    G.Skill 3200 C15 not running well on C6H

    in Ryzen | Bristol Ridge AM4

    Posted · Edited by Masterchief79

    Be advised bclk is strapped to PCI. Many devices will not like high PCI, some will corrupt some will break. Including onboard devices hard drives vga.......

     

    Best to disable all when "benching at high PCI"

     

    SOC may help stabilize IMC with 4 dims, no clue ( don't have 4 dims ) but with 2x8g single sided Samsung B die 1.0 is fine.

     

    Thanks again.

    I know the Refclkis strapped to all the internal devices but the Asus C6H and the Gigabyte X370 K7 IIRC use a second, external chip to take over clocking those devices. So as soon as you clock the refclk higher than 105MHz, for example the PCI-E clock, will get decoupled from the main bus clock and clocked via another chip. I read this somewhere, tried to find the source but no luck. Will look into it further when I have more time. It would make sense though.

    Edit: It was this news. It's in German unfortunately but it basically confirms what I said. If somebody's interested, just try google translate I guess.

     

    Regarding the SOC voltage: I know this was unnecessary but 1,2V was deemed safe by a lot of sources for benching and I just didn't want to take any chances. It's still useful information, for 24/7 I will wind this down to 1,0V or whatever turns out to be stable.

     

    Also, AMD announced new ram ratios in may, don't know if this was publicly known already. Was on their blog.

    Alright, thanks for advice. My sticks are singlesided, I pulled them out and had a look. Also thanks Infrared, that's some useful information.

    It turns out my CPU had this memory "hole" a little earlier than expected (this is described in the Asus C6H OC Guide). For me, 3100-3400MHz are a no-go, but 3500MHz booted flawlessly. *facepalm*

     

    I could even get some good latencies out of those. I ran SuperPi 32M at 3520MHz CL13-13-13-32@1,425V 1T if I remember correctly.

     

    Another thing I noticed is that with anything above 105MHz BCLK my M2 SSD stops working (960 Evo). So for testing the memory I had to install a fresh Win10 on a SATA SSD. Also, now that I have this sorted out, the M2 performance is in the bin, so the issues don't quite stop for me there ;(

    This btw also means that I can't run my memory on its specification because for 24/7 I can't go higher than 105MHz BCLK (because PCI-E 3.0 doesn't work above that) and I can't clock it between 3100 and 3400MHz. So I'll just have to stick with 2933MHz CL13. Ah well.

    Hey guys,

    not really satisfied with my memory performance so far so I'm asking you for help. It's 2x8GB of this one, I bought it because TridentZ were supposed to run great on Ryzen as they are singlesided and single rank (at least the 3200C14 are, so I figured mine are probably too, right?)

     

    So, here are my problems with it:

    • It doesn't run 3200 CL15, maxed out at about 3100MHz - more and I get "0d" when booting.
    • It doesn't really seem to run stable, at 2933MHz CL13 it seems to negatively impact my Firestrike Combined Score
    • I can't adjust subtimings in the BIOS of my C6H. When I set TRC to 50 for example (which is default by SPD) it still stays at 69, according to CPU-Z and MemTweakIt. I also can't adjust the fan speed in windows and a few other things. Maybe tools not working so well yet with 0902?
    • Somehow the Command Rate is at 2T?! I thought this was a 1T only platform.

     

    Things I have tried:

    • newest BIOS version 0902.
    • SOC voltage of 1,2V
    • memory voltage of 1,35V and more
    • booting with 3200C16 (still "0d")
    • swapping modules and slots around

     

    Hopefully you can help me eliminate these annoying things about this system. :D

    That's means CPU error afaik, like it can't be initialized, maybe too much contact pressure or dirt in the socket or whatever... Should be fine if you switch the coolers back and take the CPU out and in again. As long as you didn't break off any pins or something, permanent damage seems to be improbable by just switching coolers. Did you maybe pull the CPU out with the air cooler and damage it somehow in the process?

    Still be careful with the temps though. My Crosshair reads 45°C CPU Temp under prime95 @3,9GHz/1,3V. I can touch the back side of the board with my fingers though and even the back is hotter than 55°C I would guess. And keep in mind there's not even a good thermal connection between the CPU die and the mainboard itself. So the CPU should be at least at 65°C during that test, so it reads about 20K off the actual temperature.

    This is with the 0902 bios and the Sense Mi fix to 272 already btw.

    Thanks, will try that :)

    I would like to avoid 105MHz BCLK or more because you lose PCI-E 3.0 and I'm optimizing for 24/7 operation. So would be great if it would just boot with native 3200MHz and CL16, will report back.

     

    Edit: Unfortunately didn't work. Whatever I do, the memory doesn't work with anything above ~3100MHz. I tried native 3200MHz and also by BCLK. It shuts off for a sec, boots, goes F9 -> 0d and I don't get a post. No F9 cycle either. As I said, 1,2V SOC, 1,35V mem voltage, timings set to 16-16-16-16-35 this time, the rest was on auto.

