Speccy ram speeds frequency vs latency11/13/2022
A while back, I was using a 2 piece (2x2GB) Kingston HyperX kit in my system. You will need to be in "advanced" mode from the exit menu in order to do this.Īssuming your memory movement testing was well conducted :P there are further possibilities of having a bad CPU, bad mobo that could cause something like said: If that doesn't work: Manually set the "main" details of your RAM speed (look at the JEDEC 4 stuff from your pictures for what you should set, the rest can be left on auto). Speccy ram speeds frequency vs latency manual#Look at your user manual on page 2-15 for a memory auto-configuration button that might help if the memory isn't working after the previous step. Speccy ram speeds frequency vs latency tv#You will need to then reset time/date and any other customized settings like boot order or default graphics since you have a monitor and TV connected. Update BIOS (manual 3-44 or -45, for USB note that it has to be FAT16/32 formatted) and then choose reset to optimized defaults. Note any changes you've made to the BIOS (boot order, for example) The process I'd try here would be something like: Speccy ram speeds frequency vs latency windows#If your BIOS doesn't see it, I don't think it will be presented to Windows correctly, so your efforts should be focused on BIOS corrections/testing. Anyone have a fix to this issue or know of some other things I could try? I'll post some screenshots of my Speccy overviews and RAM information as well as some possibly relevant windows things below.Īll sticks are identical (they appear completely identical from speccy, which makes me doubt it's accuracy)? Any overclocking attempted? All info below has extra detail, don't feel like I'm being condescending I noticed when in BIOS that the Available memory shown was only 8GB when I have 4x4GB sticks inside the system but if I went in to check the data on each individual DIMM slot they all showed having the 4GB stick in them. I've attempted Re-seating the RAM, trying it in different configurations, testing each stick individually in each slot and both enabling and disabling memory remapping in BIOS and have still not had any luck. I did some searching on google and attempted some of the trouble shooting things that were on other forums to no avail. I added an additional RAM kit into my system yesterday in an attempt to boost my amount of available RAM, however after booting up the system I noticed that Windows was not detecting the new RAM placed in the system at all, however Speccy and CPU-Z both detected it. The increases frequencies and lower timings are achieved at the cost of higher voltage.Hey Icrontic. That's significant.Īlso I'll note that JEDEC is standardized at 1.2V and most of the XMP profiles you'll see are 1.35V. Latency is another thing with XMP profiles, that are pushing much lower than JEDEC standards. Especially on AMD Ryzen platforms, as the infinity fabric runs 1:1 with the memory frequency and scales up with it. Latency wise, this is a wash, but factoring in bandwidth the 3600 kit is a better option at 28.8GB/s, vs 25.6GB/s. Latency is basically response time, lower is better.ĬAS \ Frequency * 1000. Generally as frequency increases so does latency. You also want to factor in latency as well. Now, that's theoretical and you won't likely hit that on a benchmark, but I have hit over 60GB/s read dual channel overclocking a Patriot DDR4-4000 kit. Best wishes to you! : in mind you're running in dual channel and you're theoretically doubling that number. I think I somewhat understand now (or at least I have an idea of what's going on internally). Single channel it's only 1600.Īgain, thanks for your well-explained answer. They label it as 3200 memory, when in reality it's 1600 memory that "becomes" 3200 IF one uses two of them in dual-channel mode. That's kind of what I see here in RAM speed ratings. It an industry-wide "fake" rating that almost everyone uses. In reality OHMs have nothing to do with power, since ohms are a rating of electrical resistance, not electrical flow. It reminds me of the guitar industry, which rates guitar pickups by OHMs as a rating of power/volume. but he didn't go into detail and I didn't think to ask him I just took it he knew what he was talking about (and evidently, he did). I'd asked him, "Which is better, for me to buy a single 16g stick or two 8g sticks?" He said two 8g sticks "Because they're faster if used in dual channel mode". I'd actually had a tech hint at that when I bought the RAM but he didn't explain why. They call it 3200 memory, but if one only uses one stick they'll only get half the speed of dual channel. In my mind, this is kind of the computer industry "cheating" in a way. I had actually wondered if it was something like that. Thanks TS! That was an excellent explanation.
