| From: Nicholas Krause via talk <talk@gtalug.org> Thanks for thinking about my problem.
| Yes, Hugh will run into problems then of getting that speed. The JEDEC default | profile is 2400mhz | from memory. Yes, that is true of the modules that I bought that claimed to be DDR4-3200. That is in fact what I said in the initial message. | Not sure how locked the Bios on his Thinkpad is. It seems that | lots of people are | reporting XMP enabling not being possible. I don't know why they would lock | that considering | RAM Speeds needing XMP for the full speed, for the last decade or so. This is a ThinkCentre M75s gen 2 Small Form Factor machine. It takes desktop DIMMs, not SODIMMs. XMP is an overclocking technology from Intel. One should not need overclocking the get the advertised speed. | Not to mention AMD chips like faster RAM up to 3200mhz from memory. There are | suppose to be | performance differences there as well. This seems like a very bad manufacturer | decision if | this is occurring with Lenovo Laptops. This is a bad decision of the RAM vendor: misleading advertising. The computer does drive DDR4 3200 RAM at 3200: it came with an 8GiB DIMM. Yes, AMD Ryzen processors have traditionally have clocked certain things (like the cache) at the same rate as the memory. That's why I don't want to settle for DDR4 2400. | Hugh, are you just using the ram for web browsing or multitasking? If that's | the case I don't | think the 800mhz bulk is going to be a big deal. It's up to you but Ryzen only | wants faster | ram when I checked for applications like databases, GPU programming e.t.c. So | if your fine | with the lower speed and I'm assuming that's the use case it should be | alright. Of course it will be alright: it is replacing a 9 year old computer which is still OK. But I want what I paid for. Your characterisation of workloads using high physical memory bandwidth is a bit odd. --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
