Those are high density. I tried 2x8gb on this board working well 2933- 3100mhz. Depends on blk and divider to what maxes your cpu and mem. I did not try 2x16 though on this board I would suggest with current micro code not working well.

Thx for the info looks like i am doomed then with 4 sticks

 

[Troezar]

Thanks, returning my order as system won't be bootable and motherboard is underpowered.

Won't it just boot initially at the default RAM speed then you set your RAM to its max speed?

Very impressive. Check out Witcher, the 1700 CPU1 is getting bashed 90%+ whilst 7700K split across more cores, yet the 1700 was keeping up.

GTA the 7700k 80-90% usages on all cores, 1700 much much lower. That game really does use moarrrr coressss.

I find that video very impressive considering it AMD Ryzen 1700 (3.9GHz) versus the i7 7700K (5GHz). With a 1.1Ghz speed advantage, the FPS gap was minimal.

I am sold!

Agree large gap there but the 1700 keeps up

Cat I understand exactly what your saying but to be fair those people that go so far as to read reviews of CPUs understand the nuances. They're either happy to wait or just looking for a reason to throw around on forums to dis AMD. It will always be this way, they are the underdog.

The masses will buy what they know it see heavily advertised, so Intel an Nvidia. Even if AMD are twice as good they will still buy what they know, they did back in the Athlon era. They won't remember the first hyperthreaded Intel CPUs having issues in three same way, it's like the Apple religion there's no reasoning

Server and OEM take-up is the most important. The enthusiasts won't care as they don't have at 1080p and understand that in a few months this will be a past issue.

I enjoy your posts but don't have a heart attack over it, it would be a lot less fun around here if you popped your cloggs!

Well I hope with the windows patch in a few weeks,better motherboard BIOS support,and more people aware of the SMT issue(probably lack of support by devs and MS),the 4C and 6C parts will look relatively better for gaming. I just want AMD to be more on the ball regarding those launches.

 

[nashathedog]

Never underestimate AMD's desire to stick it to Intel. I remember back when Quake 3 was the biggest title going and AMD launched the K6 CPU series, they paid people to write a patch for Quake II to add support for their "3DNow!" instruction set, and that was no small task considering Quake II had multiple API options (Software, PowerGL, OpenGL, Glide) and each one needed reworking.

That's good to hear but todays games are a lot more complex and I imagine it'd mean digging deeply into the engine code, that said I don't know enough about it other than too say I find working on the 10 year old X-ray engine is more than I can handle, So thank God AMD haven't employed me

I very much doubt this is working on this board currently. Although I did not try it... Only the odd board I tried is... If it is single sided 2x2 configuration for sure only way.

Well according to the official qualified vendors list for the board on GB's site they have validated that the CMK32GX4M2B3200C16 kit works in the board and that XMP works, I would assume it to be the case if they are listing it for compatibility :S

Jayztwocents lol. Oh dear...

For me 7600K 5G is beating 4G ryzen in gaming. Oc on ryzen currently 24-7 not going to go past 4.1 without binning.

For efficiency ryzen 2400 mems to 3000 mems is like 150-200mhz cpu speed depending on app. AMD should have realised this and gone super efficient.

Not a fan then?

Heh, he's fun but a bit American nutty?

This means I can game at 1440p, stream my game, record game, while my linux vm is downloading torrents without any frame drops..... I cannot do this on 4 cores well....

Whats your current processor?

 

[Mei]

yeh this is the problem with some of these tests, not many play games with NOTHING running in the background?
you have steam, you have other game launchers, maybe some twitch, maybe discord or skype
i have all that at least....

 

[brigantium]

Is that something that will be fixed in time/BIOS updates?

The Gigabyte Gaming 5 supports 3200MHz out of the box, I assume other boards just need fixes/updates and it won't be a permanent issue?

Maybe next revision of the motherboard, even with newest private BIOS version http://www.pcworld.idg.com.au/review/gigabyte/aorus-ga-ax370-gaming-5-amd-ryzen-motherboard/615222/

 

[awaybreaktoday]

Whats your current processor?

