Hi everyone i'm just throwing this up as hopefully a short and easy to understand guide to p state overclocking on the crosshair vi hero motherboard (AM4/Ryzen). First of all don't be turned away if you don't have the crosshair! Most of this guide features the AMD common bios which should be common across motherboards (it is just up to your board manufacturer which options to make available in their BIOS). Why should you want to do this? Well as you may has noticed if you have overclocked your powerful new ryzen cpu that it no longer downvolts/downclocks when idle . This is because this is a fixed all core overclock. Which while good for performance, it is bad for: the cpu's lifespan, excess heat generation when idle and your electricty bill. A power state or "p state" overclock however will not only enable you to overclock above stock speeds but also step back down when idle (similar to Intel's speedstepping). Crosshair specific info: - This should be working on any BIOS revision later than and including 1002 (which at the time of writing is 1002, 0079, 0081, 0082 and 0083) - Update 0081 and later should be working with custom BCLK values (though i personally haven't tested this yet), 1002 must use default BCLK. As above i'm using the crosshair vi hero motherboard and BIOS revision 0082 but this should be fairly similar across manufacturers: Step 1: Always best to start with a clean slate so head into the bios and hit "load optimised defaults" Step 2: Head to the extreme tweaker screen and check everything is back to default and most importantly that the cpu core ratio is on "auto" Step 3: Head to the advanced tab and open the AMD common bios specification or "AMD CBS" for me Step 4: Next open "Zen Common Options" Step 5: Head down to "Custom Core Pstates" As you can see I left all above options on auto but you might want to force enable "Global C-State Control" Step 6: Accept the terms (this is no more dangerous than a fixed all core overclock so don't worry) Step 7: Pstate0 will be set to auto by default, change this to custom Step 8: Setting Pstate0 to custom reveals 5 boxes, 3 of which can be changed by the user and the top 2 greyed out boxes show the results. It gets a little complicated here because we are using hexadecimals. we are going to try a 3.9GHz overclock in this guide. Change Pstate0 FID to "9C", do not touch DID or VID, DID is the divisor there is no need to change this and VID is the voltage. We could change VID but at the moment anything different from the default VID breaks it and it will boost 100% of the time. (3A on my 1700 - if this is different for you please use YOUR default value NOT mine) I will add a table to calculate your FID values soon TM File is now attached: Ryzen Hex Values.xlsx Note: Voltage is in micro volts so that is 1.187500V and not 1187500V (Take a note of this number btw it will help later for the offset) LEAVE ALL OTHER P STATES ON "Auto" Step 9: Head back to the extreme tweaker tab because we now need to set the voltage offset. Change the CPU Core Voltage to "Offset mode" and positive "+" Now from your manual OC which you have probably dont prior to this you will know what voltage you need to be stable at 3.9GHz, for me this is 1.3375V but its always good to be a little generous when using offset instead of manual so i'm going to allow 1.35V maximum. To calculate your offset voltage take the desired value and subtract the voltage value that you noted down in the previous step. 1.35V - 1.1875V = 0.16250V Note: My RAM speed and RAM voltage have defaulted to 2133 and auto, leave these as they are and redo your RAM overclock once you are happy with what we are focusing on here. Step 10 (Optional): Enter "Extreme Tweaker\External Digi+ Power Control" and give the CPU voltage and SOC voltage some load line calibration to reduce V droop, personally I like level 2. Although this step is entirely optional! Step 11: Boot! Yeah we aren't done yet sorry Change your Power plan to "high performance" (May also work for AMD Ryzen Balanced plan - untested) or "Ryzen Balanced" (now confirmed to be working) and edit the plan -> change advanced power settings -> expand "Processor Power Management" -> expand "Minimum Processor State" -> set this at 20% Change Log: 20/04/17 - Release 20/04/17 - Added Hex Value Calculator 17/05/17 - Minor Text Changes & Confirmation of Ryzen Balanced Plan

Hey Guys, i´m at the moment planning on building a new pc but i´m not too sure which CPU cooler to choose. I want to go with a ryzen 1700 and the water cooling i was looking at was the corsair H110i but some of my friends said that they dont work as good as expected because the pump is set in the CPU spot itself and not at the radiator. They told me to the 115i instead BUT that thing isnt for the AM4 socket so i am a bit in a dilemma right now. Can some1 of you help me? Thanks for an answer! (sry 4 bad english)

