After running the benchmark with CTR 1.1 beta 7, it says I can go higher. AMD Ryzen 9 3900X and Ryzen 7 3700X Review: Zen 2 and 7nm Unleashed First 7nm CPUs bring the power. I have never overclocked a AMD. I read a guide somewhere and set all cores to 4.5ghz and set a static voltage of 1.3v until someone told me Id possibly degrade my chip by doing that (had it … In theory you could tinker further using this method; reducing the voltage further may allow for cooler running, and you may have more luck in increasing frequency, it really comes down to the “silicon lottery”! Hi i currently have my Ryzen 3900x OC to 4.2ghz with 1.1volts. Ryzen 3900X with a Corsair H100i rad and MX-4 in between. It depends if you have the voltage hardlocked to 1.2 or Auto. AMD's 3700X en 3900X hebben alle andere troeven in handen. Ryzen 3900X voltage Hello, I recently acquired a 3900x CPU and I am experiencing several cases that I do not know if they would be normal. I recently put together a Ryzen 9 3900X system with a Gigabyte Aorus X570 Elite Wifi motherboard, 32 GB of G.Skill RipJaws 3600Mhz CL16 RAM, and a Scythe Fuma 2 cooler. The first is the high idle voltage, while idling the voltages do not drop below 1.38v, ranging from 1.44v to 1.38v, although I have to say that this is caused by the iCue software. Certain settings in BIOS when set ,do not get reported on desktop correctly with third party software but the voltage will still be the same as set in BIOS. Has it failed before? Just rarely for 1 second during a boost. Undervolted AMD Ryzen 9 3900X shown be just 23% slower while drawing 36% less power at 1.00V Vcore The Ryzen 9 3900X offers a good scope for undervolting. Reactions: Nightfire, Ebernanut, Nobu and 1 other person. I heard Steve at Hardware Unboxed toasted his 3900x because of voltages and the chip is dead. The 3900X ships with a base clock of 3800MHz and a single-core boost clock of 4600MHz, so a reasonable target, with a sensible boost to voltage, would be around 4.3 - 4.4GHz across all cores. Any you recommand any BIOS settings or Rzan Master settings? … Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. Asus board will idle in 1.4v mostly, yes it does dip to sub 1v but lot less than asrock board. Ok, Im gonna do another post about this because I really want to fix this issue, the thing that I want is simple, I just want my voltage to drop in idle, I dont want to use 1.4 when browsing and things like that. I have seen various youtube videos about BIOS settings but also about people using ryzan master in combination. As I said, swapping out the CPU cooler enabled me to push the Ryzen 9 3900X harder and faster, but failed to reach the advertised maximum boost clock of 4.6GHz. AMD Ryzen 3900X I use reaches a boost frequency of 4,500 MHz and usually operates around 4.20 - 4.25 GHz on all [or most] cores. Check with CPU-Z to get the voltage you are looking for that will match what you set in BIOS. You would think that AUTO is the safe bet , no over clocking etc , a base to start from . It does support 3900x cpu in specifications. Like way too high. AMD Ryzen™ 9 3900X desktop processors from the AMD 3000 series are the most advanced desktop processors in the world for elite gamers. The 7nm revolution has arrived, join us as we review the new Ryzen 7 3700X & Ryzen 9 3900X processors from AMD. These voltages are perfectly safe for your CPU but I understand why you are concerned as they are higher than they need to be for normal smooth running. Hey guys, I'd like to get the maximum out of my 3900X - looking into a min. Ryzen 3900X iCue voltages. It runs an AMD Ryzen 3900X on an Asus ROG Strix X570-E Gaming mainboard, a DARK ROCK PRO 4 air cooler and 4 fans in the chassis. My cpu voltage is set on auto, I read about it and it seems to be okay and in Ryzen Master it doesnt show as 1.4 anyway. Which got me looking at voltages and the BIOS had the CPU at 1.45ish for god knows what reason. They were both stable at 4.35 GHz, the 3900X needed slightly less voltage at 1.4 V where the 3700X needed just a touch more up to 1.45 V. The happy medium was found to be 4.2 GHz where they would both run stable and cool with only 1.25V and just like the previous generations the voltage scaled quickly as the frequency went up from there. 