    Future of CPU prices: AMD and Intel?

    CPUs were still cheap back when Intel and AMD were in fierce competition (Netburst vs K8). Competition leads to lower prices, not higher. Intel already have a 4.5 GHz (Turbo), 8-core CPU with 10% higher IPC, at $599, so that's the absolute highest price AMD can go with for the next 8-core CPU...

    Techpowerup：Intel Says AMD EPYC Processors "Glued-together" in Official Slide Deck

    Also, suggesting (well screaming from the rooftops, actually) that Epyc is using 4 "desktop" die is just incorrect. Zen was designed primarily for the server market. If anything, Ryzen consists of 1 "server" die. AMD's "glue" in the form of Infinity Glue Fabric is pretty good compared to...

    Ryzen 7 stability

    No crashes or BSODs here except when I was playing with higher memory speeds (3466 and 3600). Though I don't use sleep mode so I can't comment on that. If it only crashes in CPUID, it might be a compatibility issue (old version of CPUID?). However if it's generally unstable, it could be...

    Yeah it will probably work, even if you flash while overclocked, but like I said, it's 5 minutes work to potentially save you weeks of headache.

    Working great on my board, but that's what I expected since 0803 Beta was also stable for me. This board seems to hit a brick wall beyond 3200 MHz on the memory, but I'm quite happy with 3200 @ C14. Remember to always "Load optimized defaults", Save, reboot, before you flash. Yeah, it takes you...

    Will be interesting to hear about your results. I can't do 3600, 3466 or even 3333 with my LPX 3600 RAM on the X370 Prime Pro. The AIDA64 memory stress test is what kills it. It fails after anywhere from 2 - 5 seconds at 3600 and 3466, to ~2 hours at 3333. You can go as high as 1.2V SOC and...

    RM can easily load one full core on my system on its own. Temp fluctuations are normal with Ryzen due to SenseMI. It depends on the motherboard, which sensor it uses and how it reports the temp.

    AMD RYZEN Builders Thread

    I'd suggest 1.4V DRAM and 1.15V SOC for a start, and then if it's stable try to reduce those if possible. Also, try 16-16-16-36 rather than Auto for the timings. It should be possible, but then again, RAM support on the Prime X370 isn't that great compared to other X370 boards. At 3466 you're...

    How fast is your CPU at running the AMD Blender benchmark?

    Well it seems everyone is running different versions and render settings so hard to compare any results.. FWIW, running 2.78c and just opening the file and hitting F12, I got 23.86 seconds. 1800X @stock.

    So I tried the AGESA 1.0.0.6 Beta BIOS that just came out for the Prime X370. So far the results are a little disappointing and not as good with the Asus Peasant Prime X370 as the C6H and other high-end boards from what I've read. This is one instance where it would have paid off to get a more...

    The 0612 BIOS automatically sets SOC voltage to 1.1V when you engage DOCP (Asus-speak for XMP). This didn't happen with earlier BIOS versions. I manually decreased mine to 1.0V since that seems to be enough, but I guess there's no harm running it at 1.1V if that's what AMD recommends. I'm...

    Ryzen: if can't run full (3200MHz) speed, is DDR4-3000 CL15 faster than DDR4-3200CL16 b/c of the CL?

    Looking forward to trying the new AGESA on my X370 Prime and seeing if the improvements apply to the cheaper board, too. Definitively going to try running my LPX 3600's at their rated speed, or if that doesn't work, at least aim for 3466 MHz, and I'll also give my old LPX 3000's (3000 @ C16...

    Ryzen: if can't run full (3200MHz) speed, is DDR4-3000 CL15 faster than DDR4-3200CL16 b/c of the CL?

    Yep, but keep in mind that actual bandwidth does increase with clock frequency, even if latency is the same. So 3200 C16 is still "better" than 3000 C15, and requires a better bin. Ryzen also has this "peculiarity" where the inter-CCX communication latency and bandwidth are linked to memory...

    no 802.11ac in a smartphone....does it matter?