Sauce from ASRock themselves: http://www.asrock.com/news/index.asp?ID=3625 The marketing blurb: First the ultimate X299 board: The Fatal1ty X299 Professional Gaming i9 (pretty much confirming an Intel Core i9 lineup coming). Built-in 10 GBit LAN on the back, all the PCIe 3.0 X16 slots, 3 M.2 slots all of which are full PCIe 3.0 4x slots, and of course all the RGB. Others are also on their merry way, including the X299 Taichi. Next, the very impressive and super puny but oh my god powerful X299E-ITX/AC. ITX X299 board, 4 SO-DIMM DDR4 slots, wireless AC WiFi, 2 gigabit Intel LAN ports, 3 (yes, 3) M.2 PCIe 3.0 x4 slots, the lot. Oh, and the socket itself is about 1/4th the size of the entire flippin' board. On to something else that's ridiculous: the H110 Pro BTC+. An H110 board solely for mining bitcoin with PCIe 3.0 1x cards. This has 12 of them (alongside a full sized X16 slot). Finally here's the first of 2 AM4 ITX boards. This one is the Fatal1ty X370 Gaming-ITX/ac. AC WiFi, (what seems like) a 6-phase power setup, Dual HDMI ports, Intel Gigabit LAN, the lot, an M.2 slot on the back. The other one is pretty much the same (as far as I can tell from the press release), but with the B350 chipset (and logically a lesser VRM setup as we've seen with all other B350 boards, big or small). So yeah. Maybe there's more to come, but at least I'm exited about AM4 on ITX. But have to say, that X299 ITX board is impressive as fuck. No word so far on AMD's X399 platform. Maybe later, or maybe it'll be an entirely separate event later in June/July.

The board should be ATX form factor, ready for stable overclocking (I am going to pair it with R5 1600). Onboard sound is also an important aspect for me. There are 4 candidates. 1.Asus Prime B350-Plus 2.Asrock Fatality AB350 Gaming K4 3.MSI B350 Tomahawk 4.Gigabyte GA-AB350-Gaming 3 There should be a clear winner I think, and I don't know which one to chose. HELP!

I got confusion in reading this manual for Asus Prime B350M-A motherboard for AM4 chip. On Page 1-7 I see the following table where the devices which share bandwidth with other devices are mentioned. Fundamentally, how to read table, column wise or row wise ? I do not understand that 1) PCIE x16 shares pcie-lanes with what since in that column (an also the row) it is only one item as shared. 2) m.2, AMD promotionary chip, USB 3.0 and ASMEDIA chip share pcie lanes. Is that true ?

Whenever i try to click on something in my BIOS it just freezes for no apparent reason, my BIOS Version and build date are E7A33AMS.300 and build date is 3/09/2017, i haven't tried updating as i don't see how it'd be possible if it freezes every time i click something

These became pretty popular, considering they were the only AM4 mini-itx boards on the market. If anyone wanted to build an SFF pc using a Ryzen CPU, they were essentially limited to Biostar. However, there were some shortcomings with using this motherboard. For one, many people complained about the bios being pretty bad, with a lot of apparently being horribly translated from a different language. As well, many people complained about it not having wifi. Now, though, Asrock is introducing it's own mini-itx am4 motherboard. This board has wifi built in and also definitely uses a better bios than the Biostar board. It's a little more expensive, but you get some nice extras with it, such as the 8 5 phase vrm design (2 for SoC and 6 3 for CPU itself). I think that's it's nice that we finally have an am4 mini-itx motherboard from one of "the big 4." What are your thoughts?