4790K. Looking forward to having 9 node kubernetes vm environment on running on 8 cores while recording high quality vids of stuff i am doing.....

Mmm... Throw everything at it.

Those looking for more comprehensive 1700 overclocking review.
http://www.xtremesystems.org/forums/showthread.php?293130-Ryzen-Return-of-the-Jedi

I posted that link in the motherboard section earlier, PWM implementation (6+4) is poor on the Gigabyte AX370-GAMING 5 it seems - having to use a fan over them to reduce the risk of fire while overclocking, also no BCLK overclocking, only on the K7.

Does the AX370-Gaming K7 use the exact same PWM's?

Memory seemed good - G.Skill 2x8g PC3200 14-14-14-34 1T XMP loaded running 1700 @ 4GHz stable.

Motherboard im using and motherboard vendor rants in general.

This board is underpowered first off. Its also a gaming 5. theres already a 7 on the site. I hope it does not share the same pwm as this one.

This board has no clock gen chip therefore bclock is locked. Who cares right? wrong. In order to extract the most performance from Ryzen you will need to clock bclok up past 100. Max memory multipler is 32 and I can not confirm but in cpu-z NB is always equal to ram. If indeed that is NB frequency to extract even more performance will require us to push the memory to beyond 3200 to get the northbridge frequency up.

Boards in general. I was benching 3d game tests at 4.2 gig. I could not pass cpu tests at 4.2. Had the board had a simple tweak it or msi oc knob or any type of button to dial the bclock frequency up during game tests and down during cpu tests I could have gotten a better result.

Unfortunately vendors have decided to screen print boards add lights and install heat trapping devices over PWM sinks that don't even adhere to the simple law of HEAT RISES.

Im very dissapointed and when i was working with vendors i would reccomend at least a little common sense and funtional features that helped overclockers.

To be continued. I need some sleep. I will rattle off whatever bugs i forgot this board has when i get up and workarounds i have found to get around them.

Gigabyte G5

bclock not 100. no workaround up to bios team.

SMT disabling bug. When enabling SMT again posting and going to windows don't go Oh @#$% I think i killed my chip when threads do not come back in windows. simply shut down, power off psu till power light goes out. switch back on and boot.

SMT disabling bug 1700 model. when disabling SMT and posting you lose overclock. Don't panic click the cores tab and you will see all cores but 0 are still at there overclocked speed. Open ryzen master. clock core 0 up. Problem reported and pending bios update.

General gigabyte post cycles. Try not to change to many settings at once. example c and q off smt off set ram speed and tune timings. Do one at a time save reboot change next. for as long as i have used gigabyte board they still do a funky reboot cycle dance. This gets around that unless you have a serious problem. I have gotten block up on boards that have hated bclock changes by doing this ( p67 ) all the way up to 110. 1 step up reboot. another step reboot.

Aorus cpu-z bug. SMT disabled shows only 4c/4t tabbing the cores shows two logical. workaround = dont use aorus cpu-z. the normal cpu-z reports it properly.

More info to come but i need sleep

Being validated for the board is only half the battle.

 

[awaybreaktoday]

Mmm... Throw everything at it.

Its not throwing everything at it. Some people do more than just run one game at a time on their system.

No, I know but nearly everyone wants a real workhorse so you can throw everything at it so it wont bog down. I can't blame them. Smooth performance everywhere.

 

[SiDeards73]

Hmmm bought some Ripjaws, 16gb, 3400mhz Cas16 a few days ago as i spotted them on a cheap offer, might have to send them back it seems... unless Asrock Taichi supports them, im not even sure if they are single or double sided, if they are double sided they are definitely going back

 

[Panos]

Possibly the only honest review, showing the systems running side by side on a GTX1080
Especially impressed given that the 7700K runs at 5Ghz and the 1700 at 3.9. And while the 7700K is trying hard, the 1700 keeps up with 2/3 of the CPU snoring going nothing. On some benchmarks half the cores are at 0%!!!!!

However did anyone realised that the games were smoother on the 1700 compared to the 7700K? And it looks isn't only me who realised that, there is a whole discussion under the video about this.