    We went a little bit too far with the tweaking, probably future BIOSes will go back to 5803 behavior. You can manually restore this by setting the Sense Mi skew to 272 under Tweaker's paradise.

     

    Thanks for the reply. I set "Sense MI Skew" to enabled and the "Sense MI Offset" to 272 now. It's now showing 33°C in Idle with watercooling which seems reasonable.

    Edit: 44°C load still seems very low though (Cinebench, 3,9GHz@1,28V).

     

    Any tips for getting my ram working properly? It's G.Skill TridentZ 3200 C15. So far I got it working on 2933MHz CL14 but 3200MHz doesn't boot. It goes through the F9 cycle a couple of times and then stops on the "0d" error when booting. This was with the native 3200MHz multiplier and 100MHz BCLK, tried up to 1,2V SOC voltage on 0902. Ram timing manually set to 15-15-15-15-36 in BIOS with 1,35V. Maybe bad ram?

    Any idea on which PSU to buy?

    Hey guys,

    we all like a bit of extreme OC now and then, and I still have those 3 GTX580 sitting in the other room. Unfortunately, my 1350W Enermax went kablamo yesterday (this was already the second one).

     

    Maybe you guys can recommend me a solid PSU with 1000W+, modular cables and above all, good build quality and warranty? :D

    E8400 Binning question

    Posted · Edited by Masterchief79

    That's similar to my chip. 5GHz were possible at 1,45V as long as I didn't bench anything. This thing does have great clock for vCore scaling though. I'm gonna post a screenshot in a few minutes hopefully with another successful wPrime run.

     

    It did actually complete, this is pretty much as low as I can get the voltage. I guess this means good CPU? :) Btw, still room temperature, for some reason HWMonitor on the above screenshot reads the temps wrong. This is regular 20°C room with anything between 50 and 70°C CPU temp (can't get proper reading).

    Thanks, gonna check the voltage necessary for 4.5GHz. For stability, I'm just gonna use wPrime 1024M though, should be enough imo. Right now, it's running 4.5GHz 1,284V. I check back later and update you guys if 1024M did run successfully.

     

    Edit: Here's the screenshot. Note that this is not the lowest voltage possible, it was simply the first setting I tried.

    For FSB however, I don't think my board can handle more than 635 or so. Gonna try, but even if I use a PCI graphics card and overclocking the PCI-E bus to like 130MHz and stuff like that, I've never gotten it over 635. Not a 100% sure it wasn't the CPUs fault so I guess with this one my board gets another chance ;)

    E8400 Binning question

    Hey guys,

    what clocks would an E8400 E0 need to do to be considered bench-worthy? I have two new ones, and the first one I tested looks alright but I don't really have any measurements to base this on. I did bench two other ones some time ago but didn't keep any binning data.

     

    If they are good CPUs, I might get DICE one weekend and bench them properly. This was a pretest done at 1,45V for maximum clocks and FSB on my REX. Zalman air cooler at room temperature mounted with gravity and a book on top. Thus, the CPU got very hot at 1,5V+ which was the limiting factor in clocks I guess (80°C in Super Pi) - addind voltages didn't help either and I know the board can do more. The screenshots I attached show two results, wPrime also stable at both settings.

     

    Would be great if you help me to sort this in.

    Golden E6300 (and other 775 CPUs)

    Hey guys,

    couple of 775 stuff. Binned with 1,45V vCore and SuperPi 1M stability on my REX with both cores enabled, regular air cooling at room temperature.

     

    first up for sale my golden E6300. Here's what it can do: http://hwbot.org/submission/3060202_masterchief79_wprime___1024m_core_2_e6300_%281.86ghz%29_10min_4sec_312ms

    Incredibly strong core, completely stable at 4,4GHz@1,61V@-45°C.

    Unfortunately my board doesn't allow higher clocks, I'm sure the CPU can do more. It did around 580 FSB AT AIR!!!

    With LN2 and a 650+FSB board this should be gold medals all the way. B/O: 50€ - SOLD AND SHIPPED TO SALE_QUICHE.

     

     

    Q6600

    CPU seems to run pretty high speeds with low vCore.

    wPrime 32M: (score)

    wPrime 1024M (ignore bad efficiency): (score)

    These were at SS at about -40°C at evap, so there should be headroom with LN2. I have no experience with Q6600 binning as this is only my second one, but compared to the rest of the rankings it certainly seems promising :)

    B/O: 75€

     

     

    2x E6300. These did ~530 FSB/3725MHz which is also not bad and currently unmet by my other ~60 CPUs - 10€ each

     

    5x E6300. Nothing special, 500 FSB or less - 3€ each

     

    Also got a couple of E2140, E2160, E2180, E2200, E4300, E4600, E6600, E6750. Just tell me what you need, my binning setup is running and working so if you want results, just tell me.