So I have a KÜHLER H2O 620 liquid cooling an fx 8350 and its time to upgrade to Ryzen 1600 (https://pcpartpicker.com/list/3vyXqk). The bracket that holds it on Am3+ will not fit on Am4, BUT I found this bracket form corsair for their Hydro Series. http://www.corsair.com/en-us/am4-amd-retention-bracket-kit-for-hydro-series-coolers It looks very similar in design to the H2O. http://www.antec.com/product.php?id=2768&pid=17&lan=us I am curios if anyone has attempted to try this or knows if there is compatibility?

hi everyone, im already have ryzen 7 1700 (non x) . i planning to buy GSkill Flare X (2x8GB) DDR4 RAM. what the best "price to peformance" AB350 Motherboard shouild i pick for overclock my RAM ? im not gonna crossfire my current graphic card / vga, so i want to pick the best AB350 motherboard in terms of price to peformance. any suggestions of what motherboard should i pick? not the most expensive one, but good enough for the price i pay.

I am building a ryzen 5 1600 sytem and cant decide a MB. I was wondering since am4 is a growing platform if I should go with a Asus b350 prime because Asus is know to have more consistent reliability and bios updates. Or a MSI b350 TOMAHAWK since It has more fan headers, better audio among a few other thing and also fits my color scheme.

So i'm trying to enable HPET through CMD and I have no idea why this isn't working EDIT: yes i have tried it with the slash that's missing and it's still the same error

The title. Does XFR (on the 1500X) work with AM4 A320 chipset motherboards? I haven't found a good answer so far. I was going to buy the R5 1400 which is $20 less than the 1500X, but would it be a good idea to buy the 1500X for $20 more and buy an A320 motherboard for it for $20 less so essentially the same price overall, but better performance on the CPU if XFR is supported. I heard Ryzen is pretty much hitting a wall past 4GHz anyway, so should I just buy the 1500X and an A320 motherboard and be happy with it? (if XFR is supported) Thanks guys! -MegaVoltz

Hello I'm searching for a good ATX motherboard for my next build. The CPU will probably be a R5 1600. I started searching for B350 boards but like every board has something I don't like about it. The ceapest choice would be the ASUS Prime B350-Plus for about 80€ shipped since it's on sale at the moment. And I would would already need a fan splitter since this board has only 3 fan connectors (including the one for the CPU fan) and I have 3 case fans. This board is really inexpensive but I know that the R5 1600 with the board I'll buy will be used for a very long time if they don't break (and even if I upgrade to a better CPU, I'll probably reuse this combo). The MSI Gaming B350 Pro Carbon and Krait Gaming have good VRMs as far as I know. I want to OC the CPU but I probably won't push it to its limit. And the price difference between one of those two MSI boards and the ASUS Prime X370-Pro isn't that big and I really like this ASUS board. But it costs about 145€ and so the price difference between this one and their B350-Plus is huge. And even though I really appreciate all the additional features X370 board has, I'm not interested in multi GPU configurations at all and therefore pairing a X370 board with a R5 1600 feels a bit unreasonable. I also checked out the ASRock B350 but the RAM QVL isn't very big compared to ASUS QVL. I would like to hear your opinion on which mainboard I should buy and please leave a reason for your choice.

I have realized over time browsing PCPartpicker I realized that the Asus X370 Prime Mobo on the site says that it is not compatible with 3200 megahertz R.A.M but Asus's website says it is I know that the Ryzen platform doesn't like overclocked R.A.M but it was someway, somehow cheaper the 2133 megahertz R.A.M I already was going to use so post your errors you have found.

Just found a bug on the latest versions of the bios for my msi x370 sli plus bios. This affects versions 3.2 and up on the bios. The bug involves setting the multiplier in the bios. When a manual multiplier is set it will require the actual frequency and not the multiplier itself. So if you entered 3700 into the multiplier box it would put in a multiplier of 37 or a ~3700mhz clock speed. However, if you input 37 into the box it would display 3700 when you press enter and would show up as having a clock speed of 3700mhz in the os and the bios, but this would be incorrect. I think it would believe you are requesting a clock speed of just 37mhz and set the multiplier as low as the board supports to match your request which on my board is 15.5 or a 1550mhz clock speed even though it is displaying otherwise. This bug will become apparent if you use a monitoring program like cpu-z or ryzen master which will display the correct clock speed and multiplier of the board. This may not be a very bad bug as it can be solved by filling out all 4 multiplier numbers in the box before pressing enter, but can be frustrating nonetheless. Right now I can only confirm that this affects the x370 sli bios, but I have read of other people with b350 motherboards from msi having similar issues. If you have an msi motherboard you should probably check to see if it is effected. I do not know if this is already known and being fixed or not. Please let me know if it is.