    I get over 65 MB/s between my computer and NAS over 802.11ac which is ~550 Mb/s. It also depends on the quality of the wireless card and antenna. You probably wouldn't see that on a phone with a small integrated antenna even if it had 802.11ac.

    Ryzen: if can't run full (3200MHz) speed, is DDR4-3000 CL15 faster than DDR4-3200CL16 b/c of the CL?

    Ryzen only supports even CAS latencies, so only C14, C16, C18 etc. You would have to run the 3000 C15 memory at 2933 C16 (or C14, if you manage to get it stable). 3200 C16 is probably a slightly better bin than 3000 C15. New BIOS/AGESA updates are improving compatibility, but it still pays off...

    Will be interesting to see whether it will allow me to run my LPX 3600's at the rated speeds. Since I have Asus Peasant X370, I have a feeling it will just result in a boot loop, but we shall see.

    It's possible they have already figured out the problem and implemented a workaround. I'm hoping Asus will fix it with the next BIOS update. Several people in that gigantic Overclockers forum thread mentioned it to the Asus rep who posts there.

    AMD RYZEN Builders Thread

    If you have a board that supports custom DRAM boot voltages, like the C6H, you can manually set the boot voltage to 1.35V. The problem is only apparent on boards that don't support custom DRAM boot voltage (most low-end and mid-range X370/B350 boards), or if you set it to Auto instead of...

    That's definitely causing a lot of issues for people.

But it's kind of ridiculous that...

    Both those should be Samsung B-die, it's the only IC capable of those speeds. Even my Corsair Vengeance LPX 3600 C18 is B-Die. The 3600 C15 is probably a better bin than the 3200 C14, but the 3200 C14 should have no problems running 3600 at C16 - C18, providing the platform will actually be...

    2666 with 4 DIMMs of Hynix IC:s is still pretty decent though. Maybe the next AGESA update will unlock 2933 again. Apparently, there's already a beta BIOS with AGESA 1006 from Gigabyte, so it shouldn't be long until it gets officially released by all vendors.

    For Gaming i7-7700 or Ryzen1700?

    Agreed, 12 threads is more than enough for gaming, and the higher clocks can make a difference. Regarding RAM, I'd suggest just waiting a few more weeks. There's a new AGESA update coming, and if that improves things to the point that any old 3000 - 3200 RAM works at the rated speed, it will no...

    For Ryzen Owners w/3200 memory

    Pressing need? I need moar frames! Not overclocking the CPU, but getting 3200 on the RAM required setting SOC voltage to Offset mode, +0.025V, enabling DOCP mode and manually setting the timings to 16-16-16-36.

    Ryzen: Strictly technical

    It's ridiculous that Asus have reps answering questions and giving support for the C6H in forums threads, but they don't give a crap about the Prime. Sure the C6H is $100 more, but I thought that was only supposed to buy you more hardware features, not a private tech support team from Asus.

    AMD RYZEN Builders Thread

    I think it's just the CAS latency that needs to be even numbers, and if you try to select uneven values it will change them automatically (C15 becomes C16 etc.). However it doesn't hurt to play around with the timings. I use 16-16-16-36.

    Well now that you can actually buy 6 and 8 core CPUs that don't cast an arm, a leg and a kidney, more people are going to be buying them.

    SSD Unpowered Data Retention

    It seems logical that data retention would get worse with the finer manufacturing processes. There are simply fewer electrons, thinner barriers etc. My newest SSD uses 15nm TLC, and I wouldn't trust it with any important data whatsoever (it's just a Steam library drive). I probably trust my...

    I would hold out for a few more weeks. There's another AGESA update coming out in May.

I think Asus went...

    Max RAM speed with Ryzen without entering overclock mode?

    If stability with high speed RAM improves in general, then fewer people should have to bump the SOC voltage. However as stated, the increase is so tiny as to be completely negligible. 1.2V vs 1.35V was referring to the RAM sticks themselves. The DDR4 spec calls for 1.2V, but high-speed memory...
