7 degree drop in all temps. The GPU is water cooled so all of that heat has the Window open at 9 Celsius outside.

AMD: we recommend DDR5 6000 CL30.

Crucial Pro: best we got is CL46.

After tuning, rfc is actuslly quite good. Much better than samsung and better than all hynux except A-die. 150ns is not bad. Bummer that primaries and max speed is so low.
