safe ram temps ddr4

This is more of a PSA for all of the beginning ddr4 Ram overclockers. i am using 2x16gb sticks 32gb total of corsair vengeance pro rgb, the temps are around 38c to 39c sometimes 40c is that ok?? However temperatures above 40 degrees cause stability issues and random errors. DDR3 memory operates at 1.5V, so running 1.5V on Haswell-E shouldn’t be a big deal, but we all know that lower voltages are better. i love low temperature. This is useful information for the community and we pretty sure that we weren’t the only ones that were curious how much power you could throw at the memory kit before the memory controller on the processor would being to get angry. [SOLVED] normal ddr4 ram temps?? Some chipsets like Sata controllers run 80-90°C and the voltage regulatory mosfets (VRMs) next to the cpu cooler can run upto 100°C when pushed. Legit Reviews contacted Intel about the safe voltage range on DDR4 memory and we received this response. RAM that gets too hot can lose stability, but I've only ever actually seen it happen on DDR1 (which has a way, way higher power draw). At least on DDR3, I find performance is equal or better than high tREFI if running low tREFI, to allow for better tRFC, tRRD and tFAW values. JEDEC committee members told us that voltage reduction is an important prerequisite for limiting power consumption and heat generation due to the increase in bandwidth. Press J to jump to the feed. You can bench under 50c. Legit Reviews contacted Intel about the safe voltage range on DDR4 memory and we received this response. On a zen system I've found the least amount to boot and maintain stability is best. Completely safe yeah. Eben Upton returns to the Pi Cast on Nov. 3, 2020! The amount of times I've had somebody argue with me over CPU temperatures and degradation is astounding. Is it okay to run an 8Gb stick of server ram with an 8Gb stick of normal kingston ram? I'm running mine at 1.425v and peak at 39c. i9 9900k 5.3ghz, GTX1080ti 2152mhz core, 4000mhz C16 RAM. 1.5V is a good daily limit of course, as most people want their RAM to last for more than single upgrade cycle.Temperature related errors occur far more frequently when running your tRFC/tREFI on the edge of stability. 1.5V is a good daily limit of course, as most people want their RAM to last for more than single upgrade cycle. And temps above 50 degrees Celsius can cause system crashes and huge errors on otherwise stable ram overclocks. Memory. I even had several people disagree with me about the ddr4 because it's temperature spec is 80 something Celsius. Is 25% of ram usage at idle normal? overclocking almost anything scales with temperature, dram isn’t special in that sense. Cookies help us deliver our Services. DDR4-3000 doesn't even need heatsinks tbh. Forums. Thread starter packersfan036; Start date Aug 28, 2019; Sidebar Sidebar. Most RAM doesn't even have temp sensors. 60c is a perfectly safe temperature for RAM. I've also seen 1.55v kill hynix AFR sticks in about 10 months. What's a good/safe ram temperature? Press question mark to learn the rest of the keyboard shortcuts. Copyright © 2002-2020 LegitReviews.com -- All Rights Reserved. For a while now I've been checking RAM temps in my builds. 1600x@4.1ghz/1080ti 2175 core/2x8gb samsung b die@3400.14,14,14. Yes i confirm this, happened to me, this is why you need fans above your RAM, like the G.SKILL turbulence. Technically, no “safe” (guaranteed) OC over-voltage but 1.35v or lower is best.” – Intel. From 40c to 50c I'll throw maybe 2 errors on stable settings. They are only a few °C higher than your average case temps, you'll also find that hdds and other components that actually do any work will run about the same. 20+ errors every few seconds on stable overclocks at 1.5v. Previous Next Sort by votes. Boldly going nowhere with ambient cooling. So ram at 40°C isn't an issue. DDR4 memory is very new and we haven’t been told by anyone what the safe range is for DDR4 memory, which is a bit strange if you think about it. Shorter refresh cycles keep the cells properly charged, at a small cost to bandwidth. Running your RAM at the lowest needed voltages to boot will often give better stability then just sitting 1.5 volts and trying to get it to stabilize. This is a pretty well-known fact for ddr4 and can be reproduced yourself pretty easily. JavaScript is disabled. I have never seen a situation where RAM has overheated without the user running it outside of the manufacturer's specifications. We also had one Intel X99 motherboard and Intel Core i7-5960X processor die an untimely death, so we were really curious if the higher than standard voltages played a roll in that situation. Break 50c and