Greetings! I have ~430 euros and I need a Ryzen 5 1600 + B350 motherboard which can overclock well (preferably ATX and red colour), and cheap ram that I can OC to at least 2933MHz. Give me suggestions please, I have no idea which one to pick! (I'm thinking Asrock Pro4 AB350)

Hi I just built my Ryzen 5 1600 PC. When I turn it ON the EZ DEBUG LED CPU light blinks once. After that it doesn't post or display anything. The GPU and other case fans work fine and everything runs fine but it doesn't display anything. I tried to clear CMOS, tried to switch different RAM sticks but nothing works.

CPU: Ryzen 1600 RAM: G.Skill Ripjaws V 2 x 4gb DDR4 3200 MOBO: ? Options: MSI B350M Bazooka MSI B350M Mortar MSI B350M Mortar Arctic MSI B350M PRO-VDH I can stretch my budget to msi tomahawk if its better. Any other brands of motherboards are either out of stock or still not available in the shop im going to buy. Your help is much appreciated

Biostar's new Racing X370GTN motherboard can now be found on Newegg for about $110. this is the first itx board for the am4 platform. for how young ryzen is, i'm impressed with how quickly itx am4 came around. as far as i can remember, there never was any am3+ itx boards ever. shame too. i would've loved to build a mitx system with a 8350. either way, i have a new build planned around the new biostar board. specs below: ryzen 7 1800x corsair h80i v2 aio liquid cooler biostar racing x370gtn 32gb g.skill ripjaws v 3200mhz intel ssd6 p600 1tb nvme bootup adata 512gb ssd for adobe scratch disk use 2tb seagate firecuda 2.5 inch hdd for games 6tb wd black for recording 8tb wd red for backups gtx 980 ti (looking to replace this with amd vega once it comes out) silverstone sfx-l 700w 80+ Platinum psu ncase m1 mitx case i've had my ryzen 7 1800x sitting on a shelf since launch. i can't wait to finally put my new main mini system together! hopefully everyone else whose been waiting to build an am4 itx system feels the same way!

I bought a Noctua NH-D14 off of my friend who bought it from NCIX 4years ago. He went back to get a proof of purchase from NCIX but then they didn't have it... Show how am I going to RMA or get a AM4 mounting bracket for free??? Can I get a free mounting bracket from NCIX since I can't get it though Noctua and NCIX didn't have the receipt or the build invoice? Also why do I need proof to get a mounting bracket?

Hey guys i was just wondering if the Corsair H100i V2 is compatible with AM4 out of the box? Like to I need to buy an extra AM4 bracket to make it work?

Does anyone know if their are any B350 boards with rgb lighting? I'm building for my friend

Hi, I'm upgrading my 3 year old i5-4600 based computer to a Ryzen 1700. Currently looking at getting the AB350M Pro 4 from ASRock. (http://www.asrock.com/MB/AMD/AB350M Pro4/index.asp#Memory) Under the memory QVL, it lists down "CMK16GX4M4A2666C16" under the Corsair LPX line. I got a pair of DDR4s on sale from Amazon a week ago but they're "CMK16GX4M2B3000C15". Main difference is the clock speed and timings, but also this "4A" vs. "2B". Anyone know what these two codes mean? Do you think the memory will still work fine in the mobo, preferably running close to its advertised speed? Thanks in advance!

Hi I have just built most of my new PC excluding CPU and cooler due to the fact I'm waiting on the 1600X, however I just wanted to check if all the fans and LEDs would turn on for a second like they do on my old z87 machine without a CPU, however I got absolutely nothing, not even the power LED on my RX 480 came on, is this normal behaviour for this board to exhibit without a CPU or do I have a dead component as I have gone over every connection and it all looks fine, thanks for your help and time

I'm looking to buy this stick HyperX 16GB DDR4 - 2133 CL14 288 HyperX Fury Black and I can't find it on supported vendors list. All I can find is support to 8gb and 4gb sticks... Can I overclock in the future?
