    I'm only an hour south of you lol. Was also excited for the game.

    I hope part availability gets better in Q2. I don't think the 6800 XT I ordered / paid for is ever going to arrive, has now been 7...

    Yep had it loose while I worked down the rest just to be safe. Brought it down to 304 last night. Tried 285 for 150ns, won't POST but I can try something in between.

    Dropped tRCDWR to 8 and tCWL...

    Passed 3 cycles of TM5. Might change config to 10-20 and test overnight. Gonna see if I can get latency down further, unfortunately a bit limited at max 1.36v :am:

    Passed 1000% HCI last night at 1900 FCLK. Looks like the IOD / mem controller on this CPU are actually excellent, these voltages are the lowest I've seen. I guess somewhat luckily, stability for...
  5. I've boiled down my issues to VTTDDR mismatch...

    I've boiled down my issues to VTTDDR mismatch with VDIMM. This board does not allow the two to match up in a way that most VDIMM settings actually work. Was tipped off by this post at overclock.net...

    Tried 1/2 FCLK and still couldn't train DRAM between 3866-4800 CL18-20.

    This post by elmor kind of confirms what I'm seeing. I believe it is a board limitation, he was only able to hit 3666...

    Interesting.

    My board, RAM, CPU and I had a talk and decided to do the opposite of the rest of the internet. Apparently my IOD is special. Failed at 95% coverage this time, so making progress. I...

    I've come to terms with the fact that CH6 Hero is probably not the ideal motherboard for overclocking memory being a T-topology board and the VTTDDR voltage is adjusted in 0.0066v steps while VDIMM...
  9. Clock speeds on the new 5000 series with PBO +...

    Clock speeds on the new 5000 series with PBO + Auto OC are insane - biggest thing is it seems like they are way easier to OC that way and looks like the MT clocks hold up to whatever you could do...

    Have learned some about Zen 2's quirks tonight...probably should have picked one of these up a long time ago.

    PBO is not useless but with some settings it seems useless / will perform worse than...

    I'm on a 360mm AIO with decent temps, idle 29c, ~50-55c ST load. Batch 2018 PGT (after XT launch chips) so was hoping for a little better - CHVI Hero latest BIOS. Might go 5000 series later, not sure...

    Got a 3900X open box at Micro Center last month for $340. Not a great chip but stable at 4450/4300 CCD1/2 at 1.306v, 1900 FCLK 1.12v SoC with a 360mm MSI AIO. CCX0/1 are equal and CCX2/3 are equal,...

    I have a 3x AM3 CPUs that were nearly destroyed about a year ago (20+ bent pins each) by a family member that broke / stole / sold a bunch of my stuff including my newer GPUs. Was using HD 5770 again...

    Yep, I think this is an issue of "Oh, we're paying this money out and you're still going to have AMD designs anyway? Screw it, we're not going to pay you anymore."

    All subtimings identical? A lot of subtimings are set by the motherboard or SPD / XMP profile if left to "AUTO" and can have quite an impact on performance. Something as simple as leaving geardown...

    At 2666 ratio and up, CL automatically rounds to the next nearest value. 3200 CL12 looks like it would be the fastest option for you.

    You may also find a DRAM hole where it will not post on a...

    Tonga and Fiji have improved frame buffer color compression which is probably why you see less memory use / more efficient use on Fiji vs. Hawaii. AMD Touted 5-7% performance improvement from the R9...

    I like it. Looks like I'm gonna have to put in work to get 2666+ working and stable. I should have clarified, 3200 CL12 is 32M stable on air @ 4G, CL11 was a no-go and high BCLK was a no go, just...

    Unless you are extremely lucky with your IMC and RAM, there is probably no way you'll be able to run 3733 MHz at CAS 15. 3600 CAS 16 might be feasible on single rank.

    It is, but its also fun. This is more tinkering than I've ever done on another platform, even intel. I don't think this kit is going to do any better in 32M, just can't get tight enough. Seems...
