Upgrading from 1700X CPU to 2700X. Comparison tests in DCS SOON

Yes, maximum OC I achieved, but the 1700X was caped at 3.9, it was a bit of a dud.

Nice comparison! Thank you very much for your work!

A VR-Test would also be cool, but the results given in your test suggests that even with a 2700X the bottleneck in VR will be the GPU. Besides the better min FPS i don't exspect any major improvement over the 1700X.

I have an Ryzen 5 1600 non X running at 3700Mhz and a MSI 1080 Gaming X (non ti) but that combo works out pretty well in VR. So, with one of the cheapest CPU i can run DCS VR very decent!

So all in all it's a nice confirmation, that the choice to buy a cheap Ryzen instead of a not so cheap 7700K was a good one ;)

It wasnt a cheap System. :D

I bought NVME, 500€ worth of RAM and 800€ worth of graphics card.

But it was still cheaper than if I had gone the way of Skylake X CPU and respective (way overpriced and ill designed ) Motherboards.

I was considering waiting for this year but prices of many components went up so hard that buying in 2017 and spending another 300$ with this CPU might actually saved me money.

Didn't mean your system, i was refering to my system with my R5 1600 and the 1080 :smilewink:

I spend 190€ for the CPU and less than 500€ for the 1080...good ol times (Summer 2017 :cry:)

I wonder what benefits will I see compared to my current system. Before the weekend I've preordered R7 2700X, Crosshair Hero VII, G.Skill 3600 Mhz Cl15 B-die kit and Samsung 960 Evo M.2 SSD.

2600k sits normally OC'ed to 4.8 or 5.0 Ghz, but memory is very bad in this one. So until the above glory setup arrives I keep reading threads about overclocking, precision boost override and memory overclocking to figure out where it may get me.

Ryzen 2000 series seems to fix a lot of the gaming performance shortages seen with Ryzen 1000 series from what I've seen in various reviews. My own experience with the 1600x before moving to the 8700k suggested RAM latency was one of the biggest killers in a few games (not all, just some). Seems they got that sorted.

Of course, the single most important issue is its mining performance. :PAccording to UFD Tech, the 2700X is around 25% better at mining than the 1700 at 4.0 GHz, which was already a beastly miner. This is due to reduced cache latency mainly.

So I just got a Ryzen 2700 (non-X) yesterday, and happen to be in VR. I am coming from a OC'd i7 4790K @4.6Ghz. The Ryzen is pretty much on par with it in VR at 4.0Ghz. I ultimately made the move to Ryzen because I was streaming in VR, and GPU encoding on top of VR is a bit too much all at once for the 1080ti.

Established 24/7 settings

CPU V=1.4V Load level calibration 3

SOC 1.1V

VDRAM=1.4V

Timings 16-16-16-32 CR 1 @ 3533 Mhz (geardown mode enabled)

Nice !

for comparison, I did a 5.2G run and got 1666cb with RAM at 3200.

I would need 5.6G to match your 2 more cores at 4.2, astonishing.

Looking at how much work and effort had to be put in both CPU's to bring those numbers I can only say the AMD clearly wins, out of the box, some tweaks and GO !

With my Intel, oh boy, delid, grease, relid, PRAY...haha.

For me, the AMD is the winner as it is achievable with far less means and money and the trend goes towards higher res and VR and multicore. The clockspeed advantage is declining and need is declining.

I really wanna see TR2, that could be my next hoppa ,)

3533 should really work on something like Cl15 or Cl14 even if you have a good chip. I took a different path and right now run 2700X with features enabled on Asus motherboard, so its as follows:

CPU PE2 enabled with -0.04375V offset (all core 4.05 Ghz, single core 4.3 Ghz)

SoC 1.1

RAM 3466 mhz CL14 Low Latency setup at 1.4V

The last one really makes me wonder whether DCS would benefit more from a higher frequency of the ram or perhaps tighter timings. 3466 low latency is supposedly the best of both worlds. I know some people can get 3600 mhz at CL15 but my chip to get something useful of that would require a lot of tweaking and voltage. Its unstable beyond 3533 mhz so I've decided to step down a bit and get tighter timings.

Im running 4x8GB sticks, cannot run CL 14 @ 3533. Maybe 3600 CL16, I managed to boot on that but fails under stress testing. I'm waiting on better BIOS for more extensive trials.

I see. Well, with all four dimm slots occupied you will have issue reaching higher frequencies. Still, your score is very fine if its 4 x 8 Gb. With Ryzen 1 that could be tricky if not impossible to achieve. Your IMC must be better binned than mine in this case.

My stupid Asus board refuses to boot the 4 modules I have with XMP_3600_16-16-16-36-2T, it's a pita.

The fastest I can get reliable without BSOD is 3200MHz with 4 Modules.

The board instantly goes XMP with only 2 Modules, but I am not gonna throw out 16GB to achieve XMP.

Those IMC's are really tricky, lots of luck and many variables.