it will absolutely bsod in minutes under load. Unless you are overclocking the RAM or running it in a case with dreadful airflow, you'll be fine. Temperature related errors occur far more frequently when running your tRFC/tREFI on the edge of stability. All things overclocking go here. So, it sounds like Intel suggests a memory kit that uses 1.35V or less and that 1.5V is the absolute max for Intel XMP 2.0 certifications. RAM temps are not usually any problem. Is it normal for ram speed to go down when installing more. È un tipo di "memoria ad accesso casuale dinamica sincrona" (SDRAM), con una elevata larghezza di banda (DDR è acronimo di double data rate, dall' inglese "doppia velocità di trasferimento"). May 27, 2015 1,682 24 11,795 2. However, good DDR4 memory will run at 1.35v up to 3200. Aug 28, 2019 #1 i am using 2x16gb sticks 32gb … For a better experience, please enable JavaScript in your browser before proceeding. By using our Services or clicking I agree, you agree to our use of cookies. Ddr4 is rated for up to 1.5 volts 24/7 and temperatures of 81c before damage can occur. Its really only an issue if your water cooled airflow wise. Now you know what the save voltage range is for DDR4 memory! But that's no glass. Help Request - RAM Currently I have overlocked my Corsair Vengeance pro RGB ram from 3600 cl18 to 16-21-17-36 and im getting like temps up to 44 C on load. The memory controller in Haswell-E is the same one used on Xeon processors, so it can technically support both DDR3 and DDR4 memory. normal to only have 11gb available out of 16? “1.5v is the absolute max we allow for XMP certifications. Not all boards have that accessible though, and it honestly should never be needed. Hardware. The system doesn't need to function however, just not fail entirely. 8 GB used at idle, My ram lights turn to red for 3 seconds and then back to normal. It's DDR2 800 memory running DDR2 887 @ 1.9v if I recall correctly, in a … At 1.5v how much case airflow is required for under 50c and 40c? one Intel X99 motherboard and Intel Core i7-5960X processor die, 1.35V = okay voltage for overclocking kits, 1.5V =absolute max voltage allowed for Intel XMP 2.0 profiles and max suggested voltage. Doing some casual testing and observing I showed that random intermittent errors do occur much more frequently above 40° C. When pushed above 50° C Ram throws huge amounts of errors almost immediately once 50c is hit. For benching though anything under 50c would probably be more than kosher. Ddr4 is rated for up to 1.5 volts 24/7 and temperatures of 81c before damage can occur. However temperatures above 40 degrees cause stability issues and random errors. Increasing RAM doesn't my PC boot normally, 3600 mhz Ripjaw ram not working at rated speeds and not working at "normal" oc speeds. I would agree it's fairly common sense knowledge. 32 GB installed. “1.5v is the absolute max we allow for XMP certifications. More voltage more heat. packersfan036 Honorable. You need to treat your RAM well and cool them like you GPU and CPU, New comments cannot be posted and votes cannot be cast, More posts from the overclocking community. The actual 'damage' voltage is actually closer to 2V, JEDEC requires DDR4 tolerate spikes of 1.9V without harm. xmp is activated. However this is not we're the experts of overclocking you come to discuss their findings and what they're doing. And temps above 50 degrees Celsius can cause system crashes and huge errors on otherwise stable ram overclocks. One of the key features of DDR4 memory is that the supply voltage has been reduced to just 1.2 Volts, providing a 20% improvement over DDR3 kits that run at 1.5V. Learn to overclock, ask experienced users your questions, boast your rock-stable, sky-high OC and help others! Any DDR4 that actually has heatsinks should be fine even over 4000mhz - well over what's easy to hit. Dram degrades as well ya know. In recent weeks we have received kits that are running Intel XMP 2.0 memory profiles at 1.35V and 1.50V, which are both above the the ‘standard’ according to the JEDEC board. The voltage limit is mainly for the CPU though. In fact, there is a separate tREFI value for when your sticks exceed the max temp, which sets the tREFI time extremely low so errors don't occur. DDR4 è lo standard di memorie RAM sviluppato come successore delle memorie DDR3. The memory controller in Haswell-E is the same one used on Xeon processors, so it can technically support both DDR3 and DDR4 memory. 1.42v I can maintain under 40c passive cooling. Right now I'm seeing the highest temp I've recorded yet, on on a build with 8GB (4x 2GB) of older A-Data AD2800002GMU DDR2. You must log in or register to reply here.