1. Ze zijn sneller, zuiniger en even duur als hun directe tegenstanders, maar goedkoper dan hun prestatieconcurrenten. Depends on if any applications you use see benefits from bumping that 3.8 up to a 4.15. AMD Ryzen 3900X Corsair RM750X (niet 2018 variant) Mijn moederbord heeft voor de CPU zowel een 8-pin als een 4-pin connector, ... Lagere kwaliteit silicon > hoge voltages om zelfde freq te halen en 't amd boost algoritme 'weet' hoeveel voltage hier binnen dan 'safe' is. Why don’t you read through this forum thread and see if it can answer your question? The 3,800 MHz & Cas Latency 14 is an extremely impressive combination at 32GB with such low voltage. I just noticed that temps were idling at 70ish and immediately hitting the 95c thermal limit on load. hi I have doen a fresh clean install of Windows 1903 Installed iCue software on 30th September from Corsair website After installing the icue software voltages on CPU go from 1.0v-1.1v to 1.3v-1.4v When i kill icue voltages return to normal. How do you guys overclock a 3900X? Learn more! My averages are always 1.4v. so a 20 thread intel at 5.3ghz still loses to a 3900x at 4.3ghz on 24 threads i would really thought the ground would been made up with the 1ghz more clock speed per core. Normally 1.45 is where voltage starts to be a problem causer, as running this voltage over long periods can degrade the CPU faster than normal. I am talking identical setup other than the CPU 3600 vs 3900x in the Asus setup. I know it is like lottery though. On asrock idle voltages are miles better than asus in windows. 2. Check your voltage if you run high temps on idle!!! Even when using supposed “safe” voltages as a maximum input limit for overclocking via BIOS, it’s possible that the motherboard is feeding a significantly different voltage to the CPU. I noticed a number of sites and channels are reporting that the AMD Ryzen 9 3900X 12-core, 24-thread processor can be run at full clock speeds with just 1.00V on the CPU VCore. Price? Ryzen 3xxx CPUs tend to run at veery high voltage even on idle. Low 50s on idle. Now at the bottom click on "Save Profile" and then click on "Apply & Test" and the system will reboot. Is that safe? I updated the BIOS to the latest version, AMD Chipset, AMD Balanced power. By Paul Alcorn 21 November 2019 These targets and hopes are somewhat based off our success with overclocking the Ryzen 1st and 2nd Gen. CPUs as well as the Threadripper processors, which you could argue are more akin to the 3900X. 1.2 is totally safe. Hi, my PC was was configured and built by a local PC dealer. 3900x - Danger High Voltage - Epic Wins - Roshtein - Forum ... Birke420 My 3900x was getting fairly low benchmark scores at stock settings, ~6700-6800 in Cinebench R20. With the H100i, I topped out at 4.4GHz with a 1200MHz memory clock and voltage set at 1.5V. In my opinion, the XMP profile doesn't make sense, though, as you will actually see a gain in performance when you lower the speed to 3,600 MHz (as I have hammered down your throat this whole article). In power save profile the chip idles around 40 with my room being about 29c right now. 4,3 or 4,4 GHz overclock. Setting the Vcore manually to the same value ( 1.2v ) you would think gives the same result , but increasing the voltage the 1.25v gives a better and cooler result to autos 1.2v , So AUTO may be adding a positive offset value somewhere else. Then they run hot. I managed to overclock my 3900X to 4.3GHz across all cores – a big improvement from the 3.9GHz I achieved out of the box, but still a little short of AMDs claimed 4.6GHz. 7nm Zen2 processors have arrived. In POV-Ray, running the 3900X at a flat 4.3GHz at 1.35V gives it a 8.2% performance boost over stock. like this. What makes you think this Mobo is below than average quality? This is due to both the Ryzen 2000 and 3000 series of CPU s having their voltages set notoriously high by the BIOS. ASRock X370 Taichi. As you will see, the CPU is limited to a maximum of 1.3 Volts and essentially you are just seeing how much clockspeed you can squeeze out of those 1.3 Volts. When the system is not under load then of course the operational voltage will decrease. I guess pushing things too much is an asus thing. (plus my previous SSD and an EVGA GTX 1060 3GB) Overall I'm very happy with … So here's mine: Cooler: custom loop ek strike cpu block Batch: not sure Voltage: 1.25-1.30 depending on load under 65c in everything but prime95.