I hope, one day, they'll run 3600/16 again.

Bahhhhh

might need to increase memory controller voltage a twidge,

We had that issue on the FX Series as well, 2 Sticks was always stable out of the box,

4 Sticks required a bump in IMC Voltage in bios.

Skate,

thanks for the tip, I am really trying to find the right Voltage therefor. VCC-IO and VCC-SA usually are responsible for that. I have tried from default 0.95 and 1.05 up to 1.3 and 1.35 IO and SA.

Nothing gave me stability. Some Voltages post fatser than others, kinda like that. You do feel you are at the right dial..but it just wont yet

I dont know what it's called on the new boards, but on the 990FX it was literally DRAM Voltage or IMC Voltage

There is sadly no direct IMC Voltage.

I can and did raise the actual DRAM Voltage from 1.35 up to 1.45. But that also only helps the post beep to come faster, in the end, it fails memtest or crashes shortly after login in 10.

I am not giving up LoL...hell no...I may play the Volt Dials now...HAHA.

I'm pretty sure the SOC voltage option is for the IMC for Ryzen.

Not only, it also includes the northbridge and the connections to the south bridge. So when you set the voltage to the SOC your applying voltage to multiple points of possible failure.

8700k here...

almost got there.. 8:35min memtest until failure moving blocks....

yaaaawn...oh man..till 3am

these are my stable settings for the memory if anyone was wondering.

Inspired by Skate's call for more VOLTS and a new Bios from today I went for it again.

It won't boot the XMP as it is but I managed to boot 3600-16-16-16-36-2T at 5G and perform tests. Slowly getting there. Aida still drops after 15-20min but no BSOD other than my plague.

I think once I think THIS IS IT I will blank the drive and reinstall 10, those BSOD are never the same and do happen at stock settings too. PowerPlan might be it but I am not sure.

Time to play Tabula Rasa soon

...can't believe it boots 3600 and wont say " ME Firmware not loaded bla bla.."

edit: forgot to say: vDIMM is 1.40V and IO and SA at higher than usual settings. Overall more Volts.

Those individual dials are tricky indeed. Let me explain what they did for me.

When I leave it all on Auto/Default and only switch to XMP my Bios crashes after posting when it should boot the OS. I get a "ME Firmware Oplock..blabla failed..bla.." message. That comes from Auto pushing VCC-IO and VCC-SA above the limit of 1.25v each. If I go any higher than that the Bios will stall...and a PSU off/on is needed. Also Posting and Beeping can take MINUTES to take place. The closer you are to the real deal with IO & SA the FASTER your board beeps after you switch it on and the faster it will POST after beeping. Those 2 timeframes are a good indicator where you are heading to with your dials. Once I had it booting with IO & SA at 1.20v it still BSOD'ed in 10, also posting and booting was not as fast as I wanted. Not slow but not fast enough. So I upped the vDIMM from 1.37 to 1.4 and posting and beeping speeded up another 2-3 seconds and BSOD went away tho in priming and Aida it still threw away cores.

All at 5G-3600-16CL btw. I played the dials to catch the cores, but no dial fixed it. Not more vDIMM and not vCORE, tweaking IO & SA again got me the Bios lookup again...hmmm !!??

OK, what about all Volts back to where it was best and move LLC2 to LLC4 ?

--> BINGO !!! That was it. Instant Beep & Post like never before and no more dropping cores or crashing Aidia to red. NICE :)

All in all, it's quite easy once you have the values:

1: IO & SA have to be tuned manually, Asus plain overvolts those circuits and causes a bad Bios lockup. 8th gen i5/i7 do not like much over 1.2x Volts on each. 7thgen liked till 1.38 and loved it, this one will tilt. Those two dials need to be SPOT ON !

2: vDIMM: my 4 Modules wont boot with 1.35v, 1.37 starts to boot and beep, 1.4 actually works.

3: LLC...well..this is tricky and really depends on your very own silicon and SVID behavior.

Up to 3200MHz I do not need more than LLC2 but with 3600 nothing fixed it but 2 steps higher and LLC4.

So far so good.

As a side note: There is a nasty Windows10 bug present, maybe only Asus motherboards ( that I dont know ) but it is confirmed by Asus to [H]ard|OCP.

The reason is unknown but there is a workaround. If your system BSOD's with ever changing messages and reasons, under idle or load, after 3min or 2h, random..since 3 weeks circa..then maybe you suffer the same bug.

To bypass it, cycle your Power Settings around after logging in. That seems to fix it for that session. You need to remember when rebooting..If I dont..BANG...2-3h usually and it just BSOD's and reboots. When I follow the fix..it runs without issues. this happens with ot without oc, woth old and new Bios and old Build and newest Build.

Stability BSOD's and reboots have a different flavor, so I dare to call my rig stable with 3600 despite I can produce BSOD's if I dont cycle the powerplan from Balanced to High Performance and back or so. That's all it needs.
