DDR5 64GB RAM

VinylRichTea · 17 Aug 2023 at 16:39

Bought some Kingston Beast RGB RAM 5600 64GB, have to say it's a great overclocker, currently have it at 6800Mhz, and it will even boot at 7200Mhz however my biggest issue is heat, holy crap running the TM5 and OCCT tests it was chugging out more heat than my CPU! CPU was around 60-65C on average and each stick was throwing out around 70-72C. :eek:

Does anyone have a similar experience? Recommend RAM coolers perhaps? Change the HS on the RAM possibly?

Sorry all, I've not replied sooner, as I've been on holiday.

Got it sorted, bought this dual RAM cooler from China on eBay for £15, screws into the motherboard (need to remove 2 screws and install standoffs) and works a treat, it's not noisy either compared to the rest of the fans and looks fairly decent. Temps are now max around 55-58C (depending on which stick) while running testmem5 Absolut profile for 6 hours straight. Got it at 6800Mhz at the moment at C34, need to do a bit of tuning with the secondary timings though as the latency is average, however, no problems at all. I'm aiming for 7200Mhz but I've ordered some hybrid copper heat spreaders from the Chinese app, will keep you updated.

you going to need some AIR flow on them or back off.
what voltage are you running

I've got it at 1.265 SA, and 1.43 DDQ & VDDQ. Mem controller voltage at auto.

What's the real world benefit though?
More fps in game?
Better render times?

What are you attempting to achieve?

Raptor Lake scales extremely well with RAM speed but tops out at around 8200-ish (which is only possible on 2-DIMM boards at the moment) so the faster the RAM, the better FPS and performance you get, unlike Ryzen where the performance tops out at 6400Mhz even though the new AGESA BIOS allows it to hit 8000+.

Hi there,
Which version did you buy? After 64GB that will do 6000 at CL30 or better. I’m assuming these are Dual Rank Hynix A Die?

I'm guessing if you are aiming for 6000Mhz you've got an AMD chip. I bought the Kingston Beast RGB 2x32GB, 5600MHz C40, don't quote me but I think the C36 (Expo) and the C40 (XMP) are the same A die chip BUT I'm not sure all are A die, some could be M die so it might be a dice roll but with a good chance. I could get 6400-6600Mhz at C32, so I'm assuming 6200-6000 you could get it at C30 but it will still get hot and need cooling, especially after a period of time and start to show instability/crashes. I'm currently on 7000Mhz at C34 100% stable, one more push and I can get it to 7200Mhz but tuning DDR5 is painful. :rolleyes:
